  1. Energy supply options for climate change mitigation and sustainable development

    Dobran, Flavio

    2010-09-15

    Modern society is dependent on fossil fuels for its energy needs, but their combustion is producing emissions of greenhouse gases that cause global warming. If these emissions remain unconstrained they risk of producing significant impacts on humanity and ecosystems. Replacement of fossil fuels with alternative energy sources can stabilize anthropogenic global warming and thus reduce the climate change impacts. The deployment of alternative energy supply technologies should be based on objectives that are consistent with sustainability indicators and incorporate quantitative risk assessment multiattribute utility decision methodologies capable of ascertaining effective future energy supply options.

    Climate is a critical factor shaping the structure and function of forest ecosystems in the Southern United States. Human induced changes in climate systems have resulted in an increase in the global average air temperature of about 0.8°C since the 1900s (Pachuri and Reisinger 2007). Data from long-term weather stations show that overall, the continental United States...

    Mitigation options to reduce greenhouse gas emissions and sequester carbon in land use sectors are described in some detail. The paper highlights those options in the forestry sector, which are more relevant to different parts of Africa. It briefly outlines a bottom-up methodological framework for comprehensively assessing mitigation options in land use sectors. This method emphasizes the application of end-use demand projections to construct baseline and mitigation scenarios and explicitly addresses the carbon storage potential on land an in wood products, as well as use of wood to substitute for fossil fuels. Cost-effectiveness indicators for ranking mitigation options are proposed, including those which account for non-carbon monetary benefits such as those derived from forest products, as well as opportunity cost of pursuing specific mitigation option. The paper finally surveys the likely policies, barriers and incentives to implement such mitigation options in African countries. (au) 13 refs.

    1998-10-01

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    Changes in consumer behaviour can lead to major reductions in greenhouse gas emissions in the European Union, particularly in the areas of transport, housing and food. Behavioural changes can complement technological changes and can allow emission reduction targets to be achieved more cost-effectively overall. The study identifies 36 options for behavioural change that would cut greenhouse gas emissions. Of these, 11 particularly relevant options have been studied in detail. They include shifting to a more healthy and balanced diet, eating less meat and dairy products, buying and using a smaller car or an electric car, teleworking, adjusting room temperature and optimising ventilation. For each of the behavioural changes studied in depth, emission reduction potentials have been quantified for 2020, 2030 and 2050. The study identifies barriers to implementing the changes, and quantifies the likely effects of policy packages which could overcome these barriers. The results show that the behavioural changes that could take place simultaneously have the potential to save emissions totalling up to about 600 million tonnes of CO2-equivalent a year in 2020. This is about one-quarter of the projected annual emissions from sectors not covered by the EU emissions trading system. The savings potential is particularly high in the area of food.

  14. The contribution of sectoral climate change mitigation options to national targets: a quantitative assessment of dairy production in Kenya

    Brandt, Patric; Herold, Martin; Rufino, Mariana C.

    2018-03-01

    Reducing greenhouse gas (GHG) emissions from agriculture has become a critical target in national climate change policies. More than 80% of the countries in Sub-Saharan Africa (SSA) refer to the reduction of agricultural emissions, including livestock, in their nationally determined contribution (NDC) to mitigate climate change. The livestock sector in Kenya contributes largely to the gross domestic product and to GHG emissions from the land use sector. The government has recently pledged in its NDC to curb total GHG emissions by 30% by 2030. Quantifying and linking the mitigation potential of farm practices to national targets is required to support realistically the implementation of NDCs. Improvements in feed and manure management represent promising mitigation options for dairy production. This study aimed (i) to assess mitigation and food production benefits of feed and manure management scenarios, including land use changes covering Kenya’s entire dairy production region and (ii) to analyse the contribution of these practices to national targets on milk production and mitigation, and their biophysical feasibility given the availability of arable land. The results indicate that improving forage quality by increasing the use of Napier grass and supplementing dairy concentrates supports Kenya’s NDC target, reduces emission intensities by 26%-31%, partially achieves the national milk productivity target for 2030 by 38%-41%, and shows high feasibility given the availability of arable land. Covering manure heaps may reduce emissions from manure management by 68%. In contrast, including maize silage in cattle diets would not reduce emission intensities due to the risk of ten-fold higher emissions from the conversion of land required to grow additional maize. The shortage of arable land may render the implementation of these improved feed practices largely infeasible. This assessment provides the first quantitative estimates of the potential of feed

  15. Selection of appropriate greenhouse gas mitigation options

    Ramanathan, R. [Indira Ghandi Institute of Development Research, Mumbai (India)

    1999-10-01

    Greenhouse gas mitigation options help in reducing greenhouse gas emissions so as to avoid the adverse environmental impacts due to global warming/climate change. They have different characteristics when evaluated using different criteria. For example, some options may be very cost effective, while some may have an additional advantage of reducing local pollution. Hence, selection of these options, for consideration by a national government or by a funding agency, has to incorporate multiple criteria. In this paper, some important criteria relevant to the selection are discussed, and a multi-criteria methodology is suggested for making appropriate selection. The methodology, called the Analytic Hierarchy Process, is described using two illustrations. (author)

  17. Reservoir operations under climate change: Storage capacity options to mitigate risk

    2017-12-01

    Observed changes in precipitation patterns, rising surface temperature, increases in frequency and intensity of floods and droughts, widespread melting of ice, and reduced snow cover are some of the documented hydrologic changes associated with global climate change. Climate change is therefore expected to affect the water supply-demand balance in the Northeast United States and challenge existing water management strategies. The hydrological implications of future climate will affect the design capacity and operating characteristics of dams. The vulnerability of water resources systems to floods and droughts will increase, and the trade-offs between reservoir releases to maintain flood control storage, drought resilience, ecological flow, human water demand, and energy production should be reconsidered. We used a Neural Networks based General Reservoir Operation Scheme to estimate the implications of climate change for dams on a regional scale. This dynamic daily reservoir module automatically adapts to changes in climate and re-adjusts the operation of dams based on water storage level, timing, and magnitude of incoming flows. Our findings suggest that the importance of dams in providing water security in the region will increase. We create an indicator of the Effective Degree of Regulation (EDR) by dams on water resources and show that it is expected to increase, particularly during drier months of year, simply as a consequence of projected climate change. The results also indicate that increasing the size and number of dams, in addition to modifying their operations, may become necessary to offset the vulnerabilities of water resources systems to future climate uncertainties. This is the case even without considering the likely increase in future water demand, especially in the most densely populated regions of the Northeast.

  18. Adaptation and mitigation options to manage aflatoxin contamination in food with a climate change perspective

    Wambui, J. M.; Karuri, E. G.; Ojiambo, J. A.

    2016-01-01

    Understanding the impact of climate change remains vital for food safety and public health. Of particular importance is the influence of climatic conditions on the growth of Aspergillus flavus and production of their toxins. Nevertheless, little is known about the actual impact of climate change....... We used a systematic literature review of review and research articles, with limited searching but systematic screening to explore available qualitative and quantitative data. Projections from the data, showed that on average, a 58.9% increase of aflatoxin contamination in the Central and Western...... parts and a decrease of 44.6% in the Eastern and Southern parts is expected but with several possible scenarios. This makes the impact of climate change on aflatoxin contamination in Kenya complex. To protect the public and environment from the negative impact, a regulatory framework that allows...

  19. Reforestation of Imperata grasslands in Indonesia as an option for mitigation of climate change

    Naess, L O [Center for International Climate and Environmental Research, Oslo (Norway)

    1999-12-31

    The paper discusses reforestation of Imperata (alang-alang) grasslands in Indonesia as one strategy to counteract the anthropogenically enhanced greenhouse effect. Large-scale Imperata grasslands, mainly formed as a result of deforestation and land use change, cover at least 8.6 million hectares or 4.5% of the land area in Indonesia. Reforestation of these lands has a large potential for carbon sequestration and could yield significant socio-economic and environmental benefits. However, there are at present several constraints and barriers to capturing these benefits. The global carbon sequestration benefits of reforestation must be considered jointly with objectives for local development and environmental conservation. A major challenge is to examine potential areas of synergy or conflict between global and local objectives. There is also a need for a more comprehensive assessment of how reforestation projects affect carbon flows and stocks. 45 refs.

    The report deals with a cooperation project between Norway and Indonesia dealing with a feasibility study on sustainable reforestation of degraded grasslands in Indonesia. Poor forest management and uncontrolled land use changes contribute a significant share anthropogenic emissions of greenhouse gases, especially CO{sub 2}, and one of many ways to reduce the CO{sub 2} emission is to encourage reforestation and better forest management. The report contains a brief overview of the issue of Imperata (alang-alang) grasslands, an outline of the present status, a discussion of potential costs and benefits associated with reforestation, and suggestions of strategies which could be applied to reach the desired goals. Case studies are presented from three locations where field work has been undertaken. The case studies provide baseline data about the sites and the imperata grasslands, experiences from earlier efforts to rehabilitate the grasslands, the common attitude to reforestation among the local communities, a discussion of the feasibility of reforestation, and finally, recommendations for the future. 142 refs., 11 figs., 15 tabs.

  2. Greenhouse gas mitigation options for Washington State

    Garcia, N.

    1996-04-01

    President Clinton, in 1993, established a goal for the United States to return emissions of greenhouse gases to 1990 levels by the year 2000. One effort established to help meet this goal was a three part Environmental Protection Agency state grant program. Washington State completed part one of this program with the release of the 1990 greenhouse gas emissions inventory and 2010 projected inventory. This document completes part two by detailing alternative greenhouse gas mitigation options. In part three of the program EPA, working in partnership with the States, may help fund innovative greenhouse gas reduction strategies. The greenhouse gas control options analyzed in this report have a wide range of greenhouse gas reductions, costs, and implementation requirements. In order to select and implement a prudent mix of control strategies, policy makers need to have some notion of the potential change in climate, the consequences of that change and the uncertainties contained therein. By understanding the risks of climate change, policy makers can better balance the use of scarce public resources for concerns that are immediate and present against those that affect future generations. Therefore, prior to analyzing alternative greenhouse gas control measures, this report briefly describes the phenomenon and uncertainties of global climate change, and then projects the likely consequences for Washington state.

  6. Regional air quality management aspects of climate change: impact of climate mitigation options on regional air emissions.

    Rudokas, Jason; Miller, Paul J; Trail, Marcus A; Russell, Armistead G

    2015-04-21

    We investigate the projected impact of six climate mitigation scenarios on U.S. emissions of carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen oxides (NOX) associated with energy use in major sectors of the U.S. economy (commercial, residential, industrial, electricity generation, and transportation). We use the EPA U.S. 9-region national database with the MARKet Allocation energy system model to project emissions changes over the 2005 to 2050 time frame. The modeled scenarios are two carbon tax, two low carbon transportation, and two biomass fuel choice scenarios. In the lower carbon tax and both biomass fuel choice scenarios, SO2 and NOX achieve reductions largely through pre-existing rules and policies, with only relatively modest additional changes occurring from the climate mitigation measures. The higher carbon tax scenario projects greater declines in CO2 and SO2 relative to the 2050 reference case, but electricity sector NOX increases. This is a result of reduced investments in power plant NOX controls in earlier years in anticipation of accelerated coal power plant retirements, energy penalties associated with carbon capture systems, and shifting of NOX emissions in later years from power plants subject to a regional NOX cap to those in regions not subject to the cap.

  7. Land use and desertification in the Binh Thuan Province of Southeastern Vietnam: mitigation and adaptation options now and under climate change

    Gobin, A.; Le Trinh, H.; Pham Ha, L.; Hens, L.

    2012-04-01

    Desertification and drought affects approximately 300,000 ha of land in the southeastern provinces of Vietnam, much of which is located on agricultural land and forest in the Binh Thuan Province. The methodology for analysing mitigation and adaptation options follows a chain of risk approach that includes a spatio-temporal characterisation of (1) the hazard, (2) the bio-physical and socio-economic impact, (3) the vulnerability to different activities as related to land uses, and (4) risk management options. The present forms of land degradation include sand dune formation and severe erosion (63%), degradation due to laterisation (14%), salinisation (13%), and rock outcrops (10%). The climate is characterized by a distinct dry season with high temperatures, a lot of sunshine and a warm land wind resulting in high evapotranspiration rates. Delays in the onset of the rainy season, e.g. with 20 days in 2010, cause a shift in the growing season. Damages due to drought are estimated at hundreds billion VND (US 1 = VND 20,8900) and contribute to poverty in the rural areas. The current risk-exposure is exacerbated further by climate change. Combined effects of desertification and climate change cause increased degradation of natural resources including land cover. At the same time land use changes are crucial in influencing responses to climate change and desertification. A further SWOT analysis combined with spatio-temporal analysis for each of the major sectors (agriculture, forestry and nature protection, urban and rural development, water resources and fisheries, industry) demonstrates a series of adaptation and mitigation options. Land is a valuable and limited resource. An integrated approach to land use and management is therefore essential to combat environmental hazards such as desertification and climate change.

  8. Climate change mitigation studies in Sri Lanka

    Wickramaratne, Rupa

    1998-01-01

    In Sri Lanka, Climate Change Mitigation Studies have received low priority and have been limited to an ADB-sponsored preliminary study followed by an initial assessment of some mitigation options in the energy and agricultural sectors, with technical assistance from the US Country Studies Program. The major focus was on options of the mitigation of carbon dioxide emissions from the energy sector. Owing to funding constraints, only the potential for reduction of carbon dioxide emissions resulting from the various mitigation options were quantified; analysis of monetary costs and benefits or policy/programs for adoption of the options were not undertaken. For the non-energy sector, a very limited study on mitigation of methane emissions from rice fields was carried out. (au)

    Gelil, I.A.; El-Touny, S.; Korkor, H. [Organization for Energy Conservation and Planning (OECP), Cairo (Egypt)

    1996-12-31

    Though its contribution to the global Greenhouse gases emission is relatively small, Egypt has signed and ratified the United Nations Framework Convention on Climate Change (UN FCCC) and has been playing an active role in the international efforts to deal with such environmental challenges. Energy efficiency has been one of the main strategies that Egypt has adopted to improve environmental quality and enhance economic competitiveness. This paper highlights three initiatives currently underway to improve energy efficiency of the Egyptian industry. The first is a project that has been recently completed by OECP to assess potential GHG mitigation options available in Egypt`s oil refineries. The second initiative is an assessment of GHG mitigation potential in the Small and Medium size Enterprises (SME) in the Mediterranean city of Alexandria. The third one focuses on identifying demand side management options in some industrial electricity consumers in the same city.

  12. Greenhouse gases mitigation options and strategies for Tanzania

    Mwandosya, M.J.; Meena, H.E.

    1996-12-31

    Tanzania became a party to the United Nations Framework on Climate Change (UN FCCC) when she ratified the Convention in March, 1996. Now that Tanzania and other developing countries are Parties to the UN FCCC, compliance with its provisions is mandatory. The legal requirements therefore provide a basis for their participation in climate change studies and policy formulation. All parties to the Convention are required by Article 4.1 of the United Nations Convention on Climate Change (UN FCCC) to develop, periodically update, publish, and make available national inventories of anthropogenic emissions and removal of greenhouse gases that are not controlled by the Montreal Protocol. This study on possible options for the mitigation of greenhouse gases in Tanzania is a preliminary effort towards the fulfilment of the obligation. In order to fulfil their obligations under the UN FCCC and have a meaningful mitigation assessment, identification and quantification of anthropogenic sources of atmospheric emissions of greenhouse gases in the country was undertaken. In this respect, the study of anthropogenic emissions by source and removals by sink of GHGs in Tanzania was done with the main objective of increasing the quantity and quality of base-line data available in order to further scientific understanding of the relationship of greenhouse gas emissions to climate change. Furthermore, the study facilitated identification of national policy and technological options that could reduce the level of emissions in the country.

  13. Climate change mitigation options in the rural land use sector: Stakeholders’ perspectives on barriers, enablers and the role of policy in North East Scotland

    Feliciano, Diana; Hunter, Colin; Slee, Bill; Smith, Pete

    2014-01-01

    Highlights: • Farmers are mainly willing to expand the uptake of mitigation practices they already implement. • Main barriers and enablers to uptake are physical–environmental constraints and personal values. • Farmers consider that agriculture is a “special case” because their function is to produce food. • Lack of incentives is not the main barrier to the uptake of mitigation practices. • Policies should allow differentiation, and mitigation measures should be integrated with other mechanisms. - Abstract: The rural land use sector could potentially mitigate a large amount of GHG emissions. Implementation requires the engagement of farmers and other land managers. Understanding the barriers and enablers for the uptake of these practices is essential both to inform policy-makers and to achieve effective policy outreach. In Scotland, the rural land use sector is subject to a greenhouse gas (GHG) emission reduction target of 21% by 2020 relative to 1990 levels. This study contributes to the body of research on stakeholders’ perspectives about suitability of climate change mitigation practices at the regional level. Mixed-methods were used to collect the data, namely participatory workshops with scientists and relevant stakeholders, a farmer questionnaire, and focus groups with farmers. Findings show that farmers were mainly willing to expand the uptake of mitigation practices they were already implementing because they consider these are the most cost-effective. Barriers to the implementation of mitigation practices are mainly related to physical–environmental constraints, lack of information and education and personal interests and values. Similarly, enablers are also related to physical–environmental factors and personal interests and values. Economic incentives, voluntary approaches and provision of information have been identified by workshop participants as the most favourable approaches needed to promote the uptake of technically feasible

  14. Mitigating greenhouse: Limited time, limited options

    Moriarty, Patrick; Honnery, Damon

    2008-01-01

    Most human-caused climate change comes from fossil fuel combustion emissions. To avoid the risk of serious climate change, very recent research suggests that emission reductions will need to be both large and rapidly implemented. We argue that technical solutions-improving energy efficiency, use of renewable and nuclear energy, and carbon capture and sequestration-can only be of minor importance, mainly given the limited time available to take effective climate action. Only curbing energy use, perhaps through 'social efficiency' gains, particularly in the high-energy consumption countries, can provide the rapid emissions reductions needed. The social efficiency approach requires a basic rethinking in how we can satisfy our human needs with low environmental impacts. Large cuts in emissions could then occur rapidly, but only if resistance to such changes can be overcome. Particularly in transport, there are also serious potential conflicts between the technical and the social efficiency approaches, requiring a choice to be made

  15. Potential GHG mitigation options for agriculture in China

    Erda, Lin; Yue, Li; Hongmin, Dong [Agrometeorology Institute, Beijing (China)

    1996-12-31

    Agriculture contributes more or less to anthropogenic emissions of carbon dioxide (CO{sub 2}), methane (CH{sub 4}), and nitrous oxide (N{sub 2}O). China`s agriculture accounts for about 5-15% of total emissions for these gases. Land-use changes related to agriculture are not major contributors in China. Mitigation options are available that could result in significant decrease in CH{sub 4} and N{sub 2}O emissions from agricultural systems. If implemented, they are likely to increase crop and animal productivity. Implementation has the potential to decrease CH{sub 4} emissions from rice, ruminants, and animal waste by 4-40%. The key to decreasing N{sub 2}O emissions is improving the efficiency of plant utilization of fertilizer N. This could decrease N{sub 2}O emissions from agriculture by almost 20%. Using animal waste to produce CH{sub 4} for energy and digested manure for fertilizer may at some time be cost effective. Economic analyses of options proposed should show positive economic as well as environmental benefits.

  17. Cost effectiveness of GHG mitigation options and policy implication

    Lim, K. S. [Korea Institute for Industrial Economics and Trade, Seoul (Korea, Republic of)

    1998-04-01

    This paper represents the summary findings and conclusions of several studies implemented about microeconomics and macroeconomics marginal costs of GHG abatement policies. Financial, economic, and, where possible, environmental microeconomics costs of reducing GHGs are estimated by a World Bank team. Six energy-related CO{sub 2} mitigation policy options are applied to estimate the macroeconomics costs of GHG emission reduction, the macroeconomics impacts on the Chinese economy. In terms of policy, conservation is a better option to cope with a restrictive mitigation constraint, assuming a developing country can achieve planned energy-saving targets. Without a CO{sub 2} emission constraint or with less restrictive CO{sub 2} emission constraints, however, the simulation results indicate that a conservation strategy may be less attractive than fuel substitution in a developing country, mainly due to the economic dampening effect of reduced production in the energy sectors. This finding suggests that an often-cited costless or negative-cost energy conservation policy may not be a better option when a less restrictive mitigation target is in force. This does not mean that the potential for energy efficiency improvements in a developing country is not worthwhile, but that the overall macroeconomics impacts should be considered before implementing the policy option.

  20. Climate change mitigation in China

    Xu, Bo

    2012-07-01

    China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. China's greenhouse gas (GHG) emissions, with carbon dioxide (CO{sub 2}) being the most significant contributor, have also been increasing rapidly in the past three decades. Responding to both domestic challenges and international pressure regarding energy, climate change and environment, the Chinese government has made a point of addressing climate change since the early 2000s. This thesis provides a comprehensive analysis of China's CO{sub 2} emissions and policy instruments for mitigating climate change. In the analysis, China's CO{sub 2} emissions in recent decades were reviewed and the Environmental Kuznets Curve (EKC) hypothesis examined. Using the mostly frequently studied macroeconomic factors and time-series data for the period of 1980-2008, the existence of an EKC relationship between CO{sub 2} per capita and GDP per capita was verified. However, China's CO{sub 2} emissions will continue to grow over coming decades and the turning point in overall CO{sub 2} emissions will appear in 2078 according to a crude projection. More importantly, CO{sub 2} emissions will not spontaneously decrease if China continues to develop its economy without mitigating climate change. On the other hand, CO{sub 2} emissions could start to decrease if substantial efforts are made. China's present mitigation target, i.e. to reduce CO{sub 2} emissions per unit of GDP by 40-45 % by 2020 compared with the 2005 level, was then evaluated. Three business-as-usual (BAU) scenarios were developed and compared with the level of emissions according to the mitigation target. The calculations indicated that decreasing the CO{sub 2} intensity of GDP by 40-45 % by 2020 is a challenging but hopeful target. To

  1. Risk Assessment of Arsenic Mitigation Options in Bangladesh

    2006-01-01

    The provision of alternative water sources is the principal arsenic mitigation strategy in Bangladesh, but can lead to risk substitution. A study of arsenic mitigation options was undertaken to assess water quality and sanitary condition and to estimate the burden of disease associated with each technology in disability-adjusted life years (DALYs). Dugwells and pond-sand filters showed heavy microbial contamination in both dry and monsoon seasons, and the estimated burden of disease was high. Rainwater was of good quality in the monsoon but deteriorated in the dry season. Deep tubewells showed microbial contamination in the monsoon but not in the dry season and was the only technology to approach the World Health Organization's reference level of risk of 10-6 DALYs. A few dugwells and one pond-sand filter showed arsenic in excess of 50 μg/L. The findings suggest that deep tubewells and rainwater harvesting provide safer water than dugwells and pond-sand filters and should be the preferred options. PMID:17366776

  2. Mitigation incentives with climate finance and treaty options

    Strand, Jon

    2016-01-01

    Future greenhouse gas (GHG) mitigation action of current non-climate-policy (NP) countries is considered to take two alternative forms: 1) “climate finance” payments received in return for future reductions in its GHG emissions below a defined “baseline”; and 2) join a “climate treaty” whereby the required emissions reductions are formally binding. It is assumed that baselines defining climate finance payments, and required emissions reductions under a treaty, depend positively on current emissions. It is then shown that making such future options available reduces current GHG mitigation in NP countries, leading to higher emissions in the short run. This effect is stronger when future climate finance payments are higher; the required relative emissions reductions under a treaty are greater; when commitments under a treaty are longer-lasting; and mitigation targets depend more on current emissions. Such short-run increases in emissions can (sometimes, more than) fully eliminate the effect of the subsequent policy. When climate finance and treaties are both future alternatives, more generous climate finance can make it harder and more expensive to induce the country to join a climate treaty. - Highlights: • A good future climate finance arrangement can increase GHG emissions today. • The same can be the case with a future and restrictive climate treaty. • These can be problems when costs under such solutions are reduced by higher emissions today. • Better climate finance also tends to make joining a climate treaty less attractive.

    There is a mounting consensus that human behavior is changing the global climate and its consequence could be catastrophic. Reducing the 24 billion metric tons of carbon dioxide emissions from stationary and mobile sources is a gigantic task involving both technological challenges and monumental financial and societal costs. The pursuit of sustainable energy resources, environment, and economy has become a complex issue of global scale that affects the daily life of every citizen of the world. The present mitigation activities range from energy conservation, carbon-neutral energy conversions, carbon advanced combustion process that produce no greenhouse gases and that enable carbon capture and sequestion, to other advanced technologies. From its causes and impacts to its solutions, the issues surrounding climate change involve multidisciplinary science and technology. This handbook will provide a single source of this information. The book will be divided into the following sections: Scientific Evidence of Cl...

  4. How will climate change pathways and mitigation options alter incidence of vector-borne diseases? A framework for leishmaniasis in South and Meso-America.

    Bethan V Purse

    Full Text Available The enormous global burden of vector-borne diseases disproportionately affects poor people in tropical, developing countries. Changes in vector-borne disease impacts are often linked to human modification of ecosystems as well as climate change. For tropical ecosystems, the health impacts of future environmental and developmental policy depend on how vector-borne disease risks trade off against other ecosystem services across heterogeneous landscapes. By linking future socio-economic and climate change pathways to dynamic land use models, this study is amongst the first to analyse and project impacts of both land use and climate change on continental-scale patterns in vector-borne diseases. Models were developed for cutaneous and visceral leishmaniasis in the Americas-ecologically complex sand fly borne infections linked to tropical forests and diverse wild and domestic mammal hosts. Both diseases were hypothesised to increase with available interface habitat between forest and agricultural or domestic habitats and with mammal biodiversity. However, landscape edge metrics were not important as predictors of leishmaniasis. Models including mammal richness were similar in accuracy and predicted disease extent to models containing only climate and land use predictors. Overall, climatic factors explained 80% and land use factors only 20% of the variance in past disease patterns. Both diseases, but especially cutaneous leishmaniasis, were associated with low seasonality in temperature and precipitation. Since such seasonality increases under future climate change, particularly under strong climate forcing, both diseases were predicted to contract in geographical extent to 2050, with cutaneous leishmaniasis contracting by between 35% and 50%. Whilst visceral leishmaniasis contracted slightly more under strong than weak management for carbon, biodiversity and ecosystem services, future cutaneous leishmaniasis extent was relatively insensitive to future

  5. Assessment of the mitigation options in the energy system in Bulgaria

    Christov, C.; Vassilev, C.; Simenova, K. [and others

    1996-12-31

    Bulgaria signed the Framework Convention on Climate Change at the UNCEP in Rio in June 1992. The parliament ratified the Convention in March 1995. In compliance with the commitments arising under the Convention, Bulgaria elaborates climate change polity. The underlying principles in this policy are Bulgaria to joint the international efforts towards solving climate change problems to the extent that is adequate to both the possibilities of national economy and the options to attract foreign investments. All policies and measures implemented should be as cost-effective as possible. The Bulgarian GHG emission profile reveals the energy sector as the most significant emission source and also as an area where the great potential for GHG emissions reduction exists. This potential could be achieved in many cases by relatively low cost or even no-cost options. Mitigation analysis incorporates options in energy demand and energy supply within the period 1992-2020.

  6. The climate impact of travel behavior: A German case study with illustrative mitigation options

    Aamaas, Borgar; Borken-Kleefeld, Jens; Peters, Glen P.

    2013-01-01

    Highlights: • We estimate the climate impact of German travel behavior. • The climate impact is equally dominated by car and air transport. • The rich have the largest impacts, but the larger middle class has a greater share. • A few long trips by air are responsible for a large share of the total climate impact. • A comprehensive mitigation is needed covering technology and behavioral changes. -- Abstract: Global greenhouse gas mitigation should include the growing share of emissions from transportation. To help understand the mitigation potential of changing travel behavior requires disaggregating the climate impacts of transportation by transport mode, distance, and travel behavior. Here we use disaggregated data on travel behavior to calculate the climate impact of Germans traveling nationally and internationally in 2008 and develop some illustrative mitigation options. We include all relevant long-lived greenhouse gases and short-lived climate forcers and use global temperature change for 50 years of sustained emissions as the emission metric. The total climate impact is determined almost entirely by car (∼46%) and air travel (∼45%), with smaller contributions from public transportation. The climate impact from the highest income group is 250% larger than from the lowest income group. However, the middle classes account for more than two thirds of the total impact. The relatively few trips beyond 100 km contribute more than half of the total impact because of the trip distance and use of aircraft. Individual behavioral changes, like shifting transport modes or reducing distance and frequency, can lead to useful emission reductions. However, a comprehensive package of mitigation options is necessary for deep and sustained emission reductions

    The South African Country Study Programme is being executed under the auspices of the South African Department of Environmental Affairs and Tourism (DEAandT). The full study comprises the following four components, each headed by a technical coordinator: the 1990 greenhouse gas emissions inventory; a study of South Africa`s vulnerability to climate change and possible adaptation strategies; potential mitigation actions and; policy development. Ideally, these components should be executed in sequence. However, in view of South Africa`s commitments in terms of the Framework Convention on Climate Change (FCCC) and the need to draw up a national communication, it was decided to execute the components simultaneously, with an emphasis on coordination between the components.

  9. Mitigation options for fish kills in L Lake and Pond C

    Paller, M.H.

    1989-11-01

    This report concerns mitigation options for reducing or eliminating the fish kills that occur in L Lake and Pond C as a result of reactor operations. These kills occur when fish that have entered the discharge areas during outages are killed by the rapid rises in temperature that follow reactor re-starts. Factors that have been observed to influence the severity of the kills include the length of the outage, season during which the outage occurs, reactor power level, and size of the fish in the discharge area. Without mitigation, fish kills can be expected to occur in Pond C with approximately the same frequency and severity as in the past. Even in the absence of mitigation, however, it is unlikely that future fish kills in L Lake will be as severe as the large kill that occurred in December 1986. Fish abundance in Region 2 of L Lake (where severe kills occurred in the past) has declined over 90% since 1986, largely due to a reduction in the abundance of juvenile sunfish (which constituted approximately 99% of past kills). There are basically three categories of mitigation options: changes in reactor operations, methods to exclude fish from time discharge areas, and methods to promote the escapement of fish from the discharge area. These options vary in approach, scope, and anticipated expense. Most would need to be researched in greater depth before it would be possible to predict their effectiveness more definitively. While the options have the potential to greatly reduce mortalities, none can totally eliminate mortalities. The only way of ensuring the elimination of all mortalities is to reduce effluent temperatures to sublethal levels with properly designed and operated cooling technology. 18 refs., 2 figs., 1 tab

  10. Mitigation options : flare and vent mitigation undercuts CCS in trimming CO{sub 2} emissions

    Smith, M.

    2010-11-15

    This article reported on a study aimed at reducing flaring and venting associated with conventional heavy oil production. In particular, the study analyzed parameters such as the variability in flare volumes, flare gas composition and statistical distribution of volumes flared. The objective was to determine the most viable economic solution to reducing flare and vent volumes. In particular, the study focused on various scenarios to tie-in currently flared and vented solution gas. Solution gas volume variability was found to be wide ranging, with 90 percent of sites handling less than 32 percent of the volume and 10 percent of the sites handling more than two-thirds of the volume. Composition also varied, and was difficult to measure. One scenario assumed that wells were unconnected and had to be tied in with their own compressors and pipe, while another scenario considered the wells to be individual wells. A first comprehensive analysis of flare and vent mitigation opportunities in Alberta revealed that tying in solution gas at battery sites could create emissions reductions at much lower cost than the province's carbon capture and storage (CCS) plan. The study of mitigation options primarily targeted the conventional heavy oil belt of eastern Alberta near Lloydminster. The most optimistic scenario included a $15 per tonne carbon credit, that up to 55 megatonnes could be trimmed over 10 years at no cost to the industry.1 fig.

  11. General equilibrium effects of a supply side GHG mitigation option under the Clean Development Mechanism.

    Timilsina, Govinda R; Shrestha, Ram M

    2006-09-01

    The Clean Development Mechanism (CDM) under the Kyoto Protocol to the United Nations Framework Convention on Climate Change is considered a key instrument to encourage developing countries' participation in the mitigation of global climate change. Reduction of greenhouse gas (GHG) emissions through the energy supply and demand side activities are the main options to be implemented under the CDM. This paper analyses the general equilibrium effects of a supply side GHG mitigation option-the substitution of thermal power with hydropower--in Thailand under the CDM. A static multi-sector general equilibrium model has been developed for the purpose of this study. The key finding of the study is that the substitution of electricity generation from thermal power plants with that from hydropower plants would increase economic welfare in Thailand. The supply side option would, however, adversely affect the gross domestic product (GDP) and the trade balance. The percentage changes in economic welfare, GDP and trade balance increase with the level of substitution and the price of certified emission reduction (CER) units.

  13. Biomass energy development and carbon dioxide mitigation options

    Hall, D.O.; House, J.I.

    1995-01-01

    Studies on climate change and energy production increasingly recognize the crucial role of biological systems. Carbon sinks in forests (above and below ground), CO 2 emissions from deforestation, planting trees for carbon storage, and biomass as a substitute for fossil fuels are some of the key issues which arise. Halting deforestation is of paramount importance, but there is also great potential for reforestation of degraded lands, agroforestry and improved forest management. We conclude that biomass energy plantations and other types of energy cropping could be a more effective strategy for carbon mitigation than simply growing trees as a carbon store. Using the biomass for production of modern energy carriers such as electricity, and liquid and gaseous fuels also has a wide range of other environmental, social and economic benefits. In order for biomass projects to succeed, it is necessary to ensure that these benefits are felt locally as well as nationally, furthermore, environmental sustainability of bioenergy projects is an essential requirement. The constraints to achieving environmentally-acceptable biomass production are not insurmountable. Rather they should be seen as scientific and entrepreneurial opportunities which will yield numerous advantages at local, national and international levels in the long term. (au) 76 refs

  14. Is carbon farming an effective climate mitigation option?

    Zelikova, T. J.; Funk, J.; Deich, N.; Amador, G.; Jacobson, R.

    2017-12-01

    "Carbon farming" refers to agricultural and land management practices that store carbon in soils and biomass. Carbon-farming techniques can include crop rotation, cover crops, no-till practices, and the application of compost to build up soil organic matter. Carbon farming also improves agricultural production and sustainability, while mitigating climate change. Despite well-documented benefits of carbon farming, these practices continue to be underutilized outside of experimental settings. One barrier to the widespread use of carbon farming is the challenge of fitting these practices into ongoing commercial operations, while managing the consequent market uncertainties across the value chain. To help address this barrier, we are working with landowners and local groups to establish demonstration "test beds" that can build experience among land managers and help resolve market uncertainties. We specifically focus on demonstrating the commercial viability of management practices that can enhance soil health, catalyzing economic and environmental synergies that come from healthy soils. Each test bed has a commercial agricultural operation at its center, and we bring together researchers, local groups, corporate partners, and key policymakers who can support wider adoption of these agricultural techniques. Early challenges have included finding commercial farms willing to shift their practices and face uncertain outcomes. A transition to new practices usually involves changes in equipment, scheduling, activities, and monitoring that have implications for the entire farm operation, its resources, and its bottom line. At the same time, practitioners have difficulty quantifying the carbon benefits they provide, due to persistent uncertainties, even with the benefit of decades of experimental research. We are building a network of farmers who are implementing carbon farming practices and addressing these challenges, step by step. We envision our test beds becoming hubs

  15. Sensitivity of Space Launch System Buffet Forcing Functions to Buffet Mitigation Options

    Piatak, David J.; Sekula, Martin K.; Rausch, Russ D.

    2016-01-01

    Time-varying buffet forcing functions arise from unsteady aerodynamic pressures and are one of many load environments, which contribute to the overall loading condition of a launch vehicle during ascent through the atmosphere. The buffet environment is typically highest at transonic conditions and can excite the vehicle dynamic modes of vibration. The vehicle response to these buffet forcing functions may cause high structural bending moments and vibratory environments, which can exceed the capabilities of the structure, or of vehicle components such as payloads and avionics. Vehicle configurations, protuberances, payload fairings, and large changes in stage diameter can trigger undesirable buffet environments. The Space Launch System (SLS) multi-body configuration and its structural dynamic characteristics presented challenges to the load cycle design process with respect to buffet-induced loads and responses. An initial wind-tunnel test of a 3-percent scale SLS rigid buffet model was conducted in 2012 and revealed high buffet environments behind the booster forward attachment protuberance, which contributed to reduced vehicle structural margins. Six buffet mitigation options were explored to alleviate the high buffet environments including modified booster nose cones and fences/strakes on the booster and core. These studies led to a second buffet test program that was conducted in 2014 to assess the ability of the buffet mitigation options to reduce buffet environments on the vehicle. This paper will present comparisons of buffet forcing functions from each of the buffet mitigation options tested, with a focus on sectional forcing function rms levels within regions of the vehicle prone to high buffet environments.

  17. Salt as a mitigation option for decreasing nitrogen leaching losses from grazed pastures.

    Ledgard, Stewart F; Welten, Brendon; Betteridge, Keith

    2015-12-01

    The main source of nitrogen (N) leaching from grazed pastures is animal urine with a high N deposition rate (i.e. per urine patch), particularly between late summer and early winter. Salt is a potential mitigation option as a diuretic to induce greater drinking-water intake, increase urination frequency, decrease urine N concentration and urine N deposition rate, and thereby potentially decrease N leaching. This hypothesis was tested in three phases: a cattle metabolism stall study to examine effects of salt supplementation rate on water consumption, urination frequency and urine N concentration; a grazing trial to assess effects of salt (150 g per heifer per day) on urination frequency; and a lysimeter study on effects of urine N rate on N leaching. Salt supplementation increased cattle water intake. Urination frequency increased by up to 69%, with a similar decrease in urine N deposition rate and no change in individual urination volume. Under field grazing, sensors showed increased urination frequency by 17%. Lysimeter studies showed a proportionally greater decrease in N leaching with decreased urine N rate. Modelling revealed that this could decrease per-hectare N leaching by 10-22%. Salt supplementation increases cattle water intake and urination frequency, resulting in a lower urine N deposition rate and proportionally greater decrease in urine N leaching. Strategic salt supplementation in autumn/early winter with feed is a practical mitigation option to decrease N leaching in grazed pastures. © 2015 Society of Chemical Industry.

    Climate change has become a global issue. Almost all countries, including China, are now considering adopting policies and measures to reduce greenhouse gas (GHG) emissions. The power generation sector, as a key source of GHG emissions, will also have significant potential for GHG mitigation. One of the key options is to use new energy technologies with higher energy efficiencies and lower carbon emissions. In this article, we use an energy technology model, MESSAGE-China, to analyze the trend of key new power generation technologies and their contributions to GHG mitigation in China. We expect that the traditional renewable technologies, high-efficiency coal power generation and nuclear power will contribute substantially to GHG mitigation in the short term, and that solar power, biomass energy and carbon capture and storage (CCS) will become more important in the middle and long term. In the meantime, in order to fully bring the role of technology progress into play, China needs to enhance the transfer and absorption of international advanced technologies and independently strengthen her ability in research, demonstration and application of new power generation technologies.

  3. Energy-saving options for the mitigation of greenhouse gas emissions from the Mongolian energy sector

    Dorjpurev, J.; Purevjal, O.; Erdenechimeg, Ch. [and others

    1996-12-31

    The Energy sector is the largest contributor to GHG emission in Mongolia. The Energy sector emits 54 percent of CO2 and 4 percent of methane. All emissions of other greenhouse gases are accounted from energy related activities. The activities in this sector include coal production, fuel combustion, and biomass combustion at the thermal power stations and in private houses (stoves) for heating purposes. This paper presents some important Demand-side options considered for mitigation of CO2 emissions from energy sector such as Energy Conservation in Industrial Sector and in Buildings. Changes in energy policies and programmes in the Mongolian situation that promote more efficient and sustainable practices are presented in the paper. These energy saving measures will not only help reduce greenhouse gas emissions, but will also promote economic development and alleviate other environmental problems.

  4. A New Strategy for Mitigating Climate Change

    Kaya, Y.; Akimoto, K./ Oda, J.

    2007-07-01

    This paper proposes a new strategy for mitigating climate change, both in short term and in long term. The basic character of the strategy is action oriented with multi-country collaboration, while the Framework Convention on Climate Change (FCCC) and Kyoto protocol is numerical target oriented within United Nation Framework. The introductory part of the paper briefly describes deficits of FCCC and Kyoto protocol and the needs of a different strategy for mitigating climate change. Then the short term strategy is focused on energy conservation and its effectiveness for mitigating climate change is illustrated by estimating the potential of reducing CO{sub 2} emission when intense collaboration is achieved for distributing main energy conservation measures in power generation and key industries among Asia Pacific Partnership countries. The long term strategy is developing novel types of renewables among countries. Geoheat and space solar power systems (SSPS) are candidates which may be developed among major developed countries. Necessity of international collaboration is stressed for R and D of these candidate renewables. (auth)

  5. Leapfrogging over development? Promoting rural renewables for climate change mitigation

    Renewable energy technologies have the potential to help solve two pressing problems. On one hand, carbon-free energy sources must play a role in climate change mitigation. On the other hand, renewables might help meet needs of rural people without access to modern energy services. However, if renewables are deployed to combat climate change (primarily resulting from emissions in the developed economies) then providing basic energy services in the developing world may be compromised. The tendency to conflate the two drivers by installing renewables in rural areas for carbon mitigation reasons rather than for development reasons could compromise both goals. The danger is supporting sub-optimal policies for mitigating carbon and for rural energy. This is problematic given the limited funds available for energy development and reducing greenhouse gases. This paper analyzes how these goals have been balanced by the Global Environment Facility (GEF). Project documents are used to determine whether incremental costs of installing renewables were covered by GEF funds and whether the costs are comparable with other carbon mitigation options. The results raise concerns about the effectiveness and appropriateness of GEF funding of such projects and highlight the importance of post-Kyoto framework design to reduce emissions and promote development.

  7. A Scheme for the Integrated Assessment of Mitigation Options

    Held, H.; Edenhofer, O.

    2003-04-01

    After some consensus has been achieved that the global mean temperature will have increased by 1.4 to 5.8^oC at the end of this century in case of continued ``business as usual'' greenhouse gas emissions, society has to decide if or which mitigation measures should be taken. A new integrated assessment project on this very issue will be started at PIK in spring 2003. The assessment will cover economic aspects as well as potential side effects of various measures. In the economic module, the effects of investment decisions on technological innovation will be explicitly taken into account. Special emphasize will be put on the issue of uncertainty. Hereby we distinguish the uncertainty related to the Integrated Assessment modules, including the economic module, from the fact that no over-complex system can be fully captured by a model. Therefore, a scheme for the assessment of the ``residual'', the non-modelled part of the system, needs to be worked out. The scheme must be truly interdisciplinary, i.e. must be applicable to at least the natural science and the economic aspects. A scheme based on meta-principles like minimum persistence, ubiquity, or irreversibility of potential measures appears to be a promising candidate. An implementation of ubiquity as at present successfully operated in environmental chemistry may serve as a guideline [1]. Here, the best-known mechanism within a complex impact chain of potentially harmful chemicals, their transport, is captured by a reaction-diffusion mechanism [2]. begin{thebibliography}{0} bibitem{s} M.

  8. Greenhouse gas emissions from Thailand’s transport sector: Trends and mitigation options

    Pongthanaisawan, Jakapong; Sorapipatana, Chumnong

    2013-01-01

    Rapid growth of population and economy during the past two decades has resulted in continuing growth of transport’s oil demand and greenhouse gas (GHG) emissions. The objectives of this study are to examine pattern and growth in energy demand as well as related GHG emissions from the transport sector and to analyze potential pathways of energy demand and GHG emissions reduction from this sector of the measures being set by the Thai Government. A set of econometric models has been developed to estimate the historical trend of energy demand and GHG emissions in the transport sector during 1989–2007 and to forecast future trends to 2030. Two mitigation option scenarios of fuel switching and energy efficiency options have been designed to analyze pathways of energy consumption and GHG emissions reduction potential in Thailand’s transport sector compared with the baseline business-as-usual (BAU) scenario, which assumed to do nothing influences the long-term trends of transport energy demand. It has been found that these two mitigation options can reduce the GHG emissions differently. The fuel-switching option could significantly reduce the amount of GHG emissions in a relatively short time frame, albeit it will be limited by its supply resources, whereas the energy efficiency option is more effective for GHG emissions mitigation in the long term. Therefore, both measures should be implemented simultaneously for both short and long term mitigation effects in order to more effectively achieve GHG emissions reduction target.

  9. Climate change mitigation through livestock system transitions

    Livestock are responsible for 12% of anthropogenic greenhouse gas emissions. Sustainable intensification of livestock production systems might become a key climate mitigation technology. However, livestock production systems vary substantially, making the implementation of climate mitigation policies a formidable challenge. Here, we provide results from an economic model using a detailed and high-resolution representation of livestock production systems. We project that by 2030 autonomous transitions toward more efficient systems would decrease emissions by 736 million metric tons of carbon dioxide equivalent per year (MtCO2e⋅y−1), mainly through avoided emissions from the conversion of 162 Mha of natural land. A moderate mitigation policy targeting emissions from both the agricultural and land-use change sectors with a carbon price of US$10 per tCO2e could lead to an abatement of 3,223 MtCO2e⋅y−1. Livestock system transitions would contribute 21% of the total abatement, intra- and interregional relocation of livestock production another 40%, and all other mechanisms would add 39%. A comparable abatement of 3,068 MtCO2e⋅y−1 could be achieved also with a policy targeting only emissions from land-use change. Stringent climate policies might lead to reductions in food availability of up to 200 kcal per capita per day globally. We find that mitigation policies targeting emissions from land-use change are 5 to 10 times more efficient—measured in “total abatement calorie cost”—than policies targeting emissions from livestock only. Thus, fostering transitions toward more productive livestock production systems in combination with climate policies targeting the land-use change appears to be the most efficient lever to deliver desirable climate and food availability outcomes.

  10. Greenhouse gas mitigation options in the forestry sector of The Gambia: Analysis based on COMAP model

    Jallow, B.P.

    1996-12-31

    Results of the 1993 Greenhouse Gas Emissions Inventory of The Gambia showed net CO{sub 2} emissions of over (1.66 x 10{sup 6} tons) and 1% was due to uptake by plantations (0.01 x 10{sup 6} tons). This is a clear indication that there is need to identify changes in the land-use policy, law and tenure that discourages forest clearing at the same time significantly influencing the sustainable distribution of land among forestry, rangeland and livestock, and agriculture. About 11% of the total area of The Gambia is either fallow or barren flats that once supported vegetation and hence is still capable of supporting vegetation. The US Country Study Programme has provided the Government of The Gambia through the National Climate Committee funds to conduct Assessment of Mitigation Options to Reduce Greenhouse Gas Emissions. The Forestry Sector is one area for which assessment is being conducted. The assessment is expected to end in September 1996. The Comprehensive Mitigation Analysis Process (COMAP) is one of the Models supplied to the National Climate Committee by the Lawrence Berkeley Laboratory, on behalf of the US Country Study Programme, and is being used to conduct the analysis in The Gambia.

  11. Carbon flows and economic evaluation of mitigation options in Tanzania's forest sector

    Makundi, W.; Okiting'ati, Aku

    1995-01-01

    This paper presents estimates of the rate of forest use, deforestation and forest degradation, as well as the corresponding carbon flows, in the Tanzanian forest sector. It is estimated that the country lost 525,000 ha of forests in 1990, with associated committed emissions of 31.5 Mt carbon (MtC), and 7.05 MtC of committed carbon sequestration. The paper then describes the possible response options in the forest sector to mitigate GHG emissions, and evaluates the most stable subset of these - i.e. forest conservation, woodfuel plantations and agroforestry. The conservation options were found to cost an average of US$1.27 per tonne of carbon (tC) conserved. Five options for fuelwood plantations and agroforestry, with two different ownership regimes were evaluated. Each one of the options gives a positive net present value at low rates of discount, ranging from U.S.$1.06 to 3.4/tC of avoided emissions at 0% discount rate. At 10% discount, the eucalyptus and maize option has a highest PNV of U.S.$1.73/tC, and the government plantation gives a negative PNV (loss) of U.S.$ 0.13 tC sequestered. The options with a private/community type of ownership scheme fared better than government run options. This conclusion also held true when ranking the options by the BRAC indicator, with the government fuelwood plantation ranked the lowest, and the private agroforestry option of eucalyptus and corn performing best. The mitigation options evaluated here show that the forest sector in Tanzania has one of the most cost-effective GHG mitigation opportunities in the world, and they are within the development aspirations of the country.

  12. EUROPEAN UNION POLICIES FOR CLIMATE CHANGE MITIGATION

    Paul Canter

    2017-07-01

    Full Text Available Climate change is one of the most important challenges that humanity faces in the 21st century, and for the European Union, combating this phenomenon represents an important element, which is reflected both in the actions carried out in recent years, domestically and internationally, as well as in the EU policy on climate change. Within the EU, regulations were adopted, that demonstrate the importance that the Union confers to the limitation of this phenomenon, stressing at the same time the need for an integrated policy framework to ensure the security for potential investors and a coordinated approach between Member States. This paper will present recent developments for the most important policies to combat and mitigate climate change in the European Union, starting with "20-20-20" objectives, which are to be met through the package "Energy-Climate Change", continuing with 2030 and 2050 timeframes, and finally presenting the main lines of action to combat climate change.

  13. Mitigating climate change: The Philippine case

    Garcia, J.L.L.

    1998-01-01

    The Government of the Philippines signed the UN Framework Convention on Climate change on June 12, 1992 and the Philippine Congress ratified it in 1994. The Philippine Government has also subsequently created the Inter-Agency Committee on Climate Change (IACCC). The GOP is currently preparing the Philippine Country Study to address climate change. The first phase of the work was financed by a grant from the US Country Studies Program which is led by the US Department of Energy. The Study includes the following elements: a) development of a National Inventory of GHG emission and Sinks; b) vulnerability assessment and evaluation of adaptations of coastal resources; c) identification of alternative programs and measures to promote mitigation and/or adaptation to climate change; d) public information and education campaign; and e) development of the National Action Plan on Climate Change.

  15. Assessing CO2 Mitigation Options Utilizing Detailed Electricity Characteristics and Including Renewable Generation

    Bensaida, K.; Alie, Colin; Elkamel, A.; Almansoori, A.

    2017-08-01

    This paper presents a novel techno-economic optimization model for assessing the effectiveness of CO2 mitigation options for the electricity generation sub-sector that includes renewable energy generation. The optimization problem was formulated as a MINLP model using the GAMS modeling system. The model seeks the minimization of the power generation costs under CO2 emission constraints by dispatching power from low CO2 emission-intensity units. The model considers the detailed operation of the electricity system to effectively assess the performance of GHG mitigation strategies and integrates load balancing, carbon capture and carbon taxes as methods for reducing CO2 emissions. Two case studies are discussed to analyze the benefits and challenges of the CO2 reduction methods in the electricity system. The proposed mitigations options would not only benefit the environment, but they will as well improve the marginal cost of producing energy which represents an advantage for stakeholders.

  16. Exploring the options for carbon dioxide mitigation in Turkish electric power industry: System dynamics approach

    Saysel, Ali Kerem; Hekimoğlu, Mustafa

    2013-01-01

    Electric power industry has a huge carbon mitigation potential, fundamentally because there are large carbon-free, renewable resource options. In Turkey, with growing demand in electricity consumption and incentives offered for natural gas fired electricity generation, CO 2 emissions sourced from electric power industry had tripled over the last two decades. Current governmental strategy focuses on energy security and resource diversity in a growing economy and does not articulate sufficient mitigation targets and appropriate regulations. In this research, an original dynamic simulation model is built, validated and analyzed to explore the options for carbon mitigation in Turkish electric power industry. Model structure represents the investment, dispatch and pricing heuristics as well as the natural resource base of electricity generation in Turkey. It operates on annual basis over 30 years to simulate installed capacities and generations of power plants with alternative resources and their resulting CO 2 emissions. The analysis presented in this paper reveals that there are mitigation options below 50% of business as usual growth, with common policy options such as feed-in-tariffs, investment subsidies and carbon taxes. The model can serve as an experimental platform for further analysis of problems related to carbon mitigation in Turkish electricity sector. - Highlights: • An original computer model is created to investigate carbon mitigation. • It is holistic and comprises investment, generation, dispatch, and resources. • The model's structure, information base and foresights are specific to Turkey. • Direct and indirect strategies are explored and integrated. • Dramatic reductions are possible only with supply side strategies

  17. Integrating uncertainties for climate change mitigation

    2013-04-01

    The target of keeping global average temperature increase to below 2°C has emerged in the international climate debate more than a decade ago. In response, the scientific community has tried to estimate the costs of reaching such a target through modelling and scenario analysis. Producing such estimates remains a challenge, particularly because of relatively well-known, but ill-quantified uncertainties, and owing to limited integration of scientific knowledge across disciplines. The integrated assessment community, on one side, has extensively assessed the influence of technological and socio-economic uncertainties on low-carbon scenarios and associated costs. The climate modelling community, on the other side, has worked on achieving an increasingly better understanding of the geophysical response of the Earth system to emissions of greenhouse gases (GHG). This geophysical response remains a key uncertainty for the cost of mitigation scenarios but has only been integrated with assessments of other uncertainties in a rudimentary manner, i.e., for equilibrium conditions. To bridge this gap between the two research communities, we generate distributions of the costs associated with limiting transient global temperature increase to below specific temperature limits, taking into account uncertainties in multiple dimensions: geophysical, technological, social and political. In other words, uncertainties resulting from our incomplete knowledge about how the climate system precisely reacts to GHG emissions (geophysical uncertainties), about how society will develop (social uncertainties and choices), which technologies will be available (technological uncertainty and choices), when we choose to start acting globally on climate change (political choices), and how much money we are or are not willing to spend to achieve climate change mitigation. We find that political choices that delay mitigation have the largest effect on the cost-risk distribution, followed by

  18. Storm surges-An option for Hamburg, Germany, to mitigate expected future aggravation of risk

    Storch, Hans von; Goennert, Gabriele; Meine, Manfred

    2008-01-01

    Summary: Rising sea level together with regionally increased storm activity, caused by elevated and increasing levels of greenhouse gases in the atmosphere will in many parts of the world increase the risk of storm surges significantly. Reducing the emissions of greenhouse gases into the atmosphere may mitigate the increasing risks somewhat, but the major task for regional and local stakeholders will be to prepare for appropriate adaptation. In most cases, possible strategies include intensification of coastal defense measures, in particular strengthening dykes, and adaptation to intermittent flooding. In case of Hamburg and the tidal Elbe river a third option seems to be available, which aims at mitigating storm surge risks by applying estuary engineering constructions. This option is sketched in this paper. The option has the potential to significantly reduce the expected future increases of local surge heights

    Traditional charcoal production, firewood sourcing and over-dependence on the national grid for electricity are associated with high greenhouse gas emissions relative to other common energy options. However, there have been few attempts to analyze the potential of cogeneration and briquetting as favourable energy options for climate change mitigation. The possibility of utilizing abundant wood residues to produce energy for domestic and industrial application through co-generation and sawdust briquetting was assessed. Annual residues generated in the three mills studied ranged from 19,230 m3 to 32,610 m3. Annual output of semi-carbonized and carbonized sawdust briquette from the briquette factory studied was 1400 tonnes. Heating values of the wood species ranged from 8.2 to 20.3 MJ/kg. Power requirements for the mills, necessary for sizing co-generation units were derived from their monthly electricity bills. Power ratings for co-generation units were specified between 400 kWe to 2000 kWe with heat to power ratios of 19 to 21. The energy generated could be used to produce electrical power and reduce dependency on the national grid. Conversion of sawdust in the briquette factory potentially contributes a saving of 5,600 tonnes of trees/year that would have been cut from the forest. Thus, adoption of co-generation and sawdust briquetting nationwide could be of immense benefit to the country in terms of climate change mitigation.

  20. Mitigating Climate Change with Earth Orbital Sunshades

    Coverstone, Victoria; Johnson, Les

    2015-01-01

    An array of rotating sunshades based on emerging solar sail technology will be deployed in a novel Earth orbit to provide near-continuous partial shading of the Earth, reducing the heat input to the atmosphere by blocking a small percentage of the incoming sunlight, and mitigating local weather effects of anticipated climate change over the next century. The technology will provide local cooling relief during extreme heat events (and heating relief during extreme cold events) thereby saving human lives, agriculture, livestock, water and energy needs. A synthesis of the solar sail design, the sails' operational modes, and the selected orbit combine to provide local weather modification.

  1. Asia least-cost greenhouse gas abatement strategy identification and assessment of mitigation options for the energy sector

    Gupta, Sujata; Bhandari, Preety

    1998-01-01

    The focus of the presentation was on greenhouse gas mitigation options for the energy sector for India. Results from the Asia Least-cost Greenhouse gas Abatement Strategies (ALGAS) project were presented. The presentation comprised of a review of the sources of greenhouse gases, the optimisation model, ie the Markal model, used for determining the least-cost options, discussion of the results from the baseline and the abatement scenarios. The second half of the presentation focussed on a multi-criteria assessment of the abatement options using the Analytical Hierarchical Process (AHP) model. The emissions of all greenhouse gases, for India, are estimated to be 986.3 Tg of carbon dioxide equivalent for 1990. The energy sector accounted for 58 percent of the total emissions and over 90 percent of the CO2 emissions. Net emissions form land use change and forestry were zero. (au)

The TNA process involves different stakeholders in a consultative process, enabling all stakeholders to understand their technology needs in a cohesive manner, and prepare Technology Action Plans (TAPs) accordingly. The TNA project is funded by the Global Environment Facility (GEF) and is being implemented by UNEP and the URC in 36 developing countries. (Author)

  3. Forest Biomass for Climate Change Mitigation

    Nielsen, Anders Tærø

    Awareness of elevated CO2 levels in the atmosphere and resulting climate change has increased focus on renewable energy sources during recent decades. Biomass for energy has been predicted to have the greatest potential for CO2 reductions in the short term and the IPCC assumes that the use...... of biomass for energy is CO2 neutral. Several studies have however criticized this CO2 neutrality assumption and questioned whether CO2 reductions actually are achieved through use of biomass for energy. The purpose of this thesis is to investigate the biomass production potential of poplar plantations...... on southern Scandinavian sites, managed under different systems both in agriculture and in forests. In addition, the objective is to assess the potential of the poplar plantations to mitigate climate change by using poplar biomass for substitution of fossil fuels in comparison to a traditional product...

  4. Voluntary climate change mitigation actions of young adults: a classification of mitigators through latent class analysis.

    Korkala, Essi A E; Hugg, Timo T; Jaakkola, Jouni J K

    2014-01-01

    Encouraging individuals to take action is important for the overall success of climate change mitigation. Campaigns promoting climate change mitigation could address particular groups of the population on the basis of what kind of mitigation actions the group is already taking. To increase the knowledge of such groups performing similar mitigation actions we conducted a population-based cross-sectional study in Finland. The study population comprised 1623 young adults who returned a self-administered questionnaire (response rate 64%). Our aims were to identify groups of people engaged in similar climate change mitigation actions and to study the gender differences in the grouping. We also determined if socio-demographic characteristics can predict group membership. We performed latent class analysis using 14 mitigation actions as manifest variables. Three classes were identified among men: the Inactive (26%), the Semi-active (63%) and the Active (11%) and two classes among women: the Semi-active (72%) and the Active (28%). The Active among both genders were likely to have mitigated climate change through several actions, such as recycling, using environmentally friendly products, preferring public transport, and conserving energy. The Semi-Active had most probably recycled and preferred public transport because of climate change. The Inactive, a class identified among men only, had very probably done nothing to mitigate climate change. Among males, being single or divorced predicted little involvement in climate change mitigation. Among females, those without tertiary degree and those with annual income €≥16801 were less involved in climate change mitigation. Our results illustrate to what extent young adults are engaged in climate change mitigation, which factors predict little involvement in mitigation and give insight to which segments of the public could be the audiences of targeted mitigation campaigns.

  6. Strategies for implementation of CO2-mitigation options in Nigeria's energy sector

    Ibitoye, F.I.; Akinbami, J.-F.K.

    1999-01-01

    Recent studies indicate that Nigeria's CO 2 budget was about 164 million tonnes (MTons) in 1990, of which the energy sector contributed close to 55%. It is expected that CO 2 emissions emanating from the energy sector will increase from 90 MTons in 1990 to about 3 times this value in another 30 years, assuming a least-cost moderate development scenario. A number of viable CO 2 -mitigation options have already been identified in the energy sector, some of them the so-called 'win-win' options. As attractive as some of these options might appear, their implementation will depend on the removal of certain barriers. These barriers include a lack of legislative framework, a lack of awareness, a lack of access to appropriate technology, as well as inappropriate energy-pricing policies, among others. The paper presents an overview of Nigeria's energy-sector, the CO 2 mitigation-options, the factors militating against implementation of the options, and some policy recommendations for removal of the barriers.

  7. Integrated economic assessment of energy and forestry mitigation options using MARKAL

    1998-01-01

    There have been a number of economic assessment of GHG mitigation studies carried out in Indonesia. Several alternative mitigation options for energy and non-energy sectors have been described and the economic assessment of the options has been done for each sectors. However, most of the economic assessment particularly for non-energy sector, was not to find a least cost option but the lowest cost options. A program called MARKAL developed by a consortium of energy specialists from more than a dozen countries in the early 1980s, is a program that can be used for optimization, so that the least cost options could be selected. Indonesia has used this program intensively for energy system analysis. Attempt to use this program for other sector has not been developed as this program was designed for energy sector. Therefore, using MARKAL for other sector, all activities of the other sectors should be treated as energy activities. This study is aimed to use MARKAL for analysing both energy and forestry sector together. This paper described briefly the methodology of using MARKAL for both energy and forestry sectors. As the activities in energy sector have unique characteristics, thus only forest activities are described in more detail. (au)

    Lake Victoria is an international waterbody that offers the riparian communities a large number of extremely important environmental services. Over the past three decades or so, the lake has come under increasing and considerable pressure from a variety of interlinked human activities such as overfishing, species introductions, industrial pollution, eutrophication, and sedimentation. In this paper we examine the root causes for overfishing and pollution in Lake Victoria and give possible policy options that can help remediate or mitigate the environmental degradation.

  10. National action to mitigate global climate change

    1995-06-01

    Over 170 participants from 60 countries met for three days in Copenhagen from 7 to 9 June 1994 to discuss howe the aims of the United Nations Framework convention on Climate Change can be translated into practical action. The Conference was organised by the UNEP collaborating Centre on Energy and Environment (UCCEE), with financial support from the Danish International Development Agency (Danida), the Global Environment Facility (GEF), the United Nations Environment Programme (UNEP) and Risoe National Laboratory, Denmark. The main objective of the conference was to identify common approaches to national mitigation analysis for countries to use in meeting their commitments under the FCCC, and in setting priorities for national actions. Although addressing a broader theme, the conference marked the completion and publication of the second phase on UNEP Greenhouse Gas Abatement Costing Study. (au)

  11. Climate Change Mitigation A Balanced Approach to Climate Change

    2012-01-01

    This book provides a fresh and innovative perspective on climate change policy. By emphasizing the multiple facets of climate policy, from mitigation to adaptation, from technological innovation and diffusion to governance issues, it contains a comprehensive overview of the economic and policy dimensions of the climate problem. The keyword of the book is balance. The book clarifies that climate change cannot be controlled by sacrificing economic growth and many other urgent global issues. At the same time, action to control climate change cannot be delayed, even though gradually implemented. Therefore, on the one hand climate policy becomes pervasive and affects all dimensions of international policy. On the other hand, climate policy cannot be too ambitious: a balanced approach between mitigation and adaptation, between economic growth and resource management, between short term development efforts and long term innovation investments, should be adopted. I recommend its reading. Carlo Carraro, President, Ca�...

  12. Modelling mitigation options to reduce diffuse nitrogen water pollution from agriculture.

    Bouraoui, Fayçal; Grizzetti, Bruna

    2014-01-15

    Agriculture is responsible for large scale water quality degradation and is estimated to contribute around 55% of the nitrogen entering the European Seas. The key policy instrument for protecting inland, transitional and coastal water resources is the Water Framework Directive (WFD). Reducing nutrient losses from agriculture is crucial to the successful implementation of the WFD. There are several mitigation measures that can be implemented to reduce nitrogen losses from agricultural areas to surface and ground waters. For the selection of appropriate measures, models are useful for quantifying the expected impacts and the associated costs. In this article we review some of the models used in Europe to assess the effectiveness of nitrogen mitigation measures, ranging from fertilizer management to the construction of riparian areas and wetlands. We highlight how the complexity of models is correlated with the type of scenarios that can be tested, with conceptual models mostly used to evaluate the impact of reduced fertilizer application, and the physically-based models used to evaluate the timing and location of mitigation options and the response times. We underline the importance of considering the lag time between the implementation of measures and effects on water quality. Models can be effective tools for targeting mitigation measures (identifying critical areas and timing), for evaluating their cost effectiveness, for taking into consideration pollution swapping and considering potential trade-offs in contrasting environmental objectives. Models are also useful for involving stakeholders during the development of catchments mitigation plans, increasing their acceptability. © 2013.

  13. Economics of nuclear power and climate change mitigation policies.

    Bauer, Nico; Brecha, Robert J; Luderer, Gunnar

    2012-10-16

    The events of March 2011 at the nuclear power complex in Fukushima, Japan, raised questions about the safe operation of nuclear power plants, with early retirement of existing nuclear power plants being debated in the policy arena and considered by regulators. Also, the future of building new nuclear power plants is highly uncertain. Should nuclear power policies become more restrictive, one potential option for climate change mitigation will be less available. However, a systematic analysis of nuclear power policies, including early retirement, has been missing in the climate change mitigation literature. We apply an energy economy model framework to derive scenarios and analyze the interactions and tradeoffs between these two policy fields. Our results indicate that early retirement of nuclear power plants leads to discounted cumulative global GDP losses of 0.07% by 2020. If, in addition, new nuclear investments are excluded, total losses will double. The effect of climate policies imposed by an intertemporal carbon budget on incremental costs of policies restricting nuclear power use is small. However, climate policies have much larger impacts than policies restricting the use of nuclear power. The carbon budget leads to cumulative discounted near term reductions of global GDP of 0.64% until 2020. Intertemporal flexibility of the carbon budget approach enables higher near-term emissions as a result of increased power generation from natural gas to fill the emerging gap in electricity supply, while still remaining within the overall carbon budget. Demand reductions and efficiency improvements are the second major response strategy.

  15. IPCC Climate Change 2013: Mitigation of Climate Change - Key Findings and Lessons Learned

    Sokona, Youba

    2014-05-01

    The Working Group III contribution to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change, Mitigation of Climate Change, examines the results of scientific research about mitigation, with special attention on how knowledge has evolved since the Fourth Assessment Report published in 2007. Throughout, the focus is on the implications of its findings for policy, without being prescriptive about the particular policies that governments and other important participants in the policy process should adopt. The report begins with a framing of important concepts and methods that help to contextualize the findings presented throughout the assessment. The valuation of risks and uncertainties, ethical concepts and the context of sustainable development and equity are among the guiding principles for the assessment of mitigation strategies. The report highlights past trends in stocks and flows of greenhouse gases and the factors that drive emissions at global, regional, and sectoral scales including economic growth, technology or population changes. It provides analyses of the technological, economic and institutional requirements of long-term mitigation scenarios and details on mitigation measures and policies that are applied in different economic sectors and human settlements. It then discusses interactions of mitigation policies and different policy instrument types at national, regional and global governance levels and between economic sectors, The Working Group III report comprises 16 chapters and in assembling this assessment authors were guided by the principles of the IPCC mandate: to be explicit about mitigation options, to be explicit about their costs and about their risks and opportunities vis-à-vis other development priorities, and to be explicit about the underlying criteria, concepts, and methods for evaluating alternative policies.

  16. Climate change mitigation policies and poverty in developing countries

    Hussein, Zekarias; Hertel, Thomas; Golub, Alla

    2013-09-01

    Mitigation of the potential impacts of climate change is one of the leading policy concerns of the 21st century. However, there continues to be heated debate about the nature, the content and, most importantly, the impact of the policy actions needed to limit greenhouse gas emissions. One contributing factor is the lack of systematic evidence on the impact of mitigation policy on the welfare of the poor in developing countries. In this letter we consider two alternative policy scenarios, one in which only the Annex I countries take action, and the second in which the first policy is accompanied by a forest carbon sequestration policy in the non-Annex regions. Using an economic climate policy analysis framework, we assess the poverty impacts of the above policy scenarios on seven socio-economic groups in 14 developing countries. We find that the Annex-I-only policy is poverty friendly, since it enhances the competitiveness of non-Annex countries—particularly in agricultural production. However, once forest carbon sequestration incentives in the non-Annex regions are added to the policy package, the overall effect is to raise poverty in the majority of our sample countries. The reason for this outcome is that the dominant impacts of this policy are to raise returns to land, reduce agricultural output and raise food prices. Since poor households rely primarily on their own labor for income, and generally own little land, and since they also spend a large share of their income on food, they are generally hurt on both the earning and the spending fronts. This result is troubling, since forest carbon sequestration—particularly through avoided deforestation—is a promising, low cost option for climate change mitigation.

  19. Demand-side mitigation options of the agricultural sector: potential, barriers and ways forward

    Brunelle Thierry

    2017-01-01

    Full Text Available This paper reviews the potential and barriers of demand-side mitigation options in the agricultural sector based on the recent academic literature and on a survey conducted on a sample of 788 respondents living in France. The mitigation potential of such measures as reducing losses in the food supply chain and shifting diets toward less animal products is estimated to be particularly high, higher, in particular, than supply-side mitigation options. However, to ensure that these measures do not entail a reduction in protein intake, these estimations should consider both caloric and protein units, and take into account the digestibility differentials between protein sources. Our survey shows that people are relatively reluctant to eat more sustainably, preferring to reduce their emissions in other areas such as housing or equipment. This relative reluctance is mainly due to individual perceptions linked to health concerns, taste or habits. Some obstacles could easily be overcome through well-designed policies aiming to, for example, advertise a lower consumption of red meat for health benefits. National governments are, however, rather inactive on this topic, leaving the initiative to the civil society.

  20. Carbon sequestration to mitigate climate change

    Sundquist, Eric; Burruss, Robert; Faulkner, Stephen; Gleason, Robert; Harden, Jennifer; Kharaka, Yousif; Tieszen, Larry; Waldrop, Mark

    2008-01-01

    Human activities, especially the burning of fossil fuels such as coal, oil, and gas, have caused a substantial increase in the concentration of carbon dioxide (CO2) in the atmosphere. This increase in atmospheric CO2 - from about 280 to more than 380 parts per million (ppm) over the last 250 years - is causing measurable global warming. Potential adverse impacts include sea-level rise; increased frequency and intensity of wildfires, floods, droughts, and tropical storms; changes in the amount, timing, and distribution of rain, snow, and runoff; and disturbance of coastal marine and other ecosystems. Rising atmospheric CO2 is also increasing the absorption of CO2 by seawater, causing the ocean to become more acidic, with potentially disruptive effects on marine plankton and coral reefs. Technically and economically feasible strategies are needed to mitigate the consequences of increased atmospheric CO2. The United States needs scientific information to develop ways to reduce human-caused CO2 emissions and to remove CO2 from the atmosphere.

  3. Reactor refurbishment options for a changing climate

    McNeish, D. [Bruce Power, Tiverton, Ontario (Canada)

    2012-07-01

    As the industry looks ahead to another generation of reactor refurbishment, it is acknowledged that the traditional way of Retubing a reactor is a daunting prospect for our investors and stakeholders. Innovations are required to mitigate the long downtime and large one-time investment associated with previous reactor refurbishments. These can take the shape of improvements to the Retube processes or by fundamentally changing the approach, e.g., calandria/shield tank replacement or partial Retubes. This session presents technical challenges that utilities need help resolving to arrive at a more attractive reactor refurbishment model. This includes issues related to calandria vessel fitness-for-service, the fuel channel replacement process, the feeder replacement process, life extension of fuel channels and feeders and complexities involving interfacing systems.

  5. Future Arctic climate changes: Adaptation and mitigation time scales

    Overland, James E.; Wang, Muyin; Walsh, John E.; Stroeve, Julienne C.

    2014-02-01

    The climate in the Arctic is changing faster than in midlatitudes. This is shown by increased temperatures, loss of summer sea ice, earlier snow melt, impacts on ecosystems, and increased economic access. Arctic sea ice volume has decreased by 75% since the 1980s. Long-lasting global anthropogenic forcing from carbon dioxide has increased over the previous decades and is anticipated to increase over the next decades. Temperature increases in response to greenhouse gases are amplified in the Arctic through feedback processes associated with shifts in albedo, ocean and land heat storage, and near-surface longwave radiation fluxes. Thus, for the next few decades out to 2040, continuing environmental changes in the Arctic are very likely, and the appropriate response is to plan for adaptation to these changes. For example, it is very likely that the Arctic Ocean will become seasonally nearly sea ice free before 2050 and possibly within a decade or two, which in turn will further increase Arctic temperatures, economic access, and ecological shifts. Mitigation becomes an important option to reduce potential Arctic impacts in the second half of the 21st century. Using the most recent set of climate model projections (CMIP5), multimodel mean temperature projections show an Arctic-wide end of century increase of +13°C in late fall and +5°C in late spring for a business-as-usual emission scenario (RCP8.5) in contrast to +7°C in late fall and +3°C in late spring if civilization follows a mitigation scenario (RCP4.5). Such temperature increases demonstrate the heightened sensitivity of the Arctic to greenhouse gas forcing.

  6. Global climate change mitigation scenarios for solid waste management

    The waste sector is an important contributor to climate change. CH{sub 4} produced at solid waste disposal sites contributes approximately 3.4 percent to the annual global anthropogenic greenhouse gas emissions. Emissions from solid waste disposal are expected to increase with increasing global population and GDP. On the other hand, many cost-efficient emission reduction options are available. The rate of waste degradation in landfills depends on waste composition, climate and conditions in the landfill. Because the duration of CH{sub 4} generation is several decades, estimation of emissions from landfills requires modelling of waste disposal prior to the year whose emissions are of interest. In this study, country- or region-specific first-order decay (FOD) models based on the 2006 IPCC Guidelines are used to estimate emissions from municipal solid waste disposal in landfills. In addition, IPCC methodology is used to estimate emissions from waste incineration. Five global scenarios are compiled from 1990 to 2050. These scenarios take into account political decision making and changes in the waste management system. In the Baseline scenario, waste generation is assumed to follow past and current trends using population and GDP as drivers. In the other scenarios, effects of increased incineration, increased recycling and increased landfill gas recovery on greenhouse gas (GHG) emissions are assessed. Economic maximum emission reduction potentials for these waste management options are estimated at different marginal cost levels for the year 2030 by using the Global TIMES model. Global emissions from landfills are projected to increase from 340 Tg CO{sub 2} eq in 1990 to 1500 Tg CO{sub 2} eq by 2030 and 2900 Tg CO{sub 2} eq by 2050 in the Baseline scenario. The emission reduction scenarios give emissions reductions from 5% (9%) to 21% (27%) compared to the Baseline in 2030 (2050). As each scenario considered one mitigation option, the results are largely additive, and

  7. United States policy for mitigating global climate change

    Bergman, P.; Kane, R.; Kildow, J.

    1998-01-01

    The primary objective of this paper is to explain current US policy on global climate change. US Department of Energy (DOE) efforts to implement this policy are described. A secondary objective of this paper is to discuss from a US perspective the social and political efforts which must be initiated in order for ocean storage of CO 2 to be considered as a viable CO 2 mitigation option. The fact that the Framework Convention on Climate Change (FCCC) has not been successful in reducing greenhouse gas emissions is now recognized. Thus, US policy has shifted towards the development of binding medium-term emissions targets and long-term atmosphere concentration goals. The US believes these goals can be accomplished through the adoption of cost-effective joint implementation agreements and international emissions trading mechanisms. Studies are currently underway to assess specific targets and timetables for emissions reductions. Voluntary efforts on the part of US industry have proven to be extremely successful in reducing US CO 2 -emissions. The US electric utility industry has taken the lead in voluntarily lowering greenhouse gas emissions under the DOE Climate Challenge Program. Areas of research interest to DOE include the development of high efficiency advanced power generation cycles and CO 2 sequestration technology. The US currently spends $1.6 billion on understanding global climate phenomena and only $1.6 million on CO 2 mitigation research. A number of socio-political considerations must be looked at in assessing the feasibility of ocean storage of CO 2 . Developing public trust appears to be a major concern in establishing the acceptability of ocean storage. Uncertainties in the effects of CO 2 on marine life, potential safety hazards associated with pipelining, and ship transport of CO 2 are all issues which must be dealt with as soon as possible. Some hidden costs associated with ocean disposal is also discussed

    2009-03-15

    This report gives an overview of heat stress problems in urban areas of the Netherlands and various options for mitigating this stress. Climate change is causing more occurrences of heat waves. Urban areas in particular will suffer the most, as they are warmer than the countryside. What is known about the magnitude of heat stress in Dutch urban areas? What are the consequences? What research is needed to clarify its effects? Which options in particular could do with further study in order to prevent fatalities, maintain comfort levels and avoid increases in energy consumption for summer cooling? This report aims at identifying: the foreseeable problems of urban heat in the Netherlands; the specifics (geographic, cultural, economic, technological) that apply to the Netherlands; the most promising options for mitigating urban heat; and the priorities for further research.

We propose a transdisciplinary approach to identify demand-side climate solutions, investigate their mitigation potential, detail policy measures and assess their implications for well-being.

  10. Water Quality, Mitigation Measures of Arsenic Contamination and Sustainable Rural Water Supply Options in Bangladesh

    HOSSAIN M. ANAWAR

    2012-06-01

    Full Text Available Arsenic contamination of groundwater has created a serious public health issue in Bangladesh and West Bengal (India, because groundwater is widely used for drinking, household and agriculture purposes. Given the magnitude of the problem of groundwater contamination facing Bangladesh, effective, acceptable and sustainable solutions are urgently required. Different NGOs (Non-government organizations and research organizations are using their extensive rural networks to raise awareness and conduct pilot projects. The implication of the results from the previous studies is robust, but coastly arsenic reduction technologies such as activated alumina technology, and As and Fe removal filters may find little social acceptance, unless heavily subsidized. This review paper analysed the quality of surface water and ground water, all mitigation measures and the most acceptable options to provide sustainable access to safe- water supply in the rural ares of Bangladesh. Although there are abundant and different sources of surface water, they can not be used for drinking and hosehold purposes due to lack of sanitation, high faecal coliform concentration, turibidity and deterioration of quality of surface water sources. There are a few safe surface water options; and also there are several methods available for removal of arsenic and iron from groundwater in large conventional treatments plants. This review paper presented a short description of the currently available and most sustainable technologies for arsenic and iron removal, and alternative water supply options in the rural areas.

  11. Incorporating changes in albedo in estimating the climate mitigation benefits of land use change projects

    Bird, D. N.; Kunda, M.; Mayer, A.; Schlamadinger, B.; Canella, L.; Johnston, M.

    2008-04-01

    Some climate scientists are questioning whether the practice of converting of non-forest lands to forest land (afforestation or reforestation) is an effective climate change mitigation option. The discussion focuses particularly on areas where the new forest is primarily coniferous and there is significant amount of snow since the increased climate forcing due to the change in albedo may counteract the decreased climate forcing due to carbon dioxide removal. In this paper, we develop a stand-based model that combines changes in surface albedo, solar radiation, latitude, cloud cover and carbon sequestration. As well, we develop a procedure to convert carbon stock changes to equivalent climatic forcing or climatic forcing to equivalent carbon stock changes. Using the model, we investigate the sensitivity of combined affects of changes in surface albedo and carbon stock changes to model parameters. The model is sensitive to amount of cloud, atmospheric absorption, timing of canopy closure, carbon sequestration rate among other factors. The sensitivity of the model is investigated at one Canadian site, and then the model is tested at numerous sites across Canada. In general, we find that the change in albedo reduces the carbon sequestration benefits by approximately 30% over 100 years, but this is not drastic enough to suggest that one should not use afforestation or reforestation as a climate change mitigation option. This occurs because the forests grow in places where there is significant amount of cloud in winter. As well, variations in sequestration rate seem to be counterbalanced by the amount and timing of canopy closure. We close by speculating that the effects of albedo may also be significant in locations at lower latitudes, where there are less clouds, and where there are extended dry seasons. These conditions make grasses light coloured and when irrigated crops, dark forests or other vegetation such as biofuels replace the grasses, the change in carbon

  12. Beyond pure offsetting: Assessing options to generate Net-Mitigation-Effects in carbon market mechanisms

    Warnecke, Carsten; Wartmann, Sina; Höhne, Niklas; Blok, Kornelis

    2014-01-01

    The current project-based carbon market mechanisms such as the Clean Development Mechanism (CDM) and the Joint Implementation (JI) do not have a direct impact on global greenhouse gas emission levels, because they only replace or offset emissions. Nor do they contribute to host country's national greenhouse gas emission reduction targets. Contributions to net emission reductions in host countries is likely to become mandatory in new mechanisms under development such as in the framework for various approaches, a new market-based mechanism and even in a reformed JI. This research analysed the question if approaches for carbon market-based mechanisms exist that allow the generation of net emission reductions in host countries while keeping project initiation attractive. We present a criteria-based assessment method and apply it for four generic options in existing mechanisms and derive implications for future mechanism frameworks. We identified the application of “discounts” on the amount of avoided emissions for the issuance of carbon credits and “standardisation below business as usual” as most promising options over “limiting the crediting period” and “over-conservativeness”. We propose to apply these options differentiated over project types based on internal rate of return to ensure cost-efficiency and attractiveness. - Highlights: • Options for net emission reductions of market-based mechanisms are assessed. • Research combines past and current views for project and sector-based mechanisms. • Implementation ensures initiation of mitigation activities is not discouraged. • Important insights for methodological design of new market-based mechanisms. • Profitability-based approach for project-based mechanisms suggested

  13. Industrial Energy Efficiency and Climate Change Mitigation

    Worrell, Ernst; Bernstein, Lenny; Roy, Joyashree; Price, Lynn; de la Rue du Can, Stephane; Harnisch, Jochen

    2009-02-02

    Industry contributes directly and indirectly (through consumed electricity) about 37% of the global greenhouse gas emissions, of which over 80% is from energy use. Total energy-related emissions, which were 9.9 GtCO2 in 2004, have grown by 65% since 1971. Even so, industry has almost continuously improved its energy efficiency over the past decades. In the near future, energy efficiency is potentially the most important and cost-effective means for mitigating greenhouse gas emissions from industry. This paper discusses the potential contribution of industrial energy efficiency technologies and policies to reduce energy use and greenhouse gas emissions to 2030.

  14. Integrated energy planning: Strategies to mitigate climate change

    Ortiz, Johnny N; Sheffield, John W [University of Missouri-Rolla (United States)

    1997-07-01

    The framework convention on climate change, signed by more than 150 governments worldwide in June 1992, calls on parties to the convention undertaken inventories of national sources and sinks of greenhouse gases and to develop plans for responding to climate change. The energy sector is comprised of the major energy demand sectors (industry, residential and commercial, transport and agriculture), and the energy supply sector, which consists of resource extraction, conversion, and delivery of energy products. Greenhouse Gas (GHG) emissions occur at various points in the sector, from resource extraction to end use application, and accordingly, options for mitigation exist at various points. In most countries, will be a major focus of GHG mitigation analysis. The primary focus of this paper is on the identification of strategies that can mitigate climate changes on the basis of integrated energy planing analysis. The overall approach follows a methodology developed by the U.S. Country Studies Program under the framework of the Convention's commitments. It involves the development of scenarios based on energy uses and evaluation of specific technologies that can satisfy demands for energy services. One can compare technologies based on their relative cost to achieve a unit of GHG reduction and other features of interest. This approach gives equal weight to both energy supply and energy demand options. A variety of screening criteria including indicators of cost-effectiveness as well as non-economic analysis concerns, can be used to identify and assess promising options, which can then be combined to create one or more scenarios. Mitigation scenarios are evaluated against the backdrop of a baseline scenario, which simulates assumed to take place in the absence of mitigation efforts. Mitigation scenarios can be designed to meet specific emission reduction targets or to simulate the effect of specific policy inventions. The paper ends with an application using a

  15. Climate change, nuclear power, and the adaptation-mitigation dilemma

    Kopytko, Natalie; Perkins, John

    2011-01-01

    Many policy-makers view nuclear power as a mitigation for climate change. Efforts to mitigate and adapt to climate change, however, interact with existing and new nuclear power plants, and these installations must contend with dilemmas between adaptation and mitigation. This paper develops five criteria to assess the adaptation-mitigation dilemma on two major points: (1) the ability of nuclear power to adapt to climate change and (2) the potential for nuclear power operation to hinder climate change adaptation. Sea level rise models for nine coastal sites in the United States, a review of US Nuclear Regulatory Commission documents, and reports from France's nuclear regulatory agency provided insights into issues that have arisen from sea level rise, shoreline erosion, coastal storms, floods, and heat waves. Applying the criteria to inland and coastal nuclear power plants reveals several weaknesses. Safety stands out as the primary concern at coastal locations, while inland locations encounter greater problems with interrupted operation. Adapting nuclear power to climate change entails either increased expenses for construction and operation or incurs significant costs to the environment and public health and welfare. Mere absence of greenhouse gas emissions is not sufficient to assess nuclear power as a mitigation for climate change. - Research Highlights: → The adaptation-mitigation criteria reveal nuclear power's vulnerabilities. → Climate change adaptation could become too costly at many sites. → Nuclear power operation jeopardizes climate change adaptation. → Extreme climate events pose a safety challenge.

  16. An informal judgment assessment of subsidence mitigation options for low-level radioactive waste management on the Nevada Test Site

    Crowe, B.M.; Besinger, H.; Dolenc, M.

    1999-01-01

    An assessment of options to mitigate the effects of subsidence at low-level radioactive waste disposal sites on the Nevada Test Site was conducted using an informal method of expert judgment. Mitigation options for existing waste cells and future waste cells were identified by a committee composed of knowledgeable personnel from the DOE and DOE-contractors. Eight ranking factors were developed to assess the mitigation options and these factors were scored through elicitation of consensus views from the committee. Different subsets of the factors were applied respectively, to existing waste cells and future waste cells, and the resulting scores were ranked using weighted and unweighted scores. These scores show that there is a large number of viable mitigation options and considerable flexibility in assessing the subsidence issue with a greater range of options for future waste cells compared to existing waste cells. A highly ranked option for both existing and future waste cells is covering the waste cells with a thick closure cap of native alluvium

  19. Mitigation options for methane emissions from rice fields in the Philippines

    1996-12-31

    The contribution of Philippine rice production to global methane emission and breakthroughs in methane emission studies conducted in the country are presented in this paper. A significant impact in the reduction of GHG emissions from agriculture can be achieved if methane emissions from ricefields can be abated. This study presents the contribution of Philippine rice cultivation to global methane emission and breakthroughs in methane emission studies in the country which address the issue of mitigation. Using the derived emission factors from local measurements, rice cultivation contributes 566.6 Gg of methane emission in the Philippines. This value is 62% of the total methane emitted from the agriculture sector. The emission factors employed which are 78% of the IPCC value for irrigated rice and 95% for rainfed rice were derived from measurements with an automatic system taken during the growth duration in the respective ecosystems. Plots drained for 2 weeks at midtillering and before harvest gave a significant reduction in methane emission as opposed to continuously flooded plots and plots drained before harvest. The cultivar Magat reduced methane emission by 50% as compared to the check variety IR72. The application of ammonium sulfate instead of urea reduced methane emission by 10% to 34%. Addition of 6 t ha{sup {minus}1} phosphogypsum in combination with urea reduced emission by 74% as opposed to plots applied with urea alone. It is also from the results of such measurements that abatement strategies are based as regards to modifying treatments such as water management, fertilization, and choice of rice variety. It is not easy to identify and recommend mitigation strategies that will fit a particular cropping system. However, the identified mitigation options provide focus for the abatement of methane emission from ricefields.

    The options outlined in this guidebook are designed to assist you in the process of developing transport services and facilities in your countries and localities - transport that better serves people's needs and enhances their lives while at the same time producing fewer greenhouse gas emissions. This is a new challenge, as previously improving transport generally led to increased greenhouse gases. The challenge now is to provide transport that: 1) is cheaper, more extensive and better quality 2) reduces pollution, congestion, traffic accidents and other threats to health and wellbeing 3) is accessible to all 4) supports economic development 5) reduces greenhouse emissions overall. This can be achieved if: 1) mass transit, walking and cycling are supported and encouraged, and integrated in a way that allows seamless multimodal travel, including networks of taxis, auto-rickshaws and small buses. 2) the mass transit services - including trains, buses and light-rail - are frequent, extensive, attractive, comfortable, affordable and faster than alternatives, with features like integrated ticketing and real time information accessible through mobile phones and other sources 3) private vehicle use and air travel are discouraged through pricing and other demand management measures, and through the availability of better alternative modes 4) there is support for the adoption of cleaner, lower carbon fuels and technologies and better maintenance practices for all transport modes, including private vehicles, water transport, auto-rickshaws and freight vehicles 5) the overall need for travel is reduced through the development of denser localities with more mixed land use and better access to mass transit (which reduces overall travel in ways that will be explained) 6) travel space is better managed to give higher priority to more sustainable transport modes, to promote safety, and to prevent traffic from adversely affecting residents and businesses.

    2007-01-01

    The Working Group III contribution to the IPCC Fourth Assessment Report (AR4) focuses on new literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change, published since the IPCC Third Assessment Report (TAR) and the Special Reports on CO 2 Capture and Storage (SRCCS) and on Safeguarding the Ozone Layer and the Global Climate System (SROC).The main aim of this summary report is to assess options for mitigating climate change. Several aspects link climate change with development issues. This report explores these links in detail, and illustrates where climate change and sustainable development are mutually reinforcing. Economic development needs, resource endowments and mitigative and adaptive capacities differ across regions. There is no one-size-fits-all approach to the climate change problem, and solutions need to be regionally differentiated to reflect different socio-economic conditions and, to a lesser extent, geographical differences. Although this report has a global focus, an attempt is made to differentiate the assessment of scientific and technical findings for the various regions. Given that mitigation options vary significantly between economic sectors, it was decided to use the economic sectors to organize the material on short- to medium-term mitigation options. Contrary to what was done in the Third Assessment Report, all relevant aspects of sectoral mitigation options, such as technology, cost, policies etc., are discussed together, to provide the user with a comprehensive discussion of the sectoral mitigation options. The report is organised into six sections after the introduction: - Greenhouse gas (GHG) emission trends; - Mitigation in the short and medium term, across different economic sectors (until 2030); - Mitigation in the long-term (beyond 2030); - Policies, measures and instruments to mitigate climate change; - Sustainable development and climate change mitigation; - Gaps in

  5. Options and potentials to mitigate N2O emissions from wheat and maize fields in China: a meta-analysis

    Sun, W.; Li, X.

    2017-12-01

    Upland croplands are the main source of N2O emission. Mitigation of N2O emissions from upland croplands will greatly contribute to an overall reduction of greenhouse gases from agriculture. We performed a meta-analysis to investigate the mitigation options and potential of N2O emissions from wheat and maize fields in China. Results showed that application of inhibitors in wheat and maize fields reduced36‒46% of the N2O emissions with an increase in crop yield. Cutting the application rates of nitrogen fertilizers by no more than 30% could reduce N2O emissions by 10‒18%without crop yield loss. Applications of slow (controlled-) release fertilizer fertilizers and incorporations of crop residues can significantly mitigate N2O emission from wheat fields, but this mitigation is not statistically significant in maize fields. The gross N2O emission could be reduced by 9.3‒13.9Gg N2O-N per wheat season and 10.5‒23.2 Gg N2O-N per maize season when different mitigation options are put into practices. The mitigation potential (MP) in wheat cultivation is particularly notable for Henan, Shandong, Hebei and Anhui Province, contributing 53% to the total MP in wheat fields. Heilongjiang, Jilin, Shandong, Hebei and Henan Province showed high MP in maize cultivation, accounting for approximately 50% of the total MP in maize fields.

  9. Fuel carbon intensity standards may not mitigate climate change

    Plevin, Richard J.; Delucchi, Mark A.; O’Hare, Michael

    2017-01-01

    To mitigate the climate change effects of transportation, the US states of California and Oregon, the Canadian province of British Columbia, and the European Union have implemented regulations to reduce the life cycle greenhouse gas (GHG) emissions intensity of transport fuel, commonly referred to as 'carbon intensity', or CI. In this article, we unpack the theory and practice of fuel CI standards, examining claims regarding climate-change mitigation. We show that these standards do not reliably mitigate climate change because estimates of GHG reductions rely primarily on models that are not designed to estimate changes in emissions and climate impacts. Some regulations incorporate models that estimate a subset of changes in emissions, but the models must project changes in global markets over decades, and there is little agreement about the best model structure or parameter values. Since multiple models and projections may be equally plausible, fuel CI is inevitably subjective and unverifiable. We conclude that regulating or taxing observable emissions would more reliably achieve emission reduction. - Highlights: • Use of fuel carbon intensity (CI) standards has been expanding recently. • Fuel CI ratings are subjective, scenario- and model-dependent. • Uncertainty in fuel CI ratings creates uncertainty in policy outcomes. • There is no reliable test of whether fuel CI standards mitigate climate change. • Regulating or taxing observable emissions would be a more reliable approach.

  10. Climate change mitigation in the energy sector of developing countries

    1998-01-01

    The Framework Convention on Climate change, singed by more than 150 governments worldwide, calls on parties to the Convention to undertake inventories of national sources and sinks of greenhouse gases and to develop plans for responding to climate change. Several institutions, including UNEP, have initiated programs to assist developing countries and countries with economies in transition to meet this obligation. This paper describes a mitigation methodology that is being used for these country studies, and discusses issues that have arisen in conducting mitigation assessments for developing countries in the past.

  13. Climate change and livestock: Impacts, adaptation, and mitigation

    M. Melissa Rojas-Downing

    2017-01-01

    Full Text Available Global demand for livestock products is expected to double by 2050, mainly due to improvement in the worldwide standard of living. Meanwhile, climate change is a threat to livestock production because of the impact on quality of feed crop and forage, water availability, animal and milk production, livestock diseases, animal reproduction, and biodiversity. This study reviews the global impacts of climate change on livestock production, the contribution of livestock production to climate change, and specific climate change adaptation and mitigation strategies in the livestock sector. Livestock production will be limited by climate variability as animal water consumption is expected to increase by a factor of three, demand for agricultural lands increase due to need for 70% growth in production, and food security concern since about one-third of the global cereal harvest is used for livestock feed. Meanwhile, the livestock sector contributes 14.5% of global greenhouse gas (GHG emissions, driving further climate change. Consequently, the livestock sector will be a key player in the mitigation of GHG emissions and improving global food security. Therefore, in the transition to sustainable livestock production, there is a need for: a assessments related to the use of adaptation and mitigation measures tailored to the location and livestock production system in use, and b policies that support and facilitate the implementation of climate change adaptation and mitigation measures.

  14. Mapping of soil organic carbon stocks for spatially explicit assessments of climate change mitigation potential

    Vågen, Tor-Gunnar; Winowiecki, Leigh A

    2013-01-01

    Current methods for assessing soil organic carbon (SOC) stocks are generally not well suited for understanding variations in SOC stocks in landscapes. This is due to the tedious and time-consuming nature of the sampling methods most commonly used to collect bulk density cores, which limits repeatability across large areas, particularly where information is needed on the spatial dynamics of SOC stocks at scales relevant to management and for spatially explicit targeting of climate change mitigation options. In the current study, approaches were explored for (i) field-based estimates of SOC stocks and (ii) mapping of SOC stocks at moderate to high resolution on the basis of data from four widely contrasting ecosystems in East Africa. Estimated SOC stocks for 0–30 cm depth varied both within and between sites, with site averages ranging from 2 to 8 kg m −2 . The differences in SOC stocks were determined in part by rainfall, but more importantly by sand content. Results also indicate that managing soil erosion is a key strategy for reducing SOC loss and hence in mitigation of climate change in these landscapes. Further, maps were developed on the basis of satellite image reflectance data with multiple R-squared values of 0.65 for the independent validation data set, showing variations in SOC stocks across these landscapes. These maps allow for spatially explicit targeting of potential climate change mitigation efforts through soil carbon sequestration, which is one option for climate change mitigation and adaptation. Further, the maps can be used to monitor the impacts of such mitigation efforts over time. (letter)

  15. Potential for carbon sequestration and mitigation of climate change by irrigation of grasslands

    Olsson, Alexander; Campana, Pietro Elia; Lind, Mårten; Yan, Jinyue

    2014-01-01

    Highlights: • A generic method for climate change mitigation feasibility of PVWPS is developed. • Restoration of degraded lands in China has large climate change mitigation potential. • PV produces excess electricity included in the mitigation potential of the system. • The benefit is higher than if the PV were to produce electricity for the grid only. - Abstract: The climate change mitigation potential of irrigation powered by a photovoltaic water pumping system (PVWPS) to restore degraded grasslands has been investigated using the Intergovernmental Panel on Climate Change (IPCC) 2006 Guidelines for National Greenhouse Gas Inventories for Agriculture, Forestry and Other Land Use. The purpose of this study is to develop a generic and simple method to estimate the climate change mitigation benefit of a PVWPS. The possibility to develop carbon credits for the carbon offset markets has also been studied comparing carbon sequestration in grasslands to other carbon sequestration projects. The soil carbon sequestration following irrigation of the grassland is calculated as an annual increase in the soil organic carbon pool. The PVWPS can also generate an excess of electricity when irrigation is not needed and the emissions reductions due to substitution of grid electricity give additional climate change mitigation potential. The results from this study show that the carbon sequestration and emissions reductions benefits per land area using a PVWPS for irrigating grasslands are comparable to other carbon sequestration options such as switching to no-till practice. Soil carbon in irrigated grasslands is increased with over 60% relative to severely degraded grasslands and if nitrogen fixing species are introduced the increase in soil organic carbon can be almost 80%. Renewable electricity generation by the PVWPS will further increase the mitigation benefit of the system with 70–90%.

  16. Mitigating cyanobacterial harmful algal blooms in aquatic ecosystems impacted by climate change and anthropogenic nutrients.

    Paerl, Hans W; Gardner, Wayne S; Havens, Karl E; Joyner, Alan R; McCarthy, Mark J; Newell, Silvia E; Qin, Boqiang; Scott, J Thad

    2016-04-01

    Mitigating the global expansion of cyanobacterial harmful blooms (CyanoHABs) is a major challenge facing researchers and resource managers. A variety of traditional (e.g., nutrient load reduction) and experimental (e.g., artificial mixing and flushing, omnivorous fish removal) approaches have been used to reduce bloom occurrences. Managers now face the additional effects of climate change on watershed hydrologic and nutrient loading dynamics, lake and estuary temperature, mixing regime, internal nutrient dynamics, and other factors. Those changes favor CyanoHABs over other phytoplankton and could influence the efficacy of control measures. Virtually all mitigation strategies are influenced by climate changes, which may require setting new nutrient input reduction targets and establishing nutrient-bloom thresholds for impacted waters. Physical-forcing mitigation techniques, such as flushing and artificial mixing, will need adjustments to deal with the ramifications of climate change. Here, we examine the suite of current mitigation strategies and the potential options for adapting and optimizing them in a world facing increasing human population pressure and climate change.

  17. Cities in Climate Change Mitigation Policy

    Paugam, Anne; Giraud, Gael; Thauvin, Eric

    2015-03-01

    The phenomenon of accelerated urbanization of emerging and developing economies is a potential source of harmful environmental impacts on people's well-being. Major negative effects can especially be expected on the climate, possibly compromising, in the long run, large-scale local economic development. This is because the urban environment is characterized by a concentration of activities with high energy consumption (between 56 and 78% of final energy used is ascribable to transportation and buildings, as well as to industries and services). These activities, in addition to generating significant local pollution, are a large source of greenhouse gas (GHG) emissions. Due to divergent methods of calculation as well as to the perimeter of urban activities, there is uncertainty about the exact extent to which these activities contribute to GHG. Nonetheless, a strong increase in the overall impact of cities on climate change can be expected. The international community wants to reach a coordinated commitment to keep global warming between now and the end of the 21. century under the threshold of an average 2 deg. C higher than the temperature of the pre-industrial age and thereby prevent irreversible damage from climate disturbance. This comes down to examining the potential of cities to contribute to implementing effective solutions. However, analysis of mid- to long-term impacts of urban development strategies on GHG emissions is still difficult, due to great complexity of the underlying impact mechanisms. Because of the large number of sectors and services concerned (transportation infrastructures and networks, energy-management services, and urban spatial planning), urban development strategies can simultaneously have a direct and indirect effect on several sources of GHG emissions. They are also highly dependent on each country's competence level and institutional organization. Despite this complexity, the urgency of the climate issues linked to growing

    2010-07-01

    activities may change emissions between 2012 and 2025. While exhaustion coal reserves and thereby abandonment of Norwegian mining activities at Svalbard will bring CO{sub 2} emissions down below 2007 levels, a potential doubling of the tourist related activities will cause emissions to increase significantly (25%). Some measures and mitigation options are discussed. Local electric power production and marine transport activities (tourist cruises and coal shipping) have been identified as predominant emission sources. Thus, for regulation purposes aiming at short-term effects, these major emission sources should be targeted.

  3. A country framework for analyzing climate change mitigation

    King, K.

    1995-01-01

    Once the global community accepted the threat of global climate change as a serious one, many countries began to study its possible consequences and the scope for national action that could help mitigate it. Governments will find that national climate change studies are useful quite apart from helping them to fulfill commitments under the FCCC. All countries, developed and developing, will benefit from an understanding of the sacrifice they need to make for the greater benefit of climate change mitigation. This sacrifice - that is, the set of trade-offs or the 'added burden' - is what economists refer to as the 'incremental cost' of climate change mitigation actions. All countries will benefit from knowing what these costs are and from knowing how much their national action will matter. Using measures of cost and mitigation, they will be able to choose from among their alternative national actions those with the greatest effect and the lowest incremental cost. Eligible countries can also use these measures to negotiate the amount of financial assistance they need from the financial mechanism of the FCCC or other sources. A country framework for medium-term considerations will yield results useful for investment planning, policy choice, and financial reimbursement (where appropriate). This is the focus of the framework outlined in this paper. (EG) 15 refs

  4. The next generation of urban MACCs. Reassessing the cost-effectiveness of urban mitigation options by integrating a systemic approach and social costs

    Saujot, Mathieu; Lefèvre, Benoit

    2016-01-01

    Many cities are implementing policies and climate action plans. Yet local climate policies suffer from a lack of scientific understanding and evaluation methods able to support the definition of efficient mitigation strategies. The purpose of this paper is to build on classical approaches in the energy policy field that exist at the national and international level to propose an urban MACCs methodology able to fulfill this lack and inform local debates. The methodology is an extension of static “expert-based” MACCs; it combines a land use transport integrated model and an abatement cost methodology that integrates co-benefits, and takes into account the spatial and systemic dimensions of cities. The methodology is implemented for the transportation sector of a mid-sized European city (Grenoble, France). Our results present the cost-effectiveness and political feasibility of several proposed measures. We find that the inclusion of co-benefits can profoundly change the cost-benefit assessment of transport mitigation options. Moreover we underline the key parameters determining the cost-effectiveness ranking of mitigation options. These urban MACCs aim to serve as a bridge between urban planning and mitigation policies and can thus contribute to strengthen and align sustainable and climate change agendas at the local level. - Highlights: •Local climate policies lack scientific understanding for prioritizing mitigation actions. •We develop a method to evaluate cost-effectiveness of urban transportation actions. •This method combines urban modeling and MACCs to inform urban planning. •Abatement costs from its application to a mid-sized city are presented. •The impact of the inclusion of co-benefits is analyzed.

  5. Alternative energy balances for Bulgaria to mitigate climate change

    Christov, Christo

    1996-01-01

    Alternative energy balances aimed to mitigate greenhouse gas (GHG) emissions are developed as alternatives to the baseline energy balance. The section of mitigation options is based on the results of the GHG emission inventory for the 1987 1992 period. The energy sector is the main contributor to the total CO2 emissions of Bulgaria. Stationary combustion for heat and electricity production as well as direct end-use combustion amounts to 80% of the total emissions. The parts of the energy network that could have the biggest influence on GHG emission reduction are identified. The potential effects of the following mitigation measures are discussed: rehabilitation of the combustion facilities currently in operation; repowering to natural gas; reduction of losses in thermal and electrical transmission and distribution networks; penetration of new combustion technologies; tariff structure improvement; renewable sources for electricity and heat production; wasteheat utilization; and supply of households with natural gas to substitute for electricity in space heating and cooking. The total available and the achievable potentials are estimated and the implementation barriers are discussed.

  6. An evaluation of greenhouse gas mitigation options for coal-fired power plants in the US Great Lakes States

    Froese, Robert E.; Shonnard, David R.; Miller, Chris A.; Koers, Ken P.; Johnson, Dana M.

    2010-01-01

    We assessed options for mitigating greenhouse gas emissions from electricity generation in the US Great Lakes States, a region heavily dependent on coal-fired power plants. A proposed 600 MW power plant in northern Lower Michigan, USA provided context for our evaluation. Options to offset fossil CO 2 emissions by 20% included biomass fuel substitution from (1) forest residuals, (2) short-rotation woody crops, or (3) switchgrass; (4) biologic sequestration in forest plantations; and (5) geologic sequestration using CO 2 capture. Review of timber product output data, land cover data, and expected energy crop productivity on idle agriculture land within 120 km of the plant revealed that biomass from forestry residuals has the potential to offset 6% and from energy crops 27% of the annual fossil fuel requirement. Furthermore, annual forest harvest in the region is only 26% of growth and the surplus represents a large opportunity for forest products and bioenergy applications. We used Life Cycle Assessment (LCA) to compare mitigation options, using fossil energy demand and greenhouse gas emissions per unit electricity generation as criteria. LCA results revealed that co-firing with forestry residuals is the most attractive option and geologic sequestration is the least attractive option, based on the two criteria. Biologic sequestration is intermediate but likely infeasible because of very large land area requirements. Our study revealed that biomass feedstock potentials from land and forest resources are not limiting mitigation activities, but the most practical approach is likely a combination of options that optimize additional social, environmental and economic criteria.

  8. Net climate change mitigation of the Clean Development Mechanism

    Erickson, Peter; Lazarus, Michael; Spalding-Fecher, Randall

    2014-01-01

    The Clean Development Mechanism (CDM) has allowed industrialized countries to buy credits from developing countries for the purpose of meeting targets under the Kyoto Protocol. In principle, the CDM simply shifts the location of emission reductions, with no net mitigation impact. Departing from this zero-sum calculus, the Cancun Agreements reached at the sixteenth session of the Conference of the Parties (COP) in 2010 called for “one or more market-based mechanisms” capable of “ensuring a net decrease and/or avoidance of global greenhouse gas emissions”, an intention reiterated at COP 17 and COP 18. This article explores the extent to which the CDM may or may not already lead to such a “net decrease.” It finds that the CDM's net mitigation impact likely hinges on the additionality of large-scale power projects, which are expected to generate the majority of CDM credits going forward. If these projects are truly additional and continue to operate well beyond the credit issuance period, they will decrease global greenhouse gas emissions. However, if they are mostly non-additional, as research suggests, they could increase global greenhouse gas emissions. The article closes with a discussion of possible means to increase mitigation benefit. - Highlights: • The CDM's method for assessing additionality remains controversial and contested. • We develop two scenarios of the net emissions impact of the CDM. • The integrity of the CDM hinges on the emissions impact of power supply projects. • Additionality is hard to demonstrate with confidence for most power-supply projects. • A number of options are available to increase the mitigation benefit of the CDM

  10. Energy and emission scenarios for China in the 21st century - exploration of baseline development and mitigation options

    Vuuren, Detlef van; Zhou Fengqi; Vries, Bert de; Jiang Kejun; Graveland, Cor; Li Yun

    2003-01-01

    In this paper, we have used the simulation model IMAGE/TIMER to develop a set of energy and emission scenarios for China between 1995 and 2100, based on the global baseline scenarios published by IPCC. The purpose of the study was to explore possible baseline developments and available options to mitigate emissions. The two main baseline scenarios of the study differ, among others, in the openness of the Chinese economy and in economic growth, but both indicate a rapid growth in carbon emissions (2.0% and 2.6% per year in the 2000-2050 period). The baseline scenario analysis also shows that an orientation on environmental sustainability can not only reduce other environmental pressures but also lower carbon emissions. In the mitigation analysis, a large number of options has been evaluated in terms of impacts on investments, user costs, fuel imports costs and emissions. It is found that a large potential exists to mitigate carbon emissions in China, among others in the form of energy efficiency improvement (with large co-benefits) and measures in the electricity sector. Combining all options considered, it appears to be possible to reduce emissions compared to the baseline scenarios by 50%

    Highlights: • Mitigation of the radiation environment inside the cryostat needed to reduce ITER coil heating and occupational exposure. • Cryopump and diagnostics lower ports are significant contributors, shielding options for both are explored. • Shielding performance studied in terms of neutron transmission and nuclear heating to coils for a range of options. • Benefits/constraints discussed together with other engineering parameters. - Abstract: Mitigation of the neutron environment inside the cryostat, and of the subsequent decay gamma dose field from activated materials, is necessary in order to reduce heating of coils and occupational exposure, thereby facilitating smooth operation and maintenance of ITER. Several lines of action are currently being explored to mitigate crucial contributions, such as the leakage through the lower ports. Results are presented here for the two types of lower ports in ITER: cryopump ports and remote-handling ports. Different shielding configurations and material options are investigated and compared in terms of neutron attenuation, coil heating and shutdown dose rate reduction, whilst also considering other engineering constraints such as weight or pumping power. Results enable informed decision-making of best compromise solutions for subsequent design and integration.

    2013-01-01

    Full Text Available This paper explores brownfield renewal as a measure of sustainable land use. The aim was to highlight the brownfield redevelopment as a strategy for mitigation of negative effects of climate changes. Emphasis was put on innovative concepts in brownfield redevelopment, which involve land recycling, application of ecological and sustainable solutions. Main case studies are from Austria. Their analysis and evaluation show which concepts and strategies are used in successful redevelopment projects, and which strategies give the best results. This shows that brownfield renewal can have positive effects on regulation and mitigation of climate changes. Finally, guidelines for climate changes accountable and redevelopment will be derived. Research methodology is qualitative and combined, comprising of data analysis, case studies (field work, interviews with relevant actors, analysis of case studies and evaluation according to previously defined criteria, synthesis of results and generalisation and interpretation of results.

  14. Toward a protocol for quantifying the greenhouse gas balance and identifying mitigation options in smallholder farming systems

    GHG budgets for developing economies. This dearth of information constrains the capacity to transition to low-carbon agricultural development, opportunities for smallholders to capitalize on carbon markets, and the negotiating position of developing countries in global climate policy discourse. Concerns over the poor state of information, in terms of data availability and representation, have fueled appeals for new approaches to quantifying GHG emissions and removals from smallholder agriculture, for both existing conditions and mitigation interventions (Berry and Ryan 2013, Olander et al 2013). Considering the dependence of quantification approaches on data and the current data deficit for smallholder systems, it is clear that in situ measurements must be a core part of initial and future strategies to improve GHG inventories and develop mitigation measures for smallholder agriculture. Once more data are available, especially for farming systems of high priority (e.g., those identified through global and regional rankings of emission hotspots or mitigation leverage points), better cumulative estimates and targeted actions will become possible. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone. These challenges are exacerbated by the heterogeneity of smallholder systems and landscapes and the diversity of methods used. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements—'a protocol'—for quantifying GHG emissions from smallholder agriculture. A standard protocol for use by scientists and development organizations will help generate consistent, comparable, and reliable data on emissions baselines and allow rigorous comparisons of mitigation options. Besides enhancing data utility, a protocol serves as a benchmark for non-experts to easily assess data

  16. Options for support to agriculture and food security under climate change

    Vermeulen, S.J.; Aggarwal, P.K.; Ainslie, A.; Angelone, C.; Campbell, B.M.; Challinor, A.J.; Hansen, J.W.

    2012-01-01

    Agriculture and food security are key sectors for intervention under climate change. Agricultural production is highly vulnerable even to 2C (low-end) predictions for global mean temperatures in 2100, with major implications for rural poverty and for both rural and urban food security. Agriculture also presents untapped opportunities for mitigation, given the large land area under crops and rangeland, and the additional mitigation potential of aquaculture. This paper presents a summary of current knowledge on options to support farmers, particularly smallholder farmers, in achieving food security through agriculture under climate change. Actions towards adaptation fall into two broad overlapping areas: (1) accelerated adaptation to progressive climate change over decadal time scales, for example integrated packages of technology, agronomy and policy options for farmers and food systems, and (2) better management of agricultural risks associated with increasing climate variability and extreme events, for example improved climate information services and safety nets. Maximization of agriculture's mitigation potential will require investments in technological innovation and agricultural intensification linked to increased efficiency of inputs, and creation of incentives and monitoring systems that are inclusive of smallholder farmers. Food systems faced with climate change need urgent, broad-based action in spite of uncertainties.

  18. Potentials to mitigate climate change using biochar - the Austrian perspective

    Bruckman, Viktor J.; Klinglmüller, Michaela; Liu, Jay; Uzun, Basak B.; Varol, Esin A.

    2015-04-01

    Biomass utilization is seen as one of various promising strategies to reduce additional carbon emissions. A recent project on potentials of biochar to mitigate climate change (FOREBIOM) goes even a step further towards bioenergy in combination of CCS or "BECS" and tries to assess the current potentials, from sustainable biomass availability to biochar amendment in soils, including the identification of potential disadvantages and current research needs. The current report represents an outcome of the 1st FOREBIOM Workshop held in Vienna in April, 2013 and tries to characterize the Austrian perspective of biochar for climate change mitigation. The survey shows that for a widespread utilization of biochar in climate change mitigation strategies, still a number of obstacles have to be overcome. There are concerns regarding production and application costs, contamination and health issues for both producers and customers besides a fragmentary knowledge about biochar-soil interactions specifically in terms of long-term behavior, biochar stability and the effects on nutrient cycles. However, there are a number of positive examples showing that biochar indeed has the potential to sequester large amounts of carbon while improving soil properties and subsequently leading to a secondary carbon sink via rising soil productivity. Diversification, cascadic utilization and purpose designed biochar production are key strategies overcoming initial concerns, especially regarding economic aspects. A theoretical scenario calculation showed that relatively small amounts of biomass that is currently utilized for energy can reduce the gap between Austria's current GHG emissions and the Kyoto target by about 30% if biomass residues are pyrolized and biochar subsequently used as soil amendment. However, by using a more conservative approach that is representing the aims of the underlying FOREBIOM project (assuming that 10% of the annual biomass increment from forests is used for biochar

    This report inventories Cherokee County's capabilities and CNS project characteristics, projects expected impacts from the interaction of the two defines four options for Cherokee County decision makers, and presents a range of possible mitigation and monitoring plans for dealing with the problems identified. The four options and general implementation guidelines for each are presented after reviewing pertinent features of other mitigation and monitoring plans. The four options include (1) no action, (2) preventing impacts by preventing growth, (3) selective growth in designated areas as services can be supplied, and (4) maximum growth designed to attract as many in-movers as possible through a major program of capital investiments in public and private services. With the exception of the no action option, all plans deal with impacts according to some strategy determined by how the County wishes to manage growth. Solutions for impact problems depend on which growth strategy is selected and what additional resources are secured during the impact period. A monitoring program deals with the problems of data and projections uncertainty, while direct action is proposed to deal with the institutional problems of delay of the needed access road, timeing and location problems from the tax base mismatch, and lack of local planning capability

  1. Pathways to Mexico’s climate change mitigation targets: A multi-model analysis

    Veysey, Jason; Octaviano, Claudia; Calvin, Katherine; Martinez, Sara Herreras; Kitous, Alban; McFarland, James; Zwaan, Bob van der

    2016-01-01

    Mexico’s climate policy sets ambitious national greenhouse gas (GHG) emission reduction targets—30% versus a business-as-usual baseline by 2020, 50% versus 2000 by 2050. However, these goals are at odds with recent energy and emission trends in the country. Both energy use and GHG emissions in Mexico have grown substantially over the last two decades. We investigate how Mexico might reverse current trends and reach its mitigation targets by exploring results from energy system and economic models involved in the CLIMACAP-LAMP project. To meet Mexico’s emission reduction targets, all modeling groups agree that decarbonization of electricity is needed, along with changes in the transport sector, either to more efficient vehicles or a combination of more efficient vehicles and lower carbon fuels. These measures reduce GHG emissions as well as emissions of other air pollutants. The models find different energy supply pathways, with some solutions based on renewable energy and others relying on biomass or fossil fuels with carbon capture and storage. The economy-wide costs of deep mitigation could range from 2% to 4% of GDP in 2030, and from 7% to 15% of GDP in 2050. Our results suggest that Mexico has some flexibility in designing deep mitigation strategies, and that technological options could allow Mexico to achieve its emission reduction targets, albeit at a cost to the country. - Highlights: • We explore paths to deep mitigation for Mexico (50% cut in GHG emissions by 2050). • We present results from six models and compare them with Mexican climate policy. • We find a range of potential paths and costs, implying options for policy makers. • An important commonality between the paths is a decarbonized electricity supply. • Estimated mitigation costs vary but are higher than official published estimates.

  3. Tourism and climate change: socioeconomic implications, mitigation and adaptation measures

    Utsab Bhattarai

    2015-06-01

    Full Text Available The relationship between tourism and changing climate has been discussed and studied for a relatively long time in tourism research. Over the past 15 years, more focused studies have begun to appear, and especially recently, the issue of adaptation and mitigation has been emphasized as an urgent research need in tourism and climate change studies. This paper is based on the review of selected articles which discuss the several forms of tourism and climate change and provide recommendations for mitigation and adaptation measures. This review paper assesses the impacts of climate change on the popular forms of tourism such as; mountain tourism, wildlife tourism, adventure tourism, sun/sand tourism; last chance tourism, and describes the extent of tourism vulnerabilities and their implications. The paper concludes that the appropriate adaptation and mitigation measures have to be followed to minimize the risk of climate change while trying to save all forms of tourism. The initiative of this article is to present an overview of the existing literature on the relationship between tourism and climate change in order to establish the current state of corporate and institutional responses within the tourism industry and to set out an agenda for future research. The currency of the review is evident given the recent surge in popular discussion on climate change and its effects on tourism, and the appearance of a broad and disparate array of studies on this topic.

  4. The role of China in mitigating climate change

    Paltsev, Sergey; Morris, Jennifer; Cai, Yongxia; Karplus, Valerie; Jacoby, Henry

    2012-01-01

    We explore short- and long-term implications of several energy scenarios of China's role in efforts to mitigate global climate risk. The focus is on the impacts on China's energy system and GDP growth, and on global climate indicators such as greenhouse gas concentrations, radiative forcing, and global temperature change. We employ the MIT Integrated Global System Model (IGSM) framework and its economic component, the MIT Emissions Prediction and Policy Analysis (EPPA) model. We demonstrate that China's commitments for 2020, made during the UN climate meetings in Copenhagen and Cancun, are reachable at very modest cost. Alternative actions by China in the next 10 years do not yield any substantial changes in GHG concentrations or temperature due to inertia in the climate system. Consideration of the longer-term climate implications of the Copenhagen-type of commitments requires an assumption about policies after 2020, and the effects differ drastically depending on the case. Meeting a 2 °C target is problematic unless radical GHG emission reductions are assumed in the short-term. Participation or non-participation of China in global climate architecture can lead by 2100 to a 200–280 ppm difference in atmospheric GHG concentration, which can result in a 1.1 °C to 1.3 °C change by the end of the century. We conclude that it is essential to engage China in GHG emissions mitigation policies, and alternative actions lead to substantial differences in climate, energy, and economic outcomes. Potential channels for engaging China can be air pollution control and involvement in sectoral trading with established emissions trading systems in developed countries. - Highlights: ► It is essential to engage China in GHG emissions mitigation policies. ► China's mitigation actions proposed for 2015 and 2020 are reachable at modest costs. ► Meeting 2 °C target is problematic without radical GHG emissions reductions.

  5. Economy of climatic change. From mitigation to adaptation policies

    Rousset, N.

    2012-01-01

    Climate change adaptation policies are the subject of this thesis. It has been showed that the United Nations Framework Convention on Climate Change (1992) and the response strategies construction are characteristic of a pollutionist approach. This approach led to envision the question of climate change as a classic pollution and environment issue. As a result, this approach has generated a double bias to the disadvantage of adaptation compared to mitigation policies: adaptation has been confined in a secondary and marginal role in climate policies structuring, and with an inoperative conceptual and methodological framework for its implementation. The thesis proposes a deconstruction of this climate change conceptualization. Moreover, the major limits that characterize mitigation policies call into question the predominance given to them in climate policies construction. The 'pollutionist' approach deconstruction allows at first to show that adaptation policies definition and operationalization need to go beyond (i) the standard analytic framework of climate policies and, (ii) the climate change conceptualization as a classic pollution and environment management issue. The thesis then argues that adaptation has to be integrated in development promoting policies, which means that adaptation needs to be conceptualized no longer as an ad hoc management of pollution effects issue, but as a development issue. Whether in the proper context of adaptation policies, or more largely of climate policies, the thesis leaves open the questions of the viability, but also of the organization and financing modalities, of a climate regime which fits within development promoting.

  6. Soil mapping and processes models to support climate change mitigation and adaptation strategies: a review

    Muñoz-Rojas, Miriam; Pereira, Paulo; Brevik, Eric; Cerda, Artemi; Jordan, Antonio

    2017-04-01

    As agreed in Paris in December 2015, global average temperature is to be limited to "well below 2 °C above pre-industrial levels" and efforts will be made to "limit the temperature increase to 1.5 °C above pre-industrial levels. Thus, reducing greenhouse gas emissions (GHG) in all sectors becomes critical and appropriate sustainable land management practices need to be taken (Pereira et al., 2017). Mitigation strategies focus on reducing the rate and magnitude of climate change by reducing its causes. Complementary to mitigation, adaptation strategies aim to minimise impacts and maximize the benefits of new opportunities. The adoption of both practices will require developing system models to integrate and extrapolate anticipated climate changes such as global climate models (GCMs) and regional climate models (RCMs). Furthermore, integrating climate models driven by socio-economic scenarios in soil process models has allowed the investigation of potential changes and threats in soil characteristics and functions in future climate scenarios. One of the options with largest potential for climate change mitigation is sequestering carbon in soils. Therefore, the development of new methods and the use of existing tools for soil carbon monitoring and accounting have therefore become critical in a global change context. For example, soil C maps can help identify potential areas where management practices that promote C sequestration will be productive and guide the formulation of policies for climate change mitigation and adaptation strategies. Despite extensive efforts to compile soil information and map soil C, many uncertainties remain in the determination of soil C stocks, and the reliability of these estimates depends upon the quality and resolution of the spatial datasets used for its calculation. Thus, better estimates of soil C pools and dynamics are needed to advance understanding of the C balance and the potential of soils for climate change mitigation. Here

  7. Advance strategy for climate change adaptation and mitigation in cities

    2017-12-01

    An on-going 5-yr project financially supported by the Ministry of Environment, Japan, has been carried out to specifically address the issue of prescribing appropriate adaptation and mitigation measures to climate change in cities. Entitled "Case Study on Mitigation and Local Adaptation to Climate Change in an Asian Megacity, Jakarta", the project's relevant objectives is to develop a research framework that can consider both urbanization and climate change with the main advantage of being readily implementable for all cities around the world. The test location is the benchmark city, Jakarta, Indonesia, with the end focus of evaluating the benefits of various mitigation and adaptation strategies in Jakarta and other megacities. The framework was designed to improve representation of urban areas when conducting climate change investigations in cities; and to be able to quantify separately the impacts of urbanization and climate change to all cities globally. It is comprised of a sophisticated, top-down, multi-downscaling approach utilizing a regional model (numerical weather model) and a microscale model (energy balance model and CFD model), with global circulation models (GCM) as input. The models, except the GCM, were configured to reasonably consider land cover, urban morphology, and anthropogenic heating (AH). Equally as important, methodologies that can collect and estimate global distribution of urban parametric and AH datasets are continually being developed. Urban growth models, climate scenario matrices that match representative concentration pathways with shared socio-economic pathways, present distribution of socio-demographic indicators such as population and GDP, existing GIS datasets of urban parameters, are utilized. From these tools, future urbanization (urban morphological parameters and AH) can be introduced into the models. Sensitivity using various combinations of GCM and urbanization can be conducted. Furthermore, since the models utilize

  8. Climate change, mitigation and adaptation with uncertainty and learning

    Ingham, Alan; Ma Jie; Ulph, Alistair

    2007-01-01

    One of the major issues in climate change policy is how to deal with the considerable uncertainty that surrounds many of the elements. Some of these uncertainties will be resolved through the process of further research. This process of learning raises a crucial timing question: should society delay taking action in anticipation of obtaining better information, or should it accelerate action, because we might learn that climate change is much more serious than expected. Much of the analysis to date has focussed on the case where the actions available to society are just the mitigation of emissions, and where there is little or no role for learning. We extend the analysis to allow for both mitigation and adaptation. We show that including adaptation weakens the effect of the irreversibility constraint and so, for this model, makes it more likely that the prospect of future learning should lead to less action now to deal with climate change. We review the empirical literature on climate change policy with uncertainty, learning, and irreversibility, and show that to date the effects on current policy are rather small, though this may reflect the particular choice of models employed

    Rasiah, Rajah; Ahmed, Adeel; Al-Amin, Abul Quasem; Chenayah, Santha

    2017-01-01

    This paper analyses empirically the optimal climate change mitigation policy of Malaysia with the business as usual scenario of ASEAN to compare their environmental and economic consequences over the period 2010-2110. A downscaling empirical dynamic model is constructed using a dual multidisciplinary framework combining economic, earth science, and ecological variables to analyse the long-run consequences. The model takes account of climatic variables, including carbon cycle, carbon emission, climatic damage, carbon control, carbon concentration, and temperature. The results indicate that without optimal climate policy and action, the cumulative cost of climate damage for Malaysia and ASEAN as a whole over the period 2010-2110 would be MYR40.1 trillion and MYR151.0 trillion, respectively. Under the optimal policy, the cumulative cost of climatic damage for Malaysia would fall to MYR5.3 trillion over the 100 years. Also, the additional economic output of Malaysia will rise from MYR2.1 billion in 2010 to MYR3.6 billion in 2050 and MYR5.5 billion in 2110 under the optimal climate change mitigation scenario. The additional economic output for ASEAN would fall from MYR8.1 billion in 2010 to MYR3.2 billion in 2050 before rising again slightly to MYR4.7 billion in 2110 in the business as usual ASEAN scenario.

  15. Bioenergy, Land Use Change and Climate Change Mitigation. Report for Policy Advisors and Policy Makers

    Berndes, Goran [Chalmers Univ. of Technology (Sweden); Bird, Nell [Joanneum Research (Austria); Cowle, Annette [National Centre for Rural Greenhouse Gas Research (Australia)

    2010-07-01

    The report addresses a much debated issue - bioenergy and associated land use change, and how the climate change mitigation from use of bioenergy can be influenced by greenhouse gas emissions arising from land use change. The purpose of the report was to produce an unbiased, authoritative statement on this topic aimed especially at policy advisors and policy makers.

  16. Options for change in the NHS consultant contract.

    Clarke, R W; Gray, C

    The lead negotiators for the management and consultant sides in an NHS trust in northern England responded to debate in their trust about consultant contracts by offering to research the attitudes of their peers towards a variety of contract options. The options tested included the current contract; models already examined in the trust and elsewhere, such as time sensitive and mild performance related contracts; and some more radical and speculative possibilities, including consultants franchising their services to the trust. Beyond the predictable conclusion that consultants would prefer no change while managers desired it, a time sensitive contract emerged as having potential for successful negotiation. On the other hand, neither consultants nor managers favoured a strict performance related contract or a fee for service contract. There was a strong similarity of opinion between the two groups on the relative salary values of the options, though the consultants consistently priced these higher than the managers.

  17. Transport policies related to climate change mitigation: the case of Denmark

    Vad Mathiesen, B.; Kappel, J.

    2013-03-15

    This report presents the Danish national policies on reducing the emissions of greenhouse gasses and reducing Denmark's dependency on fossil fuels in the transport sector, as well as some of the results of the policies. Systematic focus on efficient transport and climate mitigation started in 2008 and 2009 with a change - not only in the wording and in the political visions - but also in the actual prioritisation of investments and policies to a very large extent. In March 2012 another milestone was set by the Government, to have Denmark based on 100% renewable energy in 2050. This entails large challenges for the transport sectors, which has not yet been systematically analysed from any Governmental body. In this report we list projects which have done so. The first chapter describes policies and initiatives of international relevance within climate mitigation. The following chapters explain in further debt these policies and their effects as well as a number of additional policies and initiatives related to climate mitigation and transport. The private sector and local government has proven important in connection with an efficient transport sector. Hence selected local and regional projects and their results are introduced as well. To provide an overview of current trends, related scientific projects and other analyses on climate change mitigation and transport are given in the report. The references used in this report can also serve as a source of data and inspiration for the reader. This report is prepared as one of many inputs to the analyses conducted in The Swedish Government's Commission on fossil-free road transport. The task of this Commission is to: ''review alternative developments of fuels and vehicles for fossil-free road transport, to consider measures and policy options that would enable the Swedish road transport system to become climate neutral by 2050, and to propose intermediate emission reduction targets for years such as

  18. China's strategy for energy development and climate change mitigation

    He Jiankun; Yu Zhiwei; Zhang Da

    2012-01-01

    In recent years, China has made great efforts in energy saving and carbon emission reduction by pushing forward domestic sustainable development along with global climate change mitigation. The efforts have paid off with a dramatic decrease in carbon intensity. Nevertheless, China is still confronted with tough challenges in emission control due to the fast pace of industrialization, large total historical emission and high growth rate of emissions. Therefore, China should give priority to energy saving by improving energy efficiency and sectoral structure adjustment and upgrade, and develop sustainable and renewable energy to optimize energy mix and its carbon content. China should continue to regard significant reduction of energy intensity and carbon intensity as the main objective in the near future, strive to achieve peak emissions around 2030, and realize a relatively sharp emissions reduction by 2050 in order to address climate change to meet the goal of making the warming less than 2°. During the 12th Five Year Plan (FYP), China will further strengthen measures to control the amount of energy consumption, establish a statistics, accounting and evaluation system of carbon emissions, and promote a market-based carbon emissions trading mechanism to facilitate the low-carbon transformation of China's economy. - Highlights: ► This paper studies China's strategy for energy development and climate change mitigation. ► We suggest that China should focus on reducing the energy intensity and carbon intensity of GDP, and optimization of energy mix in the near term. ► In the long term, China should achieve the peak emission around 2030, and realize a relative sharp emission reduction by 2050. ► The paper also concludes some important measures which China should take during the 12th Five-Year-Plan (2011–2015).

  19. Urban Planning and Climate Change: Adaptation and Mitigation Strategies

    Fulvia Pinto

    2014-05-01

    Full Text Available Climate change is a current phenomenon: the temperatures rise, rainfall patterns are changing, glaciers melt and the average global sea level is rising. It is expected that these changes will continue and that the extreme weather events, such as floods and droughts, will become more frequent and intense. The impact and vulnerability factors for nature, for the economy and for our health are different, depending on the territorial, social and economic aspects. The current scientific debate is focused on the need to formulate effective policies for adaptation and mitigation to climate change. The city plays an important role in this issue: it emits the most greenhouse gas emissions (more than 60% of the world population currently lives in urban areas and the city is more exposed and vulnerable to the impacts of climate change. Urban planning and territorial governance play a crucial role in this context: the international debate on the sustainability of urban areas is increasing. It’s necessary to adapt the tools of building regulations to increase the quality of energy - environment of the cities.

  20. A review of accidents, prevention and mitigation options related to hazardous gases

    Fthenakis, V.M.

    1993-05-01

    Statistics on industrial accidents are incomplete due to lack of specific criteria on what constitutes a release or accident. In this country, most major industrial accidents were related to explosions and fires of flammable materials, not to releases of chemicals into the environment. The EPA in a study of 6,928 accidental releases of toxic chemicals revealed that accidents at stationary facilities accounted for 75% of the total number of releases, and transportation accidents for the other 25%. About 7% of all reported accidents (468 cases) resulted in 138 deaths and 4,717 injuries ranging from temporary respiratory problems to critical injuries. In-plant accidents accounted for 65% of the casualties. The most efficient strategy to reduce hazards is to choose technologies which do not require the use of large quantities of hazardous gases. For new technologies this approach can be implemented early in development, before large financial resources and efforts are committed to specific options. Once specific materials and options have been selected, strategies to prevent accident initiating events need to be evaluated and implemented. The next step is to implement safety options which suppress a hazard when an accident initiating event occurs. Releases can be prevented or reduced with fail-safe equipment and valves, adequate warning systems and controls to reduce and interrupt gas leakage. If an accident occurs and safety systems fail to contain a hazardous gas release, then engineering control systems will be relied on to reduce/minimize environmental releases. As a final defensive barrier, the prevention of human exposure is needed if a hazardous gas is released, in spite of previous strategies. Prevention of consequences forms the final defensive barrier. Medical facilities close by that can accommodate victims of the worst accident can reduce the consequences of personnel exposure to hazardous gases

  1. Promoting interactions between local climate change mitigation, sustainable energy development, and rural development policies in Lithuania

    Streimikiene, Dalia; Baležentis, Tomas; Kriščiukaitienė, Irena

    2012-01-01

    Lithuania has developed several important climate change mitigation policy documents however there are no attempts in Lithuania to develop local climate change mitigation policies or to decentralize climate change mitigation policy. Seeking to achieve harmonization and decentralization of climate change mitigation and energy policies in Lithuania the framework for local climate change mitigation strategy need to be developed taking into account requirements, targets and measures set in national climate change mitigation and energy policy documents. The paper will describe how national climate change mitigation and energy policies can be implemented via local energy and climate change mitigation plans. The aim of the paper is to analyze the climate change mitigation policy and its relationship with policies promoting sustainable energy development in Lithuania and to present a framework for local approaches to climate change mitigation in Lithuania, in the context of the existing national and supra-national energy, climate change, and rural development policies. - Highlights: ► The framework for local energy action plans is offered. ► The structural support possibilities are assessed with respect to the Lithuanian legal base. ► The proposals are given for further promotion of sustainable energy at the local level.

  2. Policies for accelerating access to clean energy, improving health, advancing development, and mitigating climate change.

    2007-10-06

    The absence of reliable access to clean energy and the services it provides imposes a large disease burden on low-income populations and impedes prospects for development. Furthermore, current patterns of fossil-fuel use cause substantial ill-health from air pollution and occupational hazards. Impending climate change, mainly driven by energy use, now also threatens health. Policies to promote access to non-polluting and sustainable sources of energy have great potential both to improve public health and to mitigate (prevent) climate disruption. There are several technological options, policy levers, and economic instruments for sectors such as power generation, transport, agriculture, and the built environment. However, barriers to change include vested interests, political inertia, inability to take meaningful action, profound global inequalities, weak technology-transfer mechanisms, and knowledge gaps that must be addressed to transform global markets. The need for policies that prevent dangerous anthropogenic interference with the climate while addressing the energy needs of disadvantaged people is a central challenge of the current era. A comprehensive programme for clean energy should optimise mitigation and, simultaneously, adaption to climate change while maximising co-benefits for health--eg, through improved air, water, and food quality. Intersectoral research and concerted action, both nationally and internationally, will be required.

  3. Adaptation to climate change in agriculture: evaluation of options

    Dolan, A.H.; Smit, B.; Skinner, M.W.; Bradshaw, B.; Bryant, C.R.

    2001-01-01

    Adaptation was defined as the responses by stakeholders to actual or expected climatic stimuli or their effects to reduce vulnerability to adverse impacts or damage potential, or to realize opportunities associated with climate change. Planned policy initiatives representing change in the agricultural system were discussed in this report. An evaluation of adaptation options needed to be carried out before one could determine which adaptations should be promoted or implemented. The overall merit, suitability, utility or appropriateness of potential adaptation strategies or measures were examined. One interesting methodology was the Multiple Criteria Evaluation (MCE), which is designed to assess alternatives using more than one criterion. The criteria selected for this evaluation were: effectiveness, economic efficiency, flexibility, institutional compatibility, farmer implementation, and independent benefits. A selection of three adaptation options was made to better illustrate the utility of the evaluation framework., as follows: crop diversification, adoption of irrigation, and increase use of crop insurance. 122 refs., 6 tabs., 6 figs

  4. CO_2-mitigation options for the offshore oil and gas sector

    Nguyen, Tuong-Van; Tock, Laurence; Breuhaus, Peter; Maréchal, François; Elmegaard, Brian

    2016-01-01

    Highlights: • The possibilities for reducing offshore CO_2-emissions, by CO_2-capture, waste heat recovery and electrification are assessed. • Multi-objective optimisation, process modelling, economic and environmental analyses are used for evaluating system designs. • A reduction of more than 15% of the total CO_2-emissions can be achieved for the present case study. • High sensitivity of the avoidance costs to the natural gas price and CO_2-tax. - Abstract: The offshore extraction of oil and gas is an energy-intensive process leading to the production of CO_2 and methane, discharged into the atmosphere, and of chemicals, rejected into the sea. The taxation of these emissions, in Norway, has encouraged the development of more energy-efficient and environmental-friendly solutions, of which three are assessed in this paper: (i) the implementation of waste heat recovery, (ii) the installation of a CO_2-capture unit and (iii) the platform electrification. A North Sea platform is taken as case study, and these three options are modelled, analysed and compared, using thermodynamic, economic and environmental indicators. The results indicate the benefits of all these options, as the total CO_2-emissions can be reduced by more than 15% in all cases, while the avoidance costs vary widely and are highly sensitive to the natural gas price and CO_2-tax.

  5. Climate Change: Seed Production and Options for Adaptation

    John G. Hampton

    2016-07-01

    Full Text Available Food security depends on seed security and the international seed industry must be able to continue to deliver the quantities of quality seed required for this purpose. Abiotic stress resulting from climate change, particularly elevated temperature and water stress, will reduce seed yield and quality. Options for the seed industry to adapt to climate change include moving sites for seed production, changing sowing date, and the development of cultivars with traits which allow them to adapt to climate change conditions. However, the ability of seed growers to make these changes is directly linked to the seed system. In the formal seed system operating in developed countries, implementation will be reasonably straight forward. In the informal system operating in developing countries, the current seed production challenges including supply failing to meet demand and poor seed quality will increase with changing climates.

  6. Climate change and groundwater: India's opportunities for mitigation and adaptation

    Shah, Tushaar

    2009-01-01

    For millennia, India used surface storage and gravity flow to water crops. During the last 40 years, however, India has witnessed a decline in gravity-flow irrigation and the rise of a booming 'water-scavenging' irrigation economy through millions of small, private tubewells. For India, groundwater has become at once critical and threatened. Climate change will act as a force multiplier; it will enhance groundwater's criticality for drought-proofing agriculture and simultaneously multiply the threat to the resource. Groundwater pumping with electricity and diesel also accounts for an estimated 16-25 million mt of carbon emissions, 4-6% of India's total. From a climate change point of view, India's groundwater hotspots are western and peninsular India. These are critical for climate change mitigation as well as adaptation. To achieve both, India needs to make a transition from surface storage to 'managed aquifer storage' as the center pin of its water strategy with proactive demand- and supply-side management components. In doing this, India needs to learn intelligently from the experience of countries like Australia and the United States that have long experience in managed aquifer recharge.

    Strong decreases in greenhouse gas emissions are required to meet the reduction trajectory resolved within the 2015 Paris Agreement. However, even these decreases will not avert serious stress and damage to life on Earth, and additional steps are needed to boost the resilience of ecosystems, safeguard their wildlife, and protect their capacity to supply vital goods and services. We discuss how well-managed marine reserves may help marine ecosystems and people adapt to five prominent impacts of climate change: acidification, sea-level rise, intensification of storms, shifts in species distribution, and decreased productivity and oxygen availability, as well as their cumulative effects. We explore the role of managed ecosystems in mitigating climate change by promoting carbon sequestration and storage and by buffering against uncertainty in management, environmental fluctuations, directional change, and extreme events. We highlight both strengths and limitations and conclude that marine reserves are a viable low-tech, cost-effective adaptation strategy that would yield multiple cobenefits from local to global scales, improving the outlook for the environment and people into the future.

  8. Renewable Energy Deployment as Climate Change Mitigation in Nigeria

    Olotu Yahaya

    2016-10-01

    Full Text Available The scientific evidence of climate change as a result of greenhouse gas emissions which causes ozone layer depletion is becoming increasingly obvious and clear. Findings revealed that energy from the fossil fuel is the major source of greenhouse emission which destroys the environment and makes it unhealthy for living beings. In Nigeria, conventional energy (oil and gas with gas flaring has the highest percentage of 52% and liquid fuel of 32% of carbon dioxide (CO2 respectively. This sector contributes revenue of over 70% to Nigeria’s economy and generates an average total 21.8% of greenhouse gas emission. In Nigeria, there is a much more potential for share renewables with 15.4% of total energy production and 8.6 % of energy consumption. In reality with global environmental concern, Nigeria’s carbon dioxide emissions have increased with energy production and consumption. The Integrated Renewable Energy Master Plan of 2008 projects a 26.7% renewable energy contribution to the Nigeria’s energy use and this is expected to reduce CO2 and greenhouse gas emissions at 38% by2025. Nigeria has not been playing significant role by reducing emissions of greenhouse gases. This paper highlights Nigeria’s climate change situation and penetration requirements for various renewable energy deployments as mitigating instrument for climate change towards healthy and productive environment.

  10. Identify: Improving industrial energy efficiency and mitigating global climate change

    Lazarus, M.; Hill, D.; Cornland, D.W.; Heaps, C.; Hippel, D. von; Williams, R.

    1997-07-01

    The use of energy in the industrial sectors of nations with both industrialized and developing economies will continue to be, a major source of greenhouse gas (GHG) emissions, particularly carbon dioxide. The patterns of industrial-sector energy use--energy provided primarily by the combustion of fossil fuels-have shifted both within the between countries in recent decades. Projections of future energy use and carbon-dioxide (CO{sub 2}) emissions suggest continued shifts in these patterns, as industrial production in developed countries stabilizes and declines, while industrial output in the developing world continues to expand. This expansion of industrial-sector activity and CO{sub 2} emissions in developing countries presents both a challenge and an opportunity. To seize this opportunity and contribute to international efforts to mitigate global climate change, the United National Industrial Development Organization (UNIDO) recently initiated a two-phase effort to help improve the efficiency of energy-intensive industries (iron and steel, chemicals, refining, paper and pulp, and cement) in developing countries. As part of the Phase I, the authors reviewed industrial sector scenarios and to initiated development of a software-based toolkit for identifying and assessing GHG mitigating technologies. This toolkit, called IDENTIFY, is comprised of a technology inventory and a companion economic analysis tool. In addition, UNIDO commissioned institutions in India, South Africa, and Argentina to review energy use patterns and savings opportunities in selected industries across nine developing countries, and contribute to the development of the IDENTIFY toolkit. UNIDO is now preparing to launch Phase 2, which will focus on full development and dissemination of the IDENTIFY toolkit through seminars and case studies around the world. This paper describes Phase 1 of the UNIDO project.

  11. Implications of small modular reactors for climate change mitigation

    Iyer, Gokul; Hultman, Nathan; Fetter, Steve; Kim, Son H.

    2014-01-01

    Achieving climate policy targets will require large-scale deployment of low-carbon energy technologies, including nuclear power. The small modular reactor (SMR) is viewed as a possible solution to the problems of energy security as well as climate change. In this paper, we use an integrated assessment model (IAM) to investigate the evolution of a global energy portfolio with SMRs under a stringent climate policy. Technology selection in the model is based on costs; we use results from previous expert elicitation studies of SMR costs. We find that the costs of achieving a 2 °C target are lower with SMRs than without. The costs are higher when large reactors do not compete for market share compared to a world in which they can compete freely. When both SMRs and large reactors compete for market share, reduction in mitigation cost is achieved only under advanced assumptions about SMR technology costs and future cost improvements. While the availability of SMRs could lower mitigation costs by a moderate amount, actual realization of these benefits would depend on the rapid up-scaling of SMRs in the near term. Such rapid deployment could be limited by several social, institutional and behavioral obstacles. - Highlights: • Costs of achieving a 2 °C target are lower with SMRs than without. • Costs are higher when large reactors do not compete for market share. • Under competition, cost is reduced only with advanced SMR technology. • Realization of benefits will depend on rapid near term up-scaling of SMRs

  12. The Climate Science Special Report: Perspectives on Climate Change Mitigation

    DeAngelo, B. J.

    2017-12-01

    This chapter of CSSR provides scientific context for key issues regarding the long-term mitigation of climate change. Policy analysis and recommendations are beyond the scope of CSSR. Limiting and stabilizing warming to any level implies that there is an upper limit to the cumulative amount of CO2 that can be added to the atmosphere. Eventually stabilizing the global temperature requires CO2 emissions to approach zero. For a 3.6°F (2°C) or any desired global mean temperature target, an estimated range of allowable cumulative CO2 emissions from the current period onward can be calculated. Accounting for the temperature effects of non-CO2 species, cumulative CO2 emissions are required to stay below about 800 GtC in order to provide a two-thirds likelihood of preventing 3.6°F (2°C) of warming, meaning approximately 230 GtC more could be emitted globally. Assuming global emissions follow the range between the RCP8.5 and RCP4.5 scenarios, emissions could continue for approximately two decades before this cumulative carbon threshold is exceeded. Meeting a 2.7°F (1.5°C) target implies much tighter constraints. Mitigation of non-CO2 species contributes substantially to near-term cooling benefits but cannot be relied upon for ultimate stabilization goals. Successful implementation of the first round of Nationally Determined Contributions associated with the Paris Agreement will provide some likelihood of meeting the long-term temperature goal of limiting global warming to "well below" 3.6°F (2°C) above preindustrial levels; the likelihood depends strongly on the magnitude of global emission reductions after 2030. If interest in geoengineering increases, interest will also increase in assessments of the technical feasibilities, costs, risks, co-benefits, and governance challenges of these additional measures, which are as yet unproven at scale.

  14. A climate for development. Climate change policy options for Africa

    Okoth-Ogendo, H.W.O.; Ojwang, J.B.

    1995-01-01

    The seriousness of the potential impacts of climate change on development in Africa is now well recognized within, and increasingly outside, scientific circles. The United Nations Framework Convention on Climate Change is a landmark in international environmental governance, providing a mechanism for exchange, negotiation and institution-building to re-direct development towards more efficient use of resources, especially energy. The message of 'A climate for Development' is that unless policy-makers fully understand both the international commitments made under the Convention and the essential national development priorities of their own countries, effective action on climate change is unlikely to be realized. The action needed, however, can at the same time stimulate capacity-building, planning and policy change which would strengthen the economic and ecological base of African countries. The climate change issue has hence brought us face to face with the urgency of the basic issues of sustainable development in Africa. The book discusses key issues that cut across all African countries, such as emissions and their impacts, financial resources and technology transfer for emissions abatement strategies. It then provides a sectoral analysis of greenhouse gas emissions and abatement options focusing on energy, industry, agriculture, forestry and transportation. The book concludes with guidelines for options which may be considered by African countries to ensure that climate change concerns are effectively dealt with in the context of their development priorities. 113 refs

  15. Developing a made-in-Canada climate change option

    Lakeman, B.

    2002-01-01

    A federal paper on Kyoto options served as a basis for this presentation. The author outlines the Alberta perspective on the federal options paper: (1) Alberta is impacted inequitably under all scenarios, (2) incomplete analysis, (3) export of Canadian capital, (4) open-ended liability, and (5) options need to reflect principles developed by Premiers and conveyed to Prime Minister in February. The principles for climate change action are: shared understanding of range of real costs, informed consultation, avoid competitive disadvantage, collaboration at all levels of government, no unreasonable share of the burden, encourage the use of new technology, Canadians need to be part of climate change solution, and focus on energy conservation and efficiency. The Alberta plan of action calls for a longer time frame and consultation with Albertans. With the topic of greenhouse gases (GHG), government leadership is required in the following areas: mandatory GHG reporting program, facilitate and negotiate agreements with key sectors, develop approach to emissions trading, and continue to pursue reductions in government operations. Some of the key initiatives include technology and innovation through the Alberta Energy Research Institute (AERI), build critical mass through partnerships, focus on clean hydrocarbon development and the transition to the hydrogen economy, carbon dioxide capture and storage, aggressive energy conservation, agricultural and forestry sinks, and adaptation. The consultation strategy is described. figs

    Kuwayama, Yusuke; Roeshot, Skyler; Krupnick, Alan; Richardson, Nathan; Mares, Jan

    2017-01-01

    We provide a critical review of existing research and information regarding the sources of risk associated with on-site shale gas and tight oil wastewater storage in the United States, the gaps that exist in knowledge regarding these risks, policy and technology options for addressing the risks, and the relative merits of those options. Specifically, we (a) identify the potential risks to human and ecological health associated with on-site storage of shale gas and tight oil wastewater via a literature survey and analysis of data on wastewater spills and regulatory violations, (b) provide a detailed description of government regulations or industry actions that may mitigate these risks to human and ecological health, and (c) provide a critical review of this information to help generate progress toward concrete action to make shale gas and tight oil development more sustainable and more acceptable to a skeptical public, while keeping costs down. - Highlights: • We review current research/information on shale gas and tight oil wastewater storage. • Pit overflows, tank overfills, and liner malfunctions are common spill causes. • Tanks lead to smaller and less frequent spills than pits, but are not a magic bullet. • State regulations for on-site oil and gas wastewater storage are very heterogeneous.

  17. Background document for climate change policy options in Northern Canada

    Newton, J.

    2001-01-01

    This paper presents an initial compilation of background material in support of the development of climate change policy options for the jurisdictions of Yukon, Northwest Territories and Nunavut in Northern Canada. While Northern Canada contributes only a small fraction of the world's greenhouse gas (GHG) emissions, scientists forecast changes in average annual temperatures to be among the highest in the world. The Northern Climate Exchange at Yukon College was created in March 2001 to address this issue and to help guide northerners in what they can do now and in the future. This paper includes an annotated bibliography of a total of 75 international, national, and territorial policy documents and major reference documents relevant to climate change issues. It is meant to be a resource for researchers, policy analysts and government officials developing policy options and implementing programs for Northern Canada. While each of the three northern territories are at a different stage in the evolution of their climate change activities, they are all striving to develop strategies and action plans and to initiate the implementation of those plans. It is recognized that many long-standing programs and initiatives, particularly in the areas of energy efficiency and alternate energy, will help northern jurisdictions address their climate change objectives. The three territories are cooperating to deliver their message to the federal government. 75 refs., 4 figs

    Risk and vulnerability assessment is an important component of an effective End-to-End Tsunami Early Warning System and therefore contributes significantly to disaster risk reduction. Risk assessment is a key strategy to implement and design adequate disaster prevention and mitigation measures. The knowledge about expected tsunami hazard impacts, exposed elements, their susceptibility, coping and adaptation mechanisms is a precondition for the development of people-centred warning structures, local specific response and recovery policy planning. The developed risk assessment and its components reflect the disaster management cycle (disaster time line) and cover the early warning as well as the emergency response phase. Consequently the components hazard assessment, exposure (e.g. how many people/ critical facilities are affected?), susceptibility (e.g. are the people able to receive a tsunami warning?), coping capacity (are the people able to evacuate in time?) and recovery (are the people able to restore their livelihoods?) are addressed and quantified. Thereby the risk assessment encompasses three steps: (i) identifying the nature, location, intensity and probability of potential tsunami threats (hazard assessment); (ii) determining the existence and degree of exposure and susceptibility to those threats; and (iii) identifying the coping capacities and resources available to address or manage these threats. The paper presents results of the research work, which is conducted in the framework of the GITEWS project and the Joint Indonesian-German Working Group on Risk Modelling and Vulnerability Assessment. The assessment methodology applied follows a people-centred approach to deliver relevant risk and vulnerability information for the purposes of early warning and disaster management. The analyses are considering the entire coastal areas of Sumatra, Java and Bali facing the Sunda trench. Selected results and products like risk maps, guidelines, decision support

  19. The southern Brazilian grassland biome: soil carbon stocks, fluxes of greenhouse gases and some options for mitigation.

    Pillar, V D; Tornquist, C G; Bayer, C

    2012-08-01

    The southern Brazilian grassland biome contains highly diverse natural ecosystems that have been used for centuries for grazing livestock and that also provide other important environmental services. Here we outline the main factors controlling ecosystem processes, review and discuss the available data on soil carbon stocks and greenhouse gases emissions from soils, and suggest opportunities for mitigation of climatic change. The research on carbon and greenhouse gases emissions in these ecosystems is recent and the results are still fragmented. The available data indicate that the southern Brazilian natural grassland ecosystems under adequate management contain important stocks of organic carbon in the soil, and therefore their conservation is relevant for the mitigation of climate change. Furthermore, these ecosystems show a great and rapid loss of soil organic carbon when converted to crops based on conventional tillage practices. However, in the already converted areas there is potential to mitigate greenhouse gas emissions by using cropping systems based on no soil tillage and cover-crops, and the effect is mainly related to the potential of these crop systems to accumulate soil organic carbon in the soil at rates that surpass the increased soil nitrous oxide emissions. Further modelling with these results associated with geographic information systems could generate regional estimates of carbon balance.

  20. The underestimated potential of solar energy to mitigate climate change

    Creutzig, Felix; Agoston, Peter; Goldschmidt, Jan Christoph; Luderer, Gunnar; Nemet, Gregory; Pietzcker, Robert C.

    2017-09-01

    The Intergovernmental Panel on Climate Change's fifth assessment report emphasizes the importance of bioenergy and carbon capture and storage for achieving climate goals, but it does not identify solar energy as a strategically important technology option. That is surprising given the strong growth, large resource, and low environmental footprint of photovoltaics (PV). Here we explore how models have consistently underestimated PV deployment and identify the reasons for underlying bias in models. Our analysis reveals that rapid technological learning and technology-specific policy support were crucial to PV deployment in the past, but that future success will depend on adequate financing instruments and the management of system integration. We propose that with coordinated advances in multiple components of the energy system, PV could supply 30-50% of electricity in competitive markets.

  1. Building synergies between climate change mitigation and energy poverty alleviation

    Ürge-Vorsatz, Diana; Tirado Herrero, Sergio

    2012-01-01

    Even though energy poverty alleviation and climate change mitigation are inextricably linked policy goals, they have remained as relatively disconnected fields of research inquiry and policy development. Acknowledging this gap, this paper explores the mainstream academic and policy literatures to provide a taxonomy of interactions and identify synergies and trade-offs between them. The most important trade-off identified is the potential increase in energy poverty levels as a result of strong climate change action if the internalisation of the external costs of carbon emissions is not offset by efficiency gains. The most significant synergy was found in deep energy efficiency in buildings. The paper argues that neither of the two problems – deep reductions in GHG emissions by mid-century, and energy poverty eradication – is likely to be solved fully on their own merit, while joining the two policy goals may provide a very solid case for deep efficiency improvements. Thus, the paper calls for a strong integration of these two policy goals (plus other key related benefits like energy security or employment), in order to provide sufficient policy motivation to mobilise a wide-scale implementation of deep energy efficiency standards. - Highlights: ► A taxonomy of interactions between climate change and energy poverty is offered. ► Energy poverty levels may increase as a result of strong climate change action. ► However, strong synergies are offered by deep improvements of energy efficiency. ► Access to modern energy carriers is a key requirement in developing countries. ► Sufficiently solving both problems requires the integration of policy goals.

  2. The Land Use and Cover Change in Miombo Woodlands under Community Based Forest Management and Its Implication to Climate Change Mitigation: A Case of Southern Highlands of Tanzania

    Z. J. Lupala

    2015-01-01

    Full Text Available In Tanzania, miombo woodland is the most significant forest vegetation with both ecological and socioeconomic importance. The vegetation has been threatened from land use and cover change due to unsustainable utilization. Over the past two decades, community based forest management (CBFM has been practiced to address the problem. Given the current need to mitigate global climate change, little is known on the influence of CBFM to the land use and cover change in miombo woodlands and therefore compromising climate change mitigation strategies. This study explored the dynamic of land use and covers change and biomass due to CBFM and established the implication to climate change mitigation. The study revealed increasing miombo woodland cover density with decreasing unsustainable utilization. The observed improvement in cover density and biomass provides potential for climate change mitigation strategies. CBFM also developed solidarity, cohesion, and social control of miombo woodlands illegal extraction. This further enhances permanence, reduces leakage, and increases accountability requirement for carbon credits. Collectively with these promising results, good land use plan at village level and introduction of alternative income generating activities can be among the best options to further reduce land use change and biomass loss in miombo woodlands.

    Land can be used in several ways to mitigate climate change, but especially under changing environmental conditions there may be implications for food prices. Using an integrated global system model, we explore the roles that these land-use options can play in a global mitigation strategy to stabilize Earth's average temperature within 2 °C of the preindustrial level and their impacts on agriculture. We show that an ambitious global Energy-Only climate policy that includes biofuels would likely not achieve the 2 °C target. A thought-experiment where the world ideally prices land carbon fluxes combined with biofuels (Energy+Land policy) gets the world much closer. Land could become a large net carbon sink of about 178 Pg C over the 21st century with price incentives in the Energy+Land scenario. With land carbon pricing but without biofuels (a No-Biofuel scenario) the carbon sink is nearly identical to the case with biofuels, but emissions from energy are somewhat higher, thereby results in more warming. Absent such incentives, land is either a much smaller net carbon sink (+37 Pg C - Energy-Only policy) or a net source (-21 Pg C - No-Policy). The significant trade-off with this integrated land-use approach is that prices for agricultural products rise substantially because of mitigation costs borne by the sector and higher land prices. Share of income spent on food for wealthier regions continues to fall, but for the poorest regions, higher food prices lead to a rising share of income spent on food.

  4. Climate Change Mitigation in a Sustainable World - Findings of the IPCC 4th Assessment Report

    Sims, R. E. H.

    2007-01-01

    The 4th Assessment Report on climate change of the Intergovernmental Panel on Climate Change (IPCC, 2007) has recently been completed. The fi rst report in the IPCC 4th Assessment series by Working Group I outlined the latest knowledge on Climate Science. The second by Working Group 2 covered the possibilities for Adaptation of ecosystems, glaciers preceding, sea level rising, droughts etc in various regions. This paper is based on the findings of Working Group III as presented in the recently published report Climate Change 2007: Mitigation of Climate Change. The 27 paragraph Summary for Policy Makers was approved sentence by sentence over 4 days in May 2007 by 120 government delegations in Bangkok, Thailand. The three short Summaries for Policy Makers (SPM), Synthesis report, and the three full reports can be found at www.ipcc.ch. In addition the short Synthesis Report across all three working groups is soon to be released. The report on Mitigation attempted to compile the latest scientific knowledge relating to low-carbon emitting technologies; assessed their costs and potentials for greenhouse gas (GHG) emission avoidance; evaluated their long term prospects out to 2100 for stabilising atmospheric GHGs; provided a detailed list of policy options; and discussed the opportunities for sustainable development and equity linked with GHG abatement. Over the 3 year writing and review process, the author of this paper was the co-ordinating lead author of the writing team for the Working Group III chapter on Energy Supply. Of the 13 chapters, this one received the greatest attention with over 5000 review comments that were each responded to, and with the sections on nuclear and renewable energy receiving a major share of them. Since the 3rd Assessment Report (TAR) was published in 2001, the over-arching message now being delivered by Working Group III is a stronger but positive one: Action is required. The situation is urgent - but not beyond repair. Many energy

  5. Impacts on Canadian Competitiveness of International Climate Change Mitigation

    Christopher Holling

    1998-06-01

    Full Text Available This article summarizes and provides additional perspective on a study that contributes to the growing body of analyses of the costs of limiting greenhouse gas emissions. The study estimates the economic costs to Canada of six planning scenarios. Four of these scenarios involve the use of tradable emission permits and two involved a carbon tax. In each case, the mechanism's target is to stabilize greenhouse gas emissions at some percentage of 1990 levels (100% or 90% by either 2010 or 2015. Policies that impose greater constraints on carbon dioxide emissions lead to higher economic costs in terms of foregone output. These costs, however, vary for the same objective, depending on the mechanism chosen and the economic assumptions made. In one typical scenario, in which tradable emission permits are used to achieve stabilization at 1990 levels by 2010, GDP is depressed from the "business-as-usual" scenario by about 2% for the first decade, after which it recovers to business-as-usual levels. Generally, for all scenarios, the economic impact of climate change mitigation imposes a transition cost on the economy, but the long-term productive capacity of the economy is not significantly affected.

    Land-use change, mainly the conversion of tropical forests to agricultural land, is a massive source of carbon emissions and contributes substantially to global warming. Therefore, mechanisms that aim to reduce carbon emissions from deforestation are widely discussed. A central challenge is the avoidance of international carbon leakage if forest conservation is not implemented globally. Here, we show that forest conservation schemes, even if implemented globally, could lead to another type of carbon leakage by driving cropland expansion in non-forested areas that are not subject to forest conservation schemes (non-forest leakage). These areas have a smaller, but still considerable potential to store carbon. We show that a global forest policy could reduce carbon emissions by 77 Gt CO2, but would still allow for decreases in carbon stocks of non-forest land by 96 Gt CO2 until 2100 due to non-forest leakage effects. Furthermore, abandonment of agricultural land and associated carbon uptake through vegetation regrowth is hampered. Effective mitigation measures thus require financing structures and conservation investments that cover the full range of carbon-rich ecosystems. However, our analysis indicates that greater agricultural productivity increases would be needed to compensate for such restrictions on agricultural expansion.

  8. Inventory of gases of greenhouse effect and mitigation options for Colombia

    Academia colombiana de ciencias exactas fisicas y naturales

    1998-01-01

    In the last years, the possibility of a global heating due to the emissions of greenhouse gases has become a true concern for the international scientific community. As a result of it created the IPCC (Intergovernmental Panel on Climate Change) and the agreement mark was approved about the climatic change of the United Nations (UNFCCC) that was subscribed by the countries in 1992 in Rio de Janeiro city in Brazil. The objective of the agreement is the stabilization of the concentrations of the gases of GEI effect in the atmosphere at a level that allows avoiding interferences anthropogenic dangerous for the climatic system. It is sought to reach this level inside a sufficiently long term to allow the natural adaptation from the ecosystems to the climatic change, guaranteeing this way the production of foods and the sustainable development. The government from Colombia subscribed the agreement mark about the climatic change of the United Nations (UNFCCC) in 1992 and the congress of the republic ratified it in 1995. The signatory countries of the agreement commit to elaborate and to publish national inventories of anthropogenic emissions of gases of greenhouse effect as well as to develop plans to reduce or to control the emissions

  10. Policy progress in mitigation of climate change in Taiwan

    Hwang, Jenn Jiang; Chang, Wei Ru

    2011-01-01

    To make an active contribution to the global effort in mitigation of climate change, Taiwan government has implemented the 'Frameworks for Sustainable Energy Policy-An Energy-Saving and Carbon-Reduction Action Plan' in June 2008. It has made a commitment of a stepwise reduction of nationwide greenhouse gas (GHG) emissions, which returns the nationwide GHG emission to 2008 levels by 2020, then reduces to 2000 levels by 2025, and finally cuts 50% of 2000 levels by 2050. The fundamental strategy is to reduce the GHG emission under acceptable economic development and energy security to achieve generation-spanning triple-win in energy, environment and economy. The major policy instruments such as 'Statute for Renewable Energy Development', 'GHG Reduction Law (draft),' 'Regulation for Energy Tax (draft),' and 'Energy Management Act' have been either implemented or scheduled for legislative reviewing. The purpose of this paper is to present an updated review of the outcomes of GHG emission reduction in Taiwan. In addition, the progress and priority of policy instruments in GHG emission reduction are analyzed as well. - Research highlights: →Taiwan has made a commitment of stepwise targets of GHG emission reduction to contribute to the global efforts in combating climate change in 2008. →The near-term target returns the nationwide GHG emissions back to 2008 levels during years of 2016-2020. Then, emission levels are cut to 2000 levels by 2025, and finally 50% of 2000 levels by 2050. →In addition to finish legislative review of the 'GHG Reduction Act', Taiwan has prepared a comprehensive action plan to reduce the national GHG emissions, involving improvement of the efficiency in energy use, development of the sustainable energy, and taxation of carbon on fossils.

  12. Narrative scenario development based on cross-impact analysis for the evaluation of global-warming mitigation options

    Hayashi, Ayami; Tokimatsu, Koji; Yamamoto, Hiromi; Mori, Shunsuke

    2006-01-01

    Social, technological, economic and environmental issues should be considered comprehensively for the evaluation of global-warming mitigation options. Existing integrated assessment models include assessment of quantitative factors; however, these models do not explicitly consider interactions among qualitative factors in the background - for example, introductions of nuclear power stations interact with social acceptability. In this paper, we applied a technological forecasting method - the cross-impact method - which explicitly deals with the relationships among relevant factors, and we then developed narrative scenarios having consistency with qualitative social contexts. An example of developed scenarios in 2050, assuming the global population and the gross domestic product are the same as those of the A1 scenario of the IPCC Special Report on Emissions Scenarios, tells us that: (1) the Internet will be extensively used in all regions; (2) the global unified market will appear; (3) regional cultures will tend to converge; (4) long-term investments (of more than 30 years) will become difficult and therefore nuclear-power stations will not increase so remarkably; (5) the self-sufficient supply and diversification of primary energy sources will not progress so rapidly; and (6) due to the widespread use of the Internet, people will be more educated in global environmental issues and environmental costs will be more socially acceptable

  13. Sustainability of arsenic mitigation interventions – an evaluation of different alternative safe drinking water options provided in Matlab, an arsenic hot spot in Bangladesh

    MOHAMMED eHOSSAIN

    2015-05-01

    Full Text Available The wide spread occurrence of geogenic arsenic (As in Bangladesh groundwater drastically reduced the safe water access across the country. Since its discovery in 1993, different mitigation options tested at household and community scale have resulted in limited success. In an arsenic hotspot of southeastern Bangladesh, 841 arsenic removal filter (ARF, 190 surface water filter membrane, 23 pond sand filter (PSF, 147 rain water harvester (RWH and 59 As-safe tubewell were distributed among the severely exposed population by AsMat, a Sida supported project. After three-four years of providing these safe water options, this study was carried out during 2010-2011 for performance analysis of these options, in terms of technical viability and effectiveness and thus to evaluate the preference of different options to the end users. Household and community based surveys were done to make an assessment of the current water use pattern as impact of the distributed options, overall condition of the options provided and to identify the reasons why these options are in use and/or abandoned. In total, 284 households were surveyed and information was collected for 23 PSF, 147 RWH and 59 tubewells. None of the filters was found in use. Among other options distributed, 13% of PSF, 40% RWH and 93% of tubewell were found functioning. In all cases, tubewells were found As-safe. About 89% of households are currently using tubewell water which was 58% before. Filter was abandoned for high cost and complicated maintenance. The use of RWH and PSF was not found user friendly and ensuring year round water quality is a big challenge. Arsenic-safe tubewell was found as a widely accepted option mainly because of its easy operation and availability of water, good water quality and negligible maintenance. This study validated tubewell as the most feasible option and holds significance for planning water supply projects, improving mitigation policy as well as developing awareness

  14. Mitigating Climate Change in the Arid Lands of Namibia

    Schneider, Martin B.; Sorensen, Marten

    2014-05-01

    Mitigating Climate Change in the Arid Lands of Namibia Namibia is the most arid country south of the Sahara, with scarce rainfall and perennial rivers only at its borders, > 80% of the area relies solely on groundwater. This has had devastating economic effects limiting opportunities for sustainable rural livelihoods that keep the population majority living below the World Bank poverty line (IFAD, 2013). A primary example of climatic variability which affects agrarian productivity is increased bush encroachment of Namibia's arid grazing land. The result has been a severe biodiversity loss, increased desertification and diminished water-use efficiency and underground water tables. Given these factors, Namibia's arid lands provide a unique opportunity to assess and test innovative / appropriate adaptation and mitigation strategies. Working toward sustainable management, restoration, and maintenance of balanced, resilient arid ecosystems in Namibia will also be a means to support and expand economic sectors incl. opportunities for job creation and potentially provide a model for similar arid regions. Main vegetation zones are: desert (46%), savannah (37%), and dry woodlands and forests (17%), i.e. management strategies currently used by rural communities. 2. Capture and assess cultural and gender dimensions of management strategies within stakeholder groups using participatory approaches. 3. Determine science-based alternatives for adaptive land management strategies and test their acceptability to local communities and within the current policy framework. 4. Integrate identified indigenous knowledge with appropriate science and new emerging technologies to develop a training toolkit of effective strategies relevant to all stakeholders. 5. Utilize training sessions, education workshops, curriculum revisions, and appropriate information and communication technologies (ICTs) including social media outlets to disseminate the toolkit strategies. 6.

    2010-01-01

    The post-2012 climate policy framework needs a global commitment to deep greenhouse gas emission cuts. This paper analyzes reaching ambitious emission targets up to 2050, either -10% or -50% from 1990 levels, and how the economic burden from mitigation efforts could be equitably shared between countries. The scenarios indicate a large low-cost mitigation potential in electricity and industry, while reaching low emission levels in international transportation and agricultural emissions might prove difficult. The two effort sharing approaches, Triptych and Multistage, were compared in terms of equitability and coherence. Both approaches produced an equitable cost distribution between countries, with least developed countries having negative or low costs and more developed countries having higher costs. There is, however, no definitive solution on how the costs should be balanced equitably between countries. Triptych seems to be yet more coherent than other approaches, as it can better accommodate national circumstances. Last, challenges and possible hindrances to effective mitigation and equitable effort sharing are presented. The findings underline the significance of assumptions behind effort sharing on mitigation potentials and current emissions, the challenge of sharing the effort with uncertain future allowance prices and how inefficient markets might undermine the efficiency of a cap-and-trade system.

  17. International energy technology collaboration and climate change mitigation. Case study 1. Concentrating Solar Power Technologies

    Philibert, C. [Energy and Environment Division, International Energy Agency IEA, Paris (France)

    2004-07-01

    Mitigating climate change and achieving stabilisation of greenhouse gas atmospheric concentrations will require deep reductions in global emissions of energy-related carbon dioxide emissions. Developing and disseminating new, low-carbon energy technology will thus be needed. Two previous AIXG papers have focused on possible drivers for such a profound technological change: Technology Innovation, Development and Diffusion, released in June 2003, and International Energy Technology Collaboration and Climate Change Mitigation, released in June 2004. The first of these papers assesses a broad range of technical options for reducing energy-related CO2 emissions. It examines how technologies evolve and the role of research and development efforts, alternative policies, and short-term investment decisions in making long-term options available. It considers various policy tools that may induce technological change, some very specific, and others with broader expected effects. Its overall conclusion is that policies specifically designed to promote technical change, or 'technology push', could play a critical role in making available and affordable new energy technologies. However, such policies would not be sufficient to achieve the Convention's objective in the absence of broader policies. First, because there is a large potential for cuts that could be achieved in the short run with existing technologies; and second, the development of new technologies requires a market pull as much as a technology push. The second paper considers the potential advantages and disadvantages of international energy technology collaboration and transfer for promoting technological change. Advantages of collaboration may consist of lowering R and D costs and stimulating other countries to invest in R and D; disadvantage may include free-riding and the inefficiency of reaching agreement between many actors. This paper sets the context for further discussion on the role of

  20. Climate change impacts and adaptation options for the Greek agriculture in 2021–2050: A monetary assessment

    E. Georgopoulou

    2017-01-01

    Full Text Available The paper presents a quantitative assessment of mid-term (2021–2050 climate change impacts on and potential adaptation options for selected crops in Greece that are of importance in terms of their share in national agricultural production and gross value added. Central points in the assessment are the monetary evaluation of impacts and the cost-benefit analysis of adaptation options. To address local variability in current and future climate conditions, analysis is spatially disaggregated into geographical regions using as an input downscaled results from climatic models. For some crops (cereals, vegetables, pulses, grapevines, changes in future agricultural yields are assessed by means of agronomic simulation models, while for the rest crops changes are assessed through regression models. The expected effects on crop yields of a number of potential adaptation options are also investigated through the same models, and the costs and benefits of these options are also quantitatively assessed. The findings indicate that climate change may create winners and losers depending on their agricultural activity and location, while adaptation can mitigate adverse effects of climate change under cost-effective terms.

    The three primary objectives of the conference, which was organized by the UNEP Collaborating Centre on Energy and Environment (UCCEE) in conjunction with the Environment Department of the World Bank, at Goa in India from May 4 to 6, 1998, were: 1) to share the GHG mitigation experiences from Asian developing countries; 2) to disseminate the standard methodological approach for mitigation analysis developed by UNEP and its applications in different countries; and 3) assess the role and efficacy of financial mechanisms and to, specifically, seek feedback on the Prototype Carbon Fund proposed by the World Bank. Follwing these objectives, the workshop presentations and discussions were structured in three parts. In the first part, participants from eleven Asian developing countries made presentations that were followed by discussions. The second part included the presentations by the experts from UCCEE, UNFCCC and other invited experts who presented the mitigation methodology and the issues and experiences relating to various co-operative implementation mechanisms. The third part included the presentations by the World Bank representatives on the Prototype Carbon Fund and the discussions on financial mechanisms. (EG)

    Abstract Climate change mitigation constitutes a social dilemma, a conflict between personal and collective outcomes. Behaviours that result in personal benefits (e.g. travelling quickly, conveniently and cheaply by plane) also result in a collective cost in the form of climate change. Behavioural theories and evidence suggest this social dilemma structure significantly influences behaviour. This thesis aims to understand how the social dilemma structure of climate change mitigation affect...

  3. Sensitivity of climate change mitigation estimates to assumptions about technical change

    Dowlatabadi, H.

    1998-01-01

    With greater certainty in anthropogenic influence on observed changes in climate there is increasing pressure for agreements to control emissions of greenhouse gases ([HOUGHTON]). While it is difficult to assess the appropriate level of mitigation, it has been argued that flexibility in meeting emission targets offers significant economic savings. Such flexibility can be exercised in terms of timing of mitigation (i.e. delay) or geographic location of the intervention (e.g. permit trading and Joint-Implementation). Much of this insight is based on standard models of technical change in energy supply and demand. However, standard model formulations rarely consider: (i) a link between the pattern of technical change and policy interventions; (ii) economies of learning; and (iii) technical progress in discovery and recovery of oil and gas. While there is evidence to support the importance of these factors in historic patterns of technical progress, the data necessary to calibrate internally consistent economic models of these phenomena have not been available. In this paper simple representations of endogenous and induced technical change have been used to explore the sensitivity of mitigation cost estimates to how technical change is represented in energy economics models. The scenarios involve control of CO 2 emissions to limit its concentration to no more than 550 ppm(v), starting in the year 2000, and delayed to 2025. This sensitivity analysis has revealed four robust insights: (i) If endogenous technical change is assumed, expected business as usual emissions are higher than otherwise estimated - nevertheless, while 25% greater CO 2 control is required for meeting the CO 2 concentration target, the cost of mitigation is 40% lower; (ii) If technical progress in oil and gas discovery and recovery is assumed, energy use and CO 2 emissions increase by 75% and 65%, respectively above the standard estimates; (iii) If the economies of learning exhibited in various

    The potential of forests and the forest sector to mitigate greenhouse gas (GHG) emissions is widely recognized, but challenging to quantify at a national scale. Forests and their carbon (C) sequestration potential are affected by management practices, where wood harvesting transfers C out of the forest into products, and subsequent regrowth allows further C sequestration. Here we determine the mitigation potential of the 2.3 × 106 km2 of Canada's managed forests from 2015 to 2050 using the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3), a harvested wood products (HWP) model that estimates emissions based on product half-life decay times, and an account of emission substitution benefits from the use of wood products and bioenergy. We examine several mitigation scenarios with different assumptions about forest management activity levels relative to a base case scenario, including improved growth from silvicultural activities, increased harvest and residue management for bioenergy, and reduced harvest for conservation. We combine forest management options with two mitigation scenarios for harvested wood product use involving an increase in either long-lived products or bioenergy uses. Results demonstrate large differences among alternative scenarios, and we identify potential mitigation scenarios with increasing benefits to the atmosphere for many decades into the future, as well as scenarios with no net benefit over many decades. The greatest mitigation impact was achieved through a mix of strategies that varied across the country and had cumulative mitigation of 254 Tg CO2e in 2030, and 1180 Tg CO2e in 2050. There was a trade-off between short-term and long-term goals, in that maximizing short-term emissions reduction could reduce the forest sector's ability to contribute to longer-term objectives. We conclude that (i) national-scale forest sector mitigation options need to be assessed rigorously from a systems perspective to avoid the development of

    Reducing emissions from deforestation and forest degradation in developing countries (REDD+) is regarded by its proponents as one of the more efficient and cost effective ways to mitigate climate change. There was further progress toward the implementation of this mechanism at the 16th Conference of Parties (COP) in Cancun in December 2010. Many countries in southern African, including South Africa, have not been integrated (do not participate) into the UN-REDD+ programme, probably due to their low forest cover and national rates of deforestation. This paper discusses the potential contribution of REDD+ activities to the South African Government's pledge of reducing national greenhouse gas (GHG) emissions by 34% below business as usual by 2020. A number of issues such as complex land tenure system, limited forest cover and other conflicting environmental issues present challenges for REDD+ in South Africa. Despite these genuine concerns, REDD+ remains a practical strategy to contribute to climate change mitigation for South Africa. The paper raises the need for development of a variety of emission reduction programmes – not only in the energy sector. The paper also assesses several national options and opportunities towards a working REDD+ mechanism. It concludes by identifying key mechanisms for moving forward to prepare for REDD+ actions in South Africa and raises the urgent need for national dialogue between stakeholders and institutions to evaluate the feasibility of making use of the mechanism in South Africa and the Southern African Development Cooperation (SADC) region. The paper further addresses possible synergies and conflicts between the national climate change and forestry policies towards REDD+ development. It suggests that REDD+ should be part of the national dialogue on policy to respond to climate change and should be integrated into the national flagship programmes that the national climate change white paper seeks to implement.

  6. Climate change and biological invasions: evidence, expectations, and response options.

    Hulme, Philip E

    2017-08-01

    A changing climate may directly or indirectly influence biological invasions by altering the likelihood of introduction or establishment, as well as modifying the geographic range, environmental impacts, economic costs or management of alien species. A comprehensive assessment of empirical and theoretical evidence identified how each of these processes is likely to be shaped by climate change for alien plants, animals and pathogens in terrestrial, freshwater and marine environments of Great Britain. The strongest contemporary evidence for the potential role of climate change in the establishment of new alien species is for terrestrial arthropods, as a result of their ectothermic physiology, often high dispersal rate and their strong association with trade as well as commensal relationships with human environments. By contrast, there is little empirical support for higher temperatures increasing the rate of alien plant establishment due to the stronger effects of residence time and propagule pressure. The magnitude of any direct climate effect on the number of new alien species will be small relative to human-assisted introductions driven by socioeconomic factors. Casual alien species (sleepers) whose population persistence is limited by climate are expected to exhibit greater rates of establishment under climate change assuming that propagule pressure remains at least at current levels. Surveillance and management targeting sleeper pests and diseases may be the most cost-effective option to reduce future impacts under climate change. Most established alien species will increase their distribution range in Great Britain over the next century. However, such range increases are very likely be the result of natural expansion of populations that have yet to reach equilibrium with their environment, rather than a direct consequence of climate change. To assess the potential realised range of alien species will require a spatially explicit approach that not only

    Anthropogenic climate change and the mitigation strategies aimed to attenuate it are both issues of great importance for human rights, public health, and socioeconomic equity. To understand these concerns and to better inform policy and strategic action it is critical to explore: 1) the disparities in the costs and benefits of climate shifts; 2) the abilities of different populations to adapt to these shifts; and 3) the social and health equity dimensions of the climate change mitigation stra...

  10. Public perceptions about climate change mitigation in British Columbia's forest sector

    Hagerman, Shannon; Kozak, Robert; Hoberg, George

    2018-01-01

    The role of forest management in mitigating climate change is a central concern for the Canadian province of British Columbia. The successful implementation of forest management activities to achieve climate change mitigation in British Columbia will be strongly influenced by public support or opposition. While we now have increasingly clear ideas of the management opportunities associated with forest mitigation and some insight into public support for climate change mitigation in the context of sustainable forest management, very little is known with respect to the levels and basis of public support for potential forest management strategies to mitigate climate change. This paper, by describing the results of a web-based survey, documents levels of public support for the implementation of eight forest carbon mitigation strategies in British Columbia’s forest sector, and examines and quantifies the influence of the factors that shape this support. Overall, respondents ascribed a high level of importance to forest carbon mitigation and supported all of the eight proposed strategies, indicating that the British Columbia public is inclined to consider alternative practices in managing forests and wood products to mitigate climate change. That said, we found differences in levels of support for the mitigation strategies. In general, we found greater levels of support for a rehabilitation strategy (e.g. reforestation of unproductive forest land), and to a lesser extent for conservation strategies (e.g. old growth conservation, reduced harvest) over enhanced forest management strategies (e.g. improved harvesting and silvicultural techniques). We also highlighted multiple variables within the British Columbia population that appear to play a role in predicting levels of support for conservation and/or enhanced forest management strategies, including environmental values, risk perception, trust in groups of actors, prioritized objectives of forest management and socio

    Smith, P; Olesen, Jørgen E

    2010-01-01

    There is a very significant, cost effective greenhouse gas (GHG) mitigation potential in agriculture. The annual mitigation potential in agriculture is estimated to be 4200, 2600 and 1600 Mt CO2 equiv/yr at C prices of 100, 50 and 20 US$/t CO2 equiv, respectively. The value of GHG mitigated each...... year is equivalent to 420 000, 130 000 and 32 000 million US$/yr for C prices of 100, 50 and 20 US$/t CO2 equiv, respectively. From both the mitigation and economic perspectives, we cannot afford to miss out on this mitigation potential. The challenge of agriculture within the climate change context...... of the agroecosystem in some way. This often not only affects the GHG emissions but also the soil properties and nutrient cycling.

    The Paris Agreement of the United Nation Framework Convention on Climate Change calls for a balance of anthropogenic greenhouse emissions and removals in the latter part of this century. Mexico indicated in its Intended Nationally Determined Contribution and its Climate Change Mid-Century Strategy that the land sector will contribute to meeting GHG emission reduction goals. Since 2012, the Mexican government through its National Forestry Commission, with international financial and technical support, has been developing carbon dynamics models to explore climate change mitigation options in the forest sector. Following a systems approach, here we assess the biophysical mitigation potential of forest ecosystems, harvested wood products and their substitution benefits (i.e. the change in emissions resulting from substitution of wood for more emissions-intensive products and fossil fuels), for policy alternatives considered by the Mexican government, such as a net zero deforestation rate and sustainable forest management. We used available analytical frameworks (Carbon Budget Model of the Canadian Forest Sector and a harvested wood products model), parameterized with local input data in two contrasting Mexican states. Using information from the National Forest Monitoring System (e.g. forest inventories, remote sensing, disturbance data), we demonstrate that activities aimed at reaching a net-zero deforestation rate can yield significant CO2e mitigation benefits by 2030 and 2050 relative to a baseline scenario (‘business as usual’), but if combined with increasing forest harvest to produce long-lived products and substitute more energy-intensive materials, emissions reductions could also provide other co-benefits (e.g. jobs, illegal logging reduction). We concluded that the relative impact of mitigation activities is locally dependent, suggesting that mitigation strategies should be designed and implemented at sub-national scales. We were also encouraged about the

  13. Quantifying the Benefit of Early Climate Change Mitigation in Avoiding Biodiversity Loss

    Quantitative simulations of the global-scale benefits of climate change mitigation in avoiding biodiversity loss are presented. Previous studies have projected widespread global and regional impacts of climate change on biodiversity. However, these have focused on analysis of business-as-usual scenarios, with no explicit mitigation policy included. This study finds that early, stringent mitigation would avoid a large proportion of the impacts of climate change induced biodiversity loss projected for the 2080s. Furthermore, despite the large number of studies addressing extinction risks in particular species groups, few studies have explored the issue of potential range loss in common and widespread species. Our study is a comprehensive global scale analysis of 48,786 common and widespread species. We show that without climate change mitigation, 57+/-6% of the plants and 34+/-7% of the animals studied are likely to lose over 50% of their present climatic range by the 2080s. This estimate incorporates realistic, taxon-specific dispersal rates. With stringent mitigation, in which emissions peak in 2016 and are reduced by 5% annually thereafter, these losses are reduced by 60%. Furthermore, with stringent mitigation, global temperature rises more slowly, allowing an additional three decades for biodiversity to adapt to a temperature rise of 2C above pre-industrial levels. The work also shows that even with mitigation not all the impacts can now be avoided, and ecosystems and biodiversity generally has a very limited capacity to adapt. Delay in mitigation substantially reduces the percentage of impacts that can be avoided, for example if emissions do not peak until 2030, the percentage of losses that can be avoided declines to 40%. Since even small declines in common and widespread species can disrupt ecosystem function and services, these results indicate that without mitigation, globally widespread losses in ecosystem service provision are to be expected.

  14. Dietary changes to mitigate climate change and benefit public health in China.

    Dietary change presents an opportunity to meet the dual challenges of non-communicable diseases and the effects of climate change in China. Based on a food survey and reviewed data sets, we linked nutrient composition and carbon footprint data by aggregating 1950 types of foods into 28 groups. Nine dietary scenarios for both men and women were modeled based on the current diet and latest National Program for Food and Nutrition. Linear uncertainty optimization was used to produce diets meeting the Chinese Dietary Reference Intakes for adults aged 18-50years while minimizing carbon footprints. The theoretical optimal diet reduced daily footprints by 46%, but this diet was unrealistic due to limited food diversity. Constrained by acceptability, the optimal diet reduced the daily carbon footprints by 7-28%, from 3495 to 2517-3252g CO 2 e, for men and by 5-26%, from 3075 to 2280-2917g CO 2 e, for women. Dietary changes for adults are capable of benefiting China in terms of the considerable footprint reduction of 53-222Mt.CO 2 eyear -1 , when magnified based on the Chinese population, which is the largest worldwide. Seven of eight scenarios showed that reductions in meat consumption resulted in greater reductions in greenhouse gas emissions. However, dramatic reductions in meat consumption may produce smaller reductions in emissions, as the consumption of other ingredients increases to compensate for the nutrients in meat. A trade-off between poultry and other meats (beef, pork, and lamb) is usually observed, and rice, which is a popular food in China, was the largest contributor to carbon footprint reductions. Our findings suggest that changing diets for climate change mitigation and human health is possible in China, though the per capital mitigation potential is slight lower than that in developed economies of France, Spain, Sweden, and New Zealand.

    To evaluate the mitigation potential provided by the SOC pool, we investigated the impact of woody encroachment in the 0-30 cm depth of mineral soil across a natural succession from abandoned pastures and croplands to broadleaves forests on the central Apennine in Italy. In parallel, to assess the effect of the land use change (LUC) from cropland to pasture, a series of pastures established on former agricultural sites, abandoned at different time in the past, were also investigated. Our results show that woody encroachment on former pastures and croplands contributes largely to mitigate climate change, with an increase of the original SOC stock of 45% (40.5 Mg C ha -1 ) and 120% (66.5 Mg C ha -1 ), respectively. Also the LUC from croplands to pastures, greatly contributes to climate change mitigation trough a SOC increase of about 80% of the original SOC (45.9 Mg C ha -1 ). The management of abandoned lands represent a crucial point in the mitigation potential of agriculture and forestry activities, and particularly the role of the SOC pool. A policy effort should focus on minimizing the risk of speculative management options, particularly when the value of woody biomass become convenient to supply new energy systems allowing monetizing a long term forests productivity. In conclusion, despite both the land abandonment and the LUC can have a different impact on the SOC pool under different climatic conditions, these results can be useful to improve the SOC estimates in the National greenhouse gases Inventory at country level.

  16. Policies and Measures to Realise Industrial Energy Efficiency and Mitigate Climate Change

    The industrial sector is responsible for a significant share of global energy use and carbon dioxide (CO 2 ) emissions. Energy efficiency is commonly seen as the most cost-effective, least-polluting, and most readily-accessible industrial energy saving option available in the industrial sector worldwide. Capturing the full extent of these potential end-use energy efficiency improvements rapidly is essential if the world is to be on a path to stabilise greenhouse gas (GHG) concentrations to a level that would prevent dangerous anthropogenic interference with the climate system. In the International Energy Agency (IEA) 450 parts per million stabilisation scenario, over a quarter of all energy efficiency gains need to come from the industrial sector by 2050, largely by changing the pattern of industrial energy use. The reduction potential estimated by IEA and the Intergovernmental Panel on Climate Change (IPCC) for five energy-intensive industrial sub-sectors ranges from about 10 to 40 per cent, depending upon the sector. There is significant potential to reduce, at low or no cost, the amount of energy used to manufacture most commodities. Many policies and programmes - at a national level - have already demonstrated significant improvements in industrial energy efficiency. The associate reduction in energy needs often also improves economic competitiveness as well as mitigates GHG emissions. However, at an international level, approaches such as the Clean Development Mechanism (CDM) are not yet delivering the expected energy efficiency improvements. Existing and effective industrial energy efficiency policies and measures could be replicated at a global level. Key elements of those policies and measures include increasing facility management attention to the issue of energy efficiency; promoting the dissemination of information, practice, and tools; increasing the auditing and implementation capacity; and developing the market for industrial energy efficiency

    The Working Group III contribution to the IPCC Fourth Assessment Report (AR4) focuses on new literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change, published since the IPCC Third Assessment Report (TAR) and the Special Reports on CO{sub 2} Capture and Storage (SRCCS) and on Safeguarding the Ozone Layer and the Global Climate System (SROC).The main aim of this summary report is to assess options for mitigating climate change. Several aspects link climate change with development issues. This report explores these links in detail, and illustrates where climate change and sustainable development are mutually reinforcing. Economic development needs, resource endowments and mitigative and adaptive capacities differ across regions. There is no one-size-fits-all approach to the climate change problem, and solutions need to be regionally differentiated to reflect different socio-economic conditions and, to a lesser extent, geographical differences. Although this report has a global focus, an attempt is made to differentiate the assessment of scientific and technical findings for the various regions.

  20. How reliably can climate change and mitigation policy impacts on electric utilities be assessed?

    Dowlatabadi, H.; Kopp, R.J.; Palmer, K.; De Witt, D.

    1993-01-01

    Numerous mechanisms link climate change and electric utilities. Electricity generation releases radiatively active trace substances (RATS). Significant changes in atmospheric concentration of RATS can lead to a change in regional and global climate regimes. Mitigation action designed to prevent or limit climate change is possible through curbing emissions. Climate change and related mitigation actions impact on electric utilities. Foresight in electric utility planning requires reliable predictions of how the utilities may be affected in the decades ahead. In this paper the impacts of climate change and mitigation policies are noted, and our ability to assess these is reviewed. To this end a suite of models exploring supply and demand questions have been developed. The overall conclusion of the study is that the demand-side uncertainties dominate other unknowns and need to be better characterized and understood. (author)

  1. Chinese Tourists’ Perceptions of Climate Change and Mitigation Behavior: An Application of Norm Activation Theory

    Guiqiang Qiao

    2017-07-01

    Full Text Available It is well recognized that tourism development is a prominent contributor to climate change, but is also a “victim” of climate change. Therefore, to mitigate climate change is of great importance for the sustainability of tourism. Yet extant studies regarding tourism and climate change tend to be dominated by a supply-side stance, albeit the core role of the tourist in the tourism industry. While researchers are increasingly adopting a tourist perspective, few seek to understand the linkage between climate change and tourists’ specific mitigation behaviors in a tourism context; this is especially so in China. This study investigates the impact of Chinese tourists’ perceptions of climate change on their mitigation behaviors based on norm activation theory. Drawing on 557 self-administrated questionnaires collected in China, it finds that tourists’ perceptions of climate change and perceived contribution of tourism to climate change both positively affect energy saving and carbon reduction behavior in tourism. Yet, compared with perceived contribution of tourism to climate change, tourists’ perceptions of climate change are found to be a much stronger predictor for energy saving and carbon reduction behavior. Therefore, it suggests that tourists’ perceptions of climate change in a general context is more strongly related to climate change mitigation behavior in tourism, calling for attention to go beyond the tourism context to alleviate the negative impacts of tourism on climate change.

  3. Distributional impacts of climate change mitigation in Indian electricity: The influence of governance

    Rao, Narasimha D.

    2013-01-01

    Studies that examine the distributional impacts of climate change mitigation policies often neglect the influence of institutions that implement these policies. This study examines the short-term consumption-side distributional impacts of expanding low-carbon electric supply in the state of Maharashtra, India with a focus on the influence of regulatory discretion in pricing. Households' welfare impacts from economy-wide electricity price shocks are simulated against a baseline that is calibrated to actual household economic and electricity service conditions, including actual electricity budgets, block tier prices and supply rationing. Industrial price impacts are propagated to households using a Leontief input–output analysis. Regulatory pricing decisions are evaluated based on social welfare metrics for economic efficiency and income inequality. The analysis reveals new linkages between climate change mitigation, electricity policy and income distribution. Low-income households can be shielded from mitigation impacts without losses in aggregate welfare to the extent that regulators can recover mitigation costs through industrial price increases. Regulators' flexibility to distribute costs across households is constrained by industrial customers' migration off the grid. Reduced supply interruptions to the rural poor from the resulting demand contraction are a potential co-benefit of mitigation. Distributional impacts, therefore, depend on other electricity policies that are driven by the political economy of the sector. - Highlights: • Indirect price increases harm most households less than residential price increases. • Regulators have flexibility to distribute mitigation costs across income groups. • Reduced supply interruptions are a potential co-benefit of mitigation

  5. Public private partnerships for climate change mitigation – An Indian case

    Tharun Dolla

    2017-01-01

    Full Text Available Cities are one of the major contributors to greenhouse gas emissions. Climate change poses serious threat to urban infrastructure, quality of life, and entire urban systems. Cities need to adopt an integrated approach for improvement of city services in order to adapt to climate change and reduce their greenhouse emissions. However, the magnitude of investment required to bridge the widening infrastructure service provision demand-supply gap along with the additional investment to mitigate climate change demands the need to look for innovative financing solutions. Private investments through public private partnership (PPP route offer an innovative mechanism for meet both the goals of infrastructure development and climate change mitigation. Private parties in PPP, however, focuses on the project economics only though they have the potential to provide innovative technical, financial and managerial solutions. The paper aims to answer the question how to integrate climate change mitigation objective in procurement process of PPP projects. The study has focused only on PPP projects in Municipal Solid Waste Management sector. The integration of climate change mitigation objective has been through design of a modified procurement protocol which promote private sector to devise project structure that fulfil both the objectives of climate change mitigation and provision of quality infrastructure services.

  6. The Role of Health Co-Benefits in the Development of Australian Climate Change Mitigation Policies

    Workman, Annabelle; Blashki, Grant; Karoly, David; Wiseman, John

    2016-01-01

    Reducing domestic carbon dioxide and other associated emissions can lead to short-term, localized health benefits. Quantifying and incorporating these health co-benefits into the development of national climate change mitigation policies may facilitate the adoption of stronger policies. There is, however, a dearth of research exploring the role of health co-benefits on the development of such policies. To address this knowledge gap, research was conducted in Australia involving the analysis of several data sources, including interviews carried out with Australian federal government employees directly involved in the development of mitigation policies. The resulting case study determined that, in Australia, health co-benefits play a minimal role in the development of climate change mitigation policies. Several factors influence the extent to which health co-benefits inform the development of mitigation policies. Understanding these factors may help to increase the political utility of future health co-benefits studies. PMID:27657098

To address this knowledge gap, research was conducted in Australia involving the analysis of several data sources, including interviews carried out with Australian federal government employees directly involved in the development of mitigation policies. The resulting case study determined that, in Australia, health co-benefits play a minimal role in the development of climate change mitigation policies. Several factors influence the extent to which health co-benefits inform the development of mitigation policies. Understanding these factors may help to increase the political utility of future health co-benefits studies.

    Agriculture is one of the main contributors to greenhouse gas (GHG) emissions in Bangladesh and rice production is one of the largest sources of GHG emissions. This study considers measurements from two test sites, situated in Mymensingh (Bangladesh), to calibrate and validate the biogeochemical model DailyDayCent and estimate the mitigation potential of alternative management practices at the sites. There are two different N application treatments on the two test sites, which are on the first site a control with no N application and a mineral fertilizer application (120 kg N ha-1) and on the second site only a mineral fertilizer application (110 kg N ha-1). For mitigation, the water management is modified in a modelling approach to estimate the mitigation potential for reducing GHG emissions. The model shows partial agreement with the observations. The modifications to the water management, by changing from permanent wetting to alternate wetting, shows a decrease in GHG emissions of up to 46 % and 37 % for the two test sites, respectively. These tests enable an optimization of the management options to reduce the GHG emissions while maintaining yields.

  9. Addressing Climate Change Mitigation and Adaptation Together: A Global Assessment of Agriculture and Forestry Projects

    Kongsager, Rico; Locatelli, Bruno; Chazarin, Florie

    2016-02-01

    Adaptation and mitigation share the ultimate purpose of reducing climate change impacts. However, they tend to be considered separately in projects and policies because of their different objectives and scales. Agriculture and forestry are related to both adaptation and mitigation: they contribute to greenhouse gas emissions and removals, are vulnerable to climate variations, and form part of adaptive strategies for rural livelihoods. We assessed how climate change project design documents (PDDs) considered a joint contribution to adaptation and mitigation in forestry and agriculture in the tropics, by analyzing 201 PDDs from adaptation funds, mitigation instruments, and project standards [e.g., climate community and biodiversity (CCB)]. We analyzed whether PDDs established for one goal reported an explicit contribution to the other (i.e., whether mitigation PDDs contributed to adaptation and vice versa). We also examined whether the proposed activities or expected outcomes allowed for potential contributions to the two goals. Despite the separation between the two goals in international and national institutions, 37 % of the PDDs explicitly mentioned a contribution to the other objective, although only half of those substantiated it. In addition, most adaptation (90 %) and all mitigation PDDs could potentially report a contribution to at least partially to the other goal. Some adaptation project developers were interested in mitigation for the prospect of carbon funding, whereas mitigation project developers integrated adaptation to achieve greater long-term sustainability or to attain CCB certification. International and national institutions can provide incentives for projects to harness synergies and avoid trade-offs between adaptation and mitigation.

  15. Global assessment of technological innovation for climate change adaptation and mitigation in developing world.

    Adenle, Ademola A; Azadi, Hossein; Arbiol, Joseph

    2015-09-15

    Concerns about mitigating and adapting to climate change resulted in renewing the incentive for agricultural research investments and developing further innovation priorities around the world particularly in developing countries. In the near future, development of new agricultural measures and proper diffusion of technologies will greatly influence the ability of farmers in adaptation and mitigation to climate change. Using bibliometric approaches through output of academic journal publications and patent-based data, we assess the impact of research and development (R&D) for new and existing technologies within the context of climate change mitigation and adaptation. We show that many developing countries invest limited resources for R&D in relevant technologies that have great potential for mitigation and adaption in agricultural production. We also discuss constraints including weak infrastructure, limited research capacity, lack of credit facilities and technology transfer that may hinder the application of innovation in tackling the challenges of climate change. A range of policy measures is also suggested to overcome identified constraints and to ensure that potentials of innovation for climate change mitigation and adaptation are realized.

  16. Climate change mitigation and adaptation in strategic environmental assessment

    Wende, Wolfgang; Bond, Alan; Bobylev, Nikolai; Stratmann, Lars

    2012-01-01

    Countries are implementing CO 2 emission reduction targets in order to meet a globally agreed global warming limit of +2 °C. However, it was hypothesised that these national reduction targets are not translated to regional or state level planning, and are not considered through Strategic Environmental Assessment (SEA) in order to meet emission reduction obligations falling on the transport, energy, housing, agriculture, and forestry sectors. SEAs of land use plans in the German state of Saxony, and the English region of the East of England were examined for their consideration of climate change impacts based on a set of criteria drawn from the literature. It was found that SEAs in both cases failed to consider climate change impacts at scales larger than the boundary of the spatial plan, and that CO 2 reduction targets were not considered. This suggests a need for more clarity in the legal obligations for climate change consideration within the text of the SEA Directive, a requirement for monitoring of carbon emissions, a need for methodological guidance to devolve global climate change targets down to regional and local levels, and a need for guidance on properly implementing climate change protection in SEA. - Highlights: ► Strategic Environmental Assessments (SEA) of 12 land use plans from Germany and England have been examined. ► SEA failed to consider climate change impacts at scales larger than the boundary of the land use plans. ► SEA should be an important instrument for climate protection. ► Concrete steps for climate protection mainstreaming into SEA at the European Union and national levels have been suggested.

  18. Biodiversity as a solution to mitigate climate change impacts on the functioning of forest ecosystems.

    Hisano, Masumi; Searle, Eric B; Chen, Han Y H

    2018-02-01

    Forest ecosystems are critical to mitigating greenhouse gas emissions through carbon sequestration. However, climate change has affected forest ecosystem functioning in both negative and positive ways, and has led to shifts in species/functional diversity and losses in plant species diversity which may impair the positive effects of diversity on ecosystem functioning. Biodiversity may mitigate climate change impacts on (I) biodiversity itself, as more-diverse systems could be more resilient to climate change impacts, and (II) ecosystem functioning through the positive relationship between diversity and ecosystem functioning. By surveying the literature, we examined how climate change has affected forest ecosystem functioning and plant diversity. Based on the biodiversity effects on ecosystem functioning (B→EF), we specifically address the potential for biodiversity to mitigate climate change impacts on forest ecosystem functioning. For this purpose, we formulate a concept whereby biodiversity may reduce the negative impacts or enhance the positive impacts of climate change on ecosystem functioning. Further B→EF studies on climate change in natural forests are encouraged to elucidate how biodiversity might influence ecosystem functioning. This may be achieved through the detailed scrutiny of large spatial/long temporal scale data sets, such as long-term forest inventories. Forest management strategies based on B→EF have strong potential for augmenting the effectiveness of the roles of forests in the mitigation of climate change impacts on ecosystem functioning. © 2017 Cambridge Philosophical Society.

    2012-06-01

    Full Text Available Climate change is one of today's most pressing global issues. Policies to guide mitigation and adaptation are needed to avoid the devastating impacts of climate change. The health sector is a significant contributor to greenhouse gas emissions in developed countries, and its climate impact in low-income countries is growing steadily. This paper reviews and discusses the literature regarding health sector mitigation potential, known and hypothetical co-benefits, and the potential of health information technology, such as eHealth, in climate change mitigation and adaptation. The promising role of eHealth as an adaptation strategy to reduce societal vulnerability to climate change, and the link's between mitigation and adaptation, are also discussed. The topic of environmental eHealth has gained little attention to date, despite its potential to contribute to more sustainable and green health care. A growing number of local and global initiatives on ‘green information and communication technology (ICT’ are now mentioning eHealth as a promising technology with the potential to reduce emission rates from ICT use. However, the embracing of eHealth is slow because of limitations in technological infrastructure, capacity and political will. Further research on potential emissions reductions and co-benefits with green ICT, in terms of health outcomes and economic effectiveness, would be valuable to guide development and implementation of eHealth in health sector mitigation and adaptation policies.

  3. Bioenergy expansion in the EU: Cost-effective climate change mitigation, employment creation and reduced dependency on imported fuels

    Berndes, Goeran; Hansson, Julia

    2007-01-01

    Presently, the European Union (EU) is promoting bioenergy. The aim of this paper is to study the prospects for using domestic biomass resources in Europe and specifically to investigate whether different policy objectives underlying the promotion of bioenergy (cost-effective climate change mitigation, employment creation and reduced dependency on imported fuels) agree on which bioenergy options that should be used. We model bioenergy use from a cost-effectiveness perspective with a linear regionalized energy- and transport-system model and perform supplementary analysis. It is found that the different policy objectives do not agree on the order of priority among bioenergy options. Maximizing climate benefits cost-effectively is in conflict with maximizing employment creation. The former perspective proposes the use of lignocellulosic biomass in the stationary sector, while the latter requires biofuels for transport based on traditional agricultural crops. Further, from a security-of-supply perspective, the appeal of a given bioenergy option depends on how oil and gas import dependencies are weighed relative to each other. Consequently, there are tradeoffs that need to be addressed by policymakers promoting the use of bioenergy. Also, the importance of bioenergy in relation to employment creation and fuel import dependency reduction needs to be further addressed

    Full Text Available There is growing concern about climate change impacts on local government areas. In Australia, the federal carbon tax (from 1 July 2012 will also increase costs for local councils. This paper evaluates what carbon mitigation (i.e. energy, water, and waste management actions have been implemented by metropolitan Adelaide councils (n=14 and why (or why not. A survey of environmental officers profiled carbon mitigation actions, emissions auditing, and motives for emissions reduction by Adelaide councils. The main reasons for adopting carbon actions were a climate change plan, climate leadership, and cost savings. Internal council governance of climate change actions was also evaluated. A climate governance framework based on adaptive management, communication, and reflective practice (Nursey-Bray 2010 was applied to assess climate mitigation by Adelaide councils.

  8. Terraforming the Planets and Climate Change Mitigation on Earth

    Toon, O. B.

    2008-12-01

    Hopefully, purposeful geo-engineering of the Earth will remain a theoretical concept. Of course, we have already inadvertently changed the Earth, and over geologic history life has left an indelible imprint on our planet. We can learn about geo-engineering schemes by reference to Earth history, for example climate changes after volcanic eruptions provide important clues to using sulfates to modify the climate. The terrestrial planets and Titan offer additional insights. For instance, Mars and Venus both have carbon dioxide dominated greenhouses. Both have more than 10 times as much carbon dioxide in their atmospheres as Earth, and both absorb less sunlight than Earth, yet one is much colder than Earth and one is much hotter. These facts provide important insights into carbon dioxide greenhouses that I will review. Mars cools dramatically following planet wide dust storms, and Titan has what is referred to as an anti- greenhouse climate driven by aerosols. These data can be used to reassure us that we can model aerosol caused changes to the climate of a planet, and also provide examples of aerosols offsetting a gas-driven greenhouse effect. People have long considered whether we might make the other planets habitable. While most of the schemes considered belong in the realm of science fiction, it is possible that some schemes might be practical. Terraforming brings to mind a number of issues that are thought provoking, but not so politically charged as geo-engineering. For example: What criteria define habitability, is it enough for people to live in isolated glass enclosures, or do we need to walk freely on the planet? Different creatures have different needs. Is a planet habitable if plants can thrive in the open, or do animals also need to be free? Are the raw materials present on any planet to make it habitable? If not, can we make the materials, or do we have to import them? Is it ethical to change a planetary climate? What if there are already primitive

  9. Technological change and the timing of mitigation measures

    Gruebler, A.; Messner, S.

    1998-01-01

    We use a coupled carbon-cycle and energy systems engineering model to analyze the future time path of carbon emissions under an illustrative CO 2 concentration stabilization limit of 550 ppm. Our findings confirm the emission pattern as found by WRE: global emissions rise initially, pass through stabilization, in order to decline in the second half of the 21st century. We show that for a given CO 2 concentration target, emission trajectories within an intertemporal optimization framework depend mainly on two factors: the discount rate, and the representation of technological change as either static or dynamic. We obtain a similar near-term emission time path as WRE when using a model with static technology and a discount rate of 7%. We obtain a trajectory with lower emissions in the near-term when using a lower discount rate and/or treating technology dynamics endogenously in the model. We briefly outline a model that endogenizes technological change through learning curves. We then compare differences in emission trajectories between alternative model formulations of technological change. They are sufficiently small as to be of secondary importance when compared to treating CO 2 concentration stabilization as an inter-temporal optimization problem or not. Whereas our results confirm the computational results of WRE, we arrive nonetheless at different policy conclusions. If long-term emission reduction is the goal, we cannot follow 'business as usual' even in the short-term. Action needs to start now. Action does not necessarily mean aggressive short-term emission reductions but rather enhanced R and D and technology demonstration efforts that stimulate technological learning. These are the necessary preconditions that long-term reduction targets can be met with improved technology and at costs lower than today. We close by pointing out two further critical issues: uncertainty, and the possible mismatch between the world of economic models and that of climate

  10. Using Local Stories as a Call to Action on Climate Change Adaptation and Mitigation in Minnesota

    Phipps, M.

    2015-12-01

    Climate Generation: A Will Steger Legacy and the University of Minnesota's Regional Sustainability Development Partnerships (RSDP) have developed a novel approach to engaging rural Minnesotans on climate change issues. Through the use of personal, local stories about individuals' paths to action to mitigate and or adapt to climate change, Climate Generation and RSDP aim to spur others to action. Minnesota's Changing Climate project includes 12 Climate Convenings throughout rural Minnesota in a range of communities (tourism-based, agrarian, natural resources-based, university towns) to engage local populations in highly local conversations about climate change, its local impacts, and local solutions currently occurring. Climate Generation and RSDP have partnered with Molly Phipps Consulting to evaluate the efficacy of this approach in rural Minnesota. Data include pre and post convening surveys examining participants' current action around climate change, attitudes toward climate change (using questions from Maibach, Roser-Renouf, and Leiserowitz, 2009), and the strength of their social network to support their current and ongoing work toward mitigating and adapting to climate change. Although the Climate Convenings are tailored to each community, all include a resource fair of local organizations already engaging in climate change mitigation and adaptation activities which participants can participate in, a welcome from a trusted local official, a presentation on the science of climate change, sharing of local climate stories, and break-out groups where participants can learn how to get involved in a particular mitigation or adaptation strategy. Preliminary results have been positive: participants feel motivated to work toward mitigating and adapting to climate change, and more local stories have emerged that can be shared in follow-up webinars and on a project website to continue to inspire others to act.

  11. Renewable Energy Production from Waste to Mitigate Climate Change and Counteract Soil Degradation - A Spatial Explicit Assessment for Japan

    Kraxner, Florian; Yoshikawa, Kunio; Leduc, Sylvain; Fuss, Sabine; Aoki, Kentaro; Yamagata, Yoshiki

    2014-05-01

    Waste production from urban areas is growing faster than urbanization itself, while at the same time urban areas are increasingly contributing substantial emissions causing climate change. Estimates indicate for urban residents a per capita solid waste (MSW) production of 1.2 kg per day, subject to further increase to 1.5 kg beyond 2025. Waste water and sewage production is estimated at about 260 liters per capita and day, also at increasing rates. Based on these figures, waste - including e.g. MSW, sewage and animal manure - can generally be assumed as a renewable resource with varying organic components and quantity. This paper demonstrates how new and innovative technologies in the field of Waste-to-Green Products can help in various ways not only to reduce costs for waste treatment, reduce the pressure on largely overloaded dump sites, and reduce also the effect of toxic materials at the landfill site and by that i.e. protect the groundwater. Moreover, Waste-to-Green Products can contribute actively to mitigating climate change through fossil fuel substitution and carbon sequestration while at the same time counteracting negative land use effects from other types of renewable energy and feedstock production through substitution. At the same time, the co-production and recycling of fertilizing elements and biochar can substantially counteract soil degradation and improve the soil organic carbon content of different land use types. The overall objective of this paper is to assess the total climate change mitigation potential of MSW, sewage and animal manure for Japan. A techno-economic approach is used to inform the policy discussion on the suitability of this substantial and sustainable mitigation option. We examine the spatial explicit technical mitigation potential from e.g. energy substitution and carbon sequestration through biochar in rural and urban Japan. For this exercise, processed information on respective Japanese waste production, energy demand

  12. Nuclear Energy's Role in Mitigating Climate Change and Air Pollution

    2013-01-01

    Energy experts expect energy demand to rise dramatically in the 21st century, especially in developing countries, where today, over one billion people have no access to modern energy services. Meeting global energy demand will require a 75% expansion in primary energy supply by 2050. If no steps are taken to reduce emissions, the energy-related CO 2 emissions would nearly double in the same period. The increased levels of this greenhouse gas in the atmosphere could raise average global temperatures 3 o C or more above pre-industrial levels, which may trigger the dangerous anthropogenic interference with the climate system, which the United Nations Framework Convention on Climate Change seeks to prevent.

  13. Assessment of Clmate Change Mitigation Strategies for the Road Transport Sector of India

    Singh, N.; Mishra, T.; Banerjee, R.

    2017-12-01

    India is one of the fastest growing major economies of the world. It imports three quarters of its oil demand, making transport sector major contributor of greenhouse gas (GHG) emissions. 40% of oil consumption in India comes from transport sector and over 90% of energy demand is from road transport sector. This has led to serious increase in CO2 emission and concentration of air pollutants in India. According to Intergovernmental Panel on Climate Change (IPCC), transport can play a crucial role for mitigation of global greenhouse gas emissions. Therefore, assessment of appropriate mitigation policies is required for emission reduction and cost benefit potential. The present study aims to estimate CO2, SO2, PM and NOx emissions from the road transport sector for the base year (2014) and target year (2030) by applying bottom up emission inventory model. Effectiveness of different mitigation strategies like inclusion of natural gas as alternate fuel, penetration of electric vehicle as alternate vehicle, improvement of fuel efficiency and increase share of public transport is evaluated for the target year. Emission reduction achieved from each mitigation strategies in the target year (2030) is compared with the business as usual scenario for the same year. To obtain cost benefit analysis, marginal abatement cost for each mitigation strategy is estimated. The study evaluates mitigation strategies not only on the basis of emission reduction potential but also on their cost saving potential.

  15. Using wood products to mitigate climate change: External costs and structural change

    Sathre, Roger; Gustavsson, Leif [Ecotechnology, Mid Sweden University, 831 25 Oestersund (Sweden)

    2009-02-15

    In this study we examine the use of wood products as a means to mitigate climate change. We describe the life cycle of wood products including forest growth, wood harvest and processing, and product use and disposal, focusing on the multiple roles of wood as both material and fuel. We present a comparative case study of a building constructed with either a wood or a reinforced concrete frame. We find that the production of wood building material uses less energy and emits less carbon than the production of reinforced concrete material. We compare the relative cost of the two building methods without environmental taxation, under the current Swedish industrial energy taxation regime, and in scenarios that incorporate estimates of the full social cost of carbon emission. We find that the inclusion of climate-related external costs improves the economic standing of wood construction vis-a-vis concrete construction. We conclude that policy instruments that internalise the external costs of carbon emission should encourage a structural change toward the increased use of sustainably produced wood products.

  16. Update of indicators for climate change mitigation in Greece

    Dimitroulopoulou, C.; Ziomas, I.

    2011-01-01

    This paper analyses the factors affecting greenhouse gas (GHG) emissions in Greece, (i.e. the drivers of pressures on climate change), using environmental indicators related to energy, demographics and economic growth. The analysis is based on the data of 2008 and considers types of fuel and sectors. The Kaya identity is used to identify the relationship between drivers and pressures, using annual time series data of National GHG emissions, population, energy consumption and gross domestic product. The analysis shows that over the period 2000-2008, GHG emissions show a slight variation, but they are almost stabilised, with a total increase of 1.6%. Despite the economic growth over that period, this stabilisation may be considered as a combination of reductions in the energy intensity of GDP and the carbon intensity of energy, which are affected by improvements in energy efficiency and introduction of 'cleaner' fuels, such as natural gas and renewables in the energy mixture of the country. - Highlights: → We analyse drivers affecting GHG emissions (pressures on climate) in Greece, using indicators. → Indicators relate to energy, demographics and economic growth. → Kaya identity identifies the relationship between drivers and pressures. → GHG emissions are almost stable due to reductions in energy intensity and carbon intensity of energy. → Improvements in energy efficiency and introduction of clean fuels in energy mix reduce emissions.

  17. Modelling effects of geoengineering options in response to climate change and global warming: implications for coral reefs.

    Crabbe, M J C

    2009-12-01

    Climate change will have serious effects on the planet and on its ecosystems. Currently, mitigation efforts are proving ineffectual in reducing anthropogenic CO2 emissions. Coral reefs are the most sensitive ecosystems on the planet to climate change, and here we review modelling a number of geoengineering options, and their potential influence on coral reefs. There are two categories of geoengineering, shortwave solar radiation management and longwave carbon dioxide removal. The first set of techniques only reduce some, but not all, effects of climate change, while possibly creating other problems. They also do not affect CO2 levels and therefore fail to address the wider effects of rising CO2, including ocean acidification, important for coral reefs. Solar radiation is important to coral growth and survival, and solar radiation management is not in general appropriate for this ecosystem. Longwave carbon dioxide removal techniques address the root cause of climate change, rising CO2 concentrations, they have relatively low uncertainties and risks. They are worthy of further research and potential implementation, particularly carbon capture and storage, biochar, and afforestation methods, alongside increased mitigation of atmospheric CO2 concentrations.

    1998-01-01

    It is widely accepted that human activities which produce greenhouse gases have had a discernible effect upon global mean temperatures over the last 50 years. A number of gases entering the atmosphere as a result of human activities can act as greenhouse gases. The most important is carbon dioxide the atmospheric concentration of which has risen by about 30% compared to pre-industrial concentrations. Energy related emissions arising from the use of fossil fuels account for more than 80% of the CO 2 released to the atmosphere each year with these fuels accounting for around 90% of the world's commercial energy production. The provisions of the 1997 Kyoto protocol go some way to promote reductions in emissions of greenhouse gases and are an important first step. However, according to this presentation, current energy production and consumption patterns violate principles of sustainability. As a result the world is committed to warming as a result of emissions of greenhouse gases from the use of these fuels. Pragmatically, one should limit the use of fossil fuels and eventually replace them by renewable energy sources.and efforts to increase the overall energy efficiency. Given this, proposals to sequester and dump/store carbon dioxide are an unsustainable solution in their own right, but also perpetuate unsustainable energy use based on fossil fuels. Probably attempts to limit the impacts of climate change by the capture and disposal of CO 2 will result in undesirable and unanticipated impacts. The presentation recommends that resources currently deployed in investigating disposal schemes for CO 2 should rather go to the development of renewable energy generation and energy efficiency

    A reduction of energy service demand is a climate mitigation option, but its effectiveness has never been quantified. We quantify the effectiveness of energy service demand reduction in the building, transport, and industry sectors using the Asia-Pacific Integrated Assessment/Computable General Equilibrium (AIM/CGE) model for the period 2015–2050 under various scenarios. There were two major findings. First, a 25% energy service demand reduction in the building, transport, and basic material industry sectors would reduce the GDP loss induced by climate mitigation from 4.0% to 3.0% and from 1.2% to 0.7% in 2050 under the 450 ppm and 550 ppm CO 2 equivalent concentration stabilization scenarios, respectively. Second, the effectiveness of a reduction in the building sector's energy service demand would be higher than those of the other sectors at the same rate of the energy service demand reduction. Furthermore, we also conducted a sensitivity analysis of different socioeconomic conditions, and the climate mitigation target was found to be a key determinant of the effectiveness of energy service demand reduction measures. Therefore, more certain climate mitigation targets would be useful for the decision makers who design energy service demand reduction measures. - Highlights: • The effectiveness of a reduction in energy service demand is quantified. • A 25% reduction in energy service demand would be equivalent to 1% of GDP in 2050. • Stringent mitigation increases the effectiveness of energy service demand reduction. • Effectiveness of a reduction in energy demand service is higher in the building sector

  20. A review of renewable energy sources, sustainability issues and climate change mitigation

    Full Text Available The world is fast becoming a global village due to the increasing daily requirement of energy by all population across the world while the earth in its form cannot change. The need for energy and its related services to satisfy human social and economic development, welfare and health is increasing. Returning to renewables to help mitigate climate change is an excellent approach which needs to be sustainable in order to meet energy demand of future generations. The study reviewed the opportunities associated with renewable energy sources which includes: Energy Security, Energy Access, Social and Economic development, Climate Change Mitigation, and reduction of environmental and health impacts. Despite these opportunities, there are challenges that hinder the sustainability of renewable energy sources towards climate change mitigation. These challenges include Market failures, lack of information, access to raw materials for future renewable resource deployment, and our daily carbon footprint. The study suggested some measures and policy recommendations which when considered would help achieve the goal of renewable energy thus to reduce emissions, mitigate climate change and provide a clean environment as well as clean energy for all and future generations.

  1. Urban Heat Islands and Their Mitigation vs. Local Impacts of Climate Change

    Taha, H.

    2007-12-01

    Urban heat islands and their mitigation take on added significance, both negative and positive, when viewed from a climate-change perspective. In negative terms, urban heat islands can act as local exacerbating factors, or magnifying lenses, to the effects of regional and large-scale climate perturbations and change. They can locally impact meteorology, energy/electricity generation and use, thermal environment (comfort and heat waves), emissions of air pollutants, photochemistry, and air quality. In positive terms, on the other hand, mitigation of urban heat islands (via urban surface modifications and control of man-made heat, for example) can potentially have a beneficial effect of mitigating the local negative impacts of climate change. In addition, mitigation of urban heat islands can, in itself, contribute to preventing regional and global climate change, even if modestly, by helping reduce CO2 emissions from power plants and other sources as a result of decreased energy use for cooling (both direct and indirect) and reducing the rates of meteorology-dependent emissions of air pollutants. This presentation will highlight aspects and characteristics of heat islands, their mitigation, their modeling and quantification techniques, and recent advances in meso-urban modeling of California (funded by the California Energy Commission). In particular, the presentation will focus on results from quantitative, modeling-based analyses of the potential benefits of heat island mitigation in 1) reducing point- and area-source emissions of CO2, NOx, and VOC as a result of reduced cooling energy demand and ambient/surface temperatures, 2) reducing evaporative and fugitive hydrocarbon emissions as a result of lowered temperatures, 3) reducing biogenic hydrocarbon emissions from existing vegetative cover, 4) slowing the rates of tropospheric/ground-level ozone formation and/or accumulation in the urban boundary layer, and 5) helping improve air quality.

  2. Under What Circumstances Do Wood Products from Native Forests Benefit Climate Change Mitigation?

    Heather Keith

    Full Text Available Climate change mitigation benefits from the land sector are not being fully realised because of uncertainty and controversy about the role of native forest management. The dominant policy view, as stated in the IPCC's Fifth Assessment Report, is that sustainable forest harvesting yielding wood products, generates the largest mitigation benefit. We demonstrate that changing native forest management from commercial harvesting to conservation can make an important contribution to mitigation. Conservation of native forests results in an immediate and substantial reduction in net emissions relative to a reference case of commercial harvesting. We calibrated models to simulate scenarios of native forest management for two Australian case studies: mixed-eucalypt in New South Wales and Mountain Ash in Victoria. Carbon stocks in the harvested forest included forest biomass, wood and paper products, waste in landfill, and bioenergy that substituted for fossil fuel energy. The conservation forest included forest biomass, and subtracted stocks for the foregone products that were substituted by non-wood products or plantation products. Total carbon stocks were lower in harvested forest than in conservation forest in both case studies over the 100-year simulation period. We tested a range of potential parameter values reported in the literature: none could increase the combined carbon stock in products, slash, landfill and substitution sufficiently to exceed the increase in carbon stock due to changing management of native forest to conservation. The key parameters determining carbon stock change under different forest management scenarios are those affecting accumulation of carbon in forest biomass, rather than parameters affecting transfers among wood products. This analysis helps prioritise mitigation activities to focus on maximising forest biomass. International forest-related policies, including negotiations under the UNFCCC, have failed to recognize

  5. The role of energy-service demand reduction in global climate change mitigation: Combining energy modelling and decomposition analysis

    Kesicki, Fabian; Anandarajah, Gabrial

    2011-01-01

    In order to reduce energy-related CO 2 emissions different options have been considered: energy efficiency improvements, structural changes to low carbon or zero carbon fuel/technologies, carbon sequestration, and reduction in energy-service demands (useful energy). While efficiency and technology options have been extensively studied within the context of climate change mitigation, this paper addresses the possible role of price-related energy-service demand reduction. For this analysis, the elastic demand version of the TIAM-UCL global energy system model is used in combination with decomposition analysis. The results of the CO 2 emission decomposition indicate that a reduction in energy-service demand can play a limited role, contributing around 5% to global emission reduction in the 21st century. A look at the sectoral level reveals that the demand reduction can play a greater role in selected sectors like transport contributing around 16% at a global level. The societal welfare loss is found to be high when the price elasticity of demand is low. - Highlights: → A reduction in global energy-service demand can contribute around 5% to global emission reduction in the 21st century. → The role of demand is a lot higher in transport than in the residential sector. → Contribution of demand reduction is higher in early periods of the 21st century. → Societal welfare loss is found to be high when the price elasticity of demand is low. → Regional shares in residual emissions vary under different elasticity scenarios.

    This paper deals with the problem of discrete time option pricing by a fractional subdiffusive Black-Scholes model. The price of the underlying stock follows a time-changed geometric fractional Brownian motion. By a mean self-financing delta-hedging argument, the pricing formula for the European call option in discrete time setting is obtained.

  8. Does Climate Change Mitigation Activity Affect Crude Oil Prices? Evidence from Dynamic Panel Model

    Jude C. Dike

    2014-01-01

    Full Text Available This paper empirically investigates how climate change mitigation affects crude oil prices while using carbon intensity as the indicator for climate change mitigation. The relationship between crude oil prices and carbon intensity is estimated using an Arellano and Bond GMM dynamic panel model. This study undertakes a regional-level analysis because of the geographical similarities among the countries in a region. Regions considered for the study are Africa, Asia and Oceania, Central and South America, the EU, the Middle East, and North America. Results show that there is a positive relationship between crude oil prices and carbon intensity, and a 1% change in carbon intensity is expected to cause about 1.6% change in crude oil prices in the short run and 8.4% change in crude oil prices in the long run while the speed of adjustment is 19%.

  18. Mitigating climate change: Decomposing the relative roles of energy conservation, technological change, and structural shift

    Mishra, Gouri Shankar; Zakerinia, Saleh; Yeh, Sonia; Teter, Jacob; Morrison, Geoff

    2014-01-01

    We decompose the contribution of five drivers of energy use and CO 2 emissions reductions in achieving climate change goals over 2005–2100 for various climate policy scenarios. This study contributes to the decomposition literature in three ways. First, it disaggregates drivers of energy demand into technological progress and demand for energy services, represented in terms of useful energy, allowing us to estimate their contributions independently — an improvement over other economy-wide decomposition studies. Secondly, this approach reduces the ambiguity present in many previous measures of structural change. We delineate structural shifts into two separate measures: changes in fuel mix within a given resource or service pathway; and changes in mix among distinct energy resources or end-use services. Finally, this study applies decomposition methods to energy and emission trajectories from two mutually informing perspectives: (i) primary energy resources — crude oil, natural gas, coal, nuclear, and renewables; and (ii) end-uses of energy services — residential and commercial buildings, industry, and transportation. Our results show that technological improvements and energy conservation are important in meeting climate goals in the first half of the coming century; and that nuclear and renewable energy and CCS technology are crucial in meeting more stringent goals in the second half of the century. We examine the relative roles of the drivers in reducing CO 2 emissions separately for developed and developing regions. Although the majority of energy and emission growth – and by extension the greatest opportunities for mitigation – will occur in developing countries, the decomposition shows that the relative roles of the five drivers are broadly consistent between these two regions. - Highlights: • We decompose the contribution of five drivers of energy use and CO2 emissions reductions in achieving climate change goals • We analyze differences

  20. Ethical implications of co-benefits rationale within climate change mitigation strategy

    Rita Vasconcellos Oliveira

    2016-10-01

    Full Text Available Climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a border and consensual perspective, co-benefits are considered here to be emerging advantages of the implementation of measures regarding the lowering of greenhouse gases.Departing from the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized and discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of co-benefits rationale coming from the mentioned examples. The focus is primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame co-benefits rationale, from a moral viewpoint and in relation to the overall climate change mitigation strategy.In this article, we propose the concepts of well-being and freedom, as portrayed by Capabilities Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits and their rationale too. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to favour the climate change mitigation action. Finally, a scenario is drawn where Capabilities Approach is the moral guideline for co-benefits rationale showing this way its potential in terms of enhancing climate change mitigation strategy.

  1. Assessment of air pollution emissions and evaluation of renewable energy as mitigation option-power generation sector of Pakistan

    Harijan, K.H.; Uqaili, M.A.; Memon, M.

    2005-01-01

    Energy is an engine for growth and is linked with all aspects of development, poverty alleviation, and improvement of quality of life. The production, distribution and use of energy particularly fossil fuels have significant environmental impacts. Pakistan has total power generation capacity of 19.25 GW, with 63.9% thermal, 33.7% hydel and 2.4% nuclear share. The electricity generation increased by 7.5% per annum during the last three decades and future demand has been projected to grow at 7%-11 % per annum. This increasing power demand will depend mainly on power generation from fossil fuels. This paper presents the review of power generation situation and assesses the air pollution emissions from thermal power generation in Pakistan. The paper also investigates the prospects of renewable energy- sources for air pollution mitigation in the country. The study indicates that thermal power generation plants are the major source of air pollution emissions in the country. This air pollution has local, regional and global environmental impacts. The paper concludes that the use of renewables such as hydel, wind, solar and biomass energy for power generation can contribute substantially in air pollution mitigation in the country. (author)

  2. Hand in hand: public endorsement of climate change mitigation and adaptation.

    Full Text Available This research investigated how an individual's endorsements of mitigation and adaptation relate to each other, and how well each of these can be accounted for by relevant social psychological factors. Based on survey data from two European convenience samples (N = 616 / 309 we found that public endorsements of mitigation and adaptation are strongly associated: Someone who is willing to reduce greenhouse gas emissions (mitigation is also willing to prepare for climate change impacts (adaptation. Moreover, people endorsed the two response strategies for similar reasons: People who believe that climate change is real and dangerous, who have positive attitudes about protecting the environment and the climate, and who perceive climate change as a risk, are willing to respond to climate change. Furthermore, distinguishing between (spatially proximal and distant risk perceptions suggested that the idea of portraying climate change as a proximal (i.e., local threat might indeed be effective in promoting personal actions. However, to gain endorsement of broader societal initiatives such as policy support, it seems advisable to turn to the distant risks of climate change. The notion that "localising" climate change might not be the panacea for engaging people in this domain is discussed in regard to previous theory and research.

    Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land-based climate change mitigation efforts is highly uncertain. Here, we address this uncertainty by using two land-based mitigation scenarios from two land-use models (IMAGE and MAgPIE) as input to four dynamic global vegetation models (DGVMs; LPJ-GUESS, ORCHIDEE, JULES, LPJmL). Each of the four combinations of land-use models and mitigation scenarios aimed for a cumulative carbon uptake of ~130 GtC by the end of the century, achieved either via the cultivation of bioenergy crops combined with carbon capture and storage (BECCS) or avoided deforestation and afforestation (ADAFF). Results suggest large uncertainty in simulated future land demand and carbon uptake rates, depending on the assumptions related to land use and land management in the models. Total cumulative carbon uptake in the DGVMs is highly variable across mitigation scenarios, ranging between 19 and 130 GtC by year 2099. Only one out of the 16 combinations of mitigation scenarios and DGVMs achieves an equivalent or higher carbon uptake than achieved in the land-use models. The large differences in carbon uptake between the DGVMs and their discrepancy against the carbon uptake in IMAGE and MAgPIE are mainly due to different model assumptions regarding bioenergy crop yields and due to the simulation of soil carbon response to land-use change. Differences between land-use models and DGVMs regarding forest biomass and the rate of forest regrowth also have an impact, albeit smaller, on the results. Given the low confidence in simulated carbon uptake for a given land-based mitigation scenario, and that negative emissions simulated by the DGVMs are typically lower than assumed in scenarios consistent with the 2°C target, relying on negative emissions to mitigate climate change is a highly uncertain strategy. © 2018 John

  8. Accessing international financing for climate change mitigation - A guidebook for developing countries

    Limaye, D.R.; Zhu, X.

    2012-08-15

    This guidebook has been prepared by the UNEP Risoe Centre (URC) as part of its Technology Needs Assessment (TNA) project. The TNA project assists developing countries to identify national mitigation and adaptation technology priorities and to develop Technology Action Plans (TAPs) for mitigation of greenhouse gas (GHG) emissions and climate change adaptation. This guidebook provides information to help TNA countries better identify and access financial resources for the mitigation activities included in their national TAPs. This guidebook covers both mitigation 'projects' (such as a wind farm or a solar PV generation facility) and 'programmes' (such as a credit line for financing energy efficiency projects in small and medium-sized enterprises (SMEs), or bulk procurement and distribution of compact fluorescent lamps to households). The primary emphasis is on multilateral and bilateral sources of financing but the guidebook also includes an overview of private funding sources and public-private partnerships (PPPs). This guidebook only covers international financing for mitigation actions in developing countries. For example, EU funding for EU member countries and Chinese funding for mitigation in China are not covered in this guidebook. However, the EU funding for mitigation in developing countries and Chinese funding supporting mitigation in other developing countries are included. Special funds established in some developing countries by pooling financing support from developed countries are also covered in this guidebook. Information on the financing sources was compiled in a standard format and reviewed and analysed to categorise the financing sources. For the multilateral and bilateral financing sources, the available information was used to define their major characteristics (such as geographic coverage, technology/sector focus, funding sources, financing objectives, financing mechanisms, and management and governance). In addition, the

  9. Carbon farming in hot, dry coastal areas: an option for climate change mitigation

    Becker, K.; Wulfmeyer, V.; Berger, T.; Gebel, J.; Münch, W.

    2013-07-01

    We present a comprehensive, interdisciplinary project which demonstrates that large-scale plantations of Jatropha curcas - if established in hot, dry coastal areas around the world - could capture 17-25 t of carbon dioxide per hectare per year from the atmosphere (over a 20 yr period). Based on recent farming results it is confirmed that the Jatropha curcas plant is well adapted to harsh environments and is capable of growing alone or in combination with other tree and shrub species with minimal irrigation in hot deserts where rain occurs only sporadically. Our investigations indicate that there is sufficient unused and marginal land for the widespread cultivation of Jatropha curcas to have a significant impact on atmospheric CO2 levels at least for several decades. In a system in which desalinated seawater is used for irrigation and for delivery of mineral nutrients, the sequestration costs were estimated to range from 42-63 EUR per tonne CO2. This result makes carbon farming a technology that is competitive with carbon capture and storage (CCS). In addition, high-resolution simulations using an advanced land-surface-atmosphere model indicate that a 10 000 km2 plantation could produce a reduction in mean surface temperature and an onset or increase in rain and dew fall at a regional level. In such areas, plant growth and CO2 storage could continue until permanent woodland or forest had been established. In other areas, salinization of the soil may limit plant growth to 2-3 decades whereupon irrigation could be ceased and the captured carbon stored as woody biomass.

  11. An assessment of the potentials of nuclear power and carbon capture and storage in the long-term global warming mitigation options based on Asian Modeling Exercise scenarios

    Mori, Shunsuke

    2012-01-01

    This paper presents an evaluation of global warming mitigation options based on scenarios from the Asian Modeling Exercise. Using an extended version of the integrated assessment model MARIA-23 (Multiregional Approach for Resource and Industry Allocation), we analyze nuclear fuel recycling options, carbon capture and storage technologies (CCS), and biomass utilization. To assess the potential implications of decreased social acceptance of nuclear power in the wake of the Fukushima nuclear accident, additional scenarios including a nuclear power expansion limitation, are analyzed. We also evaluate MARIA-23 model simulation estimates of long-term contributions and interrelationships among nuclear power, biomass, and CCS. Finally, potential costs of nuclear limitation under carbon control policies are assessed. The simulation results in this paper suggest the following: (1) under the reference scenario, global GDP losses in climate limitation scenarios range from 1.3% per year to 3.9% per year in 2060, rising to between 3.5% per year and 4.5% per year in 2100; (2) the use of nuclear fuel reprocessing technologies increase rapidly in all carbon control policy scenarios; (3) under a scenario where the price of CO 2 is $30 and nuclear power expansion is strictly limited, GDP losses increase significantly—from 4.5% per year to 6.4% per year by 2100; (4) nuclear power and CCS are substitute mitigation technologies. With nuclear power technology available CCS deployment reaches approximately 15,000 Mt-CO 2 per year by 2010; without a nuclear power option, CCS deployment rises to more than 80,000 Mt-CO 2 per year; and (5) biomass utilization cannot fully compensate for limitations to nuclear power expansion in policy scenarios. In addition to examining the role of these three technologies on global scales, we report results for several major Asian regions, namely Japan, China, and India. China tends to deploy nuclear power (if available) in response to rapidly growing

The taxation of these emissions has encouraged the development of more energy-efficient and environmental-friendly solutions, of which three...

  13. US major crops’ uncertain climate change risks and greenhouse gas mitigation benefits

    Wing, Ian Sue; Monier, Erwan; Stern, Ari; Mundra, Anupriya

    2015-01-01

    We estimate the costs of climate change to US agriculture, and associated potential benefits of abating greenhouse gas emissions. Five major crops’ yield responses to climatic variation are modeled empirically, and the results combined with climate projections for a no-policy, high-warming future, as well as moderate and stringent mitigation scenarios. Unabated warming reduces yields of wheat and soybeans by 2050, and cotton by 2100, but moderate warming increases yields of all crops except wheat. Yield changes are monetized using the results of economic simulations within an integrated climate-economy modeling framework. Uncontrolled warming’s economic effects on major crops are slightly positive—annual benefits <$4 B. These are amplified by emission reductions, but subject to diminishing returns—by 2100 reaching $17 B under moderate mitigation, but only $7 B with stringent mitigation. Costs and benefits are sensitive to irreducible uncertainty about the fertilization effects of elevated atmospheric carbon dioxide, without which unabated warming incurs net costs of up to $18 B, generating benefits to moderate (stringent) mitigation as large as $26 B ($20 B).

    There is growing recognition that implementation of low-carbon policies in urban passenger transport has near-term health co-benefits through increased physical activity and improved air quality. Nevertheless, co-benefits and related cost reductions are often not taken into account in decision processes, likely because they are not easy to capture. In an interdisciplinary multi-model approach we address this gap, investigating the co-benefits resulting from increased physical activity and improved air quality due to climate mitigation policies for three urban areas. Additionally we take a (macro-)economic perspective, since that is the ultimate interest of policy-makers. Methodologically, we link a transport modelling tool, a transport emission model, an emission dispersion model, a health model and a macroeconomic Computable General Equilibrium (CGE) model to analyze three climate change mitigation scenarios. We show that higher levels of physical exercise and reduced exposure to pollutants due to mitigation measures substantially decrease morbidity and mortality. Expenditures are mainly born by the public sector but are mostly offset by the emerging co-benefits. Our macroeconomic results indicate a strong positive welfare effect, yet with slightly negative GDP and employment effects. We conclude that considering economic co-benefits of climate change mitigation policies in urban mobility can be put forward as a forceful argument for policy makers to take action.

  17. A Comprehensive Approach to Climate Change: Options and Obstacles

    Fuglestvedt, J.S.; Skodvin, T.

    1996-06-01

    The main topics of this report are: (1) key elements in the development of a formula for a comprehensive approach to climate change, (2) relations between gases due to atmospheric chemistry interactions and common emission sources, (3) climate effects of existing international agreements on atmospheric emissions, and (4) methods for comparing gases. Building on the text of the climate convention itself, the authors develop an operational definition of a comprehensive approach and list 13 gases which should be included. There are not many adequate methods of comparing gases with different properties. At present the best choice is the Global Warming Potentials method (GWP), although it leaves the environmentally and politically important issue of the time horizon unresolved. An appendix comments on difficulties of including NOx emitted from surface sources in a comprehensive approach under the FCCC (UN`s Framework Convention on Climate Change). 73 refs., 20 figs., 13 tabs.

  18. Global Change Drought in the Southwest: New Management Options

    Udall, B. H.; Overpeck, J. T.

    2015-12-01

    Long held worries about future runoff declines in the Colorado River under climate change are proving to be more than just theory. Fifteen years into this century flows of the Colorado are already declining due mostly to unprecedented temperatures, and as warming proceeds, declines in river flow will grow larger. Temperature-driven droughts, some lasting decades and much more severe than the current 15-year drought, will also become more commonplace if climate change continues unabated. Current projections of future water availability almost universally understate the risk of large Colorado flow reductions under business-as-usual warming. Betting on highly uncertain projections of increased precipitation to overcome even part of the flow reductions due to virtually certain warming is a poor risk management strategy. Many of the existing water policy arrangements in the Colorado River Basin will fail in the 21st century unless innovative new solutions are developed under leadership from the federal government and its basin state partners.

  19. Perception, Mitigation and Adaptation Strategies of Irrigated Paddy Farmer Community to Face Climate Change

    2016-06-01

    Full Text Available Climate change has a real impact on the condition of agriculture in developing countries, including Indonesia. Irrigated paddy farmers are the ones really feeling the impact of climate change. Therefore, we need to understand the perceptions, mitigation and adaptation strategies of irrigated paddy farmer community to face climate change. The study is conducted in Indramayu and Tasikmalaya Regency in West Java by using descriptive survey method, regression analysis and path analysis through Structural Equation Modelling approach with Lisrel TM 8.5. The results showes that: (1 changes to climate variability affects the productivity of rice; (2 perception of irrigated paddy farmer community on climate change and its affects are influenced by internal and external factors; and (3 adaptation strategy are influenced by internal and external factors, whereas no mitigation strategy. Therefore, mitigation and adaptation strategies with site specific location are very necessary improving climate information services, increasing empowerment of farmers through field schools, and providing the provision of facilities that are practical and adaptive to climate.

  20. Limited influence of climate change mitigation on short-term glacier mass loss

    Marzeion, Ben; Kaser, Georg; Maussion, Fabien; Champollion, Nicolas

    2018-04-01

    Glacier mass loss is a key contributor to sea-level change1,2, slope instability in high-mountain regions3,4 and the changing seasonality and volume of river flow5-7. Understanding the causes, mechanisms and time scales of glacier change is therefore paramount to identifying successful strategies for mitigation and adaptation. Here, we use temperature and precipitation fields from the Coupled Model Intercomparison Project Phase 5 output to force a glacier evolution model, quantifying mass responses to future climatic change. We find that contemporary glacier mass is in disequilibrium with the current climate, and 36 ± 8% mass loss is already committed in response to past greenhouse gas emissions. Consequently, mitigating future emissions will have only very limited influence on glacier mass change in the twenty-first century. No significant differences between 1.5 and 2 K warming scenarios are detectable in the sea-level contribution of glaciers accumulated within the twenty-first century. In the long-term, however, mitigation will exert strong control, suggesting that ambitious measures are necessary for the long-term preservation of glaciers.

    Rivers provide a special suite of goods and services valued highly by the public that are inextricably linked to their flow dynamics and the interaction of flow with the landscape. Yet most rivers are within watersheds that are stressed to some extent by human activities including development, dams, or extractive uses. Climate change will add to and magnify risks that are already present through its potential to alter rainfall, temperature, runoff patterns, and to disrupt biological communities and sever ecological linkages. We provide an overview of the predicted impacts based on published studies to date, discuss both reactive and proactive management responses, and outline six categories of management actions that will contribute substantially to the protection of valuable river assets. To be effective, management must be place-based focusing on local watershed scales that are most relevant to management scales. The first priority should be enhancing environmental monitoring of changes and river responses coupled with the development of local scenario-building exercises that take land use and water use into account. Protection of a greater number of rivers and riparian corridors is essential, as is conjunctive groundwater/surface water management. This will require collaborations among multiple partners in the respective river basins and wise land use planning to minimize additional development in watersheds with valued rivers. Ensuring environmental flows by purchasing or leasing water rights and/or altering reservoir release patterns will be needed for many rivers. Implementing restoration projects proactively can be used to protect existing resources so that expensive reactive restoration to repair damage associated with a changing climate is minimized. Special attention should be given to diversifying and replicating habitats of special importance and to monitoring populations at high risk or of special value so that management interventions can occur if the

  3. Potential Roles of Swedish Forestry in the Context of Climate Change Mitigation

    2014-03-01

    Full Text Available In Sweden, where forests cover more than 60% of the land area, silviculture and the use of forest products by industry and society play crucial roles in the national carbon balance. A scientific challenge is to understand how different forest management and wood use strategies can best contribute to climate change mitigation benefits. This study uses a set of models to analyze the effects of different forest management and wood use strategies in Sweden on carbon dioxide emissions and removals through 2105. If the present Swedish forest use strategy is continued, the long-term climate change mitigation benefit will correspond to more than 60 million tons of avoided or reduced emissions of carbon dioxide annually, compared to a scenario with similar consumption patterns in society but where non-renewable products are used instead of forest-based products. On average about 470 kg of carbon dioxide emissions are avoided for each cubic meter of biomass harvested, after accounting for carbon stock changes, substitution effects and all emissions related to forest management and industrial processes. Due to Sweden’s large export share of forest-based products, the climate change mitigation effect of Swedish forestry is larger abroad than within the country. The study also shows that silvicultural methods to increase forest biomass production can further reduce net carbon dioxide emissions by an additional 40 million tons of per year. Forestry’s contribution to climate change mitigation could be significantly increased if management of the boreal forest were oriented towards increased biomass production and if more wood were used to substitute fossil fuels and energy-intensive materials.

    Highlights: • Analyze contiguous U.S. hydropower generation under various emissions scenarios. • Employ systems model that allocates water to competing uses in 2119 river basins. • Average U.S. generation increases under climate change, but falls under low flows. • Mitigation benefits are $2-$4 billion/year due to high values of carbon-free energy. - Abstract: Climate change will have potentially significant effects on hydropower generation due to changes in the magnitude and seasonality of river runoff and increases in reservoir evaporation. These physical impacts will in turn have economic consequences through both producer revenues and consumer expenditures. We analyze the physical and economic effects of changes in hydropower generation for the contiguous U.S. in futures with and without global-scale greenhouse gas (GHG) mitigation, and across patterns from 18 General Circulation Models. Using a monthly water resources systems model of 2119 river basins that routes simulated river runoff through reservoirs, and allocates water to potentially conflicting and climate dependent demands, we provide a first-order estimate of the impacts of various projected emissions outcomes on hydropower generation, and monetize these impacts using outputs from an electric sector planning model for over 500 of the largest U.S. hydropower facilities. We find that, due to generally increasing river runoff under higher emissions scenarios in the Pacific Northwest, climate change tends to increase overall hydropower generation in the contiguous U.S. During low flow months, generation tends to fall with increasing emissions, potentially threatening the estimated low flow, firm energy from hydropower. Although global GHG mitigation slows the growth in hydropower generation, the higher value placed on carbon-free hydropower leads to annual economic benefits ranging from $1.8 billion to $4.3 billion. The present value of these benefits to the U.S. from global greenhouse gas

  5. Unprecedented rates of land-use transformation in modeled climate change mitigation pathways

    2017-12-01

    Integrated assessment models (IAMs) generate climate change mitigation scenarios consistent with global temperature targets. To limit warming to 2°, stylized cost-effective mitigation pathways rely on extensive deployments of carbon dioxide (CO2) removal (CDR) technologies, including multi-gigatonne yearly carbon removal from the atmosphere through bioenergy with carbon capture and storage (BECCS) and afforestation/reforestation. These assumed CDR deployments keep ambitious temperature limits in reach, but associated rates of land-use transformation have not been evaluated. For IAM scenarios from the IPCC Fifth Assessment Report, we compare rates of modeled land-use conversion to recent observed commodity crop expansions. In scenarios with a likely chance of limiting warming to 2° in 2100, the rate of energy cropland expansion supporting BECCS exceeds past commodity crop rates by several fold. In some cases, mitigation scenarios include abrupt reversal of deforestation, paired with massive afforestation/reforestation. Specifically, energy cropland in crop. If energy cropland instead increases at rates equal to recent soybean and oil palm expansions, the scale of CO2 removal possible with BECCS is 2.6 to 10-times lower, respectively, than the deployments <2° IAM scenarios rely upon in 2100. IAM mitigation pathways may favor multi-gigatonne biomass-based CDR given undervalued sociopolitical and techno-economic deployment barriers. Heroic modeled rates for land-use transformation imply that large-scale biomass-based CDR is not an easy solution to the climate challenge.

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: In a framework where no common forestry policy exists at the EU level (such as the Common Agriculture Policy for agriculture), this report lists EU policies that have an impact on climate change mitigation that can be achieved by the forestry sector. With the objective of analyzing the coherence of these policies, we have established a typology and a hierarchy firstly by laying out the legal status and the financial and institutional resources associated with each policy, and secondly by reviewing the objectives of each policy in regards to climate change mitigation in the forestry sector. We finally analyze potentials synergies and conflicts between them

    The world population is currently about 6.5 billion and expected to reach 9 billion by 2050.This population increase and economic development will bring dramatic increase of energy demand in all over the world, especially in developing countries. Global electricity demand grows at 2.4% per year. To meet this growth, the worlds electricity generating capacity grows from about 3700 G We in 2004 to 7303 G We in 2030.The world may run short of fossil fuels, in particular oil. The protection of the global environment including the reduction of carbon dioxide emissions will be an important issue also. Nuclear energy is clean, safe, reliable and cost-effective, with many environmental benefits. It does not emit greenhouse gases that contribute to climate change, or combustion products and acid gases that cause air , water resource and land pollution. As of 14 January 2008 there were 439 nuclear power plants in operation around the world. They total about 372 G We of generating capacity and supply about 16% of the world electricity, 7 % of global energy. The present article briefly summaries the environmental aspects of the nuclear power and varies factors which support the attractiveness of it for many countries all over the world.

  8. Nature-based solutions to climate change mitigation and adaptation in urban areas: perspectives on indicators, knowledge gaps, barriers, and opportunities for action

    Nadja Kabisch

    2016-06-01

    Full Text Available Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps. In addition, we explore existing barriers and potential opportunities for increasing the scale and effectiveness of nature-based solution implementation. The results were derived from an inter- and transdisciplinary workshop with experts from research, municipalities, policy, and society. As an outcome of the workshop discussions and building on existing evidence, we highlight three main needs for future science and policy agendas when dealing with nature-based solutions: (i produce stronger evidence on nature-based solutions for climate change adaptation and mitigation and raise awareness by increasing implementation; (ii adapt for governance challenges in implementing nature-based solutions by using reflexive approaches, which implies bringing together new networks of society, nature-based solution ambassadors, and practitioners; (iii consider socio-environmental justice and social cohesion when implementing nature-based solutions by using integrated governance approaches that take into account an integrative and transdisciplinary participation of diverse actors. Taking these needs into account, nature-based solutions can serve as climate mitigation and adaptation tools that produce additional cobenefits for societal well-being, thereby serving as strong investment options for sustainable urban planning.

  9. Composting projects under the Clean Development Mechanism: Sustainable contribution to mitigate climate change

    Rogger, Cyrill; Beaurain, Francois; Schmidt, Tobias S.

    2011-01-01

    The Clean Development Mechanism (CDM) of the Kyoto Protocol aims to reduce greenhouse gas emissions in developing countries and at the same time to assist these countries in sustainable development. While composting as a suitable mitigation option in the waste sector can clearly contribute to the former goal there are indications that high rents can also be achieved regarding the latter. In this article composting is compared with other CDM project types inside and outside the waste sector with regards to both project numbers and contribution to sustainable development. It is found that, despite the high number of waste projects, composting is underrepresented and a major reason for this fact is identified. Based on a multi-criteria analysis it is shown that composting has a higher potential for contribution to sustainable development than most other best in class projects. As these contributions can only be assured if certain requirements are followed, eight key obligations are presented.

  12. Energy technology roll-out for climate change mitigation: A multi-model study for Latin America

    van der Zwaan, Bob; Kober, Tom; Calderon, Silvia; Clarke, Leon; Daenzer, Katie; Kitous, Alban; Labriet, Maryse; Lucena, André F. P.; Octaviano, Claudia; Di Sbroiavacca, Nicolas

    2016-05-01

    In this paper we investigate opportunities for energy technology deployment under climate change mitigation efforts in Latin America. Through several carbon tax and CO2 abatement scenarios until 2050 we analyze what resources and technologies, notably for electricity generation, could be cost-optimal in the energy sector to significantly reduce CO2 emissions in the region. By way of sensitivity test we perform a cross-model comparison study and inspect whether robust conclusions can be drawn across results from different models as well as different types of models (general versus partial equilibrium). Given the abundance of biomass resources in Latin America, they play a large role in energy supply in all scenarios we inspect. This is especially true for stringent climate policy scenarios, for instance because the use of biomass in power plants in combination with CCS can yield negative CO2 emissions. We find that hydropower, which today contributes about 800 TWh to overall power production in Latin America, could be significantly expanded to meet the climate policies we investigate, typically by about 50%, but potentially by as much as 75%. According to all models, electricity generation increases exponentially with a two- to three-fold expansion between 2010 and 2050.Wefind that in our climate policy scenarios renewable energy overall expands typically at double-digit growth rates annually, but there is substantial spread in model results for specific options such as wind and solar power: the climate policies that we simulate raise wind power in 2050 on average to half the production level that hydropower provides today, while they raise solar power to either a substantially higher or a much lower level than hydropower supplies at present, depending on which model is used. Also for CCS we observe large diversity in model outcomes, which reflects the uncertainties with regard to its future implementation potential as a result of

  13. Carbon stock corridors to mitigate climate change and promote biodiversity in the tropics

    Jantz, Patrick; Goetz, Scott; Laporte, Nadine

    2014-02-01

    A key issue in global conservation is how biodiversity co-benefits can be incorporated into land use and climate change mitigation activities, particularly those being negotiated under the United Nations to reduce emissions from tropical deforestation and forest degradation. Protected areas have been the dominant strategy for tropical forest conservation and they have increased substantially in recent decades. Avoiding deforestation by preserving carbon stored in vegetation between protected areas provides an opportunity to mitigate the effects of land use and climate change on biodiversity by maintaining habitat connectivity across landscapes. Here we use a high-resolution data set of vegetation carbon stock to map corridors traversing areas of highest biomass between protected areas in the tropics. The derived corridors contain 15% of the total unprotected aboveground carbon in the tropical region. A large number of corridors have carbon densities that approach or exceed those of the protected areas they connect, suggesting these are suitable areas for achieving both habitat connectivity and climate change mitigation benefits. To further illustrate how economic and biological information can be used for corridor prioritization on a regional scale, we conducted a multicriteria analysis of corridors in the Legal Amazon, identifying corridors with high carbon, high species richness and endemism, and low economic opportunity costs. We also assessed the vulnerability of corridors to future deforestation threat.

  14. Implementing climate change mitigation in health services: the importance of context.

    Desmond, Sharon

    2016-10-01

    Academic interest in strategies to reduce the impact of health services on climate change is quickening. Research has largely focused on local innovations with little consideration of the contextual and systemic elements that influence sustainable development across health systems. A realistic framework specifically to guide decision-making by health care providers is still needed. To address this deficit, the literature is explored in relation to health services and climate change mitigation strategies, and the contextual factors that influence efforts to mitigate climate effects in health service delivery environments are highlighted. A conceptual framework is proposed that offers a model for the pursuit of sustainable development practice in health services. A set of propositions is advanced to provide a systems approach to assist decision-making by decoding the challenges faced in implementing sustainable health services. This has important implications for health care providers, funders and legislators since the financial, policy and regulatory environment of health care, along with its leadership and models of care generally conflict with carbon literacy and climate change mitigation strategies. © The Author(s) 2016.

  15. Greenhouse Gas Mitigation Options in ISEEM Global Energy Model: 2010-2050 Scenario Analysis for Least-Cost Carbon Reduction in Iron and Steel Sector

    Karali, Nihan; Xu, Tengfang; Sathaye, Jayant

    2013-12-01

    The goal of the modeling work carried out in this project was to quantify long-term scenarios for the future emission reduction potentials in the iron and steel sector. The main focus of the project is to examine the impacts of carbon reduction options in the U.S. iron and steel sector under a set of selected scenarios. In order to advance the understanding of carbon emission reduction potential on the national and global scales, and to evaluate the regional impacts of potential U.S. mitigation strategies (e.g., commodity and carbon trading), we also included and examined the carbon reduction scenarios in China’s and India’s iron and steel sectors in this project. For this purpose, a new bottom-up energy modeling framework, the Industrial Sector Energy Efficiency Modeling (ISEEM), (Karali et al. 2012) was used to provide detailed annual projections starting from 2010 through 2050. We used the ISEEM modeling framework to carry out detailed analysis, on a country-by-country basis, for the U.S., China’s, and India’s iron and steel sectors. The ISEEM model applicable to iron and steel section, called ISEEM-IS, is developed to estimate and evaluate carbon emissions scenarios under several alternative mitigation options - including policies (e.g., carbon caps), commodity trading, and carbon trading. The projections will help us to better understand emission reduction potentials with technological and economic implications. The database for input of ISEEM-IS model consists of data and information compiled from various resources such as World Steel Association (WSA), the U.S. Geological Survey (USGS), China Steel Year Books, India Bureau of Mines (IBM), Energy Information Administration (EIA), and recent LBNL studies on bottom-up techno-economic analysis of energy efficiency measures in the iron and steel sector of the U.S., China, and India, including long-term steel production in China. In the ISEEM-IS model, production technology and manufacturing details are

    Climate change is one of the great challenges of the 21st century. Its most severe impacts may still be avoided if efforts are made to transform current energy systems. Renewable energy sources have a large potential to displace emissions of greenhouse gases from the combustion of fossil fuels and thereby to mitigate climate change. If implemented properly, renewable energy sources can contribute to social and economic development, to energy access, to a secure and sustainable energy supply, and to a reduction of negative impacts of energy provision on the environment and human health. This Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN) impartially assesses the scientific literature on the potential role of renewable energy in the mitigation of climate change for policymakers, the private sector, academic researchers and civil society. It covers six renewable energy sources - bioenergy, direct solar energy, geothermal energy, hydropower, ocean energy and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. The authors also compare the levelized cost of energy from renewable energy sources to recent non-renewable energy costs. (Author)

  18. Why do some people do "more" to mitigate climate change than others? Exploring heterogeneity in psycho-social associations.

    Ortega-Egea, José Manuel; García-de-Frutos, Nieves; Antolín-López, Raquel

    2014-01-01

    The urgency of climate change mitigation calls for a profound shift in personal behavior. This paper investigates psycho-social correlates of extra mitigation behavior in response to climate change, while also testing for potential (unobserved) heterogeneity in European citizens' decision-making. A person's extra mitigation behavior in response to climate change is conceptualized--and differentiated from common mitigation behavior--as some people's broader and greater levels of behavioral engagement (compared to others) across specific self-reported mitigation actions and behavioral domains. Regression analyses highlight the importance of environmental psychographics (i.e., attitudes, motivations, and knowledge about climate change) and socio-demographics (especially country-level variables) in understanding extra mitigation behavior. By looking at the data through the lens of segmentation, significant heterogeneity is uncovered in the associations of attitudes and knowledge about climate change--but not in motivational or socio-demographic links--with extra mitigation behavior in response to climate change, across two groups of environmentally active respondents. The study has implications for promoting more ambitious behavioral responses to climate change, both at the individual level and across countries.

  19. Mitigation of climate change impacts on raptors by behavioural adaptation: ecological buffering mechanisms

    Wichmann, Matthias C.; Groeneveld, Jürgen; Jeltsch, Florian; Grimm, Volker

    2005-07-01

    The predicted climate change causes deep concerns on the effects of increasing temperatures and changing precipitation patterns on species viability and, in turn, on biodiversity. Models of Population Viability Analysis (PVA) provide a powerful tool to assess the risk of species extinction. However, most PVA models do not take into account the potential effects of behavioural adaptations. Organisms might adapt to new environmental situations and thereby mitigate negative effects of climate change. To demonstrate such mitigation effects, we use an existing PVA model describing a population of the tawny eagle ( Aquila rapax) in the southern Kalahari. This model does not include behavioural adaptations. We develop a new model by assuming that the birds enlarge their average territory size to compensate for lower amounts of precipitation. Here, we found the predicted increase in risk of extinction due to climate change to be much lower than in the original model. However, this "buffering" of climate change by behavioural adaptation is not very effective in coping with increasing interannual variances. We refer to further examples of ecological "buffering mechanisms" from the literature and argue that possible buffering mechanisms should be given due consideration when the effects of climate change on biodiversity are to be predicted.

  20. Nuclear power forms an important pillar of many countries’ climate change mitigation strategies

    Gaspar, Miklos; Sadler, Julie

    2015-01-01

    The need for climate change mitigation is a salient reason for an increasing number of countries considering nuclear power within their national energy portfolios, according to IAEA experts and government sources. “Concerns about climate change is one of the drivers for countries to introduce or to expand their use of nuclear power,” said David Shropshire, Head of the IAEA’s Planning and Economic Studies Section. Other factors include growing energy demands and the desire to increase energy security and reduce dependence on volatile fossil fuel costs, he added.

  1. Dynamics and climate change mitigation potential of soil organic carbon sequestration.

    Sommer, Rolf; Bossio, Deborah

    2014-11-01

    When assessing soil organic carbon (SOC) sequestration and its climate change (CC) mitigation potential at global scale, the dynamic nature of soil carbon storage and interventions to foster it should be taken into account. Firstly, adoption of SOC-sequestration measures will take time, and reasonably such schemes could only be implemented gradually at large-scale. Secondly, if soils are managed as carbon sinks, then SOC will increase only over a limited time, up to the point when a new SOC equilibrium is reached. This paper combines these two processes and predicts potential SOC sequestration dynamics in agricultural land at global scale and the corresponding CC mitigation potential. Assuming that global governments would agree on a worldwide effort to gradually change land use practices towards turning agricultural soils into carbon sinks starting 2014, the projected 87-year (2014-2100) global SOC sequestration potential of agricultural land ranged between 31 and 64 Gt. This is equal to 1.9-3.9% of the SRES-A2 projected 87-year anthropogenic emissions. SOC sequestration would peak 2032-33, at that time reaching 4.3-8.9% of the projected annual SRES-A2 emission. About 30 years later the sequestration rate would have reduced by half. Thus, SOC sequestration is not a C wedge that could contribute increasingly to mitigating CC. Rather, the mitigation potential is limited, contributing very little to solving the climate problem of the coming decades. However, we deliberately did not elaborate on the importance of maintaining or increasing SOC for sustaining soil health, agro-ecosystem functioning and productivity; an issue of global significance that deserves proper consideration irrespectively of any potential additional sequestration of SOC.

  2. The economic potential of bioenergy for climate change mitigation with special attention given to implications for the land system

    Biomass from cellulosic bioenergy crops is expected to play a substantial role in future energy systems, especially if climate policy aims at stabilizing greenhouse gas concentration at low levels. However, the potential of bioenergy for climate change mitigation remains unclear due to large uncertainties about future agricultural yield improvements and land availability for biomass plantations. This letter, by applying a modelling framework with detailed economic representation of the land and energy sector, explores the cost-effective contribution of bioenergy to a low-carbon transition, paying special attention to implications for the land system. In this modelling framework, bioenergy competes directly with other energy technology options on the basis of costs, including implicit costs due to biophysical constraints on land and water availability. As a result, we find that bioenergy from specialized grassy and woody bioenergy crops, such as Miscanthus or poplar, can contribute approximately 100 EJ in 2055 and up to 300 EJ of primary energy in 2095. Protecting natural forests decreases biomass availability for energy production in the medium, but not in the long run. Reducing the land available for agricultural use can partially be compensated for by means of higher rates of technological change in agriculture. In addition, our trade-off analysis indicates that forest protection combined with large-scale cultivation of dedicated bioenergy is likely to affect bioenergy potentials, but also to increase global food prices and increase water scarcity. Therefore, integrated policies for energy, land use and water management are needed.

  4. Engaging Climate Change Mitigation Strategies as Citizen-Scientists at SUNY College at Oneonta

    Ellis, T. D.; McEnroe, N. A.

    2009-12-01

    At SUNY College at Oneonta, we have developed a new course on Global Climate Change that seeks to educate students on the science and policy considerations related to the ongoing discussion of the causes and effects of climatic change. In this course, taught by the Department of Earth Sciences, we engage not only the science behind how and why the climate is changing, but there is a curricular emphasis on improving how we communicate about climate change science. Class activities include developing personal action plans that include evaluation of how effective their plans will be and the challenges they will face; a mock town-hall meeting that will help student-scientists put themselves into different roles in the community and attempt to see things from different perspectives, and a term-project where students will go in-depth on a proposed mitigation plan (local, regional, national, or international), weigh the pros and cons, and recommend a course of action in terms that a lay person can understand. Our goal is to produce citizen-scientists who can communicate more effectively in public about the science and the stakes of mitigating climate change.

    Climate change is expected to alter future temperature and discharge regimes of rivers. These regimes have a strong influence on the life history of most aquatic river species, and are key variables controlling the growth and survival of Atlantic salmon. This study explores how the future abundance of Atlantic salmon may be influenced by climate-induced changes in water temperature and discharge in a regulated river, and investigates how negative impacts in the future can be mitigated by applying different regulated discharge regimes during critical periods for salmon survival. A spatially explicit individual-based model was used to predict juvenile Atlantic salmon population abundance in a regulated river under a range of future water temperature and discharge scenarios (derived from climate data predicted by the Hadley Centre's Global Climate Model (GCM) HadAm3H and the Max Plank Institute's GCM ECHAM4), which were then compared with populations predicted under control scenarios representing past conditions. Parr abundance decreased in all future scenarios compared to the control scenarios due to reduced wetted areas (with the effect depending on climate scenario, GCM, and GCM spatial domain). To examine the potential for mitigation of climate change-induced reductions in wetted area, simulations were run with specific minimum discharge regimes. An increase in abundance of both parr and smolt occurred with an increase in the limit of minimum permitted discharge for three of the four GCM/GCM spatial domains examined. This study shows that, in regulated rivers with upstream storage capacity, negative effects of climate change on Atlantic salmon populations can potentially be mitigated by release of water from reservoirs during critical periods for juvenile salmon.

    2011-01-01

    The impacts of the availability of low-carbon technologies on the regional distribution of mitigation costs are analyzed in a global multi-regional integrated assessment model. Three effects on regional consumption losses are distinguished: domestic measures, trade of fossil energy carriers and trade of emission permits. Key results are: (i) GDP losses and a redirection of investments in the energy system towards capital-intensive technologies are major contributions to regional consumption losses. (ii) A devaluation of tradable fossil energy endowments contributes largely to the mitigation costs of fossil fuel exporters. (iii) In case of reduced availability of low-carbon technologies, the permit market volume and associated monetary redistributions increase. The results suggest that the availability of a broad portfolio of low-carbon technologies could facilitate negotiations on the permit allocation scheme in a global cap-and-trade system. - Highlights: → We analyze the distribution of climate change mitigation costs among world regions. → We quantify contributions from various effects on regional costs. → The interference of world trade and low-carbon technologies is essential. → A broad portfolio of technologies helps international negotiations.

  8. Public attention to science and political news and support for climate change mitigation

    Hart, P. Sol; Nisbet, Erik C.; Myers, Teresa A.

    2015-06-01

    We examine how attention to science and political news may influence public knowledge, perceived harm, and support for climate mitigation policies. Previous research examining these relationships has not fully accounted for how political ideology shapes the mental processes through which the public interprets media discourses about climate change. We incorporate political ideology and the concept of motivated cognition into our analysis to compare and contrast two prominent models of opinion formation, the scientific literacy model, which posits that disseminating scientific information will move public opinion towards the scientific consensus, and the motivated reasoning model, which posits that individuals will interpret information in a biased manner. Our analysis finds support for both models of opinion formation with key differences across ideological groups. Attention to science news was associated with greater perceptions of harm and knowledge for conservatives, but only additional knowledge for liberals. Supporting the literacy model, greater knowledge was associated with more support for climate mitigation for liberals. In contrast, consistent with motivated reasoning, more knowledgeable conservatives were less supportive of mitigation policy. In addition, attention to political news had a negative association with perceived harm for conservatives but not for liberals.

  9. Strategic and legal framework in forestry and related sectors: Climate change mitigation in European Union and Serbia

    Ranković Nenad

    2016-01-01

    Full Text Available The important role of forests in mitigating and adapting to climate changes is recognized and widely accepted. Therefore, it becomes a subject of universal interest and support. However, in the national strategies relating to climate change, the importance of the forestry sector in mitigating these changes is quite often not discussed in detail. In addition, the problem of climate change is not fully represented and included in national forestry policies. The aim of this research was to determine the compliance and differences of strategic and legislative frameworks in forestry and related sectors, relating to climate change mitigation in the EU and Serbia. At the EU level, there are two strategies and a policy framework, and in Serbia, eight sectoral strategies, referring and discussing the climate change mitigation through forestry. At the same time, these issues are highlighted as the primary objective, only in the Climate and Energy Package of the EU and the Forestry Development Strategy in Serbia. In terms of legislative framework in Serbia, two laws have climate change mitigation through forestry as the primary objective, while for the analyzed relevant EU legislation, this is a secondary objective. In Serbia, only the Forest law has a direct impact on climate change mitigation through forestry, while at EU level, there is no regulation, directive or communication, with the same direct influence.

  10. Financialization impedes climate change mitigation: Evidence from the early American solar industry.

    Jerneck, Max

    2017-03-01

    The article investigates how financialization impedes climate change mitigation by examining its effects on the early history of one low-carbon industry, solar photovoltaics in the United States. The industry grew rapidly in the 1970s, as large financial conglomerates acquired independent firms. While providing needed financial support, conglomerates changed the focus from existing markets in consumer applications toward a future utility market that never materialized. Concentration of the industry also left it vulnerable to the corporate restructuring of the 1980s, when the conglomerates were dismantled and solar divisions were pared back or sold off to foreign firms. Both the move toward conglomeration, when corporations became managed as stock portfolios, and its subsequent reversal were the result of increased financial dominance over corporate governance. The American case is contrasted with the more successful case of Japan, where these changes to corporate governance did not occur. Insulated from shareholder pressure and financial turbulence, Japanese photovoltaics manufacturers continued to expand investment throughout the 1980s when their American rivals were cutting back. The study is informed by Joseph Schumpeter's theory of creative destruction and Hyman Minsky's theory of financialization, along with economic sociology. By highlighting the tenuous and conflicting relation between finance and production that shaped the early history of the photovoltaics industry, the article raises doubts about the prevailing approach to mitigate climate change through carbon pricing. Given the uncertainty of innovation and the ease of speculation, it will do little to spur low-carbon technology development without financial structures supporting patient capital.

  11. Climate change mitigation: the potential of agriculture as a renewable energy source in Nigeria.

    Elum, Z A; Modise, D M; Nhamo, G

    2017-02-01

    Energy is pivotal to the economic development of every nation. However, its production and utilization leads to undesirable carbon emissions that aggravate global warming which results in climate change. The agriculture sector is a significant user of energy. However, it has the potential to be a major contributor to Nigeria's energy supply mix in meeting its energy deficit. More so, in the light of current and impending adverse effects of climate change, there is a need to contain GHG's emissions. This paper focuses on bioenergy utilization as a climate change mitigation strategy and one that can, through effective waste management, enhance sustainable economic development in Nigeria. The paper employed a critical discourse analysis to examine the potential of the agricultural sector to provide biofuels from energy crops and other biomass sources. We conclude that Nigeria can reduce its GHG emissions and greatly contribute to global climate change mitigation while also alleviating its energy supply deficit if the agricultural and municipal wastes readily available in its towns and cities are converted to bioenergy. Such engagements will not only promote a clean and healthy environment but also create jobs for economic empowerment and a better standard of living for the people.

  12. Perspectives on global climate change: A review of the adaptation and mitigation approaches

    Morrisette, P.M.

    1992-01-01

    This paper was prepared for the conference on Global Climate Change and International Security sponsored by the Midwest Consortium for International Security Studies of the American Academy of Arts and Sciences and held in Chicago, Illinois on February 11-13, 1992. The purpose of the paper is to provide some background on the different perceptions and perspectives that are presently shaping the policy debate on how to respond to the problem of global warming. For better or worse, this debate has focused primarily on whether to adapt to climate change in the future or to mitigate climate change in the present, and as the issue has become increasingly political this debate has become polarized. The two approaches, as this paper notes, are not mutually exclusive; in fact, they share much in common. Differences, however, can be found in how proponents of each view the risks of global climate change. This paper provides a brief outline of the progression of global warming from an obscure scientific concern into a leading international political issue, reviews previous efforts by social scientists to assess attitudes and positions on global warming, and examines in detail the adaptation and mitigation perspectives and assesses how they differ on the basis of different conceptions of uncertainty and risk, equity, and technology

    2017-07-01

    Full Text Available A rise in the shallow unconfined groundwater at a site in Australia is causing water logging of the underground facility in the affected area. Realizing this problem, a study was conducted to identify the source of water that is causing the rise and to develop an implementation and operation plan of the mitigation (dewatering system. Modelling was undertaken using MODFLOW-SURFACT code, within the framework of Visual MODFLOW, to assess the spatial and temporal groundwater level at the site. The study undertaken incorporates compilation and assessment of available data, including a list of factual information reviewed, development of a conceptual groundwater model for the site and modelling of the pre and post development conditions. The outcomes of the assessment indicate water level rises due to the construction of the embankment are likely less than 0.12 m and changes in land, such as affected area burial, may change aquifer characteristics more significantly than the embankment. It is concluded that the elevated groundwater levels in the affected area are most likely a result of above average rainfall since 2007 and long term cumulative land use changes. The embankment construction is just one of many land use changes that have occurred both within and surrounding the affected area and likely only a minor contributor to the elevated water levels. Greater contribution may be attributed to re-direction of the natural flow paths the railway culvert weir reducing the overland flow gradient and ongoing changes (burial within the affected area and including the embankment. The model findings gives answers on what factors may be/are causing/contributing to, the higher than usual groundwater levels in the study area. A combination of drainage and/or pumping (dewatering system is suggested as a solution to overcome the problem of rising groundwater levels at the site. Further, the model output can aid in assessing mitigation options, including

    greenhouse gas emission, yet technologies need for have not been assessed. The technology needs assessment for the agriculture sector cover paddy field, perennial crops, peat soil, and livestock. The concern of the assessment is categorized into technology options, priority/key technology, barriers, and modalities. Selected technologies are based on criteria and priority options of technology needs. Data and information have been collected from related agencies, center, institutes and other relevant sources as well as through a workshop. Technology selection process for mitigation considered general criteria of reducing GHG emissions from crops and livestock, promoting resource conservation, promoting sustainable biodiversity, promoting green energy, sustaining food security, and promoting energy alternative; and specific criteria of promoting local technology for mitigation, sustaining site-specific germ plasms, promoting simple and cheap technology for poor farmers, promoting less emission crop varieties, substituting chemical with organic fertilizers/compost, and reduce CH4 emissions. Those criteria are scored into 4 classes, i.e. high value/high relevant/high impact (score: 5, Medium value/relevant/med impact (score: 3; Low value/less relevant/less impact (score: 1; nil – not relevant/no impact (score: 0. The assessment has come up with the results that priority technologies needed for mitigation are (a low methane emitter crops varieties, appropriate fertilizing, no tillage, and intermittent irrigation for paddy fields, (b appropriate slash and burn and bio-fuel for perennial crops, (c composting manure and biogas production for livestock, and (d overcoming slash and burn, avoiding over drain and maintaining soil moisture for peat soils.

    China is quickly building up its nuclear power capacity while the hailed nuclear renaissance in the United States has been largely stagnant. The political and industrial structures explain the divergent paths. This paper draws lessons from the French experiences in deploying nuclear power and uses the lessons in comparing Chinese and U.S. policies. An authoritative political system and state-owned utility industry allow China to emulate the French approaches such as government-backed financing and broad-scale deployment with standardized design. The democratic political system and fragmented utility industry, and the laissez-faire ideology in the United States, on the other hand, are unfavorable to a nuclear renaissance. The prospect of a nuclear revival in the United States remains highly uncertain. As China builds up its nuclear industry, it will be able to reduce carbon emissions without a carbon price through a national plan to deploy low-carbon nuclear electricity, while the United States cannot implement a climate policy without a carbon price. American politicians should stop using China's lack of carbon cap as an excuse for postponing the legislation of a carbon price. - Highlights: > The Chinese government and Chinese state-owned companies are indigenizing nuclear power technologies, establishing nuclear manufacturing capacity, and gradually scaling up nuclear power deployment. > China is likely on a path to the biggest nuclear buildup in human history. > The hailed nuclear renaissance in the United States has been largely stagnant. > The underlying causes of U.S. Nuclear stagnation is rooted in the democratic political system and fragmented utility industry, and the laissez-faire ideology, which are unlikely to change in the foreseeable future. > China can move toward a low-carbon electricity system without a carbon price.

    2009-01-01

    Wind power can help mitigate climate change. Computational fluid dynamics (CFD) is used here to simulate and analyze the Zephyr vertical axis wind turbine and to assess how it reduces greenhouse gas emissions. Fluid flow through the turbine is simulated to predict its performance. A multiple reference frame model capability of CFD is used to express the turbine power output as a function of the wind free stream velocity and the rotor rotational speed. The results suggest the wind turbine could significantly reduce energy demand and greenhouse gas emissions in urban and rural settings relative to conventional power systems. (author)

    We present results from multiple comprehensive models used to simulate an aggressive mitigation scenario based on detailed results of an Integrated Assessment Model. The experiment employs ten global climate and Earth System models (GCMs and ESMs) and pioneers elements of the long-term experimental design for the forthcoming 5th Intergovernmental Panel on Climate Change assessment. Atmospheric carbon-dioxide concentrations pathways rather than carbon emissions are specified in all models, including five ESMs that contain interactive carbon cycles. Specified forcings also include minor greenhouse gas concentration pathways, ozone concentration, aerosols (via concentrations or precursor emissions) and land use change (in five models). The new aggressive mitigation scenario (E1), constructed using an integrated assessment model (IMAGE 2.4) with reduced fossil fuel use for energy production aimed at stabilizing global warming below 2 K, is studied alongside the medium-high non-mitigation scenario SRES A1B. Resulting twenty-first century global mean warming and precipitation changes for A1B are broadly consistent with previous studies. In E1 twenty-first century global warming remains below 2 K in most models, but global mean precipitation changes are higher than in A1B up to 2065 and consistently higher per degree of warming. The spread in global temperature and precipitation responses is partly attributable to inter-model variations in aerosol loading and representations of aerosol-related radiative forcing effects. Our study illustrates that the benefits of mitigation will not be realised in temperature terms until several decades after emissions reductions begin, and may vary considerably between regions. A subset of the models containing integrated carbon cycles agree that land and ocean sinks remove roughly half of present day anthropogenic carbon emissions from the atmosphere, and that anthropogenic carbon emissions must decrease by at least 50% by 2050 relative

    ) within the program SWAT-CUP (SWAT Calibration and Uncertainty Programs). Model performance is assessed against a variety of statistical measures including the Nash-Sutcliffe efficiency coefficient (NSE) and percentage bias (PBIAS). Various mitigation scenarios are modelled within the catchment, including changes in fertiliser application rates and timing and the introduction of different tillage techniques and cover-crop regimes. The effects of the applied measures on water quality are examined and recommendations made on which measures have the greatest potential to be applied within the catchment to improve water quality. This study reports the findings of that analysis and presents techniques by which diffuse agricultural pollution can be reduced within catchments through the implementation of multiple on-farm measures. The methodology presented has the potential to be applied within other catchments, allowing tailored mitigation strategies to be developed. Ultimately, this research provides 'tested' mitigation options that can be applied within the Wensum and similar catchments to improve water quality and to ensure that certain obligatory water quality standards are achieved.

    Full Text Available Climate change is having a growing impact on every human activity, especially on agriculture with altered rainfall patterns and an increased number and intensity of extreme weather events. This article argues that efforts to mitigate and adapt to climate change must consider whole food systems – rather than the sole production of food – whilst embracing a conscious gendered approach. Women are the main victims of hunger, but they are also the main actors of global food systems, they greatly contribute to their household’s and community’s wellbeing and detain a rich and often untapped knowledge of food systems. Promoting the role of women in our global food systems enhances the inclusion of criteria mainly valued by women such as resilience, diversity and nutrition, which are paramount for climate change mitigation and adaptation.   Photo credit: By OxFam East Africa [CC-BY-2.0 (http://creativecommons.org/licenses/by/2.0], via Wikimedia Commons

  1. Climate change mitigation in the Forest Sector: what Happened in Poznan

    Loisel, C.

    2008-01-01

    Climate change mitigation in the forestry sector was an important topic during the recent Climate Convention conference in Poznan (1- 12 December 2008). Forests appeared in various agenda items of the formal negotiations: - under the Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA) concerning policy approaches and positives incentives on issues relating to reducing emissions from deforestation and forest degradation in developing countries; and the role of conservation, sustainable management of forests and enhancement of forest carbon stocks in developing countries ('REDD+'), - under the Subsidiary Body for Scientific and Technological Advice (SBSTA) concerning methodological aspects on the above, - under the Ad Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol (AWG-KP) concerning the treatment of greenhouse gas emissions and removals related to land use, land use change and forestry (LULUCF) in Annex I Parties in the context of post-2012 commitments. This note recalls what happened under these agenda items and also on the margins of formal negotiations in relation to climate change mitigation in the forest sector. (author)

  2. Urban ecosystem modeling and global change: Potential for rational urban management and emissions mitigation

    Chen, Shaoqing; Chen, Bin; Fath, Brian D.

    2014-01-01

    Urbanization is a strong and extensive driver that causes environmental pollution and climate change from local to global scale. Modeling cities as ecosystems has been initiated by a wide range of scientists as a key to addressing challenging problems concomitant with urbanization. In this paper, ‘urban ecosystem modeling (UEM)’ is defined in an inter-disciplinary context to acquire a broad perception of urban ecological properties and their interactions with global change. Furthermore, state-of-the-art models of urban ecosystems are reviewed, categorized as top-down models (including materials/energy-oriented models and structure-oriented models), bottom-up models (including land use-oriented models and infrastructure-oriented models), or hybrid models thereof. Based on the review of UEM studies, a future framework for explicit UEM is proposed based the integration of UEM approaches of different scales, guiding more rational urban management and efficient emissions mitigation. - Highlights: • Urban ecosystems modeling (UEM) is defined in an interdisciplinary context. • State-of-the-art models for UEM are critically reviewed and compared. • An integrated framework for explicit UEM is proposed under global change. - State-of-the-art models of urban ecosystem modeling (UEM) are reviewed for rational urban management and emissions mitigation

  6. Climate change risks and adaptation options across Australian seafood supply chains – A preliminary assessment

    A. Fleming

    2014-01-01

    Full Text Available Climate change is already impacting the biology of the oceans and some dependent industries are in turn responding to these impacts. The development of response options for users of marine resources, such as fishers, is important in guiding adaptation efforts. However, harvesting fish is only the first step in a supply chain that delivers seafood to consumers. Impacts higher up the chain have seldom been considered in fisheries-climate research yet an understanding of these impacts and how climate risks and adaptation information are interpreted and used by stakeholders across the chain is vital for developing viable and sustainable adaptation options. We examined stakeholder perceptions of points where climate change impacts and adaptations currently occur, or may occur in the future, across the supply chains of several Australian fisheries (southern rock lobster, tropical rock lobster, prawn and aquaculture sectors (oyster, aquaculture prawn. We found that climate change impacts are well understood at the harvest stage and there is evidence of potential impacts and disruption to supply chains. Yet, there currently is no strong driver for change higher up the chain. Holistic adaptation planning along the supply chain, underpinned by targeted information and policy for the catch, processing and distribution, and marketing phases is needed. This effort is needed now, as some adaptation options have long lead times, and a delay in adaptation planning may limit future options. Given potential lead times and associated uncertainty, a risk-based approach is recommended with regard to adaptation planning for Australia’s seafood sector.

    While it has been recognized that actions reducing greenhouse gas (GHG) emissions can have significant positive and negative impacts on human health through reductions in ambient fine particulate matter (PM2.5) concentrations, these impacts are rarely taken into account when analyzing specific policies. This study presents a new framework for estimating the change in health outcomes resulting from implementation of specific carbon dioxide (CO2) reduction activities, allowing comparison of different sectors and options for climate mitigation activities. Our estimates suggest that in the year 2020, the reductions in adverse health outcomes from lessened exposure to PM2.5 would yield economic benefits in the range of $6 to $14 billion (in 2008 USD), depending on the specific activity. This equates to between $40 and $93 per metric ton of CO2 in health benefits. Specific climate interventions will vary in the health co-benefits they provide as well as in potential harms that may result from their implementation. Rigorous assessment of these health impacts is essential for guiding policy decisions as efforts to reduce GHG emissions increase in scope and intensity.

  11. Integrating Climate Change Adaptation and Mitigation with Urban planning for a Livable city in Tehran

    Mojtaba Rafieian

    2015-09-01

    Full Text Available Climate change impacts are seen within growing numbers of cities in low- and middle-income countries, so there is growing interest in the adaptation and mitigation plans and programs put forward by city authorities. This paper aims to provide a better understanding of the constraints which cities face them in this subject by analyzing the case of Tehran. City has a commitment to decentralization, transparency, accountability and participation. There are some new programs and plansin urban planning which has evolved to include a broad vision of urban challenges and responses, a commitment to environmental sustainability and a strategic plan that has involved multiple stakeholders. This paper describes the principles for integrating climate change adaptation and mitigation with urban planning which can be useful for urban authorities. Then it analysesthe many measures implemented in Tehran over the last years, which provide a solid foundation for more systematically addressing adaptation. It also describes the significant challenges faced by the city’s administration, especially around funding, data and the challenge of responding to pressing and competing interests.Tehran city is still struggling to complete greenhouse gas inventories andit has, however, implemented several specific mitigation measures and tries continuously to place this issue on the government’s agenda.However, Tehran’s particular way of responding to current development challenges has put in place the flexibility, creativity and commitment needed for adaptation, regardless of whether this is made explicit or not. The results of this study reveal thatTehran’s policies have had continuity and consistency, despite being frequently revised over years, because each administration has built upon the progress of its predecessor. This is quite unusual; it is more common for there to be a revision of all that has been accomplished and for the need to point out the negative

  12. Climate change and climate variability: personal motivation for adaptation and mitigation.

    Semenza, Jan C; Ploubidis, George B; George, Linda A

    2011-05-21

    Global climate change impacts on human and natural systems are predicted to be severe, far reaching, and to affect the most physically and economically vulnerable disproportionately. Society can respond to these threats through two strategies: mitigation and adaptation. Industry, commerce, and government play indispensable roles in these actions but so do individuals, if they are receptive to behavior change. We explored whether the health frame can be used as a context to motivate behavioral reductions of greenhouse gas emissions and adaptation measures. In 2008, we conducted a cross-sectional survey in the United States using random digit dialing. Personal relevance of climate change from health threats was explored with the Health Belief Model (HBM) as a conceptual frame and analyzed through logistic regressions and path analysis. Of 771 individuals surveyed, 81% (n = 622) acknowledged that climate change was occurring, and were aware of the associated ecologic and human health risks. Respondents reported reduced energy consumption if they believed climate change could affect their way of life (perceived susceptibility), Odds Ratio (OR) = 2.4 (95% Confidence Interval (CI): 1.4-4.0), endanger their life (perceived severity), OR = 1.9 (95% CI: 1.1-3.1), or saw serious barriers to protecting themselves from climate change, OR = 2.1 (95% CI: 1.2-3.5). Perceived susceptibility had the strongest effect on reduced energy consumption, either directly or indirectly via perceived severity. Those that reported having the necessary information to prepare for climate change impacts were more likely to have an emergency kit OR = 2.1 (95% CI: 1.4-3.1) or plan, OR = 2.2 (95% CI: 1.5-3.2) for their household, but also saw serious barriers to protecting themselves from climate change or climate variability, either by having an emergency kit OR = 1.6 (95% CI: 1.1-2.4) or an emergency plan OR = 1.5 (95%CI: 1.0-2.2).

    Since 2012, the Mexican government through its National Forestry Commission, with support from the Commission for Environmental Cooperation, the Forest Services of Canada and USA, the SilvaCarbon Program and research institutes in Mexico, has made important progress towards the use of carbon dynamics models ("gain-loss" approach) for greenhouse gas (GHG) emissions monitoring and projections into the future. Here we assess the biophysical mitigation potential of policy alternatives identified by the Mexican Government (e.g. net zero deforestation rate, sustainable forest management) based on a systems approach that models carbon dynamics in forest ecosystems, harvested wood products and substitution benefits in two contrasting states of Mexico. We provide key messages and results derived from the use of the Carbon Budget Model of the Canadian Forest Sector and a harvested wood products model, parameterized with input data from Mexicós National Forest Monitoring System (e.g. forest inventories, remote sensing, disturbance data). The ultimate goal of this tri-national effort is to develop data and tools for carbon assessment in strategic landscapes in North America, emphasizing the need to include multiple sectors and types of collaborators (scientific and policy-maker communities) to design more comprehensive portfolios for climate change mitigation in accordance with the Paris Agreement of the United Nation Framework Convention on Climate Change (e.g. Mid-Century Strategy, NDC goals).

  15. Tooling up urban planning for climate change mitigation in Malaysian cities

    Chau, L W; Yap, Z C; Ho, C S

    2014-01-01

    The city's 2-dimensional spatial structure and 3-dimensional form significantly influence its energy and GHG emission intensity. In rapidly developing urban-regions, the ability of the local planning authorities to quantify the spatial structure and form of existing urban areas, new developments and the emergent urban-region in terms of GHG emission is vital to any effective local, national and global climate change mitigation effort. While a wide array of tools has been developed for assessing built environment sustainability at various spatial scales, these are predominantly eco-efficiency rating tools that do not model the 'spatial structure-GHG' relationship and do not illustrate the GHG implications of urban structure and form, which crucially inform local planning decisions with respect to climate change mitigation. This paper takes the first steps in analysing three spatial-based planning models (Envision Tomorrow, GHGProof, URBEMIS) that estimate GHG emissions towards assessing their adaptability for application in Malaysian cities. It looks into the models' i nner working , unpacking the variables and their relationships; assumptions and conversion rates used; and their data requirement and structure. The models' characteristics and features are critically compared to evaluate their capabilities, limitations and relevance to the Malaysian urban planning context, particularly in terms of data availability

  16. ¨ A Dilemma of Abundance: Governance Challenges of Reconciling Shale Gas Development and Climate Change Mitigation

    Karena Shaw

    2013-05-01

    Full Text Available Shale gas proponents argue this unconventional fossil fuel offers a “bridge” towards a cleaner energy system by offsetting higher-carbon fuels such as coal. The technical feasibility of reconciling shale gas development with climate action remains contested. However, we here argue that governance challenges are both more pressing and more profound. Reconciling shale gas and climate action requires institutions capable of responding effectively to uncertainty; intervening to mandate emissions reductions and internalize costs to industry; and managing the energy system strategically towards a lower carbon future. Such policy measures prove challenging, particularly in jurisdictions that stand to benefit economically from unconventional fuels. We illustrate this dilemma through a case study of shale gas development in British Columbia, Canada, a global leader on climate policy that is nonetheless struggling to manage gas development for mitigation. The BC case is indicative of the constraints jurisdictions face both to reconcile gas development and climate action, and to manage the industry adequately to achieve social licence and minimize resistance. More broadly, the case attests to the magnitude of change required to transform our energy systems to mitigate climate change.

  17. Can Seaweed Farming Play a Role in Climate Change Mitigation and Adaptation?

    Duarte, Carlos M.

    2017-04-12

    Seaweed aquaculture, the fastest-growing component of global food production, offers a slate of opportunities to mitigate, and adapt to climate change. Seaweed farms release carbon that maybe buried in sediments or exported to the deep sea, therefore acting as a CO2 sink. The crop can also be used, in total or in part, for biofuel production, with a potential CO2 mitigation capacity, in terms of avoided emissions from fossil fuels, of about 1,500 tons CO2 km−2 year−1. Seaweed aquaculture can also help reduce the emissions from agriculture, by improving soil quality substituting synthetic fertilizer and when included in cattle fed, lowering methane emissions from cattle. Seaweed aquaculture contributes to climate change adaptation by damping wave energy and protecting shorelines, and by elevating pH and supplying oxygen to the waters, thereby locally reducing the effects of ocean acidification and de-oxygenation. The scope to expand seaweed aquaculture is, however, limited by the availability of suitable areas and competition for suitable areas with other uses, engineering systems capable of coping with rough conditions offshore, and increasing market demand for seaweed products, among other factors. Despite these limitations, seaweed farming practices can be optimized to maximize climate benefits, which may, if economically compensated, improve the income of seaweed farmers.

  18. The potential of Indonesian mangrove forests for global climate change mitigation

    Murdiyarso, Daniel; Purbopuspito, Joko; Kauffman, J. Boone; Warren, Matthew W.; Sasmito, Sigit D.; Donato, Daniel C.; Manuri, Solichin; Krisnawati, Haruni; Taberima, Sartji; Kurnianto, Sofyan

    2015-12-01

    Mangroves provide a wide range of ecosystem services, including nutrient cycling, soil formation, wood production, fish spawning grounds, ecotourism and carbon (C) storage. High rates of tree and plant growth, coupled with anaerobic, water-logged soils that slow decomposition, result in large long-term C storage. Given their global significance as large sinks of C, preventing mangrove loss would be an effective climate change adaptation and mitigation strategy. It has been reported that C stocks in the Indo-Pacific region contain on average 1,023 MgC ha-1 (ref. ). Here, we estimate that Indonesian mangrove C stocks are 1,083 +/- 378 MgC ha-1. Scaled up to the country-level mangrove extent of 2.9 Mha (ref. ), Indonesia’s mangroves contained on average 3.14 PgC. In three decades Indonesia has lost 40% of its mangroves, mainly as a result of aquaculture development. This has resulted in annual emissions of 0.07-0.21 Pg CO2e. Annual mangrove deforestation in Indonesia is only 6% of its total forest loss; however, if this were halted, total emissions would be reduced by an amount equal to 10-31% of estimated annual emissions from land-use sectors at present. Conservation of carbon-rich mangroves in the Indonesian archipelago should be a high-priority component of strategies to mitigate climate change.

  19. Afforestation to mitigate climate change: impacts on food prices under consideration of albedo effects

    Kreidenweis, Ulrich; Humpenöder, Florian; Stevanović, Miodrag; Bodirsky, Benjamin Leon; Kriegler, Elmar; Lotze-Campen, Hermann; Popp, Alexander

    2016-08-01

    Ambitious climate targets, such as the 2 °C target, are likely to require the removal of carbon dioxide from the atmosphere. Afforestation is one such mitigation option but could, through the competition for land, also lead to food prices hikes. In addition, afforestation often decreases land-surface albedo and the amount of short-wave radiation reflected back to space, which results in a warming effect. In particular in the boreal zone, such biophysical warming effects following from afforestation are estimated to offset the cooling effect from carbon sequestration. We assessed the food price response of afforestation, and considered the albedo effect with scenarios in which afforestation was restricted to certain latitudinal zones. In our study, afforestation was incentivized by a globally uniform reward for carbon uptake in the terrestrial biosphere. This resulted in large-scale afforestation (2580 Mha globally) and substantial carbon sequestration (860 GtCO2) up to the end of the century. However, it was also associated with an increase in food prices of about 80% by 2050 and a more than fourfold increase by 2100. When afforestation was restricted to the tropics the food price response was substantially reduced, while still almost 60% cumulative carbon sequestration was achieved. In the medium term, the increase in prices was then lower than the increase in income underlying our scenario projections. Moreover, our results indicate that more liberalised trade in agricultural commodities could buffer the food price increases following from afforestation in tropical regions.

  20. Greenhouse gas emissions from agricultural food production to supply Indian diets: Implications for climate change mitigation.

    Agriculture is a major source of greenhouse gas (GHG) emissions globally. The growing global population is putting pressure on agricultural production systems that aim to secure food production while minimising GHG emissions. In this study, the GHG emissions associated with the production of major food commodities in India are calculated using the Cool Farm Tool. GHG emissions, based on farm management for major crops (including cereals like wheat and rice, pulses, potatoes, fruits and vegetables) and livestock-based products (milk, eggs, chicken and mutton meat), are quantified and compared. Livestock and rice production were found to be the main sources of GHG emissions in Indian agriculture with a country average of 5.65 kg CO 2 eq kg -1 rice, 45.54 kg CO 2 eq kg -1 mutton meat and 2.4 kg CO 2 eq kg -1 milk. Production of cereals (except rice), fruits and vegetables in India emits comparatively less GHGs with foods could greatly increase GHG emissions from Indian agriculture. A range of mitigation options are available that could reduce emissions from current levels and may be compatible with increased future food production and consumption demands in India.

    In recent decades it has become increasingly clear that the global climate is warming and that regional climates are changing. The changes include alterations in rainfall pattern and intensities, sea level, and the frequencies of extreme weather events. Climate changes will not just have global effects, they will also occur regionally. The consequences will be felt and dealt with in our own region. In addition to studies at the European level, a study entitled 'An integrated assessment of vulnerability to climate change and adaptation options in the Netherlands' was carried out

    Under future scenarios of business-as-usual emissions, the ocean storage of anthropogenic carbon is anticipated to decrease because of ocean chemistry constraints and positive feedbacks in the carbon-climate dynamics, whereas it is still unknown how the oceanic carbon cycle will respond to more substantial mitigation scenarios. To evaluate the natural system response to prescribed atmospheric ''target'' concentrations and assess the response of the ocean carbon pool to these values, 2 centennial projection simulations have been performed with an Earth System Model that includes a fully coupled carbon cycle, forced in one case with a mitigation scenario and the other with the SRES A1B scenario. End of century ocean uptake with the mitigation scenario is projected to return to the same magnitude of carbon fluxes as simulated in 1960 in the Pacific Ocean and to lower values in the Atlantic. With A1B, the major ocean basins are instead projected to decrease the capacity for carbon uptake globally as found with simpler carbon cycle models, while at the regional level the response is contrasting. The model indicates that the equatorial Pacific may increase the carbon uptake rates in both scenarios, owing to enhancement of the biological carbon pump evidenced by an increase in Net Community Production (NCP) following changes in the subsurface equatorial circulation and enhanced iron availability from extratropical regions. NCP is a proxy of the bulk organic carbon made available to the higher trophic levels and potentially exportable from the surface layers. The model results indicate that, besides the localized increase in the equatorial Pacific, the NCP of lower trophic levels in the northern Pacific and Atlantic oceans is projected to be halved with respect to the current climate under a substantial mitigation scenario at the end of the twenty-first century. It is thus suggested that changes due to cumulative carbon emissions up to present and the

In general, the combination of earlier reservoir refill with greater storage allocations for instream flow targets mitigated some of the negative impacts to flow, but only with significant losses in firm hydropower production (ranging from -9 percent in Period 1 to -35 percent for RCM). Simulated hydropower revenue changes were less than 5 percent for all scenarios, however, primarily due to small changes in annual runoff.

    This report summarizes the results of the project Projecting future energy demand: Balancing development, energy and climate priorities in large developing economies, which has been managed by UNEP Risoe Centre on behalf of UNEP DTIE. The report argues that starting from development objectives is critical to mitigation efforts in developing countries. Instead of defining local benefits as ancillary to mitigation, reductions of GHG emissions should be seen as the co-benefits of policies that drive local sustainable development. A development-focused approach seems more likely to be implemented than the imposition of GHG targets by the international community - especially as South Africa has adopted development targets such as the Millennium Development Goals and promoted the Johannesburg Plan of Action. The case studies presented take as their starting point development objectives, rather than climate change targets. The form of climate action which it investigates is sustainable development policies and measures. (BA)

    Examining the intersection of risk analysis and sustainable energy strategies reveals numerous examples of energy efficient and renewable energy technologies that offer insurance loss-prevention benefits. The growing threat of climate change provides an added motivation for the risk community to better understand this area of opportunity. While analyses of climate change mitigation typically focus on the emissions-reduction characteristics of sustainable energy technologies, less often recognized are a host of synergistic ways in which these technologies also offer adaptation benefits, e.g. making buildings more resilient to natural disasters. While there is already some relevant activity, there remain various barriers to significantly expanding these efforts. Achieving successful integration of sustainable energy considerations with risk-management objectives requires a more proactive orientation, and coordination among diverse actors and industry groups.

    Greenhouse gas emissions from developing countries will likely surpass those from developed countries within the first half of this century, highlighting the need for developing country efforts to reduce the risk of climate change. While developing nations have been reluctant to accept binding emissions targets, asking that richer nations take action first, many are undertaking efforts that have significantly reduced the growth of their own greenhouse gas emissions. In most cases, climate mitigation is not the goal, but rather an outgrowth of efforts driven by economic, security, or local environmental concerns. This study attempts to document the climate mitigation resulting from such efforts in six key countries (Brazil, China, India, Mexico, South Africa, and Turkey) and to inform policy-making aimed at further mitigation in these and other developing nations. The six countries examined here reflect significant regional, economic, demographic, and energy resource diversity. They include the world's two most populous nations, a major oil exporter, Africa's largest greenhouse gas emitter, and the country with the largest expanse of tropical forest. While their circumstances vary widely, these countries share common concerns that have motivated actions resulting in reduced greenhouse gas emissions growth. Primary among these concerns are economic growth, energy security, and improved air quality. The analysis presented here demonstrates that actions taken by these countries to achieve these and other goals have reduced the growth of their combined annual greenhouse gas emissions over the past three decades by nearly 300 million tons a year. If not for these actions, the annual emissions of these six countries would likely be about 18 percent higher than they are today. To put these figures in perspective, if all developed countries were to meet the emission targets set by the Kyoto Protocol, they would have to reduce their emissions by an estimated 392

    This study has the main purpose to make useful information available for the programming of the Knowledge for Climate (KfC) program. The emphasis has been laid on a broad overview of mitigation options and relations, complemented with more detailed information on new or less known options and insights. The mitigation option biomass gets special attention in this study. The production of biomass has many (positive and negative) relations with other elements of the KfC program like space use and adaptation. Recently a global discussion on biomass usage for biofuels has started (food or fuel). Therefore a separate chapter will be dedicated to the sustainability aspects of biomass. An overview of technical mitigation measures with emphasis on the energy supply side is presented. This overview shows the large number of available and innovative options and the vast potential for reduction of the emissions of Greenhouse Gases (GHG) of these mitigation measures. The effectiveness of many mitigation options is strongly dependent on local conditions and implementation issues. A number of innovative mitigation measures such as aquatic biomass and biomass in combination with Carbon Capture and Storage (CCS) are described in more detail. Biomass for energy has many different forms and applications. It is one of the mitigation options with a high potential, but at the same time it can have negative environmental impacts and might compete with other forms of land use including food production. This makes bio-energy a promising but complex option, which makes careful evaluation necessary. Several examples of multifunctional land use show that by combining functions, synergy can be achieved. This could lead to a reduction of potentially negative impacts and thus easier implementation. Furthermore, novel technologies for reducing or offsetting climate change such as air capture and artificial cooling might have a high potential as mitigation option, but need to be examined before

  9. Assessing and Mitigating Hurricane Storm Surge Risk in a Changing Environment

    Hurricanes have induced devastating storm surge flooding worldwide. The impacts of these storms may worsen in the coming decades because of rapid coastal development coupled with sea-level rise and possibly increasing storm activity due to climate change. Major advances in coastal flood risk management are urgently needed. We present an integrated dynamic risk analysis for flooding task (iDraft) framework to assess and manage coastal flood risk at the city or regional scale, considering integrated dynamic effects of storm climatology change, sea-level rise, and coastal development. We apply the framework to New York City. First, we combine climate-model projected storm surge climatology and sea-level rise with engineering- and social/economic-model projected coastal exposure and vulnerability to estimate the flood damage risk for the city over the 21st century. We derive temporally-varying risk measures such as the annual expected damage as well as temporally-integrated measures such as the present value of future losses. We also examine the individual and joint contributions to the changing risk of the three dynamic factors (i.e., sea-level rise, storm change, and coastal development). Then, we perform probabilistic cost-benefit analysis for various coastal flood risk mitigation strategies for the city. Specifically, we evaluate previously proposed mitigation measures, including elevating houses on the floodplain and constructing flood barriers at the coast, by comparing their estimated cost and probability distribution of the benefit (i.e., present value of avoided future losses). We also propose new design strategies, including optimal design (e.g., optimal house elevation) and adaptive design (e.g., flood protection levels that are designed to be modified over time in a dynamic and uncertain environment).

  10. Financialization impedes climate change mitigation: Evidence from the early American solar industry

    Jerneck, Max

    2017-01-01

    The article investigates how financialization impedes climate change mitigation by examining its effects on the early history of one low-carbon industry, solar photovoltaics in the United States. The industry grew rapidly in the 1970s, as large financial conglomerates acquired independent firms. While providing needed financial support, conglomerates changed the focus from existing markets in consumer applications toward a future utility market that never materialized. Concentration of the industry also left it vulnerable to the corporate restructuring of the 1980s, when the conglomerates were dismantled and solar divisions were pared back or sold off to foreign firms. Both the move toward conglomeration, when corporations became managed as stock portfolios, and its subsequent reversal were the result of increased financial dominance over corporate governance. The American case is contrasted with the more successful case of Japan, where these changes to corporate governance did not occur. Insulated from shareholder pressure and financial turbulence, Japanese photovoltaics manufacturers continued to expand investment throughout the 1980s when their American rivals were cutting back. The study is informed by Joseph Schumpeter’s theory of creative destruction and Hyman Minsky’s theory of financialization, along with economic sociology. By highlighting the tenuous and conflicting relation between finance and production that shaped the early history of the photovoltaics industry, the article raises doubts about the prevailing approach to mitigate climate change through carbon pricing. Given the uncertainty of innovation and the ease of speculation, it will do little to spur low-carbon technology development without financial structures supporting patient capital. PMID:28435862

    Experts working on behalf of international development organisations need better tools to assist land managers in developing countries maintain their livelihoods, as climate change puts pressure on the ecosystem services that they depend upon. However, current understanding of livelihood vulnerability to climate change is based on a fractured and disparate set of theories and methods. This review therefore combines theoretical insights from sustainable livelihoods analysis with other analytical frameworks (including the ecosystem services framework, diffusion theory, social learning, adaptive management and transitions management) to assess the vulnerability of rural livelihoods to climate change. This integrated analytical framework helps diagnose vulnerability to climate change, whilst identifying and comparing adaptation options that could reduce vulnerability, following four broad steps: i) determine likely level of exposure to climate change, and how climate change might interact with existing stresses and other future drivers of change; ii) determine the sensitivity of stocks of capital assets and flows of ecosystem services to climate change; iii) identify factors influencing decisions to develop and/or adopt different adaptation strategies, based on innovation or the use/substitution of existing assets; and iv) identify and evaluate potential trade-offs between adaptation options. The paper concludes by identifying interdisciplinary research needs for assessing the vulnerability of livelihoods to climate change.

  12. Changing Climate, Challenging Choices: Identifying and Evaluating Climate Change Adaptation Options for Protected Areas Management in Ontario, Canada

    Lemieux, Christopher J.; Scott, Daniel J.

    2011-10-01

    Climate change will pose increasingly significant challenges to managers of parks and other forms of protected areas around the world. Over the past two decades, numerous scientific publications have identified potential adaptations, but their suitability from legal, policy, financial, internal capacity, and other management perspectives has not been evaluated for any protected area agency or organization. In this study, a panel of protected area experts applied a Policy Delphi methodology to identify and evaluate climate change adaptation options across the primary management areas of a protected area agency in Canada. The panel identified and evaluated one hundred and sixty five (165) adaptation options for their perceived desirability and feasibility. While the results revealed a high level of agreement with respect to the desirability of adaptation options and a moderate level of capacity pertaining to policy formulation and management direction, a perception of low capacity for implementation in most other program areas was identified. A separate panel of senior park agency decision-makers used a multiple criterion decision-facilitation matrix to further evaluate the institutional feasibility of the 56 most desirable adaptation options identified by the initial expert panel and to prioritize them for consideration in a climate change action plan. Critically, only two of the 56 adaptation options evaluated by senior decision-makers were deemed definitely implementable, due largely to fiscal and internal capacity limitations. These challenges are common to protected area agencies in developed countries and pervade those in developing countries, revealing that limited adaptive capacity represents a substantive barrier to biodiversity conservation and other protected area management objectives in an era of rapid climate change.

    Scenarios are used to explore the consequences of different adaptation and mitigation strategies under uncertainty. In this paper, two scenarios are used to explore developments with (1) no mitigation leading to an increase of global mean temperature of 4 °C by 2100 and (2) an ambitious mitigation

    Traditional concepts for ancillary benefit/co-benefit frameworks reflect a macro and welfare economics perspective. They are often designed to serve certain modelling requirements, and typically focus primarily on avoided environmental damages and/or on induced net employment. This paper presents a conceptual framework that is extended to non-environmental and non-climate-change externalities. It not only includes the net ancillary and co-benefits that accrue from the dynamics of technological innovation and market diffusion, but also those from spillover effects that arise from global trade, communications, and technology transfer, which can all have important impacts on both the business economics and the macroeconomic level. We show that multi-functionality of energy-efficient technologies at the useful energy level, in contrast to mono-functionality of energy conversion technologies, leads to net ancillary benefits/co-benefits of GHG mitigation that may go far beyond fossil energy savings and emission mitigation, and that are in many cases not (or at least not sufficiently) accounted for in investment decision-making and policy-making processes. Several illustrative examples are provided to underline the points that are made.

  15. Global climate change mitigation and sustainable forest management--The challenge of monitoring and verification

    Makundi, Willy R.

    1997-12-31

    In this paper, sustainable forest management is discussed within the historical and theoretical framework of the sustainable development debate. The various criteria and indicators for sustainable forest management put forth by different institutions are critically explored. Specific types of climate change mitigation policies/projects in the forest sector are identified and examined in the light of the general criteria for sustainable forest management. Areas of compatibility and contradiction between the climate mitigation objectives and the minimum criteria for sustainable forest management are identified and discussed. Emphasis is put on the problems of monitoring and verifying carbon benefits associated with such projects given their impacts on pre-existing policy objectives on sustainable forest management. The implications of such policy interactions on assignment of carbon credits from forest projects under Joint Implementation/Activities Implemented Jointly initiatives are discussed. The paper concludes that a comprehensive monitoring and verification regime must include an impact assessment on the criteria covered under other agreements such as the Biodiversity and/or Desertification Conventions. The actual carbon credit assigned to a specific project should at least take into account the negative impacts on the criteria for sustainable forest management. The value of the impacts and/or the procedure to evaluate them need to be established by interested parties such as the Councils of the respective Conventions.

  16. Climate change mitigation in developing countries through interregional collaboration by local governments: Japanese citizens' preference

    Nakamura, Hidenori; Kato, Takaaki

    2011-01-01

    This study explores the motivation of domestic and international interregional collaboration on climate change mitigation through carbon crediting by Japanese local governments, using a social survey. The study finds balanced collaboration with domestic partner regions and developing countries is preferred in the case of collaboration, given that the unit cost of collaboration is assumed lower than that of no collaboration. Appreciation of benefits such as technology transfer and local environmental improvement in developing countries increases the preference of collaboration with developing countries. Two factors hinder Japanese local governments' collaboration with developing countries from the perspective of citizens: a sense of environmental responsibility to reduce greenhouse gas (GHG) emissions within the city and a preference for domestic orientation even if the collaboration with developing countries is less costly and has benefits of technology transfer and local environmental improvement. The preference for a lower total cost of GHG emissions reductions is confirmed except for those with a sense of environmental responsibility. The study also finds that provision of information on mitigation projects and co-benefits would increase the preference for interregional collaboration with developing countries depending on the types of collaborative project, except for those with a sense of environmental responsibility. - Highlights: → We surveyed views of Japanese citizens on interregional/international cooperation of their cities for GHG reduction. → Sense of environmental responsibility is negatively correlated with the needs for cooperation. → Information on co-benefits of collaboration would strengthen preference for cooperation.

  17. Benefits of collaborative and comparative research on land use change and climate mitigation

    Zhu, Zhiliang; Gong, Peng

    The world's two largest economies are also the latest greenhouse gas emitters. The United States is committed to reduce the net greenhouse gas emission by 28% below the 2005 level by 2025. Similarly China also announced significant climate mitigation steps at the Paris climate convention. These policy plans will require actions including reduction of GHG emissions as well as protection of carbon stored in biologic pools and increase of carbon sequestration by the natural ecosystems. Major drivers of ecosystem carbon sequestration and protection of existing carbon resources include land use, disturbances, and climate change. Recent studies indicate that vegetated ecosystems in the United States remain as a carbon sink but the sink is weakening due to increased disturbances (such as wildfire and harvesting) and aging of forests. Unique land use policies in China such as large-scale afforestation in the recent decades have reportedly led to significant increase in total forest area and aboveground biomass, although it is not clear to what degree the increase has translated to strengthened net uptake of atmospheric CO2 and the rate of sequestration by vegetated ecosystems. What lessons can we draw from different land management and land use practices in the U.S. and China that can benefit scientific advances and climate mitigation goals? Research conducted collaboratively by the U.S. Geological Survey and China Ministry of Science and Technology has led to improved techniques for tracking and modeling land use change and ecosystem disturbances and improved understanding of consequences of different land use change and management practices on ecosystem carbon sequestration capacities.

    The increase of the anthropogenic carbon dioxide (CO2) affects the global carbon cycle altering the atmospheric system and initiates the climate changes. There are two ways to mitigate these changes, by maintaining the greenhouse gasses below the carbon budget and by conserving the marine and terrestrial vegetation for carbon sequestration. These two strategies become variable to the carbon sequestration index (CSI) that represents the potential of a region in carbon sequestration, according to its natural capacity. As a study case, we conducted carbon sequestration research in Bintan region (Bintan Island and its surrounding), Riau Archipelago province. This research was aimed to assess the CSI and its possibility for climate change mitigation. We observed carbon sequestration of seagrass meadows and mangrove, greenhouse gas (CO2) emission (correlated to population growth, the increase of vehicles), and CSI. Bintan region has 125,849.9 ha of vegetation area and 14,879.6 ha of terrestrial and marine vegetation area, respectively. Both vegetation areas are able to sequester 0.262 Tg C yr-1 in total and marine vegetation contributes about 77.1%. Total CO2 emission in Bintan region is up to 0.273 Tg C yr-1, produced by transportation, industry and land use sectors. Therefore, CSI of the Bintan region is 0.98, which is above the global average (i.e. 0.58). This value demonstrates that the degree of sequestration is comparable to the total carbon emission. This result suggests that Bintan’s vegetation has high potential for reducing greenhouse gas effects.

    Strategies to mitigate carbon dioxide emissions through forestry activities have been proposed, but ecosystem process-based integration of climate change, enhanced CO 2 , disturbance from fire, and management actions at regional scales are extremely limited. Here, we examine the relative merits of afforestation, reforestation, management changes, and harvest residue bioenergy use in the Pacific Northwest. This region represents some of the highest carbon density forests in the world, which can store carbon in trees for 800 y or more. Oregon's net ecosystem carbon balance (NECB) was equivalent to 72% of total emissions in 2011-2015. By 2100, simulations show increased net carbon uptake with little change in wildfires. Reforestation, afforestation, lengthened harvest cycles on private lands, and restricting harvest on public lands increase NECB 56% by 2100, with the latter two actions contributing the most. Resultant cobenefits included water availability and biodiversity, primarily from increased forest area, age, and species diversity. Converting 127,000 ha of irrigated grass crops to native forests could decrease irrigation demand by 233 billion m 3 ⋅y -1 Utilizing harvest residues for bioenergy production instead of leaving them in forests to decompose increased emissions in the short-term (50 y), reducing mitigation effectiveness. Increasing forest carbon on public lands reduced emissions compared with storage in wood products because the residence time is more than twice that of wood products. Hence, temperate forests with high carbon densities and lower vulnerability to mortality have substantial potential for reducing forest sector emissions. Our analysis framework provides a template for assessments in other temperate regions. Copyright © 2018 the Author(s). Published by PNAS.

  1. Global and local concerns: what attitudes and beliefs motivate farmers to mitigate and adapt to climate change?

    Haden, Van R; Niles, Meredith T; Lubell, Mark; Perlman, Joshua; Jackson, Louise E

    2012-01-01

    In response to agriculture's vulnerability and contribution to climate change, many governments are developing initiatives that promote the adoption of mitigation and adaptation practices among farmers. Since most climate policies affecting agriculture rely on voluntary efforts by individual farmers, success requires a sound understanding of the factors that motivate farmers to change practices. Recent evidence suggests that past experience with the effects of climate change and the psychological distance associated with people's concern for global and local impacts can influence environmental behavior. Here we surveyed farmers in a representative rural county in California's Central Valley to examine how their intention to adopt mitigation and adaptation practices is influenced by previous climate experiences and their global and local concerns about climate change. Perceived changes in water availability had significant effects on farmers' intention to adopt mitigation and adaptation strategies, which were mediated through global and local concerns respectively. This suggests that mitigation is largely motivated by psychologically distant concerns and beliefs about climate change, while adaptation is driven by psychologically proximate concerns for local impacts. This match between attitudes and behaviors according to the psychological distance at which they are cognitively construed indicates that policy and outreach initiatives may benefit by framing climate impacts and behavioral goals concordantly; either in a global context for mitigation or a local context for adaptation.

    Climate change is broadly recognized as a key environmental issue affecting social and ecological systems worldwide. At the Cancun summit of the United Nations Framework Convention on Climate Change's 16th Conference, the parties jointly agreed that the vulnerable groups particularly in developing countries and whose livelihood is based on land use practices are the most common victims as in most cases their activities are shaped by the climate. Therefore, solving the climate dilemma through mitigation processes and scientific research is an ethical concern. Thus combining the knowledge systems of the societies and scientific evidences can greatly assist in the creation of coping mechanisms for sustainable development in a situation of changing climate. International Humboldt Kolleg focusing on ''knowledge systems of societies and Climate Change'' was organized at ISEC. This event was of unique importance, as the year 2011-12 was celebrated as the 60th Anniversary of Diplomatic Relations between India and Germany with the motto ''Germany and India - Infinite Opportunities.'' This volume is the outcome of the papers presented during the IHK 2011 at ISEC, India. It reports on the present knowledge systems in a third world country which has always practiced a live and let live philosophy. Furthermore it provides valuable information for understanding the complexity of socio-ecological systems in relation to the projected impacts of climate change.

  4. Analysis of the economic impact of different Chinese climate policy options based on a CGE model incorporating endogenous technological change

    2009-01-01

    Abatement cost is the main concern for climate change mitigation and the key factor for mitigation cost is technological change. This study established an integrated economic, energy, environmental, dynamic, computable general equilibrium (CGE) model representing endogenous technological change for China's climate change policy analysis. This study analyzed and compared the economic impact of different approaches to mitigation commitments as well as the potential role of technological change in the formulation of mitigation targets and commitments, taking into account China's climate policy-making needs based on the current international climate negotiation process. The results show that, absolute emission limits similar to the Kyoto Protocol will seriously impede the future economic development of China, while the impact of an 80% reduction in carbon intensity, forecast for 2050 based on the 2005 level, is relatively small. Technological change can promote economic growth, improve energy efficiency and reduce carbon intensity per unit of output through the substitution of production factors. Consequently it can reduce marginal abatement cost and related GDP loss by mitigation. At the same time it can increase mitigation potentials and extend the emission reduction amount, showing that consideration of the impact of technological change when deciding the emission reduction targets is necessary.

  6. Impact of Real-world Factors Influencing Investment Decisions on the Costs and Distribution of Climate Change Mitigation

    Strategies to mitigate dangerous anthropogenic climate change require a dramatic transformation of the energy system to reduce greenhouse gas emissions, that in turn requires large-scale investments. Investment decisions depend not only on investment capital availability but also on investment risks. A number of factors such as national policy environments, quality of public and private institutions, sector, firm and technology specific characteristics can affect investors' assessments of risks, leading to a wide variation in the business climate for investment. Such heterogeneity in investment risks can have important implications, as investors usually respond to risks by requiring higher returns for riskier projects; delaying or forgoing the investments; or preferring to invest in existing, familiar projects. We study the impact of variation in investment risks on regional patterns of emissions mitigation, the cost of emissions mitigation and patterns of technology deployment. We modify an integrated assessment model, widely used in global climate policy analyses (the Global Change Assessment Model) and incorporate decisions on investments based on risks along two dimensions. Along the first dimension, we vary perceived risks associated with particular technologies. To do so, we assign a higher cost of capital for investment in low-carbon technologies as these involve intrinsically higher levels of regulatory and market risk. The second dimension uses a proxy to vary investment risks across regions, based on an institutional quality metric published by the World Economic Forum. Explicit representation of investment risks has two major effects. First, it raises the cost of emissions mitigation relative to a world with uniform investment risks. Second, it shifts the pattern of emissions mitigation, with industrialized countries mitigating more, and developing countries mitigating less. Our results suggest that institutional reforms aimed at lowering investment

    This article challenges the notion that energy efficiency and 'clean' energy technologies can deliver sufficient degrees of climate change mitigation. By six arguments not widely recognized in the climate policy arena, we argue that unrealistic technology optimism exists in current climate change mitigation assessments, and, consequently, world energy and climate policy. The overarching theme of the arguments is that incomplete knowledge of indirect effects, and neglect of interactions between parts of physical and social sub-systems, systematically leads to overly optimistic assessments. Society must likely seek deeper changes in social and economic structures to preserve the climatic conditions to which the human civilization is adapted. We call for priority to be given to research evaluating aspects of mitigation in a broad, system-wide perspective. - Highlights: > We highlight some of the simplifying assumptions in climate change mitigation scenarios. > Mitigation assessments are the basis of unfounded technology optimism in climate policy. > Society must likely seek deeper changes in social and economic structures to stabilize climate.

The overarching theme of the arguments is that incomplete knowledge of indirect effects, and neglect of interactions between parts of physical and social sub-systems, systematically leads to overly optimistic assessments. Society must likely seek deeper changes in social and economic structures to preserve the climatic conditions to which the human civilization is adapted. We call for priority to be given to research evaluating aspects of mitigation in a broad, system-wide perspective. - Highlights: → We highlight some of the simplifying assumptions in climate change mitigation scenarios. → Mitigation assessments are the basis of unfounded technology optimism in climate policy. → Society must likely seek deeper changes in social and economic structures to stabilize climate.

    Nutrient reduction measures have been already taken by wealthier countries to decrease nutrient loads to coastal waters, in most cases however, prior to having properly assessed their ecological effectiveness and their economic costs. In this paper we describe an original integrated impact assessment methodology to estimate the direct cost and the ecological performance of realistic nutrient reduction options to be applied in the Southern North Sea watershed to decrease eutrophication, visible as Phaeocystis blooms and foam deposits on the beaches. The mathematical tool couples the idealized biogeochemical GIS-based model of the river system (SENEQUE-RIVERSTRAHLER) implemented in the Eastern Channel/Southern North Sea watershed to the biogeochemical MIRO model describing Phaeocystis blooms in the marine domain. Model simulations explore how nutrient reduction options regarding diffuse and/or point sources in the watershed would affect the Phaeocystis colony spreading in the coastal area. The reference and prospective simulations are performed for the year 2000 characterized by mean meteorological conditions, and nutrient reduction scenarios include and compare upgrading of wastewater treatment plants and changes in agricultural practices including an idealized shift towards organic farming. A direct cost assessment is performed for each realistic nutrient reduction scenario. Further the reduction obtained for Phaeocystis blooms is assessed by comparison with ecological indicators (bloom magnitude and duration) and the cost for reducing foam events on the beaches is estimated. Uncertainty brought by the added effect of meteorological conditions (rainfall) on coastal eutrophication is discussed. It is concluded that the reduction obtained by implementing realistic environmental measures on the short-term is costly and insufficient to restore well-balanced nutrient conditions in the coastal area while the replacement of conventional agriculture by organic farming

  11. Climate change and cities: why urban agendas are central to adaptation and mitigation

    Reid, Hannah; Satterthwaite, David

    2007-12-15

    Cities could hold the key to slowing and eventually stopping global warming. Most greenhouse gas emissions are generated from producing the goods and services used by middle- and upper-income urban consumers. Keeping global warming within safe limits demands far more energy-efficient urban buildings and production systems and urban lifestyles that are far less carbon-intensive. It is up to high-income nations — the biggest contributors to greenhouse gas emissions past and present — to show how such a transformation can be combined with high living standards. However, urgent action is also needed in the urban areas of low- and middleincome countries, both through mitigation to curb greenhouse gas emissions, and adaptation to the serious risks that climate change brings.

  12. Enhancing international technology cooperation for climate change mitigation. Lessons from an electromobility case study

    Bhasin, Shikha

    2014-07-01

    As a global agreement on climate mitigation and absolute emissions reductions remains grid-locked, this paper assesses whether the prospects for international technology cooperation in low-carbon sectors can be improved. It analyses the case of international cooperation on electric vehicle technologies to elaborate on the trade-offs that cooperation such as this inherently attempts to balance- national growth objectives of industrial and technology development versus the global goods benefit of reducing greenhouse gas (GHG) emissions. It focuses on bilateral German-Chinese programmes for electric vehicle development, as well as multilateral platforms on low-carbon technology cooperation related to electric vehicles. Based on insights from these cases studies, this paper ultimately provides policy recommendations to address gaps in international technology cooperation at a bilateral level for ongoing German-Chinese engagement on electric vehicles; and at a multilateral level with a focus on the emerging technology cooperation framework of the United Nations Framework Convention on Climate Change (UNFCCC).

  16. Reforestation and Climate Change Mitigation. A background Study for Joint Implementation in China and Indonesia

    Gan, Lin; Naess, Lars Otto; Kasa, Sjur; O` Brien, Karen L

    1998-12-01

    This report studies the importance of institutional barriers in promoting reforestation as a means of mitigating global climate change. It is argued that cost-effective implementation of reforestation depends on proper institutional settings in host countries. Particular emphasis is placed on the role of property rights. The relationship between various stakeholders, such as governments, non-governmental organisations, the private sector, and international aid agencies is analysed. Discussed aspects include conflicts among stakeholders, long-term security or stability of property rights regimes, distribution of property rights, and information exchange. The forest situation in China and Indonesia is used as an example. The study outlines a number of conflicts in the property rights regime that need a better understanding. Some important issues that need further study are listed. 66 refs., 1 fig., 2 tabs.

  17. Combating the effects of climatic change on forests by mitigation strategies

    Dieter Matthias

    2010-11-01

    Full Text Available Abstract Background Forests occur across diverse biomes, each of which shows a specific composition of plant communities associated with the particular climate regimes. Predicted future climate change will have impacts on the vulnerability and productivity of forests; in some regions higher temperatures will extend the growing season and thus improve forest productivity, while changed annual precipitation patterns may show disadvantageous effects in areas, where water availability is restricted. While adaptation of forests to predicted future climate scenarios has been intensively studied, less attention was paid to mitigation strategies such as the introduction of tree species well adapted to changing environmental conditions. Results We simulated the development of managed forest ecosystems in Germany for the time period between 2000 and 2100 under different forest management regimes and climate change scenarios. The management regimes reflect different rotation periods, harvesting intensities and species selection for reforestations. The climate change scenarios were taken from the IPCC's Special Report on Emission Scenarios (SRES. We used the scenarios A1B (rapid and successful economic development and B1 (high level of environmental and social consciousness combined with a globally coherent approach to a more sustainable development. Our results indicate that the effects of different climate change scenarios on the future productivity and species composition of German forests are minor compared to the effects of forest management. Conclusions The inherent natural adaptive capacity of forest ecosystems to changing environmental conditions is limited by the long life time of trees. Planting of adapted species and forest management will reduce the impact of predicted future climate change on forests.

  18. Sectoral approaches establishment for climate change mitigation in Thailand upstream oil and gas industry

    Chaiyapa, Warathida; Esteban, Miguel; Kameyama, Yasuko

    2016-01-01

    Understanding the upstream oil and gas (O&G) industry's responses to climate change and what factors can be influential to trigger their mitigation strategies is crucial for policy-makers to harness the huge resources that this industry can mobilize towards environmental protection. Considering that individual climate change efforts are unlikely to affect global mitigation paths, the study investigates the possibility that sectoral approaches can help in the reduction of greenhouse gas emissions, using Thailand as a case study. It conducted online questionnaire surveys and semi-structured interviews to acquire primary data from companies and key informants from the government, NGOs, NPOs and academics. The results suggested that, among three possible groups of factors that could affect company decisions on whether to promote sectoral approaches, domestic politics (particularly the Thai government) is the most important, though other factors also play important and interrelated roles. The most welcomed type of scheme that could be envisaged would appear to be a sectoral agreement between government and industry. Finally, the authors provide two main policy recommendations, namely the establishment of an industrial association of O&G companies and for it to target how to start looking at measures to reduce greenhouse gas emissions amongst large companies in the sector. - Highlights: •Examining the possibility of establishing a sectoral approach Thailand's upstream O&G industry. •Analytical framework was constructed to ascertain most influential factors. •Questionnaires and interviews were employed with companies, government, NGOs and academic. •Domestic politics is the most determining factor, but other factors have strong interrelation. •Sectoral agreement between government and industry is the most likely scheme to be established.

  19. Exploring Opportunities for Promoting Synergies between Climate Change Adaptation and Mitigation in Forest Carbon Initiatives

    Eugene L. Chia

    2016-01-01

    Full Text Available There is growing interest in designing and implementing climate change mitigation and adaptation (M + A in synergy in the forest and land use sectors. However, there is limited knowledge on how the planning and promotion of synergies between M + A can be operationalized in the current efforts to mitigate climate change through forest carbon. This paper contributes to fill this knowledge gap by exploring ways of planning and promoting M + A synergy outcomes in forest carbon initiatives. It examines eight guidelines that are widely used in designing and implementing forest carbon initiatives. Four guiding principles with a number of criteria that are relevant for planning synergy outcomes in forest carbon activities are proposed. The guidelines for developing forest carbon initiatives need to demonstrate that (1 the health of forest ecosystems is maintained or enhanced; (2 the adaptive capacity of forest-dependent communities is ensured; (3 carbon and adaptation benefits are monitored and verified; and (4 adaptation outcomes are anticipated and planned in forest carbon initiatives. The forest carbon project development guidelines can encourage the integration of adaptation in forest carbon initiatives. However, their current efforts guiding projects and programs to deliver biodiversity and environmental benefits, ecosystem services, and socioeconomic benefits are not considered explicitly as efforts towards enhancing adaptation. An approach for incentivizing and motivating project developers, guideline setters, and offset buyers is imperative in order to enable existing guidelines to make clear contributions to adaptation goals. We highlight and discuss potential ways of incentivizing and motivating the explicit planning and promotion of adaptation outcomes in forest carbon initiatives.

    2014-06-01

    Full Text Available Seaweed is an important aquaculture commodity that could contribute on climate change mitigation, related to its ability on absorbing CO2, as one of the green house gases, through photosynthesis. This study aimed to analyze seaweed potencies on carbon sequestration in the context of climate change mitigation while still resulting optimum production as primary purpose and to analyze the carrying capacity of Gerupuk Bay in order to manage sustainability of seaweed aquaculture. Seaweed, (Kappaphycus alvarezii was cultivated with long-line system in Gerupuk Bay, West Nusa Tenggara, during five months for three cultivation cycles. Samplings were conducted at days-15, 30, and 45 with CO2 absorption rates as main parameters. Water carrying capacity was calculated to determine the ability of Gerupuk Bay waters for supporting development of sustainable seaweed aquaculture. The results showed that absorption rates of CO2 by seaweed (K. alvarezii were different at each sampling days of cultivation periods; the highest value was at 10-20 days of cultivation. CO2 absorption analysis resulted based on sampling days of cultivation period could be appl ied to formulate the strategies for management of sustainable seaweed aquaculture, with optimal production and positively contributed to the environment. However, waters carrying capacity should also be considered as major aspect in the application of seaweed cultivation management, thus it can run continuously without causing conflicts with other interests.

    Autism Spectrum Disorder (ASD) is characterized by impairments in social interaction, social communication, and repetitive and stereotyped behaviors. Recent work has begun to explore gene × environmental interactions in the etiology of ASD. We previously reported that prenatal stress exposure in stress-susceptible heterozygous serotonin transporter (SERT) KO pregnant dams in a mouse model resulted in autism-like behavior in the offspring (SERT/S mice). The association between prenatal stress and ASD appears to be affected by maternal SERT genotype in clinical populations as well. Using the mouse model, we examined autistic-like behaviors in greater detail, and additionally explored whether diet supplementation with docosahexaenoic acid (DHA) may mitigate the behavioral changes. Only male SERT/S mice showed social impairment and stereotyped behavior, and DHA supplementation ameliorated some of these behaviors. We also measured monoamine levels in the SERT/S mice after three treatment paradigms: DHA-rich diet continuously from breeding (DHA diet), DHA-rich diet only after weaning (CTL/DHA diet) and control diet only (CTL diet). The dopamine (DA) content in the striatum was significantly increased in the SERT/S mice compared with wild-type (WT) mice, whereas no difference was observed with noradrenaline and serotonin content. Moreover, DA content in the striatum was significantly reduced in the SERT/S mice with the DHA-rich diet provided continuously from breeding. The results indicate that autism-associated behaviors and changes in the dopaminergic system in this setting can be mitigated with DHA supplementation. Copyright © 2017 IBRO.

  2. Asia's role in mitigating climate change: A technology and sector specific analysis with ReMIND-R

    Luderer, Gunnar; Pietzcker, Robert C.; Kriegler, Elmar; Haller, Markus; Bauer, Nico

    2012-01-01

    We use the ReMIND-R model to analyze the role of Asia in the context of a global effort to mitigate climate change. We introduce a novel method of secondary energy based mitigation shares, which allows us to quantify the economic mitigation potential of technologies in different regions and final energy carriers. The 2005 share of Asia in global CO 2 emissions amounts to 38%, and is projected to grow to 53% under business-as-usual until the end of the century. Asia also holds a large fraction of the global mitigation potential. A broad portfolio of technologies is deployed in the climate policy scenarios. We find that biomass in combination with CCS, other renewables, and end-use efficiency each make up a large fraction of the global mitigation potential, followed by nuclear and fossil CCS. We find considerable differences in decarbonization patterns across the final energy types electricity, heat and transport fuels. Regional differences in technology use are a function of differences in resource endowments, and structural differences in energy end use. Under climate policy, a substantial mitigation potential of non-biomass renewables emerges for China and other developing countries of Asia (OAS). Asia also accounts for the dominant share of the global mitigation potential of nuclear energy. In view of the substantial near term investments into new energy infrastructure in China and India, early adoption of climate policy prevents lock-in into carbon intensive infrastructure and thus leads to a much higher long-term mitigation potential. - Highlights: ► We develop a novel methodology for the attribution of emission reductions to technologies. ► Asia accounts for a substantial and increasing share of global CO 2 emissions. ► A broad portfolio of technologies contributes to emission reductions. ► Early action increases the long term mitigation potential of China and India.

  3. Obesity and climate change mitigation in Australia: overview and analysis of policies with co-benefits.

    Lowe, Melanie

    2014-02-01

    To provide an overview of the shared structural causes of obesity and climate change, and analyse policies that could be implemented in Australia to both equitably reduce obesity rates and contribute to mitigating climate change. Informed by the political economy of health theoretical framework, a review was conducted of the literature on the shared causes of, and solutions to, obesity and climate change. Policies with potential co-benefits for climate change and obesity were then analysed based upon their feasibility and capacity to reduce greenhouse gas emissions and equitably reduce obesity rates in Australia. Policies with potential co-benefits fit within three broad categories: those to replace car use with low-emissions, active modes of transport; those to improve diets and reduce emissions from the food system; and macro-level economic policies to reduce the over-consumption of food and fossil fuel energy. Given the complex causes of both problems, it is argued that a full spectrum of complementary strategies across different sectors should be utilised. Such an approach would have significant public health, social and environmental benefits. © 2014 The Authors. ANZJPH © 2014 Public Health Association of Australia.

    In this study, 995 respondents in a representative sample of the Dutch general population are set in the situation of policymakers: they are faced with the issue of fulfilling the Dutch demand for energy in 2030 in such a way that emissions of carbon dioxide will be reduced by 50%. In the Information-Choice Questionnaire (ICQ) that was developed for this, respondents evaluated information from experts on seven options for CO2 emission reduction and their consequences. Two CCS options were compared to two energy efficiency options, a wind energy option, a biomass energy option, and a nuclear energy option. Results show that people are not that enthusiastic regarding the two CCS options. These are evaluated 5.3 and 5.9 on average on a scale of 1-10 and not often chosen as one of the three preferred options, but they are also rarely rejected. Most of the other options in the questionnaire were evaluated rather positively, except nuclear energy and the more ambitious efficiency option. Analysis shows that the evaluation of the information regarding consequences moderately influences how options are evaluated overall. The results further indicate that the CCS options are evaluated less positively due to the comparison with other options.

  6. The mitigation framework in the 2015 climate change agreement: from targets to pathways

    Spencer, Thomas; Colombier, Michel; Ribera, Teresa; Sha, Fu; Ji, Zou

    2014-01-01

    This paper is an effort between researchers from different countries and with different backgrounds to achieve an agreed text on an important issue in the climate negotiations through a thought experiment of 'think tank level negotiation'. It is a significant achievement for two groups of authors from China and Europe to have come this far. Countries have agreed to negotiate a new climate agreement by 2015. One of the key elements of this negotiation process will be a new mitigation framework and new emissions targets for all. How should the information that Parties put forward be structured, in order to promote participation, equity, transparency and ambition? The new agreement needs to find a way to allow the continuous strengthening of the action of sovereign states, to reflect the 2 deg. C objective. It will also need to provide a flexible and equitable framework for mitigation targets, to reflect both different levels of uncertainty and the large spectrum of countries and gaps in the development of different country groups. There is a need to shift out of the 'target mentality' and towards an understanding of climate change as the challenge of shifting long-term social, technological, investment and infra-structural pathways, as well as behaviours. Uncertainties in such structural processes may be particularly high in developing or emerging countries still undergoing industrialization, demographic shift, and urbanization. Mastering them requires long-term policy horizons, cooperation, technology innovation and policy learning, focusing on the drivers of emissions reductions. The Warsaw decision stated in 2013 that mitigation targets would be nationally-determined. In this context, the discussion around a global goal should no longer be seen as a basis for top-down allocation, but rather as a directional reference against which global progress must be assessed to identify the gap to be filled to foster enhanced action. It is essential to

  7. Applications of Advanced Technology for Monitoring Forest Carbon to Support Climate Change Mitigation

    Measurement, Reporting, and Verification (MRV) is a broad concept guiding the application of monitoring technology to the needs of countries or entities for reporting and verifying reductions in greenhouse gas emissions or increases in greenhouse gas sinks. Credibility, cost-effectiveness, and compatibility are important features of global MRV efforts that can support implementation of climate change mitigation programs such as Reducing Emissions from Deforestation and Forest Degradation and Sustainable Forest Management (REDD+). Applications of MRV technology may be tailored to individual country circumstances following guidance provided by the Intergovernmental Panel on Climate Change; hence, there is no single approach that is uniquely viable but rather a range of ways to integrate new MRV methods. MRV technology is advancing rapidly with new remote sensing and advanced measurement of atmospheric CO2, and in situ terrestrial and ocean measurements, coupled with improvements in data analysis, modeling, and assessing uncertainty. Here we briefly summarize some of the most application-ready MRV technologies being developed under NASA's Carbon Monitoring System (CMS) program, and illustrate how these technologies may be applied for monitoring forests using several case studies that span a range of scales, country circumstances, and stakeholder reporting requirements. We also include remarks about the potential role of advanced monitoring technology in the context of the global climate accord that is expected to result from the 21st session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, which is expected to take place in December 2015, in Paris, France.

  8. Perpetual American vanilla option pricing under single regime change risk: an exhaustive study

    Montero, Miquel

    2009-07-01

    Perpetual American options are financial instruments that can be readily exercised and do not mature. In this paper we study in detail the problem of pricing this kind of derivatives, for the most popular flavour, within a framework in which some of the properties—volatility and dividend policy—of the underlying stock can change at a random instant of time but in such a way that we can forecast their final values. Under this assumption we can model actual market conditions because most relevant facts usually entail sharp predictable consequences. The effect of this potential risk on perpetual American vanilla options is remarkable: the very equation that will determine the fair price depends on the solution to be found. Sound results are found under the optics both of finance and physics. In particular, a parallelism among the overall outcome of this problem and a phase transition is established.

  9. Impact of population growth and population ethics on climate change mitigation policy.

    2017-11-14

    Future population growth is uncertain and matters for climate policy: higher growth entails more emissions and means more people will be vulnerable to climate-related impacts. We show that how future population is valued importantly determines mitigation decisions. Using the Dynamic Integrated Climate-Economy model, we explore two approaches to valuing population: a discounted version of total utilitarianism (TU), which considers total wellbeing and is standard in social cost of carbon dioxide (SCC) models, and of average utilitarianism (AU), which ignores population size and sums only each time period's discounted average wellbeing. Under both approaches, as population increases the SCC increases, but optimal peak temperature decreases. The effect is larger under TU, because it responds to the fact that a larger population means climate change hurts more people: for example, in 2025, assuming the United Nations (UN)-high rather than UN-low population scenario entails an increase in the SCC of 85% under TU vs. 5% under AU. The difference in the SCC between the two population scenarios under TU is comparable to commonly debated decisions regarding time discounting. Additionally, we estimate the avoided mitigation costs implied by plausible reductions in population growth, finding that large near-term savings ($billions annually) occur under TU; savings under AU emerge in the more distant future. These savings are larger than spending shortfalls for human development policies that may lower fertility. Finally, we show that whether lowering population growth entails overall improvements in wellbeing-rather than merely cost savings-again depends on the ethical approach to valuing population.

  10. Greenhouse gas emission mitigation relevant to changes in municipal solid waste management system.

    Pikoń, Krzysztof; Gaska, Krzysztof

    2010-07-01

    Standard methods for assessing the environmental impact of waste management systems are needed to underpin the development and implementation of sustainable waste management practice. Life cycle assessment (LCA) is a tool for comprehensively ensuring such assessment and covers all impacts associated with waste management. LCA is often called "from cradle to grave" analysis. This paper integrates information on the greenhouse gas (GHG) implications of various management options for some of the most common materials in municipal solid waste (MSW). Different waste treatment options for MSW were studied in a system analysis. Different combinations of recycling (cardboard, plastics, glass, metals), biological treatment (composting), and incineration as well as land-filling were studied. The index of environmental burden in the global warming impact category was calculated. The calculations are based on LCA methodology. All emissions taking place in the whole life cycle system were taken into account. The analysis included "own emissions," or emissions from the system at all stages of the life cycle, and "linked emissions," or emissions from other sources linked with the system in an indirect way. Avoided emissions caused by recycling and energy recovery were included in the analysis. Displaced emissions of GHGs originate from the substitution of energy or materials derived from waste for alternative sources. The complex analysis of the environmental impact of municipal waste management systems before and after application of changes in MSW systems according to European Union regulations is presented in this paper. The evaluation is made for MSW systems in Poland.

  11. Will Transition of Staple Food Strategy in China Really Mitigate Global Climate Change?

    Liu, B.; Zhao, D.

    2017-12-01

    With the increase in agricultural demand, reducing greenhouse gas (GHG) emissions is a vital challenge in mitigating climate change. Potato staple food strategy in China introduced by Ministry of Agriculture in 2015 is to gradually adjust staple food structure, which provides an opportunity to meet with the challenge. Apart from staple food structure, difference on energy, material input, geography, and crop management are essential to determine agriculture's contribution to climate change. In this study, we conduct a life cycle analysis of four staple foods in China, namely rice, wheat, maize, and potato, to develop crop-specific estimates of GHG emissions and GHG intensity by using `Production intensity' (carbon dioxide equivalent emissions per kilocalorie produced), to help us understand potential synergies and frictions between food producing and climate mitigation. Data used in this study is on city / province levels if city level is unavailable in 2015. First, we evaluate GHG reductions due to transition of staple food structure in China. Staple food GHG emissions in China are 546.90 Tg CO2e yr-1 in 2015, with 47.6%, 21.9%, 27.3% and 3.2% from rice, wheat, maize and potato. Mean production intensity of staple food is 0.45 Mg CO2e M kcal-1 in 2015. Maize leads the intensity with 0.77 Mg CO2e M kcal-1, followed by rice (0.49 Mg CO2e M kcal-1), wheat (0.28 Mg CO2e M kcal-1) and potato (0.24 Mg CO2e M kcal-1). After staple food structure adjustment, 25 Tg CO2e yr-1 (4.2%) reduction will be accomplished in 2020 without any crop management improvement. Further reduction (33.3% - 40.4%) could be achieved with crop management improvement. In addition, because of staple food structure switching, native rice production will decline, which might lead to more export from countries with higher production intensity. Estimated emission leakage from rice import is 30.10 Tg CO2e yr-1, exceeds emission reduction in native China. Therefore, potato staple food strategy could

  12. Soils as a Solution: The Potential of Rangelands to Contribute to Climate Change Mitigation

    Silver, W. L.; Ryals, R.; DeLonge, M. S.; Owen, J. J.

    2015-12-01

    The majority of soil-related climate change research has focused on describing the problem - estimating rates of carbon (C) losses and greenhouse gas (GHG) emissions from natural and managed ecosystems. More research is needed to explore potential solutions to climate change through mitigation and adaptation. Here we report on an integrated set of studies aimed at critically evaluating the biogeochemical potential of rangeland soils to help mitigate climate change, while improving the sustainability and productivity of food production systems. We explored direct effects through enhanced net primary production (NPP) and soil C sequestration, and indirect effects through diversion of high emitting sources to lower emitting organic matter dynamics. We used a combination of long- and short-term field experiments, modeling, laboratory assays, life cycle assessment (LCA), and meta-analyses in consultation with a diverse group of stakeholders from both the private and public sectors. We found that organic matter amendments held particularly strong potential. Compost amendments increased soil C storage by 0.5-1.0 Mg C ha-1 y-1 in surface soils over 5 y, and increased NPP and water holding capacity. We measured 1.0 Mg of new C ha-1 y-1 over 3 y. Long-term amendment of cattle manure increased surface soil C by 19.0±7.3 Mg C ha-1 relative to unmanured fields. However, field and modeling experiments suggested that manure amendments lead to large nitrous oxide emissions that eventually eliminated CO2e benefits, whereas compost amendments continued to benefit climate for decades longer. An LCA identified a broader range of climate impacts. When scaled to an area of 25% of California's rangelands, new C sequestered following compost amendments (21 million Mg CO2e) exceeded emissions from cattle (15 million Mg CO2e); diverting organics from waste streams to amendments led to additional GHG savings. In collaboration with our partners, our research contributed to the development of

  13. Integrated assessment of global water scarcity over the 21st century - Part 2: Climate change mitigation policies

    We investigate the effects of emission mitigation policies on water scarcity both globally and regionally using the Global Change Assessment Model (GCAM), a leading community integrated assessment model of energy, agriculture, climate, and water. Three climate policy scenarios with increasing mitigation stringency of 7.7, 5.5, and 4.2 W m-2 in year 2095 (equivalent to the SRES A2, B2, and B1 emission scenarios, respectively), under two carbon tax regimes (a universal carbon tax (UCT) which includes land use change emissions, and a fossil fuel and industrial emissions carbon tax (FFICT) which excludes land use change emissions) are analyzed. The results are compared to a baseline scenario (i.e. no climate change mitigation policy) with radiative forcing reaching 8.8 W m-2 (equivalent to the SRES A1Fi emission scenario) by 2095. When compared to the baseline scenario and maintaining the same baseline socioeconomic assumptions, water scarcity declines under a UCT mitigation policy but increases with a FFICT mitigation scenario by the year 2095 particularly with more stringent climate mitigation targets. The decreasing trend with UCT policy stringency is due to substitution from more water-intensive to less water-intensive choices in food and energy production, and in land use. Under the FFICT scenario, water scarcity is projected to increase driven by higher water demands for bio-energy crops. This study implies an increasingly prominent role for water availability in future human decisions, and highlights the importance of including water in integrated assessment of global change. Future research will be directed at incorporating water shortage feedbacks in GCAM to better understand how such stresses will propagate across the various human and natural systems in GCAM.

  14. Biochar as a Strategy for Sustainable Land Management, Poverty Reduction and Climate Change Mitigation/Adaptation? Thermolysis of lignin for value-added products

    Rodriguez Tejerina, V.M.

    2010-08-15

    In the context of current concerns about food security, energy security and environmental degradation, the characteristics of biochar are analyzed to determine if biochar systems are a possible solution to these interlinked global issues. With this purpose, the mechanisms by which biochar can affect global biogeochemical cycles are revised. Feasibility of biochar production and application to soil, among other options, is then examined under the criteria of energy, greenhouse gas emissions and financial performance. This is carried out by using life-cycle assessments (LCA) from the literature and by performing a cost-benefit analysis, in the context of a developing country. It is determined that, under certain conditions detailed in the body of the work, biochar can be well suited as a strategy for promoting sustainable land management, climate change mitigation and adaptation, and subsequently, poverty reduction. Among the relevant variables that determine the feasibility of biochar systems are: feedstock; production conditions; geographic context; and current management of biomass.

  15. Forest policy implications of climate change: Economic impacts and potential mitigation strategies

    Hodges, D.G.; Belli, K.L.; Watson, W.F.; Regens, J.L.

    1994-01-01

    Increasing mean global temperatures due to rising levels of carbon dioxide and other ''greenhouse'' gases in the atmosphere could affect the distribution of commercially important forests in North America significantly. The temperature increases might outpace the ability of forests to adapt, causing considerable stress and mortality to trees in the southern part of their range without a commensurate increase in growth across the expanding range. If realized, these potential biological impacts on forest distribution and health would affect management decisions substantially and could adversely impact forest-based economies in the United States. Specific effects on forest management include changes in the methods and costs of fire, insect, and disease protection; greater demands on forest lands for conversion to food production; and uncertain changes in site quality. One means of mitigating the effects of CO 2 emissions is to establish tree plantations for carbon sequestration. Preliminary analyses suggest that a program aimed at marginal cropland in the South could store more than 563 million tons of carbon over 45 years, although 90 million tons would be lost due to risks associated with plantations

  16. US/Japan workshop on mitigation and adaptation technologies related to global climate change

    Bernthal, F.M.

    1993-12-31

    It is a great pleasure for me to have the honor of delivering the keynote address for this important gathering, an honor enhanced further because of the many activities and historic relationships represented by this workshop. First of all, it represents the spirit of continuing cooperation and good relations between the United States and Japan. With the aid of the framework provided by the U.S./Japan Science and Technology Agreement, our two nations can come together to address a problem that has no national boundaries {hor_ellipsis} and we can think about solutions of potential benefit to all citizens of the global community. This workshop also symbolizes the spirit of cooperation so characteristic of the conduct of research in science and technology -- cooperation between us as individual scientists and engineers, between the various institutions we represent, and across our diverse disciplines. This workshop is only the second of its kind. The first US/Japan Workshop on global climate change was held last year in Japan. That workshop focused on cooperative scientific research in the United States and Japan. Out of it came a general agreement to continue collaborative work and to extend cooperation into the area of global change-related technologies, in particular those technologies that hold promise for mitigation and adaptation.

  17. Voluntary business activities to mitigate climate change: Case studies in Japan

    Wakabayashi, Masayo

    2013-01-01

    Voluntary business activities, such as the voluntary action plans conducted by comprehensive business associations in Japan to reduce environmental damage, are viable policy instruments alongside regulations and economic incentives (e.g. taxes and emissions trading schemes). This paper examines three case studies in which voluntary activities have played a successful role in mitigating climate change. Based on interviews with business organisations together with a literature review and data analysis, we show why businesses are motivated to take socially responsible actions and describe the major benefits of such activities. One of the important benefits of voluntary activities is their flexibility in phasing measures. This flexibility is greatly appreciated, since industries are able to retain control of their responses to future uncertainties, which allows them to tackle climate change issues aggressively. We conclude that voluntary activities have been more environmentally effective than alternative policy measures under a proper institutional framework, which consists of effective motivation mechanisms for businesses, governmental measures to encourage their compliance, and capable industrial associations that can lessen the transaction costs both of the government and of industry. - Highlights: • Businesses are well motivated to take suitable, technologically feasible actions. • Capability of industrial associations is a key to successful voluntary activities. • Flexibility allows businesses to manage uncertainty and aim for ambitious goals

  18. Implications of electric power sector restructuring on climate change mitigation in Argentina

    Hasson, G; Bouille, D [Instituto de Economia Energetica, (Argentina); Redlinger, R [UNEP, (Denmark)

    2000-05-01

    The Argentine electricity industry has undergone fundamental reforms since 1992, involving large-scale privatisation, and competition in generation and wholesale power markets. In terms of climate change mitigation, these reforms have had the beneficial effect of encouraging improved generation efficiency among thermal power plants and improved end-use consumption efficiency among large industrial firms. However, the reforms have also had the negative effect (from a climate change perspective) of encouraging an ever-increasing use of natural gas combustion for electricity generation, greatly diminishing the role of hydroelectric power which had previously played an important role in the Agentine electricity sector. This report examines the current structure and regulations of the Argentine electricity system and analyses the forces at work which are influencing current technology choices, both in terms of power generation and end-use consumption. The report goes on to examine international experiences in promoting renewable energy and energy efficiency technologies; and finally, the report considers the applicability of these various policy mechanisms within the Agentine context.

  19. Evaluation of forestry strategies for climate change mitigation in continental France. Scientific literature and main actors' positioning review

    Buitrago Esquinas, Miriam

    2012-01-01

    This work contributes to the current scientific debate regarding the optimization of the forest sector's contribution to mitigating climate change. A scientific literature review has pointed out some uncertainties on the contribution to emission reduction objectives in the short to medium-term of an increasing harvest of forest resources for wood construction and energy generation. Timing of mitigation benefits for a managed forest depends on forestry upstream characteristics(forest and soil type and silviculture method) and downstream characteristics (transport distance, use of wood, efficiency of wood based energy production, fossil-fuel based reference system that is substituted,etc). A survey conducted among national forest experts points out debates concerning optimal silviculture practices to mitigating climate change. These discussions are due to the trades-off between sequestering carbon in forest ecosystems and climatic benefits obtained by sustainable forest harvesting and use of wood products to displace fossil emissions.

  1. Public Perception of Climate Change and Mitigation Technologies; Percepcion Publica del Cambio Climatico y las Tecnologias de Mitigacion

    Sola, R; Sala, R; Oltra, C

    2007-09-27

    Public perception and understanding of climate change and mitigation policies may have a significant influence on the development of political programs as well as on individual behavioral intentions to address climate change. The study of public attitudes and beliefs about climate change and energy policy may be useful in the design of suitable communication strategies and in the efficient implementation of climate change mitigation and adaptation strategies. Based on a survey to the Spanish population, we analyze different issues such as the level of concern towards climate change, the existing knowledge about the contribution of different energy technologies to global warming, the attitudes toward energy technologies and the beliefs about potential adaptation strategies. Comparisons with other countries based on similar public opinion surveys are established to obtain a broader view of policy preferences and attitudes regarding climate change. (Author) 5 refs.

  2. Minimizing the cost of keeping options open for conservation in a changing climate.

    Policy documents advocate that managers should keep their options open while planning to protect coastal ecosystems from climate-change impacts. However, the actual costs and benefits of maintaining flexibility remain largely unexplored, and alternative approaches for decision making under uncertainty may lead to better joint outcomes for conservation and other societal goals. For example, keeping options open for coastal ecosystems incurs opportunity costs for developers. We devised a decision framework that integrates these costs and benefits with probabilistic forecasts for the extent of sea-level rise to find a balance between coastal ecosystem protection and moderate coastal development. Here, we suggest that instead of keeping their options open managers should incorporate uncertain sea-level rise predictions into a decision-making framework that evaluates the benefits and costs of conservation and development. In our example, based on plausible scenarios for sea-level rise and assuming a risk-neutral decision maker, we found that substantial development could be accommodated with negligible loss of environmental assets. Characterization of the Pareto efficiency of conservation and development outcomes provides valuable insight into the intensity of trade-offs between development and conservation. However, additional work is required to improve understanding of the consequences of alternative spatial plans and the value judgments and risk preferences of decision makers and stakeholders. © 2014 Society for Conservation Biology.

  3. Nitrogen use efficiency in the US economy: Towards mitigation of climate change impacts

    Nitrogen (N) interacts strongly with climate change in determining the severity and extent of many human health and environmental issues, such as eutrophication, poor air quality, and the maintenance of a secure food system. We were motivated by such N-climate interactions and their environmental impacts as part of a broader assessment of N in the continental United States. We here seek to identify and quantify inefficiencies associated with intentional N creation (i.e., creating synthetic N fertilizers and cultivating N-fixing legumes) among the major N-dependent sectors of the United States economy. We define efficiency of N use as the proportion N directly incorporated into food, fiber, biofuel, and industrial goods from the pool of intentionally created N. We are interested in whether reductions in N use could be achieved without changing the current functioning of the major N-dependent economic sectors. Our analysis points to substantial inefficiencies in N use at the national scale. A large percentage of the N applied as synthetic fertilizer and fixed by legumes annually fails to enter the United States food supply. Much of the unincorporated N enters air, land and water, where it can impact human health and ecosystems. The climate change forcing of N is uncertain, though it appears that the combined effects of intentionally and unintentionally created N on climate is roughly neutral in the United States (i.e., net effect of N-enhanced C storage, nitrous oxide emissions, N-based aerosols, and tropospheric ozone on climate forcing). Thus, it is reasonable to expect that improved efficiencies in N use would have minimal negative side effects on the United States economy, human health and the environment. We suggest that policies aimed at improving N-use efficiencies are an alternative to direct climate mitigation strategies in offsetting several impacts of climate change on human health and ecosystem functioning.

  4. Land use change and landslide characteristics analysis for community-based disaster mitigation.

    Chen, Chien-Yuan; Huang, Wen-Lin

    2013-05-01

    On August 8, 2009, Typhoon Morakot brought heavy rain to Taiwan, causing numerous landslides and debris flows in the Taihe village area of Meishan Township, Chiayi County, in south-central Taiwan. In the Taihe land is primary used for agriculture and land use management may be a factor in the area's landslides. This study explores Typhoon Morakot-induced landslides and land use changes between 1999 and 2009 using GIS with the aid of field investigation. Spot 5 satellite images with a resolution of 2.5 m are used for landslide interpretation and manually digitalized in GIS. A statistical analysis for landslide frequency-area distribution was used to identify the landslide characteristics associated with different types of land use. There were 243 landslides with a total area of 2.75 km(2) in the study area. The area is located in intrinsically fragile combinations of sandstone and shale. Typhoon Morakot-induced landslides show a power-law distribution in the study area. Landslides were mainly located in steep slope areas containing natural forest and in areas planted with bamboo, tea, and betel nut. Land covered with natural forest shows the highest landslide ratio, followed by bamboo, betel nut, and tea. Landslides thus show a higher ratio in areas planted with shallow root vegetation such as bamboo, betel nut, and tea. Furthermore, the degree of basin development is proportional to the landslide ratio. The results show that a change in vegetation cover results in a modified landslide area and frequency and changed land use areas have higher landslide ratios than non-changed. Land use management and community-based disaster prevention are needed in mountainous areas of Taiwan for hazard mitigation.

    decisions, the operation of the upstream reservoir (Como Lake) is optimised with respect to the real irrigation demand of the crops. Then, the farmers can re-adapt their decisions according with the new optimal operating strategy, thus activating a loop between the two systems that exchange expected supply and irrigation demand. Results show that the proposed interaction between farmers and water managers is able to enhance the efficiency of water management practices, foster crop production and mitigate climate change impacts.

  7. Continuity and Change: Dealing with Political Volatility to Advance Climate Change Mitigation Strategies—Examples from the Transport Sector

    Oliver Lah

    2017-06-01

    Full Text Available As the recent withdrawal of the United States from the Paris Agreement has shown, political volatility directly affects climate change mitigation policies, in particular in sectors, such as transport associated with long-term investments by individuals (vehicles and by local and national governments (urban form and transport infrastructure and services. There is a large potential for cost-effective solutions to reduce greenhouse gas emissions and to improve the sustainability of the transport sector that is yet unexploited. Considering the cost-effectiveness and the potential for co-benefits, it is hard to understand why efficiency gains and CO2 emission reductions in the transport sector are still lagging behind this potential. Particularly interesting is the fact that there is substantial difference among countries with relatively similar economic performances in the development of their transport CO2 emissions over the past thirty years despite the fact that these countries had relatively similar access to efficient technologies and vehicles. This study aims to explore some well-established political science theories on the particular example of climate change mitigation in the transport sector in order to identify some of the factors that could help explain the variations in success of policies and strategies in this sector. The analysis suggests that institutional arrangements that contribute to consensus building in the political process provide a high level of political and policy stability which is vital to long-term changes in energy end-use sectors that rely on long-term investments. However, there is no direct correlation between institutional structures, e.g., corporatism and success in reducing greenhouse gas emissions in the transport sector. Environmental objectives need to be built into the consensus-based policy structure before actual policy progress can be observed. This usually takes longer in consensus democracies than in

  8. Potential for Climate Change Mitigation in Degraded Forests: A Study from La Primavera, México

    Arturo Balderas Torres

    2013-11-01

    Full Text Available Forests contribute to climate change mitigation by removing atmospheric carbon dioxide and storing it in biomass and other carbon pools. Additionally, since appropriate forest management can reduce emissions from deforestation and forest degradation, it is important to estimate the magnitude of these services to include them into climate policy. We used a forest inventory stratified by canopy cover in the oak-pine forest of La Primavera Biosphere Reserve in México (30,500 ha, to assess the potential provision of forest carbon services. Inventory results were used in combination with a Landsat image to estimate carbon stocks in arboreal biomass. Potential carbon removals were calculated from published allometric equations and models estimating tree growth rates, for enhancements in forested areas and for reforestation/afforestation. Carbon stocks estimated in arboreal biomass at the time of the inventory were 4.16 MtCO2eq (3.42–4.89. The potential for further carbon sequestration and enhancement could take the level of stocks up to 9.77 MtCO2eq (7.66–11.89, 95% confidence interval; previous fires have degraded carbon stocks below their natural potential. The results present a gradient of carbon stocks for different degradation levels and are consistent with national and international estimates and previous local research. The baseline for the estimation of reduced emissions is critical for assessing the overall contribution of forests to mitigate climate change. The local baseline of emissions might be around 1% according to historical data; however, when enhancements and reduced emissions are valuated together, a baseline of 3.7% is required to prevent the creation of perverse incentives favouring previously degraded areas; considering these figures for reduced emissions, the yearly carbon services provided by La Primavera, including enhancements, sequestration and reduced emissions, could be between 169.4 ktCO2eq/year (134.8–204.5 and

  9. Crop-Cattle Integrated Farming System: An Alternative of Climatic Change Mitigation

    Munandar

    2015-08-01

    Full Text Available An integrated farming system is one of the alternatives for climatic change mitigation. This paper reports the application of corn-cattle based integrated farming system in Agrotechno Park Center of Palembang, and discusses its impact on CO2 fixation and the reduction of methane emissions. The study was based on the data of the first 6 yr from 2003 until 2009. The CO2 fixed in the soil and plants was determined based on the content of organic C which was multiplied by the index of 3.67. The methane gas produced by Balinese cattle and its dung was observed and modified into feed rations. The results showed that soil organic C increased from 40.80 tons C/ha in the 1st yr to 66.40 tons C/ha in the 6th yr. In addition, there was organic C fixation equivalent to 93.95 tons of CO2e. Corn biomass increased from 6.67 tons/ha to 18.66 tons/ha, equivalent to an increase in the fixation of atmospheric CO2e as much as 19.80 tons CO2e/ha. The supplementation of 60%-80% grass fodder with concentrate lowered the concentration of methane gas in cattle breathing by 28.7%, from 617 ppm to 440 ppm, while the methane emissions from cattle manure decreased by 31%, from 1367 mL/head/d to 943 mL/head/d. Installing a bio digester that generates biogas served to accommodate methane gas emissions from cattle dung and used it for bioenergy. Composting reduced the formation of methane gas from cattle manure through a regular process of turning over that gives aeration and forms aerobic condition in the heap of cattle dung. Recycling produces a variety of organic products that store carbon for a longer period of time and slowed the conversion of organic C into CO2. This study showed that the diverse activities of an integrated crop-cattle farming could be an alternative solution to climatic change mitigation.

  10. Climate change and prairie pothole wetlands: mitigating water-level and hydroperiod effects through upland management

    Renton, David A.; Mushet, David M.; DeKeyser, Edward S.

    2015-01-01

    Prairie pothole wetlands offer crucial habitat for North America’s waterfowl populations. The wetlands also support an abundance of other species and provide ecological services valued by society. The hydrology of prairie pothole wetlands is dependent on atmospheric interactions. Therefore, changes to the region’s climate can have profound effects on wetland hydrology. The relevant literature related to climate change and upland management effects on prairie pothole wetland water levels and hydroperiods was reviewed. Climate change is widely expected to affect water levels and hydroperiods of prairie pothole wetlands, as well as the biota and ecological services that the wetlands support. In general, hydrologic model projections that incorporate future climate change scenarios forecast lower water levels in prairie pothole wetlands and longer periods spent in a dry condition, despite potential increases in precipitation. However, the extreme natural variability in climate and hydrology of prairie pothole wetlands necessitates caution when interpreting model results. Recent changes in weather patterns throughout much of the Prairie Pothole Region have been in increased precipitation that results in increased water inputs to wetlands above losses associated with warmer temperatures. However, observed precipitation increases are within the range of natural climate variability and therefore, may not persist. Identifying management techniques with the potential to affect water inputs to prairie pothole wetlands would provide increased options for managers when dealing with the uncertainties associated with a changing climate. Several grassland management techniques (for example, grazing and burning) have the potential to affect water levels and hydroperiods of prairie pothole by affecting infiltration, evapotranspiration, and snow deposition.

  11. Technical backgrounder to CAPP input on June 14, 2002 workshop on federal climate change policy options

    2002-06-01

    This paper presents arguments regarding the Federal Discussion Paper on Climate Change which presents four options for Canada to implement the Kyoto Protocol. This paper describes some major flaws with the package. The Canadian Association of Petroleum Producers (CAPP) believes that policy on climate change should ensure that measures for the trade exposed industry sectors are based on achievable objectives and that all levels of government should take a coordinated approach to greenhouse gases. In addition there should be no unfair burden on any region or unfairness in any sector. Climate change policy objectives should also consider economic, environmental and social objectives. With respect to the Kyoto Protocol in particular, governments should assess the liability that ratification would create and determine whether it makes economic sense. CAPP argues that none of the four options in the federal discussion paper meets requirements for industry objectives and form of policies. In addition, if Canada does not shift industry and emissions to other countries, or buy foreign credits, energy use by consumers would have to be significantly reduced in order to meet the Kyoto target. It was also noted that if the 'polluter pay' policy proposal is to be adopted, it must be based on a thorough understanding of what it implies and be applied in such a way to reflect the reality of international markets

  12. Water resources planning under climate change: Assessing the robustness of real options for the Blue Nile

    Jeuland, Marc; Whittington, Dale

    2014-03-01

    This article presents a methodology for planning new water resources infrastructure investments and operating strategies in a world of climate change uncertainty. It combines a real options (e.g., options to defer, expand, contract, abandon, switch use, or otherwise alter a capital investment) approach with principles drawn from robust decision-making (RDM). RDM comprises a class of methods that are used to identify investment strategies that perform relatively well, compared to the alternatives, across a wide range of plausible future scenarios. Our proposed framework relies on a simulation model that includes linkages between climate change and system hydrology, combined with sensitivity analyses that explore how economic outcomes of investments in new dams vary with forecasts of changing runoff and other uncertainties. To demonstrate the framework, we consider the case of new multipurpose dams along the Blue Nile in Ethiopia. We model flexibility in design and operating decisions—the selection, sizing, and sequencing of new dams, and reservoir operating rules. Results show that there is no single investment plan that performs best across a range of plausible future runoff conditions. The decision-analytic framework is then used to identify dam configurations that are both robust to poor outcomes and sufficiently flexible to capture high upside benefits if favorable future climate and hydrological conditions should arise. The approach could be extended to explore design and operating features of development and adaptation projects other than dams.

  15. Butterfly effect: understanding and mitigating the local consequences of climate change impacts

    Lorenz, Donna

    2007-01-01

    Full text: The Butterfly Effect is the notion that tiny differences in initial conditions are amplified in the evolution of a dynamic system and directly affect the eventual outcome. In 1963 mathematician and meteorologist Edward Lorenz proposed that the flapping of a butterfly's wing would cause a disturbance that becomes exponentially amplified so as to eventually affect large-scale atmospheric motion. This was to illustrate the 'sensitive dependence on initial conditions'; sensitivity also true in affecting the extent of damages experienced as a result of climate change. In a climate change context, The Butterfly Effect suggests the local consequences of climate change impacts will depend on their interaction with the economic, environmental, institutional, technological and demographic attributes unique to a city or region. It is this mix of factors that will determine the extent, both positively and negatively, to which climate change will be experienced locally. For a truly effective climate change response, it is imperative that regional risk assessments and adaptation strategies take into account not only the projected impacts but the full range of flow-on implications of those impacts and their sensitivity factors. Understanding of the sensitivity factors that will amplify or mitigate climate change impacts and implications enables government and business leaders to calculate the likely extent of localised damages if no adaptation is undertaken. This allows industries and communities to evaluate the likely significance of a particular impact and to consider how to adjust or counter the sensitivity factor to build resilience and reduce vulnerability. Thus, it also assists in the local prioritisation of issues and responses. Such a strategic response can also mean the required adaptation measures may be less extensive and thereby require less cost and time to implement. This paper discusses the flow-on implications of Australia's projected climate change

  16. Powerful agent of change? The global insurance industry as a driver for greenhouse mitigation and adaptation

    Phelan, Liam; Taplin, Ros

    2007-01-01

    1964b). From the mid-nineties, environmentalists have looked to the insurance sector as a potential driver on climate change response. Yet by and large, environmentalists' hopes for action by insurers have not been met (Paterson 2001). More recent work suggests that insurers could indeed play constructive roles (Mills and Lecomte 2006). The paper reviews prospects for application of the insurance function in support of climate change mitigation and adaptation. The specific focus is potential for insurance industry action, consistent with the industry's historical interest in loss reduction and prevention

  17. Land Management Restrictions and Options for Change in Perpetual Conservation Easements

    Rissman, Adena; Bihari, Menka; Hamilton, Christopher; Locke, Christina; Lowenstein, David; Motew, Melissa; Price, Jessica; Smail, Robert

    2013-07-01

    Conservation organizations rely on conservation easements for diverse purposes, including protection of species and natural communities, working forests, and open space. This research investigated how perpetual conservation easements incorporated property rights, responsibilities, and options for change over time in land management. We compared 34 conservation easements held by one federal, three state, and four nonprofit organizations in Wisconsin. They incorporated six mechanisms for ongoing land management decision-making: management plans (74 %), modifications to permitted landowner uses with discretionary consent (65 %), amendment clauses (53 %), easement holder rights to conduct land management (50 %), reference to laws or policies as compliance terms (47 %), and conditional use permits (12 %). Easements with purposes to protect species and natural communities had more ecological monitoring rights, organizational control over land management, and mechanisms for change than easements with general open space purposes. Forestry purposes were associated with mechanisms for change but not necessarily with ecological monitoring rights or organizational control over land management. The Natural Resources Conservation Service-Wetland Reserve Program had a particularly consistent approach with high control over land use and some discretion to modify uses through permits. Conservation staff perceived a need to respond to changing social and ecological conditions but were divided on whether climate change was likely to negatively impact their conservation easements. Many conservation easements involved significant constraints on easement holders' options for altering land management to achieve conservation purposes over time. This study suggests the need for greater attention to easement drafting, monitoring, and ongoing decision processes to ensure the public benefits of land conservation in changing landscapes.

    Identification of early biomarkers of cardiotoxicity could help initiate means to ameliorate the cardiotoxic actions of clinically useful drugs such as doxorubicin (DOX). Since DOX has been shown to target mitochondria, transcriptional levels of mitochondria-related genes were evaluated to identify early candidate biomarkers in hearts of male B6C3F{sub 1} mice given a weekly intravenous dose of 3 mg/kg DOX or saline (SAL) for 2, 3, 4, 6, or 8 weeks (6, 9, 12, 18, or 24 mg/kg cumulative DOX doses, respectively). Also, a group of mice was pretreated (intraperitoneally) with the cardio-protectant, dexrazoxane (DXZ; 60 mg/kg) 30 min before each weekly dose of DOX or SAL. At necropsy a week after the last dose, increased plasma concentrations of cardiac troponin T (cTnT) were detected at 18 and 24 mg/kg cumulative DOX doses, whereas myocardial alterations were observed only at the 24 mg/kg dose. Of 1019 genes interrogated, 185, 109, 140, 184, and 451 genes were differentially expressed at 6, 9, 12, 18, and 24 mg/kg cumulative DOX doses, respectively, compared to concurrent SAL-treated controls. Of these, expression of 61 genes associated with energy metabolism and apoptosis was significantly altered before and after occurrence of myocardial injury, suggesting these as early genomics markers of cardiotoxicity. Much of these DOX-induced transcriptional changes were attenuated by pretreatment of mice with DXZ. Also, DXZ treatment significantly reduced plasma cTnT concentration and completely ameliorated cardiac alterations induced by 24 mg/kg cumulative DOX. This information on early transcriptional changes during DOX treatment may be useful in designing cardioprotective strategies targeting mitochondria. - Highlights: • Altered mitochondria-related gene expression before heart injury by doxorubicin • Dexrazoxane mitigated doxorubicin-induced early expression changes in mitochondria. • Dexrazoxane completely ameliorated doxorubicin-induced pathology in mouse heart.

  8. A multi-criteria evaluation method for climate change mitigation policy instruments

    Konidari, Popi; Mavrakis, Dimitrios

    2007-01-01

    This paper presents an integrated multi-criteria analysis method for the quantitative evaluation of climate change mitigation policy instruments. The method consists of: (i) a set of criteria supported by sub-criteria, all of which describe the complex framework under which these instruments are selected by policy makers and implemented, (ii) an Analytical Hierarchy Process (AHP) process for defining weight coefficients for criteria and sub-criteria according to the preferences of three stakeholders groups and (iii) a Multi-Attribute Theory (MAUT)/Simple Multi-Attribute Ranking Technique (SMART) process for assigning grades to each instrument that is evaluated for its performance under a specific sub-criterion. Arguments for the selected combination of these standard methods and definitions for criteria/sub-criteria are quoted. Consistency and robustness tests are performed. The functionality of the proposed method is tested by assessing the aggregate performances of the EU emission trading scheme at Denmark, Germany, Greece, Italy, Netherlands, Portugal, Sweden and United Kingdom. Conclusions are discussed

    2014-01-01

    Full Text Available The paper shows results of researching the market of glued laminated timber as the most frequent innovative timber product in constructing timber framed residential facilities in Europe and Serbia. The research included the development of production, consumption and trade flows for the most significant countries in the European Union and Serbia. Additionally, the paper gives characteristics of this innovative timber product regarding dimensions, allowed deviations of dimensions defined in adequate European standard, wood species it is made of and fire resistance. The last part of the paper shows results of econometric modeling of the impact of building timber-framed houses on the consumption of glued laminated timber in Austria as one of the countries belonging to the group of the largest consumers of this innovative timber product in Europe. Taking into consideration that the substitution of classic building materials, primarily concrete, steel and aluminum, with glued laminated timber in residential construction contributes to the reduction of carbon-dioxide emission and climate change mitigation, research results of the effects of such substitution are presented in the last chapter in this paper.

  10. The economics of climate change mitigation in developing countries - methodological and empirical results

    Halsnaes, K.

    1997-12-01

    This thesis presents a methodological and empirical discussion of the costs associated with implementing greenhouse gas reduction strategies in developing countries. It presents a methodological framework for national costing studies and evaluates a number of associated valuation methods. The methodological framework has been applied in several developing countries as part of a UNEP project in which the author has participated, and reference is made to the results of these country studies. Some of the theoretical issues associated with the determination of the costs of emission reductions are discussed with reference to a number of World Bank and UN guidelines for project analysis in developing countries. The use of several accounting prices is recommended for mitigation projects, with a distinction being made between internationally and domestically traded goods. The consequences of using different accounting prices are discussed with respect to the methodology applied in the UNEP country studies. In conclusion the thesis reviews the results of some of the most important international studies of greenhouse gas emissions in developing countries. The review, which encompasses a total of 27 country studies, was undertaken by the author for the Intergovernmental Panel of Climate Change, the IPCC. Its conclusion is that the UNEP methodological framework and associated country study results are consistent with the recommendations and conclusions of the IPCC. (EG) 23 refs.

  11. Mitigating climate change by sequestering carbon soils: A hypertext-based scientific assessment

    Rauscher, H.M.; Alban, D.H.; Johnson, D.W.

    1992-01-01

    The general objective of this project is the development of a hypertext-based scientific assessment on the subject of mitigating climate change by sequestering carbon in soils. Specifically, the authors want to (1) translate the scientific knowledge base on soil carbon cycling into a form meaningful for policy makers by using the theory of issue-based hypertext for problem solving using the argumentative approach developed by the late Horst Rittel, professor of planning and design at the University of California, Berkeley; (2) provide an organized and evaluated scientific knowledge base on soil carbon dynamics for research scientists to aid in the rapid and economical review and understanding of the subfield of science; and (3) test this new hybrid hypertext and AI methodology for use as a tool for program managers to help them evaluate a research domain to find knowledge gaps, to prioritize these knowledge gaps, to channel available research funding to these projects aimed at filling the most promising knowledge gaps in order to have the greatest possible impact on the entire knowledge base of the field, and to help explicitly measure scientific progress in terms that funding sources can understand. The authors began this project in fall 1991 and expect to complete it by fall 1993

  13. Must developing countries commit quantified targets? Time flexibility and equity in climate change mitigation

    Sugiyama, Taishi; Deshun, Liu

    2004-01-01

    Equity and efficiency dimensions of global time flexibility in GHG emission reduction are analyzed with an integrated assessment model. Global time flexibility is justifiable to some extent as found in previous studies by Wigley et al. Nevertheless, it does not necessarily serve as a rationale to delay emission reduction commitment and efforts of developed countries as they suggested. The time flexibility can be saved for developing countries, and it must be so in equity consideration; early reduction by developed countries eases burden of developing countries in both time and emission quantity dimensions. This equity-oriented argument is robust against time and spatial efficiency consideration, since the apparent benefits that might accrue to developed countries from delaying reductions will by no means be transferred to far distant future developing countries for mitigation of and adaptation to climate change. The analysis thus support entry into force of the Kyoto Protocol without participation of key low income developing countries such as China and India with legally binding quantified targets in the First Commitment Period from 2008 to 2012

  14. Public willingness to pay for CO2 mitigation and the determinants under climate change: a case study of Suzhou, China.

    Yang, Jie; Zou, Liping; Lin, Tiansheng; Wu, Ying; Wang, Haikun

    2014-12-15

    This study explored the factors that influence respondents' willingness to pay (WTP) for CO2 mitigation under climate change. A questionnaire survey combined with contingent valuation and psychometric paradigm methods were conducted in the city of Suzhou, Jiangsu Province in China. Respondents' traditional demographic attributes, risk perception of greenhouse gas (GHG), and attitude toward the government's risk management practices were established using a Tobit model to analyze the determinants. The results showed that about 55% of the respondents refused to pay for CO2 mitigation, respondent's WTP increased with increasing CO2 mitigation percentage. Important factors influencing WTP include people's feeling of dread of GHGs, confidence in policy, the timeliness of governmental information disclosure, age, education and income level.

  15. Integrated assessment of global water scarcity over the 21st century under multiple climate change mitigation policies

    Hejazi, Mohamad I.; Edmonds, James A.; Clarke, Leon E.; Kyle, G. Page; Davies, Evan; Chaturvedi, Vaibhav; Wise, Marshall A.; Patel, Pralit L.; Eom, Jiyong; Calvin, Katherine V.

    Water scarcity conditions over the 21st century both globally and regionally are assessed in the context of climate change and climate mitigation policies, by estimating both water availability and water demand within the Global Change Assessment Model (GCAM), a leading community integrated assessment model of energy, agriculture, climate, and water. To quantify changes in future water availability, a new gridded water-balance global hydrologic model – namely, the Global Water Availability Model (GWAM) – is developed and evaluated. Global water demands for six major demand sectors (irrigation, livestock, domestic, electricity generation, primary energy production, and manufacturing) are modeled in GCAM at the regional scale (14 geopolitical regions, 151 sub-regions) and then spatially downscaled to 0.5 o x 0.5o resolution to match the scale of GWAM. Using a baseline scenario (i.e., no climate change mitigation policy) with radiative forcing reaching 8.8 W/m2 (equivalent to the SRES A1Fi emission scenario) and three climate policy scenarios with increasing mitigation stringency of 7.7, 5.5, and 4.2 W/m2 (equivalent to the SRES A2, B2, and B1 emission scenarios, respectively), we investigate the effects of emission mitigation policies on water scarcity. Two carbon tax regimes (a universal carbon tax (UCT) which includes land use change emissions, and a fossil fuel and industrial emissions carbon tax (FFICT) which excludes land use change emissions) are analyzed. The baseline scenario results in more than half of the world population living under extreme water scarcity by the end of the 21st century. Additionally, in years 2050 and 2095, 36% (28%) and 44% (39%) of the global population, respectively, is projected to live in grid cells (in basins) that will experience greater water demands than the amount of available water in a year (i.e., the water scarcity index (WSI) > 1.0). When comparing the climate policy scenarios to the baseline scenario while maintaining

    Weaver, A. J.

    Subsequent to the release of the 2007 Report of the Intergovernmental Panel on Climate Change, the Province of British Columbia in Canada became an international leader in the development and implementation of innovative climate change mitigation policies. These include, but are not limited to, the 2008 Greenhouse Gas Reductions Target Act, the 2008 Carbon Tax Act and the 2010 Clean Energy Act. British Columbia's Cleantech sector quickly responded to, and thrived as a result of, the signal sent by government to the market. But with a change in Premier in 2011 came a change in priorities. A number of the previous initiatives have either been weakened or no longer followed through with as the Province sets its vision of being a major exporter of Liquified Natural Gas. As a member of the British Columbia Climate Action Team set up by Premier Gordon Campbell in 2007 to provide advice to government on a variety of policy-related matters, I was fortunate to be able to watch first hand as the Province aggressively moved towards reducing its Greenhouse gas emissions. Rather than stand on the sidelines as the government lost its direction on the climate file I chose to run with the BC Green Party in the 2013 provincial election. I was subsequently elected as a Member of the Legislative Assembly representing the constituents of Oak Bay Gordon Head. While science can and should inform policy deliberations, in and of itself, science cannot and should not prescribe policy outcomes. Whether or not we deal with today's challenge of climate change boils down to a question of intergeneration equity. Does the present generation owe anything to future generations in terms of the quality of the environment that they inherit? Many of today's elected decision-makers are focused on short-term decision-making. Yet those who will be affected by the consequences of these decisions are not part of the decision making process — hence the political conundrum. In this presentation I detail

  17. Pleistocene Park: the restoration of steppes as a tool to mitigate climate change through albedo effect

    Zimov, N.; Loranty, M. M.; Edgar, C.; Kropp, H.; Zimov, S. A.

    2017-12-01

    In the late Pleistocene, the world largest ecosystem was the mammoth steppe. It stretched from the Iberian Peninsula to Canada and from the New Siberian Islands to China. It was a highly productive steppe ecosystem with numerous predators and herbivores that maintained the dominance of grasslands. With the end of the Pleistocene, the climate warmed and humans entered Siberia and the Americas. The introduction of humans as predators in these regions led to the extinction of most large animals, and the further degradation of the steppes. Mosses, shrubs and larch forest soon replaced grasses and herbs. Pleistocene Park is an experiment conducted in the far north of Siberia; its main goal is to revive the extinct steppe ecosystem in the Arctic. This would increase the richness of the northern ecosystems and, bioproductivity, and through a series of ecological mechanisms help to mitigate climate change. To conduct the experiment, was fenced 2000 hectares of land, and continue the ongoing process of introducing animals that either lived on this territory in the past or that can adapt to the modern northern environment. Through grazing, animals slowly transform the vegetation, replacing mosses, shrubs, and trees with grasses and herbs. Here we present the effects grazing animals have on the albedo of the landscape. Several years of year-round measurement of albedo and incoming and reflected radiation conducted in the grasslands in the park indicate substantially higher albedo compared with most modern ecosystems like larch forest and shrublands. Since grasses are lighter than forest, they reflect a higher portion of energy back to space. Results indicate the most dramatic difference in reflected solar radiation is in April and early May. Grasslands covered with snow reflect most of the sun's energy, while dark stems of forests and shrubs absorb that energy and promote warming. We argue that large-scale promotion of highly productive steppes in the Arctic will

    Kouloumpis, Victor; Stamford, Laurence; Azapagic, Adisa

    2015-01-01

    As nations face the need to decarbonise their energy supply, there is a risk that attention will be focused solely on carbon and climate change, potentially at the expense of other environmental impacts. To explore the trade-offs between climate change mitigation and other environmental impacts, this work focuses on electricity and considers a number of scenarios up to 2070 in a UK context with different carbon reduction targets and electricity demand to estimate the related life cycle enviro...

  19. Community based ecological restoration of peatland in Central Mongolia for climate change mitigation and adaptation

    Peatlands cover almost 2 % of Mongolia. They play crucial role in regulation of key natural processes in ecosystems and provide unique resources to maintain traditional way of life and livelihoods of herders. During the last decades, Mongolian peatlands severely degraded both due to the climate related events and due to overgrazing. The peat degradation causes significant losses of carbon store, GHG emissions and is followed by changes in water balance and water composition. The issue arises if such a type of ecosystems as peatlands could be a subject for ecosystem restoration in this arid and subhumid climate. Could it be considered as measure for climate change mitigation and adaptation? With funding opportunities from the Asian Development Bank a pilot project for peatland restoration had been launched in 2016 in Khashaat soum, Arkhangai aimag in Central Mongolia. The pilot aimed to merge local interests of herders with global targets of climate change mitigation. The following questions are addressed: what are the losses of natural functions and ecosystem services of peatland; what are expectations and demands of local communities and incentives for their involvement; how should and could look the target ecosystem; what are the technical solutions in order to achieve the target ecosystem characteristics; and what are the parameters for monitoring to assess the success of the project? The comprehensive baseline study addressed both natural and social aspects. The conclusions are: most of peat in the study area had been mineralised and has turned to organic rich soil with carbon content between 20 to 40 %, the key sources of water - small springs - are partly destroyed by cattle; the permafrost disappeared in this area and could not be the subject for restoration; local herders understand the value of peatland as water source and had carried out some voluntary activities for water storage and regulation such as dam construction; nevertheless there is no

    Insight is given into the local policy options with respect to climate change, in this case within the sphere of influence of Amsterdam local authorities. A list of new policy options for CO2-reduction has been made with the assistance of local policy makers and representatives of interest groups. These policy options have been divided into three qualitative scenarios: Institutional Cultural Change, Technological Innovation and Least Regrets. The environmental, economic and other effects have been described for each policy option. The three most interesting policy options have been selected by local policy makers and representatives of interest groups during a workshop. Implementation strategies have been developed for the options selected. These strategies have been discussed during a second workshop. The reduction target, stabilization of CO2-emissions in 2015 compared to 1993, can be realized by a combination of all the new policy options. The three selected policy options count for 40% of this total CO2-emission reduction. Finally, a general outline on the methodology to construct local policies for climate protection has been described. This methodology can also be applied to other cities and municipal administrators, e.g. participants of Cities for Climate Protection, an initiative of the International Council for Local Environmental Initiatives, or the Netherlands Climate Association. 136 refs

    Reducing (and eventually reversing) the increase in greenhouse gases (GHGs) in the atmosphere due to human activities, and thus reducing the extent and severity of anthropogenic climate change, is one of the great challenges facing humanity. While most of the man-caused increase in GHGs has been due to fossil fuel use, land use (including agriculture) currently accounts for about 25% of total GHG emissions and thus there is a need to include emission reductions from the land use sector as part of an effective climate change mitigation strategy. In addition, analyses included in the recent IPCC 5th Climate Change Assessment report suggests that it may not be possible to achieve large enough emissions reductions in the energy, transport and industrial sectors alone to stabilize GHG concentrations at a level commensurate with a less than 2°C global average temperature increase, without the help of a substantial CO2 sink (i.e., atmospheric CO2 removal) from the land use sector. One of the potential carbon sinks that could contribute to this goal is increasing C storage in soil organic matter on managed lands. This report details a preliminary scoping analysis, to assess the potential agricultural area in the US – where appropriate soil, climate and land use conditions exist – to determine the land area on which ‘improved root phenotype’ crops could be deployed and to evaluate the potential long-term soil C storage, given a set of ‘bounding scenarios’ of increased crop root input and/or rooting depth for major crop species (e.g., row crops (corn, sorghum, soybeans), small grains (wheat, barley, oats), and hay and pasture perennial forages). The enhanced root phenotype scenarios assumed 25, 50 and 100% increase in total root C inputs, in combination with five levels of modifying crop root distributions (i.e., no change and four scenarios with increasing downward shift in root distributions). We also analyzed impacts of greater root

  2. Attitudes to climate change, perceptions of disaster risk, and mitigation and adaptation behavior in Yunlin County, Taiwan.

    Lee, Yung-Jaan; Tung, Chuan-Ming; Lin, Shih-Chien

    2018-02-08

    Issues that are associated with climate change have global importance. Most related studies take a national or regional perspective on the impact of climate change. Taiwan is constrained by its geographical conditions, which increase its vulnerability to climate change, especially in its western coastal areas. The county that is most affected by climate change is Yunlin. In 2013-2014, projects that were sponsored by Taiwan's government analyzed the relationship among synthesized vulnerability, ecological footprint (EF) and adaptation to climate change and proposed 15 categories of synthesized vulnerability and EF values. This study further examines the relationship between vulnerability and EF values and examines how residents of four townships-Linnei, Sihu, Mailiao, and Huwei-cope with the effects of climate change. This study investigates whether the residents of the four townships vary in their attitudes to climate change, their perceptions of disaster risk, and their behavioral intentions with respect to coping with climate change. The structural equation model (SEM) is used to examine the relationships among attitudes to climate change, perceptions of disaster risk, and the behavioral intentions of residents in townships with various vulnerabilities to climate change. The results that are obtained using the SEM reveal that climate change mitigation/adaptation behavior is affected by attitudes to climate change and perceptions of disaster risk. However, the effects of attitudes and perceptions on mitigation and adaptation that are mediated by place attachment are not statistically significant.

    Carbon sequestration in forest sinks is an important strategy to remove greenhouse gases and to mitigate climate change; however its implementation has been limited under the Clean Development Mechanism of the Kyoto Protocol which has not created the incentives for widespread implementation. The objective of this paper is to analyze the sequestration costs of agroforestry afforestation and reforestation projects (ARPs) following a partial market equilibrium using average cost curves and economic break even analysis to identify the supply costs. The modelling done in this work contrasts the voluntary and clean development mechanism transaction costs. Data is based on the voluntary project, Scolel Te, being implemented in Mexico. Cost curves are developed for seven different sequestration options considering transaction and implementation costs; information from agricultural production in Chiapas Mexico is used to integrate opportunity costs of two agroforestry practices suggesting that sequestration costs may follow a 'U' shape, with an initial reduction due to economies of scale and a subsequent increase caused by high opportunity costs. The widespread implementation of agroforestry options not requiring complete land conversion (e.g. living fences and coffee under shade) might be cost effective strategies not generating high opportunity costs. Results also suggest that payments in the early years of the project and lower transaction costs favour the development of ARPs in the voluntary market especially in marginal rural areas with high discount rates.

  4. Dietary 2-oxoglutarate mitigates gastrectomy-evoked structural changes in cartilage of female rats.

    Dobrowolski, Piotr; Tomaszewska, Ewa; Kurlak, Paulina; Pierzynowski, Stefan G

    2016-01-01

    Gastrectomy (Gx) leads to osteopenia/osteoporosis in humans and animals. However, little is known about the influence of Gx on the cartilage in this regard. Recent studies have demonstrated a protective effect of 2-oxoglutaric acid (2-Ox) on bone and cartilage. Hence, the purpose of this study was to investigate whether 2-Ox can mitigate eventual Gx-induced cartilage impairment. Twenty female Sprague-Dawley rats were subjected to Gx and randomly divided into two groups: Gx + 2-Ox and Gx. Another 20 rats were sham-operated (ShO) and randomly divided into two groups: ShO + 2-Ox and ShO. The daily dose of 2-Ox administered to the rats in the drinking water was 0.43 g per 100 g rat. After eight weeks, rats were euthanized and femora and tibiae were collected. Histology and histomorphometry analyses of the articular cartilage and the growth plate were done. Gx resulted in a 32% (±44.5 femur, ±35.8 tibia) decrease in overall thickness of articular cartilage in both bones (femur: ShO 279.1 ± 48.5 vs. Gx 190.2 ± 38.4 µm, tibia: ShO 222.9 ± 50.3 µm vs. Gx 151.3 ± 52.6 µm) (in some zones up to 58 ± 28.0%), and in the growth plate up to 20% (±22.4) (femur: ShO 243.0 ± 34.0 vs. Gx 207.0 ± 33.7 µm, tibia: ShO 220.0 ± 24.6 µm vs. Gx 171.1 ± 16.1 µm). Gx altered the spatial distribution of thick and thin collagen fibers, and chondrocyte shape and size. 2-Ox administration prevented the reduction in both cartilages thickness (Gx + 2-Ox: articular cartilage 265.2 ± 53.8 µm, 235.6 ± 42.7 µm, growth plate 236.7 ± 39.2 µm, 191.3 ± 16.5 µm in femur and tibia, respectively), and abolished the spatial changes in collagen distribution and structure induced by Gx. Gx affects cartilage structure and thickness, however, 2-Ox administration mitigates these effects and showed protective and stimulatory properties. Our observations suggest that dietary 2-Ox can be used to offset

  5. Climate change and the biosphere option: moving to a sustainable future

    Human activities resulting in greenhouse gas (GHG) emissions have been implicated as the primary factor forcing climate change. This evidence led to a landmark international agreement in Kyoto, (1997) committing the developed countries of the world to reductions in GHG emissions. In Canada, fossil fuel use over the past few centuries has released about 5200 Mt C into the atmosphere. An equivalent amount has probably been added as a result of deforestation and agricultural practice in this country. If we can manage our biosphere better and return even a fraction of the lost biosphere C, we can make a significant contribution to reducing Canada's current annual GHG emission. In the process, plants ( including trees) will trap the sun's energy and build an energy-rich biomass that we can learn to utilize as an energy, chemical and material resource for the future. In doing so, we will relieve the escalating demand for fossil fuels. The BIOCAP Network will be a multidisciplinary group of university, government and industry researchers dedicated to exploring the scientific, technological and policy implications of this 'biosphere option'. Canada's 'biosphere option' for GHG management is both a national opportunity and a global responsibility

  6. SUSTAINABLE DIVERSIFIED AGRICULTURE AND LAND MANAGEMENT IN THE HIMALAYA: IMPLICATIONS FOR CLIMATE CHANGE ADAPTATION AND MITIGATION

    Full Text Available The soil and land resources play a vital role in sustaining the local livelihoods of rural communities in the Himalaya. Most of the arable land has already been brought under cultivation, hence the ever-increasing demand for food and fiber has left farmers with no choice but to intensify agriculture. However, producing more crops and greater quantities of food, fiber and other materials on the same parcel of land can to soil fertility and productivity decline with overall degradation of land quality. Therefore, ways and means to intensify agriculture to enhance productivity without degrading the soil and land resource base have become imperative. Agro-forestry, agro-slivi-pastoral systems, and the adoption of a variety of crop, soil and water management and conservation practices offer potential to deliver multiple benefits without sacrificing the very resource upon which the human population depends. Presented herein are findings on approaches to sustainable intensification of agriculture and land management related to soil OM management and C sequestration for multiple benefits, and, agro-forestry as a crop diversification strategy with both livelihood, and climate change adaptation/mitigation benefits. The results indicate that sustainable soil management practices could lead to significant SOC accumulations (4-8 t/ha over 6 yrs. SOC and soil C stocks tend to increase with elevation due to cooler climate and slow decomposition rates. Carbon stocks for the 3 LU types was in the order CF>AF/LH>AG, suggesting that diversified cropping practices including agro-forestry have good potential sequester C while providing livelihood opportunities and climate adaptive capacity for local farming communities. Biochar amendment increased growth of both coffee plants and radish with mixed grass/weed biochar being most effective. Biochar application also significantly decreased emission of GHGs, especially N2O.

    In this paper we analyse macroeconomic consequences of greenhouse gas emission mitigation in Latin America up to 2050 through a multi-model comparison approach undertaken in the context of the CLIMACAP–LAMP research project. We compare two carbon tax scenarios with a business-as-usual scenario of anticipated future energy demand. In the short term, with carbon prices reaching around $15/tCO_2 by 2030, most models agree that the reduction in consumer spending, as a proxy for welfare, is limited to about 0.3%. By 2050, at carbon prices of $165/tCO_2, there is much more divergence in the estimated impact on consumer spending as well as GDP across models and regions, which reflects uncertainties about technology costs and substitution opportunities between technologies. We observe that the consequences of increasingly higher carbon prices, in terms of reduced consumer spending and GDP, tend to be fairly linear with the carbon price in our CGE models. However, the consequences are divergent and nonlinear in our econometric model, that is linked to an energy system model that simulates step-changes in technology substitution. The results of one model show that climate policy measures can have positive effects on consumer spending and GDP, which results from an investment stimulus and the redistribution of carbon price revenues to consumers. - Highlights: • Depending on the model approach negative and positive macro-economic impacts are possible if carbon taxes are introduced. • Limited impact of moderate carbon taxes (up to $15/tCO_2 by 2030) on consumer spending in the medium-term • Impact of High CO_2 prices (around $165/tCO_2 in 2050) on GDP 5% at most in the long-term

  8. DETERMINANTS OF CHOICE OF CROP VARIETY AS CLIMATE CHANGE ADAPTATION OPTION IN ARID REGIONS OF ZIMBABWE

    Full Text Available Impacts of climate change in developing countries remain poorly understood because few studies have successfully analyses the overall impact of climate on developing country economies. Agricultural growth is widely viewed as an effective and most important way to reduce poverty in developing countries which are hardly hit by the adverse effects of climate change (Datt and Ravallion, 1996. Despite this knowledge the main challenge is how to increase agricultural productivity to improve household welfare and increase food security in these changing and challenging climatic conditions. This study used the multinomial logit model to analyse the determinants of farmers' choice of crop variety in the face of climate change. The estimation of the multinomial logit was done by using the sorghum variety options as dependent variable and where farmers grow other crop different from sorghum as the reference state. Results show that the key determinants of choosing crop variety are; the price of existing crop variety, level of education of farmers, the size of the farms, government policies and incentives and credit availability.

    Previous research has documented the feasibility of screening in emergency departments for adolescent suicide risk. This randomized trial examined the effectiveness of Teen Options for Change (TOC), an intervention for adolescents seeking general medical emergency services who screen positive for suicide risk. Participants were 49 youths, ages 14 to 19, seeking services for nonpsychiatric emergencies. They screened positive for suicide risk because of recent suicidal ideation, suicide attempt, or depression plus substance abuse. Youths were randomly assigned to the TOC intervention or to enhanced treatment as usual. Depression, hopelessness, and suicidal ideation were assessed at baseline and two months later. Adolescents assigned to TOC showed greater reductions in depression than adolescents assigned to the comparison group (Cohen's d=1.07, a large effect size). Hopelessness, suicidal ideation, and substance abuse outcomes trended positively (nonsignificantly), with small to moderate effect sizes. TOC may be a promising, brief intervention for adolescents seeking emergency services and at risk of suicide.

    The electricity generation contributes to development and to improve the quality of life, But it is ones of the most important contributors to the Greenhouse Gas and particle emissions particularly in Cuba where 99.4% of electricity in the National Electric System is generated from fossil fuels. In the paper from mitigation measures three mitigation scenarios are evaluated for the Expansion of the Cuban electric system using DECADES Tools. Evaluated scenarios include the Use of 60% of the biomass potential, the combinations of this with nuclear power reactors, Hydraulic energy and combined cycle power plants. Finally in the paper the Greenhouse Gas level reduction, investment, fuel, operation and Maintenance costs and Carbon Intensity in generation are analyzed for evaluated mitigation Scenarios and conclusions are offered

    of contrasting strategies: single environmental objective management versus joint implementation strategy. The results show that implementing land-based measures with a sole focus on water quality (to meet the HELCOM's 2013 Baltic Sea Action Plan nutrient abatement targets) can produce climate change mitigation......This paper explores the scope for simultaneously managing nutrient abatement and climate change mitigation in the Baltic Sea (BS) region through the implementation of a selection of measures. The analysis is undertaken using a cost-minimisation model for the entire BS region, the BALTCOST model....... In the present research, the model has been extended to include greenhouse gas (GHG) emissions effects, enabling us to analyse the tradeoffs between cost-effective GHG and nutrient load reductions. We run the model for four different scenarios in order to compare the environmental and economic consequences...

    Nuclear power secures affordable carbon-free energy supply, but entails various risks and constraints, such as safety concerns, waste disposal protest campaign, and proliferation. Given the nature of these characteristics of nuclear power generation, there is wide range of variations in representation of nuclear power technologies across models. In this paper, we explore the variance of the model representation of nuclear power generation and its implication to the climate change mitigation assessment, based on the EMF27 study. The most common result is that under efforts to mitigate climate change more nuclear energy use is needed. We find, however, that perspectives on the contribution of nuclear energy to global energy needs vary tremendously among the modeling teams. This diversity mainly comes from th
