    The chapter begins with an introduction of the main arguments for why global cost-effectiveness in GHG emission reduction policies will suggest that an international collaboration about the policies is established such as initiated by the Kyoto Protocol of the United Nations Framework Convention on Climate Change. A general conceptual overview is given on the cost concepts that are relevant to apply to the evaluation of GHG emission reduction policies, and the methodological framework of GHG emission reduction cost studies for developing countries are introduced. The studies have in particular focussed on GHG emission reduction options in the energy sector, and a number of costing results are reported for this sector. Finally, the chapter considers potential local side-impacts on development, the local environment, and social policy objectives of GHG emission reduction projects seen from the perspective of developing countries. It is concluded that there is a potential for combining global cost-effectiveness principles for GHG emission reduction policies, and local policy objectives of developing countries. (LN)

    Full Text Available In this paper, a two-stage dynamic game model of China’s iron and steel industry is constructed. Carbon tax levy, product subsidy, carbon capture and sequestration (CCS and other factors are included in the emission reduction mechanism. The effects of emissions reduction and the economic impact of China’s overall steel industry (and that of its six main regions are investigated for the first time under different scenarios. As new findings, we report the following: (1 Not all factors declined. The overall social welfare, consumer surplus, output and emissions decrease with a gradual increase in the reduction target, whereas the carbon tax value, unit value of product subsidies and total subsidies show a rising trend; (2 A combination of multiple emissions reduction policies is more effective than a single policy. With the implementation of a combined policy, regional output polarization has eased; (3 Steel output does not exceed 950 million tons, far below the current peak. These results will help the industry to formulate reasonable emissions reduction and output targets. In short, in effort to eliminate industry poverty and to alleviate overcapacity, the industry should not only adopt the various coordinated reduction policies, but also fully consider regional differences and reduction needs.

    There is a growing consensus in Canada that climate change needs to be addressed through concrete actions. The implementation of specific policies have been impeded by concerns over economic costs. However, uncertainty over the course of policy creates a cost since businesses have little idea how to factor future environmental policies into their planning. This report examined the policy tools that federal and provincial governments have at their disposal to reduce greenhouse gas (GHG) emissions, including carbon pricing (through cap-and-trade systems or carbon taxes), regulated standards, subsidies, infrastructure spending, research and development, and voluntary initiatives. In order to understand the strengths and weaknesses of these policy options, the study assessed them against a set of criteria that included environmental effectiveness, economic efficiency, fairness and cost-effectiveness. The report also reviewed the real-world experience with the implementation of these policy options in Canada and internationally. In particular, the report examined carbon pricing mechanisms in detail and explored the best ways to use revenues raised through carbon pricing, and the best options to mitigate any reduced international competitiveness that Canadian industries may encounter. The report concluded with a discussion of areas for further research. It was concluded that climate policy in Canada raises a host of jurisdictional questions that would benefit from further research. 7 tabs., 2 appendices

  7. Households Willingness to Pay for the Emissions Reduction Policy, Queensland, Australia

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available This study examines households’ willingness to support the emissions reduction policy and their perceptions of climate change using an Internet survey of more than 1,000 households in Queensland, Australia. Respondents were asked for their willingness to pay (WTP to support the emissions reduction target proposed by the Australian Government by paying extra on their electricity bills. The results can be summarized in four key findings. First, respondents’ WTP to support the emissions reduction target is higher if they perceive that climate change will result in high loss of biodiversity. Second, respondents were willing to support a higher emissions target than proposed by the Australian Government. Third, there is a correlation between respondents WTP to support the emissions reduction and their beliefs about climate change, its effect on standards of living, the environment, and future generations. Fourth, as the data show a high rate of zero responses, common for the contingent valuation method (CVM used in the survey, the zero bids were further investigated using the non-parametric Turnbull model and the more recent spike model. The results showed that although there is some support for the emissions reduction policy, it is not sufficient for the policy to be successful.

  8. Mixed Carbon Policies Based on Cooperation of Carbon Emission Reduction in Supply Chain

    Full Text Available This paper established cooperation decision model for a mixed carbon policy of carbon trading-carbon tax (environmental tax in a two-stage S-M supply chain. For three different cooperative abatement situations, we considered the supplier driven model, the manufacturer driven model, and the equilibrium game model. We investigated the influence of mixed carbon policy with constraint of reduction targets on supply chain price, productivity, profits, carbon emissions reduction rate, and so on. The results showed that (1 high-strength carbon policies do not necessarily encourage enterprises to effectively reduce emissions, and increasing market acceptance of low carbon products or raising the price of carbon quota can promote the benign reduction; (2 perfect competitive carbon market has a higher carbon reduction efficiency than oligarch carbon market, but their optimal level of cooperation is the same and the realized reduction rate is in line with the intensity of carbon policy; (3 the policy sensitivity of the carbon trading mechanism is stronger than the carbon tax; “paid quota mechanism” can subsidize the cost of abatement and improve reduction initiative. Finally, we use a numerical example to solve the optimal decisions under different market situations, validating the effectiveness of model and the conclusions.

    Because of China's increasingly limited energy supplies and serious environmental pollution, much attention has been paid to conserving energy and reducing emissions to help the country's economy achieve sustainable development. As the electric power industry is the largest consumer of coal resources in China and also emits high levels of air pollutants each year, the Chinese government has enacted many technical and economic policies for energy conservation and emission reduction in the last few years. These policies are summarized in this paper, along with relevant laws and medium- and long-term plans, all of which address ideas such as adjusting the power generation mix, promoting demand-side management, introducing energy-efficient scheduling, and installing desulfurization units. The paper also assesses the results of these policies by analyzing several key indicators of energy consumption and emissions. The analysis shows that although some progress has been made in conserving energy and reducing emissions, substantial work is still required for China to catch up with developed countries. Some suggestions for future work are provided. - Highlights: → China has made many policies for reducing the power industries' energy consumption and emissions. → Progress has been made in conserving energy and reducing emission of the electric power industry. → Substantial works need to be done for China to catch up with the level of developed country. → Market mechanisms for conserving energy and reducing emission should be constructed in the future.

    Some traditional industrial regions are characterized by high industrial proportion and large CO 2 emission. They are facing dual pressures of maintaining economic growth and largely reducing CO 2 emission. From the perspective of study of typological region, taking the typical traditional industrial region—Liaoning Province of China as a case, this study establishes a system dynamics model named EECP and dynamically simulates CO 2 emission trends under different conditions. Simulation results indicate, compared to the condition without CO 2 emission reduction policies, CO 2 emission intensity under the condition of implementing CO 2 emission reduction policies of “Twelfth Five-Year Plan” is decreased by 11% from 2009 to 2030, but the economic cost is high, making the policies implementation faces resistance. Then some improved policies are offered and proved by EECP model that they can reduce CO 2 emission intensity after 2021 and decrease the negative influence to GDP, realizing the improvement objects of reducing CO 2 emission and simultaneously keeping a higher economy growth speed. The improved policies can provide reference for making and improving CO 2 emission reduction policies in other traditional industrial regions with large CO 2 emission. Simultaneously, EECP model can provide decision-makers with reference and help for similar study of energy policy. - Highlights: ► We build EECP model for CO 2 emission reduction study in traditional industry region. ► By the model, we simulate CO 2 emission trend and improve emission reduction policy. ► By improvement, both CO 2 emission intensity and economic cost can be largely reduced. ► Besides CO 2 emission is reduced effectively, higher GDP increment speed is kept. ► EECP model can be widely used for making and improving regional energy policies.

  11. Mamizu climate policy: an evaluation of Japanese carbon emissions reduction targets

    International Nuclear Information System (INIS)

    Pielke, Roger A Jr

    2009-01-01

    This letter evaluates Japan's so-called 'Mamizu' climate policies proposed in mid-2009 in terms of the implied rates of decarbonization of the Japanese economy for short-term and long-term targets. The letter uses the Kaya identity to structure the evaluation, employing both a bottom up approach (based on projections of future Japanese population, economic growth, and technology) and a top down approach (deriving implied rates of decarbonization consistent with the targets and various rates of economic growth). Both approaches indicate that the Japanese economy would have to achieve rates of decarbonization of 2.6% to meet a 2020 target of reducing emissions by 15% below 2005 levels, and 5.0% to meet a 2050 target of an 80% reduction below 2005 levels. A target of 25% below 1990 emissions proposed by the opposition party (which subsequently formed a government following elections in August 2009) implies a rate of decarbonization of 4.6% annually to 2020. The letter argues that international criticism of Japanese Mamizu climate policy proposals as being too weak was unfounded, and if anything, the proposals may have been too ambitious. In either case, climate policy would be strengthened through the support of a diversity of approaches to decarbonization.

  12. Emissions of CO2 from road freight transport in London: Trends and policies for long run reductions

    International Nuclear Information System (INIS)

    Zanni, Alberto M.; Bristow, Abigail L.

    2010-01-01

    Freight transport has been receiving increasing attention in both literature and practice following the growing recognition of its importance in urban transport planning. This paper analyses historical and projected road freight CO 2 emissions in the city of London and explores the potential mitigation effect of a set of freight transport policies and logistics solutions. Findings indicate a range of policies with potential to reduce emissions in the period up to 2050. However, this reduction would appear to only be capable of partly counterbalancing the projected increase in freight traffic. More profound behavioural measures therefore appear to be necessary for London's CO 2 emissions reduction targets to be met.

  13. A mathematical/physics carbon emission reduction strategy for building supply chain network based on carbon tax policy

    2017-03-01

    Full Text Available Under the background of a low carbon economy, this paper examines the impact of carbon tax policy on supply chain network emission reduction. The integer linear programming method is used to establish a supply chain network emission reduction such a model considers the cost of CO2 emissions, and analyses the impact of different carbon price on cost and carbon emissions in supply chains. The results show that the implementation of a carbon tax policy can reduce CO2 emissions in building supply chain, but the increase in carbon price does not produce a reduction effect, and may bring financial burden to the enterprise. This paper presents a reasonable carbon price range and provides decision makers with strategies towards realizing a low carbon building supply chain in an economical manner.

    Cities consumed 84% of commercial energy in China, which indicates cities should be the main areas for GHG emissions reduction. Our case study of Shenyang in this paper shows how a clear inventory analysis on GHG emissions at city level can help to identify the major industries and societal sectors for reduction efforts so as to facilitate low-carbon policy-making. The results showed total carbon emission in 2007 was 57 Mt CO 2 equivalents (CO 2 e), of which 41 Mt CO 2 e was in-boundary emissions and 16 Mt CO 2 e was out-of-boundary emissions. The energy sector was dominant in the emission inventory, accounting for 93.1% of total emissions. Within energy sector, emissions from energy production industry, manufacturing and construction industry accounted for 88.4% of this sector. Our analysis showed that comparing with geographical boundary, setting system boundary based on single process standard could provide better information to decision makers for carbon emission reduction. After attributing electricity and heating consumption to final users, the resident and commercial sector became the largest emitter, accounting for 28.5% of total emissions. Spatial analysis of emissions showed that industrial districts such as Shenbei and Tiexi had the large potential to reduce their carbon emissions. Implications of results are finally discussed. - Highlights: → An inventory analysis can help identify key industries and societal sectors for reduction efforts. → Setting system boundary can provide better information for carbon emission reduction. → Urban districts with heavy industrial plants have potential to reduce their carbon emissions. → Policies that support urban energy structure optimization can accelerate low-carbon development.

  15. Cost-effective policy instruments for greenhouse gas emission reduction and fossil fuel substitution through bioenergy production in Austria

    2011-01-01

    Climate change mitigation and security of energy supply are important targets of Austrian energy policy. Bioenergy production based on resources from agriculture and forestry is an important option for attaining these targets. To increase the share of bioenergy in the energy supply, supporting policy instruments are necessary. The cost-effectiveness of these instruments in attaining policy targets depends on the availability of bioenergy technologies. Advanced technologies such as second-generation biofuels, biomass gasification for power production, and bioenergy with carbon capture and storage (BECCS) will likely change the performance of policy instruments. This article assesses the cost-effectiveness of energy policy instruments, considering new bioenergy technologies for the year 2030, with respect to greenhouse gas emission (GHG) reduction and fossil fuel substitution. Instruments that directly subsidize bioenergy are compared with instruments that aim at reducing GHG emissions. A spatially explicit modeling approach is used to account for biomass supply and energy distribution costs in Austria. Results indicate that a carbon tax performs cost-effectively with respect to both policy targets if BECCS is not available. However, the availability of BECCS creates a trade-off between GHG emission reduction and fossil fuel substitution. Biofuel blending obligations are costly in terms of attaining the policy targets. - Highlights: → Costs of energy policies and effects on reduction of CO 2 emissions and fossil fuel consumption. → Particular focus on new bioenergy production technologies such as second generation biofuels. → Spatially explicit techno-economic optimization model. → CO 2 tax: high costs for reducing fossil fuel consumption if carbon capture and storage is available. → Biofuel policy: no significant reductions in CO 2 emissions or fossil fuel consumption.

    A wide range of renewable electricity policies has been adopted at the state level in the United States, but to date there has been no large-scale, empirical assessment of the effect of these policies on carbon emissions. Such an assessment is important because scholars have pointed out that increases in renewable electricity will not necessarily lead to declines in carbon emissions. We examine the effects of a range of policies across 39 states. We find significant and robust decreases in carbon emissions associated with the introduction of public benefit funds, a form of “carbon tax” adopted by 19 states to date. Our aim in this paper is not to provide a final judgment on these policies, many of which may not have been in place long enough to show strong effects, but to shift the attention of the research community away from proximate measures such as increases in clean electricity generation and onto measurement of lower carbon emissions. - Highlights: ► We ask whether state-level renewable electricity policies in the United States have succeeded in lowering carbon emissions. ► We examine net metering, retail choice, fuel generation disclosure, mandatory green power options, public benefit funds, and renewable portfolio standards. ► The introduction of public benefit funds, a kind of carbon tax, is associated with decreases in carbon emissions.

    The UK residential (household) sector is responsible for approximately 30% of total carbon dioxide emissions and is often seen as the most promising in terms of early reductions. As most direct household emissions come from only two fuel sources, this paper critically examines how existing emissions reduction policies for the sector shape - and are shaped by - relations between the three main groups of actor in this policy domain: central government, gas and electricity suppliers, and energy users. Focusing on relations between three dyads (government-suppliers, suppliers-consumers and consumers-government) enables us to examine aspects of demand reduction that have often been overlooked to date. By 'relations' we refer to services, power relationships and flows of capital and information, as well as less easily defined elements such as loyalty, trust and accountability. The paper argues that the chosen government policy path to deliver demand reduction, which heavily emphasises the suppliers' role, suffers from principal-agent problems, fails to align consumers and supplier interests toward emissions reduction, and does not yet portray a lower-carbon future in positive terms. It suggests that more attention should be paid to government-consumer relations, recognising that energy consumers are also citizens. (author)

  2. The effectiveness of policy on consumer choices for private road passenger transport emissions reductions in six major economies

    Mercure, J.-F.; Lam, A.

    2015-06-01

    The effectiveness of fiscal policy to influence vehicle purchases for emissions reductions in private passenger road transport depends on its ability to incentivise consumers to make choices oriented towards lower emissions vehicles. However, car purchase choices are known to be strongly socially determined, and this sector is highly diverse due to significant socio-economic differences between consumer groups. Here, we present a comprehensive dataset and analysis of the structure of the 2012 private passenger vehicle fleet-years in six major economies across the World (UK, USA, China, India, Japan and Brazil) in terms of price, engine size and emissions distributions. We argue that choices and aggregate elasticities of substitution can be predicted using this data, enabling us to evaluate the effectiveness of potential fiscal and technological change policies on fleet-year emissions reductions. We provide tools to do so based on the distributive structure of prices and emissions in segments of a diverse market, both for conventional as well as unconventional engine technologies. We find that markets differ significantly between nations, and that correlations between engine sizes, emissions and prices exist strongly in some markets and not strongly in others. We furthermore find that markets for unconventional engine technologies have patchy coverages of varying levels. These findings are interpreted in terms of policy strategy.

    In the early stages of the development of Japan’s environmental policy, sulfur oxide (SOx) emissions, which seriously damage health, was the most important air pollution problem. In the second half of the 1960s and the first half of the 1970s, the measures against SOx emissions progressed quickly, and these emissions were reduced drastically. The most important factor of the reduction was the conversion to a low-sulfur fuel for large-scale fuel users, such as the electric power industry. Howe...

  5. Inventory and Policy Reduction Potential of Greenhouse Gas and Pollutant Emissions of Road Transportation Industry in China

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available In recent years, emissions from the road transportation industry in China have been increasing rapidly. To evaluate the reduction potential of greenhouse gas and pollutant emissions of the industry in China, its emission inventory was calculated and scenario analysis was created for the period between 2012 and 2030 in this paper. Based on the Long-range Energy Alternatives Planning System (LEAP model, the development of China’s road transportation industry in two scenarios (the business-as-usual (BAU scenario and the comprehensive-mitigation (CM scenario was simulated. In the Comprehensive Mitigation scenario, there are nine various measures which include Fuel Economy Standards, Auto Emission Standards, Energy-saving Technology, Tax Policy, Eco-driving, Logistics Informatization, Vehicle Liquidation, Electric Vehicles, and Alternative Fuels. The cumulative energy and emission reductions of these specific measures were evaluated. Our results demonstrate that China’s road transportation produced 881 million metric tons of CO2 and emitted 1420 thousand tons of CO, 2150 thousand tons of NOx, 148 thousand tons of PM10, and 745 thousand tons of HC in 2012. The reduction potential is quite large, and road freight transportation is the key mitigation subsector, accounting for 85%–92% of the total emission. For energy conservation and carbon emission mitigation, logistics informatization is the most effective method, potentially reducing 1.80 billion tons of coal equivalent and 3.83 billion tons of CO2 from 2012 to 2030. In terms of air pollutant emission mitigation, the auto emission standards measure performs best with respect to NOx, PM10, and HC emission mitigation, and logistic informatization measure is the best in CO emission reduction. In order to maximize the mitigation potential of China’s road transportation industry, the government needs to implement various measures in a timely and strict fashion.

  6. Achieving deep reductions in US transport greenhouse gas emissions: Scenario analysis and policy implications

    2009-01-01

    This paper investigates the potential for making deep cuts in US transportation greenhouse gas (GHG) emissions in the long-term (50-80% below 1990 levels by 2050). Scenarios are used to envision how such a significant decarbonization might be achieved through the application of advanced vehicle technologies and fuels, and various options for behavioral change. A Kaya framework that decomposes GHG emissions into the product of four major drivers is used to analyze emissions and mitigation options. In contrast to most previous studies, a relatively simple, easily adaptable modeling methodology is used which can incorporate insights from other modeling studies and organize them in a way that is easy for policymakers to understand. Also, a wider range of transportation subsectors is considered here-light- and heavy-duty vehicles, aviation, rail, marine, agriculture, off-road, and construction. This analysis investigates scenarios with multiple options (increased efficiency, lower-carbon fuels, and travel demand management) across the various subsectors and confirms the notion that there are no 'silver bullet' strategies for making deep cuts in transport GHGs. If substantial emission reductions are to be made, considerable action is needed on all fronts, and no subsectors can be ignored. Light-duty vehicles offer the greatest potential for emission reductions; however, while deep reductions in other subsectors are also possible, there are more limitations in the types of fuels and propulsion systems that can be used. In all cases travel demand management strategies are critical; deep emission cuts will not likely be possible without slowing growth in travel demand across all modes. Even though these scenarios represent only a small subset of the potential futures in which deep reductions might be achieved, they provide a sense of the magnitude of changes required in our transportation system and the need for early and aggressive action if long-term targets are to be met.

  7. Estimating the benefits of greenhouse gas emission reduction from agricultural policy reform

    Adger, W.N.; Moran, D.C.

    1993-01-01

    Land use and agricultural activities contribute directly to the increased concentrations of atmospheric greenhouse gases. Economic support in industrialized countries generally increases agriculture's contribution to global greenhouse gas concentrations through fluxes associated with land use change and other sources. Changes in economic support offers opportunities to reduce net emissions, through this so far has gone unaccounted. Estimates are presented here of emissions of methane from livestock in the UK and show that, in monetary terms, when compared to the costs of reducing support, greenhouse gases are a significant factor. As signatory parties to the Climate Change Convection are required to stabilize emissions of all greenhouse gases, options for reduction of emissions of methane and other trace gases from the agricultural sector should form part of these strategies

    The effect of national energy policies on a local Swedish district heating (DH) system has been studied, regarding the profitability of new investments and the potential for climate change mitigation. The DH system has been optimised regarding three investments: biomass-fuelled CHP (bio CHP), natural gas-fuelled combined cycle CHP (NGCC CHP) and biomass-fuelled heat-only boiler (bio HOB) in two scenarios (with or without national taxes and policy instruments). In both scenarios EU's tradable CO 2 emission permits are included. Results from the study show that when national policies are included, the most cost-effective investment option is the bio CHP technology. However, when national taxes and policy instruments are excluded, the DH system containing the NGCC CHP plant has 30% lower system cost than the bio CHP system. Regardless of the scenario and when coal condensing is considered as marginal electricity production, the NGCC CHP has the largest global CO 2 reduction potential, about 300 ktonne CO 2 . However, the CO 2 reduction potential is highly dependent on the marginal electricity production. Demonstrated here is that national policies such as tradable green certificates can, when applied to DH systems, contribute to investments that will not fully utilise the DH systems' potential for global CO 2 emissions reductions. - Research highlights: →Swedish energy policies are promoting biomass fuelled electricity generating technologies over efficient fossil fuel electricity generating technologies. →An efficient fossil fuel technology like the natural gas combine cycle CHP technology with high power-to-heat ratio has potential to reduce the global CO 2 emissions more than a biomass fuelled electricity generating technology. →Swedish energy policies such as tradable green certificates for renewable electricity can, when applied to district heating systems, contribute to investments that will not fully utilise the district heating systems potential for

  9. Something from nothing: Estimating consumption rates using propensity scores, with application to emissions reduction policies.

    Directory of Open Access Journals (Sweden)

    Nicholas Bardsley

    Full Text Available Consumption surveys often record zero purchases of a good because of a short observation window. Measures of distribution are then precluded and only mean consumption rates can be inferred. We show that Propensity Score Matching can be applied to recover the distribution of consumption rates. We demonstrate the method using the UK National Travel Survey, in which c.40% of motorist households purchase no fuel. Estimated consumption rates are plausible judging by households' annual mileages, and highly skewed. We apply the same approach to estimate CO2 emissions and outcomes of a carbon cap or tax. Reliance on means apparently distorts analysis of such policies because of skewness of the underlying distributions. The regressiveness of a simple tax or cap is overstated, and redistributive features of a revenue-neutral policy are understated.

  11. The Energy Policy Act of 1992 and reductions in greenhouse gas emissions: The petroleum industry perspective

    Baer, M.T.

    1994-01-01

    The Energy Policy Act of 1992 (EPAct) directs the US Department of Energy policies, programs and regulations to stabilize and reduce the quantities of greenhouse gas emissions. These objectives will be accomplished through the regulation of sources associated with the production, transportation/distribution, and end-use of energy resources. Almost all of the 30 titles of the Act affect these sources: from the energy efficiency provisions of Titles 1 and XXI to the alternative fuels and vehicles programs of Titles 3 through 5; from the global climate change requirements of Title XVI to the petroleum alternative research programs of Titles VI, XII, XIII, XX, and XXI; and from the multiple titles pertaining to the development and regulation of nuclear facilities, supplies, and waste. The goals of the law are to: (1) reduce the use of oil in the domestic energy mix from 40% in 1990 to 35% by the year 2005, (2) require the use of alternative fuels and alternative fuel vehicles in designated fleets, (3) replace up to 30% of motor fuels with ''replacement fuels'' by the year 2010, (4) increase the overall efficiency of consumer, residential, and commercial products, (5) reduce and stabilize the emissions of greenhouse gases, and (6) encourage the development and commercialization of renewable and non petroleum energy resources. All these goals are intended to reduce the emissions of greenhouse gases as well. The EPAct's potential to impact all forms of energy and all energy producers and suppliers is obvious and substantial. This paper assesses three goals of the EPAct, now under study by the petroleum industry, that will affect the production, supply, composition, and use of petroleum products, most notably gasoline and natural gas

    In the United States, the response of the federal government to the global initiative of reduction of emissions of CO 2 has been limited. With the Kyoto Protocol having entered into force in February 2005, there will be renewed international pressure on the United States for action. Concurrently, the US economy, growing modestly, is characterized by large current account and budget deficits. This situation calls for garnering additional revenue through repealing of the recent tax cuts. An option available is to impose a modest carbon tax. The rationale of such a tax is that it would address the twin objectives of additional revenue and reduction of emissions. In this paper, the impact of a hypothetical carbon tax imposed in a revenue-neutral context on 2001 household incomes is analyzed primarily to ascertain its progressivity. Progressivity of any tax is strongly associated with its political acceptability. The incidence of the hypothetical carbon tax is computed across the income quintiles. It is observed that only the households in the highest income quintile and the lowest income quintile are impacted by the tax. It is found that this tax is weakly regressive in the US context

    This study describes the development of tool for testing different policies for reduction of greenhouse gas (GHG) emissions in energy sector using artificial neural networks (ANNs). The case study of Croatia was elaborated. Two different energy consumption scenarios were used as a base for calculations and predictions of GHG emissions: the business as usual (BAU) scenario and sustainable scenario. Both of them are based on predicted energy consumption using different growth rates; the growth rates within the second scenario resulted from the implementation of corresponding energy efficiency measures in final energy consumption and increasing share of renewable energy sources. Both ANN architecture and training methodology were optimized to produce network that was able to successfully describe the existing data and to achieve reliable prediction of emissions in a forward time sense. The BAU scenario was found to produce continuously increasing emissions of all GHGs. The sustainable scenario was found to decrease the GHG emission levels of all gases with respect to BAU. The observed decrease was attributed to the group of measures termed the reduction of final energy consumption through energy efficiency measures.

    To date, greenhouse gas (GHG) emissions, mitigation strategies and the accompanying health co-benefits in different economic sectors have not been fully investigated. The purpose of this paper is to review comprehensively the evidence on GHG mitigation measures and the related health co-benefits, identify knowledge gaps, and provide recommendations to promote further development and implementation of climate change response policies. Evidence on GHG emissions, abatement measures and related health co-benefits has been observed at regional, national and global levels, involving both low- and high-income societies. GHG mitigation actions have mainly been taken in five sectors: energy generation, transport, food and agriculture, household and industry, consistent with the main sources of GHG emissions. GHGs and air pollutants to a large extent stem from the same sources and are inseparable in terms of their atmospheric evolution and effects on ecosystem; thus, GHG reductions are usually, although not always, estimated to have cost effective co-benefits for public health. Some integrated mitigation strategies involving multiple sectors, which tend to create greater health benefits. The pros and cons of different mitigation measures, issues with existing knowledge, priorities for research, and potential policy implications were also discussed. Findings from this study can play a role not only in motivating large GHG emitters to make decisive changes in GHG emissions, but also in facilitating cooperation at international, national and regional levels, to promote GHG mitigation policies that protect public health from climate change and air pollution simultaneously.

    Full Text Available As of June 2017, 150 countries have ratified the Paris Climate Agreement. This agreement calls for, among other things, strong reductions in CO2 emissions by 2030 and beyond. This paper reviews the Nationally Determined Contribution (NDCs plans of six Association of Southeast Asian Nations (ASEAN countries and compares their current and projected future CO2 levels across sectors, and their stated targets in the context of their economic and demographic situations. This comparison reveals wide variations in the types of targets, with the “ambition” level changing as the perspective changes from total CO2 to CO2/capita and per unit gross domestic product (GDP. We also review national plans as stated in NDCs and find that while there are many types of policies listed, few are quantified and no attempts are made to score individual or groups of policies for their likelihood in achieving stated targets. We conclude that more analysis is needed to better understand the possible impacts of current policies and plans on CO2 emissions, and whether current plans are adequate to hit targets. Considerations on better aligning targets are also provided.

  17. The costs of emission reduction policies, markets for emission rights: what can we learn from the models?

    Blanchard, O.

    2001-01-01

    Several models have been developed to assess the economic impacts of the commitments undertaken at Kyoto by the various parties to the Framework Agreement on Climatic Change. Following a seminar organised by the European Commission, the task here is to take stock of the various points of agreement or the differences made apparent by the models concerning the economic challenges relating to the Kyoto protocol. Qualitatively, the results are similar on several points: the implementation of the Kyoto protocol within the countries of appendix B represents a cost for these economies, except for those countries possessing hot air compared to an autarkic situation, the exchange of emission rights leads to a gain for each of the participants in the market but the setting of a ceiling for these exchanges brings about a reduction in global gains from exchange and strongly affects the division of these gains between countries. Finally, the recognition of families of greenhouse gas other than CO 2 reduces the costs of observing the Kyoto commitments. However, the quantitative results frequently diverge, both due to the type of model used (general or sector based balance) and the hypotheses chosen for the exogenous variables. It is therefore important to carry out awareness analyses, to propose sets of common hypotheses for certain exogenous variables and even to define a reference scenario common to all of the models in order to be able to re-examine the results, but this time on a common basis. The tasks of modelling should also be continued and enhanced in the following areas: What are the impacts of an emission rights market at a sector-based level (beginning with industry)? What is the exact effect of the inclusion of the six families of greenhouse gas and the absorption of carbon by the wells? Finally, what are the possibilities of differing objectives concerning a second round of commitments (post Kyoto)? (author)

    2004-05-01

    After having highlighted the main difficulties met when trying to take decisions on emission reductions (i.e. disequilibrium between short term action and long term dynamics, series of uncertainties, lack of a clear information on threats), this research aims at studying the extent and the agenda of CO 2 emission reduction efforts at a global scale. First, the author explores under various perspectives the relationship between the extent of climate change and the extent of its impacts and modes of analysis of climate policies. Then, he examines how different attitudes towards the climate risk are translated into recommendations for action which are obtained by always more complex models. In order to compare results, simulations are performed, based on optimal control models belonging to the RESPONSE family. Three different options or attitudes are then studied and assessed with RESPONSE: firstly, the uncertainty on impact and damage assessment is still too important to have confidence in present assessments; secondly, while being sceptical on damage assessment, more confidence is given to climate model results, and thirdly, an explicit representation of climate damages is used to introduce rationality issues in the debate on risks

    For more than 20 years there has been a concerted international effort toward addressing climate change. International conventions, such as the United Nations Foreign Convention on Climate Change (UNFCCC; ratified in 1994), have been established by committed nations seeking to address global climate change through the reduction of greenhouse gases emitted into the Earth's atmosphere (Global CCS Institute, 2011). Long recognised as the most crucial of the greenhouse gases to impact global warming, the majority of carbon dioxide's anthropogenic global emissions are directly related to fuel combustion of which both Australia and the Netherlands' energy production is significantly reliant. Both these nations will need to consider many opinions and make hard decisions if alternative energy options are to be implemented at the scale that is required to meet international emission targets. The decisions that are required not only need to consider the many options available but also their consequences. Along with politicians, policy developers and industry, the general public also need to be active participants in deciding which energy options, and their subsequent consequences, are acceptable for implementation at the national level. Access to balanced and factual information is essential in establishing informed opinions on the many policy options available. Past research has used several methods to measure public perceptions and opinions yet for complex issues, such as emission reduction, some of these methods have shown to be problematic.

    This paper outlines a methodological framework for the economic evaluation of CO 2 emissions abatement policies and measures in the residential sector, taking into consideration both economic and social costs/benefits. The approach includes two stages: first, the measures under consideration are evaluated on the basis of a cost effectiveness analysis, which takes into account only the related net financial costs, thus highlighting win-win actions (i.e. measures presenting an economic benefit for end users without the provision of any economic subsidies or other similar policies); and second, the measures are re-evaluated using an integrated cost benefit analysis (where both the private and external costs/benefits are taken into account). The economic performance of the measures examined incorporates the effects of a variety of parameters, such as the region's climate, size and age of buildings, etc., which significantly affect the resulting ranking. The implementation of this framework in the Greek residential sector identified and prioritized a significant emissions reduction potential, which could be achieved with win-win measures and/or interventions that present a net social benefit. Measures with negative economic cost but positive net social benefit for the majority of the buildings examined include: (i) regular inspection of central heating boilers, (ii) use of thermostats in central heating boilers, (iii) sealing of openings, (iv) installation of solar collectors for hot water etc. The monetization of environmental benefits is shown to provide a powerful tool for highlighting priority actions in the context of a climate change mitigation policy

    The German presentations will cover three main topics. These are: (1) Energy policy on the national level and in the European Community. (2) Rational use of energy and efficiency improvements by cross cutting technologies. (3) Optimizing heat recovery and heat recovery network with Pinch technology. Actual development of carbon dioxide emissions and scenarios to forecast for the future development will be presented. It will be shown, that long term agreements are widely used in the EC to obtain a reduction of emissions. Specific attention will also be placed on the burden sharing in the EC and the other GHG. In the second part the efficiency improvement by cross cutting technologies will be discussed for furnaces, waste heat recovery, electric motors, compressed air systems, cooling systems, lighting and heat pumps. Most of these improvement potentials are economic at present energy prices, but some barriers for their application have to be overcome which will be discussed. In the last part a systematic method for the optimization of heat recovery networks is presented. The Pinch technology, developed in the late seventies is an easy and reliable way to obtain quickly a good insight into the heat flows of a process. The basics of Pinch technology will be presented with a simple example and the presentation of an in deep analysis of a fertilizer complex. (orig.)

  4. Evaluating the effectiveness of joint emission control policies on the reduction of ambient VOCs: Implications from observation during the 2014 APEC summit in suburban Beijing

    Ambient volatile organic compounds (VOCs) at a suburban Beijing site were on-line detected using proton transfer reaction-mass spectrometry (PTR-MS) during autumn of 2014, near the location of the Asia-Pacific Economic Cooperation (APEC) summit. During the APEC summit, the Chinese government enacted strict emission control policies. It was found that VOC concentrations only slightly decreased during the first emission control period (EC I), when control policies were performed in Beijing and 5 cities along the Tai-hang Mountains. However, most of the VOCs (10 out of 12 non-biogenic species) significantly decreased (more than 40%) during the second emission control period (EC II), when control policies were carried out in 16 cities including Beijing, Tianjin, 8 cities of Hebei province and 6 cities of Shandong province. Also the ratio of toluene and benzene decreased during EC II, likely because the emission control policies changed the proportions of different anthropogenic sources. Using the positive matrix factorization (PMF) source apportionment method, five factors are analyzed: (1) vehicle + fuel, (2) solvent, (3) biomass burning, (4) secondary, and (5) background + long-lived. Among them, vehicle + fuel, solvent and biomass burning contribute most of the VOCs concentrations (60%-80%) during the polluted periods and are affected most by emission control policies. During EC II, the reductions of vehicle + fuel, solvent, biomass burning and secondary species were all no less than 50%. Overall, when emission control policies were carried out in many North China Plain (NCP) cities (i.e. EC II), the VOC concentrations of suburban Beijing markedly decreased. This indicates the cross-regional joint-control policies have a large influence on reductions of organic gas species. The findings of this study have vital implications for helping formulate effective emission control policies in China and other countries.

    Schuetz, R.

    1999-01-01

    Benzene has been classified as a toxic compound under the Canadian Environmental Protection Act. This has prompted the Alberta Energy and Utilities Board (AEUB) to introduce specific reporting and monitoring guidelines for the oil and gas industry regarding excessive benzene emissions. Glycol dehydration units have been determined to be the major single source of benzene emissions causing air and soil pollution. DualTank Corp. has designed a condensation and storage tank unit to enhance emission reduction, odour elimination and liquid recovery from dehydration units. Their newly designed combined tank unit consists of a large, uninsulated surface area for cooling, and an excessive internal volume for increased retention time. The first prototype was installed in December 1998 at an Enerplus Resources Site. The system provides excellent benzene emission reduction and the elimination of odours and visual plumes. Effective January 1, 1999, the petroleum and natural gas industry must either clean up excessive emissions voluntarily or face government imposed regulations, facility shutdowns and/or fines. 1 fig

    During the last decade the CO 2 emissions from the residential and tertiary sectors have been rising continuously. This is cause for concern but also an area to be targeted for emission reduction measures in national action plans. This paper proposes a methodological framework, using the Greek building sector (characterized by an aging building stock constructed mostly in the period before 1980) as a case study for the examination of the economic attractiveness of possible measures, which incorporates crucial parameters such as local climate, use of buildings, age of building stock, etc. that affect the energy conservation potential and consequently the economic performance of available measures. Utilizing this framework, the approach is able to classify measures into three categories, namely 'win-win' cases (i.e. where the implementation of emission reduction measures presents a net economic benefit for end-users), measures that require the implementation of appropriate economic support policies in order to make them economically attractive for end-users, and measures that have excessive cost. The results indicate that the emissions reduction potential of 'win-win' cases is significant. They also demonstrate how individual measures can provide significant reductions if carefully targeted economic support policies are applied. Finally, sensitivity analyses performed with respect to the discount rate applied indicate that it has a substantial impact on the economic performance of some measures and consequently on the magnitude of the 'win-win' potential associated to emissions reduction

    Following the announcement of the China's 2020 national target for the reduction of the intensity of carbon dioxide emissions per unit of GDP by 40-45% compared with 2005 levels, Chinese provincial governments prepared to restructure provincial energy policy and plan their contribution to realizing the State reduction target. Focusing on Fujian and Anhui provinces as case studies, this paper reviews two contrasting policies as a means for meeting the national reduction target. That of the coastal province of Fujian proposes to do so largely through the development of nuclear power, whilst the coal-rich province of Anhui proposes to do so through its energy consumption rate rising at a lower rate than that of the rise in GDP. In both cases renewable energy makes up a small proportion of their proposed 2020 energy structures. The conclusion discusses in depth concerns about nuclear power policy, energy efficiency, energy consumption strategy and problems in developing renewable energy. - Research Highlights: → We review two contrasting policies as a means for meeting the national reduction target of carbon emission in two provinces. → Scenario review of energy structure in Fujian and Anhui Provinces to 2020. → We discuss concerns about nuclear power policy, energy efficiency, energy consumption strategy and problems in developing renewable energy.

    This paper described an emissions reduction project conducted by Syncrude Canada and various other companies currently developing and processing oil sands in Alberta. Syncrude's upgrader expansion program included the installation of an ammonia-based wet flue gas desulfurizer (FGD) designed to remove sulphur dioxide (SO{sub 2}) from a coker train. Syncrude is also installing the FGD technology at its existing plants. It is expected that installation of the FGDs will reduced total site emissions of SO{sub 2} by 60 per cent. The fluid cokers are used to crack the long hydrocarbon chain bitumen molecules into shorter molecules. It is expected that the FGD system will also reduce particulate and SO{sub 3} levels. The FGD system was selected after an evaluation of technologies used by the coal-fired power industry. A dry FGD system was selected to operate above the water saturation temperature of the flue gas. Calcium oxide was used as a reagent. Hot gas was quenched in a spray dryer absorber with a slurry of calcium hydroxide. Rotary atomizers were used to developer uniform droplets of slurry. The system's fabric filter was a low ratio reverse gas-cleaned unit. Particulate matter from the gases was deposited on the interior of the filter bags. Clean hot gas was drawn through reverse gas fans into a reverse gas manifold. A timeline of the FGD technology installation process was included. 3 tabs., 28 figs.

  9. Essays on the U.S. biofuel policies: Welfare impacts and the potential for reduction of GHG emission

    This dissertation study investigates the impact of the US biofuel policies related to greenhouse gas (GHG) emission regulation, tax credit and renewable fuel standard (RFS2) mandate over production and consumption of ethanol as well as technical and environmental performance of corn ethanol plants. The study develops analytical models and provides quantitative estimation of the impact of various biofuel policies in each of the three chapters. Chapter 1 of this dissertation examines the tradeoff between achieving the environmental goal of minimizing life cycle GHG emissions and minimizing production costs in recently built dry-grind corn ethanol plants. The results indicate that the average ethanol plant is able to reduce GHG emissions by 36 % relative to the level under cost minimization, but production costs are 22 % higher. To move from least cost to least emissions allocations, ethanol plants would on average produce 25 % more of wet byproduct and 47% less of dry byproduct. Using a multi-output, multi-input partial equilibrium model, Chapter 2 explores the impact of the tax credit and RFS2 mandate policy on market price of ethanol, byproducts, corn, and other factor inputs employed in the production of corn ethanol. In the short-run, without tax credit ethanol plants will not have the incentive to produce the minimum level of ethanol required by RFS2. In the long-run, if ethanol plants to have the incentive to produce the minimum RFS2 mandate without tax credit policy, gasoline price will need to increase by order of 50% or more relative to the 2011 price. Chapter 3 develop meta-regression model to investigate the extent to which statistical heterogeneity among results of multiple studies on soil organic carbon (SOC) sequestration rates can be related to one or more characteristics of the studies in response to conventional tillage (CT) and no-till (NT). Regarding the difference in the rate of SOC sequestration between NT and CT, our results shows that the

    Energy efficiency improvement leads to a reduction in the real cost of energy services per unit, thus bringing about an increase in the demand for energy services. Therefore, the potential energy savings and emission reduction from efficiency improvements might be offset, which is known as “the rebound effect”. This study disaggregates the effect into the direct and indirect effects based on the Slutsky Equation and finds that the rebound effect of Chinese urban households is approximately 22%. It is found that the indirect effect is stronger than the direct effect. These findings prove that the initial goals of the government on energy conservation and emission reduction could not be achieved by improving energy efficiency alone, but need to be supplemented with relevant energy pricing reforms. - Highlights: • This study disaggregates the effect into the direct and indirect effects. • The rebound effect of Chinese urban households is approximately 22%. • The indirect effect is stronger than the direct effect. • Energy pricing reform is needed to mitigate the rebound effect

    This paper aims at providing a rough review of the likely employment effects of European Union policies and measures for CO{sub 2}-emission reductions. This review concentrates mainly on the so-called common and coordinated policies and measures. Furthermore, the analysis is restricted to presenting and systemising existing results on the effects of a CO{sub 2}/energy tax and putting forward a rather qualitative evaluation of the various sectoral policies discussed. The paper is organised as follows. In section 2, the economic impact mechanisms of climate protection policies are discussed. This allows the different arguments brought forward in the debate on the employment effects of CO{sub 2}-reduction policies to be systemised and evaluated. Section 3 presents some of the latest results on the macroeconomic effects of a CO{sub 2}/energy tax. The likely effects of the sectoral policies on the different economic impact categories are discussed in section 4. Conclusions are presented in section 5. (orig.)

    To address the challenge of reducing the greenhouse gas emissions in Canada, the federal and provincial governments are developing strategies and policies to reach that goal. One of the proposed solutions is the establishment of an emission trading system, which it is believed would encourage investment in lower-cost reductions. The Greenhouse Gas Emission Reduction Trading (GERT) pilot was established in 1998 to examine emission trading. It represents the collaborative efforts of government, industry, and non-governmental organizations. It is possible to establish emission reduction trading outside of a regulated environment. Emission reduction is defined as being an action which reduces emissions when compared to what they would have been otherwise. The functioning of GERT was described from the initial application by a buyer/seller to the review process. The assessment of projects is based on mandatory criteria: reductions of emissions must be real, measurable, verifiable and surplus. A section of the presentation was devoted to landfill gas recovery project issues, while another dealt with fuel substitution project issues. Section 5 discussed emission reductions from an off-site source electricity project issues. figs

    A system for improved emissions performance of a power plant generally includes an exhaust gas recirculation system having an exhaust gas compressor disposed downstream from the combustor, a condensation collection system at least partially disposed upstream from the exhaust gas compressor, and a mixing chamber in fluid communication with the exhaust gas compressor and the condensation collection system, where the mixing chamber is in fluid communication with the combustor.

    As a society we are urgently seeking technical solutions to increase energy efficiency, and to reduce green house gas emissions, while at the same time our energy policy is silent on several many issues that are clearly at odds with this. For example, 'drive-thrus' which encourage unnecessary idling, are a staple of an increasing number of businesses, automatic vehicle starter units whose sole function is to increase vehicle idling times are increasing in popularity and becoming standard on some vehicles, and our urban designs increasingly demand ever more personal vehicle use. While technology may provide some solutions, the problem is essentially a sociological one and cannot be solved by technology alone. This paper quantitatively investigates GHG emission reductions possible from relatively simple social changes, and suggests avenues wherein proactive planning will lead to even larger gains. A blind reliance on technology to provide the solutions, while the public is continually presented with new and harmful products is not only presenting engineers with an impossible task, it is doomed to failure. There is a strong need for consistent energy policy, strong government involvement and a concerted and long term effort to educate the public on the implications of their energy choices. This type of policy not only has a direct and immediate impact, it also presents a consistent message that we are all part of the problem and we must all be part of the solution. Technology alone cannot provide a path to sustainability. (author)

  15. The impact of uncertainty on optimal emission policies

    2018-05-01

    We apply a computational framework for specifying and solving sequential decision problems to study the impact of three kinds of uncertainties on optimal emission policies in a stylized sequential emission problem.We find that uncertainties about the implementability of decisions on emission reductions (or increases) have a greater impact on optimal policies than uncertainties about the availability of effective emission reduction technologies and uncertainties about the implications of trespassing critical cumulated emission thresholds. The results show that uncertainties about the implementability of decisions on emission reductions (or increases) call for more precautionary policies. In other words, delaying emission reductions to the point in time when effective technologies will become available is suboptimal when these uncertainties are accounted for rigorously. By contrast, uncertainties about the implications of exceeding critical cumulated emission thresholds tend to make early emission reductions less rewarding.

  17. Scenarios for the use of GHG-reduction instruments - how can policy-instruments as carbon emission trading and tradable green certificates be used simultaneously to reach a common GHG-reduction target?

    According to the agreed burden sharing in the EU, a number of member states have to reduce their emissions of greenhouse gases substantially. To achieve these reductions various policy-instruments - national as well as international - are on hand. Two international instruments are emphasized in this paper: tradable quotas for limiting carbon emissions and tradable green certificates for promoting the deployment of renewable energy technologies. In the analyses of these two instruments two main questions are considered: (1) Will there be any international trade in green certificates, if no GHG-credits are attached to them? (2) Will it make any difference if the EU sets the targets to be achieved by the two instruments or alternatively the individual member countries do? An incentive-analysis in which four scenarios are set up and discussed is performed for the EU member states. The main conclusion is that if no GHG-credits are attached to the green certificates there seems to be limited of no incentives for a permanent international trade in certificates. On the other hand, if GHG-credits are attached to the certificates an efficient international trade will take place regardless of whether the EU or the member countries fix the quotas. Thus, the use of international instruments as tradable green certificates and tradable emissions permits will not lead to an optimal GHG-reduction strategy unless GHG-credits are attached to the certificates.

    Most modelling studies that explore emission mitigation scenarios only look into least-cost emission pathways, induced by a carbon tax. This means that European policies targeting specific – sometimes relatively costly – technologies, such as electric cars and advanced insulation measures, are usually not evaluated as part of cost-optimal scenarios. This study explores an emission mitigation scenario for Europe up to 2050, taking as a starting point specific emission reduction options instead of a carbon tax. The purpose is to identify the potential of each of these policies and identify trade-offs between sectoral policies in achieving emission reduction targets. The reduction options evaluated in this paper together lead to a reduction of 65% of 1990 CO 2 -equivalent emissions by 2050. More bottom-up modelling exercises, like the one presented here, provide a promising starting point to evaluate policy options that are currently considered by policy makers. - Highlights: ► We model the effects of 15 climate change mitigation measures in Europe. ► We assess the greenhouse gas emission reduction potential in different sectors. ► The measures could reduce greenhouse gas emissions by 60% below 1990 levels in 2050. ► The approach allows to explore arguably more relevant climate policy scenarios

    The granting of free emission quotas to selected companies or sectors is currently hotly debated in the climate policy. This article deals with whether such quotas can be used and, if so, how they should be used in order to achieve a more cost-effective environmental policy. It asks on what basis it may be appropriate to grant free emission quotas and discusses what criteria should be used, and if there are better alternatives. It is concluded that free emission quotas are a cost-effective instrument to avoid firm closures and reductions for sufficiently purposeful criteria. Quotas are at best only second best in reducing emigration of firms or production to other countries. However, since more efficient means may be difficult to implement, free emission quotas may be useful in these cases as well

    Environmental innovation has been recognized as an efficient way of addressing environmental problems. However, how environmental innovation may affect carbon emissions in China and whether the effect may differ among various environmental innovation variables remain to be investigated. Therefore, based on the panel data of China’s 30 provinces during 2000–2013, we use a system generalized method of moments (SGMM) technique to estimate the effect of environmental innovation on carbon emissions in China. Also, we evaluate the effect on carbon emission reduction of China’s initial carbon emissions trading (CET) scheme. Empirical results indicate that, most environmental innovation measures in China reduce carbon emissions effectively. Among the various environmental innovation factors, energy efficiency exerts the most evident effect on carbon emissions abatement in China; meanwhile, resources for innovation and knowledge innovation also play prominent roles in this regard. However, the impact of governmental environmental policies on curbing carbon emissions reduction suffers from a lag effect, which mainly occurred during 2006–2013. Finally, despite the short time of operation and incomplete market mechanism, the pilot CET in China has appeared relatively promising with regard to carbon emissions reduction. - Highlights: • The SGMM is used for the effect of environmental innovation on carbon emissions. • Energy efficiency proves the most effective way to reduce China’s carbon emissions. • Innovation resources and knowledge innovation are conducive for carbon reduction. • The governmental environmental policies have lag effect on carbon reduction. • The effect of China’s initial CET on carbon emissions reduction has appeared.

  4. Comparing climate policies to reduce carbon emissions in China

    Currently, China is the largest carbon emitter mainly due to growing consumption of fossil fuels. In 2009, the Chinese government committed itself to reducing domestic carbon emissions per unit of GDP by 40–45% by 2020 compared to 2005 levels. Therefore, it is a top priority for the Chinese government to adopt efficient policy instruments to reduce its carbon intensity. Against this background, this paper develops a general equilibrium model and seeks to provide empirical contributions by comparing the potential impacts of several different policy options to reduce China's carbon emissions. The main findings are as follows. Firstly, these climate policies would affect the structure of economy and contribute to carbon emissions reduction and carbon intensity reduction. Secondly, there would be significant differences in the economic and environmental effects among different climate policies and hence, the government would trade-off among different economic objectives to overcome any potential resistances. Thirdly, there would be considerable differences in the emissions effects of absolute and intensity-based carbon emissions controls, implying that the government might adopt different climate policies for absolute or intensity-based carbon emissions controls. Looking ahead, the government should trade-off among different objectives when designing climate reforms. - Highlights: • We develop a static general equilibrium model to simulate the impacts of climate policies. • We compare the potential impacts of various climate policies in China. • We discuss how to design these policies to make them more effective

    Cement industry is one of the high pollution industries in China. Evaluation of the primary particulate matter (PM) emission status and the reduction potential is not only important for our understanding of the effectiveness of current pollution control measures but also vital for future policy design. In this study, PM emitted from cement producing process in 2014 was calculated using an emission factor method. Three PM emission control scenarios were set up considering source control, process management and end-of-pipe treatment, and the PM emission reduction by 2020 under the three scenarios was predicted, respectively. In 2014, the primary PM emission from cement industry was 1.95 million tons. By 2020, the productions of cement and clinker were expected to increase by 12% and 7%, respectively, and the PM emission would increase by about 10%. By implementation of GB4915-2013 and comprehensive control of fugitive PM emission, the PM emission would probably be reduced by 34%. Another 7% decrease would be expected from source control. The second scenario can be considered as an assessment of the effectiveness of the revised emission standard, and this research can be used as a technical support to the environmental management authorities to make relevant policies.

    Ships, with their high consumption of fossil fuels to power their engines, are significant air polluters. Emission reduction methods therefore need to be implemented and the aim of this paper is to assess the advantages and disadvantages of each emissions reduction method. Benefits of the different methods are compared, with their disadvantages and requirements, to determine the applicability of such solutions. The methods studied herein are direct water injection, humid air motor, sea water scrubbing, diesel particulate filter, selected catalytic reduction, design of engine components, exhaust gas recirculation and engine replacement. Results of the study showed that the usefulness of each emissions reduction method depends on the particular case and that an evaluation should be carried out for each ship. This study pointed out that methods to reduce ship emissions are available but that their applicability depends on each case.

    The International Maritime Organization (IMO) has recently proposed several operational and technical measures to improve shipping efficiency and reduce the greenhouse gases (GHG) emissions. The abatement potentials estimated for these measures have been further used by many organizations to project future GHG emission reductions and plot Marginal Abatement Cost Curves (MACC). However, the abatement potentials estimated for many of these measures can be highly uncertain as many of these measures are new, with limited sea trial information. Furthermore, the abatements obtained are highly dependent on ocean conditions, trading routes and sailing patterns. When the estimated abatement potentials are used for projections, these ‘input’ uncertainties are often not clearly displayed or accounted for, which can lead to overly optimistic or pessimistic outlooks. In this paper, we propose a methodology to systematically quantify and account for these input uncertainties on the overall abatement potential forecasts. We further propose improvements to MACCs to better reflect the uncertainties in marginal abatement costs and total emissions. This approach provides a fuller and more accurate picture of abatement forecasts and potential reductions achievable, and will be useful to policy makers and decision makers in the shipping industry to better assess the cost effective measures for CO 2 emission reduction. - Highlights: • We propose a systematic method to quantify uncertainty in emission reduction. • Marginal abatement cost curves are improved to better reflect the uncertainties. • Percentage reduction probability is given to determine emission reduction target. • The methodology is applied to a case study on maritime shipping.

  8. Policy packages to achieve demand reduction

    In many sectors and many countries, energy demand is still increasing, despite decades of policies to reduce demand. Controlling climate change is becoming more urgent, so there is a need to devise policies that will, virtually, guarantee demand reduction. This has to come from policy, at least in the UK, as the conditions do not exist, yet, when the consumers will 'pull' the market for energy efficiency or the manufacturers will use technological development to 'push' it. That virtuous circle has to be created by a mixture of consumer education and restrictions on manufacturers (for instance, permission to manufacture). The wider policy options include higher prices for energy and stronger product policies. An assessment of the effectiveness of different policy packages indicates some guiding principles, for instance that improved product policy must precede higher prices, otherwise consumers are unable to react effectively to price rises. The evidence will be assessed about the ways in which national and EU policies can either reinforce, duplicate or undermine each other. Another area of examination will be timescales: what is the time lag between the implementation of a policy (whether prices or product based) and the level of maximum reductions. In addition, the emphasis given to factors such as equity, raising investment funds and speed of delivery also influence policy design and the extent to which absolute carbon reductions can be expected

    States have historically been the primary drivers of climate change policy in the US, particularly with regard to emissions from power plants. States have implemented policies designed either to directly curb greenhouse gas (GHG) emissions from power plants, or to encourage energy efficiency and renewable energy growth. With the federal government withdrawing from the global climate agreement, understanding which state-level policies have successfully mitigated power-plant emissions is urgent. Past research has assessed policy effectiveness using data for periods before the adoption of many policies. We assess 17 policies using the latest data on state-level power-sector CO2 emissions. We find that policies with mandatory compliance are reducing power-plant emissions, while voluntary policies are not. Electric decoupling, mandatory GHG registry/reporting and public benefit funds are associated with the largest reduction in emissions. Mandatory GHG registry/reporting and public benefit funds are also associated with a large reduction in emissions intensity.

  10. Emissions reductions from expanding state-level renewable portfolio standards.

    2015-05-05

    In the United States, state-level Renewable Portfolio Standards (RPS) have served as key drivers for the development of new renewable energy. This research presents a method to evaluate emissions reductions and costs attributable to new or expanded RPS programs by integrating a comprehensive economic dispatch model and a renewable project selection model. The latter model minimizes incremental RPS costs, accounting for renewable power purchase agreements (PPAs), displaced generation and capacity costs, and net changes to a state's imports and exports. We test this method on potential expansions to Michigan's RPS, evaluating target renewable penetrations of 10% (business as usual or BAU), 20%, 25%, and 40%, with varying times to completion. Relative to the BAU case, these expanded RPS policies reduce the CO2 intensity of generation by 13%, 18%, and 33% by 2035, respectively. SO2 emissions intensity decreased by 13%, 20%, and 34% for each of the three scenarios, while NOx reductions totaled 12%, 17%, and 31%, relative to the BAU case. For CO2 and NOx, absolute reductions in emissions intensity were not as large due to an increasing trend in emissions intensity in the BAU case driven by load growth. Over the study period (2015 to 2035), the absolute CO2 emissions intensity increased by 1% in the 20% RPS case and decreased by 6% and 22% for the 25% and 40% cases, respectively. Between 26% and 31% of the CO2, SO2, and NOx emissions reductions attributable to the expanded RPS occur in neighboring states, underscoring the challenges quantifying local emissions reductions from state-level energy policies with an interconnected grid. Without federal subsidies, the cost of CO2 mitigation using an RPS in Michigan is between $28 and $34/t CO2 when RPS targets are met. The optimal renewable build plan is sensitive to the capacity credit for solar but insensitive to the value for wind power.

    A panel was formed to assess the feasibility and cost of energy-related greenhouse gas (GHG) emissions reduction in Canada. The panel studies focused on the potential for increased energy efficiency and fuel switching and their effect in reducing CO 2 emissions by reviewing the extensive literature available on those topics and assessing their conclusions. Economically feasible energy savings are estimated mostly in the range of 20-40% savings by the year 2010 relative to a reference-case projection, with a median of 23%. The panel concluded that achieving the identified economic potential for increased energy efficiency by 2010 will depend on development of additional demand-side management or energy efficiency programs that go well beyond current policies and programs. Fuel switching will play a much smaller role in stabilizing energy-related CO 2 emissions than improved energy efficiency. Technology substitution and broader structural change would enable Canada to achieve significant reductions in CO 2 emissions; however, more research is needed on achieving emission reductions that would approach the levels estimated to be required globally for stabilization of atmospheric CO 2 concentrations. Achieving such emissions reductions would likely require a combination of significant improvements in energy efficiency, major changes in energy sources, and substantial changes in economic activity and life styles, relative to that projected in most reference-case forecasts. 5 refs., 1 fig., 10 tabs

    China's carbon dioxide (CO 2 ) emission ranks highest in the world. China is committed to reduce its CO 2 emission by 40% to 45% from the 2005 levels by 2020. To fulfill the target, China's CO 2 emission reduction must exceed 6995 million tons. Energy consumption and CO 2 emission of China's urban district heating (UDH) are increasing. The current policy implemented to improve UDH focuses on replacing coal with natural gas to reduce energy consumption and CO 2 emission to some extent. This paper proposes that heat pump heating (HPH) could serve as a replacement for UDH to help realize energy-saving and emission-reduction goals to a greater extent. The paper also analyzes the impact of this replacement on the heating and power generation sectors. The results show that replacing coal-based UDH with HPH decreases energy consumption and CO 2 emission by 43% in the heating sector. In the power generation sector, the efficiency of power generation at the valley electricity time increases by 0.512%, and the ratio of peak–valley difference decreases by 16.5%. The decreases in CO 2 emission from the heating and power generation sectors cumulatively account for 5.55% of China's total CO 2 emission reduction target in 2020. - Highlights: ► Replacing urban district heating with heat pump heating. ► Impact of heat pump heating on heating and power generation sectors. ► Potential of energy saving and emission reduction for heat pump heating. ► China should adjust current urban heating strategy

    Further action is needed that goes far beyond what has been agreed so far under the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol to 'prevent dangerous anthropogenic interference with the climate system', the ultimate objective of the UNFCCC. It is out of question that developed countries (Annex I countries) will have to take a leading role. They will have to commit to substantial emission reductions and financing commitments due to their historical responsibility and their financial capability. However, the stabilisation of the climate system will require global emissions to peak within the next decade and decline well below half of current levels by the middle of the century. It is hence a global issue and, thus, depends on the participation of as many countries as possible. This report provides a comparative analysis of greenhouse gas (GHG) emissions, including their national climate plans, of the major emitting developing countries Brazil, China, India, Mexico, South Africa and South Korea. It includes an overview of emissions and economic development, existing national climate change strategies, uses a consistent methodology for estimating emission reduction potential, costs of mitigation options, provides an estimate of the reductions to be achieved through the national climate plans and finally provides a comparison of the results to the allocation of emission rights according to different global effort-sharing approaches. In addition, the report discusses possible nationally appropriate mitigation actions (NAMAs) the six countries could take based on the analysis of mitigation options. This report is an output of the project 'Proposals for quantifying emission reduction contributions by emerging economies' by Ecofys and the Wuppertal Institute for the Federal Environment Agency in Dessau. It builds upon earlier joint work ''Proposals for contributions of emerging economies to the climate

  17. Carbon emissions and an equitable emission reduction criterion

    International Nuclear Information System (INIS)

    Golomb, Dan

    1999-01-01

    In 1995 the world-wide carbon emissions reached 5.8 billion metric tonnes per year (GTC/y). The Kyoto protocol calls for a reduction of carbon emissions from the developed countries (Annex I countries) of 6-8% below 1990 levels on the average, and unspecified commitments for the less developed (non-Annex I) countries. It is doubtful that the Kyoto agreement will be ratified by some parliaments, especially the USA Congress. Furthermore, it is shown that if the non-Annex I countries will not curtail their carbon emissions drastically, the global emissions will soar to huge levels by the middle of the next century. An equitable emission criterion is proposed which may lead to a sustainable rate of growth of carbon emissions, and be acceptable to all countries of the world. The criterion links the rate of growth of carbon emissions to the rate of growth of the Gross Domestic Product (GDP). A target criterion is proposed R = 0.15 KgC/SGDP, which is the current average for western European countries and Japan. This allows for both the growth of the GDP and carbon emissions. However, to reach the target in a reasonable time, the countries for which R≤ 0.3 would be allowed a carbon emission growth rate of 1%./y, and countries for which R≥ 0.3, 0.75%/y. It is shown that by 2050 the world-wide carbon emissions would reach about 10 GTC/y, which is about 3 times less than the Kyoto agreement would allow. (Author)

    Transport represents the sector with the fastest growing greenhouse gas emissions around the world. The main global objective is to reduce energy usage and associated greenhouse gas emissions from the transportation sector. For this study it was analyzed the road transportation system from Brasov Metropolitan area. The study was made for the transportation route that connects Ghimbav city to the main surrounding objectives. In this study ware considered four optimization measures: vehicle fleet renewal; building the detour belt for the city; road increasing the average travel speed; making bicycle lanes; and implementing an urban public transport system for Ghimbav. For each measure it was used a mathematical model to calculate the energy consumption and carbon emissions from the road transportation sector. After all four measures was analyzed is calculated the general energy consumption and CO2 reduction if this are applied from year 2017 to 2020.

    Full text: The development of climate change policy in Australia is at an important stage in its evolution. Australia, as a ratifying nation of 1992 United Nations Framework Convention on Climate Change, has obligations as a party including development and implementation of national policy. In 2004, Australia announced a Climate Change Strategy updating the 1997 National Greenhouse Strategy which set out the framework for a coordinated and collaborative approach by all levels of government in Australia. The 2004 Climate Change Strategy is directed toward the achievement of three overarching goals: 'international engagement - pursuing an effective global response to climate change', 'emissions management...', and 'providing the foundations for Australia's climate change response...'. Despite not ratifying the Kyoto Protocol, Australia has committed to informally meet its 108% Kyoto Protocol target by taking on the role of an 'as if Party. Development and implementation a broad range of greenhouse gas emission reduction strategies, policies and programs, at the Commonwealth, state and territory, and local government levels, has occurred. Notably, the recent 2007-08 Australian Government Budget brought its total commitment to its climate change strategy to A$2.8 billion. Combined government action and industry investment in climate change mitigation via implementation of greenhouse gas emission reduction schemes are thus well underway. The Commonwealth's programs for greenhouse emission reduction are significant, and in particular, the Greenhouse Challenge Plus program certainly is a key industry motivator. Both state and local government actions have been drivers in policy development, supporting reduction of greenhouse emissions. Several states have implemented their own climate change strategies and the states have been proactive in their interest in emissions trading. Local councils' roles, in particular, have been and will increase in significance in the future

    The demand for transport services is expected to rise, causing the CO 2 emissions level to increase as well. In Malaysia, the transportation sector accounts for 28% of total CO 2 emissions, of which 85% comes from road transport. By 2020, Malaysia is targeting a reduction in CO 2 emissions intensity by up to 40% and in this effort the role of road transport is paramount. This paper attempts to investigate effective policy options that can assist Malaysia in reducing the CO 2 emissions level. An Optimisation model is developed to estimate the potential CO 2 emissions mitigation strategies for road transport by minimising the CO 2 emissions under the constraint of fuel cost and demand travel. Several mitigation strategies have been applied to analyse the effect of CO 2 emissions reduction potential. The results demonstrate that removal of fuel price subsidies can result in reductions of up to 652 ktonnes of fuel consumption and CO 2 emissions can be decreased by 6.55%, which would enable Malaysia to hit its target by 2020. CO 2 emissions can be reduced significantly, up to 20%, by employing a combination of mitigation policies in Malaysia. This suggests that appropriate mitigation policies can assist the country in its quest to achieve the CO 2 emissions reduction target. - Highlights: • An optimisation model for CO 2 emissions reduction in Malaysia's road transport is formulated. • Sensible policy options to achieve the CO 2 emissions reduction target are provided. • Increase in fuel price has induced shift towards fuel efficient vehicles. • The CO 2 emissions can be reduced up to 5.7 MtCO 2 with combination of mitigation policies.

    According to the agreed burden sharing within the European Union the overall EU emission reduction target as agreed by in the Kyoto protocol is converted into national greenhouse gas reduction-targets for each of the member states. In parallel with national emission reduction initiatives common EU policies for emission reductions are considered. Currently discussed is the introduction of a market for tradable permits for CO 2 -emissions to achieve emission reductions within the power industry and other energy intensive industries. In parallel with this markets for green certificates to deploy renewable energy technologies seem to be appearing in a number of countries, among these Denmark, Italy, Sweden, Belgium (Flanders), England and Australia. Although these national initiatives for a green certificate market are fairly different, they could be a starting point for establishing a common EU certificate market. But interactions between national targets for greenhouse gas emissions and these international instruments for emission reduction are not a trivial matter, especially not seen in relation to the possible contributions of these instruments in achieving national GHG-reduction targets. The paper is split into three parts all taking a liberalised power market as starting point: The first part discusses the consequences of a general deployment of renewable energy technologies, using planning initiatives or national promotion schemes (feed-in tariffs). In the second part an international green certificate market is introduced into the liberalised power market context, substituting other national promotion schemes. Finally, in the third part a combination of an international green certificate market (TGC) and an international emission-trading scheme for CO 2 is analysed within the liberalised international power market set-up. The main conclusion is that neither the use of national renewable support schemes nor the introduction of a TGC-market into a liberalised

    GHG (Increasing greenhouse gas) emissions in China imposes enormous pressure on China's government and society. The increasing GHG trend is primarily driven by the fast expansion of high energy-intensive sectors including the chemical industry. This study investigates energy consumption and CO 2 emissions in the processes of chemical production in China through calculating the amounts of CO 2 emissions and estimating the reduction potential in the near future. The research is based on a two-level perspective which treats the entire industry as Level one and six key sub-sectors as Level two, including coal-based ammonia, calcium carbide, caustic soda, coal-based methanol, sodium carbonate, and yellow phosphorus. These two levels are used in order to address the complexity caused by the fact that there are more than 40 thousand chemical products in this industry and the performance levels of the technologies employed are extremely uneven. Three scenarios with different technological improvements are defined to estimate the emissions of the six sub-sectors and analyze the implied reduction potential in the near future. The results highlight the pivotal role that regulation and policy administration could play in controlling the CO 2 emissions by promoting average technology performances in this industry.

    In this paper the LEAP, TIAM-ECN, and GCAM models were applied to evaluate the impact of a variety of climate change control policies (including carbon pricing and emission constraints relative to a base year) on primary energy consumption, final energy consumption, electricity sector development, and CO_2 emission savings of the energy sector in Argentina over the 2010–2050 period. The LEAP model results indicate that if Argentina fully implements the most feasible mitigation measures currently under consideration by official bodies and key academic institutions on energy supply and demand, such as the ProBiomass program, a cumulative incremental economic cost of 22.8 billion US$(2005) to 2050 is expected, resulting in a 16% reduction in GHG emissions compared to a business-as-usual scenario. These measures also bring economic co-benefits, such as a reduction of energy imports improving the balance of trade. A Low CO_2 price scenario in LEAP results in the replacement of coal by nuclear and wind energy in electricity expansion. A High CO_2 price leverages additional investments in hydropower. By way of cross-model comparison with the TIAM-ECN and GCAM global integrated assessment models, significant variation in projected emissions reductions in the carbon price scenarios was observed, which illustrates the inherent uncertainties associated with such long-term projections. These models predict approximately 37% and 94% reductions under the High CO_2 price scenario, respectively. By comparison, the LEAP model, using an approach based on the assessment of a limited set of mitigation options, predicts an 11.3% reduction. The main reasons for this difference include varying assumptions about technology cost and availability, CO_2 storage capacity, and the ability to import bioenergy. An emission cap scenario (2050 emissions 20% lower than 2010 emissions) is feasible by including such measures as CCS and Bio CCS, but at a significant cost. In terms of technology

    Nitrogen oxides develop mainly in the combustion of fossil fuels based on three mechanisms: process-dependent thermal NO; prompt NO as well as fuel-dependent NO. The reaction either takes places in the area of the root of the flame or with the combustion gases. A main effect on the amount of developing nitrogen oxides have the fuel, the burner design as well as the heat generator. In the last years considerable emission reductions were attained mainly by design changes of the burner, e.g. gas burners with internal circulation, burners with external exhaust gas recirculation, burners with internal recirculation.

    Due to human activities, concentrations of the greenhouse gases increase in the atmosphere much quicker than they naturally would. Today it is clear that climate change is the result of human activities. With the purpose of preventing, reducing and mitigating of climate change, the EU, whose member is also Slovenia, set ambitious goals. In order to keep rise of the global atmosphere temperature below 2 degrees of C, the European Council set an objective of reducing greenhouse gas emissions by 80 - 95 % by 2050 compared to 1990. It is important that every single individual is included in achieving of these goals. Certainly, the most important role is assumed by individual sectors especially Public Electricity and Heat Production sector as one of the greatest emitters of the greenhouse gases. As a possible solution of radical reduction of the greenhouse gases emission from mentioned sector Carbon Capture and Storage (CCS) technology is implemented. In the article the range of CO 2 reduction possibilities, technology demands and environmental side effects of CCS technology are described. Evaluation of CCS implementation possibilities in Slovenia is also included.(author)

    After the climate change negotiation reaches an agreement in COP7, the next main issue to be addressed is the way of involvement of developing countries in emission abatement commitments and the development of domestic policies and measures to achieve GHG emission reduction target. Many Annex I countries have developed and implemented policies and measures to achieve its quantified GHG emission reduction target. The purpose of this paper is to propose a portfolio of policies and measures, that is, which policies and measures Korea will have to take in preparing future commitment for GHG emission reduction as well as in strengthening mitigation of climate change. Various policies and measures can be used, such as regulations, economic instruments, and covenants, etc., but it is desirable to implement them in some portfolio, taking advantage of their characteristics. Among the possible policies and measures, this study found that economic instruments such as carbon tax and domestic emissions trading have attracted considerable interest recently due to their cost effectiveness. This study also found that, in practice, many developed countries have used these policy instruments in achieving their quantified GHG emission reduction target. In order to develop a portfolio of policies and measures, the comprehension of the features of each policy and measure and the synergetic reconciliation with other objectives than climate change is important.

    Full Text Available We focus on the joint production planning of complex supply chains facing stochastic demands and being constrained by carbon emission reduction policies. We pick two typical carbon emission reduction policies to research how emission regulation influences the profit and carbon footprint of a typical supply chain. We use the input-output model to capture the interrelated demand link between an arbitrary pair of two nodes in scenarios without or with carbon emission constraints. We design optimization algorithm to obtain joint optimal production quantities combination for maximizing overall profit under regulatory policies, respectively. Furthermore, numerical studies by featuring exponentially distributed demand compare systemwide performances in various scenarios. We build the “carbon emission elasticity of profit (CEEP” index as a metric to evaluate the impact of regulatory policies on both chainwide emissions and profit. Our results manifest that by facilitating the mandatory emission cap in proper installation within the network one can balance well effective emission reduction and associated acceptable profit loss. The outcome that CEEP index when implementing Carbon emission tax is elastic implies that the scale of profit loss is greater than that of emission reduction, which shows that this policy is less effective than mandatory cap from industry standpoint at least.

    Air pollution and its impacts over the Northeast Asia are very severe because of the massive pollutant emissions and high population. Korea has been trying to improve air quality with the enhanced environmental legislation. The air quality over Korea, however, does not entirely dependent on its local emissions. Transboundary air pollution from China highly affects Korean atmosphere. The purpose of this research is to understand role of local and transbounday efforts to improve air quality changes over Korea. In this research, we have tried to set up the multiple emission scenario pathways for Korea and China using IIASA's GAINS (Greenhouse gas - Air pollution Interactions aNd Synergies) modeling framework. More up-to-date growth factors and control policy packets were made using regional socio-economic data and control policy information from local governments and international statistics. Four major scenario pathways, 1) Base (Baseline: current legislation), 2) OTB/OTB(On the book/On the way : existing control measure/planed control measure), 3) BOTW_GHG(Beyond on the way : OTW with GHG reduction plan), 4) BOTW_NH3 (OTW with additional NH3 reduction measure) were developed to represent air quality improvement pathways in consideration of both Korean and Chinese efforts. Strict ambient PM2.5 standards from Seoul metropolitan Air quality Improvement Plan(SAIP) seems too enthusiastic without linking air quality control efforts of China. Step-by-step emission controls and following air quality, control cost, health impact from each scenario will be presented at the conference. This subject is supported by Korea Ministry of Environment as "Climate Change Correspondence Program".

    Since the mid-eighties total annual acidifying emissions have started to decline in West Germany. There was considerable impact on this positive trend in air pollution by the control of SO 2 and NO x emissions from large boilers, which were reduced by more than 80%. Corresponding control programmes have been established for other groups of sources as well as other pollutants and - with unification - for East Germany. The driving force behind this development was and still is first of all the legal principle of anticipatory action or precaution which means in practical terms 'emission minimization'. This cornerstone of German clean air legislation is the most powerful components of Germany's 'acidification policy', as it requires policy-makers to draw up new or review existing regulations for emission reduction based on requirements according to the state of the art and forces operators to apply the most modern ways and means of operation. This paper describes the system used in Germany to deal with air pollution, the emission minimization strategy, and the actions against acidifying emissions based thereon. In addition, an outlook on what might be necessary to cope with the challenges of a sustainable development concerning acidification is given. 1 ref., 1 fig., 2 tabs

    The effect of adding hydrogen to methane as a fuel for spark ignited engines has been extensively investigated. Both the possibility of adding a limited amount of hydrogen as well as equal amounts of hydrogen and carbon dioxide to natural gas has been investigated. A 10 vol% addition of hydrogen to the natural gas caused a reduction in UHC of approximately 40%, and an increase in efficiency of approximately three percentage points at the test engine. It is unknown if the gain is representative for large engines. Similar results for UHC reduction and efficiency were obtained for combined hydrogen and carbon dioxide addition. The carbon dioxide was added by exhaust gas recirculation. However, the price of hydrogen, makes this idea uneconomical even when carbon dioxide is readily available through recirculation of engine exhaust. Adiabatic prereforming may be used to convert natural gas into methane, hydrogen and carbon dioxide in order to generate hydrogen and at the same time increase the methane number. The process has been found to be competitive with adding of hydrogen but it is still not economical. The effect of NO/NO{sub 2} on methane oxidation has been studied both theoretically and experimentally. A detailed kinetic modelling study of the UHC conversion dependency of exhaust gas parameters is reported and the project has contributed to the theoretical understanding of the oxidation chemistry. Both NO and NH{sub 3} addition to the engine inlet was used to increase the NO{sub x} level, and the general trend was a decrease in UHC as the NO{sub x} level increased, both in cylinger, manifold and rector. From the data it is concluded that NO and NH{sub 3} addition have identical effects. The results show a 15-35% decrease in manifold UHC. However, the increased emissions of NO{sub x} and CO associated with this process must be realised. Field tests show a 28% UHC reduction without an increase in CO emission. The UHC oxidation in the exhaust reactor has been tested

    Using the most recent energy and other statistical data, we have estimated the annual trends in China's greenhouse gas emissions for the period 1990 to 2000. The authors of this Policy Forum calculate that CO2 emissions declined by 7.3% between 1996 and 2000, while CH4 emissions declined by 2.2% between 1997 and 2000. These reductions were due to a combination of energy reforms, economic restructuring, forestry policies, and economic slowdown. The effects of these emission changes on global mean temperatures are estimated and compared with the effects of concurrent changes in two aerosol species, sulfate and black carbon.

  13. Emission taxes versus other environmental policies

    1997-06-01

    In most countries, various forms of quotas and direct regulation play a more important role in environmental policy than environmental taxes. This report discusses four arguments often given against emission taxes. Three of the arguments, which are related to information asymmetries and non-convexities, are valid arguments in the sense that they point at complications which make the use of environmental taxes less straightforward than what elementary textbooks would suggest. The fourth argument is related to the employment effects of different types of environmental policies in economies with unemployment. This is perhaps the argument most often used by politicians against environmental taxes. The analysis did not justify this type of argument. On the contrary: In the model used, employment is higher with environmental taxes than with non revenue-raising environmental policies. 18 refs., 6 figs.

  15. Frameworks for pricing greenhouse gas emissions and the policy objectives they promote

    Higgins, Paul A.T.

    2013-01-01

    Four cost-effective frameworks for pricing greenhouse gas emissions currently receive widespread attention: cap-and-trade, emission fees, and hybrid cap-and-trade approaches that include upper or lower limits on permit prices (price ceilings or floors). This paper develops a fifth framework that uses an emission fee with an upper limit on the quantity of emissions—a quantity ceiling—and compares the impact of each framework on emission prices and quantities. Cap-and-trade with a price ceiling minimizes price increases for emitting activities in all cases whereas an emission fee with a quantity ceiling maximizes emissions reductions. Thus, the choice of framework influences policy outcomes because each framework is more or less suited to particular policy goals. Whether pursuing one potential policy goal serves society's interests best depends on the eventual consequences of climate damage and emissions pricing, which are uncertain when policy choices are made. Policy updating over time may reduce but likely cannot entirely eliminate the differences in outcome that arise due to framework choice. Therefore, the “best” framework for emissions pricing depends on subjective preferences regarding the relative importance of different policy objectives, most notably whether one is more risk averse to climate damages or emissions price increases. - Highlights: • This article develops and examines a carbon tax that includes a quantity constraint on emissions. • This approach maximizes climate protection in all cases, unlike existing policy alternatives. • This promotes rapid reductions in emissions if mitigation is easy without risk to long term targets. • This analysis reveals that different policy frameworks promote different policy goals. • The analysis helps round out ongoing policy discussions over how to deal with climate change

    Highlights: • Potential to reduce urban passenger transport is projected between 2010 and 2040. • Four scenarios reflecting different policy mixes are considered. • The potential for energy conservation and emission reductions are obtained. • Vehicle population regulation is most effective in energy saving and reducing overall GHG. • Emission standards are the most effective measure to reduce pollutant emissions. - Abstract: With rapid growth of the vehicle population, urban passenger transport in China is largely responsible for increases in energy consumption, greenhouse gas (GHG) emissions, and also atmospheric pollutants (NO x , CO, HC, PM). In this paper, we first develop an urban passenger transport energy saving and emission reduction potential evaluation model using the “Long Range Energy Alternatives Planning (LEAP)” tool; and then take Tianjin city as an empirical case to evaluate the reduction potential of final energy consumption, GHG emissions and pollutants emissions of Tianjin’s urban passenger transport sector between 2010 and 2040 under four scenarios, i.e. BAU (business as usual) scenario, PP (the 12th five-year plan policy) scenario, CP (comprehensive policy) scenario and HP (hybrid policy of PP and CP) scenario. The results show that due to the public transport promotion, energy consumption and CO 2 emissions in 2040 can be reduced by 22% and 22.6% in the PP scenario, compared to BAU. The largest reductions in energy consumption, CO 2 and atmospheric pollutants emissions can be achieved under CP scenario, in which vehicle population regulation is the most effective to be implemented. Emissions standard regulation is the most effective measure to reduce atmospheric pollutant emissions in all the scenarios and green energy promotion is especially effective to reduce NO x and PM

    Future emissions under the SRES scenarios are described as examples of no-climate-policy scenarios. The production of policy scenarios is guided by Article 2 of the UN Framework Convention on Climate Change, which requires stabilization of greenhouse-gas concentrations. It is suggested that the choice of stabilization targets should be governed by the need to avoid dangerous interference with the climate system, while the choice of the pathway towards a given target should be determined by some form of cost-benefit analysis. The WRE (Wigley, Richels and Edmonds) concentration profiles are given as examples of stabilization pathways, and an alternative 'overshoot' pathway is introduced. Probabilistic projections (as probability density functions - pdfs) for global-mean temperature under the SRES scenarios are given. The relative importance of different sources of uncertainty is determined by removing individual sources of uncertainty and examining the change in the output temperature pdf. Emissions and climate sensitivity uncertainties dominate, while carbon cycle, aerosol forcing and ocean mixing uncertainties are shown to be small. It is shown that large uncertainties remain even if the emissions are prescribed. Uncertainties in regional climate change are defined by comparing normalized changes (i.e., changes per 1C global-mean warming) across multiple models and using the inter-model standard deviation as an uncertainty metric. Global-mean temperature projections for the policy case are given using the WRE profiles. Different stabilization targets are considered, and the overshoot case for 550ppm stabilization is used to quantify the effects of pathway differences. It is shown that large emissions reductions (from the no-policy to the policy case) will lead to only relatively small reductions in warming over the next 100 years

    Target groups as well as the government are under the spell of economic instruments as part of environmental policy. Under this heading fall (regulatory) taxes and tradeable emission permits (VER). Of the two, VER, particularly, receive a lot of attention. From the target groups, because the flexibility of VER means working cost-effectively, which could lead to cost savings. From the government, because it can have more faith in the viability of emission ceilings, and has less need to pass detailed legislation. The latter conforms nicely to the philosophy `government at arm`s length`. The Ministry of Environment has had a study made on the feasibility of VER in the context of the acidification abatement policy in the Netherlands. The development and implementation of policy concerning acidification abatement is at an advanced stage, with deposition targets already set for 2000 and 2010 (2400 and 1400 acid equivalents/ha/year, respectively, averaged for afforested areas). From these, also emission reduction targets per target group are deduced, which can be used in a VER system. The main starting point of the study was to gain more insight into the practical aspects of VER. One important question is what form a VER system for the Netherlands should have to take. Also, an investigation was made into the activities which are necessary to introduce a VER system as well as the time, manpower and money these activities entail

The development and implementation of policy concerning acidification abatement is at an advanced stage, with deposition targets already set for 2000 and 2010 (2400 and 1400 acid equivalents/ha/year, respectively, averaged for afforested areas). From these, also emission reduction targets per target group are deduced, which can be used in a VER system. The main starting point of the study was to gain more insight into the practical aspects of VER. One important question is what form a VER system for the Netherlands should have to take. Also, an investigation was made into the activities which are necessary to introduce a VER system as well as the time, manpower and money these activities entail

    In this paper, we explore GHG emission scenarios up to 2050 in Asia and the world as part of the Asian Modeling Exercise and assess technology options for meeting a 2.6 W/m 2 radiative forcing target using AIM/Enduse[Global] and AIM/Impact[Policy]. Global GHG emissions in 2050 are required to be reduced by 72% relative to a reference scenario, which corresponds to a 57% reduction from the 2005 level, in order to meet the above target. Energy intensity improvement contributes a lot to curbing CO 2 emission in the short-term. Meanwhile, carbon intensity reduction and CO 2 capture play a large role for further emission reduction in the mid to long-term. The top five key technologies in terms of reduction amount are CCS, solar power generation, wind power generation, biomass power generation and biofuel, which, in total, account for about 60% of global GHG emissions reduction in 2050. We implement additional model runs, each of which enforced limited availability of one of the key technology. The result shows that the 2.6 W/m 2 target up to 2050 is achievable even if availability of any one of the key technologies is limited to half the level achieved in the default simulation. However, if the use of CCS or biomass is limited, the cumulative GHG abatement cost until 2050 increases considerably. Therefore CCS and biomass have a vital role in curbing costs to achieve significant emission reductions. - Highlights: ► We explore GHG emission scenarios up to 2050 in Asia and the world. ► Significant GHG emission reduction is required to limit radiative forcing at low level. ► We assess technology options for achieving significant GHG emission reduction. ► CCS, solar power, wind power, and biomass are the key technologies for reduction. ► Especially, CCS and biomass play a vital role in curbing costs to achieve significant emission reductions.

  3. Technologies and policies for "hard to scrub" emissions sources

    The science of climate change yields harsh math regarding atmospheric accumulations of GHGs. The world is far from target trajectories for 2C or 1.5C, and the global carbon budget is severe. To achieve those targets requires two things. First, we must field technologies that reduce emissions from the "hard to scrub" parts of the US and global economies, such as heavy industry (cement and steel), aviation, ocean shipping, and household cooking and heating. Second, we will likely need negative emissions pathways for those sources that prove extremely difficult to remove or reduce - the climate equivalent of adding revenue to one's budget. Such pathways may well need to convert GHG emissions (especially CO2 and methane) into useful products with minimal infrastructure builds. Dramatic advances in advanced manufacturing, 3D printing, simulation, modeling, and data analytics have made possible solutions which were previously unthinkable or impossible. This include "bespoke reactors", which can simultaneously perform separations and conversions; low-cost modular chemical systems of any scale; biologically inspired or biologically mediated energy services; direct air carbon-capture systems; and electrochemical pathways for emissions reduction and conversion. However, these approaches are unlikely to be fielded without policy actions or reforms that support such systems in competitive global energy markets. Such policy measures do NOT require a carbon price. Rather, they could include individual or combined measures such as emission or performance standards, financial incentives (like tax credits or low-cost access to capital), border adjustable tariffs, creation of CO2 utilities, ands public good surcharges. Innovation in both technical and policy arenas are needed to achieve the goals of the Paris agreement signatories, and these innovations can be simultaneously configured to deliver substantive greenhouse gas mitigation.

  4. Are renewables portfolio standards cost-effective emission abatement policy?

    Science.gov (United States)

    Dobesova, Katerina; Apt, Jay; Lave, Lester B

    2005-11-15

    Renewables portfolio standards (RPS) could be an important policy instrument for 3P and 4P control. We examine the costs of renewable power, accounting for the federal production tax credit, the market value of a renewable credit, and the value of producing electricity without emissions of SO2, NOx, mercury, and CO2. We focus on Texas, which has a large RPS and is the largest U.S. electricity producer and one of the largest emitters of pollutants and CO2. We estimate the private and social costs of wind generation in an RPS compared with the current cost of fossil generation, accounting for the pollution and CO2 emissions. We find that society paid about 5.7 cent/kWh more for wind power, counting the additional generation, transmission, intermittency, and other costs. The higher cost includes credits amounting to 1.1 cent/kWh in reduced SO2, NOx, and Hg emissions. These pollution reductions and lower CO2 emissions could be attained at about the same cost using pulverized coal (PC) or natural gas combined cycle (NGCC) plants with carbon capture and sequestration (CCS); the reductions could be obtained more cheaply with an integrated coal gasification combined cycle (IGCC) plant with CCS.

    1998-04-01

    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

    A number of countries have unilaterally committed themselves to limit emissions of greenhouse gases. Other countries have resisted such commitments; they prefer to engage in further climate research to determine the extent of any emissions reduction that may be necessary before committing themselves to significant costs to implement controls. This paper examines the costs of alternative policies including immediate action to limit emissions and climate research followed by controls if necessary. (Author)

    The paper presents the problem of excessive air pollution in Poland caused mainly by low emission. The emission arises in result of heating flats by means of old and energetically inefficient heating installations. In Poland and Bulgaria the inhaled air is of the worst quality out of all EU countries. The paper presents economic and technical problems related to low emission occurring during the combustion of solid fuels in local boiler houses. Furthermore, the most significant economic issues, connected with the reduction of low emission are discussed, as well as technological possibilities of efficient reduction of the amount of pollution in the atmosphere. Conclusions are presented at the end of the article.

    Societal risks increase as Earth warms, and increase further for emissions trajectories accepting relatively high levels of near-term emissions while assuming future negative emissions will compensate, even if they lead to identical warming as trajectories with reduced near-term emissions1. Accelerating carbon dioxide (CO2) emissions reductions, including as a substitute for negative emissions, hence reduces long-term risks but requires dramatic near-term societal transformations2. A major barrier to emissions reductions is the difficulty of reconciling immediate, localized costs with global, long-term benefits3,4. However, 2 °C trajectories not relying on negative emissions or 1.5 °C trajectories require elimination of most fossil-fuel-related emissions. This generally reduces co-emissions that cause ambient air pollution, resulting in near-term, localized health benefits. We therefore examine the human health benefits of increasing 21st-century CO2 reductions by 180 GtC, an amount that would shift a `standard' 2 °C scenario to 1.5 °C or could achieve 2 °C without negative emissions. The decreased air pollution leads to 153 ± 43 million fewer premature deaths worldwide, with 40% occurring during the next 40 years, and minimal climate disbenefits. More than a million premature deaths would be prevented in many metropolitan areas in Asia and Africa, and >200,000 in individual urban areas on every inhabited continent except Australia.

  15. Emissions trading in transition economies: the link between international and domestic policy

    International Nuclear Information System (INIS)

    Evans, M.

    2003-01-01

    International emissions trading has the potential to significantly lower carbon mitigation costs and to promote environmentally friendly investment in transition economies. The design of domestic systems to complement international emissions trading will likely play a major role in emissions trading's effectiveness. This paper examines the benefits and challenges of proposed domestic systems and the related flows of emissions trading revenue in seller nations. The overwhelming majority of emissions available for sale will come from transition economies, which is why this article considers these countries as a group. Governments in countries such as Russia and Poland are interested in the potentially significant revenue they would reap from emissions trading, and some in those governments feel the money would best be used as general revenue for the government. Others argue that emissions trading should involve the private sector and other emitters in order to provide maximum incentives to reduce emissions and generate additional emissions trading revenue (the rules for international emissions trading explicitly allow this). Still others feel that special carbon mitigation funds would allow the government to maintain control yet stimulate additional emission reductions. Each policy contains its own set of challenges: stimulating further emission reductions, credibly monitoring emissions and emission reductions, or applying adequate fiscal accounting to the money flows

  16. Differences in regional emissions in China's transport sector: Determinants and reduction strategies

    2016-01-01

    With recent surge in the number of vehicles, particularly private vehicles, the transport sector has significantly contributed to the increase in energy consumption and carbon dioxide emissions in China. Most of the existing researches utilized time series data to investigate the factors influencing transport sector's carbon dioxide emission at the national level while neglecting the level of regional differences. This paper adopts provincial panel data from 2000 to 2012 and panel data models to examine the key driving forces of carbon dioxide emissions in the transport sector at the regional level in China. The estimation results show that the impacts of urbanization on carbon dioxide emissions in the transport sector vary across regions and decline continuously from the western region to the eastern and central regions. Private vehicles are more important than cargo turnover in emission reduction because of its relatively inefficient and excessive growth. The role of energy efficiency improvement in mitigating carbon dioxide emissions in the three regions varies due to significant differences in research and development investment and management efficiency. Hence, in order to effectively achieve emission reduction, local governments should consider all these factors as well as regional heterogeneity in developing appropriate mitigation policies. - Highlights: • The factors of carbon dioxide emissions in China's transport sector were explored. • The impact of urbanization on carbon dioxide emissions varies across regions. • Private vehicles are more critical than cargo turnover in emission reduction. • The role of energy efficiency in the three regions is exactly the opposite.

    This study analyzes current energy and carbon dioxide (CO 2 ) emission trends in China's cement industry as the basis for modeling different levels of cement production and rates of efficiency improvement and carbon reduction in 2011–2030. Three cement output projections are developed based on analyses of historical production and physical and macroeconomic drivers. For each of these three production projections, energy savings and CO 2 emission reduction potentials are estimated in a best practice scenario and two continuous improvement scenarios relative to a frozen scenario. The results reveal the potential for cumulative final energy savings of 27.1 to 37.5 exajoules and energy-related direct emission reductions of 3.2 to 4.4 gigatonnes in 2011–2030 under the best practice scenarios. The continuous improvement scenarios produce cumulative final energy savings of 6.0 to 18.9 exajoules and reduce CO 2 emissions by 1.0 to 2.4 gigatonnes. This analysis highlights that increasing energy efficiency is the most important policy measure for reducing the cement industry's energy and emissions intensity, given the current state of the industry and the unlikelihood of significant carbon capture and storage before 2030. In addition, policies to reduce total cement production offer the most direct way of reducing total energy consumption and CO 2 emissions. - Highlights: ► This study models output and efficiency improvements in Chinese cement industry from 2011–2030. ► Energy savings and CO 2 emission reductions estimated for 3 scenarios relative to frozen scenario. ► Results reveal cumulative final energy savings potential of 27.1–37.5 EJ and 3.2–4.4 Gt CO 2 reductions. ► Increasing efficiency is the most important policy for reducing cement energy and emissions intensity.

  19. Greenhouse gas emissions trading and complementary policies. Developing a smart mix for ambitious climate policies

    Matthes, Felix C.

    2010-06-15

    A debate has - most notably as a result of the introduction of fixed caps within the framework of emissions trading - been raised about the need for using additional instruments of climate and energy policy. A common line of argument is that the targets set within the emissions trading scheme are going to be met with a high degree of certainty, and flexibility among the regulated stakeholders will lead to market-based discovery processes. Additional instruments would only generate additional costs and would therefore have to be rejected. However, closer analysis of these fundamental arguments shows that they are constructed on a very high level of abstraction and sometimes rely on strongly simplifying or idealising assumptions. Their theoretical assumptions are, at least in part, very questionable and do not correspond to conditions in the real world for climate and energy policy. At the same time the debate about policy instruments cannot be held autonomously of the specific context of the problem at hand. In this sense the very extensive (complete) and above all effective decarbonisation of the economies of industrialised countries in a comparatively short time frame is the key basic condition for the analysis, assessment and design of the climate policy mix. Essentially, the question is what the best instruments are for purging the whole economic system almost entirely of CO{sub 2} emissions within a period of only forty years. The introduction of emissions trading schemes for greenhouse gases in an increasing number of OECD countries undoubtedly constitutes an important landmark of climate policy. They: - provide a high degree of certainty in terms of meeting targets; - create, on the basis of a standardised price signal, a clearing mechanism for the broad spectrum of emission reduction options close to the market, at least in the short to medium term; and - represent, by means of linking, an interesting option in terms of the globalisation of climate policy

    Global concern with climate change has led to the development of a variety of solutions to monitor and reduce emissions on both local and global scales. Under the United Nations Framework Convention on Climate Change (UNFCCC), both developed and emerging countries have assumed responsibility for developing and updating national inventories of greenhouse gas emissions from anthropic sources. This creates opportunities and incentives for cities to carry out their own local inventories and, thereby, develop air quality management plans including both essential key players and stakeholders at the local level. The aim of this paper is to discuss the role of local inventories as an urban public policy instrument and how this type of local instrument may bring advantages countrywide in enhancing the global position of a country. Local inventories have been carried out in many cities of the world and the main advantage of this is that it allows an overview of emissions produced by different municipal activities, thereby, helps decision makers in the elaboration of efficient air quality management plans. In that way, measures aimed at the reduction of fossil fuel consumption to lower local atmospheric pollution levels can also, in some ways, reduce GHG emissions.

    This paper describes the energy-related components of the Clinton Administration's Climate Change Action Plan. The Action Plan was formulated to meet the Administration's commitment of returning US emissions of greenhouse gases to 1990 levels by the year 2000. The paper discusses what the energy industry and energy consumers will be requested to do in order to meet this commitment. Several themes addressed in this paper include: (1) the largely voluntary nature of the actions identified in the Action Plan; (2) consideration of diverse opportunities to reduce emissions; (3) the outlook for US greenhouse gas emissions after 2000; and (4) actions involved for speeding the utilization of new, energy efficient technologies both domestically and abroad. The value of employing a diverse set of activities and the important role of technology improvements will be explored further in section 10 of this volume: ''Greenhouse Gas Emission Mitigation Strategies.'' Papers presented there include the utilization of more efficient fossil energy technologies, energy conservation and demand-side management programs, renewable energy and reforestation, and carbon dioxide capture and disposal

    A second commitment period of the Kyoto Protocol has just started. International climate negotiations consistently keep new market based approaches on the agenda. Nationally Appropriate Mitigation Actions are rapidly rising as a new signature concept for a future climate treaty. In response to this momentum, many countries still find themselves in search of concrete emissions reduction options. UNEP Risoe, with the support of the UNFCCC Secretariat and the ACP-MEA Programme, has decided to assess the emissions reduction potential in 15 diverse countries. While most of these countries are not seen as obvious targets for emissions reduction activities, they are nevertheless likely to be involved in some form of future emissions reduction. Consequently, 15 country reports have been developed, from which this synthesis report gathers the main messages. The overall assessments of the potential emissions reduction in the 15 countries are presented. Sector details have been presented throughout the text, allowing an accumulation of overviews of the potentials in the 15 countries distributed across the 7 sectors of the economy around which the country reports have been structured. It is evident that the emissions reduction potential by far exceeds the current emissions reported by the UN, following calculations from the United States Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC). The reason for this is that these figures do not include the indirect emissions caused by current deforestation levels, as presented in the agro and forestry sections of the country reports. The intention behind including these figures is to illustrate that compared to these indirect emissions, almost any emissions reduction initiative, whether CDM or not - even those that may yield hundreds of thousands of tons of CO{sub 2} equivalents - are dwarfed by the main cause of emissions in these countries: deforestation. This source of emissions should be addressed with

    2016-01-01

    An emissions trajectory for the US consistent with 2 C warming would require marked societal changes, making it crucial to understand the associated benefits. Previous studies have examined technological potentials and implementation costs and public health benefits have been quantified for less-aggressive potential emissions-reduction policies, but researchers have not yet fully explored the multiple benefits of reductions consistent with 2 C. We examine the impacts of such highly ambitious scenarios for clean energy and vehicles. US transportation emissions reductions avoid approx.0.03 C global warming in 2030 (0.15 C in 2100), whereas energy emissions reductions avoid approx.0.05-0.07 C 2030 warming (approx.0.25 C in 2100). Nationally, however, clean energy policies produce climate disbenefits including warmer summers (although these would be eliminated by the remote effects of similar policies if they were undertaken elsewhere). The policies also greatly reduce damaging ambient particulate matter and ozone. By 2030, clean energy policies could prevent approx.175,000 premature deaths, with approx.22,000 (11,000-96,000; 95% confidence) fewer annually thereafter, whereas clean transportation could prevent approx.120,000 premature deaths and approx.14,000 (9,000-52,000) annually thereafter. Near-term national benefits are valued at approx.US$250 billion (140 billion to 1,050billion) per year, which is likely to exceed implementation costs. Including longer-term, worldwide climate impacts, benefits roughly quintuple, becoming approx.5-10 times larger than estimated implementation costs. Achieving the benefits, however, would require both larger and broader emissions reductions than those in current legislation or regulations.

    Industry and fossil fuel combustion are the main sources for urban carbon emissions. Most studies focus on energy consumption emission reduction and energy efficiency improvement. Material saving is also important for carbon emission reduction from a lifecycle perspective. IS (Industrial symbiosis) and U r S (urban symbiosis) have been effective since both of them encourage byproduct exchange. However, quantitative carbon emission reduction evaluation on applying them is still lacking. Consequently, the purpose of this paper is to fill such a gap through a case study in Kawasaki Eco-town, Japan. A hybrid LCA model was employed to evaluate to the lifecycle carbon footprint. The results show that lifecycle carbon footprints with and without IS and U r S were 26.66 Mt CO 2 e and 30.92 Mt CO 2 e, respectively. The carbon emission efficiency was improved by 13.77% with the implementation of IS and U r S. The carbon emission reduction was mainly from “iron and steel” industry, cement industry and “paper making” industry, with figures of 2.76 Mt CO 2 e, 1.16 Mt CO 2 e and 0.34 Mt CO 2 e, respectively. Reuse of scrape steel, blast furnace slag and waste paper are all effective measures for promoting carbon emission reductions.

Thus, we establish testable conditions as to whether a governmental emission-reduction commitment warrants the exploitation of gas, and whether such a strategy increases global emissions. We also characterize the extent to which this unilateral policy makes the rest...... of the world’s emission commitments more difficult to meet. Finally, we apply our results to the case of the US....

  10. California Air Resources board's mobil source emission reduction credit guidelines

    The California Air Resources Board has developed guidance for the generation and use of mobil source emission reduction credits. Mobil source credits can be used to improve air quality, or to mitigate increases in emissions associated with industrial and non-industrial sources. They are created by programs which reduce mobile source emission beyond the reductions required by federal, state, and local laws or air quality attainment plans. Significant amounts of credit can be generated by some types of programs which reduce mobile source emissions of oxides of nitrogen (NO x ) and reactive organic gases (ROG). Mobile source credit programs must be carefully structured to ensure that emission reductions are real, accurately quantified, enforceable, and have a defined life. Three potentially feasible programs for the creation of mobile source credits include accelerated retirement of older vehicles, purchase of low-emission buses, and purchase of zero-emission vehicles. These programs are evaluated for their ability to generate credit and to assess their cost effectiveness. Based on the examples presented, two methods of generating mobile source credits, the accelerated retirement of older vehicles and the purchase of low-emission buses, appear to be cost-effective when compared to other emission control measures

    Carbon emissions from drained peatlands converted to agriculture in Southeast Asia (i.e. Peninsular Malaysia, Sumatra and Borneo) are globally significant and increasing. Here, we map the growth of Southeast Asian peatland agriculture and estimate CO 2 emissions due to peat drainage in relation to official land-use plans with a focus on the Reducing Emissions from Deforestation and Degradation (REDD+) related Indonesian moratorium on granting new concession licenses for industrial agriculture and logging. We find that, prior to 2010, 35% of Southeast Asian peatlands had been converted to agriculture, principally by smallholder farmers (15% of original peat extent) and industrial oil palm plantations (14%). These conversions resulted in 1.46-6.43 GtCO 2 of emissions between 1990 and 2010. This legacy of historical clearances on deep peat areas will contribute 51% (4.43-11.45 GtCO 2 ) of projected peatland CO 2 emissions over the period 2010-2130. In Indonesia, which hosts most of the region's peatland and where concession maps are publicly available, 70% of peatland conversion to agriculture occurred outside of known concessions for industrial plantation development, with smallholders accounting for 60% and industrial oil palm accounting for 34%. Of the remaining Indonesian peatswamp forest (PSF), 45% is not protected, and its conversion would amount to CO 2 emissions equivalent to 0.7-2.3% (5.14-14.93 Gt) of global fossil fuel and cement emissions released between 1990-2010. Of the peatland extent included in the moratorium, 48% was no longer forested, and of the PSF included 40-48% is likely to be affected by drainage impacts from agricultural areas and will emit CO 2 over time. We suggest that recent legislation and policy in Indonesia could provide a means of meaningful emission reductions if focused on revised land-use planning, PSF conservation both inside and outside agricultural concessions, and the development of agricultural practices based on

    The two long-term scenarios carried out for Mexico attempt to paint a picture of carbon emissions and energy use in the year 2025. The scenarios reveal that Mexico's current energy path is not optimal; the energy-intensity indicators show an increasing reliance on petroleum products and electricity over the next 40 years. Thus, Mexico must embark on a program of energy conservation in the near future. Mexico recently has undertaken several energy conservation efforts. The Mexican government implemented a National Program for Energy Modernization. This program identifies the promotion of energy conservation in Mexico as one of its top priorities between 1990 and 1994. It incorporates a number of actions geared at improving energy conservation, including: establishing pricing policies which pay special attention to electricity tariffs; setting aside budget appropriations for energy-savings programs; carrying out an energy diagnosis in the transportation and industrial sectors; promoting cogeneration and new legislation in this field; setting efficiency standards for equipment; initiating a public education campaign to inform people about energy conservation; promoting the participation of research institutes and consulting firms in the research of the technological aspects of energy-saving measures; and creating agreement with industrial and commerce associations

    The authors report simulations of different environmental policy measures concerning transports and buildings in France. First, they review measures which may entail a reduction of greenhouse gas emissions, and comment their emission reduction potential and their implementation costs. These measures are then ranked, and only those presenting a significant potential and an economically and technologically feasibility are finally considered. Their impact is then simulated by using different models which are adapted to the both sectors and to time ranges. The obtained results are compared to those obtained with a calibrated trend scenario and with a 'factor 4' scenario

    In order to meet the 1997 Kyoto treaty targets, U.S. carbon emissions must be severely curtailed. While top-down economic models predict that cutting carbon emissions will produce high costs, higher efficiency technology, such as residential electric heat pump water heaters, can cause carbon reduction to become profitable. In a single-family residence, replacing an electric resistance water heater with a heat pump water heater can reduce carbon emissions by 0.6 tons per year and produce savings of $1200 over a twelve-year period., rather than costs. National implementation of this single technology would reduce electric power plant carbon emissions by 5 percent. (Author)

    The development of urbanization is accelerating in China, and there are great pressures and opportunities in cities to reduce carbon emissions. An emissions inventory is a basic requirement for analyzing emissions of greenhouse gases (GHGs), their potential reduction and to realize low-carbon development of cities. This study describes a method to establish a GHGs emissions inventory in Chinese cities for 6 emission sources including industrial energy consumption, transportation, household energy consumption, commercial energy consumption, industrial processes and waste. Nanjing city was selected as a representative case to analyze the characteristics of carbon emissions in Chinese cities. The results show that carbon emissions in Nanjing have increased nearly 50% during the last decade. The three largest GHGs contributors were industrial energy consumption, industrial processes and transportation, which contributed 37-44%, 35-40% and 6-10%, respectively, to the total GHGs emissions. Per GDP carbon emissions decreased by 55% from 2002 to 2009, and the per capita and per GDP carbon emissions were comparable or even lower than the world average levels. These results have important policy implications for Chinese cities to control their carbon emissions. - Highlights: → Carbon emissions inventory using bottom-up methodology was firstly reported for a Chinese city. → Emission characteristics of Nanjing city were compared with other international cities. → Low carbon policies for Chinese cities were recommended based on the results of this research.

    The implementation of policies promoting integrated urban energy solutions (ICES) could allow a reduction in Canada's urban greenhouse gas (GHG) emissions by 2050. The concept and its related policies impact all urban sectors of the economy, such as residential, commercial, urban and inter-city personal transportation, freight transportation, waste and water. ICES policies are considered feasible and necessary, and many cities around the world, like Stockholm and Utrecht, have implemented them successfully. Sustainable land use policies should be the first to be developed since all urban form, transportation, and energy use decisions are made within the framework they generate. In the long term, moderate to aggressive ICES policies generate reductions of GHG emission and energy use but also an increase of 0.3-0.9% of the GDP. Aggressive ICES policies also allow a reduction in the structural unemployment and an increase of the number of jobs. While the effects of the implementation of targeted abatement policies such as the carbon tax or technology regulations are observed within a few years, ICES produce effects on a longer term. In the short term, they allow the release of money that could be spent by households to reduce the economic burden generated by abatement policies. In the longer term, they allow reductions to take over the effects of the short term policies, taking into consideration the increasing size of the population and the economy. Therefore, ICES policies seem to be an important part of comprehensive policy efforts intending to satisfy Canada's energy use and GHG emissions objectives. 218 refs., 49 tabs., 41 figs.

    High-temperature, natural gas-fired furnaces, especially those fired with preheated air, produce large quantities of NO{sub x} per ton of material processed. Regulations on emissions from industrial furnaces are becoming increasingly more stringent. In addition, competition is forcing operators to make their furnaces more productive and/or efficient. Switching from preheated air to industrial oxygen can increase efficiency and reduce NO{sub x}, but oxygen is significantly more costly than air and may not be compatible with the material being heated. What was needed, and what was developed during this project, is a technology that reduces NO{sub x} emissions while increasing furnace efficiency for both air- and oxy-fired furnaces. Oscillating combustion is a retrofit technology that involves the forced oscillation of the fuel flow rate to a furnace. These oscillations create successive, fuel-rich and fuel-lean zones within the furnace. Heat transfer from the flame to the load increases due to the more luminous fuel-rich zones, a longer overall flame length, and the breakup of the thermal boundary layer. The increased heat transfer shortens heat up times, thereby increasing furnace productivity, and reduces the heat going up the stack, thereby increasing efficiency. The fuel-rich and fuel-lean zones also produce substantially less NO{sub x} than firing at a constant excess air level. The longer flames and higher heat transfer rate reduces overall peak flame temperature and thus reduces additional NO{sub x} formation from the eventual mixing of the zones and burnout of combustibles from the rich zones. This project involved the development of hardware to implement oscillating combustion on an industrial scale, the laboratory testing of oscillating combustion on various types of industrial burners, and the field testing of oscillating combustion on several types of industrial furnace. Before laboratory testing began, a market study was conducted, based on the

    A global chemistry-climate model has been used to study the impacts of pollutants released by agriculture on fine particulate matter (PM2.5), with a focus on Europe, North America, South and East Asia. Hypothetical reduction of agricultural emission of 50%, 66% and 100% have been simulated and compared with the reference simulation. The simulations results reveal that a relatively strong reduction in PM2.5 levels can be achieved by decreasing agricultural emissions, and this effect can almost be exclusively explain by the reduction of ammonia (NH3) emissions, released from fertilizer use and animal husbandry. The absolute impact on PM2.5 reduction is strongest in East Asia, even for small emission decreases, although the relative reduction is very low (below 13% for a full removal of agricultural emissions) . Conversely, over Europe and North America, aerosol formation is not directly limited by the availability of ammonia. Nevertheless, reduction of NH3 can also substantially decrease PM2.5concentrations over the latter regions, especially when emissions are abated systematically and an ammonia limited regions of aerosol growth is reached. Further, our results document how reduction of agricultural emissions decreases aerosol pH due to the depletion of aerosol ammonium, which affects particle liquid phase and heterogeneous chemistry. It is calculated that ammonia emission controls could reduce the particle pH up to 1.5 pH-units in East Asia during winter, and more than 1.7 pH-units in South Asia, theoretically assuming complete agricultural emission removal, which could have repercussions for the reactive uptake of gases from the gas phase and the outgassing of relative weak acids. It is finally shown that a 50% reduction of agricultural emissions could prevent the mortality attributable to air pollution by 250 thousands people per year worldwide, amounting to reductions of 30%, 19% , 8% and 3% over North America, Europe and South Asia and East Asia, respectively

    Full Text Available This study reviewed and analyzed the specific practices, implementation effects and applicable conditions of fertilizer reduction policies in the EU, US and Japan, explored the common laws and general conditions in the formulation of environmental orientation, and pro vided feasible policy recommendations for the formulation of fertilizer reduction policies in China. This study showed that fertilizer reduction policies in each country had their own advantages and disadvantages, and the applicable conditions were different. The EU's command and control policy was applicable to the situation of less farm households and the same agricultural planting type or farm type. The economic in centive policy in the US was applicable to the situation of more farm households, relatively perfect agricultural market system and sensitive price formation mechanism, while the public participation policy in Japan was applicable to regions with more relevant agricultural groups and strong economy. China should learn from each of these policies and make a comprehensive choice in the formulation of fertilizer reduc tion policies. Therefore, China should proceed from improving the agricultural price mechanism and the pollution-free agricultural products certification system as well as encouraging and supporting the development of large scale production units, and then promote the adoption of environmentally friendly technology through the guidance of market mechanism, ensure the effective implementation of environmental stan dards through farmers' integration and improve farmers' environmental awareness through propaganda guidance, so as to ensure the effective implementation of different types(command and control policy, economic incentive policy and public participation policyof fertilizer reduc tion policies.

    The contribution of aviation to global carbon dioxide (CO 2 ) emissions is projected to triple by 2050. As nations strive to meet CO 2 reduction targets, policy interventions to manage the growth of emissions arising from air travel are likely. Here, we investigate the potential influence of aviation emissions reduction policies on the business travel patterns of individual corporations. Using travel data from six UK-based companies, we find that increased ticket prices can deliver substantial emissions cuts, particularly on premium class flights, and may provide strong financial incentives to seek modal and/or technological alternatives to flying. We also find that corporations from different business sectors vary in their responsiveness to a range of policy options. Finally, we examine questionnaire data to determine whether companies more broadly are going beyond compliance to mitigate their environmental impact by managing travel-related emissions voluntarily. Although many corporations are measuring and reporting emissions, only a limited number are willing to implement in-house reduction policies prior to regulation. - Research highlights: →Ticket price rises can deliver substantial emissions cuts, particularly on premium class flights. → Corporations from different business sectors vary in their responsiveness to policy options. → Many companies measure emissions but few will apply in-house reduction policies before regulation.

    Global warming and environment problems caused by the excessive emission of greenhouse gases (GHGs), along with rapid economic development has attracted the attention of many countries and regions of the world. Reducing GHG emissions is essential to mitigate the threat of global warming. Household carbon (dioxide) emissions have been recognized as one of the most important contributors to climate change, with a significant impact on both the local and global environment, and various policy instruments have been implemented by governments to bring about the reduction. This paper reviews these carbon abatement policy measures from demand-side and supply-side perspectives based on 144 countries across the world. The advantages and disadvantages of the policies are analyzed and it is found that income level largely affects the choice of policy, with high-income countries being mostly associated with demand-side policy instruments. Low-income countries adopt less demand-side policy measures and mainly depend on supply-side polices such as targets and regulations. Geographic location is also an important factor influencing the choice of policy instruments due to the different climates between different regions, although targets, regulations and carbon taxes are dominant GHG reduction policy measures worldwide. In America, tendering and net metering are popular, while in Europe feed-in-tariff (FIT) policies are implemented for more than 70% of the time. In Asia, policy measures, whether supply-side or demand-side, are comparatively weakly implemented and influenced by location, urbanization and economic growth. This paper suggests that, although the economic level is different, low-income countries and particularly developing countries can promote carbon abatement as well as the financial market by gradually changing from supply-side policy instruments to demand-side policies. This critical review provides a systematic understanding of various carbon emission policies in

    Affordable energy supply and reductions in emissions of local air pollution and greenhouse gases are each important aspects of South Africa's goals. Many traditional solutions, however, work in contradiction to one another. This work investigates effects on estimated emissions and costs of mitigation strategies using the Greenhouse Gas and Air Pollution Interaction Synergies (GAINS) model to identify policies that satisfy multiple goals. Eight scenarios that describe air pollution control options and mixes of energy production technologies are implemented in GAINS, which quantifies country-wide air pollution and greenhouse emissions and costs of controls. Emissions and costs trajectories are compared to the business as usual case, which projects CO_2 emissions to increase by 60% by 2050 compared to 2015. Results show that replacing all coal generation with renewables reduces CO_2 emissions in 2050 by 8% compared to 2015, and that aggressive policy targeting the whole energy sector reduces CO_2 emissions in 2050 by 40%. GAINS is used to show co-benefits and tradeoffs of each scenario, such as reductions in emissions control costs that accompany a switch to renewables. The approach provides supporting evidence for policies that exploit co-benefits and avoid contradictions by assessing multiple aspects of the energy sector within the integrated framework provided by the GAINS modeling platform.

    The electricity sector is responsible for roughly 40% of U.S. carbon dioxide (CO 2 ) emissions, and a reduction in CO 2 emissions from electricity generation is an important component of the U.S. strategy to reduce greenhouse gas emissions. Toward that goal, several proposals for a clean energy standard (CES) have been put forth, including one espoused by the Obama administration that calls for 80% clean electricity by 2035 phased in from current levels of roughly 40%. This paper looks at the effects of such a policy on CO 2 emissions from the electricity sector, the mix of technologies used to supply electricity, electricity prices, and regional flows of clean energy credits. The CES leads to a 30% reduction in cumulative CO 2 emissions between 2013 and 2035 and results in dramatic reductions in generation from conventional coal. The policy also results in fairly modest increases on national electricity prices, but this masks a wide variety of effects across regions. - Highlights: ► We model a clean energy standard (CES) for electricity at 80% by 2035. ► We analyze effects on CO 2 emissions, investment, prices, and credit trading. ► 80% CES leads to 30% reduction in cumulative CO 2 emissions by 2035. ► Modest national average electricity price increase masks regional heterogeneity

    The study describes and discusses in detail how four CDM reform alternatives, namely discounting of emission reductions, ambitious baselines, purchase and cancellation of CERs and reinvestment of CER levies, could be integrated in a Post-2012 climate regime. The study assesses these alternatives, according to their impacts on GHG emission reductions, contribution to sustainable development, cost-efficiency, technical feasibility, incentives and distributional effects as well as negotiability. The study shows that the introduction of discounting and ambitious baselines is technically feasible but politically a massive challenge. With the help of an economic model the study shows that the introduction of reform alternatives increases the amount of emission reductions but in comparison to the current CDM the impact is rather limited. But a CDM reform can in any case increase the credibility and improve the environmental integrity of the mechanism. (orig.)

  9. Policy Considerations for Greenhouse Gas Emissions from Freshwater Reservoirs

    Directory of Open Access Journals (Sweden)

    Kirsi Mäkinen

    2010-06-01

    Full Text Available Emerging concern over greenhouse gas (GHG emissions from wetlands has prompted calls to address the climate impact of dams in climate policy frameworks. Existing studies indicate that reservoirs can be significant sources of emissions, particularly in tropical areas. However, knowledge on the role of dams in overall national emission levels and abatement targets is limited, which is often cited as a key reason for political inaction and delays in formulating appropriate policies. Against this backdrop, this paper discusses the current role of reservoir emissions in existing climate policy frameworks. The distance between a global impact on climate and a need for local mitigation measures creates a challenge for designing appropriate mechanisms to combat reservoir emissions. This paper presents a range of possible policy interventions at different scales that could help address the climate impact of reservoirs. Reservoir emissions need to be treated like other anthropogenic greenhouse gases. A rational treatment of the issue requires applying commonly accepted climate change policy principles as well as promoting participatory water management plans through integrated water resource management frameworks. An independent global body such as the UN system may be called upon to assess scientific information and develop GHG emissions policy at appropriate levels.

    Full Text Available As European Union (EU candidate country, Macedonia is in the process of adoption of the EU strategic energy policies, harmonization of the national legislation with the EU legislation and defining the respective national goals. In this regard, the government has recently adopted a National Strategy for Utilization of Renewable Energy Sources (RES, prepared by ICEIM-MANU. The main goal of this paper is to assess the potential for greenhouse gases (GHG emissions reduction by implementation of 21%-RES-scenarios from the Strategy. The corresponding emissions reduction is calculated against the baseline (reference scenario developed within the Second National Communication on Climate Change. Furthermore, all potential RES technologies are analyzed from economic aspect and combined in a form of emissions reduction cost curve, displaying the total marginal cost of the GHG emissions reduction by RES. Finally, on the bases of the environmental and economic effectiveness of the considered RES technologies, as well as taking into account the country specific barriers, the priority actions for GHG emissions reduction are identified.

    Reducing global carbon dioxide (CO_2) emissions is often thought to be at odds with economic growth and poverty reduction. Using an integrated assessment modeling approach, we find that China can cap CO_2 emissions at 2015 level while sustaining economic growth and reducing the urban-rural income gap by a third by 2030. As a result, the Chinese economy becomes less dependent on exports and investments, as household consumption emerges as a driver behind economic growth, in line with current policy priorities. The resulting accumulated greenhouse gas emissions reduction 2016–2030 is about 60 billion ton (60 Mg) CO_2e. A CO_2 tax combined with income re-distribution initially leads to a modest warming due to reduction in sulfur dioxide (SO_2) emissions. However, the net effect is eventually cooling when the effect of reduced CO_2 emissions dominates due to the long-lasting climate response of CO_2. The net reduction in global temperature for the remaining part of this century is about 0.03 ± 0.02 °C, corresponding in magnitude to the cooling from avoiding one year of global CO_2 emissions. - Highlights: • China can cap CO_2-emissions at 2015 level without harming economic growth. • Poverty reduction is compatible with policy to cap CO_2 emissions. • Rural poverty reduction financed by CO_2 tax revenue increases domestic consumption. • One year of the global emissions is avoided. • The global mean temperature is reduced by 0.03 (± 0.02) °C.

The resulting accumulated greenhouse gas emissions reduction 2016–2030 is about 60 billion ton (60 Mg) CO{sub 2}e. A CO{sub 2} tax combined with income re-distribution initially leads to a modest warming due to reduction in sulfur dioxide (SO{sub 2}) emissions. However, the net effect is eventually cooling when the effect of reduced CO{sub 2} emissions dominates due to the long-lasting climate response of CO{sub 2}. The net reduction in global temperature for the remaining part of this century is about 0.03 ± 0.02 °C, corresponding in magnitude to the cooling from avoiding one year of global CO{sub 2} emissions. - Highlights: • China can cap CO{sub 2}-emissions at 2015 level without harming economic growth. • Poverty reduction is compatible with policy to cap CO{sub 2} emissions. • Rural poverty reduction financed by CO{sub 2} tax revenue increases domestic consumption. • One year of the global emissions is avoided. • The global mean temperature is reduced by 0.03 (± 0.02) °C.

    In this paper, we evaluate the changes in carbon dioxide emissions from energy consumption in China's food industry from 1986 to 2010 based on the Logarithmic Mean Divisia Index (LMDI) method. The results show that energy intensity (EI) and industrial activity (IA) are the main determinants of the changes in carbon dioxide. Energy intensity (EI) contributes to decrease in emissions within 25 years while industrial activity (IA) acts in a positive way to increase the emissions level. Industry scale (IS) mostly contributes to increase in emissions except for the time interval 1996–2000. However, for both carbon intensity (CI) and energy structure (ES), they have a volatile but not significant influence on emissions in the different time intervals. To further understand the effects, we analyze the cumulative emission during the whole period 1986–2010. The results further testify that energy intensity and industrial activity are the most important factors affecting reduction and growth of carbon emissions. The results indicate that efforts to reduce emission in China's food industry should focus on the enhancement of energy efficiency, the optimization of industrial scale and the restructuring energy use. Finally, recommendations are provided for the reduction of carbon dioxide in China's food industry. - Highlights: • We analyze the energy consumption and CO 2 emissions in China's food industry. • LMDI decomposition analysis is conducted for finding out the driving forces. • Industrial activity is the main driving force of CO 2 emissions in this industry. • Energy intensity is the main factor mitigating carbon emissions in this industry. • Main advice: improving energy efficiency, optimizing industrial scale.

    The rules governing their implementation and operation for implementing the Kyoto Protocol including emissions permit trading, project-based credit trading and the Clean Development Mechanism are to be decided at future talks. How these policies are eventually designed will determine the effectiveness of the Protocol. However, it has been passive and insufficient to deal with the Kyoto Protocol since there is no obligation on reduction of greenhouse gas emissions. Therefore, the issues on emissions permit trading are analyzed and the strategies for utilizing the Kyoto mechanism effectively are presented through reviewing the existing negotiation strategies. Moreover, how to use emissions permit trading in the power industry, the largest greenhouse gas emissions industry, is examined by dividing into two sections, domestic and abroad.

    The Arizona inspection and maintenance (I/M) program provides one of the first opportunities to examine the costs and effectiveness of vehicle emission repair. This paper examines various aspects of emission reductions, fuel economy improvements, and repair costs, drawing data from over 80,000 vehicles that failed the I/M test in Arizona between 1995 and the first half of 1996. We summarize the wealth of data on repair from the Arizona program and highlight its limitations. Because missing or incomplete cost information has been a serious shortcoming for the evaluation of I/M programs, we develop a method for estimating repair costs when they are not reported. We find surprising evidence that almost one quarter of all vehicles that take the I/M test are never observed to pass the test. Using a statistical analysis, we provide some information about the differences between the vehicles that pass and those that do not. Older, more polluting vehicles are much more likely never to pass the I/M test, and their expected repair costs are much higher than those for newer cars. This paper summarizes the evidence on costs and emission reductions in the Arizona program, comparing costs and emissions reductions between cars and trucks. Finally, we examine the potential for more cost-effective repair, first through an analysis of tightening I/M cut points and then by calculating the cost savings of achieving different emission reduction goals when the most cost-effective repairs are made first.

    The EU has set its short-term goals in the Europe 2020 Strategy (20% of CO 2 emissions reduction, 20% increase in energy efficiency, 20% share of renewables in final energy). The analyses show that the EU Member States in general are on the right track of achieving these goals; they are even ahead (including Slovenia). But setting long-term goals by 2050 is a tougher challenge. Achieving CO 2 emissions reduction goes hand in hand with increasing the share of renewables and strategically planning the projects, which include exploiting the potential of renewable sources of energy (e.g. hydropower). In Slovenia, the expected share of hydropower in electricity production from large HPPs in the share of renewables by 2030 is 1/3. The paper includes a presentation of a hydro power plants project on the middle Sava river in Slovenia and its specifics (influenced by the expansion of the Natura 2000 protected sites and on the other hand by the changes in the Environment Protection Law, which implements the EU Industrial Emissions Directive and the ETS Directive). Studies show the importance of the HPPs in terms of CO 2 emissions reduction. The main conclusion of the paper shows the importance of energy infrastructure projects, which contribute to on the one hand the CO 2 emissions reduction and on the other the increase of renewables.(author)

    Corporate excessive energy consumption and emissions are negative externality problems, with the basic countermeasure of establishing a series of institutional programs to promote corporate energy conservation and emissions reduction. This paper analyzes the influence of institutional factors such as laws, tax policies, credit policies, government subsidies, media supervision and marketization degree on corporate energy conservation and emissions reduction from the institutional perspective. The data, from 84 listed Chinese chemical and steel companies from 2006 to 2010, was analyzed using both a fixed effect model and the generalized method of moments (GMM) model. The empirical results demonstrate that these institutional factors positively affect corporate energy conservation and emissions reduction. Specifically, four factors – tax policies, government subsidies, credit policies and media supervision – have a significant positive relationship with corporate energy conservation and emissions reduction; whereas laws and marketization degree exhibit no significant effects. The research findings are theoretically and practically significant to the Chinese government with regard to improving the institutional environment and promoting corporate energy conservation and emissions reduction. - Highlights: ► Theoretical analysis of the influence of institutional factors based on NIE. ► Empirical analysis of the influence of institutional factors on ECER by regression. ► Economic measures and public opinions have positive influence on ECER in China. ► Laws and the degree of marketization have weak influence on ECER in China

    The 1997 Kyoto Conference introduced emissions trading as a new policy instrument for climate protection. Bringing together scholars in the fields of economics, political science and law, this book provides a description, analysis and evaluation of different aspects of emissions trading as an instrument to control greenhouse gases. The authors analyse theoretical aspects of regulatory instruments for climate policy, provide an overview of US experience with market-based instruments, draw lessons from existing trading schemes for the control of greenhouse gases, and discuss options for emissions trading in climate policy. They also highlight the background of climate policy and instrument choice in the US and Europe and of the emerging new systems in Europe, particularly the new EU's directive for a CO{sub 2} emissions trading system. 8 figs., 15 tabs.

    2016-01-01

    Highlights: • We build a carbon emissions reduction index (CERI). • The aim is to quantify the pressure on policymakers to reduce emissions. • Scale-related effects and carbon emissions allocations are included in the CERI. • Different standards of carbon emissions allocations are also considered. • We decompose the Gini coefficient to evaluate the effects of three factors. - Abstract: Given the acceleration of global warming and rising greenhouse gas emissions, all countries are facing the harsh reality of the need to reduce carbon emissions. In this study, we propose an index to quantify the pressure faced by policymakers to reduce such emissions, termed the carbon emissions reduction index. This index allows us to observe the effect of carbon emissions volume on the pressure faced by policymakers and study the impact of optimizing interregional carbon emissions on reducing this pressure. In addition, we account for several carbon emissions standards in constructing the index. We conclude that the variation in the index is likely to be attributable to carbon emissions volume, regional ranking, and population (population can also be replaced by GDP, resource endowment, or other factors). In addition, based on empirical data on the world’s largest emitter of carbon dioxide (China), this study analyzes the evolution of pressure to reduce emissions on a country’s policymakers. The results show that the growing volume and unsuitable allocation of carbon emissions from 1997 to 2012 imposed increasing pressure on the Chinese government in this regard. In addition, reductions in carbon emissions volume and regional ranking are primary factors that impact pressure on policymakers.

    Biomass cogeneration is widely used for district heating applications in central and northern Europe. Biomass trigeneration on the other hand, constitutes an innovative renewable energy application. In this work, an approved United Nations Framework Convention on Climate Change baseline methodology has been extended to allow the examination of biomass trigeneration applications. The methodology is applied to a case study in Greece to investigate various environmental and financial aspects of this type of applications. The results suggest that trigeneration may lead to significant emissions reduction compared to using fossil fuels or even biomass cogeneration and electricity generation. The emissions reduction achieved may be materialized into a considerable revenue stream for the project, if traded through a trading mechanism such as the European Union Greenhouse Gas Emission Trading Scheme. A sensitivity analysis has been performed to compensate for the high volatility of the emission allowances' value and the immaturity of the EU Trading Scheme, which prevent a reliable estimation of the related revenue. The work concludes that emission allowances trading may develop into one of the major revenue streams of biomass trigeneration projects, significantly increasing their financial yield and attractiveness. The impact on the yield is significant even for low future values of emission allowances and could become the main income revenue source of such projects, if emission allowances increase their value substantially. The application of trigeneration for district energy proves to lead to increased environmental and financial benefits compared to the cogeneration or electricity generation cases

    Full Text Available The objective of this study is to seek better policy options for greenhouse gas (GHG emission reduction in Korea’s international aviation industry by analyzing economic efficiency and environmental effectiveness with a system dynamics (SD model. Accordingly, we measured airlines sales and CO2 emission reductions to evaluate economic efficiency and environmental effectiveness, respectively, for various policies. The results show that the average carbon emission reduction rates of four policies compared to the business-as-usual (BAU scenario between 2015 and 2030 are 4.00% (Voluntary Agreement, 7.25% (Emission Trading System or ETS-30,000, 8.33% (Carbon Tax or CT-37,500, and 8.48% (Emission Charge System or EC-30,000. The average rate of decrease in airline sales compared to BAU for the ETS policy is 0.1% at 2030. Our results show that the ETS approach is the most efficient of all the analyzed CO2 reduction policies in economic terms, while the EC approach is the best policy to reduce GHG emissions. This study provides a foundation for devising effective response measures pertaining to GHG reduction and supports decision making on carbon tax and carbon credit pricing.

    Impacts of emissions changes from four potential U.S. CO2 emission reduction policies on 2050 air quality are analyzed using the community multiscale air quality model (CMAQ). Future meteorology was downscaled from the Goddard Institute for Space Studies (GISS) ModelE General Circulation Model (GCM) to the regional scale using the Weather Research Forecasting (WRF) model. We use emissions growth factors from the EPAUS9r MARKAL model to project emissions inventories for two climate tax scenarios, a combined transportation and energy scenario, a biomass energy scenario and a reference case. Implementation of a relatively aggressive carbon tax leads to improved PM2.5 air quality compared to the reference case as incentives increase for facilities to install flue-gas desulfurization (FGD) and carbon capture and sequestration (CCS) technologies. However, less capital is available to install NOX reduction technologies, resulting in an O3 increase. A policy aimed at reducing CO2 from the transportation sector and electricity production sectors leads to reduced emissions of mobile source NOX, thus reducing O3. Over most of the U.S., this scenario leads to reduced PM2.5 concentrations. However, increased primary PM2.5 emissions associated with fuel switching in the residential and industrial sectors leads to increased organic matter (OM) and PM2.5 in some cities.

    To explore public awareness of carbon capture and storage (CCS), attitudes towards the use of CCS and the determinants of CCS acceptance in China, a study was conducted in July 2009 based on face-to-face interviews with participants across the country. The result showed that the awareness of CCS was low among the surveyed public in China, compared to other clean energy technologies. Respondents indicated a slightly supportive attitude towards the use of CCS as an alternative technology to CO 2 emission reductions. The regression model revealed that in addition to CCS knowledge, respondents' understanding of the characteristics of CCS, such as the maturity of the technology, risks, capability of CO2 emission reductions, and CCS policy were all significant factors in predicting the acceptance of CCS. The findings suggest that integrating public education and communication into CCS development policy would be an effective strategy to overcome the barrier of low public acceptance.

    A geographic explicit techno-economic model, BeWhere (www.iiasa.ac.at/bewhere), has been developed at the European scale (Europe 28, the Balkans countries, Turkey, Moldavia and Ukraine) at a 40km grid size, to assess the potential of bioenergy from non-food feedstock. Based on the minimization of the supply chain from feedstock collection to the final energy product distribution, the model identifies the optimal bioenergy production plants in terms of spatial location, technology and capacity. The feedstock of interests are woody biomass (divided into eight types from conifers and non-conifers) and five different crop residuals. For each type of feedstock, one or multiple technologies can be applied for either heat, electricity or biofuel production. The model is run for different policy tools such as carbon cost, biofuel support, or subsidies, and the optimal mix of technologies and biomass needed is optimized to reach a production cost competitive against the actual reference system which is fossil fuel based. From this approach, the optimal mix of policy tools that can be applied country wide in Europe will be identified. The preliminary results show that high carbon tax and biofuel support contribute to the development of large scale biofuel production based on woody biomass plants mainly located in the northern part of Europe. Finally the highest emission reduction is reached with low biofuel support and high carbon tax evenly distributed in Europe.

    This report proposes an assessment of greenhouse gas emissions related to consumption in the world. It examines which are currently the world emission flows which come with trade exchanges (intermediate and final goods) between countries. The first part tries to highlight hidden emissions present in our imports and exports. It presents the different methods of greenhouse gas accounting, discusses the emission flows at the planet level, and the challenge of the limitation of 'carbon leaks', and discusses what makes a country a net emission importer or exporter. The second part discusses how France can reduce its consumption-based emissions, how to reach a factor 4 of reduction on these emissions, how to act against leaks and inflows of emissions through measures at the world level (international agreement, reduction of emissions by sea and air transport, reduction of industry emissions) or at the national level (relocation of polluting industries in France or Europe, promotion of short circuits, eco-design, changes in consumption modes, measures on groups of products which import emissions)

    Climate policy raises a number of challenges for the energy sector, the most significant being the transition from a high to a low-CO2 energy path in a few decades. Emissions trading has become the instrument of choice to help manage the cost of this transition, whether used at international or at domestic level. Act Locally, Trade Globally, offers an overview of existing trading systems, their mechanisms, and looks into the future of the instrument for limiting greenhouse gas emissions. Are current markets likely to be as efficient as the theory predicts? What is, if any, the role of governments in these markets? Can domestic emissions trading systems be broadened to activities other than large stationary energy uses? Can international emissions trading accommodate potentially diverse types of emissions targets and widely different energy realities across countries? Are there hurdles to linking emissions trading systems based on various design features? Can emissions trading carry the entire burden of climate policy, or will other policy instruments remain necessary? In answering these questions, Act Locally, Trade Globally seeks to provide a complete picture of the future role of emissions trading in climate policy and the energy sector.

    2012-01-01

    Biochar, a pyrolysis product of organic residues, is an amendment for agricultural soils to improve soil fertility, sequester CO2 and reduce greenhouse gas (GHG) emissions. In highly weathered tropical soils laboratory incubations of soil-biochar mixtures revealed substantial reductions for nitrous oxide (N2O) and carbon dioxide (CO2). In contrast, evidence is scarce for temperate soils. In a three-factorial laboratory incubation experiment two different temperate agricultural soils were amended with green waste and coffee grounds biochar. N2O and CO2 emissions were measured at the beginning and end of a three month incubation. The experiments were conducted under three different conditions (no additional nutrients, glucose addition, and nitrate and glucose addition) representing different field conditions. We found mean N2O emission reductions of 60 % compared to soils without addition of biochar. The reduction depended on biochar type and soil type as well as on the age of the samples. CO2 emissions were slightly reduced, too. NO3- but not NH4+ concentrations were significantly reduced shortly after biochar incorporation. Despite the highly significant suppression of N2O emissions biochar effects should not be transferred one-to-one to field conditions but need to be tested accordingly.

    The German agricultural emission inventory is designed as an instrument of policy advice. The essential aim is to describe the emitting processes so that options for reducing emissions can be quantified. The German agricultural emission model GAS-EM uses in the field of NH 3 emissions from soils and plants in the EMEP / CORINAIR Guidebook (EMEP / CORINAIR, 2002) proposed methods. These differ in emission factors between several types of fertilizers and their application to acre or grassland in function of the average spring temperature. In the field of emissions from animal husbandry GAS-EM follows a material flow approach, where initially the energy and nutrient requirements for a given power (here are weight, weight gain, milk yield, number of piglets, etc. involved) the excretion of metabolizable carbon compounds and the N excretion can be calculated with feces and urine. Subsequently, for all animal species emissions of nitrogen species NH 3 , NO, N 2 O and N 2 from the grazing, indoor housing, storage and distribution of farm fertilizers calculated. [de

    Concern about global climate change is growing, and many projects and researchers are committed to reducing greenhouse gases from all possible sources. International Maritime (IMO) has set a target of 20% CO2 reduction from shipping by 2020 and also presented a series of carbon emission reduction methods, which are known as Energy Efficiency Design Index (EEDI) and Energy Efficiency Operation Indicator (EEOI). Reviews on carbon emission reduction from all industries indicate that, Carbon Capture and Storage (CCS) is an excellent solution to global warming. In this paper, a comprehensive literature review of EEDI and EEOI and CCS is conducted and involves reviewing current policies, introducing common technologies, and considering their feasibilities for marine activities, mainly shipping. Current projects are also presented in this paper, thereby illustrating that carbon emission reduction has been the subject of attention from all over the world. Two case ship studies indicate the economic feasibility of carbon emission reduction and provide a guide for CCS system application and practical installation on ships.

    As an alternative transportation fuel to petrodiesel, biodiesel has been promoted within national energy portfolio targets across the world. Early estimations of low lifecycle greenhouse gas (GHG) emissions of biodiesel were a driver behind extensive government support in the form of financial incentives for the industry. However, studies consistently report a high degree of uncertainty in these emissions estimates, raising questions concerning the carbon benefits of biodiesel. Furthermore, the implications of feedstock blending on GHG emissions uncertainty have not been explicitly addressed despite broad practice by the industry to meet fuel quality standards and to control costs. This work investigated the impact of feedstock blending on the characteristics of biodiesel by using a chance-constrained (CC) blend optimization method. The objective of the optimization is minimization of feedstock costs subject to fuel standards and emissions constraints. Results indicate that blending can be used to manage GHG emissions uncertainty characteristics of biodiesel, and to achieve cost reductions through feedstock diversification. Simulations suggest that emissions control policies that restrict the use of certain feedstocks based on their GHG estimates overlook blending practices and benefits, increasing the cost of biodiesel. In contrast, emissions control policies which recognize the multifeedstock nature of biodiesel provide producers with feedstock selection flexibility, enabling them to manage their blend portfolios cost effectively, potentially without compromising fuel quality or emissions reductions.

    There is deficiency in the determination of emission reduction potential in the future, especially with consideration of uncertainty. Mitigation measures for some economic sectors have been proposed, but few studies provide an evaluation of the amount of PM emission reduction that can be obtained in future years by different emission reduction strategies. We attribute the absence of helpful mitigation strategy analysis to limitations in the technical detail of future emission scenarios, which result in the inability to relate technological or regulatory intervention to emission changes. The purpose of this work is to provide a better understanding of the potential benefits of mitigation policies in addressing global and regional emissions. In this work, we introduce a probabilistic approach to explore the impacts of retrofit and scrappage on global PM emissions from on-road vehicles in the coming decades. This approach includes scenario analysis, sensitivity analysis and Monte Carlo simulations. A dynamic model of vehicle population linked to emission characteristics, SPEW-Trend, is used to estimate future emissions and make policy evaluations. Three basic questions will be answered in this work: (1) what contribution can these two programs make to improve global emissions in the future? (2) in which regions are such programs most and least effective in reducing emissions and what features of the vehicle fleet cause these results? (3) what is the level of confidence in the projected emission reductions, given uncertain parameters in describing the dynamic vehicle fleet?

    This conference was held July 28--31, 1997 in La Jolla, California. The purpose of this conference was to provide a multidisciplinary forum for exchange of state-of-the-art information on diesel engine emissions issues. Diesel engine manufacturers have significantly reduced emission of nitrogen oxides and particulates over the last 12 years. Currently there is concern about the 4% contribution of carbon dioxide from the combustion of fossil fuels to the atmosphere and its role in the greenhouse effect. The 56 papers in this report are arranged under the following topical headings: Agency diesel engine emissions and concerns; Human health effects -- Diesel exhaust; Aftertreatment -- Non-thermal plasma; Aftertreatment and in-cylinder emissions reduction; Combustion, fuel, and air management; Fuels and associated technology; and Advanced technology. Selected papers have been indexed separately for inclusion in the Energy Science and Technology Database.

  2. Wellbeing Impacts of City Policies for Reducing Greenhouse Gas Emissions

    Full Text Available To mitigate climate change, city authorities are developing policies in areas such as transportation, housing and energy use, to reduce greenhouse gas emissions. In addition to their effects on greenhouse gas emissions, these policies are likely to have consequences for the wellbeing of their populations for example through changes in opportunities to take physical exercise. In order to explore the potential consequences for wellbeing, we first explore what ‘wellbeing’ is and how it can be operationalised for urban planners. In this paper, we illustrate how wellbeing can be divided into objective and subjective aspects which can be measured quantitatively; our review of measures informs the development of a theoretical model linking wellbeing to policies which cities use to reduce greenhouse gas emissions. Finally, we discuss the extent to which the links proposed in the conceptual model are supported by the literature and how cities can assess wellbeing implications of policies.

    The emission of greenhouse gases (GHG) generated by human activity is a major cause of global warming and climate change. There is considerable debate about the choice of the best mechanism to reduce emissions under a climate policy. The aim of this paper is to measure the impact of a policy of taxing GHG emissions on the Brazilian economy as a whole and on different household groups based on income levels in 2009. The following databases were used: Supply and Use Tables, Household Budget Survey, National Household Sample Survey and emissions data from the Brazilian Ministry of Science and Technology and Innovation. A price system from a national input–output model that incorporates the intensity of GHG emissions is used, as well as a consumption vector broken down into ten representative households with different income levels. The main results indicate that this taxation system was slightly regressive and had a small negative impact on output. There were, however, significant emissions reductions. - Highlights: • We measure the distributive impact of a taxation policy of GHG emissions in Brazil. • Poorest households have the highest expenditure emissions coefficient. • The poorest households are most affected by both reducing consumption and labor income. • Overall, the taxation was slightly regressive and had a small negative impact on output.

    Policies to reduce adverse health impacts of fine particulate matter (PM 2.5 ) require information on costs of abatement and associated costs. This paper explores the potential for cost-efficient control of anthropogenic primary PM 2.5 emissions in Finland. Based on a Kyoto-compliant energy projection, two emission control scenarios for 2020 were developed. 'Baseline' assumes implementation of PM controls in compliance with existing legislation. 'Reduction' assumes ambitious further reductions. Emissions for 2020 were estimated at 26 and 18.6 Gg a -1 for 'Baseline' and 'Reduction', respectively. The largest abatement potential, 3.0 Gg a -1 , was calculated for power plants and industrial combustion. The largest potential with marginal costs below 5000 Euro MG(PM 2.5 ) -1 was for domestic wood combustion, 1.7 Gg a -1 . For traffic the potential was estimated at 1.0 Gg a -1 , but was associated with high costs. The results from this paper are used in the policy-driven national integrated assessment modeling that explores cost-efficient reductions of the health impacts of PM

  6. Working Toward Policy-Relevant Air Quality Emissions Scenarios

    Though much work has been done to develop accurate chemical emission inventories, few publicly available inventories are appropriate for realistic policy analysis. Emissions from the electricity and transportation sectors, in particular, respond in complex ways to policy, technology, and energy use change. Many widely used inventories, such as the EPA National Emissions Inventory, are well-suited for modeling current air quality, but do not have the specificity needed to address "what if?" questions. Changes in electricity demand, fuel prices, new power sources, and emission controls all influence the emissions from regional power production, requiring a plant-by-plant assessment to capture the spatially explicit impacts. Similarly, land use, freight distribution, or driving behavior will yield differentiated transportation emissions for urban areas, suburbs, and rural highways. We here present results from three recent research projects at the University of Wisconsin—Madison, where bottom-up emission inventories for electricity, freight transport, and urban vehicle use were constructed to support policy-relevant air quality research. These three studies include: 1) Using the MyPower electricity dispatch model to calculate emissions and air quality impacts of Renewable Portfolio Standards and other carbon-management strategies; 2) Using advanced vehicle and commodity flow data from the Federal Highway Administration to evaluate the potential to shift commodities from truck to rail (assuming expanded infrastructure), and assess a range of alternative fuel suggestions; and 3) Working with urban planners to connect urban density with vehicle use to evaluate the air quality impacts of smart-growth in major Midwest cities. Drawing on the results of these three studies, and on challenges overcome in their execution, we discuss the current state of policy-relevant emission dataset generation, as well as techniques and attributes that need to be further refined in order

    This paper presents the results from a dynamic computer model of U.S. ethylene production, designed to explore implications of alternative climate change policies for the industry's energy use and carbon emissions profiles. The model applies to the aggregate ethylene industry but distinguishes its main cracker types, fuels used as feedstocks and for process energy, as well as the industry's capital vintage structure and vintage-specific efficiencies. Results indicate that policies which increase the cost of carbon of process energy-such as carbon taxes or carbon permit systems-are relatively blunt instruments for cutting carbon emissions from ethylene production. In contrast, policies directly affecting the relative efficiencies of new to old capital-such as R&D stimuli or accelerated depreciation schedules-may be more effective in leveraging the industry's potential for carbon emissions reductions.

  8. A healthy reduction in oil consumption and carbon emissions

    Reliance on oil as an energy source for private transportation produces increasingly unfavorable social, political and environmental conditions including climate change, dependence on foreign oil, and the need for difficult choices between oil production and protection of biological systems. At the same time, the population is increasingly sedentary due largely to our reliance on the automobile for transportation. Adoption and maintenance of healthy weights and healthier lifestyles by substituting walking or biking for short trips currently taken by car could simultaneously improve health and reduce oil consumption and carbon dioxide emissions. We calculate the reduction in oil consumption and carbon dioxide emissions possible in the United States if (1) obese and overweight conditions were eliminated from the adult population through the use of walking or biking for transportation, and (2) individuals between the ages of 10 and 64 adopted previously recommended levels of daily exercise by walking or biking instead of driving. Substantial co-benefits accompany widespread adoption of physical activity. Assuming substitution of cycling for driving, the reduction in gasoline demand is equivalent to 34.9% of current domestic oil consumption. This constitutes considerably more oil than is recoverable from the Arctic National Wildlife Refuge. The concomitant reduction in US carbon dioxide emissions would constitute approximately 10.9% relative to 1990 net US emissions and would be a substantial step toward satisfying the Kyoto Protocol

  10. National emissions from tourism: An overlooked policy challenge?

    Gössling, Stefan

    2013-01-01

    Tourism has been recognized as a significant greenhouse gas (GHG) emissions sector on a global scale. Yet, only few studies assess tourism's share in national emissions. This paper compares and analyses existing inventories of national emissions from tourism. Studies are difficult to compare, because they use different system boundaries and allocation principles, omitting or including lifecycle emissions and GHG other than CO 2 . By outlining and analysing these differences, the paper estimates the contribution made by tourism to national emissions, and its greenhouse gas intensity in comparison to other economic sectors. Results indicate that while emissions from tourism are significant in all countries studied, they may, in some countries, exceed ‘official' emissions as calculated on the basis of guidelines for national emission inventories under the Kyoto Protocol. This is a result of the fact that bunker fuels are not considered in national GHG inventories, leading to underestimates of the energy- and GHG intensity of tourism economies. While further growth in tourism emissions can be expected in all countries studied, energy-related vulnerabilities are already considerable in many of these. Climate policy for tourism, on the other hand, is largely non-existent, calling for immediate action to consider this sector in national legislation. - Highlights: • Emissions from tourism are equivalent to 5–150% of ’official’ national emissions. • Inconsistent methods are used to calculate national tourism emissions. • Tourism is an energy-intense economic sector compared to other sectors. • Emissions from tourism are growing rapidly. • National policy is not concerned with tourism-related emissions

    Ozone (O3) formation in the southeastern US is studied in relation to nitrogen oxide (NOx) emissions using long-term (1990s-2015) surface measurements of the Southeastern Aerosol Research and Characterization (SEARCH) network, U.S. Environmental Protection Agency (EPA) O3 measurements, and EPA Clean Air Status and Trends Network (CASTNET) nitrate deposition data. Annual fourth-highest daily peak 8 h O3 mixing ratios at EPA monitoring sites in Georgia, Alabama, and Mississippi exhibit statistically significant (p total oxidized nitrogen (NOy) mixing ratios at SEARCH sites declined in proportion to NOx emission reductions. CASTNET data show declining wet and dry nitrate deposition since the late 1990s, with total (wet plus dry) nitrate deposition fluxes decreasing linearly in proportion to reductions of NOx emissions by ˜ 60 % in Alabama and Georgia. Annual nitrate deposition rates at Georgia and Alabama CASTNET sites correspond to 30 % of Georgia emission rates and 36 % of Alabama emission rates, respectively. The fraction of NOx emissions lost to deposition has not changed. SEARCH and CASTNET sites exhibit downward trends in mean annual nitric acid (HNO3) concentrations. Observed relationships of O3 to NOz (NOy-NOx) support past model predictions of increases in cycling of NO and increasing responsiveness of O3 to NOx. The study data provide a long-term record that can be used to examine the accuracy of process relationships embedded in modeling efforts. Quantifying observed O3 trends and relating them to reductions in ambient NOy species concentrations offers key insights into processes of general relevance to air quality management and provides important information supporting strategies for reducing O3 mixing ratios.

    The 15 countries that formed the European Union at the time of the Kyoto protocol implementation, compelled themselves to reduce by 8%, on average and per year for the 2008-2012 period and with reference to a standard year that was for most European countries 1990, their greenhouse gas emissions. The European Union has recently stated that the reduction will be better than expected and will reach 14.2% on average per year if the member states realize their projects concerning reforestation or the purchase of international carbon emission allowances.

  14. Estimated emission reductions from California's enhanced Smog Check program.

    The U.S. Environmental Protection Agency requires that states evaluate the effectiveness of their vehicle emissions inspection and maintenance (I/M) programs. This study demonstrates an evaluation approach that estimates mass emission reductions over time and includes the effect of I/M on vehicle deterioration. It includes a quantitative assessment of benefits from pre-inspection maintenance and repairs and accounts for the selection bias effect that occurs when intermittent high emitters are tested. We report estimates of one-cycle emission benefits of California's Enhanced Smog Check program, ca. 1999. Program benefits equivalent to metric tons per day of prevented emissions were calculated with a "bottom-up" approach that combined average per vehicle reductions in mass emission rates (g/gal) with average per vehicle activity, resolved by model year. Accelerated simulation mode test data from the statewide vehicle information database (VID) and from roadside Smog Check testing were used to determine 2-yr emission profiles of vehicles passing through Smog Check and infer emission profiles that would occur without Smog Check. The number of vehicles participating in Smog Check was also determined from the VID. We estimate that in 1999 Smog Check reduced tailpipe emissions of HC, CO, and NO(x) by 97, 1690, and 81 t/d, respectively. These correspond to 26, 34, and 14% of the HC, CO, and NO(x) that would have been emitted by vehicles in the absence of Smog Check. These estimates are highly sensitive to assumptions about vehicle deterioration in the absence of Smog Check. Considering the estimated uncertainty in these assumptions yields a range for calculated benefits: 46-128 t/d of HC, 860-2200 t/d of CO, and 60-91 t/d of NO(x). Repair of vehicles that failed an initial, official Smog Check appears to be the most important mechanism of emission reductions, but pre-inspection maintenance and repair also contributed substantially.

    Full Text Available The objective of this paper is to highlight the importance of entrepreneurship and public policy toward poverty reduction in Nigeria. Entrepreneurship has proven to be a mechanism for poverty reduction through creation of employment opportunities, income as well as wealth. In some occasion entrepreneurs exploit opportunities at the expense of the existing policy to engage in activities that are not economically and socially productive. They neither create wealth nor do they improve on the economic performance of a country. The author conducted survey and interview to solicit for data from small and micro enterprises across Kano state and also used secondary information in analysing the situation in the country. Infrastructural decay, lack of coherent policies and institutional framework were partly responsible for escalating poverty in the Nigeria. Therefore, it is recommended that the government while designing a policy toward entrepreneurship attempt should be made to identify and encourage high impact entrepreneurs that will genuinely contribute in creating real jobs and poverty reduction.

    A multi-region, multi-sector dynamic computable general equilibrium model is applied to explore the economic and welfare effects of the pledges submitted by developed countries (Annex I countries) and major developing (non-Annex I) countries for 2020 under the Copenhagen Accord. In addition to analyzing scenarios reflecting the upper and lower bounds of the Copenhagen Pledges, one additional policy scenario where Annex I countries as a group reduce CO 2 -emissions by 30% in 2020 compared to 1990 levels, and where major non-Annex I countries reduce CO 2 emissions 15% below baseline, is also analyzed. Economic effects are measured as changes in GDP compared to baseline and welfare effects are measured via the equivalent variation. Assuming that countries with emission targets may trade certificates, average reductions in GDP for countries with targets range between 0.1% and 0.7% in 2020 for the policy scenarios. While the GDP losses are larger for major non-Annex I countries with emission targets compared to Annex I countries, this is not the case for the changes in welfare. With the exception of Mexico, the welfare losses for the major non-Annex I regions, as a percentage of projected GDP in 2020, are lower than for the large Annex I countries. - Highlights: → Copenhagen pledges are not ambitious in terms of global CO 2 -emission reductions. → Copenhagen pledges are not costly in terms of global GDP or welfare losses. → Reductions in GDP and welfare in 2020 are not evenly distributed across regions.→ Major non-Annex I countries face relatively larger reductions in GDP compared with Annex I countries.→ Copenhagen pledges do not result in large amounts of carbon leakage.

    Energy saving and emission reduction policies affects the development of high power industry, thereby affecting electricity demand, so the study of the electricity industry boom helps to master the national economy. This paper analyses the influence of energy saving and emission reduction on power generation structure and pollutant emission in power industry. Through the construction of electricity market composite boom index to indicate electricity boom, using boom index to study volatility characteristics and trend of electricity market. Here we provide a method for the enterprise and the government, that it can infer the overall operation of the national economy situation from power data.

    During the fall, winter, and spring of 1991-1992, a measurement program was conducted in Denver, Colorado to quantify the technical and economic effectiveness of oxygenated gasoline in reducing automobile carbon monoxide (CO) emissions. Emissions from 80,000 vehicles under a variety of operating conditions were measured before, during, and after the seasonal introduction of oxygenated gasoline into the region. Gasoline samples were taken from several hundred vehicles to confirm the actual oxygen content of the fuel in use. Vehicle operating conditions, such as cold starts and warm operations, and ambient conditions were characterized. The variations in emissions attributable to fuel type and to operating conditions were then quantified. This paper describes the measurement program and its results. The 1991-1992 Colorado oxygenated gasoline program contributed to a reduction in carbon monoxide (CO) emissions from gasoline-powered vehicles. The measurement program demonstrated that most of the reduction is concentrated in a small percentage of the vehicles that use oxygenated gasoline. The remainder experience little or not reduction in emissions. The oxygenated gasoline program outlays are approximately $25 to $30 million per year in Colorado. These are directly measurable costs, incurred through increased government expenditures, higher costs to private industry, and losses in fuel economy. The measurement program determined the total costs of oxygenated gasoline as an air pollution control strategy for the region. Costs measured included government administration and enforcement, industry production and distribution, and consumer and other user costs. This paper describes the ability of the oxygenated gasoline program to reduce pollution; the overall cost of the program to government, industry, and consumers; and the effectiveness of the program in reducing pollution compared to its costs

    The European Council has recently claimed to consider ambitious emission reduction targets (15 to 30 percent by 2020 as compared to 1990 levels) to limit global climate change. In light of the coexistent EU priorities under the Lisbon process, the authors analyze alternative unilateral EU emission control policies against their effects on EU (sectoral and economy-wide) competitiveness using a multi-sector, multi-region computable general equilibrium (CGE) model framework. For a given emission reduction target, the simulations show that alternative implementation rules (uniform versus sectorally differentiated carbon taxes) induce ambiguous impacts on sectoral competitiveness: For a uniform tax, relatively carbon-intensive EU industries face competitiveness losses, while carbon-extensive sectors improve their ability to compete internationally. Losses and gains are reinforced by the stringency of unilateral emission reduction targets. Thus, the implementation of an (economically efficient) uniform carbon tax induces structural change which inevitably goes at the expense of carbon-intensive industries. Vice versa, the authors find that more pronounced tax differentiation in favor of carbon-intensive industries can largely neutralize the negative impacts of emission constraints on their competitiveness, but goes at the expense of overall efficiency. In this case, adjustment costs of emission abatement will to a large extent be born by energy-extensive sectors in terms of a deteriorated ability to compete. As a middle course, moderate tax differentiation allows to sectorally balance competitiveness effects of emission control policies and at the same time limit overall efficiency losses. The authors find also that the level of tax differentiation to balance sectoral competitiveness effects and to limit overall efficiency losses is independent of the emission reduction target. Furthermore, the results indicate that the magnitude of sectoral competitiveness effects is

    ENPEP was used to analyze the role of nuclear power in mitigating carbon emission in power generation sector. In this study, base scenario reflects business as usual case in Korea. Additional two scenarios were established. One stands for fuel switch scenario, where nuclear power plants scheduled to be introduced after 2008 were assumed to be replaced by Coal Power Plant, the other one is established to see the impact of carbon tax. In this scenario carbon tax(50$/ton-C0 2 ) is imposed on coal power plants from 2008. It is resulted that fuel switch from nuclear to coal in power generation sector has a great effect on CO 2 emission, while carbon tax imposition makes a slight contribution to the reduction of CO 2 emission. These findings mean that the role of nuclear power in Korea is important in view of the GHG mitigation

    Highlights: • A real option-based model for the valuation of CDM projects is proposed. • This study investigates the impact of energy policies on the value of CDM projects. • Level of target emission and its schedule should be carefully designed. • Government subsidy facilitates the implementation of CDM projects. • Period for free emission allowance prevents promoting CDM projects. - Abstract: Emission trading has been considered a primary policy tool for emission reduction. Governments establish national targets for emission reduction and assign emission reduction goals to private entities to accomplish the targets. To attain the goal, private entities should perform offset projects that can produce emission credits or buy emission credits from the market. However, it is not easy for private entities to decide to implement the projects because energy policies associated with emission trading keep changing; thus, the future benefits of the offset projects are quite uncertain. This study presents a real option-based model to investigate how uncertain energy policies affect the financial viability of an offset project. A case study showed that the establishment of a target emission was attractive to the government because it could make the CDM project financially viable with a small amount of government subsidy. In addition, the level of the government subsidy could determine the investment timing for the CDM project. In this context, governments should be cautious in designing energy policies, because even the same energy policies could have different impacts on private entities. Overall, this study is expected to assist private entities in establishing proper investment strategies for CDM projects under uncertain energy policies

    2013-01-01

    This study addresses the possible impacts of energy and climate policies, namely corporate average fleet efficiency (CAFE) standard, renewable fuel standard (RFS) and clean energy standard (CES), and an economy wide equivalent carbon tax on GHG emissions in the US to the year 2045. Bottom–up and top–down modeling approaches find widespread use in energy economic modeling and policy analysis, in which they differ mainly with respect to the emphasis placed on technology of the energy system and/or the comprehensiveness of endogenous market adjustments. For this study, we use a hybrid energy modeling approach, MARKAL–Macro, that combines the characteristics of two divergent approaches, in order to investigate and quantify the cost of climate policies for the US and an equivalent carbon tax. The approach incorporates Macro-economic feedbacks through a single sector neoclassical growth model while maintaining sectoral and technological detail of the bottom–up optimization framework with endogenous aggregated energy demand. Our analysis is done for two important objectives of the US energy policy: GHG reduction and increased energy security. Our results suggest that the emission tax achieves results quite similar to the CES policy but very different results in the transportation sector. The CAFE standard and RFS are more expensive than a carbon tax for emission reductions. However, the CAFE standard and RFS are much more efficient at achieving crude oil import reductions. The GDP losses are 2.0% and 1.2% relative to the base case for the policy case and carbon tax. That difference may be perceived as being small given the increased energy security gained from the CAFE and RFS policy measures and the uncertainty inherent in this type of analysis. - Highlights: • Evaluates US impacts of three energy/climate policies and a carbon tax (CT) • Analysis done with bottom–up MARKAL model coupled with a macro model • Electricity clean energy standard very close to

    In this paper we use a technological model of Ireland's future car stock to simulate the impact of a range of policy measures on the baseline trend in energy demand in the period to 2030. The policies and measures modelled comprise meeting deployment targets for electric vehicles and compressed natural gas vehicles, an EU regulation for the improvement of vehicle efficiency, implementation of a national biofuel obligation, as well as several behavioural measures (encouraging modal shifting and reduced travel demand). The impact of the different measures simulated is measured in terms of their contribution to meeting Ireland's ambitious targets for energy savings, for renewable energy penetration and for greenhouse gas (GHG) emissions reductions. The results point to a possible improvement of 32% in car stock efficiency, the achievement of 7.8% renewable energy share of road and rail transport and a 22% reduction in non-ETS private car CO 2 emissions relative to 2009 levels. A scenario analysis on meeting the EV penetration target shows a significant range of CO 2 emissions reductions depending on the cars (and mileage) displaced and on the electricity generation portfolio. - Highlights: ► Private car policy scenarios for Ireland modelled. ► Impact of vehicle efficiency, fuel switching and behavioural measures evaluated. ► Highlights distance to EU non-ETS emissions and renewable energy targets. ► Analysis of EV target shows that GHG mitigation potential is very sensitive.

    We assess recent Chinese climate policy proposals in a multi-region, multi-sector computable general equilibrium model with a Chinese carbon emissions trading scheme (ETS). When the emissions intensity per GDP in 2020 is required to be 45% lower than in 2005, the model simulations indicate that the climate policy-induced welfare loss in 2020, measured as the level of GDP and welfare in 2020 under climate policy relative to their level under business-as-usual (BAU) in the same year, is about 1%. The Chinese welfare loss in 2020 slightly increases in the Chinese rate of economic growth in 2020. When keeping the emissions target fixed at the 2020 level after 2020 in absolute terms, the welfare loss will reach about 2% in 2030. If China's annual economic growth rate is 0.5 percentage points higher (lower), the climate policy-induced welfare loss in 2030 will rise (decline) by about 0.5 percentage points. Full auctioning of carbon allowances results in very similar macroeconomic effects as free allocation, but full auctioning leads to higher reductions in output than free allocation for ETS sectors. Linking the Chinese to the European ETS and restricting the transfer volume to one third of the EU's reduction effort creates at best a small benefit for China, yet with smaller sectoral output reductions than auctioning. These results highlight the importance of designing the Chinese ETS wisely.

When the emissions intensity per GDP in 2020 is required to be 45% lower than in 2005, the model simulations indicate that the climate policy-induced welfare loss in 2020, measured as the level of GDP and welfare in 2020 under climate policy relative to their level under business-as-usual (BAU) in the same year, is about 1%. The Chinese welfare loss in 2020 slightly increases in the Chinese rate of economic growth in 2020. When keeping the emissions target fixed at the 2020 level after 2020 in absolute terms, the welfare loss will reach about 2% in 2030. If China's annual economic growth rate is 0.5 percentage points higher (lower), the climate policy-induced welfare loss in 2030 will rise (decline) by about 0.5 percentage points. Full auctioning of carbon allowances results in very similar macroeconomic effects as free allocation, but full auctioning leads to higher reductions in output than free allocation for ETS sectors. Linking the Chinese to the European ETS and restricting the transfer volume to one third of the EU's reduction effort creates at best a small benefit for China, yet with smaller sectoral output reductions than auctioning. These results highlight the importance of designing the Chinese ETS wisely.

    The current situation , and the short-term and long-term outlook in emission reduction trading are reviewed from the point of view of a power marketer. The author's view is that while the concept of emission reduction credit (ERC) is easy enough to understand, i.e. a series of measures to reduce carbon dioxide production and enhance carbon sequestration, there is no standard definition, although there are a number of models under consideration. What is being sought is clear ownership and title, a clear understanding of what qualifies as a credit, credit for early action, commodity specifications and the ability to hedge. The author predicts that in the short-tem, industry will experiment with different types of transactions to gain experience and seek partners who are willing to share risk and development cost. In the longer-term, emission reduction credits will be bought and sold as commodities and traded, swapped or exchanged as part of a portfolio in bilateral trade transactions, and used in hedging against future liabilities.

    Full Text Available Biogas represents a promising source for the production of clean energy. The objective of this paper was to quantify the potential for the reduction of emissions to the environment during the production of electricity from biogas in comparison with environmental effects of the production of the same amount of electricity from fossil resources (coal from Kolubara basin and natural gas. Basis for comparison of environmental impacts in this work was the annual production of electricity in biogas plants of the total capacity of 80 MW. This study has shown that the annual production of electricity from biogas power plants of 80 MW results in: substitution of up to 840 kt of coal from Kolubara basin and 123.2 million m3 of natural gas; reduction in emissions of greenhouse gases in the range of 491.16 kt - 604.97 kt CO2-eq, depending on the energy efficiency of the process of electricity production from biogas; reduction in emissions of greenhouse gases up to 92.37 kt CO2-eq compared to the use of natural gas for electricity generation.

    Since the 1992 Earth Summit in Rio de Janeiro, global anthropogenic CO 2 emissions grew by 52% which caused an increase in 10.8% in the CO 2 concentration in the atmosphere, and it tipped the 400 ppm mark in May 2013. The Fifth Assessment Report on climate impacts from the Intergovernmental Panel on Climate Change (IPCC) confirmed earlier warnings that climate change is already stressing human communities, agriculture, and natural ecosystems, and the effects are likely to increase in the future. While European Union has long been committed to lowering carbon emissions, this places additional pressure on current EU goals for energy sector that includes significant reduction of CO 2 emissions. Current EU commitment has been formalized in so-called '20-20-20' plan, reducing carbon emissions, increasing energy efficiency and increasing energy production from renewables by 20% by 2020. Some EU member states are even more ambitious, like United Kingdom, planning to reduce carbon emissions by 80% by 2050. Bulk of carbon reduction will have to be achived in energy sector. In the power industry, most popular solution is use of solar and wind power. Since their production varies significantly during the day, for the purpose of base-load production they can be paired with gas-fired power plant. Other possible CO 2 -free solution is nuclear power plant. In this invited lecture, predicted cost of energy production for newly bulit nuclear power plant and newly built combination of wind or solar and gas-fired power plant are compared. Comparison was done using Levelized Unit of Energy Cost (LUEC). Calculations were performed using the Monte Carlo method. For input parameters that have biggest uncertainty (gas cost, CO 2 emission fee) those uncertainties were addressed not only through probability distribution around predicted value, but also through different scenarious.

  10. Does climate policy lead to relocation with adverse effects for GHG emissions or not? A first assessment of the spillovers of climate policy for energy intensive industry

    Energy-intensive industries play a special role in climate policy. World-wide, industry is responsible for about 50% of greenhouse gas emissions. The emission intensity makes these industries an important target for climate policy. At the same time these industries are particularly vulnerable if climate policy would lead to higher energy costs, and if they would be unable to offset these increased costs. The side effects of climate policy on GHG emissions in foreign countries are typically referred to as 'spillovers'. Negative spillovers reduce the effectiveness of a climate policy, while positive spillovers increase its effectiveness. This paper provides a review of the literature on the spillover effects of climate policy for carbon intensive industries. Reviews of past trends in production location of energy-intensive industries show an increased share of non-Annex 1 countries. However, this trend is primarily driven by demand growth, and there is no empirical evidence for a role of environmental policy in these development patterns. In contrast, climate models do show a strong carbon leakage of emissions from these industries. Even though that climate policy may have a more profound impact than previous environmental policies, the results of the modelling are ambiguous. The energy and carbon intensity of energy-intensive industries is rapidly declining in most developing countries, and reducing the 'gap' between industrialized and developing countries. Still, considerable potential for emission reduction exists, both in developing and industrialized countries. Technology development is likely to deliver further reductions in energy use and CO2 emissions. Despite the potential for positive spillovers in the energy-intensive industries, none of the models used in the analysis of spillovers of climate policies has an endogenous representation of technological change for the energy-intensive industries. This underlines the need for a better understanding of

  11. Tradeable emission permits in Dutch environmental policy. A utopia?

    1997-01-01

    Because of the lack of experience with permits in the Netherlands, and in view of the similarities between various other tradeable permit systems, the functioning of Dutch systems of tradeable fish, milk and manure quotas is discussed. Evaluation of these systems is based on criteria of effectiveness, target-group efficiency and government efficiency. These systems of tradeable permits appear to constitute a successful addition to the Dutch policy of direct regulation. Considering this, and the favorable American experience with the Emissions Trading Program, tradeable emission permits deserve a chance to be implemented in Dutch environmental policy. The question remains, however, whether the Dutch government is ready for such a step. 28 refs

    Full Text Available Ozone (O3 formation in the southeastern US is studied in relation to nitrogen oxide (NOx emissions using long-term (1990s–2015 surface measurements of the Southeastern Aerosol Research and Characterization (SEARCH network, U.S. Environmental Protection Agency (EPA O3 measurements, and EPA Clean Air Status and Trends Network (CASTNET nitrate deposition data. Annual fourth-highest daily peak 8 h O3 mixing ratios at EPA monitoring sites in Georgia, Alabama, and Mississippi exhibit statistically significant (p  <  0.0001 linear correlations with annual NOx emissions in those states between 1996 and 2015. The annual fourth-highest daily peak 8 h O3 mixing ratios declined toward values of ∼ 45–50 ppbv and monthly O3 maxima decreased at rates averaging ∼ 1–1.5 ppbv yr−1. Mean annual total oxidized nitrogen (NOy mixing ratios at SEARCH sites declined in proportion to NOx emission reductions. CASTNET data show declining wet and dry nitrate deposition since the late 1990s, with total (wet plus dry nitrate deposition fluxes decreasing linearly in proportion to reductions of NOx emissions by ∼ 60 % in Alabama and Georgia. Annual nitrate deposition rates at Georgia and Alabama CASTNET sites correspond to 30 % of Georgia emission rates and 36 % of Alabama emission rates, respectively. The fraction of NOx emissions lost to deposition has not changed. SEARCH and CASTNET sites exhibit downward trends in mean annual nitric acid (HNO3 concentrations. Observed relationships of O3 to NOz (NOy–NOx support past model predictions of increases in cycling of NO and increasing responsiveness of O3 to NOx. The study data provide a long-term record that can be used to examine the accuracy of process relationships embedded in modeling efforts. Quantifying observed O3 trends and relating them to reductions in ambient NOy species concentrations offers key insights into processes of general relevance to air quality management and

    The international climate community has begun to assess a range of possible options for strengthening the international climate change effort after 2012. Analysis of the potential for sector-based emissions reduction and relevant mitigation options will provide the necessary background information for the debate. In order to assess the CO 2 abatement potential of China's steel industry, a model was developed using LEAP software to generate 3 different CO 2 emission scenarios for the industry from 2000 to 2030. The abatement potentials of different scenarios were compared, and their respective feasibilities were assessed according to the cost information. High priority abatement measures were then identified. The results show that the average CO 2 abatement per year in the Recent Policy scenario and in the New Policy scenario, compared with the reference scenario, are 51 and 107 million tons, respectively. The corresponding total incremental costs are 9.34 and 80.95 billion dollars. It is concluded that there is great potential for CO 2 abatement in China's steel industry. Adjusting the structure of the industry and technological advancement will play an important role in emissions reduction. Successful implementation of current sustainable development policies and measures will result in CO 2 abatement at a low cost. However, to achieve higher levels of abatement, the cost will increase dramatically. In the near future, specific energy conservation technologies such as dry coke quenching, exhaust gas and heat recovery equipment will be of great significance. However, taking a long term perspective, emissions reduction will rely more on the adjustment of production processes and the application of more modern large scale plants. Advanced blast furnace technology will inevitably play an important role

    Full Text Available Tobacco consumption is a major causative agent for various deadly diseases such as coronary artery disease and cancer. It is the largest avoidable health risk in the world, causing more problems than alcohol, drug use, high blood pressure, excess body weight or high cholesterol. As countries like Indonesia prepare to develop national policy guidelines for tobacco harm reduction, the scientific community can help by providing continuous ideas and a forum for sharing and distributing information, drafting guidelines, reviewing best practices, raising funds, and establishing partnerships. We propose several strategies for reducing tobacco consumption, including advertisement interference, cigarette pricing policy, adolescent smoking prevention policy, support for smoking cessation therapy, special informed consent for smokers, smoking prohibition in public spaces, career incentives, economic incentives, and advertisement incentives. We hope that these strategies would assist people to avoid starting smoking or in smoking cessation.

  17. Examining the role of policy design and policy interaction in EU automotive emissions performance gaps

    2017-01-01

    In the wake of the 2015 ‘Dieselgate’ scandal, the US and European governments publicly confronted automakers about their behaviour, which raised concerns about the integrity of the current emissions legislation regimes. In this article, I argue that ‘flexibilities’ within the EU's emissions legislative framework afforded automakers the opportunity to legally sidestep strict performance standards laid out in the law and resulted in a significant performance gap in real world driving emissions. This article provides a timely examination of EU emission legislation policy design and policy interaction within the European Union with the aim of explaining why the EU policy framework failed to regulate the regional automotive industry. Current research is mostly concerned with the typology and effectiveness of individual environmental policy instruments, be it regulatory or economic incentives, that aim to influence industry behaviour. This article approaches the current EU policy regime in a more holistic manner and focuses on the exploitation of weaknesses in the regulatory framework by private firms, which has received little academic attention in the innovation and transition literature. A major contribution of this article therefore is a body of primary qualitative interview data from industry elites concerning relevant emissions policies. - Highlights: • Significant performance gaps exist between stated and real-world car emissions. • Real-world performance gaps exist due to exploitation of flawed EU policy design. • Diesels have the widest performance gaps and are most harmful to air quality. • Policy interaction compounds EU air quality problems and promotes path-dependency. • Closing performance gaps requires policy revisions and more enforcement autonomy.

  18. The economic impact of emission peaking control policies and China's sustainable development

    2014-12-01

    Full Text Available To achieve the goals of national sustainable development, the peaking control of CO2 emissions is pivotal, as well as other pollutants. In this paper, we build a Chinese inter-regional CGE model and simulate 13 policies and their combinations. By analyzing the energy consumptions, coal consumptions, relating emissions and their impacts on GDP, we found that with the structure adjustment policy, the proportion of coal in primary fossil fuels in 2030 will decrease from 53% to 48% and CO2 emissions will decrease by 11.3%–22.8% compared to the baseline scenario. With the energy intensity reduction policy, CO2 emissions will decrease by 33.3% in 2030 and 47.8% in 2050 than baseline scenario. Other pollutants will also be controlled as synergetic effects. In this study we also find that although the earlier the peaking time the better for emission amounts control, the economic costs can not be ignored. The GDP will decrease by 2.96%–8.23% under different scenarios. Therefore, integrated policy solutions are needed for realizing the peaks package and more targeted measures are required to achieve the peaks of other pollutants earlier.

  19. The relative magnitude of the impacts and effects of GHG-related emission reductions

    2000-01-01

    A preliminary assessment of the current knowledge related to the co-benefits associated with climate change mitigation was provided in this document. One of the benefits of the reduction of greenhouse gas emissions is the reduction of other pollutants like sulphur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, particulate matter, ground-level ozone, heavy metals and other toxic pollutants. Since these pollutants have an effect on acid deposition, ozone depletion and air quality, the environment, social welfare and human health, this paper provided an initial outline of the complex processes, interactions and uncertainties associated with this issue. Fossil fuels represent the major source of greenhouse gas (GHG) emissions in Canada. The reduction of emissions of GHG could have an impact on the Long Range Transport of air toxic substances, would help increase oxygen concentrations in the Northern Hemisphere, and lead to less carbon monoxide being released in the atmosphere, among others effects. Reductions of GHG emissions would also have an impact on ecosystems by reducing ground-level ozone concentrations. There would be less acid deposition and more dissolved organic carbon, allowing less ultraviolet-B penetration in aquatic ecosystems. In the case of human health, improved air quality impacts on the avoidance of premature mortality and reduced morbidity. Numerous other co-benefits were listed and discussed in this document. The first section stated the purpose and objectives. In section 2, that authors described the science and policy context and discussed building an analytical framework in section 3. The impact of GHG emission reductions on atmospheric pollution and ecosystems was dealt with in section 4 and section 5 was devoted to providing an assessment of the relative magnitude of effects. In section 6, the significance of scope was reviewed, and the authors concluded with section 7 in which they discussed the next steps: phase II

  20. The Importance of Policy Neutrality for Lowering Greenhouse Gas Emissions

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available The drive by Canadian governments, at the provincial and federal level, to lower greenhouse gas emissions has resulted in a hodgepodge of different policy approaches. Some governments have opted for energy taxes, others for regulated limits on total emissions or emission intensity. Unfortunately, not all policy solutions are created equal; some are more effective than others in lowering total emissions and, worse still, may exact a heavy price on the economy. Policy-makers require a better understanding of how various policies affect the health of an economy and of how to mitigate the most pernicious costs. Key to gaining this improved understanding is to recognize one simple fact: some firms are more productive than others. As a consequence, it matters how workers, machines, energy, and other inputs are distributed between these firms. More productive firms should be larger — it is that simple. Some policies, however, increase input costs differently across firms and create costly distortions. Energy intensity targets are a clear example of a policy that disproportionately burdens lower productivity firms, changing firm sizes for the worse and even leading some to shut down altogether. Using a detailed model of production and energy use that matches the Canadian economy, we explore the consequences of the several forms that energy intensity regulations can take. We find the best approach to lowering greenhouse gas emissions is one that is neutral across firms — one that affects the cost of energy for smaller firms no more, or less, than larger ones. The only policy that fulfils this criterion is a flat energy tax. However, a flat tax on energy could well be politically unsellable in Canada, leaving governments to resort to politically palatable but economically risky intensity targets instead. Recognizing this, we explore a number of ways to improve the performance of intensity targets. First, governments should allow firms the option to

    Understanding the energy consumption and emissions associated with health services is important for minimizing their environmental impact and guiding their adaptation to a low-carbon economy. In this post-hoc analysis, we characterize the energy burden of North American emergency medical services (EMS) agencies and estimate the potential marginal damage costs arising from their emissions as an example of how and why health services matter in environmental and energy policy, and how and why environmental and energy policy matter to health services. We demonstrate EMS systems are energy intensive, and that vehicle fuels represent 80% of their energy burden while electricity and natural gas represent 20%. We also demonstrate that emissions from EMS operations represent only a small fraction of estimated health sector emissions, but for EMS systems in the United States the associated marginal damage costs are likely between $2.7 million and $9.7 million annually. Significant changes in the supply or price of energy, including changes that arise from environmental and energy policy initiatives designed to constrain fossil fuel consumption, could potentially affect EMS agencies and other health services. We encourage cross disciplinary research to proactively facilitate the health system's adaptation to a low-carbon economy. - Highlights: ► Estimated EMS-related emissions less than 1% of health sector emissions. ► Damage costs of U.S. EMS-related emissions estimated at $2.7 to $9.7 million. ► EMS energy burden is approximately 442 MJ per ambulance response. ► Approximately 80% of EMS energy burden is vehicle fuels. ► Energy supply, price and policy could impact EMS (and other health) services. ► Research needed to facilitate health services’ adaptation to a low carbon economy.

    This paper presented an integrated assessment for the design of greenhouse gas (GHG) emission reduction policies in British Columbia (BC) with particular reference to the drivers of GHG emissions from the transportation sector. Transportation services are central to the movement of goods and people in modern economies and their provision involves tradeoffs between economic benefits, health effects, and social and environmental impacts. More than a dozen BC initiatives were reviewed, with a specific focus on freight movement. The paper emphasized that consequences of proposals such as low carbon fuel standards need to be carefully assessed, along with mandated vehicle technologies, congestion fees and investment in alternative transportation infrastructure. The Activity, Modal Share, Intensity and Fuel (ASIF) framework was shown to provide insight into drivers of GHG emissions and the potential impact of policy decisions. The framework refers to factors such as the amount of kilometres traveled, share of activity per mode of travel, energy intensity, and GHG emissions per unit of energy for fuel type used in the transportation mode. The relationship between factors indicates that GHG emissions increase as energy intensity increases and as the carbon intensity of fuel increases. The overall intensity of the fleet depends greatly on vehicle composition and the share of travel between different modes. refs., tabs., figs.

    In recent years, the energy crisis and greenhouse effect problem have caused wide public concern, if these issues cannot be resolved quickly, they will bring troubles to people’s lives.In response, many countries around the world have implemented policies to reduce energy consumption and greenhouse gas emissions. In our country, the electric power industry has made great contribution to the daily life of people and the development of industry, but it is also an industry of high consumption and high emission.In order to realize the sustainable development of society, it is necessary to make energy conservation and emission reduction in the power industry as an important part of the realization of this goal.In this context, power generation trade has become a hot topic in energy conservation and emission reduction.Through the electricity consumption of the units with different power efficiency and coal consumption rate,it can achieve the target of reducing coal consumption, reducing network loss, reducing greenhouse gas emission, and increasing social benefit,and so on. This article put forward a optimal energy model on the basis of guaranteeing safety and environmental protection.In this paper, they used the IEEE30, IEEE39, IEEE57 and IEEE118 node system as an example, and set up the control groups to prove the practicality of the presented model.The solving method of this model was interior-point method.

    Green electricity generation can provide an indirect route to cleaner air: by displacing generation from fossil fuels, green electricity can reduce emissions of CO 2 and conventional air pollutants. Several types of voluntary markets have emerged in the United States to take advantage of this relationship, including green electricity programs, carbon offsets, and renewable energy certificates. At the same time, regulators are favoring cap-and-trade mechanisms for regulating emissions. This paper describes the appropriate framing of environmental claims for green electricity products. We apply an accounting framework for evaluating claims made for capped pollutants, with entries for emissions, avoided emissions due to green electricity, and unused emission permits. This framework is applied in case studies of two major electric utilities that operate with green electricity programs and capped pollutants. The cases demonstrate that the relative magnitude of 'unused permits' and 'emissions avoided' is a key relationship for evaluating an emissions reduction claim. Lastly, we consider the evolution of the green electricity marketplace given the reliance on cap-and-trade. In this setting, pollution-emission products could be decoupled from one another and from the various green electricity products. Several positive consequences could transpire, including better transparency of products, lower certification costs, and more product choices.

    Global carbon dioxide emissions need to be reduced by at least 50 to 85 % in 2050 compared to 2000 levels to limit global surface temperature increase to 2 C compared to preindustrial levels (IPCC 2007). As an intermediate greenhouse gas emission reduction target for industrialized countries in 2020 the IPCC (2007) confirmed a range of 25 % to 40 % compared to 1990, together with a substantial deviation from baseline in some developing regions, which was quantified as reductions in the range of 15 % to 30 % below baseline (den Elzen and Hoehne 2008). This report explores the environmental and economic effects of the pledges submitted by industrialized and major developing countries for 2020 under the Copenhagen Accord as quantifiable emission reductions or as NAMAs. Two scenarios reflect the lower (''weak'') and upper (''ambitious'') bounds of the Copenhagen pledges leading to emission reductions of 17 % below 1990 levels for Annex I countries and 13 % below reference levels for Non-Annex I countries. Both scenarios do not reach the level of ambition indicated as necessary by science to keep temperature increase below 2 C. In addition, two scenarios in accordance with the IPCC range for reaching a 2 C target are analyzed with industrialized countries in aggregate reducing their CO{sub 2}-emissions by 30 % and by 40 % in 2020 compared to 1990 levels, respectively. For all four policy scenarios the effects of emission paths leading to a global reduction target of 50 % below 1990 levels in 2050 are also simulated for 2030. In the scenarios for 2030 all but the least developed countries are assumed to take on emission targets, but emission caps are considerably less stringent for developing countries than for developed countries. In addition, a separate scenario is carried out which estimates the costs of an unconditioned EU 30 % emission reduction target. The analyses are carried out with the dynamic Computable General

    Since the passage of the Clean Air Act Amendments in 1990, there has been increasing interest among regulators and business interests alike in innovative, market-based strategies to air quality control. In particular, larger metropolitan areas have begun to examine marketable emission reduction credit (ERC) programs. These programs limit the total allowable emissions in a non-attainment area, allocate these emission open-quotes creditsclose quotes among sources in the region, and allow the sources to redistribute their allowances through trading. This approach provides for the most cost-effective distribution of control burdens among affected sources, taking advantage of the differences in marginal control costs. Some control measures applied to mobile sources may be significantly less expensive than those applied to stationary sources, making mobile sources an excellent candidate for inclusion in an ERC program. However, there are several potential problems involving quantification, enforcement, and credit trading issues that hinder the development of mobile source ERC programs. This paper will evaluate those obstacles and discuss how they are being addressed in a Natural Gas Vehicle (NGV) program currently under development for the Houston ozone non-attainment area. Specifically, the study will outline the credit validation (i.e., quantification) procedure, including baseline emission determination and emission testing for each NGV in the program. In addition, the study will describe the vehicle/fuel consumption tracking system, and discuss issues related to credit trading with stationary sources. Finally, observations are made concerning the applicability of mobile ERC programs for other emission control measures such as old vehicle scrappage and vehicle Inspection and Maintenance programs

    Since 1999, the International Monetary Fund and World Bank have required low-income countries soliciting for debt relief and financial support to prepare a Poverty Reduction Strategy Paper (PRSP). The objective of this study is to arrive at a systematic assessment of the extent to which the first batch of interim PRSPs actually addresses the health of the poor and vulnerable. A literature study was used to design and test a semi-quantitative approach to assess the pro-poor focus of health policies in national documents. The approach was applied to the existing interim proposals for 23 Highly Indebted Poor Countries. Results show that a majority of proposals lack country-specific data on the distribution and composition of the burden of disease, a clear identification of health system constraints and an assessment of the impact of health services on the population. More importantly, they make little effort to analyze these issues in relation to the poor. Furthermore, only a small group explicitly includes the interests of the poor in health policy design. Attention to policies aiming at enhancing equity in public health spending is even more limited. Few papers that include expenditure proposals also show pro-poor focused health budgets. We conclude that our systematic assessment of a new international development policy instrument, PRSP, raises strong concerns about the attributed role of health in development and the limited emphasis on the poor, the supposed primary beneficiaries of this instrument. There is a need and an opportunity for the international development community to provide assistance and inputs as poor countries shift their policy thinking from an interim stage to fully developed national policies. This paper presents a menu of analytical and policy options that can be pursued.

  10. A policy instruments working paper on reducing CO2 emissions from the transportation sector in Ontario

    International Nuclear Information System (INIS)

    1995-11-01

    The cost effectiveness of policy instruments for reducing CO 2 emissions from transportation was studied. Cost effectiveness analyzed the impact of the policy instruments in reducing CO 2 emissions against the costs that were incurred while obtaining CO 2 reductions. The approach to defining sustainable transportation was identified which integrates three different visions of the transportation challenge: (1) changing urban form to reduce the need for transportation, (2) advancing technology to reduce the ecological impact of transportation, and (3) changing prices of transportation so that users pay for the full social and environmental costs of their decisions. The general consensus was that while fuel tax on gasoline for automobiles appeared to be the most cost effective option available, all revenue generating options, (e.g.,parking pricing, reference energy factor-related rebates, full cost road pricing and taxation) rated higher on the cost effectiveness indexes than any of the other policy instruments considered. refs., tabs., figs

    2009-07-01

    This paper provided a summary of key achievements of the Program of Energy Research and Development advanced fuels and technologies for emissions reduction (AFTER) program over the funding cycle from fiscal year 2005/2006 to 2008/2009. The purpose of the paper was to inform interested parties of recent advances in knowledge and in science and technology capacities in a concise manner. The paper discussed the high level research and development themes of the AFTER program through the following 4 overarching questions: how could advanced fuels and internal combustion engine designs influence emissions; how could emissions be reduced through the use of engine hardware including aftertreatment devices; how do real-world duty cycles and advanced technology vehicles operating on Canadian fuels compare with existing technologies, models and estimates; and what are the health risks associated with transportation-related emissions. It was concluded that the main issues regarding the use of biodiesel blends in current technology diesel engines are the lack of consistency in product quality; shorter shelf life of biodiesel due to poorer oxidative stability; and a need to develop characterization methods for the final oxygenated product because most standard methods are developed for hydrocarbons and are therefore inadequate. 2 tabs., 13 figs.

    In contrast to Europe and North America, air pollution in Asia is increasing rapidly, resulting in both local air quality problems and higher acidic depositions. In 1989, an east-west group of scientists initiated a multi-institutional research project on Acid Rain and Emissions Reduction in Asia, funded for the past two years by the World Bank and the Asian Development Bank. Phase I, covering 23 countries of Asia, focused on the development of PC-based software called the Regional Air Pollution Information and Simulation Model (RAINS-ASIA). A 94-region Regional Energy Scenario Generator was developed to create alternative energy/emission scenarios through the year 2020. A long-range atmospheric transport model was developed to calculate dispersion and deposition of sulfur, based upon emissions from area and large point sources, on a one-degree grid of Asia. The resulting impacts of acidic deposition on a variety of vegetation types were analyzed using the critical loads approach to test different emissions management strategies, including both energy conservation measures and sulfur abatement technologies. 14 refs., 7 figs

    The CO 2 law stipulates quantitative targets for CO 2 emissions (reductions of 10% by 2010 compared with 1990, 15% for heating fuels, 8% for motor fuels). For motor fuels, it is currently estimated that the target will be missed by about 15%, or 2 to 2.5 million tonnes of CO 2 . In order to reach the targets, therefore, all measures that can be taken to reduce emissions are to be checked out and, where sensible and possible, implemented too. The subject of this study is the preferential treatment of diesel, natural gas, liquefied gas and bio-fuels as far as taxation is concerned, with compensation of tax losses on the petrol side. Also, the possibilities for promoting energy-efficient cars are looked at. The reduction of the price for diesel (at least 25 Swiss cents when compensated for via the petrol price) is considered to be unsuitable for reaching the targets because, in the final analysis, fuel sales - the determining factor for the CO 2 emissions that are charged to Switzerland - will increase instead of decreasing. Also, reservations are expressed from the environmental point of view (increased NO x emissions and, in particular, emissions of particulate matter). The modified measure proposed (fixed difference between the prices for petrol and diesel of 25 Swiss cents, for example) is looked at less critically, because it does actually lead to a reduction of CO 2 , even if only a modest one (approx. 10% of the gap to be bridged). On the environmental side, the same reservations apply. Bonus-malus systems, on the other hand, permit a selective choice of the objects of promotion (efficient and, possibly, low-emission vehicles), avoid the unjust preferential treatment of goods traffic and can be implemented without disturbing international price structures (fuel tourism). A bonus-malus system applied at purchase (e.g. different levels of car taxation) is considered to be more efficient than a differentiation in vehicle (road) tax. The promotion of gas is a

    The report reviews micro-economic reform in the energy market and measures the impact that energy market reform is expected to have on greenhouse gas outcomes. It indicates that reform in the electricity and gas industries is delivering what was promised, an efficient market with lower energy prices and, over the longer term, will deliver a gradually reducing rate of greenhouse gas emissions per unit of energy produced. It also recognises that energy market reform has removed some barriers to the entry of less greenhouse gas intense fuels. These trends will result in reduced greenhouse gas intensity in the supply of energy and significant reductions in the growth in greenhouse gas emissions compared to what may have been expected without the reforms

  15. Review of maritime transportation air emission pollution and policy analysis

    The study of air emission in maritime transportation is new, and the recognition of its importance has been rising in the recent decade. The emissions of CO2, SO2, NO2 and particulate matters from maritime transportation have contributed to climate change and environmental degradation. Scientifically, analysts still have controversies regarding how to calculate the emissions and how to choose the baseline and methodologies. Three methods are generally used, namely the ‘bottom up’ approach, the ‘top down’ approach and the STEEM, which produce very different results, leading to various papers with great uncertainties. This, in turn, results in great difficulties to policy makers who attempt to regulate the emissions. A recent technique, the STEEM, is intended to combine the former two methods to reduce their drawbacks. However, the regulations based on its results may increase the costs of shipping companies and cause the competitiveness of the port states and coastal states. Quite a few papers have focused on this area and provided another fresh perspective for the air emission to be incorporated in maritime transportation regulations; these facts deserve more attention. This paper is to review the literature on the debates over air emission calculation, with particular attention given to the STEEM and the refined estimation methods. It also reviews related literature on the economic analysis of maritime transportation emission regulations, and provides an insight into such analysis. At the end of this paper, based on a review and analysis of previous literature, we conclude with the policy indications in the future and work that should be done. As the related regulations in maritime transportation emissions are still at their beginning stage in China, this paper provides specific suggestions on how China should regulate emissions in the maritime transportation sector.

  16. Reduction of NOx emissions when burning low heating value gas

    Gustafsson, R.; Oskarsson, J.; Waldheim, L.

    1993-09-01

    On the gasification of nitrogen-rich fuel the nitrogen from the fuel goes into the gas phase in the form of ammonia and hydrogen cyanide and also nitrogen containing tars. When the gas is combusted the nitrogen compounds are oxidized to a great extent to NO x and, therefore, high NO x emissions can be found on the combustion of low heating value gas produced from energy forest wood chips as is also the case with direct combustion of nitrogen rich fuels. An experimental study has been carried out where the important parameters for designing a combustion chamber for low heating value gases have been studied in order to obtain maximum reduction of NO x emissions. The effect of tar cracking using dolomite on these emissions and the effect of parameters such as the addition of steam has also been tested. The tests were carried out with energy forest wood chips with 0.3% nitrogen. The gasification was carried out in a pyrolysis reactor, operated to yield a low heating value gas, and which was coupled to a simplified gas turbine combustion chamber at atmospheric pressure. The results show that the main part of the nitrogen in the fuel is found as ammonia in the low heating value gas. With this type of gasification the conversion of fuel nitrogen to ammonia in the gas is equivalent to 500-600 mg/MJ, calculated as NO 2 . Only very low amounts of hydrogen cyanide have been noted and no nitrogen containing tar components have been found. No apparent effect of steam additions has been noted. On the other hand the distribution of air in the combustion chamber and residence time during the under stoichiometric conditions are of great importance for the NO x reduction. Depending on the air distribution the emissions of NO 2 varied between 100 and 250 mg/MJ, calculated as NO 2 . 23 refs, 11 figs, 2 tabs

  17. The ranking of negative-cost emissions reduction measures

    2012-01-01

    A flaw has been identified in the calculation of the cost-effectiveness in marginal abatement cost curves (MACCs). The problem affects “negative-cost” emissions reduction measures—those that produce a return on investment. The resulting ranking sometimes favours measures that produce low emissions savings and is therefore unreliable. The issue is important because incorrect ranking means a potential failure to achieve the best-value outcome. A simple mathematical analysis shows that not only is the standard cost-effectiveness calculation inadequate for ranking negative-cost measures, but there is no possible replacement that satisfies reasonable requirements. Furthermore, the concept of negative cost-effectiveness is found to be unsound and its use should be avoided. Among other things, this means that MACCs are unsuitable for ranking negative-cost measures. As a result, MACCs produced by a range of organizations including UK government departments may need to be revised. An alternative partial ranking method has been devised by making use of Pareto optimization. The outcome can be presented as a stacked bar chart that indicates both the preferred ordering and the total emissions saving available for each measure without specifying a cost-effectiveness. - Highlights: ► Marginal abatement cost curves (MACCs) are used to rank emission reduction measures. ► There is a flaw in the standard ranking method for negative-cost measures. ► Negative values of cost-effectiveness (in £/tC or equivalent) are invalid. ► There may be errors in published MACCs. ► A method based on Pareto principles provides an alternative ranking method.

    Pollution emissions impose serious social negative externalities, especially in terms of public health. To reduce pollution emissions cost-effectively, the marginal abatement costs (MACs) of pollution emissions must be determined. Since the industrial sectors are the essential pillars of China's economic growth, as well as leading energy consumers and sulfur dioxide (SO₂) emitters, estimating MACs of SO₂ emissions at the industrial level can provide valuable information for all abatement efforts. This paper tries to address the critical and essential issue in pollution abatement: How do we determine the MACs of pollution emissions in China? This paper first quantifies the SO₂ emission contribution of different industrial sectors in the Chinese economy by an Input-Output method and then estimates MACs of SO₂ for industrial sectors at the national level, provincial level, and sectoral level by the shadow price theory. Our results show that six sectors (e.g., the Mining and Washing of Coal sector) should be covered in the Chinese pollution emission trading system. We have also found that the lowest SO₂ shadow price is 2000 Yuan/ton at the national level, and that shadow prices should be set differently at the provincial level. Our empirical study has several important policy implications, e.g., the estimated MACs may be used as a pricing benchmark through emission allowance allocation. In this paper, the MACs of industrial sectors are calculated from the national, provincial and sectoral levels; therefore, we provide an efficient framework to track the complex relationship between sectors and provinces.

  19. A rethink of how policy and social science approach changing individuals' actions on greenhouse gas emissions

    2012-01-01

    Social scientists from all areas are developing theories and testing practical approaches to change individuals' actions to lower greenhouse gas emissions. In the UK context, policy-makers, local authorities, companies and organisations are using these theories to invest resources to change individual's actions. The problem is that social scientists are delivering fragmented science based on narrow disciplinary views and those using this science are cherry picking whatever theory suits their agenda. We argue that with substantial GHG emission reduction targets to be achieved, a multidisciplinary application and view of social science are urgently needed.

    This study performed by the Energoproekt Company, Sofia (BG) is aimed at estimating the economic costs of CO 2 emissions reduction in the electricity supply system for the period 2000-2020. The specific capital investment and cost price of the following technical options have been compared: reduction of electricity and heat loss; gas and steam cycle power plants; micro hydro potential; renewable sources; extension of nuclear power installations; gas steam turbine equipment; combined cycle power plants. The evaluation is made according to requirements of a baseline scenario - to develop an import-independent energy supply policy and an economic growth without sharp structural changes. A 25-year-operation of a hypothetical energy supply system is modelled by the ENPEP code (ANL, US). The three least-cost options identified are: power loss reduction; gas and steam cycle PPs and hydroelectric objects. An optimal combination of measures, so called ' aggregated scenario' is proposed. It would allow for CO 2 reduction by 23,7 mill tons and prime cost reduction by $19,83 per ton reduced emissions. 3 refs., 2 tabs

  3. Cost-Sharing Contracts for Energy Saving and Emissions Reduction of a Supply Chain under the Conditions of Government Subsidies and a Carbon Tax

    Full Text Available To study the cooperation of upstream and downstream enterprises of a supply chain in energy saving and emissions reduction, we establish a Stackelberg game model. The retailer moves first to decide a cost-sharing contract, then the manufacturer determines the energy-saving level, carbon-emission level, and wholesale price successively. In the end, the retailer determines the retail price. As a regulation, the government provides subsidies for energy-saving products, while imposing a carbon tax on the carbon emitted. The results show that (1 both the energy-saving cost-sharing (ECS and the carbon emissions reduction cost-sharing (CCS contracts are not the dominant strategy of the two parties by which they can facilitate energy savings and emissions reductions; (2 compared with single cost-sharing contracts, the bivariate cost-sharing (BCS contract for energy saving and emissions reduction is superior, although it still cannot realise prefect coordination of the supply chain; (3 government subsidy and carbon tax policies can promote the cooperation of both the upstream and downstream enterprises of the supply chain—a subsidy policy can always drive energy saving and emissions reductions, while a carbon tax policy does not always exert positive effects, as it depends on the initial level of pollution and the level of carbon tax; and (4 the subsidy policy reduces the coordination efficiency of the supply chain, while the influences of carbon tax policy upon the coordination efficiency relies on the initial carbon-emission level.

    (1) We estimate CO 2 implicitly exported via commodities relative to a region's total emissions: We find −15% for the industrialized, 12% for the developing region, and 24% for China. (2) We analyze a Contraction and Convergence climate regime in a CGE model including international capital mobility and technology diffusion: When China does not participate in the regime and instead a carbon tariff is imposed on its exports, it will likely be worse off than when participating. This result does not hold for the developing region in general. Meanwhile, the effect on emissions appears small. - Highlights: ► Carbon intensities and contents of trade by commodity and region using GTAP 7. ► Net carbon exports: industrialized region −15%, developing region 12%, China 24%. ► CGE analysis of carbon tariffs based on our carbon intensities. ► The tariffs make China worse off than climate policy and are ambiguous for the developing region. ► They have a small impact on reducing global emissions.

    Objective: To understand the awareness of the health co-benefits of carbon emission reduction in urban residents in Beijing and the influencing factors, and provide information for policy decision on carbon emission reduction and health education campaigns. Methods: Four communities were selected randomly from Fangshan, Haidian, Huairou and Dongcheng districts of Beijing, respectively. The sample size was estimated by using Kish-Leslie formula for descriptive analysis. 90 participants were recruited from each community. χ (2) test was conducted to examine the associations between socio-demographic variables and individuals' awareness of the health co-benefits of carbon emission reduction. Ordinal logistic regression analysis was performed to investigate the factors influencing the awareness about the health co-benefits. Results: In 369 participants surveyed, 12.7 % reported they knew the health co-benefits of carbon emission reduction. The final logistic regression analysis revealed that age ( OR =0.98), attitude to climate warming ( OR =0.72) and air pollution ( OR =1.59), family monthly average income ( OR =1.27), and low carbon lifestyle ( OR =2.36) were important factors influencing their awareness of the health co-benefits of carbon emission reduction. Conclusion: The awareness of the health co-benefits of carbon emissions reduction were influenced by people' socio-demographic characteristics (age and family income), concerns about air pollution and climate warming, and low carbon lifestyle. It is necessary to take these factors into consideration in future development and implementation of carbon emission reduction policies and related health education campaigns.

  6. Policy options to reduce passenger car CO2 emissions after 2020

    The EU has set emission targets for new cars up to 2020 and is now preparing the post 2020 legislation. The present study aims to give insight in the design of policies to further reduce passenger car emissions after 2020. Internal combustion engine (ICE) vehicles are now expected to enable deeper and less costly CO2 emission reductions than envisioned until recently. However, even advanced ICE vehicles will not enable to meet the very stringent long term emission reduction targets for passenger cars. Therefore transport policies need not only to reduce emissions of ICE vehicles, but also ensure that electric and hydrogen vehicles are phased in timely, along with low-CO2 electricity and hydrogen. Current legislation to regulate tank-to-wheel vehicle emissions is based on CO2-limits, expressed in g CO2/km. On the short term it is important to maximize the efficiency of conventional vehicles. At the same time it is essential to foster the market introduction of electric and hydrogen vehicles, given their potential to reach eventually much deeper overall CO2-reductions. When the market share of electric and hydrogen vehicles grows it becomes increasingly important to maximize their efficiency and to minimize their upstream CO2 emissions. Maximizing both efficiency and overall CO2-performance of all vehicle types - ICE, electric, and hydrogen - will be complicated to achieve with a single CO2-based standard. At this point an efficiency-based standard is more effective, and may offer some additional benefits too. The current report provides basic directions of how such legislation could be shaped.

    2012-07-01

    Transport is the second biggest source of greenhouse gas (GHG) emissions in the EU, and contributes about one-quarter of the EU's total emissions of CO{sub 2}. Significant reductions in GHG emissions from transport are required if the EU is to achieve its long-term climate goals. This report examines the making and implementation of two of the regulations the EU has put in place to lower emissions from the transport sector: the EU's revised Fuel Quality Directive (Directive 2009/30/EC) and the cars/CO{sub 2} regulation (Regulation (EC) 443/2009). It was found that the relevance of various theories of policymaking in the EU varies with different policy phases. A policy-network understanding of EU policymaking is strengthened when assessing the policy-initiation phase. The Commission played a key role in this phase and drafted legislation in close collaboration with the car and oil refining industries. An intergovernmentalist understanding of EU policy-making is strengthened when assessing the decision-making phase. In this phase, member states defending the interests of their domestic industries had strong influence, but the European Parliament played an important role in this phase too, employing its power in the co-decision procedure. Finally, the implementation process is best understood as a multi-level governance process in which several actors and institutions - notably the Commission, member states, industries, and NGOs - influenced the process.

    2014-01-01

    The province of Alberta faces the challenge of balancing its commitment to reduce CO 2 emissions and the growth of its energy-intensive oil sands industry. Currently, these operations rely on the Alberta electricity system and on-site generation to satisfy their steam and electricity requirements. Most of the on-site generation units produce steam and electricity through the process of cogeneration. It is unclear to what extent new and existing operations will continue to develop cogeneration units or rely on electricity from the Alberta grid to meet their energy requirements in the near future. This study explores the potential for reductions in fuel usage and CO 2 emissions by increasing the penetration of oil sands cogeneration in the provincial generation mixture. EnergyPLAN is used to perform scenario analyses on Alberta’s electricity system in 2030 with a focus on transmission conditions to the oil sands region. The results show that up to 15–24% of CO 2 reductions prescribed by the 2008 Alberta Climate Strategy are possible. Furthermore, the policy implications of these scenarios within a deregulated market are discussed. - Highlights: • High levels of cogeneration in the oil sands significantly reduce the total fuel usage and CO 2 emissions for the province. • Beyond a certain threshold, the emissions reduction intensity per MW of cogeneration installed is reduced. • The cost difference between scenarios is not significant. • Policy which gives an advantage to a particular technology goes against the ideology of a deregulated market. • Alberta will need significant improvements to its transmission system in order for oil sands cogeneration to persist

    2012-01-01

    While support instruments have succeeded to largely deploy renewables during the 1996–2008 period, little attention has been paid to energy efficiency measures, resulting in a high energy intensity and large growth of energy demand. Energy-related CO 2 emissions have increased significantly. At the same time, important investments in combined cycle gas turbines have taken place. This paper analyses whether, from a cost minimization viewpoint, renewable support has been the best policy for reducing emissions, when compared to the promotion of energy efficiency in sectors such as transportation or buildings. We use a model of the Spanish energy sector to examine its evolution in the time period considered under different policies. It is a bottom-up, static, partial equilibrium, linear programming model of the complete Spanish energy system. We conclude that demand side management (DSM) clearly dominates renewable energy (RE) support if the reduction of emissions at minimum cost is the only concern. We also quantify the savings that could have been achieved: a total of €5 billion per year, mainly in RE subsidies and in smaller costs of meeting the reduced demand (net of DSM implementation cost). - Highlights: ► Energy efficiency is cheaper than renewables for reducing carbon emissions. ► Energy efficiency measures could have saved more than €5 billion per year in Spain. ► Savings could have been bigger without overcapacity in gas combined cycles.

    Full Text Available This study calculated the provincial carbon dioxide (CO2 emissions in China, analyzed the temporal and spatial variations in emissions, and determined the emission intensity from 2005 to 2015. The total emissions control was forecasted in 2015, and the reduction pressure of the 30 provinces in China was assessed based on historical emissions and the 12th five-year (2011–2015 reduction plan. Results indicate that CO2 emissions eventually increased and gradually decreased from east to west, whereas the emission intensity ultimately decreased and gradually increased from south to north. By the end of 2015, the total control of provincial emissions will increase significantly compared to the 2010 level, whereas the emission intensity will decrease. The provinces in the North, East, and South Coast regions will maintain the highest emission levels. The provinces in the Southwest and Northwest regions will experience a rapid growth rate of emissions. However, the national emission reduction target will nearly be achieved if all provinces can implement reduction targets as planned. Pressure indices show that the South Coast and Northwest regions are confronted with a greater reduction pressure of emission intensity.

    The Institute of Medicine recommends that public health agencies restrict the number and regulate the location of tobacco retailers as a means of reducing tobacco use. However, the best policy strategy for tobacco retailer reduction is unknown. The purpose of this study is to test the percent reduction in the number and density of tobacco retailers in North Carolina resulting from three policies: (1) prohibiting sales of tobacco products in pharmacies or stores with a pharmacy counter, (2) restricting sales of tobacco products within 1000 ft of schools, and (3) regulating to 500 ft the minimum allowable distance between tobacco outlets. This study uses data from two lists of tobacco retailers gathered in 2012, one at the statewide level, and another "gold standard" three-county list. Retailers near schools were identified using point and parcel boundaries in ArcMap. Python programming language generated a random lottery system to remove retailers within 500 ft of each other. Analyses were conducted in 2014. A minimum allowable distance policy had the single greatest impact and would reduce density by 22.1% at the state level, or 20.8% at the county level (range 16.6% to 27.9%). Both a pharmacy and near-schools ban together would reduce density by 29.3% at the state level, or 29.7% at the county level (range 26.3 to 35.6%). The implementation of policies restricting tobacco sales in pharmacies, near schools, and/or in close proximity to another tobacco retailer would substantially reduce the number and density of tobacco retail outlets.

    Accurate and verifiable emission reductions are a function of the degree of transparency and stringency of the protocols employed in documenting project- or program-associated emissions reductions. The purpose of this guide is to provide a background for law and policy makers, urban planners, and project developers working with the many Greenhouse Gas (GHG) emission reduction programs throughout the world to quantify and/or evaluate the GHG impacts of Natural Gas Vehicle (NGVs). In order to evaluate the GHG benefits and/or penalties of NGV projects, it is necessary to first gain a fundamental understanding of the technology employed and the operating characteristics of these vehicles, especially with regard to the manner in which they compare to similar conventional gasoline or diesel vehicles. Therefore, the first two sections of this paper explain the basic technology and functionality of NGVs, but focus on evaluating the models that are currently on the market with their similar conventional counterparts, including characteristics such as cost, performance, efficiency, environmental attributes, and range. Since the increased use of NGVs, along with Alternative Fuel Vehicle (AFVs) in general, represents a public good with many social benefits at the local, national, and global levels, NGVs often receive significant attention in the form of legislative and programmatic support. Some states mandate the use of NGVs, while others provide financial incentives to promote their procurement and use. Furthermore, Federal legislation in the form of tax incentives or procurement requirements can have a significant impact on the NGV market. In order to implement effective legislation or programs, it is vital to have an understanding of the different programs and activities that already exist so that a new project focusing on GHG emission reduction can successfully interact with and build on the experience and lessons learned of those that preceded it. Finally, most programs

    In this paper we address the current European Union's support policy for BEV (battery electric vehicles) manufacturing under the Super-credit modality, and its actual relationship with the reduction of carbon emissions derived from the use of battery electric vehicles (BEV). Particularly, we have estimated the BEV associated carbon emissions through the method provided by Intergovernmental Panel on Climate Change (IPCC). In this sense, we have employed a BEV model to investigate the BEV emissions by country in the EU according to the regional electricity mix. We additionally have accounted for the particularities of real-world driving, which further affects the results. We have employed a measure of driving aggressiveness by modifying the standard benchmarking driving cycle fostered by the European Union and of necessary application by vehicle manufacturers—the NEDC—to show that BEV emissions are not negligible when compared with internal combustion vehicles; mainly in urban environments. On the whole, in this paper we provide a revision framework of the Super Credits meant to support the increase of the BEV fleet in the European Union. In its current form, the Super-credits support policy is a constant ratio depending on the manufactured internal combustion vehicles. We claim, however, that they should depend on the BEV recipient country instead. By revising the European electricity mix, we demonstrate for instance that countries such as Poland, though indirectly, largely exceed the allowed limits of CO 2 emissions derived from the upstream generation of electricity required to load the BEV. - Highlights: • Super-credit support policy is aimed at promoting the manufacturing of BEV in the EU. • It does not account for upstream electricity generation in the BEV user country. • We analyze the generation emissions ensuing from the use of the BEV in EU countries. • We show that indirect carbon emissions in some countries exceed proposed targets.

  14. Impact Analysis of Air Pollutant Emission Policies on Thermal Coal Supply Chain Enterprises in China

    Full Text Available Spurred by the increasingly serious air pollution problem, the Chinese government has launched a series of policies to put forward specific measures of power structure adjustment and the control objectives of air pollution and coal consumption. Other policies pointed out that the coal resources regional blockades will be broken by improving transportation networks and constructing new logistics nodes. Thermal power takes the largest part of China’s total installed power generation capacity, so these policies will undoubtedly impact thermal coal supply chain member enterprises. Based on the actual situation in China, this paper figures out how the member enterprises adjust their business decisions to satisfy the requirements of air pollution prevention and control policies by establishing system dynamic models of policy impact transfer. These dynamic analyses can help coal enterprises and thermal power enterprises do strategic environmental assessments and find directions of sustainable development. Furthermore, the policy simulated results of this paper provide the Chinese government with suggestions for policy-making to make sure that the energy conservation and emission reduction policies and sustainable energy policies can work more efficiently.

    The present status of NO x emission from power stations and automobiles is first summarized, and the controlling regulations in respective areas are reviewed. In spite of much progress, we have to further reduce the NO x emission in all the areas. In order to develop more effective technology, the fundamental understanding of the relevant reactions is essential. The heterogeneous reactions, like NO x and N 2 O formation from coal char, NO x and N 2 O reduction with carbon, and NO x reduction with hydrocarbon gases over heterogeneous catalysts are not well understood yet. This paper briefly summarizes our recent studies on the heterogeneous reactions of NO x formation and destruction. The importance of surface nitrogen species is emphasized in all the reaction systems. The presence of such surface species plays a very important role, not only in NO x destruction on carbon surfaces, but also in the NO x release during coal char combustion. Finally, future research areas are identified, where we need to understand what actually happens under high-temperature reaction conditions

    The existing literature generally ascribes the virtual absence of the transport sector from the Clean Development Mechanism (CDM) to the inherent complexity of quantifying emission reductions from mobile sources. We use archival analysis and interviews with CDM decision-makers and experts to identify two additional groups of explanations. First, we show the significance of aspects of the CDM's historical evolution, such as the order in which methodologies were considered and the assignment of expert desk reviewers. Second, we highlight inconsistencies in the treatment of uncertainty across sectors. In contrast to transport methodologies, other sectors are characterized by a narrow focus on sources of measurement uncertainty and a neglect of economic effects ('market leakages'). We do not argue that the rejection of transport methodologies was unjustified, but rather than many of the same problems are inherent in other sectors. Thus, the case of transport sheds light on fundamental problems in quantifying emission reductions under the CDM. We argue that a key theoretical attraction of the CDM-equalization of marginal abatement costs across all sectors-has been difficult to achieve in practice.

    Highlights: • The research focuses on agricultural sectors of the eighteen European countries. • The main drivers of energy-related CO_2 emission are quantified by means of IDA. • The slack-based DEA model is applied to gauge the environmental efficiency. • Shadow prices of carbon emission are analysed. • Energy efficiency remains the primary means for increasing environmental efficiency. - Abstract: Climate change mitigation is a key issue in formulating global environmental policies. Energy production and consumption are the main sources of greenhouse gas (GHG) emissions in Europe. Energy consumption and energy-related GHG emissions from agriculture are an important concern for policymakers, as the agricultural activities should meet food security goals along with proper economic, environmental, and social impacts. Carbon dioxide (CO_2) emission is the most significant among energy-related GHG emissions. This paper analyses the main drivers behind energy-related CO_2 emission across agricultural sectors of European countries. The analysis is based on aggregate data from the World Input-Output Database. The research explores two main directions. Firstly, Index Decomposition Analysis (IDA), facilitated by the Shapley index, is used to identify the main drivers of CO_2 emission. Secondly, the Slack-based Model (SBM) is applied to gauge the environmental efficiency of European agricultural sectors. By applying frontier techniques, we also derive the measures of environmental efficiency and shadow prices, thereby contributing to a discussion on CO_2 emission mitigation in agriculture. Therefore, the paper devises an integrated approach towards analysis of CO_2 emission based upon advanced decomposition and efficiency analysis models. The research covers eighteen European countries and the applied methodology decomposes contributions to CO_2 emission across of regions and factors. Results of IDA suggest that decreasing energy intensity is the main factor

    2014-01-01

    We assess recent Chinese climate policy proposals in a multi-region, multi-sector computable general equilibrium model with a Chinese carbon emissions trading scheme (ETS). When the emissions intensity per GDP in 2020 is required to be 45% lower than in 2005, the model simulations indicate that the climate policy induced welfare loss in 2020, measured as the level of GDP and welfare in 2020 under climate policy relative to their level under business-as-usual (BAU) in the same year, is about 1%. The Chinese welfare loss in 2020 slightly increases in the Chinese rate of economic growth in 2020. When keeping the emissions target fixed at the 2020 level after 2020 in absolute terms, the welfare loss will reach about 2% in 2030. If China's annual economic growth rate is 0.5 percentage points higher (lower), the climate policy-induced welfare loss in 2030 will rise (decline) by about 0.5 percentage points. Full auctioning of carbon allowances results in very similar macroeconomic effects as free allocation, but full auctioning leads to higher reductions in output than free allocation for ETS sectors. Linking the Chinese to the European ETS and restricting the transfer volume to one third of the EU's reduction effort creates at best a small benefit for China, yet with smaller sectoral output reductions than auctioning. These results highlight the importance of designing the Chinese ETS wisely. - Highlights: • 45% Chinese carbon intensity target for 2020 implemented via emissions trading. • 1% GDP/welfare loss in 2020 and 2% in 2030 for a fixed emissions target after 2020. • 0.5 percentage points higher (lower) growth, increases (decreases) climate policy-induced welfare loss in 2030 by about 0.5 percentage points. • Similar macroeconomic effects for free allocation and full auctioning, but higher reductions in output under full auctioning in ETS sectors. • Restricted linking to EU emissions trading creates at best a small benefit for China

    Historically, the bulk production of electricity has been achieved by burning fossil fuels, with unavoidable gaseous emissions, including large quantities of carbon dioxide: an average-sized modern coal-burning power station is responsible for more than 10 Mt of CO(2) each year. This paper details typical emissions from present-day power stations and discusses the options for their reduction. Acknowledging that the cuts achieved in the past decade in the UK CO(2) emissions have been achieved largely by fuel switching, the remaining possibilities offered by this method are discussed. Switching to less-polluting fossil fuels will achieve some measure of reduction, but the basic problem of CO(2) emissions continues. Of the alternatives to fossil fuels, only nuclear power represents a zero-carbon large-scale energy source. Unfortunately, public concerns over safety and radioactive waste have still to be assuaged. Other approaches include the application of improved combustion technology, the removal of harmful gases from power-station flues and the use of waste heat to improve overall power-station efficiency. These all have a part to play, but many consider our best hope for emissions reduction to be the use of renewable energy. The main renewable energy contenders are assessed in this paper and realistic estimates of the contribution that each could provide are indicated. It appears that, in the time-scale envisaged by planners for reduction in CO(2) emission, in many countries renewable energy will be unlikely to deliver. At the same time, it is worth commenting that, again in many countries, the level of penetration of renewable energy will fall short of the present somewhat optimistic targets. Of renewable options, wind energy could be used in the short to medium term to cover for thermal plant closures, but for wind energy to be successful, the network will have to be modified to cope with wind's intermittent nature. Globally, hydroelectricity is currently the

    In France an objective of dividing greenhouse gas emissions by four, from the 1990 level, by 2050 has been set. Are these ambitions out of our reach? What will the price to pay for this objective be? We have built a long-term back-casting transport demand model (TILT, Transport Issues in the Long Term) . This model is centered on defined behavior types - in which the speed-GDP elasticity plays a key role - in order to determine demand estimations. This model lets us understand past tendencies - the coupling between growth and personal and freight mobility and adapt behavioral hypothesis - linked to the evolution of public policies - in order to show how a 75% reduction objective can be attained. The main results are an estimation of CO 2 emissions for the transport sector taking into account technical progress and demand. These results are presented as three scenario families named: Pegasus, Chronos and Hestia. Each family corresponds to a growing degree of constraint on mobility. It is possible to divide greenhouse gas emissions in the transport sector by four. Technical progress is able to lead to more than half of these reductions. The interest of these scenarios is to show that there exist different paths - through organizational change - to getting the other half of the reductions. (author)

    Full Text Available Cerium oxide being a rare earth metal with dual valance state existence has exceptional catalytic activity due to its oxygen buffering capability, especially in the nanosized form. Hence when used as an additive in the diesel fuel it leads to simultaneous reduction and oxidation of nitrogen dioxide and hydrocarbon emissions, respectively, from diesel engine. The present work investigates the effect of cerium oxide nanoparticles on performance and emissions of diesel engine. Cerium oxide nanoparticles were synthesized by chemical method and techniques such as TEM, EDS, and XRD have been used for the characterization. Cerium oxide was mixed in diesel by means of standard ultrasonic shaker to obtain stable suspension, in a two-step process. The influence of nanoparticles on various physicochemical properties of diesel fuel has also been investigated through extensive experimentation by means of ASTM standard testing methods. Load test was done in the diesel engine to investigate the effect of nanoparticles on the efficiency and the emissions from the engine. Comparisons of fuel properties with and without additives are also presented.

    The contribution of aviation to global carbon dioxide (CO{sub 2}) emissions is projected to triple by 2050. As nations strive to meet CO{sub 2} reduction targets, policy interventions to manage the growth of emissions arising from air travel are likely. Here, we investigate the potential influence of aviation emissions reduction policies on the business travel patterns of individual corporations. Using travel data from six UK-based companies, we find that increased ticket prices can deliver substantial emissions cuts, particularly on premium class flights, and may provide strong financial incentives to seek modal and/or technological alternatives to flying. We also find that corporations from different business sectors vary in their responsiveness to a range of policy options. Finally, we examine questionnaire data to determine whether companies more broadly are going beyond compliance to mitigate their environmental impact by managing travel-related emissions voluntarily. Although many corporations are measuring and reporting emissions, only a limited number are willing to implement in-house reduction policies prior to regulation. (author)

    This study offers insights about the design of economically efficient policies to curb carbon dioxide (CO{sub 2}) emissions in Switzerland. The method uses MARKAL, a bottom-up engineering model of the energy system. Based on a stochastic programming approach, this study proposes as a first option the introduction of a hedging carbon tax. Using then a multinational MARKAL model, this study considers as a second alternative an international co-operation to curb jointly CO{sub 2} emissions by means of a uniform carbon tax.

    Observed acoustic power in magnetic regions is lower than the quiet Sun because of absorption, emissivity reduction, and local suppression of solar acoustic waves in magnetic regions. In the previous studies, we have developed a method to measure the coefficients of absorption, emissivity reduction, and local suppression of sunspots. In this study, we go one step further to measure the spatial distributions of three coefficients in two active regions, NOAA 9055 and 9057. The maps of absorption, emissivity reduction, and local suppression coefficients correlate with the magnetic map, including plage regions, except the emissivity reduction coefficient of NOAA 9055 where the emissivity reduction coefficient is too weak and lost among the noise.

    Full Text Available Carbon emissions from the construction material industry have become of increasing concern due to increasingly urbanization and extensive infrastructure. Faced with serious atmospheric deterioration, governments have been seeking to reduce carbon emissions, with carbon trading and carbon taxes being considered the most effective regulatory policies. Over time, there has been a global consensus that integrated carbon trading/carbon tax policies are more effective in reducing carbon emissions. However, in an integrated carbon reduction policy framework, balancing the relationship between emission reductions and low-carbon benefits has been found to be a critical issue for governments and enterprises in both theoretical research and carbon emission reduction practices. As few papers have sought to address these issues, this paper seeks to reach a trade-off between economic development and environmental protection involving various stakeholders: regional governments which aim to maximize social benefits, and producers who seek economic profit maximization. An iterative interactive algorithmic method with fuzzy random variables (FRVs is proposed to determine the satisfactory equilibrium between these decision-makers. This methodology is then applied to a real-world case to demonstrate its practicality and efficiency.

    2015-08-01

    Full Text Available Greenhouse gas emissions have serious impacts on the natural environment. Therefore, the restrictions imposed on carbon emission force enterprises to take carbon emission into consideration when making production decisions. In this paper, in the context of allowing emission trading and investment of emission reduction technology, models were presented for a two-stage supply chain to analyze the optimal investment and pricing decisions. The results indicate that manufacturer’s endurance capacity of reduction difficulty is higher in the cooperation model than in the Stackelberg game model, and that perfect coordination of supply chains can be realized by a revenue sharing contract. From the perspective of a consumer, low-carbon products mean higher price, so that subsidies or tax exemptions should be provided to keep low prices. Meanwhile, the government can promote investment in emission-reduction technologies and achieve its emission reduction targets by controlling emission trading price, strengthening emission reduction publicity and providing technology investment subsidies.

    The initial years of the European Union's Emissions Trading System (EU ETS) have provided a large-scale testing ground for trading of a new environmental commodity, carbon dioxide. This paper provides an overview of the origins and characteristics of the EU ETS. It then goes on to analyse the most contentious issues that have been discussed in the economics literature and in the public debate surrounding the trading system. The lessons learned are diverse and not all experiences are positive. Nevertheless, invaluable information has been gained from the EU ETS and policy makers in Europe and elsewhere would be wise to make use of it, be they supporters of emissions trading or sceptics to such policies. The paper concludes with a look toward the future, highlighting some upcoming revisions of the EU ETS and at what issues remain unresolved

    Climate change has become one of the most challenging issues facing the world. Chinese government has realized the importance of energy conservation and prevention of the climate changes for sustainable development of China's economy and set targets for CO_2 emissions reduction in China. In China industry contributes 84.2% of the total CO_2 emissions, especially manufacturing industries. Data envelopment analysis (DEA) and Malmquist productivity (MP) index are the widely used mathematical techniques to address the relative efficiency and productivity of a group of homogenous decision making units, e.g. industries or countries. However, in many real applications, especially those related to energy efficiency, there are often undesirable outputs, e.g. the pollutions, waste and CO_2 emissions, which are produced inevitably with desirable outputs in the production. This paper introduces a novel Malmquist–Luenberger productivity (MLP) index based on directional distance function (DDF) to address the issue of productivity evolution of DMUs in the presence of undesirable outputs. The new RAM (Range-adjusted measure)-based global MLP index has been applied to evaluate CO_2 emissions reduction in Chinese light manufacturing industries. Recommendations for policy makers have been discussed. - Highlights: •CO_2 emissions reduction in Chinese light manufacturing industries are measured. •A novel RAM based Malmquist–Luenberger productivity index has been developed. •Recommendation to policy makers for reducing CO_2 reduction in China are given.

    No-one any longer calls into question the latest IPCC report which emphasises the urgent need to take action to avoid the worst in terms of climate change. IPCC's Working Group II firstly shows that if the global average temperature in the atmosphere rises 2.5-3 deg. C above pre-industrial levels, there is a strong risk that irreversible impacts (melting of permafrost, highly reduced role of forest cover and oceans as carbon sinks), and thus unavoidable climate change, will occur. For this reason, regions such as Europe have set a target of a maximum 2 deg. C global temperature increase. But what does such a target mean in terms of greenhouse gas (GHG) concentrations and emissions? This question can be answered in part by comparing many scenarios defined by the IPCC. This exercise shows that the only reasonable chance of statistically reaching the '2 deg. C' constraint is if humanity manages to stabilize concentrations of all GHGs between 400 and 450 ppmv CO 2 eq in the long term. However, the analysis also highlights that if GHG concentrations go significantly beyond this target threshold at any time in the intermediate period between 2020 and 2100 (above 475 to 500 ppmv), it is likely that it would become impossible to reach the target at all. CO 2 emissions more or less hold policy-makers' full attention. CO 2 effectively accounts for 77% of total emissions and it is the GHG with the most rapidly increasing emissions. The logical conclusion drawn is that priority action must be taken to reduce CO 2 emissions. However, it is necessary to analyse this in greater detail if we are to assess the real climate impacts of the different GHGs at different time horizons and particularly in 2030-2050, since this is the time horizon that holds policy-makers' attention. In particular, methane reduction measures, whatever their dynamics may be, are far from being marginal compared to those that can be implemented solely to reduce CO 2 emissions. This analysis shows that the

    Full Text Available China is a country with substantial differences in economic development, energy consumption mix, resources, and technologies, as well as the development path at the provincial level. Therefore, China’s provinces have different potential and degrees of difficulty to carry out carbon emission reduction (CER requirements. In addition, interprovincial trade, with a large amount of embodied carbon emissions, has become the fastest growing driver of China’s total carbon emissions. A reasonable CER allocation plan is, therefore, crucial for realizing the commitment that China announced in the Paris Agreement. How to determine a fair way to allocate provincial CER duties has become a significant challenge for both policy-makers and researchers. In this paper, ecological network analysis (ENA, combined with a multi-regional input-output model (MRIO, is adopted to build an ecological network of embodied emissions across 30 provinces. Then, by using flow analysis and utility analysis based on the ENA model, the specific relationships among different provinces were determined, and the amount of responsibility that a certain province should take quantified, with respect to the embodied carbon emission (ECE flows from interprovincial trade. As a result, we suggest a new CER allocation plan, based on the detailed data of interprovincial relationships and ECE flows.

    Atmospheric pollution emissions have become a matter of public concern in recent years. However, most of the existing researches on NOx pollution are from the natural science and technology perspective, few studies have been conducted from an economic point, and regional differences have not been given adequate attention. This paper adopts provincial panel data from 2006 to 2013 and the LMDI model to analyze the key driving factors and regional dilemmas of NOx emissions. The results show that significant regional disparities still exit on NO x emissions and its reduction effect 27 provinces didn't accomplish their corresponding reduction targets. Economic development factor is the dominating driving factor of NO x emissions during the study period, while energy efficiency and technology improvement factors offset total NO x emissions in the majority of provinces. In addition, the industrial structure factor plays a more significant role in reducing the NO x emissions after 2011. Therefore, the government should consider all these factors as well as regional heterogeneity in developing appropriate pollution mitigating policies. It's necessary to change NOx emissions control attitude from original key areas control to divided-zone control, not only attaches great importance to the reduction of the original key areas, but also emphasizes the new potential hotspots with high NO x emissions.

    This paper estimates the future greenhouse gas (GHG) and local pollutant emissions for India under various scenarios. The reference scenario assumes continuation of the current official policies of the Indian government and forecasts of macro-economic, demographic and energy sector indicators. Other scenarios analyzed are the economic growth scenarios (high and low), carbon mitigation scenario, sulfur mitigation scenario and frozen (development) scenario. The main insight is that GHG and local pollutant emissions from India, although connected, do not move in synchronization in future and have a disjoint under various scenarios. GHG emissions continue to rise while local pollutant emissions decrease after some years. GHG emission mitigation therefore would have to be pursued for its own sake in India. National energy security concerns also favor this conclusion since coal is the abundant national resource while most of the natural gas has to be imported. The analysis of contributing factors to this disjoint indicates that sulfur reduction in petroleum oil products and penetration of flue gas desulfurisation technologies are the two main contributors for sulfur dioxide (SO2) mitigation. The reduction in particulate emissions is mainly due to enforcing electro-static precipitator efficiency norms in industrial units, with cleaner fuels and vehicles also contributing substantially. These policy trends are already visible in India. Another insight is that high economic growth is better than lower growth to mitigate local pollution as lack of investible resources limits investments in cleaner environmental measures. Our analysis also validates the environmental Kuznets' curve for India as SO2 emissions peak around per capita GDP of US$ 5,300-5,400 (PPP basis) under various economic growth scenarios.

    An international symposium on the reduction of emissions and geological storage of CO 2 was held in Paris from 15 to 16 September 2005. The event, jointly organized by IFP, ADEME and BRGM, brought together over 400 people from more than 25 countries. It was an opportunity to review the international stakes related to global warming and also to debate ways of reducing CO 2 emissions, taking examples from the energy and transport sectors. The last day was dedicated to technological advances in the capture and geological storage of CO 2 and their regulatory and economic implications.

    Growing global concern regarding climate change motivates technological studies to minimize environmental impacts. In this context, solar water heating (SWH) systems are notably prominent in Brazil, primarily because of the abundance of solar energy in the country. However, SWH designs have not always been perfectly developed. In most projects, the installation option of the solar system only considers the electric power economy aspects and not the particular characteristics of each climatic zone. Thus, the primary objective of this paper is to assess the potential of carbon dioxide reduction with the use of SWH in comparison with electric showers in social housing in several Brazilian climatic zones. The Brazilian government authorities have created public policies to encourage the use of these technologies primarily among the low-income population. The results of this paper indicate that hot climactic regions demonstrate a low reduction of CO 2 emissions with SWH installations. Thus, solar radiation is not useful for water heating in those regions, but it does lead to a large fraction of household cooling loads, implying a demand for electrical energy for air conditioning or requiring the adoption of passive techniques to maintain indoor temperatures below threshold values. -- Graphical abstract: Display Omitted -- Highlights: •Brazil has created public policies to increase the use of solar water heating in social housing. •We have evaluated the potential for reduction of CO 2 emissions installing solar water heating. •We have found that the coldest regions have the greatest potential for reducing emissions. •Passive technologies for thermal comfort in hot climate households are more useful than solar water heating systems

    Highlights: ► We evaluate energy and carbon equivalence from CPO production based on a CBM. ► Energy spent and produced via carbon movement from palm oil mill was determined. ► Scenarios were formulated to evaluate the potential reduction of carbon emission. ► Utilization of biomass from palm oil mill shows the high potential of C-reduction. -- Abstract: This study aimed to evaluate energy and carbon equivalences (CE) associated with palm oil milling and to evaluate sustainability alternatives for energy consumption. Appropriate ways to reduce carbon emissions were also evaluated. A field survey was carried out to quantify the input and output of energy and materials following the conceptual framework of a carbon-balanced model (CBM), which exclude other non-CO 2 greenhouse gases. Survey results indicate that the electrical energy consumption for daily mill start-up averaged 18.7 ± 5.4 kWh/ton Fresh Fruit Bunches (FFBs). This energy is equivalent to 114.4 ± 33.2 kWh/ton Crude Palm Oil (CPO) which was found to be offset by that generated in the mills using palm fiber as a solid fuel. Currently, organic residues contained in the wastewater are anaerobically converted to methane. The methane is used as fuel to generate electricity and sold to an outside grid network at a generation rate of 8.1 ± 2.1 kWh/ton FFB. Based on the CBM approach, carbon emissions observed from the use of fossil energy in palm oil milling were very small; however, total carbon emission from oil palm plantation and palm oil milling were found to be 12.3 kg CE/ton FFB, resulting in the net carbon reduction in CPO production of 2.8 kg CE/ton FFB or 53.7 kg CE/ha-y. Overall, the sum of C-reduction was found 1.2 times greater than that of C-emission. This figure can be increased up to 5.5, if all biomass by-products are used as fuel to generate electricity only. The full potential for carbon reduction from palm oil milling is estimated at 0.94 kW of electric power for every hectare of

  17. What is a fair CO2 tax increase? On fair emission reductions in the transport sector

    We examine how individual preferences for fair reductions of carbon dioxide (CO 2 ) emissions affect the support for increases in the CO 2 tax on gasoline and diesel. We assume that people not only care about their own material welfare, but also have preferences for fairness in policy design, and we explore the implications using original data from a mail questionnaire sent to a representative sample of the Swedish population. The main result is that fairness in policy design does matter. Those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the CO 2 tax. One possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of CO 2 reductions. Via a split sample analysis, we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not. This sheds light on the potential goal conflict between the importance of fairness principles and self-interest in the form of a need for private car transportation. (author)

  18. Technologies for the Reduction of Nitrogen Oxides Emissions

    Full Text Available When it comes to gas turbines, their main problem concerning pollutant emissions is represented by nitric oxides. Among other emissions, sulphur oxides being much reduced due to the use of liquid distilled and gas fuels with a low content of sulphur. Using water or steam injection became the favourite method during the '80s and especially the '90s since "dry" methods and catalytic reduction were both at the beginning of the development phase. Catalytic convertors have been used since the '80s and they are still used although the costs of renewing the catalyst are very high. In the last twenty years a gradual decrease has been registered on the limits of nitric oxides from 75 ppm to 25 ppm, and now the target is oriented towards the 9 ppm level. The evolution of burning technologies of combustion makes it possible to control the level of production of nitric oxides even from the source without being necessary to use "humid" methods. This, of course, opened the market for gas turbines because they can function even in areas with limited quality water reserves, such as maritime platforms and in the desert. In this paper, we are going to show that, although water injection is still used, "dry" control technologies of burning became favourite methods for the majority of users on the industrial power generators market. The great dependency between the creation of nitric oxides and the temperature reveals the effect of direct water or steam injection on reducing nitric oxides. Recent research showed that a reduction up to 85% of nitric oxides may be obtained by using the water or steam injection all together with the improvement of aerodynamic character of the burning room.

    During the last few decades, traffic injuries have become one of the leading causes of death and disability in the world. In urban areas, traffic congestion, noise, and emissions from motor vehicles produce subjective disturbances and detectable pathological effects. More than one billion people are exposed to harmful levels of environmental pollution. Because its combustion engine generates carbon dioxide (CO2), the automobile is one of the chief sources of the gases that are causing the greenhouse effect. The latter has already caused a rise in the average ambient temperature, and over the next decades it will predictable cause significant climatic changes whose consequences, though uncertain, are likely to be harmful and possibly catastrophic. Aside from the greenhouse effect, the relentless growth of parking zones, traffic, and the roadway infrastructure in urban and rural areas is currently one of the leading causes of environmental degradation. Urban development, which is nearly always "planned" around traffic instead of people, leads to a significant deterioration in the quality of life, while it also destroys the social fabric. Unlike the private automobile, public transportation, bicycles, and walking help reduce pollution, congestion, and traffic volume, as well as the morbidity and mortality resulting from injuries and ailments related to pollution. Non-automobile transportation also encourages physical activity--with its positive effect on general health--and helps reduce the greenhouse effect. The drop in traffic volume and the increased use of alternate means of transportation are thus an integrated health promotion policy which should become an inherent part of the movement for the promotion of healthy cities and of transportation policies and economic policy in general.

    Nitrous oxide originates primarily from natural biogeochemical processes, but its atmospheric concentrations have been strongly affected by human activities. According to IPCC, it is the third largest contributor to the anthropogenic greenhouse gas emissions (after carbon dioxide and methane). Deep decarbonization scenarios, which are able to constrain global temperature increase within 1.5°C, require strategies to cut methane and nitrous oxide emissions on top of phasing out carbon dioxide emissions. Employing the Greenhouse gas and Air pollution INteractions and Synergies (GAINS) model, we have estimated global emissions of nitrous oxide until 2050. Using explicitly defined emission reduction technologies we demonstrate that, by 2030, about 26% ± 9% of the emissions can be avoided assuming full implementation of currently existing reduction technologies. Nearly a quarter of this mitigation can be achieved at marginal costs lower than 10 Euro/t CO2-eq with the chemical industry sector offering important reductions. Overall, the largest emitter of nitrous oxide, agriculture, also provides the largest emission abatement potentials. Emission reduction may be achieved by precision farming methods (variable rate technology) as well as by agrochemistry (nitrification inhibitors). Regionally, the largest emission reductions are achievable where intensive agriculture and industry are prevalent (production and application of mineral fertilizers): Centrally Planned Asia including China, North and Latin America, and South Asia including India. Further deep cuts in nitrous oxide emissions will require extending reduction efforts beyond strictly technological solutions, i.e., considering behavioral changes, including widespread adoption of "healthy diets" minimizing excess protein consumption.

    2015-01-01

    Energy saving and carbon dioxide emission reduction in China is attracting increasing attention worldwide. At present, China is in the phase of rapid urbanization and industrialization, which is characterized by rapid growth of energy consumption. China's transport sector is highly energy-consuming and pollution-intensive. Between 1980 and 2012, the carbon dioxide emissions in China's transport sector increased approximately 9.7 times, with an average annual growth rate of 7.4%. Identifying the driving forces of the increase in carbon dioxide emissions in the transport sector is vital to developing effective environmental policies. This study uses Vector Autoregressive model to analyze the influencing factors of the changes in carbon dioxide emissions in the sector. The results show that energy efficiency plays a dominant role in reducing carbon dioxide emissions. Private vehicles have more impact on emission reduction than cargo turnover due to the surge in private car population and its low energy efficiency. Urbanization also has significant effect on carbon dioxide emissions because of large-scale population movements and the transformation of the industrial structure. These findings are important for the relevant authorities in China in developing appropriate energy policy and planning for the transport sector. - Highlights: • The driving forces of CO 2 emissions in China's transport sector were investigated. • Energy efficiency plays a dominant role in reducing carbon dioxide emissions. • Urbanization has significant effect on CO 2 emissions due to large-scale migration. • The role of private cars in reducing emissions is more important than cargo turnover

  2. Contingency planning for rapid reduction of greenhouse gas emissions

    2010-03-01

    Full Text Available The current and predicted levels of greenhouse gas (GHG emissions are, according to the best international scientific estimates, leading the world towards climate change that will have serious consequences for all countries. The problem is aggravated by the tendency of people and institutions not to take action until catastrophic consequences emerge. The history of crises in other sectors show us that reactions are likely to focus on ad-hoc reactions or using plans that are readily available, with negative results. However, the alternative of developing public plans for drastic and rapid reductions is not likely to gain support because of their radical nature. The author therefore proposes that large organizations with direct or indirect control over substantial GHG emissions should prepare private contingency plans for very rapid reductions in emissions, so that more rational and less destructive plans will be available when the appropriate moment comes for last-minute action. Examples of the type of specific plans that may be appropriate are suggested.

    Según las estimaciones científicas internacionales más optimistas, los niveles actuales y previstos de emisiones de gases de efecto invernadero (GEI están llevando al mundo hacia un cambio climático que tendrá graves consecuencias para todos los países. El problema se ve agravado por la tendencia de personas e instituciones a no tomar medidas hasta que no se perciben las catastróficas consecuencias. El historial de crisis ocurridas en otros sectores nos demuestra que las reacciones probablemente se centren en medidas ad hoc o en emplear planes que ya existían, pero sin resultados. Sin embargo, es poco probable que la alternativa al desarrollo de planes públicos para las reducciones drásticas y rápidas consiga el apoyo necesario, debido precisamente a su radicalidad. El autor recomienda por tanto que las grandes organizaciones que tengan control directo o indirecto sobre un

    The economic impacts on developing regions following a global cap and trade system for carbon dioxide are assessed through the use of an energy-economy systems model. Both an equal per capita allocation and a contraction and convergence allocation with convergence of the per capita emissions by 2050 are shown to offer economic incentive for Africa, India and probably also Latin America to accept binding emissions commitments under a 450 ppm carbon dioxide stabilization scenario. The gain for Latin America is mainly a result of increased export revenues from sales of bio-fuels as a result of the climate policy. It is, on the other hand, unlikely that these allocation approaches would offer an economic incentive for China to join the regime because of its high economic growth, present higher per capita emissions than India and Africa, and more costly mitigation options than Latin America. A more stringent allocation for developing countries such as contraction with convergence of the per capita emissions by the end of this century is estimated to generate reduced net gains or increased net losses for the developing regions (though Africa is still expected to gain)

    Energy and environmental issues have recently aroused increasing interest in China and many approaches are used to evaluate energy and environmental performance. In this paper, a two-stage network DEA framework is applied to evaluate the efficiency of energy saving and emission reduction in China during the period of the eleventh five-year plan, from 2006 to 2010. In this study, economic activities are divided into production and treatment processes. This is different from previous research which generally focused on either environmental efficiency or energy efficiency, omitting the integration of energy and environmental measures. Today, energy saving and emission reduction are both parts of the basic state policy of China and are equally important. The empirical results in this study show that: (i) eastern China has the best energy saving and emission reduction efficiency, performing is better than western and central China. (ii) The efficiency of the production process in central China is better than that in western China while the western area performs better than the central area in term of treatment efficiency. (iii) Integrated efficiency of energy saving and emission reduction of China was relatively stable in the five years and the pollution treatment efficiency maintained a rising trend. -- Highlights: •We measured China's regional energy saving and emission reduction efficiency using two-stage DEA approach. •The production and treatment processes are incorporated in evaluation. •Eastern China performs best in terms of energy saving and emission reduction efficiency. •Integrated efficiency of energy saving and emission reduction of China kept a stable trend during 2006–2010

  5. Evaluation of policy options to reform the EU Emissions Trading System. Effects on carbon price, emissions and the economy

    The EU Emissions Trading System (EU ETS) is a key instrument of EU climate policy, providing a clear reduction pathway for CO2 emissions. The current carbon price (of about 3 euros per tonne of CO2, April 2013) is much lower than previously expected (which was around 30 euros) and is likely to remain low for a long time. This fuels doubts about whether the ETS will remain a key policy instrument in the long term. Such doubts also increase investment uncertainty, which is likely to have a negative impact on further investments in low-carbon technologies needed for a low-carbon economy in 2050. In November 2012, the European Commission put forward six options for a more structural reform of the EU ETS. The proposed options vary from reducing the cap and expanding the ETS to include other sectors, to strengthening the ETS by measures directly affecting allowance prices. The Dutch Ministry of Infrastructure and the Environment (IenM) asked the PBL Netherlands Environmental Assessment Agency to assess the impact of these options. Four categories of options for reforming the ETS were evaluated: (1) reducing the supply of emission allowances; (2) expanding the ETS by including other sectors; (3) a minimum price for auctioned allowances; and (4) combining ETS with a carbon tax. Recently, the European Parliament voted against the European Commission's proposal to temporarily set aside emission allowances. In an earlier assessment of this proposal, PBL concluded that the impact of this backloading proposal on CO2 prices is likely to be limited, because the total amount of allowances up to 2020 would remain unchanged. All options analysed would reduce emissions and cause the emission price to increase. A minimum price on carbon, however, would provide the best opportunity to make the ETS more robust against unforeseen events, such as a further deterioration of the economy. Such a minimum price would result in more emission reductions if abatement proves to be cheaper

    Hopes are high that removing fossil fuel subsidies could help to mitigate climate change by discouraging inefficient energy consumption and levelling the playing field for renewable energy. In September 2016, the G20 countries re-affirmed their 2009 commitment (at the G20 Leaders’ Summit) to phase out fossil fuel subsidies and many national governments are using today’s low oil prices as an opportunity to do so. In practical terms, this means abandoning policies that decrease the price of fossil fuels and electricity generated from fossil fuels to below normal market prices. However, whether the removal of subsidies, even if implemented worldwide, would have a large impact on climate change mitigation has not been systematically explored. Here we show that removing fossil fuel subsidies would have an unexpectedly small impact on global energy demand and carbon dioxide emissions and would not increase renewable energy use by 2030. Subsidy removal would reduce the carbon price necessary to stabilize greenhouse gas concentration at 550 parts per million by only 2-12 per cent under low oil prices. Removing subsidies in most regions would deliver smaller emission reductions than the Paris Agreement (2015) climate pledges and in some regions global subsidy removal may actually lead to an increase in emissions, owing to either coal replacing subsidized oil and natural gas or natural-gas use shifting from subsidizing, energy-exporting regions to non-subsidizing, importing regions. Our results show that subsidy removal would result in the largest CO2 emission reductions in high-income oil- and gas-exporting regions, where the reductions would exceed the climate pledges of these regions and where subsidy removal would affect fewer people living below the poverty line than in lower-income regions.

    A range of policies have been implemented in the agricultural, transportation, and electric power sectors, which comprise the majority of GHG emissions in the US. Two prominent policy sets are the national RFS and state-level RPSs. The purpose of this research is to examine the GHG implications of the state RPSs and their welfare costs of mitigating GHG emissions. We also analyze the interactions between the RFS and state RPS policies and the extent to which these policies create competition ...

    Climate change remains one of the biggest threats to life on earth to date with black carbon (BC) emissions or smoke being the strongest cause after carbon dioxide (CO 2 ). Surprisingly, scientific evidence about black carbon emissions reduction in healthcare settings is sparse. This paper presents new research findings on the reduction of black carbon emissions from an observational study conducted at the UN Peacekeeping Operations (MINUSTAH) in Haiti in 2014. Researchers observed 20 incineration cycles, 30 minutes for each cycle of plastic and cardboard sharps healthcare waste (HCW) containers ranged from 3 to 14.6 kg. The primary aim was to determine if black carbon emissions from healthcare waste incineration can be lowered by mainstreaming the use of cardboard sharps healthcare waste containers instead of plastic sharps healthcare waste containers. Similarly, the study looks into whether burning temperature was associated with the smoke levels for each case or not. Independent samples t-tests demonstrated significantly lower black carbon emissions during the incineration of cardboard sharps containers (6.81 ± 4.79% smoke) than in plastic containers (17.77 ± 8.38% smoke); a statistically significant increase of 10.96% smoke (95% Confidence Interval ( CI) [4.4 to 17.5% smoke], p = 0.003). Correspondingly, lower bottom burner temperatures occurred during the incineration of cardboard sharps containers than in plastic (95% Cl [16 to 126°C], p = 0.014). Finally, we expect the application of the new quantitative evidence to form the basis for policy formulation, mainstream the use of cardboard sharps containers and opt for non-incineration disposal technologies as urgent steps for going green in healthcare waste management.

    Livestock husbandry in the U.S. significantly contributes to many environmental problems, including the release of methane, a potent greenhouse gas (GHG). Anaerobic digesters (ADs) break down organic wastes using bacteria that produce methane, which can be collected and combusted to generate electricity. ADs also reduce odors and pathogens that are common with manure storage and the digested manure can be used as a fertilizer. There are relatively few ADs in the U.S., mainly due to their high capital costs. We use the MIT Emissions Prediction and Policy Analysis (EPPA) model to test the effects of a representative U.S. climate stabilization policy on the adoption of ADs which sell electricity and generate methane mitigation credits. Under such policy, ADs become competitive at producing electricity in 2025, when they receive methane reduction credits and electricity from fossil fuels becomes more expensive. We find that ADs have the potential to generate 5.5% of U.S. electricity.

    We investigate the incentives for subcontractors (couriers) of a transport and logistics company to report about their CO 2 emissions and to implement CO 2 reducing technologies. Furthermore, we try to find out whether these incentives differ between British and Dutch couriers. We find that several incentives play a significant role. Subcontractors in the Netherlands predominantly are extrinsically motivated to engage in CO 2 reporting and reduction techniques. This is because they are mainly driven by regulatory compliance, energy costs and implementation costs. In contrast, British subcontractors are much more intrinsically motivated to comply. They are predominantly driven by energy costs, environmental awareness, relationship building and reputation building. The contractor will have to account for these differences in making its policies work. - Research highlights: → We investigate incentives for couriers to report CO 2 emissions and to implement CO 2 reduction techniques. → We compare couriers in the Netherlands and the United Kingdom. → Several incentives are significant for the adoption of CO 2 reporting and reduction measures. → There are significant differences in the sensitivity for incentives in the Netherlands and the UK.

  12. Evaluating the CO 2 emissions reduction potential and cost of power sector re-dispatch

    Steinberg, Daniel C.; Bielen, David A.; Townsend, Aaron

    2018-01-01

    Prior studies of the U.S. electricity sector have recognized the potential to reduce carbon dioxide (CO2) emissions by substituting generation from coal-fired units with generation from under-utilized and lower-emitting natural gas-fired units; in fact, this type of 're-dispatch' was invoked as one of the three building blocks used to set the emissions targets under the Environmental Protection Agency's Clean Power Plan. Despite the existence of surplus natural gas capacity in the U.S., power system operational constraints not often considered in power sector policy analyses, such as transmission congestion, generator ramping constraints, minimum generation constraints, planned and unplanned generator outages, and ancillary service requirements, could limit the potential and increase the cost of coal-to-gas re-dispatch. Using a highly detailed power system unit commitment and dispatch model, we estimate the maximum potential for re-dispatch in the Eastern Interconnection, which accounts for the majority of coal capacity and generation in the U.S. Under our reference assumptions, we find that maximizing coal-to-gas re-dispatch yields emissions reductions of 230 million metric tons (Mt), or 13% of power sector emissions in the Eastern Interconnection, with a corresponding average abatement cost of $15-$44 per metric ton of CO2, depending on the assumed supply elasticity of natural gas.

    China's manufacturing industries are traditionally energy-intensive sectors and are responsible for over half of the country's total CO_2 emissions. In this paper, we propose a global meta-frontier non-radial directional distance function approach to measure the CO_2 emissions performance of Chinese manufacturing sectors during the period of 1990–2012. This approach allows us to simultaneously consider technological heterogeneity in manufacturing, non-radial slacks, and undesirable outputs. The global level of environmental technology is incorporated into the efficiency model to improve discriminating power and comparability. The results indicate significant differences in CO_2-emissions-reduction performance among five broad groups of Chinese manufacturing industries. The “global technologies/ innovators group” is the most efficient under meta-frontier technologies, with the smallest technology gap. Meanwhile, the “energy-/resource-intensive commodities group” is, on average, the least efficient. Therefore, the Chinese government should implement targeted policies that encourage firms in the global technologies/innovators group to increase market share while supporting those in the energy-/resource-intensive commodities group to upgrade their technologies. - Highlights: • Global meta-frontier non-radial directional distance function approach is proposed. • It measures CO_2 emissions performance of Chinese manufacturing during 1990–2012. • The impact of group heterogeneity is incorporated. • Global technologies/innovators group is the most efficient under meta-frontier. • Energy-/resource-intensive commodities group is, on average, the least efficient.

    The issue of emissions trading as a viable tool to reduce greenhouse gas emissions by developed countries was discussed. The essence of this author's argument was that emissions trading alone will not solve the climate change problem and that the details of the program are hazy at best. In order to have any hope of meeting the emission reductions, it is essential to begin working out the details now, and to coordinate them with the Clean Development Mechanism (CDM) and Joint Implementation (JI) plan since all three of these flexibility mechanisms will be working in and among themselves, therefore they need to be consistent. Work on a general set of draft principles by the International Climate Change Partnership (ICCP), a coalition headquartered in Washington, DC, was summarized. Essentially, ICCP favors voluntary programs, incentives for participation, no quantitative limits on trading, no limits on sources and sinks. ICCP believes that trading should be allowed at the company level, and liability should not devolve on the buyer alone, rather, it should be negotiated between buyers and sellers. Credits for early action should also be tradable and most of all, the trading program should be simple to allow active participation by industry, and be free of bureaucratic impediments

    Carbon emission reduction schemes by improving residential building energy performance are often developed and assessed upon the assumption of current or stationary climates. This study investigated the heating and cooling (H-C) energy requirements and corresponding carbon emissions of residential houses in different climatic conditions in relation to global warming. This included assessing and quantifying the efficacy of emission reduction schemes based on emission reduction capacity (ERC). ERC represents the percentage of projected carbon emission reduction under changing climate in a specific year compared to the expected reduction by a scheme at current or stationary climates. It is shown that in a heating-dominated region with a cold climate or temperate climate with cold winter, ERC is projected to increase (or the projected emission reduction is higher than the expected reduction under the emission reduction scheme) in the presence of global warming. In contrast, in a cooling-dominated region with a hot dry or hot humid climate or an H-C balanced temperate climate, ERC is projected to decline. This implies that emission reductions will be lower than those initially targeted by the emission reduction scheme without consideration of global warming. Additionally, to reflect the changing carbon emission over years due to climate change, the average emission reduction capacity (AERC) was also proposed for the assessment of reduction schemes. It was concluded that the design and assessment of carbon emission reduction schemes for residential buildings need to move beyond its assumptions of a current or stationary climate to take into account climate change impacts.

    Described herein are the FY 2000 results of the survey on policies for reducing the greenhouse gas emissions. For Japan to meet the emission reduction targets stated in the Kyoto Protocol, it is necessary to examine in detail what the most desirable policy measures should be for each sector. In this context, it is also essential to determine particular features of the various policies that may include action plans, environment taxes, and emission trading in addition to conventional regulations and subsidy measures, and to assess their anticipated effects and problems. After examining the policies adopted by various countries to reduce greenhouse gas emissions, this study has attempted to identify the merits and demerits of the various emission reduction policies and to present a systematic account of progress achieved in Japan during basic investigations into this issue. This reports provides a systematic overview of the action plans adopted by the other major countries to prevent global warming and makes a comparative study of the contents of the policies that have been introduced by these countries; identifies the arguments raised in the overseas debates on the effects and problems of global warming prevention policies, and attempts to put the arguments into some systematic order; examines the statuses of the current progress made by various countries with regard to methane and N{sub 2}O emission reduction policies, and discusses the related problems; gives a systematic account of how the policy options are being scrutinized by the government as the base for studying the policy mix for Japan; and examines statuses of the current progress made by Japan with regard to methane and N{sub 2}O emission reduction policies.

    Involved into the research project ''Mitigation of greenhouse gas emissions in oilseed rape cropping with special consideration of nitrogen fertilizing'' regional specific GHG cropping emissions according to benchmark and regional experts are calculated by using a calculation method developed in cooperation with IFEU and according to IPCC (2006). The following results are achieved for 35 German NUTS2-regions: - nitrogen fertilization is the main influence for GHG emission reduction; - the use of low-emission nitrogen fertilizers is worth for GHG emission reduction; - without increasing the nutrient efficiency of organic fertilizers, GHG emission reductions are difficult to achieve in many regions; - GHG emission reduction/climate protection and realization of the WRRL or N-Saldo reduction come up to the same aim; - economic consequences of restrictive carbon mitigation can be compensated by slight price surcharges for certified raw material.

    In recognizing that energy markets and greenhouse gas emissions are significantly influences by local factors, this research examines opportunities for achieving realistic energy greenhouse gas emissions from U.S. cities through provisions of more sustainable infrastructure. Greenhouse gas reduction opportunities are examined through the lens of a public program administrator charged with reducing emissions given realistic financial constraints and authority over emissions reductions and energy use. Opportunities are evaluated with respect to traditional public policy metrics, such as benefit-cost analysis, net benefit analysis, and cost-effectiveness. Section 2 summarizes current practices used to estimate greenhouse gas emissions from communities. I identify improved and alternative emissions inventory techniques such as disaggregating the sectors reported, reporting inventory uncertainty, and aligning inventories with local organizations that could facilitate emissions mitigation. The potential advantages and challenges of supplementing inventories with comparative benchmarks are also discussed. Finally, I highlight the need to integrate growth (population and economic) and business as usual implications (such as changes to electricity supply grids) into climate action planning. I demonstrate how these techniques could improve decision making when planning reductions, help communities set meaningful emission reduction targets, and facilitate CAP implementation and progress monitoring. Section 3 evaluates the costs and benefits of building energy efficiency are estimated as a means of reducing greenhouse gas emissions in Pittsburgh, PA and Austin, TX. Two policy objectives were evaluated: maximize GHG reductions given initial budget constraints or maximize social savings given target GHG reductions. This approach explicitly evaluates the trade-offs between three primary and often conflicting program design parameters: initial capital constraints, social savings

    Full Text Available Carbon monoxide (CO emissions influence global and regional air quality and global climate change by affecting atmospheric oxidants and secondary species. We simulate the influence of halving anthropogenic CO emissions globally and individually from 10 regions on surface and tropospheric ozone, methane, and aerosol concentrations using a global chemical transport model (MOZART-4 for the year 2005. Net radiative forcing (RF is then estimated using the GFDL (Geophysical Fluid Dynamics Laboratory standalone radiative transfer model. We estimate that halving global CO emissions decreases global annual average concentrations of surface ozone by 0.45 ppbv, tropospheric methane by 73 ppbv, and global annual net RF by 36.1 mW m−2, nearly equal to the sum of changes from the 10 regional reductions. Global annual net RF per unit change in emissions and the 100 yr global warming potential (GWP100 are estimated as −0.124 mW m−2 (Tg CO−1 and 1.34, respectively, for the global CO reduction, and ranging from −0.115 to −0.131 mW m−2 (Tg CO−1 and 1.26 to 1.44 across 10 regions, with the greatest sensitivities for regions in the tropics. The net RF distributions show widespread cooling corresponding to the O3 and CH4 decreases, and localized positive and negative net RFs due to changes in aerosols. The strongest annual net RF impacts occur within the tropics (28° S–28° N followed by the northern midlatitudes (28° N–60° N, independent of reduction region, while the greatest changes in surface CO and ozone concentrations occur within the reduction region. Some regional reductions strongly influence the air quality in other regions, such as East Asia, which has an impact on US surface ozone that is 93% of that from North America. Changes in the transport of CO and downwind ozone production clearly exceed the direct export of ozone from each reduction region. The small variation in CO GWPs among world regions suggests that future international

    To explore public awareness of carbon capture and storage (CCS), attitudes towards the use of CCS and the determinants of CCS acceptance in China, a study was conducted in July 2009 based on face-to-face interviews with participants across the country. The result showed that the awareness of CCS was low among the surveyed public in China, compared to other clean energy technologies. Respondents indicated a slightly supportive attitude towards the use of CCS as an alternative technology to CO{sub 2} emission reductions. The regression model revealed that in addition to CCS knowledge, respondents' understanding of the characteristics of CCS, such as the maturity of the technology, risks, capability of CO2 emission reductions, and CCS policy were all significant factors in predicting the acceptance of CCS. The findings suggest that integrating public education and communication into CCS development policy would be an effective strategy to overcome the barrier of low public acceptance. (author)

    Highlights: • Cooperative recycling achieves environmental, economic and social objectives. • We calculate GHG emissions reduction for a recycling cooperative in São Paulo, Brazil. • The cooperative merits consideration as a Clean Development Mechanism (CDM) project. • A CDM project would enhance the achievements of the recycling cooperative. • National and local waste management policies support the recycling cooperative. - Abstract: Solid waste, including municipal waste and its management, is a major challenge for most cities and among the key contributors to climate change. Greenhouse gas emissions can be reduced through recovery and recycling of resources from the municipal solid waste stream. In São Paulo, Brazil, recycling cooperatives play a crucial role in providing recycling services including collection, separation, cleaning, stocking, and sale of recyclable resources. The present research attempts to measure the greenhouse gas emission reductions achieved by the recycling cooperative Cooperpires, as well as highlight its socioeconomic benefits. Methods include participant observation, structured interviews, questionnaire application, and greenhouse gas accounting of recycling using a Clean Development Mechanism methodology. The results show that recycling cooperatives can achieve important energy savings and reductions in greenhouse gas emissions, and suggest there is an opportunity for Cooperpires and other similar recycling groups to participate in the carbon credit market. Based on these findings, the authors created a simple greenhouse gas accounting calculator for recyclers to estimate their emissions reductions

    1999-10-01

    The main research question of this study is as follows: What is the technical potential for reducing paper use in the field of publication applications in Western Europe within a time frame of 10-20 years, and what will the consequences for CO2 emissions be? To answer this central question we have defined the next four subquestions, all related to Western Europe: (1) How were the historical trends for the consumption figures of publication papers?; (2) What will be the expected publication paper consumption the next 10-20 years based on the historical trends, and what will be the influence on the related CO2 emissions?; (3) What technical opportunities do we see to reduce the future paper consumption trend for publication applications and what will be the individual and cumulative technical potential of these innovations?; (4) Does implementation of the technical opportunities lead to a significant dematerialization effect? Chapter 2 describes the chosen research method. In Chapter 3 we will introduce and define the paper types studied. Furthermore, Chapter 3 describes the detailed division of publication papers we have used in this study and the relationship with pulp and papermaking. After reading this chapter it has to be clear which paper production methods and paper types are (per ton) responsible for how much CO2 emissions. To get an overall-impression of the relevance of certain papers for CO2 emission numbers it is important to have insight into the historical consumption patterns of publication papers. Chapter 4 pays attention to these consumption patterns. Chapter 5 describes the most important trend factors that may influence future paper consumption patterns and in Chapter 6 this is translated into three possible consumption growth scenarios. The first and second growth scenarios are only based on extrapolations from historical figures, the third scenario is based on some of the most significant potential reduction measures. Furthermore, Chapter 6 gives

    Full Text Available Environmental Kuznets Curve (EKC hypothesis provides support for public policies that emphasize economic growth at the expense of environmental degradation. This hypothesis postulates an inverted U-shaped relationship between economic growth and environmental degradation with plausible explanations. We contribute to the discussion on EKC hypothesis by focusing on anthropogenic carbon dioxide (CO2 emission (a greenhouse gas during an extreme year. In the year 2005, concentration of anthropogenic CO2 became higher than the natural range observed over the last 650,000 years. Using econometric modeling of data from 122 countries for the year 2005, we study the key question: Does EKC hypothesis hold for anthropogenic CO2 emission after controlling for energy consumption and environmental governance? We do not find statistical support for EKC hypothesis. But, we find that improvements in environmental governance reduces CO2 emission. This suggests support for environmental policies that specifically promote CO2 emission reduction and does not emphasize economic growth at the expense of environmental degradation.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-5, Issue-2, March-May 2016, Page: 48-60

  10. Metropolitan density, energy efficiency and carbon emissions: Multi-attribute tradeoffs and their policy implications

    International Nuclear Information System (INIS)

    Clark, Thomas A.

    2013-01-01

    Of all the potential benefits of urban containment, compaction, and densification, just two are the central focus here: attainment of greater energy efficiency and reduction in carbon emissions. In cities these are largely associated with the transport and building sectors. This paper probes the form-efficiency relation in the transport sector across 57 census-defined urbanized areas in the United States in 2000. Thirty-six of the forty largest are included. Increase in core area population density is correlated with modest gain in energy efficiency in the urban transport sector and modest decrease in its carbon emissions. Densification's lagged effects related to travel rationalization and growth in transit receptivity may increase overall metro transport energy efficiency beyond the degree revealed here. These impacts are associated with two off-setting negative externalities: (1) diminished housing affordability, and (2) increased roadway congestion. Each may moderate over time. Such effects are non-additive, owing to a difference of metrics. Elevated CAFE standards provoking new transport technologies may reduce total energy consumption and associated emissions ceteris paribus, lessening densification's marginal efficiency payoff while magnifying the significance of densification's opportunity costs. Categories of policy interventions to promote metro-scale energy efficiencies and emissions reductions, with and without urban densification, conclude the paper. - Highlight: ► Transport VMT and Btu per capita are considered across 57 U.S. metro areas in 2000. ► Per capita VMT, Btu and vehicle emissions are inverse to metro core area population density. ► Interior road congestion and housing costs rise with core but not peripheral densification. ► Spatial non-density and aspatial transport approaches constitute alternate policy levers.

    The usefulness of scenarios for decision-makers is analyzed. First, a theoretical introduction to the scenario methodology is presented. Next, four energy scenarios for West-European passenger transport are developed. To start with, the present transport system as a baseline case is described and analysed. For each scenario it is outlined how the passenger transport system may look like in terms of the use of various existing and future transport technologies and the corresponding modal split. Expected energy consumption features of the various transport modes are described, data on the present fuel supply and electricity generation system are presented, as well as estimations of the future energy system. The energy consumption and CO2 emissions associated with the future passenger transport systems are assessed and these impacts are compared with the current system. The conclusion is that these scenarios provide interesting policy options for decision-makers. A large-scale reduction of CO2 emissions is possible in several ways, but each way will cause many problems, since drastic policy measures will have to be introduced, which may affect economic growth and the lifestyles of individuals. 5 figs., 11 tabs., 24 refs.

    2015-08-18

    This paper explores whether a Panama Canal Authority pollution tax could be an effective economic instrument to achieve Emission Control Area (ECA)-like reductions in emissions from ships transiting the Panama Canal. This tariff-based policy action, whereby vessels in compliance with International Maritime Organisation (IMO) ECA standards pay a lower transit tariff than noncompliant vessels, could be a feasible alternative to petitioning for a Panamanian ECA through the IMO. A $4.06/container fuel tax could incentivize ECA-compliant emissions reductions for nearly two-thirds of Panama Canal container vessels, mainly through fuel switching; if the vessel(s) also operate in IMO-defined ECAs, exhaust-gas treatment technologies may be cost-effective. The RATES model presented here compares current abatement technologies based on hours of operation within an ECA, computing costs for a container vessel to comply with ECA standards in addition to computing the Canal tax that would reduce emissions in Panama. Retrofitted open-loop scrubbers are cost-effective only for vessels operating within an ECA for more than 4500 h annually. Fuel switching is the least-cost option to industry for vessels that operate mostly outside of ECA regions, whereas vessels operating entirely within an ECA region could reduce compliance cost with exhaust-gas treatment technology (scrubbers).

  14. Effects of US biofuel policies on US and world petroleum product markets with consequences for greenhouse gas emissions

    International Nuclear Information System (INIS)

    Thompson, Wyatt; Whistance, Jarrett; Meyer, Seth

    2011-01-01

    US biofuel policy includes greenhouse gas reduction targets. Regulators do not address the potential that biofuel policy can have indirect impacts on greenhouse gases through its impacts on petroleum product markets, and scientific research only partially addresses this question. We use economic models of US biofuel and agricultural markets and US and world petroleum and petroleum product markets to show that discontinuing biofuel tax credits and ethanol tariff lower biofuel use could lead to increased US petroleum product use, and a reduction in petroleum product use in other parts of the world. The net effect is lower greenhouse gas emissions. Under certain assumptions, we show that biofuel use mandate elimination can have positive or negative impacts on greenhouse gas emissions. The magnitude and the direction of effects depend on how US biofuel trade affects biofuel in other countries with different emissions, context that determines how important use mandates are in the first place, who pays mandate costs, and the price responsiveness of global petroleum supplies and uses. However, our results show that counter-intuitive effects are possible and discourage broad conclusions about the greenhouse gas impacts of removing these elements of US biofuel policy. - Highlights: → Biofuel policy has counter-intuitive greenhouse gas effects under certain conditions. → US biofuel policies affect global petroleum markets, with implications for GHGs. → US biofuel use mandate GHG effects depend on whether they are binding and who pays. → US biofuel GHGs are sensitive to policy, petroleum market responses, and biofuel trade.

    the other side, instantaneous surface temperature is not the only parameter describing climate change. There are other parameters in the climate system that may depend more critically on the integration of the radiative forcing than its instantaneous value. This is probably the case of the deeper ocean thermal expansion, or large ice cap melting, two processes which are essential in producing irreversibility in the climate change. In this paper we wish to address another concern, which has not received much attention while we think it has large implications: the 'pulse' concept is clearly inadequate to describe current mitigation actions and the common practice of policy makers. In fact, almost all the emission mitigation programmes from international and national instances, whether already effective or considered for future action, correspond to emission reductions which should last at least several decades. Furthermore, the national programmes take as an implicit hypothesis that these reduction policies will perpetuate: at the end of a given action, a new reduction action is supposed to begin, at least equally effective, and hopefully more effective. So we have to consider that the mitigation measures we wish to evaluate will most generally perpetuate almost indefinitely. In addition, defining a methane (or CO 2 ) reduction programme involving new initiatives every year induces a continuous increase of this methane reduction. Opening a debate on a new definition of the GWP is troublesome for at least two reasons: (i) it may undermine international agreements that have been slow to construct; (ii) it may be seen in some cases as an incentive to substitute easier short-term strategies to the absolutely necessary reduction of CO 2 emissions, which carry the dominant and lasting impacts on climate. But CO 2 and CH 4 reductions are not in competition one against the other: they generally concern different economic actors and should be encouraged simultaneously

  16. Pulsating combustion - Combustion characteristics and reduction of emissions

    1999-11-01

    In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy. Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in recent years, due to its unique features. Various applications of pulsating combustion can be found, mainly as drying and heating devices, of which the latter also have had commercial success. It is, however, in the design process of a pulse combustor, difficult to predict the operating frequency, the heat release etc., due to the lack of a well founded theory of the phenomenon. Research concerning control over the combustion process is essential for developing high efficiency pulse combustors with low emissions. Natural gas fired Helmholtz type pulse combustors have been the experimental objects of this study. In order to investigate the interaction between the fluid dynamics and the chemistry in pulse combustors, laser based measuring techniques as well as other conventional measuring techniques have been used. The experimental results shows the possibilities to control the combustion characteristics of pulsating combustion. It is shown that the time scales in the large vortices created at the inlet to the combustion chamber are very important for the operation of the pulse combustor. By increasing/decreasing the time scale for the large scale mixing the timing of the heat release is changed and the operating characteristics of the pulse combustor changes. Three different means for NO{sub x} reduction in Helmholtz type pulse combustors have been investigated. These include exhaust gas recirculation, alteration of air/fuel ratio and changed inlet geometry in the combustion chamber. All used methods achieved less than 10 ppm NO{sub x} emitted (referred to stoichiometric

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) takes a look at the background, mechanisms and prognoses for the reduction of CO 2 emissions of new cars. This report focuses on policy measures - specifically the collection of budget-neutral so-called 'feebates' - that aim to influence the behaviour of buyers of new cars as a means of enhancing energy efficiency and reducing CO 2 emissions. Both the European Union and Switzerland are pursuing a three-pillar strategy in which agreements with manufacturers and importers (pillar 1) are supplemented by the provision of more detailed information for customers in the form of energy labels for new vehicles as well as catalogues listing levels of fuel consumption (pillar 2). Pillar 3 concerns measures aimed at influencing car buying behaviour, generally based on the use of the energy label for new vehicles in order to realise the existing potentials for reducing CO 2 emissions. The report takes a look at Switzerland's car market, buying behaviour, information on efficient vehicles, acceptance factors and incentive schemes. The findings of the study are presented and commented on.

    Even as the US debates an economy-wide CO 2 cap-and-trade policy the transportation sector remains a significant oil security and climate change concern. Transportation alone consumes the majority of the US's imported oil and produces a third of total US Greenhouse-Gas (GHG) emissions. This study examines different sector-specific policy scenarios for reducing GHG emissions and oil consumption in the US transportation sector under economy-wide CO 2 prices. The 2009 version of the Energy Information Administration's (EIA) National Energy Modeling System (NEMS), a general equilibrium model of US energy markets, enables quantitative estimates of the impact of economy-wide CO 2 prices and various transportation-specific policy options. We analyze fuel taxes, continued increases in fuel economy standards, and purchase tax credits for new vehicle purchases, as well as the impacts of combining these policies. All policy scenarios modeled fail to meet the Obama administration's goal of reducing GHG emissions 14% below 2005 levels by 2020. Purchase tax credits are expensive and ineffective at reducing emissions, while the largest reductions in GHG emissions result from increasing the cost of driving, thereby damping growth in vehicle miles traveled.

    In 2008, the government of Republic of Korea (Korea) announced the national abatement target aiming at 30% reductions from the Business-as-Usual projections by 2020. Accordingly, the Emission Trading Scheme (ETS) will be implemented from 2015 onwards. As ETS performance substantially depends on the structural design, it is critically important to examine the details of Korean ETS for the achievement of cost effectiveness and concurrent development of an active emission trading market. This paper addresses several policy design issues for this purpose. After providing an overview on the current framework of Korean ETS, we propose ways to achieve flexibility, consistency and market efficiency of the program in consideration of the preexisting policies. Issues in policy design are discussed by focusing on allowance allocation, market stabilization measures and price mechanism in the emission and energy markets in Korea. This paper will serve as a practical guideline for establishing sustainable and market-efficient Korean ETS that can be compatible with the international standards as in the EU ETS. - Highlights: • Emission Trading Scheme (ETS) will be implemented from 2015 in Korea to reduce CO 2 . • ETS performance substantially depends on structural design. • We provide policy overview on the current framework of Korean ETS. • Several policy design issues are discussed for developing policy consistency. • We focus on allowance allocation, allowance reserve and market stabilization measures

    This paper attempts to investigate the emissions embodied in Australia's economic growth and disaggregate primary energy sources used for electricity production. Using time series data over the period of 1990-2012, the ARDL bounds test approach to cointegration technique is applied to test the long-run association among the underlying variables. The regression results validate the long-run equilibrium relationship among all vectors and confirm that CO2 emissions, economic growth, and disaggregate primary energy consumption impact each other in the long-run path. Afterwards, the long- and short-run analyses are conducted using error correction model. The results show that economic growth, coal, oil, gas, and hydro energy sources have positive and statistically significant impact on CO2 emissions both in long and short run, with an exception of renewables which has negative impact only in the long run. The results conclude that Australia faces wide gap between emission abatement policies and targets. The country still relies on emission intensive fossil fuels (i.e., coal and oil) to meet the indigenous electricity demand.

    result in poor validation results, and this point particularly needs to be emphasized during policy development. For cases where sufficient calibration data are available, simulation models have demonstrated the ability to capture seasonal patterns of N2O flux. The reliability of statistical models likewise depends on data availability. Because soil moisture is a significant driver of N2O flux, the best outcomes occur when empirical models are applied to systems with relevant soil classification and climate. The structure of current carbon offset protocols is not well-aligned with a budgetary approach to GHG accounting. Current protocols credit field-scale reduction in N2O flux as a result of reduced fertilizer use. Protocols do not award farmers credit for reductions in CO2 emissions resulting from reduced production of synthetic N fertilizer. To achieve the greatest GHG emission reductions through reduced synthetic N production and reduced landscape N saturation requires a re-envisioning of the agricultural landscape to include cropping systems with legume and manure N sources. The current focus on on-farm GHG sources focuses credits on simple reductions of N applied in conventional systems rather than on developing cropping systems which promote higher recycling and retention of N.

    Nitrogen oxides (NOx) emission abatement of coal-fired power plants (CFPPs) requires large-scaled installation of selective catalytic reduction (SCR), which would reduce secondary fine particulate matter (PM2.5) (by reducing nitrate aerosol) in the atmosphere. However, our field measurement of two CFPPs equipped with SCR indicates a significant increase of SO42- and NH4+ emission in primary PM2.5, due to catalytic enhancement of SO2 oxidation to SO3 and introducing of NH3 as reducing agent. The subsequent formation of (NH4)2SO4 or NH4HSO4 aerosol is commonly concentrated in sub-micrometer particulate matter (PM1) with a bimodal pattern. The measurement at the inlet of stack also showed doubled primary PM2.5 emission by SCR operation. This effect should therefore be considered when updating emission inventory of CFPPs. By rough estimation, the enhanced primary PM2.5 emission from CFPPs by SCR operation would offset 12% of the ambient PM2.5 concentration reduction in cities as the benefit of national NOx emission abatement, which should draw attention of policy-makers for air pollution control.

    With advances in natural gas extraction technologies, there is an increase in the availability of domestic natural gas, and natural gas is gaining a larger share of use as a fuel in electricity production. At the power plant, natural gas is a cleaner burning fuel than coal, but uncertainties exist in the amount of methane leakage occurring upstream in the extraction and production of natural gas. At higher leakage levels, the additional methane emissions could offset the carbon dioxide emissions reduction benefit of switching from coal to natural gas. This analysis uses the MARKAL linear optimization model to compare the carbon emissions profiles and system-wide global warming potential of the U.S. energy system over a series of model runs in which the power sector is required to meet a specific carbon dioxide reduction target across a number of scenarios in which the availability of natural gas changes. Scenarios are run with carbon dioxide emissions and a range of upstream methane emission leakage rates from natural gas production along with upstream methane and carbon dioxide emissions associated with production of coal and oil. While the system carbon dioxide emissions are reduced in most scenarios, total carbon dioxide equivalent emissions show an increase in scenarios in which natural gas prices remain low and, simultaneously, methane emissions from natural gas production are higher. - Highlights: • MARKAL analysis of energy system GHG emissions reduction scenarios. • High methane leakage can eliminate the benefit that natural gas brings over coal. • A robust GHG reduction strategy takes into account upstream emissions for all fuels.

    The Yangtze River Delta (YRD) region is one of the most prosperous and densely populated regions in China and is facing tremendous pressure to mitigate vehicle emissions and improve air quality. Our assessment has revealed that mitigating vehicle emissions of NOx would be more difficult than reducing the emissions of other major vehicular pollutants (e.g., CO, HC and PM 2.5 ) in the YRD region. Even in Shanghai, where the emission control implemented are more stringent than in Jiangsu and Zhejiang, we observed little to no reduction in NOx emissions from 2000 to 2010. Emission-reduction targets for HC, NOx and PM 2.5 are determined using a response surface modeling tool for better air quality. We design city-specific emission control strategies for three vehicle-populated cities in the YRD region: Shanghai and Nanjing and Wuxi in Jiangsu. Our results indicate that even if stringent emission control consisting of the Euro 6/VI standards, the limitation of vehicle population and usage, and the scrappage of older vehicles is applied, Nanjing and Wuxi will not be able to meet the NOx emissions target by 2020. Therefore, additional control measures are proposed for Nanjing and Wuxi to further mitigate NOx emissions from heavy-duty diesel vehicles. Copyright © 2016. Published by Elsevier B.V.

  13. Asymmetric learning by doing and dynamically efficient policy: implications for domestic and international emissions permit trading of allocating permits usefully

    International Nuclear Information System (INIS)

    Read, Peter

    2000-01-01

    Learning by doing leads to cost reductions as suppliers move down the 'experience curve'. This results in a beneficial supply side inter-temporal externality that, for dynamic efficiency, requires a higher incentive for abatement innovations than the penalty on emissions. This effect can be achieved by a dedicated emissions tax or by a proportionate abatement obligation or by allocating permits usefully. The latter arrangement is compatible with the effective cap on emissions that is secured by an emissions trading scheme. Each of the three possibilities results in a reduced loss of international competitivity in policy-committed regions, in less 'leakage, and in more technology transfer. Implications for trading in emissions permits and in project-related credits are discussed. (Author)

    2015-04-01

    In September 2013, European institutions ratified the reform of the Common Agricultural Policy for 2014-2020 with new targets for combating climate change, making these an official goal for the Common Agricultural Policy (CAP). However the CAP's impact on greenhouse gas (GHG) emissions did not begin in 2014, even if it was previously ancillary to measures focusing on other targets. This Climate Report assesses emissions avoided and induced by the 2003-2013 CAP based on CAP measures modified in France over the period. A list of 20 major measures was drawn up. These met the following three criteria: The measure potentially has an impact on GHG emissions; The annual budget allocated to the measure is more than euro 20 million a year; The measure was created or modified between 2003 and 2013 Their positive or negative impact on GHG emissions was then estimated at a unitary level (per hectare, animal, square metre of greenhouse, etc.), on a national scale (MtCO 2 e per year) and relative to the quantity produced (tCO 2 e per litre of milk, quintal of wheat, etc.). Almost all these measures encourage emissions reduction, whatever the metric considered: tCO 2 e per hectare or per quantity of product. In just under half of cases, however, the incentive is not considered to be effective, with the data (e.g. surface area of grasslands, quantity of animals, etc.) moving in the opposite direction from the expected effects of the measure. The effects from the other half of measures is estimated at more than 2 million tCO 2 e per year, or around 2% of emissions from the agri-supply, agriculture and agri-food (AAA) sectors in 2011. Two-thirds of these reductions can be attributed to three types of measures: incentives for sustainable use of inputs (green environment plan, energy performance plan, training, etc.), agri-environmental grassland premium and coupled support for grain legumes. The main purpose of these calculations is to spark a debate. The assumptions underlying

    The modeling of the reference scenario and the various reduction scenarios in PAREST was based on the Central System of Emissions (CSE) (CSE, 2007). Emissions from road traffic were calculated by using the traffic emission model TREMOD (Knoerr et al., 2005) and fed into the CSE. The version TREMOD 4.17 has been used. The resulting emission levels in PAREST reference scenario were supplemented by the emission-reducing effect of the implementation of the future Euro 5 and 6 emission standards for cars and light commercial vehicles and Euro VI for heavy commercial vehicles in combination with the truck toll extension.

    This report assesses the impact of the unilateral greenhouse gas emission reductions proposed by the EU on the structure of European and Finnish energy systems with TIMES models. The two models used are techno-economical energy system models including an extensive description of technologies on energy production and consumption. The models derive the sectoral energy demand from given economic projections and calculate the optimal way of satisfying the energy demand through market equilibrium. The basis for EU wide calculations was the Common POLES-IMAGE economic scenarios which project a GDP growth of 2.4 % p.a. until 2020. A sensitivity analysis was conducted with a lower economic growth projection. The results indicated that a reduction of 20 % compared to 1990 emission levels by 2020 would lead to most reductions being conducted at the electricity sector. The consumption of coal in electricity generation would decrease considerably. In the long term some of the natural gas based production would incorporate carbon capture and storage (CCS), and the use of wind power would grow substantially. The value of carbon would lie at levels around 20 to 30 euro/t CO 2 by 2020 were the reductions carried out without flexibility mechanisms. With a reduction target of -30 % by 2050, the value of carbon would rise to 40 . 50 euro/t CO 2 by 2050, and nearly to 100 euro/t CO 2 with a target of -60 % in 2050. The calculations on Finland were based on economic projections by the Ministry of Finance and the Government Institute of Economic Research. The scenarios asses the optimal way of reducing Finnish emissions with a range of prices for emission rights between 20 and 50 euro/t CO 2 . The sectors not included in the emission trading scheme were assumed to conduct reductions with costs up to the value of emission rights. The use of coal was reduced after 2010, accompanied by an increase in the use of natural gas. The utilization of bioenergy increases considerable in the total

    Emissions trading is considered to be a cost-effective environmental economic instrument for pollution control. However, the pilot emissions trading programs in China have failed to bring remarkable success in the campaign for pollution control. The policy design of an emissions trading program is found to have a decisive impact on its performance. In this study, an artificial market for sulfur dioxide (SO2) emissions trading applying the agent-based model was constructed. The performance of the Jiangsu SO2 emissions trading market under different policy design scenario was also examined. Results show that the market efficiency of emissions trading is significantly affected by policy design and existing policies. China's coal-electricity price system is the principal factor influencing the performance of the SO2 emissions trading market. Transaction costs would also reduce market efficiency. In addition, current-level emissions discharge fee/tax and banking mechanisms do not distinctly affect policy performance. Thus, applying emissions trading in emission control in China should consider policy design and interaction with other existing policies.

    The role of emissions of volatile organic compounds and nitric oxide from biogenic sources is becoming increasingly important in regulatory air quality modeling as levels of anthropogenic emissions continue to decrease and stricter health-based air quality standards are being adopted. However, considerable uncertainties still exist in the current estimation methodologies for biogenic emissions. The impact of these uncertainties on ozone and fine particulate matter (PM2.5) levels for the eastern United States was studied, focusing on biogenic emissions estimates from two commonly used biogenic emission models, the Model of Emissions of Gases and Aerosols from Nature (MEGAN) and the Biogenic Emissions Inventory System (BEIS). Photochemical grid modeling simulations were performed for two scenarios: one reflecting present day conditions and the other reflecting a hypothetical future year with reductions in emissions of anthropogenic oxides of nitrogen (NOx). For ozone, the use of MEGAN emissions resulted in a higher ozone response to hypothetical anthropogenic NOx emission reductions compared with BEIS. Applying the current U.S. Environmental Protection Agency guidance on regulatory air quality modeling in conjunction with typical maximum ozone concentrations, the differences in estimated future year ozone design values (DVF) stemming from differences in biogenic emissions estimates were on the order of 4 parts per billion (ppb), corresponding to approximately 5% of the daily maximum 8-hr ozone National Ambient Air Quality Standard (NAAQS) of 75 ppb. For PM2.5, the differences were 0.1-0.25 microg/m3 in the summer total organic mass component of DVFs, corresponding to approximately 1-2% of the value of the annual PM2.5 NAAQS of 15 microg/m3. Spatial variations in the ozone and PM2.5 differences also reveal that the impacts of different biogenic emission estimates on ozone and PM2.5 levels are dependent on ambient levels of anthropogenic emissions.

  2. Livestock-related greenhouse gas emissions: impacts and options for policy makers

    International Nuclear Information System (INIS)

    Garnett, Tara

    2009-01-01

    Research shows that livestock account for a significant proportion of greenhouse gas (GHG) emissions and global consumption of livestock products is growing rapidly. This paper reviews the life cycle analysis (LCA) approach to quantifying these emissions and argues that, given the dynamic complexity of our food system, it offers a limited understanding of livestock's GHG impacts. It is argued that LCA's conclusions need rather to be considered within a broader conceptual framework that incorporates three key additional perspectives. The first is an understanding of the indirect second order effects of livestock production on land use change and associated CO 2 emissions. The second compares the opportunity cost of using land and resources to rear animals with their use for other food or non-food purposes. The third perspective is need-the paper considers how far people need livestock products at all. These perspectives are used as lenses through which to explore both the impacts of livestock production and the mitigation approaches that are being proposed. The discussion is then broadened to consider whether it is possible to substantially reduce livestock emissions through technological measures alone, or whether reductions in livestock consumption will additionally be required. The paper argues for policy strategies that explicitly combine GHG mitigation with measures to improve food security and concludes with suggestions for further research.

    Africa's response to climate change has largely been focused on adaptation rather than mitigation. The reason for this is based on the fact that the continent contributes very little to global CO2 emission. Again, mitigation policies like carbon tax as being practised in developed countries may be costly and difficult to implement in a continent where most economies are fragile. Using behavioural change as an adaptation approach, we examined the opinion of Ibadan city residents towards energy conservation and CO2 emissions reduction. A total of 822 respondents were sampled across the three residential neighbourhoods of the city. Results from the study showed that female and male respondents differed in their opinion towards energy conservation. However, the female respondents tended to record higher mean scores on majority of the items used to capture energy conservation behaviour than their male counterparts. Also, those with higher level of education seemed to be more conscious of the environmental consequences arising from energy use at home than those with lower educational background. However, very slight variations were recorded in the mean value score across the different age groups, those respondents above 50 years scored a bit higher than other age groups.

  6. The impacts of electricity dispatch protocols on the emission reductions due to wind power and carbon tax.

    2015-02-17

    Two dispatch protocols have been adopted by electricity markets to deal with the uncertainty of wind power but the effects of the selection between the dispatch protocols have not been comprehensively analyzed. We establish a framework to compare the impacts of adopting different dispatch protocols on the efficacy of using wind power and implementing a carbon tax to reduce emissions. We suggest that a market has high potential to achieve greater emission reduction by adopting the stochastic dispatch protocol instead of the static protocol when the wind energy in the market is highly uncertain or the market has enough adjustable generators, such as gas-fired combustion generators. Furthermore, the carbon-tax policy is more cost-efficient for reducing CO2 emission when the market operates according to the stochastic protocol rather than the static protocol. An empirical study, which is calibrated according to the data from the Electric Reliability Council of Texas market, confirms that using wind energy in the Texas market results in a 12% CO2 emission reduction when the market uses the stochastic dispatch protocol instead of the 8% emission reduction associated with the static protocol. In addition, if a 6$/ton carbon tax is implemented in the Texas market operated according to the stochastic protocol, the CO2 emission is similar to the emission level from the same market with a 16$/ton carbon tax operated according to the static protocol. Correspondingly, the 16$/ton carbon tax associated with the static protocol costs 42.6% more than the 6$/ton carbon tax associated with the stochastic protocol.

    A 20% reduction of greenhouse gas (GHG) emissions by 2020 is one of the main objectives of the European Union (EU) energy policy. However, this overall objective does not specify how it should be distributed among the Member States, according to each one's particular characteristics. Consequently, in this article a non-linear distribution methodology with dynamic objective targets for reducing GHG emissions is proposed. The goal of this methodology is to promote debate over the weighting of these overall objectives, according to the context and characteristics of each member state. First, an analysis is conducted of the situation of greenhouse gas emissions in the reference year (1990) used by the EU for reaching its goal of reducing them by 20% by 2020, and its progress from 1990 to 2007. Then, the methodology proposed was applied for the year 2020 on two territorial aggregation levels following the EUROSTAT Nomenclature of Territorial Units for Statistics (NUTS), in the EU-15 and EU-27 member countries and on a regional level in 19 Spanish Autonomous Communities and Cities (NUTS-2). Weighting is done based on CO 2 intensity, GHG emissions per capita and GHG emissions per GDP. Finally, several recommendations are provided for the formulation of energy policies.

    Road transport is an important part of transportation, and road in the field of energy-saving emission reduction is a very important industry. According to the existing problems of road energy saving and emission reduction, this paper elaborates the domestic and international research on energy saving and emission reduction from three aspects: road network optimization, pavement material and pavement maintenance. Road network optimization may be overlooked, and the research content is still relatively preliminary; pavement materials mainly from the asphalt pavement temperature mixed asphalt technology research; pavement maintenance technology development is relatively comprehensive.

    Full Text Available With methyl bromide's phase-out, most growers have turned to alternative fumigants, particularly 1,3-dichloropropene (1,3-D and chloropicrin. These alternatives are tightly regulated because they are classified as toxic air contaminants and volatile organic compounds; the latter combine with other substances to produce ground-level ozone (smog. Two ambient air monitoring studies were conducted to evaluate the potential of totally impermeable film (TIF to reduce emissions from shank applications of chloropicrin and 1,3-D. In 2009, a study demonstrated that TIF reduced chloropicrin and 1,3-D peak emissions by 45% and 38%, respectively, but TIF did not reduce total emissions when it was cut after 6 days. In 2011, increasing the tarp period from 5 to 10 days decreased chloropicrin and 1,3-D peak emissions by 88% and 78%, and their total emissions by 64% and 43%, respectively. Concurrent dynamic flux chamber results corroborated the ambient air monitoring data. These studies provide regulatory agencies with mitigation measures that should allow continued fumigant use at efficacious application rates.

    EPA Region 4 concluded in a recent comparative environmental risk evaluation that global climate change could substantially impact the Southeast. To address this risk, Region 4 developed an action plan to promote cost-effective pollution prevention and reduce greenhouse gas emissions, The regional plan contains programs that aye specific to Region 4 as well as geographic components of the national Climate Change Action Plan. Sources of carbon dioxide emissions were targeted for pollution prevention based on an energy model that allows the user to create energy efficiency scenarios in four sectors: residential, commercial, industrial, and transportation. Activities were selected using the modeled information on sector reduction potentials and resource and cost-effectiveness criteria. Given the high level of uncertainty associated with climate change projections, the programs developed are all cost effective, prevent pollution and/or result in sound adaptation policies. Currently, policy makers at national, regional, and local levels are deciding on what types of energy efficiency programs to implement. The region's action plan is composed of several programs and approaches. The authors have developed implemented, and/or participated in the following: energy scenario model. EARTHWALK (residential energy conservation); energy conservation in affordable homes (new residences); Cool Communities Program (strategic tree planting and light colored surfaces); EPA's Green Lights Program; WAVE (water conservation), the Plant Protection Center; QUEST TO SAVE THE EARTH (outreach tools); energy and water use planning for the 1996 Olympic Games, and planning for sea-level rise. Reviewing the practices of the above programs will be the focus of this paper

    Many countries committed themselves in the Kyoto protocol to reduce greenhouse gas (GHG) emissions. Some of these targeted emission reductions could result from a switch from coal-fired to gas-fired electricity generation. The focus in this work lies on Western Europe, with the presence of the European Union Emission Trading Scheme (EU ETS). For the switching to occur, several conditions have to be fulfilled. First, an economical incentive must be present, i.e. a sufficiently high European Union Allowance (EUA) price together with a sufficiently low natural gas price. Second, the physical potential for switching must exist, i.e. at a given load, there must remain enough power plants not running to make switching possible. This paper investigates what possibilities exist for switching coal-fired plants for gas-fired plants, dependent on the load level (the latter condition above). A fixed allowance cost and a variable natural gas price are assumed. The method to address GHG emission reduction potentials is first illustrated in a methodological case. Next, the GHG emission reduction potentials are addressed for several Western European countries together with a relative positioning of their electricity generation. GHG emission reduction potentials are also compared with simulation results. GHG emission reduction potentials tend to be significant. The Netherlands have a very widespread switching zone, so GHG emission reduction is practically independent of electricity generation. Other counties, like Germany, Spain and Italy could reduce GHG emissions significantly by switching. With an allowance cost following the switch level of a 50% efficient gas-fired plant and a 40% efficient coal-fired plant in the summer season (like in 2005), the global GHG emission reduction (in the electricity generating sector) for the eight modeled zones could amount to 19%

In parallel, 5% and 6.4% of colorectal cancer and CVD deaths would be avoided if the Italian population ate the advised quantity of processed meat. Life table analysis suggests that the scenario that is fully compliant with the Mediterranean diet model would save 5 million years of life lost prematurely among men and women over the next 18 years and would increase average life expectancy of future generations by over 7 months. Considering the environmental impact, emissions associated with the actual total intake of beef range from 12,900 to 21,800 Gg CO2 eq; emissions saved according to the Mediterranean scenario are in the range 8000-14000 Gg CO2 eq per year. The per capita reduction is 263 KgCO2eq/year/person with higher reductions in Northwestern and Central areas.In Italy, scenarios for reducing beef consumption are consistent with significant health and environmental co-benefits on current and future generations. Results support introducing policies to promote healthier behavior towards red and processed meat in the adult population within an overall balanced and healthy dietary pattern. Interventions should address gender, vulnerable population groups, and geographical differences in order to be more effective.

    This paper studies the operation of an electric grid with renewable wind generation and plug-in electric vehicles (PEVs). In particular, PEVs will be the controllable demand that can mitigate the intermittency in wind generation and improve the capacity factors of the non-renewable generation assets on the grid. Optimization problems are formulated to minimize the costs of electricity generation, and two approaches are proposed to address the grid CO 2 emission in the optimization. The first approach directly penalizes CO 2 in the objective function, and the second approach adopts a carbon disincentive policy to alter the dispatch order of power plants, so that expensive low-CO 2 plants can replace cheap high-CO 2 plants. These two approaches result in very different outcomes: the first approach affects only the PEV charging demand on the grid and does not result in significant CO 2 reduction, whereas the second approach controls both the generation and load, and CO 2 can be reduced substantially. In addition, the carbon disincentive policy, unlike a carbon tax, does not collect any revenue; therefore, the increase in electricity cost is minimal. The effect of the proposed algorithms on the grid electricity cost and carbon emission is analyzed in details and reported. - Highlights: • We study the tradeoff between CO 2 emissions and generation cost on an electric grid. • The tradeoff was shown by Pareto fronts obtained from optimizations. • Pareto fronts shows that a carbon disincentive is effective in reducing emissions. • Controlling both supply and demand on the grid is necessary to reduce CO 2 and costs

    A new exhaust emission inventory of ocean-going vessels (OGVs) was compiled for Hong Kong by using Automatic Identification System (AIS) data for the first time to determine typical main engine load factors, through vessel speed and operation mode characterization. It was found that in 2007, container vessel was the top emitting vessel type, contributing 9,886, 11,480, 1,173, 521 and 1166 tonnes of SO2, NOx, PM10, VOC and CO, respectively, or about 80%-82% of the emissions. The top five, which also included ocean cruise, oil tanker, conventional cargo vessel and dry bulk carrier, accounted for about 98% of emissions. Emission maps, which add a new spatial dimension to the inventory, show the key emission hot spots in Hong Kong and suggest that a significant portion of emissions were emitted at berth. Scientific evidence about the scale and distribution of ship emissions has contributed in raising public awareness and facilitating stakeholder engagement about the issue. Fair Winds Charter, the world's first industry-led voluntary emissions reduction initiative, is a perfect example of how careful scientific research can be used in public engagement and policy deliberation to help drive voluntary industry actions and then government proposals to control and regulate marine emissions in Hong Kong and the Pearl River Delta region.

    This study takes environmental policy stringency and economic activity as the controlling variables and forecasts the CO 2 emissions in China up to 2022. In doing so, an application of corrected grey model with convolution is used over the annual time series data between 1990 and 2012. The simulation results show that (1) between 2012 and 2022, CO 2 emissions in China is expected to increase at an average rate of 17.46% annually, raising the emissions intensity from 7.04 in 2012 to 25.461 metric tons per capita by 2022; (2) stringent environmental policies reduce CO 2 emissions-whereas, GDP tends to increase the emissions intensity in China; (3) stringent environmental policies are found to have a negative impact on GDP in China. Based on the empirical findings, the study also provides some policy suggestions to reduce emissions intensity in China.

    CO 2 emissions from maritime transport represent a significant part of total global greenhouse gas (GHG) emissions. According to the International Maritime Organization (), maritime transport emitted 1046 million tons (all tons are metric) of CO 2 in 2007, representing 3.3% of the world's total CO 2 emissions. The International Maritime Organization (IMO) is currently debating both technical and market-based measures for reducing greenhouse gas emissions from shipping. This paper presents investigations on the effects of speed reductions on the direct emissions and costs of maritime transport, for which the selection of ship classes was made to facilitate an aggregated representation of the world fleet. The results show that there is a substantial potential for reducing CO 2 emissions in shipping. Emissions can be reduced by 19% with a negative abatement cost (cost minimization) and by 28% at a zero abatement cost. Since these emission reductions are based purely on lower speeds, they can in part be performed now. - Highlights: → We investigates the effects of speed reductions for maritime transport. → The selection of ship classes represent the words fleet. → The transport volumes are kept constant. → The model includes both cost and emissions as a function of speed. → The results show that there is a substantial potential for reducing CO 2 emissions from shipping.

    On road transport emissions is kicking off in Indian cities due to high levels of urbanization and economic growth during the last decade in Indian subcontinent. In 1951, about 17% of India's population were living in urban areas that increased to 32% in 2011. Currently, India is fourth largest Green House Gas (GHG) emitter in the world, with its transport sector being the second largest contributor of CO2 emissions. For achieving prospective carbon reduction targets, substantial opportunity among in-use vehicle is necessary to quantify. Since, urban traffic flow and operating condition has significant impact on exhaust emission (Choudhary and Gokhale, 2016). This study examined the influence of vehicular operating kinetics on CO2 emission from predominant private transportation vehicles of Indian metropolitan city, Guwahati. On-board instantaneous data were used to quantify the impact of CO2 emission on different mileage passenger cars and auto-rickshaws at different times of the day. Further study investigates CO2 emission reduction strategies by using International Vehicle Emission (IVE) model to improve co-benefit in private transportation by integrated effort such as gradual phase-out of inefficient vehicle and low carbon fuel. The analysis suggests that fuel type, vehicles maintenance and traffic flow management have potential for reduction of urban sector GHG emissions.

    One of the great challenges for policy makers in the twenty first century is turning out to be global climate change caused by greenhouse gas emissions. Recent setbacks in international negotiations do not preclude the imposition of national emission targets. One option being studied to increase the economic efficiency of meeting these targets is the creation of emissions trading markets. The exploration of credit trading in the field of greenhouse gas emissions is carried out under the banner of the Greenhouse Gas Emission Reduction Trading (GERT) Pilot Project. One of its objectives is the development of the institutional framework required for the Clean Development Mechanism (CDM), Joint Implementation (JI), and other international credit trading programs. To ensure credits are awarded to projects in a fair and transparent manner, technical, methodological, and administrative processes must be put in place. The determination of project baselines and project boundaries represent two of the main challenges confronting policy makers in awarding the credits. A review of baseline and boundary methods was initiated by GERT, and this report also contains a description of the main advantages and drawbacks of the various methods being considered. Lessons learned and opportunities are especially important for GERT to provide proper guidance to developers. The context and rationale for baselines and boundary setting are first explored in this report, as well as the issues of importance, and common criteria for the evaluation of alternative methods. The principal options for baseline determination, advantages and disadvantages, and applicability in various contexts were reviewed in section 2. The topic of avoided electricity use, and how to set consistent baselines for it are discussed in section 3. Project boundary is the topic of section 4, including leakage, upstream and downstream emissions, rebound and positive spillover effects, and means by which these issues can de

    The objective of a greenhouse gas (GHG) emissions trading scheme (ETS) is to reduce emissions by transitioning the economy away from the production and consumption of goods and services that are GHG intensive. A GHG ETS has been a public policy issue in Australia for over a decade. The latest policy initiative on an ETS is the proposed Carbon Pollution Reduction Scheme (CPRS). A substantial share of Australia's total GHG reduction under the CPRS is expected to come from the electricity generation sector. This paper surveys the literature on investment behaviour under an ETS. It specifically focuses on the relationship between the design of an ETS and a generator's decisions to invest in low emissions plant and retire high emissions plant. The proposed CPRS provides the context for presenting key findings along with the implications for the electricity generation sector's transition to lower emissions plant. The literature shows that design features such as the method of allocating permits, the stringency of the emissions cap along with permit price uncertainty, provisions for banking, borrowing and internationally trading permits, and the credibility of emissions caps and policy uncertainty may all significantly impact on the investment and retirement behaviour of generators.

    It is one of the common targets and important tasks for energy management and environmental control of Beijing to improve urban air quality while reducing the emissions of greenhouse gases (GHG). Here, based on the interim and long term developmental planning and energy structure of the city, three energy consumption scenarios in low, moderate and high restrictions were designed by taking the potential energy saving policies and environmental targets into account. The long-range energy alternatives planning (LEAP) model was employed to predict and evaluate reduction effects of the chief air pollutants and GHG during 2010 to 2020 under the three given scenarios. The results showed that if urban energy consumption system was optimized or adjusted by exercising energy saving and emission reduction and pollution control measures, the predicted energy uses will be reduced by 10 to 30 million tons of coal equivalents by 2020. Under the two energy scenarios with moderate and high restrictions, the anticipated emissions of SO2, NOx, PM10, PM2.5, VOC and GHG will be respectively reduced to 71 to 100.2, 159.2 to 218.7, 89.8 to 133.8, 51.4 to 96.0, 56.4 to 74.8 and 148 200 to 164 700 thousand tons. Correspondingly, when compared with the low-restriction scenario, the reducing rate will be 53% to 67% , 50% to 64% , 33% to 55% , 25% to 60% , 41% to 55% and 26% to 34% respectively. Furthermore, based on a study of synergistic emission reduction of the air pollutants and GHG, it was proposed that the adjustment and control of energy consumptions shall be intensively developed in the three sectors of industry, transportation and services. In this way the synergistic reduction of the emissions of chief air pollutants and GHG will be achieved; meanwhile the pressures of energy demands may be deliberately relieved.

    The Ministry of Science and Technology of China organized experts to develop the Internet-based software Counter of Energy Conservation and Emission Reduction to directly measure energy conservation and emission reduction potentials in people's daily lives. Research and testing of the software have been completed, and the software is available to the public on the Internet. The Counter of Energy Conservation and Emission Reduction software is being promoted with the aim of stimulating the public's enthusiasm for energy conservation and emission reduction. The software is of great significance in energy conservation and emission reduction education oriented to elementary and middle school students and community residents, thus changing the lagged public participation of Chinese citizens in energy conservation and emission reduction. The counter can calculate people's energy conservation and emission reduction potential in six aspects of daily life. The user can know his or her value of energy conservation and emission reduction in each aspect by clicking the options in keeping with his or her true daily routines. The user can also know the amounts of energy conservation and emission reduction as well as the potential energy conservation and emission reduction of the whole nation by clicking the Effect Calculation Button. Family life areas mainly include the methods and habits of water use, the use of energy conservation cookers, methods of saving paper, the use of environmental protection products, the habit of home appliance use, and the methods of washing clothing, especially the use of the washing machine with the function of energy conservation. Housing includes the building materials, the heating and cooling systems, the temperature control measures, and the lighting, etc. Heating and cooling times for the house by air conditioner should be reduced. Architects can do a great deal by using energy-efficient building materials and designing houses

    We compare different options for the use of lignocellulosic biomass to reduce CO{sub 2} emission and oil use, focusing on polygeneration of biomass-based motor fuels and electricity, and discuss methodological issues related to such comparisons. The use of biomass can significantly reduce CO{sub 2} emission and oil use, but there is a trade-off between the reductions in CO{sub 2} emission and oil use. Bioelectricity from stand-alone plants replacing coal-based electricity reduced CO{sub 2} emission by 99 kg per GJ biomass input but gave no oil use reduction. Stand-alone produced methanol replacing diesel reduced the CO{sub 2} emission with 38 kg and the oil use with 0.67 GJ per GJ biomass, indicating that a potential CO{sub 2} emission reduction of 90 kg is lost per GJ oil reduced. CO{sub 2} emission and oil use reduction for alternatives co-producing fuel and electricity fall between the stand-alone alternatives. Plug-in hybrid-electric vehicles using bioelectricity reduced CO{sub 2} emission by 75-88 kg and oil use by 0.99-1.2 GJ, per GJ biomass input. Biomass can also reduce CO{sub 2} emission and/or oil use more efficiently if fossil-fuel-fired boilers or electric heating is replaced by district heating from biomass-based combined heat and power generation. This is also true if electricity or motor fuel is produced from black liquor gasification in pulp mills or if wood is used instead of concrete in building construction. Biomass gasification is an important technology to achieve large reductions, irrespective of whether CO{sub 2} emission or oil use reduction is prioritised. (author)

    2015-01-01

    The European Union has identified the typical areas of application of measures to tackle the problem of pollutants emissions into the air. Road transport is recognized as the largest polluter of the environment and an increase in CO2 emissions is most difficult to suppress in this type of transport. Looking at the projected trend of emission reductions in Croatia, it is clear that for achieving the minimum targets by 2050, as proposed by the European Union, implementation of the very strong measures in the coming period will be inevitable. The main aim of the paper refers to the analysis of potential emission reduction of pollutants generated by passenger vehicles registered in Croatia, assuming the implementation of measures that will result in technological renewal of the fleet at the national level. Generally considering, passenger cars before the Euro 1 standard, Euro 1 and Euro 2 standards together emit nearly 40 percent of all CO2 emissions generated by passenger cars registered in Croatia. Assuming replacement of all cars up to and including Euro 2, with Euro 6 vehicles, and taking into account certain assumptions, the potential reductions in emissions of NOx, CO, CH4 and particles were quantified. The potential reduction in NOx emissions is approximately 3,061 tons, in CO emissions approximately 14482 tons, in CH4 approximately 114 tons and in particulate matter approximately 257 tons. Depending on the engine size, with the replacement of the typical gasoline 20 years old passenger vehicle with the new one, without changing the driving mode, annual savings of up to 209 liters of gasoline fuel and reduction of CO2 emissions by 475 kg could be achieved (according to the assumptions described in the paper). With the replacement of diesel vehicles under the same conditions, the savings of up to 311 liters of diesel fuel annually and reduction of CO2 emissions by 815 kg could be achieved. (author).

    To reduce greenhouse gas emissions from deforestation, Indonesia instituted a nationwide moratorium on new license areas (“concessions”) for oil palm plantations, timber plantations, and logging activity on primary forests and peat lands after May 2011. Here we indirectly evaluate the effectiveness of this policy using annual nationwide data on deforestation, concession licenses, and potential agricultural revenue from the decade preceding the moratorium. We estimate that on average granting a concession for oil palm, timber, or logging in Indonesia increased site-level deforestation rates by 17–127%, 44–129%, or 3.1–11.1%, respectively, above what would have occurred otherwise. We further estimate that if Indonesia’s moratorium had been in place from 2000 to 2010, then nationwide emissions from deforestation over that decade would have been 241–615 MtCO2e (2.8–7.2%) lower without leakage, or 213–545 MtCO2e (2.5–6.4%) lower with leakage. As a benchmark, an equivalent reduction in emissions could have been achieved using a carbon price-based instrument at a carbon price of $3.30–7.50/tCO2e (mandatory) or $12.95–19.45/tCO2e (voluntary). For Indonesia to have achieved its target of reducing emissions by 26%, the geographic scope of the moratorium would have had to expand beyond new concessions (15.0% of emissions from deforestation and peat degradation) to also include existing concessions (21.1% of emissions) and address deforestation outside of concessions and protected areas (58.7% of emissions). Place-based policies, such as moratoria, may be best thought of as bridge strategies that can be implemented rapidly while the institutions necessary to enable carbon price-based instruments are developed.

  12. The effects of fiscal policy on CO_2 emissions: Evidence from the U.S.A

    2016-01-01

    This paper examines the effects of fiscal policy on CO_2 emissions using Vector Autoregressions on U.S. quarterly data from 1973 to 2013. In particular, we analyze the short- and mid-term interactions between fiscal policy and emissions by using sign restrictions to identify the policy shocks. We construct the impulse responses to linear combinations of fiscal shocks, corresponding to the scenarios of deficit-financed spending and deficit-financed tax-cuts. To consider possible variations of the effect of fiscal policy according to the sources of pollution, we distinguish between production- and consumption- generated CO_2 emissions. The results point out that the implementation of expansionary fiscal spending provides an alleviating effect on emissions from both sources of the pollutant, whereas deficit-financed tax-cuts are associated with an increase on consumption-generated CO_2 emissions. The exact pattern of the effects depends on the source of emissions, the scenario of fiscal policy that is implemented and the functional class of government expenditure being increased. - Highlights: • We investigate the effects of fiscal policy on CO_2 emissions using VAR methods. • Spending expansions reduce production- and consumption- generated CO_2 emissions. • This alleviating effect is greater when increasing certain expenditure categories. • Deficit-financed tax-cuts increase consumption-generated CO_2 emissions. • Unique factors in U.S. may limit applicability of findings to other jurisdictions.

  13. Potential for reduction of methane emissions from dairy cows

    Methane is a gas cows naturally produce in the rumen. However, it is also a potential greenhouse gas. Therefore, there is a certain interest from an environmental point of view to reduce methane emissions from dairy cows.

    Coal production globally is projected to grow in the foreseeable future. Countries with heavy reliance on coal could reduce methane and other emissions through the capture and utilization of coal mine methane (CMM) in the short and medium term, while they pursue structural and long-term economic changes. Several countries have successfully implemented policies to promote CMM capture and utilization; however, some countries still struggle to implement projects. This paper outlines key factors to consider in adapting policies for CMM mitigation. The authors propose an approach for selecting adequate mechanisms for stimulating CMM mitigation that involves reviewing global best practices and categorizing them functionally either as mechanisms needed to improve the underlying conditions or as CMM-specific policies. It is important to understand local policy frameworks and to consider whether it is more feasible to improve underlying policy conditions or to provide targeted incentives as an interim measure. Using Kazakhstan as a case study, the authors demonstrate how policymakers could assess the overall policy framework to find the most promising options to facilitate CMM projects. Kazakhstan’s emissions from underground coal mines have been increasing both in total and per tonne of coal production, while overall production has been declining. CMM mitigation presents an opportunity for the country to reduce its greenhouse gas emissions in the near and medium term, while the government pursues sustainable development goals. Analysis shows that policymakers in Kazakhstan can leverage existing policies to stimulate utilization by extending feed-in tariffs to cover CMM and by developing working methodologies for companies to obtain emission reduction credits from CMM projects.

  19. A basis for greenhouse gas trading in agriculture : Final report of the emission reduction trading protocol team

    International Nuclear Information System (INIS)

    2002-01-01

    A link has been established between increasing levels of greenhouse gases in the atmosphere and the rise in global temperatures. The burning of fossil fuels, land use changes, agricultural and industrial activities play a large part in the increase of greenhouse gases and result in in changes to temperature, precipitation and weather patterns. The two methods that can be used to reduce the buildup of greenhouse gases in the atmosphere are the reduction of the gases and the sequestration of carbon dioxide (carbon dioxide is absorbed) into terrestrial processes. Several policy options are being considered to effect this reduction in buildup, and one of those includes the implementation of a tradable system of emission permits. Such a scenario would involve the agricultural sector removing and reducing on-farm emissions of greenhouse gases, thereby earning it credits that could then be sold to those industries that face tougher greenhouse gases control costs. The study led to several findings: (1) trades in carbon dioxide in the Albertan agricultural sector and changes in agricultural practices could lead to reductions of up to 5 million tonnes per year to 2008, (2) the sector is in a good position to trade carbon removals and credits into a large final emitter cap and trade system, (3) some uncertainties in the policy area remain, (4) the early years of trading are not risk-free, and (5) the risks are being hedged through a number of mechanisms and tools that have already been identified. 18 refs., 3 tabs., 3 figs

    Predators can influence the exchange of carbon dioxide between ecosystems and the atmosphere by altering ecosystem processes such as decomposition and primary production, according to food web theory. Empirical knowledge of such an effect in freshwater systems is limited, but it has been suggested that predators in odd-numbered food chains suppress freshwater carbon dioxide emissions, and predators in even-numbered food chains enhance emissions. Here, we report experiments in three-tier food chains in experimental ponds, streams and bromeliads in Canada and Costa Rica in the presence or absence of fish (Gasterosteus aculeatus) and invertebrate (Hesperoperla pacifica and Mecistogaster modesta) predators. We monitored carbon dioxide fluxes along with prey and primary producer biomass. We found substantially reduced carbon dioxide emissions in the presence of predators in all systems, despite differences in predator type, hydrology, climatic region, ecological zone and level of in situ primary production. We also observed lower amounts of prey biomass and higher amounts of algal and detrital biomass in the presence of predators. We conclude that predators have the potential to markedly influence carbon dioxide dynamics in freshwater systems.

    Highlights: ► CO 2 emissions reduction targeting for existing plant were categorized into three groups. ► Model for CO 2 emissions reduction targeting via combination approach was developed. ► Effect of combination approach onto HEN area efficiency was discussed. ► Proposed execution strategy can avoid HEN area efficiency deterioration. -- Abstract: Carbon emission reduction targeting is an important and effective effort for industry to contribute in controlling greenhouse gases concentration in atmosphere. Graphical approach has been proposed for CO 2 emissions reduction targeting via HEN retrofit and fuel switching. However, it involves potentially time consuming manual procedures and the quality of solutions produced greatly depends on designer’s experience and judgment. Besides, graphical approach hardly account for the cost factor during the design phase, thus potentially generate complex design. This paper introduces an MINLP model for simultaneous CO 2 emissions reduction targeting via fuel switching and HEN retrofit. A sequential model execution was proposed along with the proposed model. The application of the model on a crude preheat train case study has demonstrated its workability to generate optimal solution for targeted CO 2 emissions reduction at minimum payback period.

    In the context of big data age, the energy conservation and emission reduction of transportation is a natural big data industry. The planning, management, decision-making of energy conservation and emission reduction of transportation and other aspects should be supported by the analysis and forecasting of large amounts of data. Now, with the development of information technology, such as intelligent city, sensor road and so on, information collection technology in the direction of the Internet of things gradually become popular. The 3G/4G network transmission technology develop rapidly, and a large number of energy conservation and emission reduction of transportation data is growing into a series with different ways. The government not only should be able to make good use of big data to solve the problem of energy conservation and emission reduction of transportation, but also to explore and use a large amount of data behind the hidden value. Based on the analysis of the basic characteristics and application technology of energy conservation and emission reduction of transportation data, this paper carries out its application research in energy conservation and emission reduction of transportation industry, so as to provide theoretical basis and reference value for low carbon management.

    Biochar has sorption capacity, and can be used to enhance the sequestration of volatile organic contaminants such as pesticides in soil. Chloropicrin (CP) is an important soil fumigant for the production of many fruit and vegetable crops, but its emissions must be minimized to reduce exposure risks and air pollution. The objective of this study was to determine the capacity of biochar to adsorb CP and the effect of biochar amendments to soil on CP emission, concentration in the soil gas phase, degradation in soil and CP bioactivity for controlling soil borne pests. CP emission and concentration in the soil air phase were measured from packed soil columns after fumigant injection at 20-cm depth and application of selected doses of biocharto the surface 5 cm soil. Laboratory incubation and fumigation experiments were conducted to determine the capacity of biochar to adsorb CP, the effects on CP degradation and, separately, CP’s bioactivity on soil borne pests in soil amended with biochar. Biochar amendment at 2% to 5% (w/w) greatly reduced total CP emission losses by 85.7% - 97.7% compared to fumigation without biochar. CP concentrations in the soil gas-phase, especially in the top 5 cm of soil, were reduced within 48 h following application. The half-life of CP decreased from 13.6 h to 6.4 h as the biochar rate increased from 0% to 5%. CP and its metabolite (dichloronitromethane) both degraded more rapidly in pure biochar than in soil. The biochar used in the present study had a maximum adsorption capacity for CP of less than 5 mg g-1. There were no negative effects on pathogen and nematode control when the biochar used in this study was less than 1% (on a weight basis) in soil. Biochar amendment to soil reduced the emissions of CP. CP concentrations in the top 5 cm of soil gas-phase were reduced. CP degradation was accelerated with the addition of biochar. The biochar used in the present study had a low adsorption capacity for CP. There were no negative effects

    Greenhouse gases (GHGs) emissions are becoming significant energy and environmental issues relating to energy consumption in Taiwan. The nation, although not a party to the Montreal Protocol and Kyoto Protocol, has diligently strived to mitigate the emissions and phase out use of the responsible materials. Hydrofluorocarbons (HFCs), which are now mostly used in refrigeration and air conditioning systems, are the main GHGs associated with strong global warming potential. The objective of this paper is to present an overview of the industrial/commercial uses of HFCs in Taiwan. Because of their high impacts on climate change, the description is then centered on estimating the potential emissions of HFCs according to the Intergovernmental Panel on Climate Change (IPCC) method and the governmental organizations responses to the United Nations' Framework Convention on Climate Change (UNFCCC). The regulatory systems relating to HFCs mitigation and energy conservation and energy policies and promotion measures for providing technological assistances and financial incentives in the energy management, resource recovery and HFCs reduction/recycling technologies are also addressed in the paper

    This paper examines the cost structure of certified emission reductions (CERs) through various types of projects under the Clean Development Mechanism (CDM) of the Kyoto Protocol. Using the CDM project data, the costs of CERs and their variation across technology and over time and space are estimated by applying alternative functional forms and specifications. Results show that the average cost of CERs decreases with the project scale and duration, scale and duration effects significantly vary across project types, and there is an upward trend in costs. The results also show that the distribution of the projects in the CDM portfolio or a given location does not strictly follow the relative cost structure, nor does the distribution of the CDM projects in different host countries follow the principle of comparative advantage. More than 84% of the CDM portfolio consists of various energy projects with substantially higher costs of CERs than afforestation and reforestation, industrial and landfill gas reduction, and methane avoidance projects, which are only 12% of all projects. While per unit cost of abatement plays an important role in the bottom-up and top-down models to evaluate emission reduction potential and analyze policy alternatives, the findings contradict the presumption of such models that project investors seek out low-cost opportunities. At the aggregate level, the cost of CER by the projects in Asia and Europe is similar but higher than those hosted in Africa, Americas, and Oceania. Yet more than 83% of the projects in the CDM portfolio are located in Asia; more than 69% of the projects are in China and India alone. China appears to have a comparative advantage (i.e., lowest opportunity cost) in energy efficiency projects, while India has a comparative advantage in hydro power projects and Brazil has a comparative advantage in wind power projects. In contrast, energy efficiency category accounts for only 8% of the CDM projects in China, hydro power

    Every four years the Dutch National Institute of Public Health and the Environment (RIVM) publishes an Environmental Outlook in preparation for the National Environmental Policy Plan (NEPP). The fifth National Environmental Outlook (NEOS) describes developments in the quality of the environment in the Netherlands for 2000-2030 against a background of developments on the European and global scales. The two macro-economic scenarios of the Netherlands Bureau for Economic and Policy Analysis (CPB) used are the European Coordination (EC) scenario and the Global Competition scenario (GC). Consequences for public health, nature and the human physical environment are also indicated. 'Fixed policy' scenarios are used in the Environmental Outlook for the Netherlands. In 'fixed policy' scenarios it is assumed that all policy measures agreed on by the year 2000 will be implemented, but no new measures taken. In this way the Outlook offers baseline scenarios that can be compared with targets and objectives to facilitate the development of new policy. The Fifth National Environmental Outlook was realised with the assistance of many other Dutch research institutes. This background document to NEOS presents estimated levels of energy use, emissions and costs of environmental measures for the 1995-2020 period. The main conclusions are: The environmental problems most difficult to tackle are climate change and noise nuisance. These problems are highly related to energy use and transportation; The policy as presented in the 'Uitvoeringsnota Klimaatbeleid', a document describing the Dutch Kyoto-related climate policy, results in a reduction of greenhouse gases of 15 Mton CO2 equivalents (GS scenario) with respect to the pre-Kyoto policy in 2010. To meet the Kyoto agreements a further reduction of approximately 45 Mton CO2 equivalents is needed. If policies in the 'Uitvoeringsnota Klimaatbeleid' are further instrumentalised and made concrete, an extra reduction of 10 Mton is possible

    Full Text Available A global chemistry-climate model has been used to study the impacts of pollutants released by agriculture on fine-particulate matter (PM2.5, with a focus on Europe, North America, East and South Asia. Simulations reveal that a relatively strong reduction in PM2.5 levels can be achieved by decreasing agricultural emissions, notably of ammonia (NH3 released from fertilizer use and animal husbandry. The absolute impact on PM2.5 reduction is strongest in East Asia, even for small emission decreases. Conversely, over Europe and North America, aerosol formation is not immediately limited by the availability of ammonia. Nevertheless, reduction of NH3 can also substantially decrease PM2.5 concentrations over the latter regions, especially when emissions are abated systematically. Our results document how reduction of agricultural emissions decreases aerosol pH due to the depletion of aerosol ammonium, which affects particle liquid phase and heterogeneous chemistry. Further, it is shown that a 50 % reduction of agricultural emissions could prevent the mortality attributable to air pollution by  ∼ 250 000 people yr−1 worldwide, amounting to reductions of 30, 19, 8 and 3 % over North America, Europe, East and South Asia, respectively. A theoretical 100 % reduction could even reduce the number of deaths globally by about 800 000 per year.

    2013-01-01

    With the current focus of policy action on climate change mitigation, it is important to investigate possible negative side effects of climate change policies on air pollutants. A 34% increase in CO 2 emissions from private cars in Ireland over the period 2000–2008 prompted a change in private car taxation in 2008 to incentivise the purchase of lower CO 2 emitting cars. The impact has been successful and the measure has accelerated the dieselisation of the car fleet. This however, raises an important question, namely how does the dieselisation of the car fleet affect NO x emissions? This paper combines two models to address this question, a car stock model to generate activity data (future composition and activity of Ireland's car stock) and the COPERT model to quantify the NO x emissions generated in the period 2008–2020. Previous analysis shows that the CO 2 taxation policy measure is anticipated to deliver a 7% reduction in private car related CO 2 emissions in 2020 compared with a baseline pre-tax scenario. The results here show that NO x emissions decrease in all scenarios, but a lesser degree of reduction is achieved due to dieselisation, with NO x emissions in the post-tax scenario 28% higher than the pre-tax scenario in 2020. - Highlights: • Irish car tax changed in 2008 to a CO 2 -graduated system. • Change successfully reduced the CO 2 intensity of new cars through dieselization. • However, this has negative consequences for air pollution. • Bottom-up model analyses pre-tax and post-tax NO x to 2020 using COPERT. • NO x projected to be 28% higher in 2020 compared with pre-tax scenario

    Highlights: • DEA is used to evaluate the energy and environmental efficiency of 30 provincial industrial sector in China. • A new DEA-based model is proposed to allocate the CO_2 emissions and energy intensity reduction targets. • The context-dependent DEA is used to characterize the production plans. - Abstract: High energy consumption by the industry of developing countries has led to the problems of increasing emission of greenhouse gases (GHG) (primarily CO_2) and worsening energy shortages. To address these problems, many mitigation measures have been utilized. One major measure is to mandate fixed reductions of GHG emission and energy consumption. Therefore, it is important for each developing country to disaggregate their national reduction targets into targets for various geographical parts of the country. In this paper, we propose a DEA-based approach to allocate China’s national CO_2 emissions and energy intensity reduction targets over Chinese provincial industrial sectors. We firstly evaluate the energy and environmental efficiency of Chinese industry considering energy consumption and GHG emissions. Then, considering the necessity of mitigating GHG emission and energy consumption, we develop a context-dependent DEA technique which can better characterize the changeable production with reductions of CO_2 emission and energy intensity, to help allocate the national reduction targets over provincial industrial sectors. Our empirical study of 30 Chinese regions for the period 2005–2010 shows that the industry of China had poor energy and environmental efficiency. Considering three major geographical areas, eastern China’s industrial sector had the highest efficiency scores while in this aspect central and western China were similar to each other at a lower level. Our study shows that the most effective allocation of the national reduction target requires most of the 30 regional industrial to reduce CO_2 emission and energy intensity, while a

    In this research, the waste tail gas emitted from petrochemical processes, e.g. catalytic reforming unit, catalytic cracking unit and residue desulfurization unit, was recovered and reused as a replacement of natural gas (NG). On-site experimental results show that both the flame length and orange-yellowish brightness decrease with more proportion of waste gas fuel added to the natural gas, and that the adiabatic temperature of the mixed fuel is greater than 1800 o C. A complete replacement of natural gas by the recovered waste gas fuel will save 5.8 x 10 6 m 3 of natural gas consumption, and 3.5 x 10 4 tons of CO 2 emission annually. In addition, the reduction of residual O 2 concentration in flue gases from 4% to 3% will save 1.1 x 10 6 m 3 of natural gas consumption, reduce 43.0% of NO x emission, and 1.3 x 10 3 tons of CO 2 emission annually. Thus, from the viewpoint of the overall economics and sustainable energy policy, recovering the waste tail gas energy as an independent fuel source to replace natural gas is of great importance for saving energy, reducing CO 2 emission reduction, and lowering environmental impact.

    Rate-based emissions policies (like tradable performance standards, TPS) fix average emissions intensity, while cap-and-trade (CAT) policies fix total emissions. This paper shows that unfettered trade between rate-based and cap-and-trade programs always raises combined emissions, except when product markets are related in particular ways. Gains from trade are fully passed on to consumers in the rate-based sector, resulting in more output and greater emissions allocations. We consider several policy options to offset the expansion, including a tax, an 'exchange rate' to adjust for relative permit values, output-based allocation (OBA) for the rate-based sector, and tightening the cap. A range of combinations of tighter allocations could improve situations in both sectors with trade while holding emissions constant

    In the general frame of energy saving, environment protection and the concept of circular economy, the fundamental research on the sintering technology with super deep bed, achieving energy saving and emission reduction, was carried out. At first, the characteristics of the process and exhaust emission in the sintering with super deep bed was mastered through the study of the influence of different bed depths on the sintering process. Then, considering the bed permeability and the fuel combustion, their influence on the sinter yield and quality, their potential for energy saving and emission reduction was studied. The results show that the improvement of the bed permeability and of the fuel combustibility respectively and simultaneously, leads to an improvement of the sintering technical indices, to energy saving and emission reduction in the condition of super deep bed. At 1000 mm bed depth, and taking the appropriate countermeasure, it is possible to decrease the solid fuel consumption and the emission of CO 2 , SO 2 , NO x by 10.08%, 11.20%, 22.62% and 25.86% respectively; and at 700 mm bed depth, it is possible to reduce the solid fuel consumption and the emission of CO 2 , SO 2 , NO x by 20.71%, 22.01%, 58.86% and 13.13% respectively. This research provides the theoretical and technical basis for the new technology of sintering with super deep bed, achieving energy saving and reduction of emission. (authors)

    Implications on the Canadian refining industry of reducing greenhouse gas (GHG) emissions to meet Canada's Kyoto commitment are assessed, based on a plant-level analysis of costs, benefits and economic and competitive impacts. It was determined on the basis of demand estimates prepared by Natural Resources Canada that refining industry carbon dioxide emissions could be as much a 38 per cent higher than 1990 levels in 2010. Achieving a six per cent reduction below 1990 levels from this business-as-usual case is considered a very difficult target to achieve, unless refinery shutdowns occur. This would require higher imports to meet Canada's petroleum products demand, leaving total carbon dioxide emissions virtually unchanged. A range of options, classified as (1) low capital, operating efficiency projects, (2) medium capital, process/utility optimization projects, (3) high capital, refinery specific projects, and (4) high operating cost GHG projects, were evaluated. Of these four alternatives, the low capital or operating efficiency projects were the only ones judged to have the potential to be economically viable. Energy efficiency projects in these four groups were evaluated under several policy initiatives including accelerated depreciation and a $200 per tonne of carbon tax. Result showed that an accelerated depreciation policy would lower the hurdle rate for refinery investments, and could achieve a four per cent reduction in GHG emissions below 1990 levels, assuming no further shutdown of refinery capacity. The carbon tax was judged to be potentially damaging to the Canadian refinery industry since it would penalize cracking refineries (most Canadian refineries are of this type); it would provide further uncertainty and risk, such that industry might not be able to justify investments to reduce emissions. The overall assessment is that the Canadian refinery industry could not meet the pro-rata Kyoto GHG reduction target through implementation of economically

    2012-01-01

    California’s target for reducing economy-wide greenhouse gas (GHG) emissions is 80% below 1990 levels by 2050. We develop transition scenarios for meeting this goal in California’s transportation sector, with focus on light-duty vehicles (LDVs). We explore four questions: (1) what options are available to reduce transportation sector GHG emissions 80% below 1990 levels by 2050; (2) how rapidly would transitions in LDV markets, fuels, and travel behaviors need to occur over the next 40 years; (3) how do intermediate policy goals relate to different transition pathways; (4) how would rates of technological change and market adoption between 2010 and 2050 impact cumulative GHG emissions? We develop four LDV transition scenarios to meet the 80in50 target through a combination of travel demand reduction, fuel economy improvements, and low-carbon fuel supply, subject to restrictions on trajectories of technological change, potential market adoption of new vehicles and fuels, and resource availability. These scenarios exhibit several common themes: electrification of LDVs, rapid improvements in vehicle efficiency, and future fuels with less than half the carbon intensity of current gasoline and diesel. Availability of low-carbon biofuels and the level of travel demand reduction are “swing factors” that influence the degree of LDV electrification required. - Highlights: ► We model change in California LDVs for deep reduction in transportation GHG emissions. ► Reduced travel demand, improved fuel economy, and low-carbon fuels are all needed. ► Transitions must begin soon and occur quickly in order to achieve the 80in50 goal. ► Low-C biofuel supply and travel demand influence the need for rapid LDV electrification. ► Cumulative GHG emissions from LDVs can differ between strategies by up to 40%.

    AIM (Asian-Pacific Integrated Model) has been developed for predicting greenhouse gas emissions and evaluating policy measures to reduce them. Two socio-economic scenarios were assumed and CO 2 emissions were predicted based on these scenarios and policy intervention assumptions. It is found that mitigating CO 2 emissions without scaling back productive activities or standards of living in Japan is possible. However, if one relies on the market mechanism alone, it cannot be done. The analysis has shown that it is essential to introduce new policies and measures such as carbon tax and subsidies. (author)

    2007-01-01

    In this dissertation, Ulrich Straumann of the Swiss Federal Institute of Technology in Zurich, Switzerland, discusses the reduction of sound emissions from overhead power lines. Corona-discharges occur during wet weather or when foggy or icing conditions prevail. Apart from these wide-band crackling noises, low-frequency, tonal emissions also occur. The CONOR (Corona Noise Reduction) project examined these emissions at a frequency of twice the mains frequency and looked for economically feasible solutions to the problems caused by them. The source of these emissions and the mechanisms causing them are discussed. Also, ways of calculating their strength are presented. The effects of varying cable geometry and construction are discussed, as are hydrophilic coatings that could be used to reduce sound emissions.

    1999-01-01

    If levels of carbon dioxide in the atmosphere are to be stabilized over the next 50 years, net emissions from the use of fossil fuels have to be reduced. One concept worth exploring is the removal of carbon dioxide from plant flue gases and disposing of it in a manner that sequesters it from the atmosphere. A number of technologies, which are either commercially available or under development, promise to make this concept viable. The question of where to dispose of the carbon dioxide removed is not the limiting factor, given the potential for use in enhanced hydrocarbon production as well as other geological disposal options. In the longer term, fossil fuel use will significantly decline, but these extraction and sequestration technologies can provide the time for the transition to take place in a manner which causes least impact to the economies of the world.

  8. System-wide and Superemitter Policy Options for the Abatement of Methane Emissions from the U.S. Natural Gas System

    2017-12-01

    This work assesses trade-offs between system-wide and superemitter policy options for reducing methane emissions from compressor stations in the U.S. transmission and storage system. Leveraging recently collected national emissions and activity data sets, we developed a new process-based emissions model implemented in a Monte Carlo simulation framework to estimate emissions for each component and facility in the system. We find that approximately 83% of emissions, given the existing suite of technologies, have the potential to be abated, with only a few emission categories comprising a majority of emissions. We then formulate optimization models to determine optimal abatement strategies. Most emissions across the system (approximately 80%) are efficient to abate, resulting in net benefits ranging from 160M to 1.2B annually across the system. The private cost burden is minimal under standard and tax instruments, and if firms market the abated natural gas, private net benefits may be generated. Superemitter policies, namely, those that target the highest emitting facilities, may reduce the private cost burden and achieve high emission reductions, especially if emissions across facilities are highly skewed. However, detection across all facilities is necessary regardless of the policy option and there are nontrivial net benefits resulting from abatement of relatively low-emitting sources.

    Climate policies overlapping a cap-and-trade scheme are generally considered not to change domestic emissions. In a two-sector general equilibrium model where only one sector is covered by a cap, we find that such policies do have a net impact on carbon emissions through inter-sectoral leakage. Promotion of renewable energy reduces emissions if tax-funded, but can increase emissions if funded by a levy on electricity. Replacing fossil fuels by electricity in uncapped sectors (e.g. power-to-he...

  10. The impact of the economic crisis and policy actions on GHG emissions from road transport in Spain

    International Nuclear Information System (INIS)

    Sobrino, Natalia; Monzon, Andres

    2014-01-01

    Road traffic is the greatest contributor to the carbon footprint of the transport sector and reducing it has become one of the main targets of sustainable transport policies. An analysis of the main factors influencing greenhouse gas (GHG) emissions is essential for designing new energy- and environmentally efficient strategies for the road transport. This paper addresses this need by (i) identifying factors which influence the carbon footprint, including traffic activity, fuel economy and socioeconomic development; and (ii) proposing a methodological framework which uses Modified Laspeyres Index decomposition to analyze the effect of important drivers on the changes in emissions of road transport in Spain during the period from 1990 to 2010. The results demonstrate that the country's economic growth has been closely linked to the rise in GHG emissions. The innovative contribution of this paper is the special analysis of the changes in mobility patterns and GHG emissions during the economic crisis, when, for the first time, Spanish road traffic emissions decreased. The reduction of road transport and improved energy efficiency has been powerful contributors to this decrease, demonstrating the effectiveness of energy-saving measures. On the basis of this analysis, several tailored policy recommendations have been suggested for future implementation. - Highlights: • Drivers contributing to GHG emissions of road transport are identified and analyzed. • Decomposition analysis based on Modified Laspeyres Index (MLI) is applied to the Spanish case. • Economic crisis and changes in mobility patterns and GHG emissions are analyzed. • Policies for the decarbonization of road transport are recommended

    This article is based on the observation that, up until now, corporate investment has been limited in clean technologies despite the will of governmental authorities to stimulate them in order to cope with the demands of sustainable development. The paper deals with the issue of the development of clean technologies and the role of regulations as clean technology promoters. It tries to apprehend the characteristics and specificity of clean technology from both an empirical and a theoretical point of view, so as to understand which are the most favourable (or inversely, the most detrimental) conditions for their development. We use case studies concerning the reduction of volatile organic compound (VOC) emissions in the chemical and metallurgical industries. These two examples highlight the problems created by the shift from a 'with-solvent paradigm' to a 'solvent-free paradigm' and the way clean technology trajectories may spread within such paradigms. We show that the problem of clean technology development primarily resides in some factors that impede technological adoption, although a strong and mixed incentives framework prevails. Such impediments are sector-specific, leading to different clean technology trajectories among sectors and indicating areas of sectoral intervention that could become the cornerstones of complementary technology policy.

    2016-01-01

    Highlights: • A new industrial modelling approach in a whole energy systems model is developed. • The contribution of UK industry to long-term energy policy targets is analysed. • Emission reductions of up to 77% can be achieved in the UK industry until 2050. • The UK industry sector is essential for achieving the overall efficiency commitments. • UK industry can make a moderate contribution to the expansion of renewable energies. - Abstract: This paper evaluates the critical contribution of the industry sector to long-term decarbonisation, efficiency and renewable energy policy targets. Its methodological novelty is the incorporation of a process-oriented modelling approach based on a comprehensive technology database for the industry sector in a national energy system model for the UK (UKTM), allowing quantification of the role of both decarbonisation of upstream energy vectors and of mitigation options in the industrial sub-categories. This enhanced model is then applied in a comparative policy scenario analysis that explores various target dimensions on emission mitigation, renewable energy and energy efficiency at both a national and European level. The results show that ambitious emission cuts in the industry sector of up to 77% until 2050 compared to 2010 can be achieved. Moreover, with a reduction in industrial energy demand of up to 31% between 2010 and 2050, the sector is essential for achieving the overall efficiency commitments. The industry sector also makes a moderate contribution to the expansion of renewable energies mostly through the use of biomass for low-temperature heating services. However, additional sub-targets on renewable sources and energy efficiency need to be assessed critically, as they can significantly distort the cost-efficiency of the long-term mitigation pathway.

    The major problem of the energy production in oil refineries is the high emission of CO2 in China. The fluid catalytic cracking unit (FCC) is the key source of carbon emission in the oil refineries. According to the statistical data, the carbon emission of FCC unit accounts for more than 31% for the typical oil refineries. The carbon flow of FCC in the typical Chinese oil refineries were evaluated and analysed, which aimed at the solution of CO2 emission reduction. The method of substances flow analysis (SFA) and the mathematical programming were used to evaluate the carbon metabolism and optimize the carbon emission. The results indicated that the combustion emission of the reaction-regeneration subsystem (RRS) was the major source of FCC. The quantity of CO2 emission of RSS was more than 90%. The combustion efficiency and the amount of residual oil affected the carbon emission of RRS most according to the optimized analysis of carbon emission reduction. Moreover, the fractionation subsystem (TFS) had the highest environmental efficiency and the absorption-stabilization subsystem (ASS) had the highest resource efficiency (approximately to 1) of carbon.

  14. Process industry energy retrofits: the importance of emission baselines for greenhouse gas reductions

    2004-01-01

    Fuel combustion for heat and/or electric power production is often the largest contributor of greenhouse gas (GHG) emissions from an industrial process plant. Economically feasible options to reduce these emissions include fuel switching and retrofitting the plant's energy system. Process integration methods and tools can be used to evaluate potential retrofit measures. For assessing the GHG emissions reduction potential for the measures considered, it is also necessary to define appropriate GHG emission baselines. This paper presents a systematic GHG emission calculation method for retrofit situations including improved heat exchange, integration of combined heat and power (CHP) units, and combinations of both. The proposed method is applied to five different industrial processes in order to compare the impact of process specific parameters and energy market specific parameters. For potential GHG emission reductions the results from the applied study reveal that electricity grid emissions are significantly more important than differences between individual processes. Based on the results of the study, it is suggested that for sustainable investment decision considerations a conservative emission baseline is most appropriate. Even so, new industrial CHP in the Northern European energy market could play a significant role in the common effort to decrease GHG emissions

    In the present study, non-edible seed oil namely raw neem oil was converted into biodiesel using transesterification process. In the experimentation, two biodiesel blends were prepared namely B25 (25% neem oil methyl ester with 75% of diesel) and B50 (50% neem oil methyl ester with 50% diesel). Urea-based selective catalytic reduction (SCR) technique with catalytic converter (CC) was fixed in the exhaust tail pipe of the engine for the reduction of engine exhaust emissions. Initially, the engine was operated with diesel as a working fluid and followed by refilling of biodiesel blends B25 and B50 to obtain the baseline readings without SCR and CC. Then, the same procedure was repeated with SCR and CC technique for emission reduction measurement in diesel, B25 and B50 sample. The experimental results revealed that the B25 blend showed higher break thermal efficiency (BTE) and exhaust gas temperature (EGT) with lower break-specific fuel consumption (BSFC) than B50 blend at all loads. On comparing with biodiesel blends, diesel experiences increased BTE of 31.9% with reduced BSFC of 0.29 kg/kWh at full load. A notable emission reduction was noticed for all test fuels in SCR and CC setup. At full load, B25 showed lower carbon monoxide (CO) of 0.09% volume, hydrocarbon (HC) of 24 ppm, and smoke of 14 HSU and oxides of nitrogen (NOx) of 735 ppm than diesel and B50 in SCR and CC setup. On the whole, the engine with SCR and CC setup showed better performance and emission characteristics than standard engine operation.

    This article analyses, from a human rights' approach, a group of social programmes implemented in Argentina from the year 2002, at the time of the biggest socioeconomic crisis that the country has suffered in the last decades. The main characteristics of the programmes are reviewed, and their anti-poverty strategy, along with design and implementation, are evaluated in relation to human rights. An assessment is also made of the existence of mechanisms for citizens to present claims. Finally, a set of recommendations are made to facilitate the adaptation of the programmes analysed to the duties the State of Argentina has as result of its adherence to international laws on human rights. The analytical methodology proposed by this article could be applied to other policy areas.

    1991-01-01

    A new approach for state- and utility-level analysis of the cost and regional economic impacts of strategies for reducing utility SO 2 emissions is summarized and applied to Ohio. The methodology is based upon probabilistic production costing and economic input-output analysis. It is an improvement over previous approaches because it: (1) accurately models random outages of generating units, 'must-run' constraints on unit output, and the distribution of power demands; and (2) runs quickly on a microcomputer and yet considers the entire range of potential control strategies from a systems perspective. The input-output analysis considers not only the economic effects of utility fuel use and capital investment, but also those of increased electric rates. Two distinct strategies are found to be most attractive for Ohio. The first, more flexible one, consists of emissions dispatching (ED) alone to meet short run emissions reduction targets. A 75 percent reduction can then be achieved by the turn of the century by combining ED and fuel switching (FS) with flue gas desulfurization, limestone injection multistage burners, and physical coal cleaning at selected plants. The second is a scrubber-based strategy which includes ED. By the year 2000, energy conservation becomes a cost effective component of these strategies. In order to minimize compliance costs, acid rain legislation which facilitates emission trading and places regional tonnage limits on emissions is desirable

    International Nuclear Information System (INIS)

    2013-01-01

    This years' annual Forum is held twenty-two years in a row. Analysing the energy development to 2050 takes into consideration the nature and complexity of the energy development, a long period of preparing plants and facilities, a long service life of plants, dimensions of technological development and continuous growth of energy demand. New reasons for a long-term observation of the energy development, at least by 2050, are climate change and radical reducing emissions of carbon dioxide and other greenhouse gases according to the EU Energy Policy to 2050. The impact of permitted level of carbon dioxide emissions on the energy production and consumption is drastic and fundamentally changes the structure of energy production and consumption. The new legal and economical approach as well as the new technological development and and political determination are required for the implementation of energy policy which should lead to radical reduction of carbon dioxide emissions. The time is also an important factor because postponement of defining the new approach of energy policy decreases the possibility of its realisation. An additional argument for a new technological development is the mobilization of the science and industry for achieving that new step in technological development. This development is required in order to develop the energy industry without or with minimal greenhouse gas emissions. Furthermore, it is very important for renewable energy, at the carbon dioxide capture and storage, at the energy efficiency in the whole range of activities, from the production, transmission and distribution to the consumption of devices and equipment used by consumers, at smart grids, at the energy storage and vehicles. Reducing the energy consumption in buildings is energy, economical, architectual and organizational project which has to include every commercial and residential building. It is important to eliminate all disadvantages that incurred in the period when

    Buildings consume nearly 40% of primary energy production globally. Certified green buildings substantially reduce energy consumption on a per square foot basis and they also focus on indoor environmental quality. However, the co-benefits to health through reductions in energy and concomitant reductions in air pollution have not been examined.We calculated year by year LEED (Leadership in Energy and Environmental Design) certification rates in six countries (the United States, China, India, Brazil, Germany, and Turkey) and then used data from the Green Building Information Gateway (GBIG) to estimate energy savings in each country each year. Of the green building rating schemes, LEED accounts for 32% of green-certified floor space and publically reports energy efficiency data. We employed Harvard's Co-BE Calculator to determine pollutant emissions reductions by country accounting for transient energy mixes and baseline energy use intensities. Co-BE applies the social cost of carbon and the social cost of atmospheric release to translate these reductions into health benefits. Based on modeled energy use, LEED-certified buildings saved $7.5B in energy costs and averted 33MT of CO 2 , 51 kt of SO 2 , 38 kt of NO x , and 10 kt of PM 2.5 from entering the atmosphere, which amounts to $5.8B (lower limit = $2.3B, upper limit = $9.1B) in climate and health co-benefits from 2000 to 2016 in the six countries investigated. The U.S. health benefits derive from avoiding an estimated 172-405 premature deaths, 171 hospital admissions, 11,000 asthma exacerbations, 54,000 respiratory symptoms, 21,000 lost days of work, and 16,000 lost days of school. Because the climate and health benefits are nearly equivalent to the energy savings for green buildings in the United States, and up to 10 times higher in developing countries, they provide an important and previously unquantified societal value. Future analyses should consider these co-benefits when weighing policy

We employ a conservative cost-effectiveness methodology with a zero net cost threshold. Our urban transport strategy (with cleaner vehicles and increased active travel......) brings important health co-benefits and is likely to be strongly cost-effective; our food and agriculture strategy (based on abatement technologies and reduction in livestock production) brings worthwhile health co-benefits, but is unlikely to eliminate net costs unless new technological measures...... to achieve future emission targets and longer-term benefits from GHG reduction. Cost-effectiveness of GHG strategies is likely to require technological mitigation interventions and/or demand-constraining interventions with important health co-benefits and other efficiency-enhancing policies that promote...

    2006-07-01

    Major polluters of man's environment are thermal power stations (TPS) and power plants, which discharge into the atmosphere the basic product of carbon fuel combustion, CO2, which results in a build-up of the greenhouse effect and global warm-up of our planet's climate. This paper is intended to show that the way to attain environmental safety of the TPS and to abide by the decisions of the Kyoto Protocol lies in raising the efficiency of the heat power stations and reducing their fuel consumption by using nonconventional thermal cycles. Certain equations have been derived to define the quantitative interrelationship between the growth of efficiency of the TPS, decrease in fuel consumption and reduction of discharge of dust, fuel combustion gases, and heat into the environment. New ideas and new technological approaches that result in raising the efficiency of the TPS are briefly covered: magneto-hydrodynamic resonance, the Kalina cycle, and utilizing the ambient heat by using, as the working medium, low-boiling substances.

    Dietary salt intake has been causally linked to high blood pressure and increased risk of cardiovascular events. Cardiovascular disease causes approximately 35% of total UK deaths, at an estimated annual cost of £30 billion. The World Health Organization and the National Institute for Health and Care Excellence have recommended a reduction in the intake of salt in people's diets. This study evaluated the cost-effectiveness of four population health policies to reduce dietary salt intake on an English population to prevent coronary heart disease (CHD). The validated IMPACT CHD model was used to quantify and compare four policies: 1) Change4Life health promotion campaign, 2) front-of-pack traffic light labeling to display salt content, 3) Food Standards Agency working with the food industry to reduce salt (voluntary), and 4) mandatory reformulation to reduce salt in processed foods. The effectiveness of these policies in reducing salt intake, and hence blood pressure, was determined by systematic literature review. The model calculated the reduction in mortality associated with each policy, quantified as life-years gained over 10 years. Policy costs were calculated using evidence from published sources. Health care costs for specific CHD patient groups were estimated. Costs were compared against a "do nothing" baseline. All policies resulted in a life-year gain over the baseline. Change4life and labeling each gained approximately 1960 life-years, voluntary reformulation 14,560 life-years, and mandatory reformulation 19,320 life-years. Each policy appeared cost saving, with mandatory reformulation offering the largest cost saving, more than £660 million. All policies to reduce dietary salt intake could gain life-years and reduce health care expenditure on coronary heart disease.

  7. Is faster economic growth compatible with reductions in carbon emissions? The role of diminished population growth

    We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions, accounting for the fact that changes in fertility patterns affect carbon emissions through three channels: total population, the age structure of the population, and economic output. Our analysis proceeds in two steps. First, we estimate the elasticity of carbon emissions with respect to population and income per capita in an unbalanced yearly panel of cross-country data from 1950-2010. We demonstrate that the elasticity with respect to population is nearly seven times larger than the elasticity with respect to income per capita and that this difference is statistically significant. Thus, the regression results imply that 1% slower population growth could be accompanied by an increase in income per capita of nearly 7% while still lowering carbon emissions. In the second part of our analysis, we use a recently constructed economic-demographic model of Nigeria to estimate the effect of lower fertility on carbon emissions, accounting for the impacts of fertility on population growth, population age structure, and income per capita. We find that by 2100 C.E. moving from the medium to the low variant of the UN fertility projection leads to 35% lower yearly emissions and 15% higher income per capita. These results suggest that population policies could be part of the approach to combating global climate change.

    Taking into account the greenhouse gas emissions for Colombia in year 2010, different options for reduction of GHG emissions were considered. Twenty-four options were evaluated from economical and technical points of view, with a total reduction potential of 31.7 M ton/ year of CO 2 equivalent. About 75% of this potential could be developed in the forestry sector and 25% in energy projects. If the proposed measures can to be implemented, the country's emissions will be 143.5 M ton/year of co2 by 2010: this means that Colombia will have lowered its emissions not only to the 1990 level but down to 14% below this level

    Reducing greenhouse gas emissions is now an urgent priority. Systems control theory, and in particular feedback control, can be helpful in designing policies that achieve sustainable levels of emissions of CO 2 (and other greenhouse gases) while minimizing the impact on the economy, and at the same time explicitly addressing the high levels of uncertainty associated with predictions of future emissions. In this paper, we describe preliminary results for an approach where model predictive control (MPC) is applied to a model of the UK economy (UK 4see model) as a test bed to design sustainable policies for greenhouse gas emissions. Using feedback control, the policies are updated on the basis of the actual emissions, rather than on the predicted level of emissions. The basic structure and principle of the UK 4see model is described and its implementation in Simulink is presented. A linearized state space model is obtained and model predictive control is applied to design policies for CO 2 emissions. Simulation results are presented to demonstrate the effectiveness of the proposed method. The preliminary results obtained in this paper illustrate the strength of the proposed design approach and form the basis for future research on using systems control theory to design optimal sustainable policies

    Highlights: ► Energy demand modeling in Thai road transportation sector was developed. ► Such model was used to assess environment impact by ethanol bus technology (ED95). ► Ethanol bus technology (ED95) shows beneficial impacts to Thailand. ► Increase in ethanol demand and decrease in GHG emission in Thailand by ethanol bus. ► Ethanol bus (ED95) has been successfully demonstrated in Thailand. -- Abstract: Over decades, Thailand energy consumption has been concentrated in three main sectors, namely manufacturing, power and transportation. Energy consumption in transportation sector has also been dominated by road transport due to limited coverage by rail and water transportation. Hence, road transport has been a major contributor for greenhouse gas emission in Thailand over recent years. Along with global warming concern throughout the world, Thailand has taken various adaptation and mitigation measures, especially the strong policy push to use carbon–neutral biofuel in transportation sector due to Thailand competitive advantage in agriculture sector. National Renewable Energy Plan (2008–2022) has set challenging targets of 9 and 4.5 million liters/day of ethanol and biodiesel consumption by 2022, respectively. Various blends of ethanol in gasoline (10%, 20% and 85%) and biodiesel in diesel (up to 5%) have been commercially available. However, since current consumption of diesel is twice as much of gasoline, ethanol blend in gasoline would widen the imbalance consumption of gasoline and diesel. The present study however offers an insight into a possibility to use ethanol as diesel substitute. A case study of ethanol bus technology was investigated by recourse to energy demand modeling. Necessary data, such as a number of vehicles (NVs) for various vehicle types, vehicle kilometer of travel (VKT) and fuel economy (FE) were collected, with reasonable assumptions made for those unavailable data, to construct predicative energy demand model.

    2004-01-01

    This paper presents the concept and methodologies behind the development of a health effects priority ranking tool for the reduction of air emissions from oil refineries. The Health Effects Indicators Decision Index- Versions 2 (Heidi II) was designed to assist policy makers in prioritizing air emissions reductions on the basis of estimated risk to human health. Inputs include facility level rankings of potential health impacts associated with carcinogenic air toxics, non-carcinogenic air toxics and criteria air contaminants for each of the 20 refineries in Canada. Rankings of estimated health impacts are presented on predicted incidence of health effects. Heidi II considers site-specific annual pollutant emission data, ambient air concentrations associated with releases and concentration response functions for various types of health effects. Additional data includes location specific background air concentrations, site-specific population densities, and the baseline incidence of different health effects endpoints, such as cancer, non-cancer illnesses and cardiorespiratory illnesses and death. Air pollutants include the 29 air toxics reported annually in Environment Canada's National Pollutant Release Inventory. Three health impact ranking outputs are provided for each facility: ranking of pollutants based on predicted number of annual cases of health effects; ranking of pollutants based on simplified Disability Adjusted Life Years (DALYs); and ranking of pollutants based on more complex DALYs that consider types of cancer, systemic disease or types of cardiopulmonary health effects. Rankings rely on rough statistical estimates of predicted incidence rates for health endpoints. The models used to calculate rankings can provide useful guidance by comparing estimated health impacts. Heidi II has demonstrated that it is possible to develop a consistent and objective approach for ranking priority reductions of air emissions. Heidi II requires numerous types and

    The 2006 California Global Warming Solutions Act calls for reducing greenhouse gas (GHG) emissions to 1990 levels by 2020. Meeting this target will require action from all sectors of the California economy, including industry. The industrial sector consumes 25% of the energy used and emits 28% of the carbon dioxide (CO{sub 2}) produced in the state. Many countries around the world have national-level GHG reduction or energy-efficiency targets, and comprehensive programs focused on implementation of energy efficiency and GHG emissions mitigation measures in the industrial sector are essential for achieving their goals. A combination of targets and industry-focused supporting programs has led to significant investments in energy efficiency as well as reductions in GHG emissions within the industrial sectors in these countries. This project has identified program and policies that have effectively targeted the industrial sector in other countries to achieve real energy and CO{sub 2} savings. Programs in Ireland, France, The Netherlands, Denmark, and the UK were chosen for detailed review. Based on the international experience documented in this report, it is recommended that companies in California's industrial sector be engaged in a program to provide them with support to meet the requirements of AB32, The Global Warming Solution Act. As shown in this review, structured programs that engage industry, require members to evaluate their potential efficiency measures, plan how to meet efficiency or emissions reduction goals, and provide support in achieving the goals, can be quite effective at assisting companies to achieve energy efficiency levels beyond those that can be expected to be achieved autonomously.

    CO 2 emissions from maritime transport represent 3.3% of the world's total CO 2 emissions and are forecast to increase by 150%–250% by 2050, due to increased freight volumes (). Fulfilling anticipated climate requirements () could require the sector to reduce emissions per freight unit by a factor of five or six. The International Maritime Organization (IMO) is currently debating technical, operational and market-based measures for reducing greenhouse gas emissions from shipping. This paper also investigates the effects of economies of scale on the direct emissions and costs of maritime transport. We compared emissions from the current fleet (2007), with what can be achieved by increasing average vessel size. The comparison is based on the 2007 levels of trade and predictions for 2050. The results show that emissions can be reduced by up to 30% at a negative abatement cost per ton of CO 2 by replacing the existing fleet with larger vessels. Replacing the whole fleet might take as long as 25 years, so the reduction in emissions will be achieved gradually as the current fleet is renewed. - Highlights: ► We investigate the effects of economy of scale for reduction of GHG emissions from shipping. ► Model includes both cost and emission as function of vessel size and type. ► Model is based on operational patterns as of today for the different vessel types and sizes. ► Comparison is based on actual 2007 tonnages and foreseen 2050 levels of trading. ► Results shows that emissions can be reduced by 25%–30% at a negative abatement cost.

    The report provides options for how to achieve a 30% reduction in greenhouse gas emissions, in the EU, from 1990 to 2020. The EU has agreed a set of goals (objectives) and related instruments for 2020. The most significant objectives are the 20% or 30% reduction of greenhouse gases (all emissions, both within and outside the Emissions Trading System), the 20% improvement of energy efficiency and the 20% of renewable energy use by 2020. The stringency of the instruments used to reach these goals, must be set carefully to ensure overall consistency. Particularly after the economic crisis of 2008/2009, the Climate and Energy Package has to be 'tuned' again to be fully consistent, e.g. fast take up of renewable energy and fewer emissions due to the recession may cause an over-allocation in the EU-ETS.

    The impact of global warming has received much international attention in recent decades. To meet climate-change mitigation targets, environmental policy instruments have been designed to transform the way goods and services are produced as well as alter consumption patterns. The government of Malaysia is strongly committed to reducing CO 2 gas emissions as a proportion of GDP by 40% from 2005 levels by the year 2020. This study evaluates the economy-wide impacts of implementing two different types of CO 2 emission abatement policies in Malaysia using market-based (imposing a carbon tax) and command-and-control mechanism (sectoral emission standards). The policy simulations conducted involve the removal of the subsidy on petroleum products by the government. A carbon emission tax in conjunction with the revenue neutrality assumption is seen to be more effective than a command-and-control policy as it provides a double dividend. This is apparent as changes in consumption patterns lead to welfare enhancements while contributing to reductions in CO 2 emissions. The simulation results show that the production of renewable energies is stepped up when the imposition of carbon tax and removal of the subsidy is augmented by revenue recycling. This study provides an economy-wide assessment that compares two important tools for assisting environment policy makers evaluate carbon emission abatement initiatives in Malaysia.

    Industrial producers are concerned that Canada's decision to ratify the Kyoto Protocol will have a negative impact on competitiveness programs with its main trading partner, the United States, which has not ratified the Protocol. This paper discusses the concerns expressed by Canadian industrial producers regarding the negative impact of Canada's proposed policy actions to lower carbon dioxide equivalent emissions by 100 Mt, of which 55 Mt are to be realized by large industrial emitters such as oil and gas production, electricity generation from fossil fuels, and a few heterogeneous industries. The power generators' share is approximately 20 Mt. In response to these concerns, the Government of Canada has proposed a ceiling on the price of emissions permits paid by industrial users. It has proposed that no measure that costs more than $15 per tonne of carbon dioxide equivalent should be undertaken by industries. In addition, Canadian industries will not be required to make carbon dioxide equivalent emissions reductions that exceed 15 per cent of their emissions associated with the business as usual scenario in 2010. This study evaluated how such a scheme would affect electricity production and trade between Ontario, Quebec, New Brunswick, New England and New York. It was shown that the scheme has nearly no influence on electricity production and trade flows. As such, it is very effective in protecting the competitive position of electricity products, but it does little to reduce greenhouse gases. 4 refs., 14 tabs., 1 fig

    Globally, the cement industry accounts for approximately 5 percent of current anthropogenic carbon dioxide (CO{sub 2}) emissions. World cement demand and production are increasing significantly, leading to an increase in this industry's absolute energy use and CO{sub 2} emissions. Development of new energy-efficiency and CO{sub 2} emission-reduction technologies and their deployment in the market will be key for the cement industry's mid- and long-term climate change mitigation strategies. This report is an initial effort to compile available information on process description, energy savings, environmental and other benefits, costs, commercialization status, and references for emerging technologies to reduce the cement industry's energy use and CO{sub 2} emissions. Although studies from around the world identify a variety of sector-specific and cross-cutting energy-efficiency technologies for the cement industry that have already been commercialized, information is scarce and/or scattered regarding emerging or advanced energy-efficiency and low-carbon technologies that are not yet commercialized. This report consolidates available information on nineteen emerging technologies for the cement industry, with the goal of providing engineers, researchers, investors, cement companies, policy makers, and other interested parties with easy access to a well-structured database of information on these technologies.

  3. Carbon emissions reduction potential in the US chemicals and pulp and paper industries by applying CHP technologies

    1999-01-01

    The chemical and the pulp/paper industries combined provide 55% of CHP generation in the US industry. Yet, significant potential for new CHP capacities exists in both industries. From the present steam consumption data, the authors estimate about 50 GW of additional technical potential for CHP in both industries. The reduced carbon emissions will be equivalent to 44% of the present carbon emissions in these industries. They find that most of the carbon emissions reductions can be achieved at negative costs. Depending on the assumptions used in calculations, the economic potential of CHP in these industries can be significantly lower, and carbon emissions mitigation costs can be much higher. Using sensitivity analyses, they determine that the largest effect on the CHP estimate have the assumptions in the costs of CHP technology, in the assumed discount rates, in improvements in efficiency of CHP technologies, and in the CHP equipment depreciation periods. Changes in fuel and electricity prices and the growth in the industries' steam demand have less of an effect. They conclude that the lowest carbon mitigation costs are achieved with the CHP facility is operated by the utility and when industrial company that owns the CHP unit can sell extra electricity and steam to the open wholesale market. Based on the results of the analyses they discuss policy implications

    Under the Canadian Environmental Protection Act benzene has been designated as toxic, and after gasoline combustion, the natural gas extraction industry is the largest source of benzene emissions to the environment. The study's objective is to present a profile of the natural gas industry and to analyze the costs to the private sector of complying with the various benzene reduction targets. Also outlined is a profile of the natural gas extraction industry. A description is included of the method used to extrapolate the results obtained from the sample of 370 sites to the industry as a whole. Two scenarios studied are described in section four including: (1) scenario one in which the environmental requirements would have to be applied across-the-board to all emitting sites, which would have to comply with maximum benzene reductions, and (2) scenario two in which the environmental requirements would only be applied to high-emission sites, which would have to comply with specific requirements. A compilation is made in the fifth section for each scenario of the cost to the industry and the benzene emission reductions for each scenario for the sample of 370 sites to the industry as a whole. The aim of developing the two scenarios used to analyze various benzene emissions reduction levels at the sample of 370 sites was to determine: capital costs required, additional annual costs as additional annual operating costs plus annualized capital costs, number of sites affected, and total benzene reductions expressed in tonnes per year. 10 tabs

    Estimating potential of CO 2 emission reduction of non-capture CO 2 utilization (NCCU) technology was evaluated. NCCU is sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue gas. For the estimating the CO 2 emission reduction, process simulation using process simulator (PRO/II) based on a chemical plant which could handle CO 2 of 100 tons per day was performed, Also for the estimation of the indirect CO 2 reduction, the solvay process which is a conventional technology for the production of sodium carbonate/sodium bicarbonate, was studied. The results of the analysis showed that in case of the solvay process, overall CO 2 emission was estimated as 48,862 ton per year based on the energy consumption for the production of NaHCO 3 (7.4 GJ/tNaHCO 3 ). While for the NCCU technology, the direct CO 2 reduction through the CO 2 carbonation was estimated as 36,500 ton per year and the indirect CO 2 reduction through the lower energy consumption was 46,885 ton per year which lead to 83,385 ton per year in total. From these results, it could be concluded that sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue was energy efficient and could be one of the promising technology for the low CO 2 emission technology.

    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

    Distillation systems are energy-intensive processes, and consequently contribute significantly to the greenhouse gases emissions (e.g. carbon dioxide (CO 2 ). A simple model for the estimation of CO 2 emissions associated with operation of heat-integrated distillation systems as encountered in refineries is introduced. In conjunction with a shortcut distillation model, this model has been used to optimize the process conditions of an existing crude oil atmospheric tower unit aiming at minimization of CO 2 emissions. Simulation results indicate that the total CO 2 emissions of the existing crude oil unit can be cut down by 22%, just by changing the process conditions accordingly, and that the gain in this respect can be doubled by integrating a gas turbine. In addition, emissions reduction is accompanied by substantial profit increase due to utility saving and/or export

    This paper describes a computer simulation analysis of carbon dioxide emissions in the electric power system in the western United States. Legislation at both the state and federal level would impose a price on emissions via cap-and-trade in allowances for carbon dioxide emissions. The simulation scenarios for the western system indicate that dramatic reductions in emissions are possible with generating technologies that exist today. Wind and biomass generators play a key role even with conservative assumptions about their future costs. In contrast, generation from advanced technologies provide only a minor contribution by the year 2025. These scenarios provide support to those who argue that the US should move expeditiously to put a price on carbon dixoide emissions
