The recent debate about the use of economic instruments aiming at achieving the GHG goals led to a number of important insights and conclusions. However, the implementation of these instruments is still rather weak. One reason is that the proposed GHG solutions (particularly CO 2 -taxes) are faced with some ambiguities and shortcomings, which require further analysis and discussion. Another reason is that any democratic government has problems to solve problems being identified through scientific analyses but not through daily experience. Any progress in implementing GHG policies requires to convince the larger public about the necessity of an active GHG policy and the unavoidability of costs associated to this policy. In this dilemma situation the change to implement GHG strategies can be improved by a sophisticated combination of voluntary agreements and monetary as well as non-monetary incentives to environmental innovations. According to the game theoretical view, voluntary agreements can't perform better than CO 2 -taxes that will be implemented in case of non-compliance. The paper argues that voluntary agreements can improve the credibility of governmental threats to implement hard measures at a later time. Still voluntary agreement s alone are negligible with respect to GHG emission reductions beyond business as usual. But they may be useful for focusing private business plans on ecological innovations. As far as such innovations become feasible they contribute to the low cost GHG reduction potential as well as the public support for a more active GHG policy. (Author)

Due to the growing concern for global warming, the EU25 have implemented the European Union Greenhouse Gas Emission Trading Scheme (EU ETS). In the first trading period (2005-2007), part of the targeted GHG emission reductions presumably will have to result from a switch from coal fired electricity generation to gas fired electricity generation. It is possible to calculate the allowance cost necessary to switch a certain coal fired plant with a certain gas fired plant in the merit order. The allowance cost obtained is a so called switching point. When comparing historic European Union Allowance (EUA) prices (2005) with the corresponding historic switching points, the EUA prices were found high enough to cause a certain switch in the summer season. This finding leads to the use of switching points in establishing allowance cost profiles for several scenarios. A variable gas price profile is used in the simulation tool E-Simulate to simulate electricity generation and related GHG emissions in an eight zonal model representing Western Europe. Several GHG allowance cost profile scenarios are examined. For each scenario, electricity generation in the considered countries is clarified. The focus however lies on the GHG emission reduction potentials. These potentials are addressed for each scenario

This study estimates global time-series consumption-based GHG emissions by region from 1990 to 2005, including both CO 2 and non-CO 2 GHG emissions. Estimations are conducted for the whole economy and for two specific sectors: manufacturing and agriculture. Especially in the agricultural sector, it is important to include non-CO 2 GHG emissions because these are the major emissions present. In most of the regions examined, the improvements in GHG intensities achieved in the manufacturing sector are larger than those in the agricultural sector. Compared with developing regions, most developed regions have consistently larger per-capita consumption-based GHG emissions over the whole economy, as well as higher production-based emissions. In the manufacturing sector, differences calculated by subtracting production-based emissions from consumption-based GHG emissions are determined by the regional economic level while, in the agricultural sector, they are dependent on regional production structures that are determined by international trade competitiveness. In the manufacturing sector, these differences are consistently and increasingly positive for the U.S., EU15 and Japan but negative for developing regions. In the agricultural sector, the differences calculated for the major agricultural importers like Japan and the EU15 are consistently positive while those of exporters like the U.S., Australia and New Zealand are consistently negative. - Highlights: ► We evaluate global time-series production-based and consumption-based GHG emissions. ► We focus on both CO 2 and non-CO 2 GHG emissions, broken down by region and by sector. ► Including non-CO 2 GHG emissions is important in agricultural sector. ► In agriculture, differences in accountings are dependent on production structures. ► In manufacturing sector, differences in accountings are determined by economic level.

The challenges facing the Canadian government in implementing a green house gas (GHG) emissions trading program were discussed. The government of Canada is proposing to establish a program offering credit for early action on GHG reduction. However, the program is proving to be difficult to design because Canada's national implementation strategy for climate change has not yet been defined. The program is intended to reveal how emitters can invest in GHG reduction now, and use them against future regulations limiting emissions. The intention is to design the program on the principle that any company which decreases GHG emissions below its 'business-as-usual' level will receive a credit which can later be sold to another source which wants to offset its emissions. Nevertheless, the government is looking for real reductions in the sense that it is trying to bend the 'business-as-usual' forecast down towards the Kyoto targets, and is trying to ensure that the system is a rigorous one before any credits are issued

Worldwide electricity sector reforms open up electricity markets and increase trades. This has environmental consequences as exports and imports either increase or decrease local production and consequently greenhouse gas (GHG) emissions. This paper's objective is to illustrate the importance of electricity trade's impact on GHG emissions by providing an estimate of the net GHG emissions resulting from these trades. To achieve this objective, Quebec hourly electricity exchanges with adjacent jurisdictions were examined over the 2006-2008 period. In order to associate a specific GHG emission quantity to electricity trades, hourly marginal electricity production technologies were identified and validated using the Ontario hourly output per power plant and information released in the Quebec adjacent system operator reports. It is estimated that over three years, imports into Quebec were responsible for 7.7 Mt of GHG, while Quebec hydropower exports avoided 28.3 Mt of GHG emissions. Hence, the net result is 20.6 Mt of avoided emissions over 2006-2008, or about 7 Mt per year, which corresponds to more than 8% of the Quebec yearly GHG emissions. When GHG emissions from all life cycle stages (resource extraction to end-of-life) are accounted for, the net avoided GHG emissions increase by 35%, to 27.9 Mt. - Research highlights: → Environmental benefits of hydropower exports are considerable. → Detailed GHG assessment of such electricity trade is missing from the literature. → Net GHG emissions estimate resulting from such trade is provided. → GHG gains are significant in the Northeast American electricity market due to such electricity trade.

This PowerPoint presentation provided a brief overview of Alcan, an aluminium producer with operations in Quebec and in several other markets and countries. Alcan's strategy regarding climate change involves both short term and long term objectives and a public commitment to reducing the emissions of greenhouse gases (GHG). Alcan has implemented a company-wide GHG management program called TARGET, which involves measuring, monitoring and better management of emissions inventory. The TARGET program includes: measurement of data, quality assurance and reports; communications and public relations; improved processes; risk management systems; development of emissions trading systems; and support of functional groups. Alcan has also implemented voluntary GHG emissions reductions measures, encourages broad participation of GHG emissions reduction initiatives, and promotes economic growth and long term durability. figs

Highlights: • A simplified methodology for the balance and saving of GHG emissions is provided. • The GHG balance has a physical meaning and does not depend on the fossil reference. • The GHG saving depends on regulation of energy carriers. • The impact of Bio-CCS incorporation and multiproduction is analyzed. • The co-production of chemicals needs to be included in future regulation. - Abstract: In this study, a simplified methodology for the calculation of the balance of greenhouse gas (GHG) emissions and corresponding saving compared with the fossil reference is presented. The proposed methodology allows the estimation of the anthropogenic GHG emissions of thermochemical biorefineries (net emitted to the atmosphere). In the calculation of the GHG balance, all relevant factors have been identified and analyzed including multiproduction, emissions from biogenic carbon capture and storage (Bio-CCS), co-feeding of fossil fuels (secondary feedstock) and possible carbon storage in biomass-derived products (chemicals). Therefore, it is possible to calculate the balance of GHG emissions of a hypothetical thermochemical biorefinery considering different alternatives of land-use, biomass feedstock, co-feeding of fossil fuels, Bio-CCS incorporation and final use of the products. The comparison of the estimated GHG balance with the corresponding fossil reference for each product is of special relevance in the methodology since it is the parameter used in European regulation for the fulfillment of sustainability criteria in biomass-derived fuels and liquids. The proposed methodology is tested using a previously assessed set of different process concepts of thermochemical biorefineries (techno-economic analysis). The resulting GHG balance and saving are analyzed to identify uncertainties and provide recommendations for future regulation. In all process concepts, the GHG savings are above the minimum requirement of GHG emissions for 2018. In the case of incorporating

The objective of this report is to provide an early estimate of greenhouse gas (GHG) emissions in the EU-15 and EU-27 for the year 2011. The official submission of 2011 data to the United Nations Framework Convention on Climate Change (UNFCCC) will occur in 2013. In recent years, the EEA and its European Topic Centre on Air Pollution and Climate Change Mitigation have developed a methodology to estimate GHG emissions using a bottom up approach - based on data or estimates for individual countries, sectors and gases - to derive EU GHG estimates in the preceding year (t-1). For transparency, this report shows the country-level GHG estimates from which the EU estimates have been derived. The 2011 estimates are based on the latest activity data available at country level and assume no change in emission factors or methodologies as compared to the official 2012 submissions to UNFCCC (which relate to emissions in 2010). Some Member States estimate and publish their own early estimates of GHG emissions for the preceding year. Where such estimates exist they are clearly referenced in this report in order to ensure complete transparency regarding the different GHG estimates available. Member State early estimates were also used for quality assurance and quality control of the EEA's GHG early estimates for 2011. Finally, the EEA has also used the early estimates of 2011 GHG emissions produced by EEA member countries to assess progress towards the Kyoto targets in its annual trends and projections report (due to be published alongside the present report). In that report, the EEA's early estimates for 2011 were only used for countries that lack their own early estimates to track progress towards national and EU targets. (LN)

City and State governments are increasingly interested in mitigating greenhouse gas (GHG) emissions to improve sustainability within their jurisdictions. Estimation of urban GHG emissions remains an active research area with many sources of uncertainty. To support the effort of improving measurement of trace gas emissions in city environments, several federal agencies along with academic, research, and private entities have been working within a handful of domestic metropolitan areas to improve both (1) the assessment of GHG emissions accuracy using a variety of measurement technologies, and (2) the tools that can better assess GHG inventory data at urban mitigation scales based upon these measurements. The National Institute of Standards and Technology (NIST) activities have focused on three areas, or testbeds: Indianapolis (INFLUX experiment), Los Angeles (the LA Megacities project), and the Northeastern Corridor areas encompassing Washington and Baltimore (the NEC/BW GHG Measurements project). These cities represent diverse meteorological, terrain, demographic, and emissions characteristics having a broad range of complexities. To date this research has involved multiple measurement systems and integrated observing approaches, all aimed at advancing development of a robust, science-base upon which higher accuracy quantification approaches can rest. Progress toward such scientifically robust, widely-accepted emissions quantification methods will rely upon continuous performance assessment. Such assessment is challenged by the complexities of cities themselves (e.g., population, urban form) along with the many variables impacting a city's technological ability to estimate its GHG emissions (e.g., meteorology, density of observations). We present the different NIST testbeds and a proposal to initiate conceptual development of a reference framework supporting the comparison of multi-city GHG emissions estimates. Such a reference framework has potential to provide

Highlights: • We modeled life cycle energy and greenhouse gas (GHG) emissions from diverse powertrain vehicles. • Lightweight versions of the vehicle models were compared against baseline models. • Maximum energy and GHG emissions occur with aluminum vs. advanced high strength steel. • Design harmonization method shows 0.2–0.3 kg of support required per 1 kg powertrain mass increase. - Abstract: This work assesses the potential of electrified vehicles and mass reduction to reduce life cycle energy and greenhouse gas (GHG) emissions. Life cycle assessment (LCA) is used to account for processes upstream and downstream of the vehicle operation, thereby incorporating regional variation of energy and GHG emissions due to electricity production and distinct energy and GHG emissions due to conventional and lightweight materials. Design harmonization methods developed in previous work are applied to create baseline and lightweight vehicle models of an internal combustion vehicle (ICV), hybrid electric vehicle (HEV) and plug-in hybrid electric vehicle (PHEV). Thus, each vehicle is designed to be functionally equivalent and incorporate the structural support required for heavier powertrains. Lightweight vehicles are designed using body-in-white (BIW) mass reduction scenarios with aluminum and advanced/high strength steel (A/HSS). For the mass reduction scenarios considered in this work, results indicate that the greatest life cycle energy and GHG emissions reductions occur when steel is replaced by aluminum. However, since A/HSS requires less energy to produce as compared to aluminum, the energy and GHG reductions per unit mass removed is greatest for A/HSS. Results of the design harmonization modeling method show that 0.2–0.3 kg of structural support is required per unit increase in powertrain mass, thus extending previous methods

Reassessing the Links between GHG Emissions, Economic Growth, and the UNFCCC: A Difference-in-Differences Approach

Full Text Available International climate agreements such as the Kyoto Protocol of 1997 and, more recently, the Paris Climate Agreement are fragile because, at a national level, political constituencies’ value systems may conflict with the goal of reducing greenhouse gas (GHG emissions to sustainable levels. Proponents cite climate change as the most pressing challenge of our time, contending that international cooperation will play an essential role in addressing this challenge. Political opponents argue that the disproportionate requirements on developed nations to shoulder the financial burden will inhibit their economic growth. We find empirical evidence that both arguments are likely to be correct. We use standard regression techniques to analyze a multi-country dataset of GHG emissions, GDP per capita growth, and other factors. We estimate that after the Kyoto Protocol (KP entered into force ‘Annex I’ countries reduced GHG emissions on average by roughly 1 million metric tons of CO2 equivalent (MTCO2e, relative to non-Annex I countries. However, our estimates reveal that these countries also experienced an average reduction in GDP per capita growth rates of around 1–2 percentage points relative to non-Annex I countries.

Strengthening community participation is needed to find solutions to encourage community more participate in reducing Green House Gas (GHG) from forest and peatland fire. This research aimed to identify stakeholders that have the role in forest and peatland fire control and to formulate strengthening model of community participation through community-based early warning fire. Stakeholder mapping and action research were used to determine stakeholders that had potential influence and interest and to formulate strengthening model of community participation in reducing GHG from forest and peatland fire. There was found that position of key players in the mapping of stakeholders came from the government institution. The existence of community-based fire control group can strengthen government institution through collaborating with stakeholders having strong interest and influence. Moreover, it was found several local knowledge in Kapuas District about how communities predict drought that have potential value for developing the community-based early warning fire system. Formulated institutional model in this research also can be further developed as a model institution in the preservation of natural resources based on local knowledge. In conclusion, local knowledge and community-based fire groups can be integrated within strengthening model of community participation in reducing GHG from forest and peatland fire.

Technology Roadmap: Energy and GHG reductions in the chemical industry via catalytic processes

2013-06-01

The chemical industry is a large energy user; but chemical products and technologies also are used in a wide array of energy saving and/or renewable energy applications so the industry has also an energy saving role. The chemical and petrochemical sector is by far the largest industrial energy user, accounting for roughly 10% of total worldwide final energy demand and 7% of global GHG emissions. The International Council of Chemical Associations (ICCA) has partnered with the IEA and DECHEMA (Society for Chemical Engineering and Biotechnology) to describe the path toward further improvements in energy efficiency and GHG reductions in the chemical sector. The roadmap looks at measures needed from the chemical industry, policymakers, investors and academia to press on with catalysis technology and unleash its potential around the globe. The report uncovers findings and best practice opportunities that illustrate how continuous improvements and breakthrough technology options can cut energy use and bring down greenhouse gas (GHG) emission rates. Around 90% of chemical processes involve the use of catalysts – such as added substances that increase the rate of reaction without being consumed by it – and related processes to enhance production efficiency and reduce energy use, thereby curtailing GHG emission levels. This work shows an energy savings potential approaching 13 exajoules (EJ) by 2050 – equivalent to the current annual primary energy use of Germany.

Estimating GHG emissions of marine ports-the case of Barcelona

Villalba, Gara; Gemechu, Eskinder Demisse

2011-01-01

In recent years, GHG inventories of cities have expanded to include extra-boundary activities that form part of the city's urban metabolism and economy. This paper centers on estimating the emissions due to seaports, in such a way that they can be included as part of the city's inventory or be used by the port itself to monitor their policy and technology improvements for mitigating climate change. We propose the indicators GHG emissions per ton of cargo handled or per passenger and emissions per value of cargo handled as practical measures for policy making and emission prevention measures to be monitored over time. Adapting existing methodologies to the Port of Barcelona, we calculated a total of 331,390 tons of GHG emissions (CO 2 equivalents) for the year of 2008, half of which were attributed to vessel movement (sea-based emissions) and the other half to port, land related activities (land-based emissions). The highest polluters were auto carriers with 6 kg of GHG emissions per ton of cargo handled. Knowing the highest emitters, the port can take action to improve the ship's activities within the port limits, such as maneuvering and hotelling. With these results, the port and the city can also find ways to reduce the land-based emissions. - Research highlights: → Adapting existing methodologies to the Port of Barcelona (PoB), we calculated a total of 331,390 tons of GHG emissions for the year of 2008, half of which were attributed to vessel movement (sea-based emissions) and the other half to port, land related activities (land-based emissions) → Emissions per ton of cargo handled is proposed as an indicator to pin point high polluting vessels-a measure independent of the city the port belongs to. For 2008, the highest polluters were auto carriers with 6 kg of GHG emissions per ton of cargo handled. → An additional measure of emissions per value of cargo handled is proposed to complement the emissions per weight indicator. For 2008, the volume of cargo

Highlights: • CHP attributable reductions, not viable by electric generation alone, are defined. • Simplified operating strategy heuristics are optimal under specific circumstances. • Phosphoric acid fuel cells yield the largest reductions except in the extremes. • Changes in baseline emissions affect the optimal system capacity and operating hours. - Abstract: This work aims to elucidate notions concerning the ideal operation and greenhouse gas (GHG) emissions benefits of combined heat and power (CHP) systems by investigating how various metrics change as a function of the GHG emissions from the underlying electricity source, building use type and climate. Additionally, a new term entitled “CHP Attributable” reductions is introduced to quantify the benefits from the simultaneous use of thermal and electric energy, removing benefits achieved solely from fuel switching and generating electricity more efficiently. The GHG emission benefits from implementing internal combustion engine, microturbines, and phosphoric acid (PA) fuel cell based CHP systems were evaluated through an optimization approach considering energy demands of prototypical hospital, office, and residential buildings in varied climates. To explore the effect of electric GHG emissions rates, the ideal operation of the CHP systems was evaluated under three scenarios: “High” GHG emissions rates, “Low” GHG emissions rates, and “Current” GHG emissions rate for a specific location. The analysis finds that PA fuel cells achieve the highest GHG emission reductions in most cases considered, though there are exceptions. Common heuristics, such as electric load following and thermal load following, are the optimal operating strategy under specific conditions. The optimal CHP capacity and operating hours both vary as a function of building type, climate and GHG emissions rates from grid electricity. GHG emissions reductions can be as high as 49% considering a PA fuel cell for a

Materials related to IEA Greenhouse Gas Rand D Program (IEA/GHG) were analyzed. The Sleipner carbon dioxide underground storage workshop is acting to narrow themes for understanding the technologies, observation methods, and research activities. The IEA/GHG has verified the known facts about ocean storage of carbon dioxide, and discussed the important development targets. Researches were made on improving methane recovery efficiency and the possibility of sealing carbon dioxide by injecting carbon dioxide in order to improve recovery of carbon bed methane. The IEA/GHG has developed a methodology for complete fuel cycles of LNG, and evaluated cost and benefit of reducing greenhouse effect gas emission. A process combining electric power generation, carbon dioxide absorption and hot heat energy utilization can reduce emission of carbon dioxide into atmosphere at relatively low cost and low energy loss. The paper also describes reduction of greenhouse effect gas emitted from cement factories, petroleum refining and petro-chemical industries, and offshore petroleum and gas facilities. It also describes influence of forestry on carbon absorption and timber markets. Case studies have discussed effects of modifying power generation plants. (NEDO)

Plug-in hybrid vehicle GHG impacts in California: Integrating consumer-informed recharge profiles with an electricity-dispatch model

2011-01-01

This paper explores how Plug-in Hybrid Vehicles (PHEVs) may reduce source-to-wheel Greenhouse Gas (GHG) emissions from passenger vehicles. The two primary advances are the incorporation of (1) explicit measures of consumer interest in and potential use of different types of PHEVs and (2) a model of the California electricity grid capable of differentiating hourly and seasonal GHG emissions by generation source. We construct PHEV emissions scenarios to address inherent relationships between vehicle design, driving and recharging behaviors, seasonal and time-of-day variation in GHG-intensity of electricity, and total GHG emissions. A sample of 877 California new vehicle buyers provide data on driving, time of day recharge access, and PHEV design interests. The elicited data differ substantially from the assumptions used in previous analyses. We construct electricity demand profiles scaled to one million PHEVs and input them into an hourly California electricity supply model to simulate GHG emissions. Compared to conventional vehicles, consumer-designed PHEVs cut marginal (incremental) GHG emissions by more than one-third in current California energy scenarios and by one-quarter in future energy scenarios-reductions similar to those simulated for all-electric PHEV designs. Across the emissions scenarios, long-term GHG reductions depends on reducing the carbon intensity of the grid. - Research highlights: → We estimate California Plug-in Hybrid Vehicle (PHEV) GHGs using consumer data and an electricity supply model. → Consumer-designed (mostly 'blended') PHEVs can reduce GHG emissions compared to conventional vehicles. → These PHEVs can also reduce GHG emissions relative to 'all-electric' PHEV designs. → 'All-electric' designs may further reduce GHG emissions as electricity carbon intensity falls. → Ranking of GHG savings from off-peak versus daytime charging scenarios depends on electricity carbon intensity.

This paper sums up the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas (GHG) emissions and energy use to cities, and a re-emergence of studies focusing on the direct and indirect urban material and resource flows. The availability of reliable data and standard protocols is greater in the GHG accounting field and continues to grow rapidly

Decoupling urban transport from GHG emissions in Indian cities-A critical review and perspectives

2011-01-01

How to sustain rapid economic and urban growth with minimised detriment to environment is a key challenge for sustainable development and climate change mitigation in developing countries, which face constraints of technical and financial resources scarcity as well as dearth of infrastructure governance capacity. This paper attempts to address this question by investigating the driving forces of transport demand and relevant policy measures that facilitate mitigating GHG emissions in the urban transport sector in Indian cities based on a critical review of the literature. Our overview of existing literature and international experiences suggests that it is critical to improve urban governance in transport infrastructure quality and develop efficient public transport, coupled with integrated land use/transport planning as well as economic instruments. This will allow Indian cities to embark on a sustainable growth pathway by decoupling transport services demand of GHG emissions in the longer term. Appropriate policy instruments need to be selected to reconcile the imperatives of economic and urban growth, aspiration to higher quality of life, improvements in social welfare, urban transport-related energy consumption and GHG emissions mitigation target in Indian cities. - Highlights: → Investigating the relevant policies that facilitate mitigating GHG emissions in urban transport in Indian cities. → Determining the factors of increase in energy demand and carbon emissions in transport. → Improving urban governance in transport infrastructure with integrated transport planning. → Designing and implementing the policy and economic instruments for low-carbon urban transport in India.

Biofuels should be produced more sustainable since the inception of the Renewable Energy Directive (EU-RED, 2009128/EG) in 2009. In comparison to fossil fuels biofuels have to achieve now a GHG reduction potential of 35 % (50 % from 2018). In a project at the State Research Center of Agriculture and Fisheries Mecklenburg- Vorpommern the current practical values of GHG emissions during the cultivation of rapeseed and wheat have been calculated. Bases of the calculation are operating agriculture data (harvesting 2011 until2015). The results show that the current GHG reduction potential can only be maintained at 26% of the studied rapeseed harvest quantity or at 75 %of the wheat harvest (own calculation). The default values of the EU-RED and the NUTS2 values cannot be achieved with the current agricultural production. Some calculating and agronomic optimization options for GHG reduction are available and must be implemented (for example: incorporating the oil content and the type of nitrogen fertilizer and reduced nitrogen fertilizer level). The aim is to keep the 50% GHG reduction potential of the EU-RED until 2018 to have a sure sustainable rapeseed and wheat cultivation for biofuel production.

Highlights: • Current building assessment does not account for variability in the electric grid. • A new method incorporates hourly grid variability into building assessment. • The method is complementary with peak-shaving policies. • The assessment method can affect building design decisions. - Abstract: Current building energy and GHG emissions assessments do not account for the variable performance of the electric grid. Incorporating hourly grid variability into building assessment methods can help to better prioritize energy efficiency measures that result in the largest environmental benefits. This article proposes a method to incorporate GHG emissions intensity changes due to grid variability into building environmental assessment. The proposed method encourages building systems that reduce electricity use during peak periods while accounting for differences in grid GHG emissions intensity (i.e., peak shaving is more strongly encouraged in grids that have GHG intense peak generation). A set of energy saving building technologies are evaluated in a set of building variants (office, residential) and grid types (hydro/nuclear dominated, coal/gas dominated) to demonstrate the proposed method. Differences between total GHG emissions calculated with the new method compared with the standard (which assumes a constant GHG emissions intensity throughout the year) are in the 5–15% range when the contribution of electricity to total GHG emissions is more significant. The influence of the method on the assessment of the relative performance of some energy efficiency measures is much higher. For example, the estimated GHG emissions savings with heat pumps and photovoltaics can change by −40% and +20%, respectively, using the new assessment method instead of the standard. These differences in GHG emissions estimates can influence building design decisions. The new method could be implemented easily, and would lead to better decision making and more accurate

Highlights: • Novel framework compares GHG of plugins vs. hybrids for any vehicle type/performance. • Fleet GHG can be compared without forecasting market penetrations of vehicle sizes. • GHG/km for pure electrics must account for limited range using novel, modified Utility Factor. • Applied to the US, this points to smaller GHG reduction at fleet level than traditional fleet analyses. - Abstract: Plugin and hybrid vehicles have been shown to offer possible reductions in greenhouse gas (GHG) emissions, depending on grid-carbon-intensity, range and thus life-cycle battery emissions and vehicle weight, and on trip patterns. We present a framework that enables GHG comparisons (well-to-wheel plus storage manufacturing) for three drivetrains (pure-electric, gasoline-hybrid, and plugin-hybrid), both for individual vehicles and for fleets. The framework captures effects of grid- versus vehicle-based electricity generation, grid transmission and charging losses, and manufacturing and carrying batteries. In contrast to previous work, GHG comparisons can be obtained for heterogeneous fleets of varying vehicle sizes (cars, vans, buses, trucks) and performances, without requiring forecasting of such vehicle specs and their respective market penetrations. Further, we show how a novel adaptation of the Utility Factor concept from plug-in-hybrids to mixed fleets of battery-only and gasoline-hybrids is crucial to quantifying battery-only-vehicles’ impact on fleet-wide GHG. To account for regional variations and possible future technology improvements, we show scenarios over a wide spectrum of grid-carbon-intensities (50–1200 g CO 2 e/kW h at wall), vehicle range (∼5–500 km), battery energy densities, and battery life-cycle GHG. Model uncertainties are quantified via sensitivity tests. Applying the framework to trip patterns of US passenger transportation, we find that owing to the interplay of GHG/km, battery size, all-electric range, and trip patterns, GHG

GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) was conceived to build upon ongoing USDA Agricultural Research Service (ARS) research to improve soil productivity, while addressing the challenges and opportunities of interest in C sequestration from a climate change perspective. The vision for GRACEnet was and remains: Knowledge and information used to implement scientifically based agricultural management practices from the field to national policy scales on C sequestration, greenhouse gas (GHG) emissions, and environmental benefits. The national focus of GRACEnet uses a standardized approach by ARS laboratories and university and land manager (e.g. farmer and rancher) cooperators to assess C sequestration and GHG emission from different crop and grassland systems. Since 2002, GRACEnet has significantly expanded GHG mitigation science and delivered usable information to agricultural research and policy organizations. Recent developments suggest GRACEnet will have international impact by contributing leadership and technical guidance for the Global Research Alliance on Agricultural Greenhouse Gases.

The Energy Independence and Security Act (EISA) of 2007 established new renewable fuel categories and eligibility requirements (EPA 2010). A significant aspect of the National Renewable Fuel Standard 2 (RFS2) program is the requirement that the life cycle greenhouse gas (GHG) emissions of a qualifying renewable fuel be less than the life cycle GHG emissions of the 2005 baseline average gasoline or diesel fuel that it replaces. Four levels of reduction are required for the four renewable fuel standards. Table 1 lists these life cycle performance improvement thresholds. Table 1. Life Cycle GHG Thresholds Specified in EISA Fuel Type Percent Reduction from 2005 Baseline Renewable fuel 20% Advanced biofuel 50% Biomass-based diesel 50% Cellulosic biofuel 60% Notably, there is a specialized subset of advanced biofuels that are the cellulosic biofuels. The cellulosic biofuels are incentivized by the Cellulosic Biofuel Producer Tax Credit (26 USC 40) to stimulate market adoption of these fuels. EISA defines a cellulosic biofuel as follows (42 USC 7545(o)(1)(E)): The term “cellulosic biofuel” means renewable fuel derived from any cellulose, hemicellulose, or lignin that is derived from renewable biomass and that has lifecycle greenhouse gas emissions, as determined by the Administrator, that are at least 60 percent less than the baseline lifecycle greenhouse gas emissions. As indicated, the Environmental Protection Agency (EPA) has sole responsibility for conducting the life cycle analysis (LCA) and making the final determination of whether a given fuel qualifies under these biofuel definitions. However, there appears to be a need within the LCA community to discuss and eventually reach consensus on discerning a 50–59 % GHG reduction from a ≥ 60% GHG reduction for policy, market, and technology development. The level of specificity and agreement will require additional development of capabilities and time for the sustainability and analysis community, as illustrated

Cradle to grave GHG emissions analysis of shale gas hydraulic fracking in Western Australia

Full Text Available Western Australia has globally significant onshore gas resources, with over 280 trillion cubic feet of economically recoverable gas located in five shale basins. The Western Australian Government and gas industry have promoted the development of these resources as a “clean energy source” that would “help to reduce global carbon emissions” and provide a “transition fuel” to a low carbon economy. This research examines those claims by reviewing existing literature and published data to estimate the life cycle greenhouse gas (GHG pollution that would result from the development of Western Australia’s onshore gas basins using hydraulic fracking. Estimates of carbon pollution from each stage in gas development, processing, transport and end-use are considered in order to establish total life-cycle emissions in tonnes of carbon-dioxide equivalent (CO2e. The emissions estimates draw from published research on emissions from shale gas development in other jurisdictions as well as industry or government reported emissions from current technology for gas processing and end-use as applicable. The current policy and regulatory environment for carbon pollution and likely resulting GHG mitigation measures has also been considered, as well as the potential for the gas to displace or substitute for other energy sources. In areas where there is uncertainty, conservative emissions estimates have been used. Modelling of GHG emissions has been undertaken for two comparison resource development and utilisation scenarios; Australian domestic and 100% export i.e. no domestic use. Each scenario corresponds to a different proportionate allocation of emissions accounted for domestic emissions in Australia and emissions accounted for in other jurisdictions. Emissions estimates for the two scenarios are 245–502 MTCO2e/year respectively over a resource development timeframe of 20 years. This is roughly the same as Australia’s total GHG emissions in 2014

In June 1992 the representatives of 176 countries including Ukraine met in Rio de Janeiro at the UN Conference to coordinate its efforts in protecting and guarding the environment. Signature of the UN Framework Convention on Climate Change by around 150 countries indicates that climate change is potentially a major threat to the world`s environment and economic development. The project {open_quotes}Country Study on Climate Change in Ukraine{close_quotes} coordinated by the Agency for Rational Energy Use and Ecology (ARENIA-ECO) and supported by the US Country Studies Program Support for Climate Change Studies. The aim of the project is to make the information related to climate change in Ukraine available for the world community by using the potential of Ukrainian research institutes for further concerted actions to solve the problem of climate change on the global scale. The project consists of four elements: (1) the development of the GHG Inventory in Ukraine; (2) assessments of ecosystems-vulnerability to climate change and adaptation options; and (3) mitigation options analysis; (4) public education and outreach activities. This paper contains the main results of the third element for the energy and non-energy sectors. Main tasks of the third element were: (1) to select, test and describe or develop the methodology for mitigation options assessment; (2) to analyze the main sources of GHG emissions in Ukraine; (3) to give the macro economic analysis of Ukrainian development and the development of main economical sectors industry, energy, transport, residential, forestry and agriculture; (4) to forecast GHG emissions for different scenarios of the economic development; and (5) to analyze the main measures to mitigate climate change.

In an effort to obtain the most accurate climate change impact assessment, greenhouse gas (GHG) accounting is evolving to include life-cycle thinking. This study (1) identifies similarities and key differences between GHG accounting and life-cycle assessment (LCA), (2) compares them on a consistent basis through a case study on a waste management business unit. First, GHG accounting is performed. According to the GHG Protocol, annual emissions are categorized into three scopes: direct GHG emissions (scope 1), indirect emissions related to electricity, heat and steam production (scope 2) and other indirect emissions (scope 3). The LCA is then structured into a comparable framework: each LCA process is disaggregated into these three scopes, the annual operating activities are assessed, and the environmental impacts are determined using the IMPACT2002+ method. By comparing these two approaches it is concluded that both LCA and GHG accounting provide similar climate change impact results as the same major GHG contributors are determined for scope 1 emissions. The emissions from scope 2 appear negligible whereas emissions from scope 3 cannot be neglected since they contribute to around 10% of the climate change impact of the waste management business unit. This statement is strengthened by the fact that scope 3 generates 75% of the resource use damage and 30% of the ecosystem quality damage categories. The study also shows that LCA can help in setting up the framework for a annual GHG accounting by determining the major climate change contributors.

In Europe, the highly developed livestock industry places a high burden on resource use and environmental quality. This paper examines pig meat production in North-West Europe as a base case and runs different scenarios to investigate how improvements in terms of energy and greenhouse gas (GHG) savings can be feasibly achieved. As shown in the results of the analysis, pig farming in the EU has a high potential to reduce fossil energy use and GHG emissions by taking improvement measures in three aspects: (i) feed use; (ii) manure management; and (iii) manure utilization. In particular, a combination of improvements in all mentioned aspects offers the highest savings potential of up to 61% fossil energy and 49% GHG emissions. In weighing these three aspects, manure utilization for energy production is found to be the most important factor in reducing fossil energy use and GHG emissions. However, when GHG implications of land use change and land opportunity cost associated with the production of feed crops (e.g. soy meal, cereals) are considered, reducing feed use becomes the main factor in improving GHG performance of EU pork.

2015-12-11

This study estimates the range of fuel and emissions impact of an automated-vehicle (AV) based transit system that services campus-based developments, termed an automated mobility district (AMD). The study develops a framework to quantify the fuel consumption and greenhouse gas (GHG) emission impacts of a transit system comprised of AVs, taking into consideration average vehicle fleet composition, fuel consumption/GHG emission of vehicles within specific speed bins, and the average occupancy of passenger vehicles and transit vehicles. The framework is exercised using a previous mobility analysis of a personal rapid transit (PRT) system, a system which shares many attributes with envisioned AV-based transit systems. Total fuel consumption and GHG emissions with and without an AMD are estimated, providing a range of potential system impacts on sustainability. The results of a previous case study based of a proposed implementation of PRT on the Kansas State University (KSU) campus in Manhattan, Kansas, serves as the basis to estimate personal miles traveled supplanted by an AMD at varying levels of service. The results show that an AMD has the potential to reduce total system fuel consumption and GHG emissions, but the amount is largely dependent on operating and ridership assumptions. The study points to the need to better understand ride-sharing scenarios and calls for future research on sustainability benefits of an AMD system at both vehicle and system levels.

2017-03-01

Full Text Available Climate change and greenhouse gas (GHG emissions have attracted much attention for their impacts upon the global environment. Initiating of new legislation and regulations for control of GHG emissions from the industrial sectors has been applied to address this problem. The transportation industries, which include operation of road pavement and pavement construction equipment, are the highest GHG-emitting sectors. This study presents a novel quantification model of GHG emissions of pavement construction using process-based analysis. The model is composed of five modules that evaluate GHG emissions. These are: material production and acquisition, (2 material transport to a project site, (3 heavy equipment use, (4 on-site machinery use, and, (5 on-site electricity use. The model was applied to a hypothetical pavement project to compare the environmental impacts of flexible and rigid pavement types during construction. The resulting model can be used for evaluation of environmental impacts, as well as for designing and planning highway pavement construction.

Highlights: • GHG emissions from primary aluminum production in China were accounted. • The impact of regional disparity of power generation was considered for this study. • GHG emissions factor of China’s primary aluminum production was 16.5 t CO_2e/t Al ingot in 2013. • Total GHG emissions from China’s primary aluminum production were 421 mt CO_2e in 2013. - Abstract: China is the world-leading primary aluminum production country, which contributed to over half of global production in 2014. Primary aluminum production is power-intensive, for which power generation has substantial impact on overall Greenhouse Gas (GHG) emissions. In this study, we explore the impact of regional disparity of China’s power generation system on GHG emissions for the sector of primary aluminum production. Our analysis reveals that the national GHG emissions factor (GEF) of China’s primary aluminum production was 16.5 t CO_2e/t Al ingot in 2013, with province-level GEFs ranging from 8.2 to 21.7 t CO_2e/t Al ingot. There is a high coincidence of provinces with high aluminum productions and high GEFs. Total GHG emissions from China’s primary aluminum production were 421 mt CO_2e in 2013, approximately accounting for 4% of China’s total GHG emissions. Under the 2020 scenario, GEF shows a 13.2% reduction compared to the 2013 level, but total GHG emissions will increase to 551 mt CO_2e. Based on our analysis, we recommend that the government should further promote energy efficiency improvement, facilitate aluminum industry redistribution with low-carbon consideration, promote secondary aluminum production, and improve aluminum industry data reporting and disclosure.

The allocation of emissions embodied in international trade is crucial to evaluate the real impact that each country has on climate change and its responsibility in greenhouse gas (GHG) emissions. In this paper, we develop a new theoretical framework recently proposed by Caro et al. (2014) that computes the carbon emissions embodied in international trade according to a consumption-based accounting. The method uses the value of the goods traded internationally and the respective carbon intensity as a coefficient of national efficiency. To provide an example of application of the proposed methodology and assess its difference with respect to the current producer-based GHG accounting, we analyze a trilateral trade system composed by three countries (Sweden, Italy, and Poland) with large differences in terms of carbon intensity (low, medium, and high carbon intensity, respectively). From the analysis of the data during the period 2000–2008, it emerges that the proposed consumption-based accounting would imply an increase of Italian and Swedish emission responsibility by 1.4 and 11.8%, respectively, with respect to the conventional GHG accounting, and a decrease of the Polish responsibility by 2.81%. To assess the possible consequences deriving from the application of this new methodology, we also consider the effects of a shift of the Italian imports from Poland to Sweden of Machinery and Transport Equipments, a crucial sector in the trade relations among the three countries, which accounts for about 45% of total exports from Poland and Sweden to Italy. Finally, we discuss some policy implications deriving from the application of the consumption-based accounting, devoting particular attention to the results emerging from its hypothetical adoption in the EU-27. The analysis performed in the paper suggests that the adoption of a consumption-based accounting could be an important tool in the climate change challenge to reduce global emissions.

2016-01-01

Highlights: • Energy use and GHG emissions of different neighborhood designs are investigated. • Improving buildings energy performance reduces energy use and GHG emissions by 75%. • Density as isolated factor has limited effect on transport on per capita basis. • Distance to central business district impacts transport GHG emission significantly. - Abstract: This paper presents an innovative and holistic approach to the analysis of the impact of selected design parameters of a new solar community on its environmental performance, in terms of energy efficiency and carbon footprint (green-house gas (GHG) emissions). The design parameters include energy performance level of buildings, density, type of the neighborhood (mixed-use vs residential), location of the commercial center relative to residential areas and the design of the streets. Energy performance is measured as the balance between overall energy consumption for building operations (assuming an all-electric neighborhood) and electricity generation potential through integration of PV panels on available roof surfaces. Greenhouse gas emissions are those associated with building operations and transport. Results of simulations carried out on prototype neighborhoods located in the vicinity of Calgary, Alberta, Canada indicate that, while adopting high-energy efficiency measures can reduce the buildings’ impact by up to 75% in terms of energy consumption and GHG emissions, transport still has a large environmental impact. The parameters of highest impact on transport and its associated GHG emissions are the design of the neighborhood and the distance to the business center. Density, as isolated parameter, has a modest effect on the selected mode of transportation, in terms of using private or public transportation. While this study relates to a specific location and a range of design assumptions, the methodology employed can serve as a template for evaluating design alternatives of new sustainable

Short-Term Power Plant GHG Emissions Forecasting Model

International Nuclear Information System (INIS)

Vidovic, D.

2016-01-01

In 2010, the share of greenhouse gas (GHG) emissions from power generation in the total emissions at the global level was about 25 percent. From January 1st, 2013 Croatian facilities have been involved in the European Union Emissions Trading System (EU ETS). The share of the ETS sector in total GHG emissions in Croatia in 2012 was about 30 percent, where power plants and heat generation facilities contributed to almost 50 percent. Since 2013 power plants are obliged to purchase all emission allowances. The paper describes the short-term climate forecasting model of greenhouse gas emissions from power plants while covering the daily load diagram of the system. Forecasting is done on an hourly domain typically for one day, it is possible and more days ahead. Forecasting GHG emissions in this way would enable power plant operators to purchase additional or sell surplus allowances on the market at the time. Example that describes the operation of the above mentioned forecasting model is given at the end of the paper.(author).

India is one of the world's largest greenhouse gas (GHG) emitter, accounting for about 5% of global emissions with further increases expected in the future. The Government of India aims to reduce emission intensities by 20-25% by 2020 compared with the 2005 level. In a recent departure from past practice the reconvened Council on Climate Change stated that climate change in agriculture would include a component that would focus on reducing emissions in agriculture, particularly methane and nitrous oxide emissions. To develop recommendations for mitigation in agriculture in India, a baseline study is presented to analyse the GHG emissions from agriculture for current management (Directorate of Economics and Statistics of the government of India). This analysis is done for the two states Bihar and Haryana, which differ in their management and practises based on different climate and policies. This first analysis shows were the highest GHG emissions in agriculture is produced and were the highest mitigation potential might be. The GHG emissions and mitigation potential are calculated using the CCAFS Mitigation Option Tool (CCAFS-MOT) (https://ccafs.cgiar.org/mitigation-option-tool-agriculture#.VpTnWL826d4) with modifications for the special modelling. In a second step, stakeholder meetings provided a wide range of possible and definite scenarios (management, policy, technology, costs, etc.) for the future to mitigate emissions in agriculture as well as how to increase productivity. These information were used to create scenarios to give estimates for the mitigation potential in agriculture for India in 2020.

Highlights: • Life cycle GHG emissions of rice straw bio-DME production in Thailand are assessed. • Bio-DME replaces diesel in engines and supplements LPG for household application. • Rice straw bio-DME in both cases of substitution helps reduce GHG emissions. - Abstract: Thailand is one of the leading countries in rice production and export; an abundance of rice straw, therefore, is left in the field nowadays and is commonly burnt to facilitate quick planting of the next crop. The study assesses the life cycle greenhouse gas (GHG) emissions of using rice straw for bio-DME production in Thailand. The analysis is divided into two scenarios of rice straw bio-DME utilization i.e. used as automotive fuel for diesel engines and used as LPG supplement for household application. The results reveal that that utilization of rice straw for bio-DME in the two scenarios could help reduce GHG emissions by around 14–70% and 2–66%, respectively as compared to the diesel fuel and LPG substituted. In case rice straw is considered as a by-product of rice cultivation, the cultivation of rice straw will be the major source of GHG emission contributing around 50% of the total GHG emissions of rice straw bio-DME production. Several factors that can affect the GHG performance of rice straw bio-DME production are discussed along with measures to enhance GHG performance of rice straw bio-DME production and utilization

The estimation of greenhouse gas (GHG) emissions associated with international trade and final consumption gives a more complete and balanced picture of the responsibilities of various countries for the emissions that cause the climate change. The aim of this study was to look at the impact of the coverage of the GHGs and their sources and assumptions regarding the emissions of imports on the results of GHG emissions associated with international trade and final consumption of Finland. In addition to a single year study, a trend covering years 1990-2003 was produced for Finland to study the development of the GHG emissions associated with domestic consumption and the reasons behind the development. According to our results Finland was in 1999 a net exporter of CO 2 from fossil fuel combustion, CO 2 from all sources and GHGs of 4(4.2), 5 or 7 Gkg, respectively. The impact of different assumptions concerning the emissions embodied in imports in the case of Finland was tested by using the domestic emission intensities and the ratios of embodied emissions in imports in relation to domestic products by utilizing the data from the study by (OECD, 2003b. Carbon Dioxide Emissions Embodied in International Trade of Goods, STI Working Paper 2003/15, OECD, Paris). In the case of Finland, the differences of results calculated with these two methods remained rather small. The total emissions embodied in the imports changed from 33.8 to 34.4 Gkg and consequently the net export of CO 2 from fossil fuel combustion changed from 4.2 to 3.6 Gkg. The results for 1990-2003 show that the GHG emissions embodied in the exports have exceeded the GHG emissions embodied in the imports from early 1990s. The reason for the increasingly positive GHG trade balance in the case of Finland has been the change in the magnitude of trade rather than the changes in its structure. The results show also that the impact of international transport on the emission intensity of imports is significant and

Highlights: ► We analyzed the life cycle energy intensity and GHG emissions of about 40 pathways of alternative vehicle fuels in China. ► Coal-based liquid fuel has higher life cycle energy intensities and first generation technology bio-fuel has relatively lower intensity. ► By 2020 electricity will have significantly lower GHG intensity and second generation technology bio-fuel will have near zero intensities. -- Abstract: Fossil energy consumption (FEC) and greenhouse gas (GHG) emission intensities of major alternative vehicle fuels (AVFs) in China are calculated and compared with conventional fuels by means of full life-cycle analysis. Currently most of the AVFs have not relatively obvious GHG emission reduction when compared to the gasoline pathway: (1) coal-based AVF has higher intensities in terms of both the FEC and GHG emissions; (2) electricity from the average Chinese grid has the GHG emission intensity similar to that of gasoline pathway although relatively lower FEC intensity; and (3) first generation technology bio-fuel has relatively lower GHG emission intensity and substantially lower FEC intensity. It is forecasted that by 2020 when still comparing to the gasoline pathway: (1) coal-based AVF will still have FEC and GHG emission intensities that are 1.5–1.8 and 1.8–2.5 time those of gasoline pathway, and the application of carbon capture and storage technology can reduce the GHG emission intensity of coal-based AVF; (2) electricity will have significantly lower GHG intensity; and (3) second generation technology bio-fuel will have near zero FEC and GHG intensities.

The distribution of the mitigation burden across countries is a key issue regarding the post-2012 global climate policies. This article explores the economic implications of alternative allocation rules, an assessment made in the run-up to the COP15 in Copenhagen (December 2009). We analyse the comparability of the allocations across countries based on four single indicators: GDP per capita, GHG emissions per GDP, GHG emission trends in the recent past, and population growth. The multi-sectoral computable general equilibrium model of the global economy, GEM-E3, is used for that purpose. Further, the article also compares a perfect carbon market without transaction costs with the case of a gradually developing carbon market, i.e. a carbon market with (gradually diminishing) transaction costs. - Highlights: ► Burden sharing of global mitigation efforts should consider equity and efficiency. ► The comparability of allocations across countries is based on four indicators. ► The four indicators are GDP/capita, GHG/GDP, population growth, and GHG trend. ► Any possible agreement on effort comparability needs a combination of indicators. ► We analyse the role played by the degree of flexibility in global carbon trading

Advanced biofuels - GHG emissions and energy balances. A report to IEA bioenergy task 39

In this work, a number of advanced biofuel pathways were examined with respect to their energy balances and GHG emission performance. Some of these pathways have relatively detailed public techno-economic modelling studies available on which the energy and GHG lifecycle modelling has been based. However there is a continuum in the quality of publicly available data and, for some of the pathways a significant number of assumptions had to be made in order to generate results. Some caution is therefore warranted when the results of different systems are compared. Furthermore, none of the modelling data is based on actual operating systems, as the processes being assessed are not yet in commercial operation; rather, they are each in different stages of research, development and demonstration.

Energy and GHG Analysis of Rural Household Biogas Systems in China

2014-02-01

Full Text Available The Chinese government has taken great efforts to popularize rural household scale biogas digesters, since they are regarded as an effective approach to address energy shortage issues in rural areas and as a potential way of reducing greenhouse gas (GHG emissions. Focusing on a typical rural household biogas system, the aim of this study is to systematically quantify its total direct and indirect energy, concentrating on non-renewable energy and the associated GHG emission cost over the entire life cycle to understand its net dynamic benefits. The results show that the total energetic cost for biogas output is 2.19 J/J, of which 0.56 J is from non-renewable energy sources and the GHG emission cost is 4.54 × 10−5 g CO2-equivalent (CO2-eq, with respect to its design life cycle of 20 years. Correspondingly, a net non-renewable energy saving of 9.89 × 1010 J and GHG emission reduction of 50.45 t CO2-eq can be obtained considering the coal substitution and manure disposal. However, it must be run for at least 10 and 3 years, to obtain positive net non-renewable energy savings and GHG emission reduction benefits, respectively. These results have policy implications for development orientation, follow-up services, program management and even national financial subsidy methods.

Greenhouse gas emissions from cities and regions: International implications revealed by Hong Kong

International Nuclear Information System (INIS)

Harris, Paul G.; Chow, Alice S.Y.; Symons, Jonathan

2012-01-01

The diversity of greenhouse gas (GHG) accounting methodologies currently utilized by cities around the world make meaningful comparisons of their emissions almost impossible. Consequently, the 2010 United Nations International Standard for Determining Greenhouse Gas Emissions for Cities promotes a “harmonized protocol for quantifying the GHG emissions attributable to cities and local regions.” The UN's common standard has important implications for comparison, benchmarking and policy assessment related to energy policies. This paper uses Hong Kong as a case study to illustrate these implications. Hong Kong's per capita contribution to GHG emissions are among the highest in the world, yet the local government's official statistics indicate emissions that are far below those reported by most affluent economies. This discrepancy arises from a reporting methodology that does not require inclusion of GHG emissions linked to consumption of imported goods or emissions from aviation and shipping. The Hong Kong case reveals that current inventories do not provide sufficient information to guide policymaking related to energy and climate change. They also do not provide adequate information for comparing policies of cities internationally. Alternative emissions-reporting standards that focus more on pollution from consumption will create avenues for more effective climate-related policies. - Highlights: ► Flawed GHG inventory methodologies can lead cities to adopt misguided policies. ► Diverse GHG inventory methodologies make meaningful comparisons among cities difficult. ► A Hong Kong case study highlights that GHG inventories can misrepresent cities' climate impacts. ► City inventories often exclude GHG emissions linked to imports, aviation and shipping. ► The International Standard for Determining GHG Emissions for Cities can assist climate policy.

After electricity generation, the oil and gas sector is the most emission intensive industry in Canada. This paper presents statistical data and research by the Canadian Energy Research Institute (CERI). The aim of the research was to provide a comparative evaluation between Alberta's energy consumption and Canada-wide consumption. Data revealed that energy consumption and greenhouse gas (GHG) emissions have increased faster in Alberta in comparison to the rest of Canada, but have slowed since 1997, while emissions in the rest of Canada still continued to increase. Aggregate emission intensities were presented. It was noted that there were no significant changes in fuel mix in either Alberta or the country as a whole. Key factors contributing to rapid increase in energy consumption and GHG emissions after 1996 were: increased energy intensive production and increased use of natural gas. Charts of oil and gas use were presented in energy consumption, economic output and GHG emissions, also indicating that Canadian trends followed Alberta trends. A list of reduction measures in the oil and gas sector were provided, with figures of total reductions and cost. Future actions were outlined and included: ratification of the Kyoto Accord, the negotiation of sectoral agreements, important elements such as cost cap and percentages of reduction; the limited ability to reduce emissions at lower cost per tonne within the oil and gas sector; technology breakthroughs; and adoption of new practices such as the use of alternate fuels in energy intensive processes. tabs, figs

Alvarenga, Rafael [BHP Billiton Base Metals (Australia)

2010-07-01

Global warming due to various reasons but especially to emission of green house gases (GHGs) has become a cause for serious concern. This paper discusses the steps taken by BHP Billiton to reduce energy consumption and GHG emissions using cost curves. According to forecasts, global warming is expected to impact Chile badly and the rise in temperature could be between 1 and more than 5 degrees Celsius. Mining in Chile consumes a lot of energy, particularly electricity. Total energy and electricity consumption in 2007 was 13 and 36 % respectively. BHP base metals developed a set of abatement cost curves for energy and GHG in Chile and these are shown in figures. The methodology for the curves consisted of consultant visits to each mine operation. The study also includes mass energy balance and feasibility maps. The paper concludes that it is important to evaluate the potential for reducing emissions and energy and their associated costs.

Sensitivity analysis of GHG emissions from biofuels in Canada

International Nuclear Information System (INIS)

2006-01-01

This report identified key factors influencing the life-cycle greenhouse gas (GHG) emissions of ethanol and biodiesel production pathways in Canada. The report was prepared for use by policy makers in order to facilitate decision making that positively impacts the lifecycle GHG performance of renewable fuels. Four ethanol production pathways were considered: (1) ethanol production from corn; (2) ethanol production from wheat in conventional starch ethanol facilities; (3) ethanol produced from wheat straw using lignocellulosic technology; and (4) ethanol from sugar cane imported into Canada. For the pathway analysis, ethanols were blended at low levels with sulphur gasoline or used as E85 with low levels of gasoline. All ethanol scenarios were modelled for light duty vehicles. Results of the study demonstrated that all 4 pathways showed significant reductions in GHG emissions when compared to low sulphur gasoline. Differences in vehicle operation emissions between gasoline and ethanol-blended gasoline were related to a combination of the difference in the carbon content per unit of energy and the energy efficiency improvement. The study examined land use changes and feedstock production as well as all other lifecycle processes for diesel, canola, soy, palm, tallow, tallow grease, and yellow grease. A variety of transportation distances were considered. It was concluded that the alternative uses of co-products such as combustion to provide thermal energy resulted in improved GHG results. 17 refs., 117 tabs., 13 figs

The definition of oil is shifting in considerable ways. Conventional oil resources are declining as oil sands, heavy oils, and others emerge. Technological advances mean that these unconventional hydrocarbons are now viable resources. Meanwhile, scientific evidence is mounting that climate change is occurring. The oil sector is responsible for 35% of global greenhouse gas (GHG) emissions, but the climate impacts of these new unconventional oils are not well understood. As such, the Oil Climate Index (OCI) project has been an international effort to evaluate the total life-cycle environmental GHG emissions of different oil fields globally. Over the course of the first and second phases of the project, 30 and 75 global oil fields have been investigated, respectively. The 75 fields account for about 25% of global oil production. For the third phase of the project, it is aimed to expand the OCI to contain closing to 100% of global oil production; leading to the analysis of 8000 fields. To accomplish this, a robust database system is required to handle and manipulate the data. Therefore, the integration of the data into the computer science language SQL (Structured Query Language) was performed. The implementation of SQL allows users to process the data more efficiently than would be possible by using the previously established program (Microsoft Excel). Next, a graphic user interface (gui) was implemented, in the computer science language of C#, in order to make the data interactive; enabling people to update the database without prior knowledge of SQL being necessary.

Voluntary GHG reduction of industrial sectors in Taiwan.

Chen, Liang-Tung; Hu, Allen H

2012-08-01

The present paper describes the voluntary greenhouse gas (GHG) reduction agreements of six different industrial sectors in Taiwan, as well as the fluorinated gases (F-gas) reduction agreement of the semiconductor and Liquid Crystal Display (LCD) industries. The operating mechanisms, GHG reduction methods, capital investment, and investment effectiveness are also discussed. A total of 182 plants participated in the voluntary energy saving and GHG reduction in six industrial sectors (iron and steel, petrochemical, cement, paper, synthetic fiber, and textile printing and dyeing), with 5.35 Mt reduction from 2004 to 2008, or 33% higher than the target goal (4.02 Mt). The reduction accounts for 1.6% annual emission or 7.8% during the 5-yr span. The petrochemical industry accounts for 49% of the reduction, followed by the cement sector (21%) and the iron and steel industry (13%). The total investment amounted to approximately USD 716 million, in which, the majority of the investment went to the modification of the manufacturing process (89%). The benefit was valued at around USD 472 million with an average payback period of 1.5 yr. Moreover, related energy saving was achieved through different approaches, e.g., via electricity (iron and steel), steam and oil consumption (petrochemical) and coal usage (cement). The cost for unit CO(2) reduction varies per industry, with the steel and iron industrial sector having the highest cost (USD 346 t(-1) CO(2)) compared with the average cost of the six industrial sectors (USD 134 t(-1) CO(2)). For the semiconductor and Thin-Film Transistor LCD industries, F-gas emissions were reduced from approximately 4.1 to about 1.7 Mt CO(2)-eq, and from 2.2 to about 1.1 Mt CO(2)-eq, respectively. Incentive mechanisms for participation in GHG reduction are also further discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Appropriate agricultural practices for carbon sequestration and emission mitigation have a significant influence on global climate change. However, various agricultural practices on farmland carbon sequestration usually have a major impact on greenhouse gas (GHG) emissions. It is very important to accurately quantify the effect of agricultural practices. This study developed a platform-the Denitrification Decomposition (DNDC) online model-for simulating and evaluating the agricultural carbon sequestration and emission mitigation based on the scientific process of the DNDC model, which is widely used in the simulation of soil carbon and nitrogen dynamics. After testing the adaptability of the platform on two sampling fields, it turned out that the simulated values matched the measured values well for crop yields and GHG emissions. We used the platform to estimate the effect of three carbon sequestration practices in a sampling field: nitrogen fertilization reduction, straw residue and midseason drainage. The results indicated the following: (1) moderate decrement of the nitrogen fertilization in the sampling field was able to decrease the N₂O emission while maintaining the paddy rice yield; (2) ground straw residue had almost no influence on paddy rice yield, but the CH₄ emission and the surface SOC concentration increased along with the quantity of the straw residue; (3) compared to continuous flooding, midseason drainage would not decrease the paddy rice yield and could lead to a drop in CH₄ emission. Thus, this study established the DNDC online model, which is able to serve as a reference and support for the study and evaluation of the effects of agricultural practices on agricultural carbon sequestration and GHG emissions mitigation in China.

Modeling the Heterogeneous Effects of GHG Mitigation Policies on Global Agriculture and Forestry

Agriculture and forestry are envisioned as potentially key sectors for climate change mitigation policy, yet the depth of analysis of mitigation options and their economic consequences remains remarkably shallow in comparison to that for industrial mitigation. Farming and land use change - much of it induced by agriculture -account for one-third of global greenhouse gas (GHG) emissions. Any serious attempt to curtail these emissions will involve changes in the way farming is conducted, as well as placing limits on agricultural expansion into areas currently under more carbon-intensive land cover. However, agriculture and forestry are extremely heterogeneous, both in the technology and intensity of production, as well as in the GHG emissions intensity of these activities. And these differences, in turn, give rise to significant changes in the distribution of agricultural production, trade and consumption in the wake of mitigation policies. This paper assesses such distributional impacts via a global economic analysis undertaken with a modified version of the GTAP model. The paper builds on a global general equilibrium GTAP-AEZ-GHG model (Golub et al., 2009). This is a unified modeling framework that links the agricultural, forestry, food processing and other sectors through land, and other factor markets and international trade, and incorporates different land-types, land uses and related CO2 and non-CO2 GHG emissions and sequestration. The economic data underlying this work is the global GTAP data base aggregated up to 19 regions and 29 sectors. The model incorporates mitigation cost curves for different regions and sectors based on information from the US-EPA. The forestry component of the model is calibrated to the results of the state of the art partial equilibrium global forestry model of Sohngen and Mendelson (2007). Forest carbon sequestration at both the extensive and intensive margins are modeled separately to better isolate land competition between

Can we trust corporates GHG inventories? An investigation among Canada's large final emitters

Talbot, David; Boiral, Olivier

2013-01-01

In the public sphere and the literature on climate strategies, the measurability of corporate GHG emissions tends to be taken for granted, and few empirical studies have examined the reliability of such data. The present case study, which was conducted among 10 Canadian companies considered as large final emitters and three auditing firms, focuses on the factors which could affect the perceived credibility of GHG inventories and the strategic implications of these. The qualitative, inductive study allows identifying three main factors which affect trust in business inventories: technical issues and complexity of GHG measurements, lack of transparency on the part of the companies and unreliability of verification mechanisms. The study also makes it possible to evaluate the implications of uncertainties concerning GHG inventories which are of strategic importance for companies and policy makers. While the reliability of GHG measurement is taken for granted at the political level, uncertainties in this area can in fact have a huge impact on the establishment of the cap and trade system. The study also contributes to the literature on carbon accounting by shedding light on underexplored ethical issues, including the lack of independence of auditors and its implications. - Highlights: • The complexity of GHG emission measurement is underestimated in the public sphère. • The data disclosed by companies to the different stakeholders lack transparency. • The auditors' lack of competence and independence undermine the credibility of audit reports

Whether greenhouse gas emissions from international shipping are a type of marine pollution is a controversial issue and is currently open to debate. This article examines the current treaty definitions of marine pollution, and applies them to greenhouse gas emissions from ships. Based on the legal analysis of treaty definitions and relevant international and national regulation on this issue, this article asserts that greenhouse gas emissions from international shipping are a type of ‘conditional’ marine pollution. - Highlights: • Greenhouse gas (GHG) emissions from international shipping are a type of ‘conditional’ marine pollution. • Shipping CO 2 may be treated as marine pollution under the 1972 London Dumping Convention. • Countries have adopted different legislation concerning the legal nature of GHG emissions from ships. • Regulating CO 2 emissions from ships as marine pollution may expedite global GHG emissions reduction.

The increase in number of vehicles in metropolitan cities has resulted in increase of greenhouse gas (GHG) emissions in urban environment. In this study, emission load of GHGs (CO, N 2 O, CO 2 ) from Chandigarh road transport sector has been estimated using Vehicular Air Pollution Inventory (VAPI) model, which uses emission factors prevalent in Indian cities. Contribution of 2-wheelers (2-w), 3-wheelers (3-w), cars, buses, and heavy commercial vehicles (HCVs) to CO, N 2 O, CO 2 , and total GHG emissions was calculated. Potential for GHG mitigation through clean development mechanism (CDM) in transport sector of Chandigarh under two scenarios, i.e., business as usual (BAU) and best estimate scenario (BES) using VAPI model, has been explored. A major contribution of GHG load (~ 50%) in Chandigarh was from four-wheelers until 2011; however, it shows a declining trend after 2011 until 2020. The estimated GHG emission from motor vehicles in Chandigarh has increased more than two times from 1065 Gg in 2005 to 2486 Gg by 2011 and is expected to increase to 4014 Gg by 2020 under BAU scenario. Under BES scenario, 30% of private transport has been transformed to public transport; GHG load was possibly reduced by 520 Gg. An increase of 173 Gg in GHGs load is projected from additional scenario (ADS) in Chandigarh city if all the diesel buses are transformed to CNG buses by 2020. Current study also offers potential for other cities to plan better GHG reduction strategies in transport sector to reduce their climate change impacts.

Under its Kyoto and EU obligations, Greece has committed to a greenhouse gas (GHG) emissions increase of at most 25% compared to 1990 levels, to be achieved during the period 2008-2012. Although this restriction was initially regarded as being realistic, information derived from GHG emissions inventories shows that an increase of approximately 28% has already taken place between 1990 and 2005, highlighting the need for immediate action. This paper explores the reallocation of production in Greece, on a sector-by-sector basis, in order to meet overall demand constraints and GHG emissions targets. We pose a constrained optimization problem, taking into account the Greek environmental input-output matrix for 2005, the amount of utilized energy and pollution reduction options. We examine two scenarios, limiting fluctuations in sectoral production to at most 10% and 15%, respectively, compared to baseline (2005) values. Our results indicate that (i) GHG emissions can be reduced significantly with relatively limited effects on GVP growth rates, and that (ii) greater cutbacks in GHG emissions can be achieved as more flexible production scenarios are allowed.

Assessment of GHG emissions of biomethane from energy cereal crops in Umbria, Italy

Buratti, C.; Barbanera, M.; Fantozzi, F.

2013-01-01

Highlights: • GHG emissions of biomethane from energy crops cultivated in a central Italian farm were investigated. • Electricity consumption of the biogas plant was monitored. • Current scenario does not allow to achieve a GHG saving according to Renewable Energy Directive. • GHG emissions could be reduced by covering the storage tanks of digestate and installing a CHP plant. - Abstract: Biomethane from energy crops is a renewable energy carrier and therefore it potentially contributes to climate change mitigation. However, significant greenhouse gas (GHG) emissions resulting from cultivation and processing must be considered. Among those, the production and use of nitrogen fertilizers, the resulting nitrous oxide (N 2 O) emissions, the methane emissions from digestate storage and the energy consumption of the biogas plant are crucial factors. In the present paper an integrated life cycle assessment (LCA) of GHG emissions from biomethane production is carried out, taking into account own measurements and experience data from a modern biogas plant located in Umbria, Italy. The study is also focused on the electricity consumption of the biogas plant, assessing the specific absorption power of each machinery. The analysis is based on the methodology defined by the European Union Renewable Energy Directive 2009/28/EC (RED). The main result is that the biomethane chain exceeds the minimum value of GHG saving (35%) mainly due to the open storage of digestate. However by varying the system, using heat and electricity from a biogas CHP plant and covering digestate storage tank, a reduction of 68.9% could be obtained

Strategies to reduce emissions in all areas of future research were also provided. tabs, figs.

Lifecycle GHG emissions of palm biodiesel: Unintended market effects negate direct benefits of the Malaysian Economic Transformation Plan (ETP)

International Nuclear Information System (INIS)

Abdul-Manan, Amir F.N.

2017-01-01

Biodiesel expansion can lead to unintended effects that offset the direct GHG benefits of biofuels. Two documented unintended effects are the indirect land use change (ILUC) and indirect energy use change (IEUC). ILUC has been included in many lifecycle GHG studies of biofuels, but IEUC has remained relatively elusive. This paper presents an updated assessment of the lifecycle GHG emissions of palm biodiesel from Malaysia and, for the first time, incorporating the two estimated indirect effects simultaneously. Future GHG emissions of palm biodiesel are projected by taking into account of Malaysia's Economic Transformation Programme (ETP) that aims to reform the oil palm industry in order to achieve a high-income nation. Uncertainties associated with lifecycle GHG models were dealt with using Monte Carlo simulation in order to identify the breadth and likelihood of GHG reductions relative to petroleum-based fuels in the context of the European directives. This study has shown that the ETP, if successfully implemented, can significantly improve the direct GHG emissions of palm biodiesel, but the benefits are offset by the rise in global emissions due to ILUC and IEUC. Biofuel policies should also include IEUC, in addition to ILUC, to avoid GHG emissions leakages. - Highlights: • Estimate current and future lifecycle GHG emissions of Malaysian palm biodiesel. • Evaluate the GHG effects of Malaysia's Economic Transformation Plan (ETP). • Direct GHG benefits of biodiesel offset by indirect market effects. • Palm biodiesel unlikely to enable global GHG emissions reductions. • Global biofuel policy must account for indirect effects.

There is a growing concern that urban sprawl and highly dispersed urban infrastructure in cities is posing significant environmental impacts. However, there is no agreement on the suitability of interventions such as population intensification on reducing environmental impacts. This paper investigated the connection between population intensification and environmental impact in water distribution networks. Specifically, it examined the relationship between population density, annual per capita energy use, and annual per capita greenhouse gas (GHG) emissions in water distribution networks. It also examined which population densities produce low levels of annual per capita energy use and GHG emissions. An analytical model of a trunk main was developed to connect population density to energy use and GHG emissions. The model considered energy use in five life activities of the trunk main, namely pipe fabrication, pipe repair, water pumping, and pipe recycling and/or disposal. The energy use model was combined with emission factors and electricity fuel-source mixtures from four Canadian regions (Atlantic Provinces, Quebec, Ontario, and Alberta) to compute representative levels of annual per capita GHGs emitted by the trunk main. It was concluded that increasing population density from 10 ca/ha to 150 ca/ha reduced energy use and GHG emissions by 67per cent and that increasing population density beyond 150 ca/ha produces no significant decrease in annual per capita energy use and GHG emissions. Further analysis on looped networks is required to verify these preliminary findings. 10 refs., 3 tabs., 2 figs.

A consumption-based GHG inventory for the U.S. state of Oregon.

Many U.S. states conduct greenhouse gas (GHG) inventories to inform their climate change planning efforts. These inventories usually follow a production-based method adapted from the Intergovernmental Panel on Climate Change. States could also take a consumption-based perspective, however, and estimate all emissions released to support consumption in their state, regardless of where the emissions occur. In what may be the first such comprehensive inventory conducted for a U.S. state, we find that consumption-based emissions for Oregon are 47% higher than those released in-state. This finding implies that Oregon's contribution to global greenhouse gas emissions (carbon footprint) is considerably higher than traditional production-based methods would suggest. Furthermore, the consumption-based inventory helps highlight the role of goods and services (and associated purchasing behaviors) more so than do production-based methods. Accordingly, a consumption-based perspective opens new opportunities for many states and their local government partners to reduce GHG emissions, such as initiatives to advance lower-carbon public sector or household consumption, that are well within their sphere of influence. State and local governments should consider conducting consumption-based GHG inventories and adopting consumption-based emission reductions targets in order to broaden the reach and effectiveness of state and local actions in reducing global GHG emissions. Consumption-based frameworks should be viewed as a complement to, but not a substitute for, production-based (in-state) GHG emissions inventories and targets.

General guidance and procedures for estimating and reporting national GHG emissions for agriculture

International Nuclear Information System (INIS)

Rypdal, K.

2002-01-01

Greenhouse gas (GHG) emissions from agriculture account for a large share of total GHG emissions in most countries. Methane from ruminants, animal manure and rice fields, and nitrous oxide from agricultural soils are among the most important sources. In general, these emission estimates also are more uncertain than most other parts of the GHG emission inventory. IPCC has developed guidelines for estimating and reporting emissions of GHG. These guidelines shall be followed to secure complete, consistent, accurate and transparent reporting of emissions. However, the recommended methodologies are tiered, and choice of methods shall preferably reflect national circumstances, the national importance of a source, and different resources to prepare inventories. A country may also apply a national methodology given that it is well documented and not in conflict with good practice. Emission data reported under the United Nation Framework Convention on Climate Change are subject to external control, and the methodologies are reviewed by experts on agricultural inventories. (au)

This paper presents life-cycle-analysis (LCA) energy consumption (EC) and greenhouse gas (GHG) emissions of China's current six biofuel pathways, which are: corn-derived ethanol (CE); cassava-derived ethanol (KE); sweet sorghum-derived ethanol (SE); soybean-derived bio-diesel (SB); jatropha fruit-derived bio-diesel (JB); and used cooking oil (UCO)-derived bio-diesel (UB). The tool utilized here is the WTW (Well-to-Wheels) module of Tsinghua-CA3EM model covering the entire lifecycle including: raw materials cultivation (or feedstock collection); fuel production; transportation and distribution; and application in automobile engines, compared with Conventional Petroleum-based gasoline and diesel Pathways (CPP). The results indicate: (1) the fossil energy inputs are about 1.0-1.5 times the energy contained in the fuel for the CE, SE and SB pathways, but 0.5-0.9 times for the KE, UB and JB pathways; (2) compared with CPP, the JB, KE and UB pathways can reduce both fossil fuel consumption and GHG emissions; the CE and SB pathways can only reduce fossil fuel consumption, but increase GHG emission; the SE pathway increases not only fossil fuel consumption but also GHG emission; and (3) the main factors inducing high EC and GHG emission levels include: high EC levels during the fuel production stage and high fertilizer application rates during the planting of raw feedstocks. Conclusions are that of the aforementioned biofuel pathways in China: (1) only the JB, KE and UB pathways have energy-saving merits as indicated by the LCA energy inputs and outputs; (2) compared with CPP, all but the SE pathway reduces fossil fuel consumption.

The GHG-CCI project is one of several projects of ESA's Climate Change Initiative (CCI), which will deliver various Essential Climate Variables (ECVs). The goal of GHG-CCI is to deliver global satellite-derived data sets of the two most important anthropogenic greenhouse gases (GHGs) carbon dioxide (CO2) and methane (CH4) suitable to obtain information on regional CO2 and CH4 surface sources and sinks as needed for better climate prediction. The GHG-CCI core ECV data products are column-averaged mole fractions of CO2 and CH4, i.e., XCO2 and XCH4, retrieved from SCIAMACHY on ENVISAT and TANSO on GOSAT. Other satellite instruments will be used to provide constraints in upper layers such as IASI, MIPAS, and ACE-FTS. Which of the advanced algorithms, which are under development, will be the best for a given data product still needs to be determined. For each of the 4 GHG-CCI core data products - XCO2 and XCH4 from SCIAMACHY and GOSAT - several algorithms will be further developed and the corresponding data products will be inter-compared to identify which data product is the most appropriate. This includes comparisons with corresponding data products generated elsewhere, most notably with the operational data products of GOSAT generated at NIES and the NASA/ACOS GOSAT XCO2 product. This activity, the so-called "Round Robin exercise", will be performed in the first two years of this project. At the end of the 2 year Round Robin phase a decision will be made which of the algorithms performs best. The selected algorithms will be used to generate the first version of the ECV GHG. In the last six months of this 3 year project the resulting data products will be validated and made available to all interested users. In the presentation and overview about this project will be given. Focus will be on a discussion and intercomparison of the various data products focusing on CO2.

Review of the Fuel Saving, Life Cycle GHG Emission, and Ownership Cost Impacts of Lightweighting Vehicles with Different Powertrains.

2017-08-01

The literature analyzing the fuel saving, life cycle greenhouse gas (GHG) emission, and ownership cost impacts of lightweighting vehicles with different powertrains is reviewed. Vehicles with lower powertrain efficiencies have higher fuel consumption. Thus, fuel savings from lightweighting internal combustion engine vehicles can be higher than those of hybrid electric and battery electric vehicles. However, the impact of fuel savings on life cycle costs and GHG emissions depends on fuel prices, fuel carbon intensities and fuel storage requirements. Battery electric vehicle fuel savings enable reduction of battery size without sacrificing driving range. This reduces the battery production cost and mass, the latter results in further fuel savings. The carbon intensity of electricity varies widely and is a major source of uncertainty when evaluating the benefits of fuel savings. Hybrid electric vehicles use gasoline more efficiently than internal combustion engine vehicles and do not require large plug-in batteries. Therefore, the benefits of lightweighting depend on the vehicle powertrain. We discuss the value proposition of the use of lightweight materials and alternative powertrains. Future assessments of the benefits of vehicle lightweighting should capture the unique characteristics of emerging vehicle powertrains.

Nguyen, Thu Lan Thi; Gheewala, Shabbir H.; Garivait, Savitri

2007-01-01

Since 2001, in order to enhance ethanol's cost competitiveness with gasoline, the Thai government has approved the exemption of excise tax imposed on ethanol, controlling the retail price of gasohol (a mixture of ethanol and gasoline at a ratio of 1:9) to be less than that of octane 95 gasoline, within a range not exceeding 1.5 baht a litre. The policy to promote ethanol for transport is being supported by its positive effects on energy security and climate change mitigation. An analysis of energy, greenhouse gas (GHG) balances and GHG abatement cost was done to evaluate fuel ethanol produced from cassava in Thailand. Positive energy balance of 22.4 MJ/L and net avoided GHG emission of 1.6 kg CO 2 eq./L found for cassava-based ethanol (CE) proved that it would be a good substitute for gasoline, effective in fossil energy saving and GHG reduction. With a GHG abatement cost of US$99 per tonne of CO 2 , CE is rather less cost effective than the many other climate strategies relevant to Thailand in the short term. Opportunities for improvements are discussed to make CE a reasonable option for national climate policy

long wave radiation fluxes. NIST is working with partner institutions to develop the measurement science and measurement tools needed to improve the accuracy and comparability of surface-based measurement approaches for MRV purposes. The current project phase is focused on determination of emission source location with a spatial resolution of approximately 1 km2 and of sources strength to within 20% uncertainty, in part for comparison to inventories. Additionally, the demonstration of a robust, dense observing network methodology will provide a means to characterize urban GHG domes and provides a calibration method for remote sensing measurements whether taken by on-orbit, terrestrial, or airborne observations. The Indianapolis Flux experiment is the initial research effort to demonstrate this approach to emissions verification. Lessons learned in INFLUX are expected to be extensible to other urban and regional settings, suggesting further research to be conducted for areas having significantly different terrain and meteorology.

Whole farm quantification of GHG emissions within smallholder farms in developing countries

International Nuclear Information System (INIS)

Seebauer, Matthias

2014-01-01

The IPCC has compiled the best available scientific methods into published guidelines for estimating greenhouse gas emissions and emission removals from the land-use sector. In order to evaluate existing GHG quantification tools to comprehensively quantify GHG emissions and removals in smallholder conditions, farm scale quantification was tested with farm data from Western Kenya. After conducting a cluster analysis to identify different farm typologies GHG quantification was exercised using the VCS SALM methodology complemented with IPCC livestock emission factors and the cool farm tool. The emission profiles of four farm clusters representing the baseline conditions in the year 2009 are compared with 2011 where farmers adopted sustainable land management practices (SALM). The results demonstrate the variation in both the magnitude of the estimated GHG emissions per ha between different smallholder farm typologies and the emissions estimated by applying two different accounting tools. The farm scale quantification further shows that the adoption of SALM has a significant impact on emission reduction and removals and the mitigation benefits range between 4 and 6.5 tCO 2  ha −1  yr −1 with significantly different mitigation benefits depending on typologies of the crop–livestock systems, their different agricultural practices, as well as adoption rates of improved practices. However, the inherent uncertainty related to the emission factors applied by accounting tools has substantial implications for reported agricultural emissions. With regard to uncertainty related to activity data, the assessment confirms the high variability within different farm types as well as between different parameters surveyed to comprehensively quantify GHG emissions within smallholder farms.

2015-01-01

This paper presents a new approach for the estimation of energy-related GHG (greenhouse gas) emissions at the national level that combines the simplicity of the concept of GHG intensity and the generalization capabilities of ANNs (artificial neural networks). The main objectives of this work includes the determination of the accuracy of a GRNN (general regression neural network) model applied for the prediction of EC (energy consumption) and GHG intensity of energy consumption, utilizing general country statistics as inputs, as well as analysis of the accuracy of energy-related GHG emissions obtained by multiplying the two aforementioned outputs. The models were developed using historical data from the period 2004–2012, for a set of 26 European countries (EU Members). The obtained results demonstrate that the GRNN GHG intensity model provides a more accurate prediction, with the MAPE (mean absolute percentage error) of 4.5%, than tested MLR (multiple linear regression) and second-order and third-order non-linear MPR (multiple polynomial regression) models. Also, the GRNN EC model has high accuracy (MAPE = 3.6%), and therefore both GRNN models and the proposed approach can be considered as suitable for the calculation of GHG emissions. The energy-related predicted GHG emissions were very similar to the actual GHG emissions of EU Members (MAPE = 6.4%). - Highlights: • ANN modeling of GHG intensity of energy consumption is presented. • ANN modeling of energy consumption at the national level is presented. • GHG intensity concept was used for the estimation of energy-related GHG emissions. • The ANN models provide better results in comparison with conventional models. • Forecast of GHG emissions for 26 countries was made successfully with MAPE of 6.4%

Currently, transport is highly dependent on fossil fuels and responsible for about 23% of world energy-related GHG (greenhouse gas) emissions. Ethanol from sugar cane and corn emerges as an alternative for gasoline in order to mitigate GHG emissions. Additionally, deeper offshore drilling projects such as in the Brazilian Pre-Salt reservoirs and mining projects of nonconventional sources like Tar Sands in Canada could be a solution for supplying demand of fossil fuels in the short and midterm. Based on updated literature, this paper presents an assessment of GHG emissions for four different fuels: ethanol from sugar cane and from corn and gasoline from conventional crude oil and from tar sands. An Ecological Footprint analysis is also presented, which shows that ethanol from sugar cane has the lowest GHG emissions and requires the lowest biocapacity per unit of energy produced among these fuels. Finally, an analysis using the Embodied Water concept is made with the introduction of a new concept, the "CO(2)-Water", to illustrate the impacts of releasing carbon from underground to atmosphere and of the water needed to sequestrate it over the life cycle of the assessed fuels. Using this method resulted that gasoline from fossil fuels would indirectly "require" on average as much water as ethanol from sugar cane per unit of fuel energy produced.

Crowd-Sourcing Management Activity Data to Drive GHG Emission Inventories in the Land Use Sector

Science.gov (United States)

Paustian, K.; Herrick, J.

2015-12-01

Greenhouse gas (GHG) emissions from the land use sector constitute the largest source category for many countries in Africa. Enhancing C sequestration and reducing GHG emissions on managed lands in Africa has to potential to attract C financing to support adoption of more sustainable land management practices that, in addition to GHG mitigation, can provide co-benefits of more productive and climate-resilient agroecosystems. However, robust systems to measure and monitor C sequestration/GHG reductions are currently a significant barrier to attracting more C financing to land use-related mitigation efforts.Anthropogenic GHG emissions are driven by a variety of environmental factors, including climate and soil attributes, as well as human-activities in the form of land use and management practices. GHG emission inventories typically use empirical or process-based models of emission rates that are driven by environmental and management variables. While a lack of field-based flux and C stock measurements are a limiting factor for GHG estimation, we argue that an even greater limitation may be availabiity of data on the management activities that influence flux rates, particularly in developing countries in Africa. In most developed countries there is a well-developed infrastructure of agricultural statistics and practice surveys that can be used to drive model-based GHG emission estimations. However, this infrastructure is largely lacking in developing countries in Africa. While some activity data (e.g. land cover change) can be derived from remote sensing, many key data (e.g., N fertilizer practices, residue management, manuring) require input from the farmers themselves. The explosive growth in cellular technology, even in many of the poorest parts of Africa, suggests the potential for a new crowd-sourcing approach and direct engagement with farmers to 'leap-frog' the land resource information model of developed countries. Among the many benefits of this approach

Target-aimed versus wishful-thinking in designing efficient GHG reduction strategies for a metropolitan city: Taipei

Liu, C.-M.; Liou, M.-L.; Yeh, S.-C.; Shang, N.-C.

2009-01-01

In recent years, many national and local governments claim for a specific GHG (greenhouse gas) reduction goal targeted for many years later. In 2005, the Taipei City government announced that Taipei's total GHG emission in 2015 will reach the same level as that in 2005 and then down to 75% of that level at year 2030. However, based on the estimated energy consumption and GHG emission and the proposed emission reduction plans from the local government, it is clear that these goals are not going to be accomplished. In Taipei, the residential and commercial sector contributes more than 78% of the total GHG emission. Thus, in a business as usual scenario, the total GHG emission in 2030 would be 79% more than that in 2005, far more than the target value proclaimed. As many key factors are uncontrollable by the local government, a target-aimed strategy designing process by looking into changes in Taipei and identifying major targets is proposed in this study. It is demonstrated that such a universally applicable approach will give more confidence to the public on working toward the expected GHG reduction goal

The purpose of this research is to identify the problems and measures for reduction of GHG emissions by conducting research on the GHG emission trends in the energy-conversion, industry, public and transportation sectors, and policies and regulations. Japan`s total emission of CO2 in FY 1994 was 343 million tons in terms of carbon, and the emission per capita was 2.74 tons. These amounts were 7% increase in total CO2 emissions and 6% increase in the emission per capita compared with those in FY 1990. There were high increases in the public and transportation sectors. This trend is expected to continue in the future. Since more than 90% of CO2 emission is derived from energy origin, the climate change problems mean energy and economic problems. To attain Japan`s goal of the year 2000 with maintaining the appropriate economic growth, it is crucial to accelerate energy-efficiency and introduction of new energy. 19 figs., 28 tabs.

Fossil energy savings and GHG mitigation potentials of ethanol as a gasoline substitute in Thailand

International Nuclear Information System (INIS)

Nguyen, Thu Lan T.; Gheewala, Shabbir H.; Garivait, Savitri

2007-01-01

One of the Thai government's measures to promote ethanol use is excise tax exemption, making gasohol cheaper than gasoline. The policy in favour of biofuels is being supported by their contribution to fossil energy savings and greenhouse gas (GHG) mitigation. An analysis of energy balance (EnB), GHG balance and GHG abatement cost has been done to evaluate molasses-based ethanol (MoE) in Thailand. A positive EnB of 19.2 MJ/L implies that MoE is a good substitute for gasoline, effective in fossil energy savings. GHG balance assessment based on the baseline scenario shows that emissions are most likely to increase with the substitution. Scenarios using biogas captured from spent wash treatment and rice husk to substitute coal used in ethanol conversion give encouraging results in improving the GHG balance. However, the higher price of MoE over gasoline currently has resulted in high GHG abatement costs, even under the best-case scenario. Compared to the many other climate strategies relevant to Thailand, MoE is much less cost effective. Governed by the rule of supply and demand, a strong fluctuation in molasses price is considered the main cause of volatile MoE price. Once supplies are stable, the trend of price drops would make MoE a reasonable option for national climate policy

The title study directly builds on the work previously completed under the EU Transport GHG: Routes to 2050 project. This new work (dubbed EU Transport GHG: Routes to 2050 II) started in January 2011 and was completed in March 2012. The outputs from this new project help to support the Commission in prioritising and developing their strategy for reducing GHG emissions from the transport sector. CE Delft successfully organised the stakeholder engagement as well as the in-depth research on several topics: greenhouse gas (GHG) emissions from vehicle production and infrastructure development, CO2 reduction costs, co-benefits of GHG policies and knock-on consequences of such policies. Also alternative economic development paths were investigated, such as paths that could be less transport intensive, but still deliver increasing levels of prosperity.

Fuel conservation and GHG (Greenhouse gas) emissions mitigation scenarios for China’s passenger vehicle fleet

2011-01-01

Passenger vehicles are the main consumers of gasoline in China. We established a bottom-up model which focuses on the simulation of energy consumptions and greenhouse gas (GHG) emissions growth by China’s passenger vehicle fleet. The fuel conservation and GHG emissions mitigation effects of five measures including constraining vehicle registration, reducing vehicle travel, strengthening fuel consumption rate (FCR) limits, vehicle downsizing and promoting electric vehicle (EV) penetration were evaluated. Based on the combination of these measures, the fuel conservation and GHG emissions mitigation scenarios for China’s passenger vehicle fleet were analyzed. Under reference scenario with no measures implemented, the fuel consumptions and life cycle GHG emissions will reach 520 million tons of oil equivalent (Mtoe) and 2.15 billion tons in 2050, about 8.1 times the level in 2010. However, substantial fuel conservation can be achieved by implementing the measures. By implementing all five measures together, the fuel consumption will reach 138 Mtoe in 2030 and decrease to 126 Mtoe in 2050, which is only 37.1% and 24.3% of the consumption under reference scenario. Similar potential lies in GHG mitigation. The results and scenarios provided references for the Chinese government’s policy-making. -- Highlights: ► We established a bottom-up model to simulate the fuel consumptions and GHG (Greenhouse gas) emissions growth by China’s passenger vehicle fleet. ► Five measures including constraining vehicle registration, reducing vehicle travel, improving fuel efficiency, vehicle downsizing and promoting EV penetration were evaluated. ► The fuel conservation and GHG emissions mitigation scenarios for China’s passenger vehicle fleet were provided as references for policy-making.

Life cycle GHG emissions of sewage sludge treatment and disposal options in Tai Lake Watershed, China

International Nuclear Information System (INIS)

Liu, Beibei; Wei, Qi; Zhang, Bing; Bi, Jun

2013-01-01

The treatment and disposal of sewage sludge generate considerable amounts of greenhouse gases (GHGs) and pose environmental and economic challenges to wastewater treatment in China. To achieve a more informed and sustainable sludge management, this study conducts a life cycle inventory to investigate the GHG performances of six scenarios involving various sludge treatment technologies and disposal strategies. These scenarios are landfilling (S1), mono-incineration (S2), co-incineration (S3), brick manufacturing (S4), cement manufacturing (S5), and fertilizer for urban greening (S6). In terms of GHG emissions, S2 demonstrates the best performance with its large offset from sludge incineration energy recovery, followed by S4 and S6, whereas S1 demonstrates the poorest performance primarily because of its large quantity of methane leaks. The scenario rankings are affected by the assumptions of GHG offset calculation. In most scenarios, GHG performance could be improved by using waste gas or steam from existing facilities for drying sludge. Furthermore, considering the GHG performance along with economic, health, and other concerns, S6 is recommended. We thus suggest that local governments promote the use of composted sludge as urban greening fertilizers. In addition, the use of sludge with 60% water content, in place of the current standard of 80%, in wastewater treatment plants is proposed to be the new standard for Tai Lake Watershed in China. - Highlights: ► Life-cycle GHG emissions of six sludge handling scenarios are examined. ► Scenario rankings are affected by the assumptions of GHG offset calculation. ► Using heat from existing facilities to dry sludge can improve GHG performance. ► Fertilizer for urban greening is recommended due to its integrated performance. ► The sludge water-content standard is suggested to changed from 80% to 60%

These scenarios are landfilling (S1), mono-incineration (S2), co-incineration (S3), brick manufacturing (S4), cement manufacturing (S5), and fertilizer for urban greening (S6). In terms of GHG emissions, S2 demonstrates the best performance with its large offset from sludge incineration energy recovery, followed by S4 and S6, whereas S1 demonstrates the poorest performance primarily because of its large quantity of methane leaks. The scenario rankings are affected by the assumptions of GHG offset calculation. In most scenarios, GHG performance could be improved by using waste gas or steam from existing facilities for drying sludge. Furthermore, considering the GHG performance along with economic, health, and other concerns, S6 is recommended. We thus suggest that local governments promote the use of composted sludge as urban greening fertilizers. In addition, the use of sludge with 60% water content, in place of the current standard of 80%, in wastewater treatment plants is proposed to be the new standard for Tai Lake Watershed in China. - Highlights: ► Life-cycle GHG emissions of six sludge handling scenarios are examined. ► Scenario rankings are affected by the assumptions of GHG offset calculation. ► Using heat from existing facilities to dry sludge can improve GHG performance. ► Fertilizer for urban greening is recommended due to its integrated performance. ► The sludge water-content standard is suggested to changed from 80% to 60%.

This paper presents statistics of greenhouse gas (GHG) emissions for Shell Canada Ltd., one of the largest integrated oil and gas companies in Canada. Strategies for future emissions reductions were also presented. Since 1995, Shell has both set and met targets to reduce emissions in base businesses. They have increased their target reductions to a further 6 per cent by 2008. Strategies included reductions in energy consumption and improvements in energy efficiency. Challenges presented by new governmental regulations were discussed. Alternate energy sources are being considered as a means of expanding the Shell energy business portfolio. Principles and management plans guiding the emissions reduction strategy were presented, as well as details of the Shell management structure and climate change advisory panel. Figures and statistics of emissions reductions were provided in relation to changes in business activity; energy efficiency; formation gas; energy in declining fields; and fuel mix. An emissions forecast to 2010 was presented with newly adjusted goals. In 2003, overall refinery energy efficiency improved by over 4 per cent. Statistics of refinery energy intensity were presented. Exploration and production businesses achieved a reduction of 6 per cent, with energy intensity per unit of production presented. Oil sands projects achieved a GHG emissions intensity of 69 kilograms per barrel of bitumen. In addition, the voluntary GHG management plan introduced a number of offsets including tree planting programs and the purchase of voluntary GHG credits. The methodology used to calculate GHG emissions was also provided. tabs., figs

This paper concentrates on the quantification of greenhouse gas (GHG) emissions of post-consumer plastic waste recovery (material or energy) by considering the influence of the plastic waste quality (high or low), the recycled plastic applications (virgin plastic substitution or non-plastic substitution) and the markets of recovered plastic (regional or global). The aim is to quantify the environmental consequences of different alternatives in order to evaluate opportunities and limitations to select the best and most feasible plastic waste recovery option to decrease the GHG emissions. The methodologies of material flow analysis (MFA) for a time period of thirteen years and consequential life cycle assessment (CLCA) have been integrated. The study focuses on Spain as a representative country for Europe. The results show that to improve resource efficiency and avoid more GHG emissions, the options for plastic waste management are dependent on the quality of the recovered plastic. The results also show that there is an increasing trend of exporting plastic waste for recycling, mainly to China, that reduces the GHG benefits from recycling, suggesting that a new focus should be introduced to take into account the split between local recycling and exporting.

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.

Uncertainty analysis facilitates identification of the most important categories affecting greenhouse gas (GHG) inventory uncertainty and helps in prioritisation of the efforts needed for development of the inventory. This paper presents an uncertainty analysis of GHG emissions of all Kyoto sectors and gases for Finland consolidated with estimates of emissions/removals from LULUCF categories. In Finland, net GHG emissions in 2003 were around 69 Tg (±15 Tg) CO2 equivalents. The uncertainties in forest carbon sink estimates in 2003 were larger than in most other emission categories, but of the same order of magnitude as in carbon stock change estimates in other land use, land-use change and forestry (LULUCF) categories, and in N2O emissions from agricultural soils. Uncertainties in sink estimates of 1990 were lower, due to better availability of data. Results of this study indicate that inclusion of the forest carbon sink to GHG inventories reported to the UNFCCC increases uncertainties in net emissions notably. However, the decrease in precision is accompanied by an increase in the accuracy of the overall net GHG emissions due to improved completeness of the inventory. The results of this study can be utilised when planning future GHG mitigation protocols and emission trading schemes and when analysing environmental benefits of climate conventions

International greenhouse gas trading programs: a discussion of measurement and accounting issues

There is general scientific consensus that global warming is occurring and that this results from human activities, primarily burning fossil fuels. There is also a growing international consensus that the most cost-effective way to slow global warming is to establish international climate change trading programs that let institutions sell greenhouse gas (GHG) reductions in an international trading program. A well designed international GHG trading program could save billions or tens of billions of dollars and could result in a more rapid transfer of cleaner, more modern energy generating, transmitting and using technologies to developing nations. Establishing an international GHG trading program will require the development of international consensus rules on how to value and credit investments, for example in energy efficiency, that result in reduced emissions of greenhouse gases. Such a program would require the development of an international technical agreement on how to value emissions reductions attributed to energy-efficiency investments that reflect realistic estimates of future energy savings--and emissions reductions--that come from those investments. This paper examines five possible approaches for valuing energy savings which might serve as the basis for an international agreement, discusses the strengths and weaknesses of each approach, and discusses lessons learned from conducting this evaluation process

Hydroelectric dams in Amazon as source of GHG

Rosa, L.P.; Schaeffer, R.; Santos, M.A.

1996-01-01

A recent paper by Fearnside points out that hydroelectric development in Amazonia is a significant source of greenhouse gases (GHG) emissions. This conclusion is in contrast to the common belief that hydroelectric dams are better than fossil fuel use in electric power generation, from the view point of GHG emissions. The authors have considered both CH 4 and CO 2 emissions taking into account the instantaneous radiative forcing due to a unit increase in the concentration of gases, the decay times of gases in the atmosphere and the emissions patterns of emissions vary depending on biomass density and type of the forest area flooded, as well as on depth of flooding. As the Fearnside paper is more concerned with CO 2 emissions from the above water biomass, the authors' focus will be restricted to the formulae for calculating the cumulative effect of CO 2

The IPCC Fifth Assessment Report (AR5) accounts an increase of the total annual anthropogenic GHG emissions between 2000 and 2010 that directly came from the transport sector. In 2010, 14% of GHG emissions were released by transport and fossil-fuel-related CO2 emissions reached about 32 GtCO2 per year. The report also considers adaptation and mitigation as complementary strategies for reducing the risks of climate change for sustainable development of urban areas. This paper describes the on-road traffic emission estimated in the framework of a Sardinian regional project [1] for the town of Sassari (Sardinia, Italy), one of the Sardinian areas where the fuel consumption for on-road transportation purposes is higher [2]. The GHG emissions have been accounted (a) by a calculation-based methodology founded on a linear relationship between source activity and emission, and (b) by the COPERT IV methodology through the EMITRA (EMIssions from road TRAnsport) software tool [3]. Inventory data for annual fossil fuel consumption associated with on-road transportation (diesel, gasoline, gas) have been collected through the Dogane service, the ATP and ARST public transport services and vehicle fleet data are available from the Public Vehicle Database (PRA), using 2010 as baseline year. During this period, the estimated CO2 emissions accounts for more than 180,000 tCO2. The calculation of emissions due to on-road transport quantitatively estimates CO2 and other GHG emissions and represents a useful baseline to identify possible adaptation and mitigation strategies to face the climate change risks at municipal level.

2014-01-01

With China’s urbanization and motorization, greenhouse gas (GHG) emissions from urban passenger transport increased rapidly over recent years. As we estimated, China’s urban passenger transport associated motorized travel, energy consumption and lifecycle GHG emissions reached 2815 billion passenger kilometers (pkm), 77 million tons of oil equivalent (toe) and 335 million ton CO 2 equivalent in 2010, over half of which were located in eastern provinces. Over national level, GHG emissions by private passenger vehicles, business passenger vehicles, taxis, motorcycles, E-bikes, transit buses and urban rails accounted for 57.7%, 13.0%, 7.7%, 8.6%, 1.8%, 10.5% and 0.7% of the total. Significant regional disparity was observed. The province-level per capita GHG emissions ranged from 285 kg/capita in Guizhou to 1273 kg/capita in Beijing, with national average of 486 kg/capita. Depending on province context and local policy orientation, the motorization pathways of China’s several highest motorized provinces are quite diverse. We concluded that motorization rate and transport structure were the substantial factors determining urban passenger transport associated GHG emissions. Considering the great potential of urban passenger transport growth in China, policies guiding the optimization of transport structure should be in place with priority in eastern provinces. - Highlights: • Province-leveled motorized travel, energy consumption and GHG emissions in China were studied. • Significant regional disparities on urban passenger transport were observed. • Region-specific sustainable transport energy policies were discussed

The EU has committed itself to meet an 8% greenhouse gas (GHG) reduction target level following the Kyoto agreement. Therefore, the EU Commission has just proposed a new directive establishing a framework for GHG emissions trading within the European Union. This proposal is to outcome a policy process started by the EU Commission and its Green Paper from March 2000. The main industrial stake holders all had the opportunity to comment on the Green Paper and from their directive proposal. Here, we find that the dominant interest groups indeed influenced the final design of an EU GHG market. This industrial rent-seeking most prominently lead to a grand fathered permit allocation rule like the one found in the US tradable permit systems. (au)

Nuclear energy of the light elements deuterium and lithium can be released if the 100 MK degree temperature required for deuterium-tritium thermonuclear fusion reactions can be achieved together with sufficient thermal insulation for a net energy yield. Progress of world-wide research shows good prospect for these physical conditions being achieved by the use of magnetic field confinement and of rapidly developing heating methods. Tokamak systems, alternative magnetic systems and inertial confinement progress are described. International co-operation features a number of bilateral agreements between countries: the Euratom collaboration which includes the Joint European Torus, a joint undertaking of eleven Western European nations of Euratom, established to build and operate a major confinement experiment; the development of co-operative projects within the OECD/IEA framework; the INTOR workshop, a world-wide study under IAEA auspices of the next major step in fusion research which might be built co-operatively; and assessments of the potential of nuclear fusion by the IAEA and the International Fusion Research Council. The INTOR (International Tokamak Reactor) studies have outlined a major plant of the tokamak type to study the engineering and technology of fusion reactor systems, which might be constructed on a world-wide basis to tackle and share the investment risks of the developments which lie ahead. This paper summarizes the recent progress of research on controlled nuclear fusion, featuring those areas where international co-operation has played an important part, and describes the various arrangements by which this international co-operation is facilitated.

Full Text Available This study presents trends and projected estimates of methane and nitrous oxide emissions from livestock of India vis-à-vis world and developing countries over the period 1961 to 2010 estimated based on IPCC guidelines. World enteric methane emission (EME increased by 54.3% (61.5 to 94.9 ×109 kg annually from the year 1961 to 2010, and the highest annual growth rate (AGR was noted for goat (2.0%, followed by buffalo (1.57% and swine (1.53%. Global EME is projected to increase to 120×109 kg by 2050. The percentage increase in EME by Indian livestock was greater than world livestock (70.6% vs 54.3% between the years 1961 to 2010, and AGR was highest for goat (1.91%, followed by buffalo (1.55%, swine (1.28%, sheep (1.25% and cattle (0.70%. In India, total EME was projected to grow by 18.8×109 kg in 2050. Global methane emission from manure (MEM increased from 6.81 ×109 kg in 1961 to 11.4×109 kg in 2010 (an increase of 67.6%, and is projected to grow to 15×109 kg by 2050. In India, the annual MEM increased from 0.52×109 kg to 1.1×109 kg (with an AGR of 1.57% in this period, which could increase to 1.54×109 kg in 2050. Nitrous oxide emission from manure in India could be 21.4×106 kg in 2050 from 15.3×106 kg in 2010. The AGR of global GHG emissions changed a small extent (only 0.11% from developed countries, but increased drastically (1.23% for developing countries between the periods of 1961 to 2010. Major contributions to world GHG came from cattle (79.3%, swine (9.57% and sheep (7.40%, and for developing countries from cattle (68.3%, buffalo (13.7% and goat (5.4%. The increase of GHG emissions by Indian livestock was less (74% vs 82% over the period of 1961 to 2010 than the developing countries. With this trend, world GHG emissions could reach 3,520×109 kg CO2-eq by 2050 due to animal population growth driven by increased demands for meat and dairy products in the world.

It will be difficult to gain the agreement of all the actors on any proposal for climate change management, if universality and fairness are not considered. In this work, a universal measure of emissions to be applied at the international level is proposed, based on a modification of the Greenhouse Gas Intensity (GHG-INT) measure. It is hoped that the generality and low administrative cost of this measure, which we call the Modified Greenhouse Gas Intensity measure (MGHG-INT), will eliminate any need to classify nations. The core of the MGHG-INT is what we call the IHDI-adjusted Gross Domestic Product (IDHIGDP), based on the Inequality-adjusted Human Development Index (IHDI). The IDHIGDP makes it possible to propose universal measures, such as MGHG-INT. We also propose a carbon border tax applicable at national borders, based on MGHG-INT and IDHIGDP. This carbon tax is supported by a proposed global Emissions Trading System (ETS). The proposed carbon tax is analyzed in a short-term scenario, where it is shown that it can result in a significant reduction in global emissions while keeping the economy growing at a positive rate. In addition to annual GHG emissions, cumulative GHG emissions over two decades are considered with almost the same results. - Highlights: ► An IHDI-adjusted GDP (IHDIGDP) is introduced to universally account the activities of nations. ► A modified GHG emission intensity (MGHG-INT) is introduced based on the IHDIGDP. ► Based on green and red scenarios, admissible emissions and RED percentage are introduced. ► The RED percentage is used to define a border carbon tax (BCT) and emission trading system. ► The MGHG-INT can provide a universal control on emissions while allowing high economical growth

The water-food-energy-GHG nexus under climate change has been gaining increasing attention from both the research and policy communities, especially over the past several years. However, most existing nexus studies are qualitative and explorative in nature. So far, very few studies provide integrated analysis of this nexus across all the four sectors. The purpose of this paper is to examine this nexus by assessing the effects of climate change on agricultural production through the change in water availability, evaluating the adjustment responses and resulting energy consumption and GHG emission, with the Northeast China as a case study. Based on our simulation results, by 2030, climate change is projected to increase water supply and demand gap for irrigation in Northeast China. Due to the increase in water scarcity, irrigated areas will decrease, and the cropping pattern will be adjusted by increasing maize sown areas and decreasing rice sown areas. As a result, the total output of crops and profits will clearly be reduced. Finally, energy consumption and GHG emission from irrigation will be reduced. This study suggests that climate change impact assessment fully consider the nexus among water, food, energy and GHG; however, more studies need to be conducted in the future.

Substitution elasticities between GHG-polluting and nonpolluting inputs in agricultural production: A meta-regression

2016-01-01

This paper reports meta-regressions of substitution elasticities between greenhouse gas (GHG) polluting and nonpolluting inputs in agricultural production, which is the main feedstock source for biofuel in the U.S. We treat energy, fertilizer, and manure collectively as the “polluting input” and labor, land, and capital as nonpolluting inputs. We estimate meta-regressions for samples of Morishima substitution elasticities for labor, land, and capital vs. the polluting input. Much of the heterogeneity of Morishima elasticities can be explained by type of primal or dual function, functional form, type and observational level of data, input categories, number of outputs, type of output, time period, and country categories. Each estimated long-run elasticity for the reference case, which is most relevant for assessing GHG emissions through life-cycle analysis, is greater than 1.0 and significantly different from zero. Most predicted long-run elasticities remain significantly different from zero at the data means. These findings imply that life-cycle analysis based on fixed proportion production functions could provide grossly inaccurate measures of GHG of biofuel. - Highlights: • This paper reports meta-regressions of substitution elasticities between greenhouse-gas (GHG) polluting and nonpolluting inputs in agricultural production, which is the main feedstock source for biofuel in the U.S. • We estimate meta-regressions for samples of Morishima substitution elasticities for labor, land, and capital vs. the polluting input based on 65 primary studies. • We found that each estimated long-run elasticity for the reference case, which is most relevant for assessing GHG emissions through life-cycle analysis, is greater than 1.0 and significantly different from zero.

Estimating GHG emission mitigation supply curves of large-scale biomass use on a country level

2007-01-01

This study evaluates the possible influences of a large-scale introduction of biomass material and energy systems and their market volumes on land, material and energy market prices and their feedback to greenhouse gas (GHG) emission mitigation costs. GHG emission mitigation supply curves for large-scale biomass use were compiled using a methodology that combines a bottom-up analysis of biomass applications, biomass cost supply curves and market prices of land, biomaterials and bioenergy carriers. These market prices depend on the scale of biomass use and the market volume of materials and energy carriers and were estimated using own-price elasticities of demand. The methodology was demonstrated for a case study of Poland in the year 2015 applying different scenarios on economic development and trade in Europe. For the key technologies considered, i.e. medium density fibreboard, poly lactic acid, electricity and methanol production, GHG emission mitigation costs increase strongly with the scale of biomass production. Large-scale introduction of biomass use decreases the GHG emission reduction potential at costs below 50 Euro /Mg CO 2eq with about 13-70% depending on the scenario. Biomaterial production accounts for only a small part of this GHG emission reduction potential due to relatively small material markets and the subsequent strong decrease of biomaterial market prices at large scale of production. GHG emission mitigation costs depend strongly on biomass supply curves, own-price elasticity of land and market volumes of bioenergy carriers. The analysis shows that these influences should be taken into account for developing biomass implementations strategies

This paper describes an international nursing and health research immersion program. Minority students from the USA work with an international faculty mentor in teams conducting collaborative research. The Minority Health International Research Training (MHIRT) program students become catalysts in the conduct of cross-cultural research. To narrow the healthcare gap for disadvantaged families in the USA and partner countries. Faculty from the USA, Germany, Italy, Colombia, England, Austria and Thailand formed an international research and education team to explore and compare family health issues, disparities in chronic illness care, social inequities and healthcare solutions. USA students in the MHIRT program complete two introductory courses followed by a 3-month research practicum in a partner country guided by faculty mentors abroad. The overall program development, student study abroad preparation, research project activities, cultural learning, and student and faculty team outcomes are explored. Cross-fertilization of research, cultural awareness and ideas about improving family health occur through education, international exchange and research immersion. Faculty research and international team collaboration provide opportunities for learning about research, health disparities, cultural influences and healthcare systems. The students are catalysts in the research effort, the dissemination of research findings and other educational endeavours. Five steps of the collaborative activities lead to programmatic success. MHIRT scholars bring creativity, enthusiasm, and gain a genuine desire to conduct health research about families with chronic illness. Their cultural learning stimulates career plans that include international research and attention to vulnerable populations. © 2012 The Authors.

Implications of a consumer-based perspective for the estimation of GHG emissions. The illustrative case of Luxembourg

International Nuclear Information System (INIS)

Caro, Dario; Rugani, Benedetto; Pulselli, Federico Maria; Benetto, Enrico

2015-01-01

The Kyoto protocol has established an accounting system for national greenhouse gas (GHG) emissions according to a geographic criterion (producer perspective), such as that proposed by the IPCC guidelines for national GHG inventories. However, the representativeness of this approach is still being debated, because the role of final consumers (consumer perspective) is not considered in the emission allocation system. This paper explores the usefulness of a hybrid analysis, including input–output (IO) and process inventory data, as a complementary tool for estimating and allocating national GHG emissions according to both consumer- and producer-based perspectives. We assess the historical GHG impact profile (from 1995 to 2009) of Luxembourg, which is taken as a case study. The country's net consumption over time is estimated to generate about 28,700 Gg CO 2 e/year on average. Compared to the conventional IPCC inventory, the IO-based framework typically shows much higher emission estimations. This relevant discrepancy is mainly due to the different points of view obtained from the hybrid model, in particular with regard to the contribution of imported goods and services. Detailing the GHG inventory by economic activity and considering a wider system boundary make the hybrid IO method advantageous as compared to the IPCC approach, but its effective implementation is still limited by the relatively complex modeling system, as well as the lack of coordination and scarce availability of datasets at the national level. - Highlights: • GHG emissions for Luxembourg are assessed using hybrid input–output (IO) modeling. • Consumer and producer perspectives are compared for the period 1995–2009. • IO-based GHG profiles are remarkably higher than traditional IPCC inventorying. • IO-based GHG accounting presents some advantages but is limited in implementation. • Key-aspects of IPCC and IO-based methods are extensively investigated and compared

Directory of Open Access Journals (Sweden)

Ghorbanali RASSAM

2015-12-01

Full Text Available The most important issue which has attracted the attention of many scientists is the climate change and global warming due to greenhouse gas emission which has caused the world faced with a great human and environmental disaster. In this study, the amount of greenhouse gas (GHG emissions was estimated in the semi-traditional and semi-mechanized rice production systems in Dargaz region, Iran. All the agricultural and consuming inputs procedures responsible for greenhouse gas emissions were collected and recorded in both systems. The amount of GHG emission in semi-traditional and semi-mechanized was 813.17 and 968.31 kg CO2-eq ha-1, respectively. The fuel consumption with the share of 38.22% in semi-traditional method and 43.32% in semi-mechanized system had the largest share in GHG emission and using Nitrogen fertilizer on farms with the share of 31.97% in semi-traditional method and 26.91% in semi-mechanized system is in the second place of GHG emission. The semi-traditional system had greater GHG emissions in the unit of tone of harvested grain and unit of energy output. The use of alternative methods such as conservation tillage and organic fertilizers can be effective in improving the environmental status of the production area.

GHG emissions quantification at high spatial and temporal resolution at urban scale: the case of the town of Sassari (NW Sardinia - Italy)

Sanna, Laura; Ferrara, Roberto; Zara, Pierpaolo; Duce, Pierpaolo

2014-05-01

The European Union has set as priorities the fight against climate change related to greenhouse gas releases. The largest source of these emissions comes from human activities in urban areas that account for more than 70% of the world's emissions and several local governments intend to support the European strategic policies in understanding which crucial sectors drive GHG emissions in their city. Planning for mitigation actions at the community scale starts with the compilation of a GHG inventories that, among a wide range of measurement tools, provide information on the current status of GHG emissions across a specific jurisdiction. In the framework of a regional project for quantitative estimate of the net exchange of CO2 (emissions and sinks) at the municipal level in Sardinia, the town of Sassari represents a pilot site where a spatial and temporal high resolution GHG emissions inventory is built in line with European and international standard protocols to establish a baseline for tracking emission trends. The specific purpose of this accurate accounting is to obtain an appropriate allocation of CO2 and other GHG emissions at the fine building and hourly scale. The aim is to test the direct measurements needed to enable the construction of future scenarios of these emissions and for assessing possible strategies to reduce their impact. The key element of the methodologies used to construct this GHG emissions inventory is the Global Protocol for Community-Scale Greenhouse Gas Emissions (GPC) (March 2012) that identifies four main types of emission sources: (i) Stationary Units, (ii) Mobile Units, (iii) Waste, and (iv) Industrial Process and Product Use Emissions. The development of the GHG emissions account in Sassari consists in the collection of a range of alternative data sources (primary data, IPCC emission factors, national and local statistic, etc.) selected on the base on relevance and completeness criteria performed for 2010, as baseline year, using

Several different types of links are possible between different GHG-mitigation systems. These include: Linking two or more emission trading schemes so that emissions trading can occur both within and between different schemes ('direct links'); and Linking emission trading systems to registries/mechanisms and systems that generate offsets from project based mechanisms or from direct purchases/transfers of AAUs ('indirect links').

Greenhouse gas emissions from the international maritime transport of New Zealand's imports and exports

Fitzgerald, Warren B.; Howitt, Oliver J.A.; Smith, Inga J.

2011-01-01

Greenhouse gas emissions from international maritime transport are exempt from liabilities under the Kyoto Protocol. Research into quantifying these emissions is ongoing, and influences policy proposals to reduce emissions. This paper presents a cargo-based analysis of fuel consumption and greenhouse gas emissions from New Zealand's international maritime transport of goods. Maritime transport moves 99.5% (by mass) of New Zealand's internationally traded products. It is estimated that 73% of visiting vessels' activity can be directly attributed to the movement of goods in and out of New Zealand. A cargo-based methodology was used to estimate that the international maritime transport of New Zealand's imports and exports consumed 2.5 million tonnes (Mt; 2.6 billion litres) of fuel during the year 2007, which generated 7.7 Mt of carbon dioxide (CO 2 ) emissions. Double-counting of emissions would occur if a similar method was applied to all New Zealand's trading partners. In contrast, since few large vessels refuel in New Zealand, the National Greenhouse Gas Inventory listed 2007 international maritime transportation emissions as 0.98 Mt of CO 2 , calculated from fuel bunkered for international transport. The results, therefore, show a significant difference between activity-based and bunker-fuel methodologies in quantifying New Zealand's emissions. International policy implications are discussed. - Research highlights: → Cargo-based analysis of GHG emissions from New Zealand's international maritime transport of goods. → 7.7 Mt of CO 2 estimated from international maritime transport of NZ's 2007 imports and exports. → 73% of visiting vessels' 2007 activity attributed to the movement of goods in and out of NZ. → The results were significantly different from NZ's GHG Inventory bunker-fuel derived emissions figure. → Detailed approach for international transport emissions regional/national assessments described.

Setting up GHG-based energy efficiency targets in buildings: The Ecolabel

International Nuclear Information System (INIS)

José Vinagre Díaz, Juan; Richard Wilby, Mark; Belén Rodríguez González, Ana

2013-01-01

The European Union has recently updated the regulations for energy performance of buildings and on the certification of energy-related products. The world is in the process of constructing policy frameworks to underwrite carbon emission reduction targets, best exemplified by the Kyoto Protocol. This requires complex technical and economical concepts to be presented in an understandable, transparent, and justifiable format. A building's energy efficiency was traditionally determined based on its annual consumption relative to some average performance level. Emissions are calculated as a derivative of consumptions and their aggregated values allow verification of the level of fulfillment of the objectives. Here we take a different approach: considering that the greenhouse gas emissions (GHG) objectives must be achieved; hence, we fix the efficiency standard based on emissions objectives, and then derive the corresponding reference values of consumption. Accordingly, we propose a certification scheme for energy efficiency in buildings based on targets of GHG emissions levels. This proposed framework includes both a label, namely the Ecolabel, and a fiche showing a set of indices and complementary information. The Ecolabel is designed to provide a flexible, evolvable, simple to use at the point of application, and transparent framework. - Highlights: • In this paper we consider the interaction between greenhouse gas emission reduction targets and building energy efficiency. • Specifically we propose an ‘‘Ecolabel” for buildings that is a GHG emissions liability index, which forms a labeling process. • The label follows the Kyoto Protocol philosophy and translates national GHG targets to targets for each and every building. • The approach provides both a new form of efficiency rating on which emissions reduction policy can be based

Impact of non-petroleum vehicle fuel economy on GHG mitigation potential

Luk, Jason M; Saville, Bradley A; MacLean, Heather L

2016-01-01

The fuel economy of gasoline vehicles will increase to meet 2025 corporate average fuel economy standards (CAFE). However, dedicated compressed natural gas (CNG) and battery electric vehicles (BEV) already exceed future CAFE fuel economy targets because only 15% of non-petroleum energy use is accounted for when determining compliance. This study aims to inform stakeholders about the potential impact of CAFE on life cycle greenhouse gas (GHG) emissions, should non-petroleum fuel vehicles displace increasingly fuel efficient petroleum vehicles. The well-to-wheel GHG emissions of a set of hypothetical model year 2025 light-duty vehicles are estimated. A reference gasoline vehicle is designed to meet the 2025 fuel economy target within CAFE, and is compared to a set of dedicated CNG vehicles and BEVs with different fuel economy ratings, but all vehicles meet or exceed the fuel economy target due to the policy’s dedicated non-petroleum fuel vehicle incentives. Ownership costs and BEV driving ranges are estimated to provide context, as these can influence automaker and consumer decisions. The results show that CNG vehicles that have lower ownership costs than gasoline vehicles and BEVs with long distance driving ranges can exceed the 2025 CAFE fuel economy target. However, this could lead to lower efficiency CNG vehicles and heavier BEVs that have higher well-to-wheel GHG emissions than gasoline vehicles on a per km basis, even if the non-petroleum energy source is less carbon intensive on an energy equivalent basis. These changes could influence the effectiveness of low carbon fuel standards and are not precluded by the light-duty vehicle GHG emissions standards, which regulate tailpipe but not fuel production emissions.

This study examines the evolution of the field of international business (IB) research based on a relational cluster analysis of co-citations in the Journal of International Business Studies (JIBS) from 1982 to 2011. Particularly, we examine the changing role of theory in relation to empirical IB...... research. Based on a factor and network analysis, we identify distinct clusters of IB research and their relations over time. We show that the initial focus of IB research on issues of international expansion has shifted towards issues of governance and implementation. In this process, debates on foreign...... entry mode and culture have served as important integrating themes. At the same time, theory debates in IB have expanded from a narrow focus on explaining international expansion, to a rather heterogeneous conglomerate of approaches which have assisted increasingly differentiated empirical research.

Programs and measures to reduce GHG emissions in agriculture and waste treatment in Slovakia

Energy Technology Data Exchange (ETDEWEB)

Mareckova, K.; Bratislava, S.; Kucirek, S.

1996-12-31

Slovakia is a UN FCCC Annex I country and is obliged to limit its anthropogenic GHG emissions in the year 2000 to 1990 level. The key greenhouse gas in Slovakia is CO{sub 2} resulting mainly from fuel combustion processes. However the share of CH{sub 4} and N{sub 2}O is approximately 20% of the total emissions on GWP basis. These gases are occurring mainly in non-energy sectors. The construction of the non-CO{sub 2} emission scenarios to reduce GHG and the uncertainty in N{sub 2}O and CH{sub 4} emission estimation are discussed focusing on agriculture and waste treatment. The presentation will also include information on emission trends of CH{sub 4} and N{sub 2}O since 1988. There are already implemented measures reducing GHG emissions in Slovakia, however, not motivated by global warming. A short view of implemented measures with an assessment of their benefit concerning non-CO{sub 2} GHG emissions reduction and some proposed mitigation options for agriculture and waste treatment are shown. Expected difficulties connected with preparing scenarios and with implementation of reducing measures are discussed.

Incentives and stability of international climate coalitions: An integrated assessment

Bosetti, Valentina; Carraro, Carlo; De Cian, Enrica; Massetti, Emanuele; Tavoni, Massimo

2013-01-01

This paper analyses the incentives to participate in an international climate agreement and the stability of the resulting climate coalition using the integrated assessment model WITCH. Coalition stability is assessed under alternative assumptions concerning the pure rate of time preference, the aggregation of social welfare, and the severity of climate damages. The profitability, stability, and strong potential internal stability of a number of coalitions, those potentially effective in reducing GHG emissions, is explored in the paper. The main conclusion is that only the grand coalition, i.e. a coalition where all world regions cooperate to reduce emissions, can maintain GHG concentration below 550 ppm CO 2 -eq. However, this coalition is not internally stable, even when allowing for monetary transfers across world regions. Nonetheless, the paper also shows that strongly potentially internally stable coalitions exist, though of smaller size, which can mitigate global warming and limit GHG concentrations to 600 ppm CO 2 -eq. - Highlights: ► We analyse climate coalitions with an integrated assessment model. ► Coalitions’ profitability and stability is analysed under alternative assumptions. ► Effective coalitions should include larger emitters (such as India and China). ► A coalition that achieves 550 ppm CO 2 -eq is not internally stable. ► A stable coalition can achieve around 518 ppme in 2050 and 600 ppme in 2100

The GHG-CCI project (http://www.esa-ghg-cci.org) is one of several projects of ESA's Climate Change Initiative (CCI), which will deliver various Essential Climate Variables (ECVs). The goal of GHG-CCI is to deliver global satellite-derived data sets of the two most important anthropogenic greenhouse gases (GHGs) carbon dioxide (CO2) and methane (CH4) suitable to obtain information on regional CO2 and CH4 surface sources and sinks as needed for better climate prediction. The GHG-CCI core ECV data products are column-averaged mole fractions of CO2 and CH4, XCO2 and XCH4, retrieved from SCIAMACHY on ENVISAT and TANSO on GOSAT. Other satellite instruments will be used to provide constraints in upper layers such as IASI, MIPAS, and ACE-FTS. Which of the advanced algorithms, which are under development, will be the best for a given data product still needs to be determined. For each of the 4 GHG-CCI core data products - XCO2 and XCH4 from SCIAMACHY and GOSAT - several algorithms are being further developed and the corresponding data products are inter-compared to identify which data product is the most appropriate. This includes comparisons with corresponding data products generated elsewhere, most notably with the operational data products of GOSAT generated at NIES and the NASA/ACOS GOSAT XCO2 product. This activity, the so-called "Round Robin exercise", will be performed in the first two years of this project. At the end of the 2 year Round Robin phase (end of August 2012) a decision will be made which of the algorithms performs best. The selected algorithms will be used to generate the first version of the ECV GHG. In the last six months of this 3 year project the resulting data products will be validated and made available to all interested users. In the presentation and overview about this project will be given focussing on the latest results.

Life cycle greenhouse gas (GHG) impacts of a novel process for converting food waste to ethanol and co-products

International Nuclear Information System (INIS)

Ebner, Jacqueline; Babbitt, Callie; Winer, Martin; Hilton, Brian; Williamson, Anahita

2014-01-01

Highlights: • Co-fermentation using SSF at ambient temperature has potential as an ethanol pathway. • Bio-refinery GHG emissions are similar to corn and MSW ethanol production processes. • Net production GHG impact is negative with inclusion of waste disposal avoidance. • Food waste diversion from landfills is the largest contributor to GHG benefits. - Abstract: Waste-to-ethanol conversion is a promising technology to provide renewable transportation fuel while mitigating feedstock risks and land use conflicts. It also has the potential to reduce environmental impacts from waste management such as greenhouse gas (GHG) emissions that contribute to climate change. This paper analyzes the life cycle GHG emissions associated with a novel process for the conversion of food processing waste into ethanol (EtOH) and the co-products of compost and animal feed. Data are based on a pilot plant co-fermenting retail food waste with a sugary industrial wastewater, using a simultaneous saccharification and fermentation (SSF) process at room temperature with a grinding pretreatment. The process produced 295 L EtOH/dry t feedstock. Lifecycle GHG emissions associated with the ethanol production process were 1458 gCO 2 e/L EtOH. When the impact of avoided landfill emissions from diverting food waste to use as feedstock are considered, the process results in net negative GHG emissions and approximately 500% improvement relative to corn ethanol or gasoline production. This finding illustrates how feedstock and alternative waste disposal options have important implications in life cycle GHG results for waste-to-energy pathways

2011-01-01

Highlights: → Using the Sato-Vartia index for the three periods of 1985-1995, 1995-2000, and 2000-2005, the changes in three factors affecting GHG emissions in South Korea were analyzed. → A total emission matrix including both direct and indirect GHG emissions showed plain shape; however, ripple effects were observed in some sectors. → This process is useful in measuring national energy policies. → Several limitations of the Divisia decomposition analysis were pointed out. -- Abstract: Through energy input-output (E-IO) analyses from 1985 to 2005, the changes in three factors affecting GHG emissions in South Korea were analyzed. Based on the E-IO results, the changes in the direct and total (embodied) GHG emissions from the pertinent sectors were decomposed into three factors-the energy consumption effect, the social effect, and the technological effect-using the Sato-Vartia index for the three periods of 1985-1995, 1995-2000, and 2000-2005. The decomposition analysis demonstrated that a total emission matrix including both direct and indirect GHG emissions showed an evolution pattern that was very similar to the changes in direct GHG emissions; however, ripple effects were observed in the case of emissions from sector number -59 (Synthetic resins, synthetic rubber-p). The results showed that national energy policies such as those pertaining to the diversification of energy sources, shifts in the energy consumption structure (social effect), and the transformation to a low-carbon energy economy (technology effect) were effective. Finally, several limitations of the Divisia decomposition analysis were pointed out.

National Framework for GHG Emission Trading in Russia

Kotov, V.; Nikitina, E.

2003-01-01

If Russia ratifies the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC), domestic implementation of its international commitments under this international regime will require special national responses, i.e. institutional capacity building for application of its mechanisms. The Kyoto Protocol and its mechanisms, particularly, international emission trading (IET) and joint implementation (JI), mark a turning point, with opportunities for Russia to benefit from an economic and environmental standpoint from international cooperation. Russia might wish to sell to other parties a surplus in its assigned amount for the first commitment period in 2008-2012, as according to existing estimates its GHG emissions are expected to be below their 1990 base level. In order to participate in international emission trading, Russia has to meet several international requirements, including providing national inventory and reporting and establishing national registry compatible with the standard international format. It is to establish a domestic institutional regime defining laws and rules of behaviour for its participants, the administrative frameworks, and designing major schemes for domestic emission trading programme. Russia's emission trading system is not formed yet. This is a challenging innovation for Russia, as in its previous environmental management practices it did not have any experience in domestic emission trading with other air pollutants. The paper examines the key elements suggested in a number of existing proposals, assessments, and approaches of the government, parliamentarians and non-governmental experts for its institutional design which is at the core of ongoing climate policy debates in the country. These approaches and practical suggestions define the current state-of-the-art in domestic emission trading regime formation and channel the paths of its institutional development in the future. This paper analyses peculiarities

A Study on Portfolio of Domestic Policies and Measures for GHG emission Abatement

Energy Technology Data Exchange (ETDEWEB)

Lim, J.K. [Korea Energy Economics Institute, Euiwang (Korea)

2001-11-01

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.

Assessment of mitigation pathways of GHG emissions from the Korean waste sector through 2050

Directory of Open Access Journals (Sweden)

Yongjoo Chung

2018-05-01

Full Text Available The waste sector may play a significant role in national mitigation policies with further greenhouse gas (GHG reduction opportunities mainly because of its linkage to other sectors. However, the waste sector has not drawn much attention from research community mainly because the amount of GHG emissions from the waste sector is notably smaller than other sectors. This study presents emissions estimation and mitigation potentials of the waste sector in Korea. Emission estimates and business-as-usual emissions through 2050 are estimated based on four different treatment methods, including landfill, incineration, wastewater, and biological treatment by considering country-specific emission parameters of wastes, where available. Different types of wastes for each treatment method are investigated to obtain accurate emission estimates. It is expected that GHG emissions in 2050 are about 12.0 Tg CO2eq, which is 17% less than those in 2010. Mitigation potentials and economic impacts of five different measures are also investigated, and it is revealed that the production of refuse drive fuel from combustible municipal solid wastes may render the greatest benefit with the most mitigation potential of 649 kt CO2eq. An interdependent nature among mitigation measures is further discussed and it is shown that, if implemented together, the accumulated mitigation potentials are far less than the simple sum of individual potentials. It is implied that an aggregate potential of individual measures needs to be examined when implementing several mitigation measures simultaneously. This study outlines how to investigate emissions estimation and mitigation pathways for the waste sector in a national level.

A national inventory of greenhouse gas (GHG), criteria air contaminants (CAC) and hydrogen sulphide (H2S) emissions by the upstream oil and gas industry : volume 1, overview of the GHG emissions inventory : technical report

International Nuclear Information System (INIS)

2004-09-01

A detailed inventory of greenhouse gas (GHG) emissions from the upstream oil and gas sector in Canada was presented along with explanations of the methodologies and data sources used. This report is based on previous work done on methane and volatile organic compound emissions from the upstream oil and gas sector for the period of 1990 to 1995, but it includes key improvements in identifying primary types of emissions sources such as emissions from fuel combustion, flaring, venting, fugitive equipment leaks and accidental releases. It also includes criteria air contaminants and hydrogen sulfide emissions, an analysis of GHG emission intensities and a change in the definition of volatile organic compounds from comprising all non-methane hydrocarbons to comprising all non-methane and non-ethane hydrocarbons. The report covers portions of the upstream oil and gas industry in Canada plus the natural gas transmission and natural gas distribution industries with reference to well drilling, oil production, and natural gas production, processing, transmission and distribution. Accidents and equipment failures are also included. The report reveals the total GHG emissions by source type, sub-sector, facility type and sub-type for the year 2000 at the national level. In 2000, the total carbon dioxide equivalent GHG emissions from the entire oil and gas sector were 101,211 kilo tonnes. For the upstream oil and gas sector alone, total GHG emissions were 84,355 kilo tonnes, representing 12 per cent of Canada's total national emissions of GHGs in 2000. This is an increase of about 25 per cent from 1995 levels. The biggest primary source of these emissions is fuel combustion, which accounts for 40.8 per cent of the total. This report also includes a provincial breakdown of GHG emissions for the natural gas transmission, storage and distribution sub-sectors in Canada for the year 2000. refs., tabs., figs

Reducing GHG emissions in agricultural production process for production of biofuels by growing legumes and production-technical measures

International Nuclear Information System (INIS)

Gurgel, Andreas; Schiemenz, Katja

2017-01-01

The reduction of greenhouse gases (GHG) emissions in the supply chain for biofuels is a big challenge especially for the German and European cultivation of energy crops. The production of nitrogen fertilizers and field emissions are the main factors of GHG emissions. The amount of field emissions depends very strongly on the nitrogen effort and the intensity of tillage. The main objective is to reduce GHG emissions in field cropping systems within the biofuel production chains. An inclusion of legumes into crop rotations is particularly important because their cultivation does not require nitrogen fertilizer. Data base for the project is a complex field experiment with the biofuel crops winter rape and winter wheat. Previous crops are winter wheat, peas and lupins. ln each case tilling systems are compared with non-tilling. The first results of the field experiments are nitrogen functions depending on previous crops, sites and tilling system. Calculation models for GHG reduction models were developed on the bases of these results. By growing legumes as previous crops before wheat and rape it is possible to reduce GHG emissions from 2 to 10 g CO_2_e_q per MJ. The best reduction of GHG emissions is possible by combining legumes as previous crops with a reduced nitrogen effort.

Summary report on GHG emission markets. Experiences and projects. Version from December 18, 2000, completed with the update from January 27, 2003

2003-01-01

This document provides a brief and succinct overview of all the initiatives taken by governments, parliaments and industry in a number of countries to examine or establish systems for trading greenhouse gas (GHG) emissions. It is intended chiefly for non-specialists (details of the precise mechanisms at work in each system have been purposely omitted in order to emphasize only the fundamental principles adopted in each case). We note a remarkable trend (especially in the English speaking world) in preparing such systems, which are felt to be an effective way of reducing companies' GHG emissions. France will need to adopt a much more proactive approach in this area if it wants to play any role in defining the future international system and if its industry and authorities are to be ready to take part in it. This document is based in part on a much more detailed report by the NHO (Federation of Norwegian Companies) and on the MIES/Industry document entitled 'Implementing an emission credits trading system in France to optimise industry's contribution to reducing greenhouse gases'. Having proven its ability to meet an environmental objective at a low cost, the system consisting of setting targets and trading emissions is now widely recognized as being the most effective tool for tackling the problem of how to reduce greenhouse gas emissions in the manufacturing sector. The last three years have witnessed an intense process of research, preparation, simulation and real life experimentation, chiefly in the UK, North America, Europe, the Nordic countries, Australia,... Simulations has shown just how easy it is to implement such a system, the speed with which those involved can learn to master the tool, and the market's effectiveness in encouraging actors to make the necessary investment once has been established a long-term vision of the objectives to be achieved in a system of unchanging rules. Real life experience has shown that by setting a

BC Hydro shops for GHG offsets

International Nuclear Information System (INIS)

Anon.

2000-01-01

BC Hydro is reported to have offered to purchase one million tonnes of carbon dioxide reductions in Canada's Greenhouse Gas Emissions Reduction Trading program (GERT). The program uses a baseline and credit system, where emitters purchase measurable quantities of site-specific GHG reductions. Since mid-1998, the program registered five bilateral trades and seven offers to sell. BC Hydro's recent offer is the first offer to buy. BC Hydro has made the offer to buy in expectation of the introduction of the start of the Kyoto Protocol reductions, and expects to be in the game for some time to come if it is to meet its obligations under the Kyoto Protocol. Preference will be given to projects located in Canada, but BC Hydro will consider reductions created anywhere in the world. The financial range of a single trade is between $50,000 and $1 million. (GHG offsets are currently trading in North America for between $.50 and $3.00 Cdn per metric tonne of carbon dioxide equivalent.) At present, offsets are selling at a heavily discounted price because of the uncertainty that investments made now will be credited against future regulations curbing emitters. Consequently, buying now while prices are low, may lead to sizable benefits later, depending on the actual regulations when they are promulgated. Trading now will also give BC Hydro greater credibility and assurance to have its voice heard when discussions about emissions trading and the implementation of emission trading rules reaches the serious stage

Highlights: • This study advances an integrated MSW management model under inexact input information. • The model can minimize net system cost and mitigate GHG emissions. • The model is particularly developed for the city of Beijing, China. • It reduces system cost by [45, 61]% and mitigates GHG emissions by [141, 179]%. • It could provide implications to megacities regarding GHG emissions control. - Abstract: This study advances an integrated MSW management model under inexact input information for the city of Beijing, China. The model is capable of simultaneously generating MSW management policies, performing GHG emission control, and addressing system uncertainty. Results suggest that: (1) a management strategy with minimal system cost can be obtained even when suspension of certain facilities becomes unavoidable through specific increments of the remaining ones; (2) expansion of facilities depends only on actual needs, rather than enabling the full usage of existing facilities, although it may prove to be a costly proposition; (3) adjustment of waste-stream diversion ratio directly leads to a change in GHG emissions from different disposal facilities. Results are also obtained from the comparison of the model with a conventional one without GHG emissions consideration. It is indicated that (1) the model would reduce the net system cost by [45, 61]% (i.e., [3173, 3520] million dollars) and mitigate GHG emissions by [141, 179]% (i.e., [76, 81] million tons); (2) increased waste would be diverted to integrated waste management facilities to prevent overmuch CH{sub 4} emission from the landfills.

Song, Junnian; Yang, Wei; Higano, Yoshiro; Wang, Xian’en

2015-01-01

Highlights: • Renewable energy development is expanded and introduced into socioeconomic activities. • A dynamic optimization simulation model is developed based on input–output approach. • Regional economic, energy and environmental impacts are assessed dynamically. • Industrial and energy structure is adjusted optimally for GHG emission reduction. - Abstract: Specifying the renewable energy development as new energy industries to be newly introduced into current socioeconomic activities, this study develops a dynamic simulation model with input–output approach to make comprehensive assessment of the impacts on economic development, energy consumption and GHG emission under distinct levels of GHG emission constraints involving targeted GHG emission reduction policies (ERPs) and industrial restructuring. The model is applied to Jilin City to conduct 16 terms of dynamic simulation work with GRP as objective function subject to mass, value and energy balances aided by the extended input–output table with renewable energy industries introduced. Simulation results indicate that achievement of GHG emission reduction target is contributed by renewable energy industries, ERPs and industrial restructuring collectively, which reshape the terminal energy consumption structure with a larger proportion of renewable energy. Wind power, hydropower and biomass combustion power industries account for more in the power generation structure implying better industrial prospects. Mining, chemical, petroleum processing, non-metal, metal and thermal power industries are major targets for industrial restructuring. This method is crucial for understanding the role of renewable energy development in GHG mitigation efforts and other energy-related planning settings, allowing to explore the optimal level for relationships among all socioeconomic activities and facilitate to simultaneous pursuit of economic development, energy utilization and environmental preservation

2016-01-01

Highlights: • A life cycle assessment is conducted on the microgrids for an industry application. • The effect of renewable energy on the LCA performances of microgrids is illustrated. • The minimal life cycle energy use and GHG emissions of microgrids are evaluated. • The LCA of different pathways for electricity, heat and hydrogen are presented. - Abstract: Microgrids provide a new energy paradigm with the benefits of higher energy supply reliability, lower greenhouse gas (GHG) emissions through a higher penetration of renewable sources, higher energy efficiencies through the use of local waste heat and the avoidance of losses in transmission and distribution. This study reports a life cycle assessment (LCA) of microgrids for an industry application of an ammonia plant in central Inner Mongolia, China. The life cycle energy use and GHG emissions of the microgrids are evaluated and compared to the existing fossil fuel-based energy system. The electricity, heat and hydrogen fuel loads of the ammonia plant are all modelled in the study. An optimization model is developed to estimate the minimum life cycle energy use and GHG emissions with the microgrids under three scenarios (natural gas (NG)-based, optimized, and maximum renewable energy microgrids). The results indicate that the use of wind and solar in the NG-based microgrid can only slightly reduce the energy use and GHG emissions. If there are no land area limitations on the deployment of solar and wind power, the maximum renewable energy microgrid offers significant reductions of fossil fuel energy of up to 56.9% and GHG emissions reductions of up to 66.3% compared to the existing energy system.

Comparative evaluation of GHG emissions from the use of Miscanthus for bio-hydrocarbon production via fast pyrolysis and bio-oil upgrading

International Nuclear Information System (INIS)

Shemfe, Mobolaji B.; Whittaker, Carly; Gu, Sai; Fidalgo, Beatriz

2016-01-01

Highlights: • GHG emissions from the upgrading of pyrolysis-derived bio-oil is quantified.. • Soil organic carbon sequestration rate had a significant effect on GHG emission. • Increasing plant scale could improve the environmental performance of the system. • Nitrogen to the pyrolysis reactor had significant impact on GHG emissions. - Abstract: This study examines the GHG emissions associated with producing bio-hydrocarbons via fast pyrolysis of Miscanthus. The feedstock is then upgraded to bio-oil products via hydroprocessing and zeolite cracking. Inventory data for this study were obtained from current commercial cultivation practices of Miscanthus in the UK and state-of-the-art process models developed in Aspen Plus®. The system boundary considered spans from the cultivation of Miscanthus to conversion of the pyrolysis-derived bio-oil into bio-hydrocarbons up to the refinery gate. The Miscanthus cultivation subsystem considers three scenarios for soil organic carbon (SOC) sequestration rates. These were assumed as follows: (i) excluding (SOC), (ii) low SOC and (iii) high (SOC) for best and worst cases. Overall, Miscanthus cultivation contributed moderate to negative values to GHG emissions, from analysis of excluding SOC to high SOC scenarios. Furthermore, the rate of SOC in the Miscanthus cultivation subsystem has significant effects on total GHG emissions. Where SOC is excluded, the fast pyrolysis subsystem shows the highest positive contribution to GHG emissions, while the credit for exported electricity was the main ‘negative’ GHG emission contributor for both upgrading pathways. Comparison between the bio-hydrocarbons produced from the two upgrading routes and fossil fuels indicates GHG emission savings between 68% and 87%. Sensitivity analysis reveals that bio-hydrocarbon yield and nitrogen gas feed to the fast pyrolysis reactor are the main parameters that influence the total GHG emissions for both pathways.

GHG emissions due to deforestation

International Nuclear Information System (INIS)

Croezen, H.; Van Valkengoed, M.

2009-05-01

An assessment was made for the magnitude of greenhouse gas emissions resulting from deforestation and forest degradation in tropical forests in Malaysia and Indonesia related to Dutch economic activities. Greenhouse gas emissions (GHG) are calculated in relation to (1) the emissions related to vegetation removal sec; and (2) the emissions related to removal and more long term effects related to assimilation of CO2 in forest regrowth and changes in organic material in soils. Emissions related to vegetation removal and aggregated emissions for both vegetation removal and long term effects are reported separately. Soil organic carbon stock changes are considered by Greenpeace as more uncertain, so the emphasis will be on the direct emissions. Changes in carbon stocks and N2O emissions and actually also changes in vegetation all are events that occur gradually, rather than immediately. Only removal of existing vegetation and possible burning of this vegetation and associated emissions related to both activities are immediate by nature. Carbon stocks and N2O emissions change to a new level within several decades after deforestation or forest degradation. Removed vegetation can grow back or be replaced eventually by other vegetation, thereby changing the net greenhouse gas (GHG) emissions related to deforestation or forest degradation. Vegetation extracted for commercial purposes such as timber or pulp will also take years or decades to become waste and be converted into CO2. In IPCC and LCA's all these emissions are taken into account - or at least all emissions occurring within a period of 20 years, as required by IPCC. Soil organic carbon stock changes are also considered by Greenpeace as more uncertain, so the emphasis will be on the direct emmissions.

Reduction potentials of energy demand and GHG emissions in China's road transport sector

International Nuclear Information System (INIS)

Yan Xiaoyu; Crookes, Roy J.

2009-01-01

Rapid growth of road vehicles, private vehicles in particular, has resulted in continuing growth in China's oil demand and imports, which has been widely accepted as a major factor effecting future oil availability and prices, and a major contributor to China's GHG emission increase. This paper is intended to analyze the future trends of energy demand and GHG emissions in China's road transport sector and to assess the effectiveness of possible reduction measures. A detailed model has been developed to derive a reliable historical trend of energy demand and GHG emissions in China's road transport sector between 2000 and 2005 and to project future trends. Two scenarios have been designed to describe the future strategies relating to the development of China's road transport sector. The 'Business as Usual' scenario is used as a baseline reference scenario, in which the government is assumed to do nothing to influence the long-term trends of road transport energy demand. The 'Best Case' scenario is considered to be the most optimized case where a series of available reduction measures such as private vehicle control, fuel economy regulation, promoting diesel and gas vehicles, fuel tax and biofuel promotion, are assumed to be implemented. Energy demand and GHG emissions in China's road transport sector up to 2030 are estimated in these two scenarios. The total reduction potentials in the 'Best Case' scenario and the relative reduction potentials of each measure have been estimated

Occupational therapy is a global profession represented by the World Federation of Occupational Therapists (WFOT). International research priorities are needed for strategic guidance on global occupational therapy practice. The objective of this study was to develop international research priorities to reflect global occupational therapy practice. A Delphi study using three rounds of electronic surveys, distributed to WFOT member organizations and WFOT accredited universities, was conducted. Data were analyzed after each round, and priorities were presented for rating and ranking in order of importance. Forty-six (53%) out of 87 WFOT member countries participated in the Delphi process. Eight research priorities were confirmed by the final electronic survey round. Differences were observed in rankings given by member organizations and university respondents. Despite attrition at Round 3, the final research priorities will help to focus research efforts in occupational therapy globally. Follow-up research is needed to determine how the research priorities are being adopted internationally.

Macro economic linkages and impacts. Technical and fiscal options in GHG abatement

International Nuclear Information System (INIS)

Backus, G.; Barker, T.

1995-01-01

This paper discusses some of the main macro economic linkages and feedbacks associated with policies for GHG abatement. The linkages in a global model are described when OECD carbon taxes or alternatively OECD/OPEC joint action raises world oil prices with a smaller OECD carbon tax. The results give a world perspective on the GHG abatement problem. The paper continues with a discussion of the linkages and feedbacks associated with three options: demand-side management (DSM), mainly to improve end-use energy efficiency, reductions in subsidies of fossil fuel production and use, and investment in renewable energy supplies, specifically in energy forestry and associated infrastructure. It concludes that DSM and investment in renewables are unlikely on their own to bring about reduction in GHG emissions, and that new supplies may even lead to increased emissions by driving down the price of energy. However, reductions in emissions may be compatible with increased efficiency and development, as well as with improvements in the quality of the local environment and in rural living, with the new supplies replacing fossil fuel supplies, provided that real fossil fuel prices are increased via removal of subsidies and if required carbon taxes.

To verify the optimal aeration interval for oxygen supply and consumption and investigate the effect of aeration interval on GHG emission, reactor-scale composting was conducted with different aeration intervals (0, 10, 30 and 50 min). Although O 2 was sufficiently supplied during aeration period, it could be consumed to  0.902), suggesting that lengthening the duration of aeration interval to some extent could effectively reduce GHG emission.

How to determine the GHG budget of a pasture field with grazing animals

Science.gov (United States)

Ammann, Christof; Neftel, Albrecht; Felber, Raphael

2016-04-01

Up to now the scientific investigation and description of the agriculture related greenhouse gas (GHG) exchange has been largely separated into (i) direct animal related and (ii) ecosystem area related processes and measurement methods. An overlap of the two usually separated topics occurs for grazed pastures, where direct animal and pasture area emissions are relevant. In the present study eddy covariance (EC) flux measurements on the field scale were combined with a source location attribution (footprint) model and with GPS position measurements of the individual animals. The experiment was performed on a pasture field in Switzerland under a rotational full grazing regime with dairy cows. The exchange fluxes of CH4, CO2, and N2O were measured simultaneously over the entire year. The observed CH4 emission fluxes correlated well with the presence of cows in the flux footprint. When converted to average emission per cow, the results agreed with published values from respiration chamber experiments with similar cows. For CO2 a sophisticated partitioning algorithm was applied to separate the pasture and animal contributions, because both were in the same order of magnitude. The N2O exchange fully attributable to the pasture soil showed considerable and continuous emissions through the entire seasonal course mainly modulated by soil moisture and temperature. The resulting GHG budget shows that the largest GHG effect of the pasture system was due to enteric CH4 emissions followed by soil N2O emissions, but that the carbon storage change was affected by a much larger uncertainty. The results demonstrate that the EC technique in combination with animal position information allows to consistently quantify the exchange of all three GHG on the pasture and to adequately distinguish between direct animal and diffuse area sources (and sinks). Yet questions concerning a standardized attribution of animal related emissions to the pasture GHG budget still need to be resolved.

The Directive 2009/28/EG (RED) requires a minimum level of greenhouse gas reduction for biofuels to be marketed. Site-specific production conditions are not considered in default values, which are specified by RED for calculating the greenhouse gas emissions. However, calculations of regional and farm specific GHG balances in accordance to the method of ExpRessBio for the production of rape seed show a considerable range of GHG-emissions in CO{sup 2}-eq (25.2-43.6 g MJ{sup -1}). For the complete product system of decentralized rapeseed oil fuel production in Bavaria a GHG reduction of 58 % can be achieved. This is slightly higher than the default value of 57 % as specified in Directive 2009/28/EG. The reason for this is that the default value under Directive 2009/28/EG is based on an industrial oil production process whereas decentralized production leads to less GHG emissions. In comparison to the application of the energy allocation method the substitution method for the assessment of rape seed cake as protein feed leads to a distinct higher GHG reduction rate of 85%.

It is crucial to determine energy efficiency and environmental effects of greenhouse productions. Such study can be a viable solution in probing challenges and existing defects. The aims of this study were to analyze energy consumption and greenhouse gas (GHG) emissions for pepper production using biological method inside greenhouses which used natural gas (NG) heating system in Esfahan province. Data were collected from 22 greenhouse holders using a face to face questionnaire method, in 2010-2011. Also, functional area was selected 1000 m2. Total energy input, total energy output, energy ratio, energy productivity, specific energy, net energy gain and total GHG emissions were calculated as 297799.9 MJ area-1, 3851.84 MJ area-1, 0.013, 0.016 kg MJ-1, 61.85 MJ kg-1, -293948 MJ area-1 and 14390.85 kg CO2 equivalent area-1, respectively. Result revealed that replacing diesel fuel with NG will not be an effective way of reducing energy consumption for greenhouse production. However, it is crucial to focus on energy management in order to enhance the energy and environmental indices. One way to supply adequate input energy and a reduction in GHG emissions is the utilization of renewable and clean energy sources instead of NG and diesel fuel. Also, it is suggested to adopt solar greenhouses in the region and to supply electricity from non-fossil sources seriously.

Pakistan - Nuclear power for GHG mitigation and sustainable energy development

2000-01-01

Although Pakistan's contribution to global GHG emissions is very small (currently only 0.3% of world-wide emissions), it shares with the world community the concerns of climate change due to the build-up of GHGs. Pakistan is committed to co-operating with global efforts to avert the potential threat of global warming and is already working towards its own socio-economic development in a sustainable manner. However, due to the country's limited technical and financial capabilities, its efforts are diluted and limited to only high priority areas of national interest. There is a large potential for expanding these efforts, if the necessary technical and financial support can be made available, and such an expansion would contribute significantly to the collective global objective of sustainable development. One such step is the reduction of GHG emissions from Pakistan's power sector by introducing advanced cleaner technologies. Nuclear power is one such technology

Asia bears more than half the global tuberculosis (TB) burden. Economic development in the region has increased available funding for biomedical research and opportunity for collaboration. We explored the extent of international tuberculosis research collaborations between institutions within Asia. We conducted a Pubmed search for all articles with tuberculosis in the title published during a 12 month period with at least one author affiliation listed in Asia, then identified international collaborations from institution websites and internet searches. We identified 99 international collaborations involving an institution within Asia, of which only 8 (8.1%) were collaborations between Asian institutions. The remainder were with institutions outside of Asia. The paucity of intra-Asian international research collaboration represents a lost opportunity to optimise regional research funding, capacity building and the development of an Asia-relevant TB research agenda.

High-tech and climate change : promoting the application of enabling and high-tech solutions to reduce GHG emissions : final report

International Nuclear Information System (INIS)

2003-03-01

This report identifies the greenhouse gas (GHG) reducing potential of the high-tech sector with particular reference to the following 5 key technology convergence groups: biotechnology and bio-products; intelligent systems; information and communications technology; advanced materials; and, nanotechnology. It was noted that Canada's efforts to reduce GHG emissions in the abatement of climate change can drive innovation, stimulate economic growth and attain international leadership in technology solutions. Although Canada's strong economic growth has resulted in the creation of more highly skilled jobs, expansion in innovation and new infrastructure, there is a challenge of preserving the environmental and social quality within communities, and ensuring that productivity within companies does not lapse. In response, the government is shaping policy responses that drive innovation, productivity and prosperity and which help Canadian companies capitalize on emerging global opportunities while minimizing environmental and social impacts. This report includes information on climate change and the Kyoto Protocol, Canada's Climate Change Action Plan and the emerging carbon marketplace. It also describes the role of technology innovation and the opportunity of convergence in spurring innovation. Several actions have been proposed to Industry Canada by different technology sectors to help climate change providers generate innovative solutions, commercialize products and expand market presence. This report includes those initiatives which further promote the convergence, growth and development of different enabling and high-tech sectors to develop climate change solutions; promote the opportunities that are emerging to apply innovative high-tech and enabling technologies to reduce GHG emissions; and help Canada meet its Kyoto commitments. 50 refs., 1 tab., 2 figs

Alternative U.S. biofuel mandates and global GHG emissions: The role of land use change, crop management and yield growth

We investigate the impacts of the U.S. renewable fuel standard (RFS2) and several alternative biofuel policy designs on global GHG emissions from land use change and agriculture over the 2010–2030 horizon. Analysis of the scenarios relies on GLOBIOM, a global, multi-sectoral economic model based on a detailed representation of land use. Our results reveal that RFS2 would substantially increase the portion of agricultural land needed for biofuel feedstock production. U.S. exports of most agricultural products would decrease as long as the biofuel target would increase leading to higher land conversion and nitrogen use globally. In fact, higher levels of the mandate mean lower net emissions within the U.S. but when the emissions from the rest of the world are considered, the US biofuel policy results in almost no change on GHG emissions for the RFS2 level and higher global GHG emissions for higher levels of the mandate or higher share of conventional corn-ethanol in the mandate. Finally, we show that if the projected crop productivity would be lower globally, the imbalance between domestic U.S. GHG savings and additional GHG emissions in the rest of the world would increase, thus deteriorating the net global impact of U.S. biofuel policies. - Highlights: ► We model the impact of the U.S. renewable fuel standard (RFS2). ► RFS2 would require more agricultural land and nitrogen globally. ► Increasing the mandates reduce GHG emissions within the U.S. ► Increasing the mandates increase GHG emissions in the rest of the world. ► Total GHG emissions increase with higher levels of mandate; higher share of corn-ethanol; lower productivity growth

The IAGOS GHG package: a measurement system for continuous airborne observations of CO2, CH4, H2O and CO

A cavity ring-down spectroscopy (CRDS) based measurement system for greenhouse gases was designed, tested, and qualified for deployment on commercial airliners within the IAGOS-ERI (In-service Aircraft for a Global Observing System - European Research Infrastructure) project. The design meets requirements regarding physical dimensions (size, weight), performance (long term stability, low maintenance, robustness, full automation) and safety issues (fire prevention regulations). The system uses components of a commercially available CRDS instrument (G2401-m, Picarro Inc.) integrated in a frame suitable for integration in the avionics bay of the Airbus A-340. The first of the IAGOS GHG packages is scheduled for integration in early 2013. The aim is to have seven systems operational within four years, providing for long-term GHG observations with near-global coverage. To enable robust and automated operation of the IAGOS GHG package over six-month deployment periods, numerous technical issues had to be addressed. An inlet system, designed as virtual impactor to eliminate sampling of larger aerosols, ice particles, and water droplets, and provides additional positive ram-pressure. In combination with a lowered sample flow of 0.1 slpm, this ensures a fully controlled sample pressure in the cavity of 140 torr throughout the aircraft altitude operating range up to 12.5 km without the need of an upstream sampling pump. Furthermore, no sample drying is required, as the simultaneously measured water vapor mole fraction is used to correct for dilution and spectroscopic effects. This also enables the collection of science-quality water vapor measurements throughout the atmosphere. To allow for trace gas measurements to be fully traceable to WMO scales, a two-standard calibration system has been designed and tested that periodically provides calibration gas to the instrument during flight and on ground. A targeted six-month deployment cycle followed by maintenance of the package

2016-01-01

Highlights: • This study performs LCA analysis of sugarcane-based bioethanol production. • Energy and GHG balances are evaluated in the entire production chain. • Sensitivity analysis is performed to identify key influencing parameters. • Efficient cogeneration and biogas recovery enhances energy and climate gains. • Results of LCA studies and issues related to land use change impact are discussed. - Abstract: This study analyses the sustainability of fuel ethanol production from cane molasses in Indonesia. Life cycle assessment (LCA) is performed to evaluate the net emissions (climate change impact) and energy inputs (resource consumption) in the production chain. The lifecycle greenhouse gas (GHG) emissions in the production and use of ethanol are estimated at 29 gCO 2eq per MJ of ethanol produced which is a 67% reduction in comparison to gasoline emissions. Net Energy Value (NEV) and Net Renewable Energy Value (NREV) are −7 MJ/l and 17.7 MJ/l, while the energy yield ratio (ER) is 6.1. Economic allocation is chosen for dividing environmental burdens and resource consumption between sugar (i.e. main product) and molasses (i.e. co-product used for fuel production). Sensitivity analysis of various parameters is performed. The emissions and energy values are highly sensitive to sugarcane yield, ethanol yield, and the price of molasses. The use of sugarcane biomass residues (bagasse/trash) for efficient cogeneration, and different waste management options for the treatment of spent wash (effluent of distilleries) are also explored. Surplus bioelectricity generation in the efficient cogeneration plant, biogas recovery from wastewater treatment plant, and their use for fossil fuel substitution can help improve energy and environmental gains. The study also compares important results with other relevant international studies and discusses issues related to land use change (LUC) impact.

The EPA will issue rules regulating greenhouse gas (GHG) emissions from existing steam boilers and refineries in 2012. A crucial issue affecting the scope and cost of emissions reductions will be the potential introduction of flexibility in compliance, including averaging across groups of facilities. This research investigates the role of compliance flexibility for the most important of these source categories—existing coal-fired power plants—that currently account for one-third of national emissions of carbon dioxide, the most important greenhouse gas. We find a flexible standard, calibrated to achieve the same emissions reductions as a traditional(inflexible) approach, reduces the increase in electricity price by 60 percent and overall costs by two-thirds in 2020. The flexible standard also leads to substantially more investment to improve the operating efficiency of existing facilities, whereas the traditional standard leads to substantially greater retirement of existing facilities. - Highlights: ► The U.S. EPA will regulate GHG emissions from power plants under the Clean Air Act. ► We compare a flexible standard with fleet-wide averaging to a traditional standard. ► Flexible standard reduces the increase in electricity price by 60percent in 2020. ► Flexible standard reduces the increase in overall costs by two-thirds in 2020. ► Flexible standard leads to more efficiency investment and less capacity retirement.

An effective consumer-oriented climate policy requires knowing the GHG reduction potential of sustainable consumption. The aim of this study is to draw lessons from differences in consumption between households with high and low GHG emissions. We evaluate a survey of 14,500 households and use a method that allows measuring changes in price level of consumption. Comparing the 10% of households with the highest GHG emissions per capita with the lowest 10% - controlling for differences in expenditure level and household structure - we find a range 5-17 tons of CO{sub 2}-equivalent per capita and year. The observed differences stem mainly from heating, electricity use, car use, and travel by aircraft. Consumption patterns with low GHG emissions are characterized by less spending on mobility, but more on leisure and quality oriented consumption (leading to higher prices per unit). Further characteristics are: a higher share of organic food, low meat consumption and fewer detached single family houses. Our findings imply that a significant reduction in GHG emissions would be possible by adopting real-world consumption patterns observable in society. The twin challenge is to shift consumption towards more climate friendly patterns, and to prevent any trend towards high emitting consumption patterns.

The automobile industry in China has rapidly developed in recent years which resulted in an increase in gasoline usage and greenhouse gas (GHG) emissions. Focus on climate change has also accelerated to grow pressure on reducing vehicle weight and improving fuel efficiency. Aluminum (Al) as a light metal has demonstrated a great potential for weight savings in applications such as engine blocks, cylinder heads, wheels, hoods, tailgates etc. However, primary Al production requires intensive energy and the cost of Al is more than traditional steel, which may affect the total benefits realized from using Al in automobiles. Therefore, it is very essential to conduct a study to quantify the life cycle GHG emissions and energy consumption if the plan is to achieve fleet-wide Al intensive vehicles. This paper describes a life cycle assessment (LCA) methodology and the general modeling assumptions used to evaluate the impact of Al intensive vehicle on GHG emissions and energy consumption. The results indicated that the reductions in life cycle GHG emissions and energy consumption were not significant when the maximum Al content in an automobile is 145 kg, which is the average level of Al usage in automobiles in North America. A neural network methodology was used to forecast the vehicle stock in China from 2010 to 2020 and a vehicle fleet model was established to track GHG emissions and energy consumption of the vehicle fleet. A material availability factor was also introduced into the LCA methodology to further assist decision makers in providing rational proposals for a widespread implementation of Al in automobiles. A sensitivity analysis was also conducted to study the impact of the Al content in a vehicle on the final outcomes. The GHG emissions and energy consumption could be further reduced when the Al content in an automobile increases.

It is now widely recognized that technological change will play a substantial role in reducing GHG emissions without compromising economic growth; hence, any better understanding of the process of technological innovation is likely to increase our knowledge of mitigation possibilities and costs. This paper explores how international knowledge flows affect the dynamics of the domestic R and D sector and the main economic and environmental variables. The analysis is performed using WITCH, a dynamic regional model of the world economy, in which energy-related technological change is endogenous. The focus is on disembodied energy R and D international spillovers. The knowledge pool from which regions draw foreign ideas differs between High Income and Low Income countries. Absorption capacity is also endogenous in the model. The basic questions are as follows. Do knowledge spillovers enhance energy-related technological innovation in different regions of the world? Does the speed of innovation increase? Or do free-riding incentives prevail and international spillovers crowd out domestic R and D efforts? What is the role of domestic absorption capacity and of policies designed to enhance it? Do greenhouse gas stabilization costs drop in the presence of international technological spillovers? The new specification of the WITCH model presented in this paper enables us to answer these questions. Our analysis shows that international knowledge spillovers tend to increase free-riding incentives and decrease the investments in energy R and D. The strongest cuts in energy R and D investments are recorded among High Income countries, where international knowledge flows crowd out domestic R and D efforts. The overall domestic pool of knowledge, and thus total net GHG stabilization costs, remain largely unaffected. International spillovers, however, are also an important policy channel. We therefore analyze the implication of a policy-mix in which climate policy is combined with a

To assess the effectiveness of urban energy conservation and GHG mitigation measures, a detailed Long-range Energy Alternatives Planning (LEAP) model is developed and applied to analyze the future trends of energy demand and GHG emissions in Xiamen city. Two scenarios have been designed to describe the future energy strategies in relation to the development of Xiamen city. The 'Business as Usual' scenario assumes that the government will do nothing to influence the long-term trends of urban energy demand. An 'Integrated' scenario, on the other hand, is generated to assess the cumulative impact of a series of available reduction measures: clean energy substitution, industrial energy conservation, combined heat and power generation, energy conservation in building, motor vehicle control, and new and renewable energy development and utilization. The reduction potentials in energy consumption and GHG emissions are estimated for a time span of 2007-2020 under these different scenarios. The calculation results in Xiamen show that the clean energy substitution measure is the most effective in terms of energy saving and GHG emissions mitigation, while the industrial sector has the largest abatement potential.

Trends in increasing urbanization, paired with a lack of ambitious action on larger scales, uniquely position cities to resume leadership roles in climate mitigation. While many cities have adopted ambitious long-term emission reduction goals, few have articulated how to reach them. This paper presents one of the first long-term scenarios of deep greenhouse gas abatement for a major U.S. city. Using a detailed, bottom-up scenario analysis, we investigate how Seattle might achieve its recently stated goal of carbon neutrality by the year 2050. The analysis demonstrates that a series of ambitious strategies could achieve per capita GHG reductions of 34% in 2020, and 91% in 2050 in Seattle's “core” emissions from the buildings, transportation, and waste sectors. We examine the pros and cons of options to get to, or beyond, net zero emissions in these sectors. We also discuss methodological innovations for community-scale emissions accounting frameworks, including a “core” emissions focus that excludes industrial activity and a consumption perspective that expands the emissions footprint and scope of policy solutions. As in Seattle, other communities may find the mitigation strategies and analytical approaches presented here are useful for crafting policies to achieve deep GHG-reduction goals. - Highlights: ► Cities can play a pivotal role in mitigating climate change. ► Strategies modeled achieve per-capita GHG reductions of 91% by 2050 in Seattle. ► We discuss methodological innovations in community-scale accounting frameworks. ► We weigh options for getting to, or beyond, zero GHG emissions. ► Other cities may adapt these measures and analytical approaches to curb emissions

Science.gov (United States)

Kutsch, Werner Leo

2016-04-01

The mission of the Integrated Carbon Observation System (ICOS RI) is to enable research to understand the greenhouse gas (GHG) budgets and perturbations. The ICOS RI provides the long-term observations required to understand the present state and predict future behaviour of the global carbon cycle and GHG emissions. Technological developments and implementations, related to GHGs, will be promoted by the linking of research, education and innovation. In order to provide this data ICOS RI is a distributed research infrastructure. The backbones of ICOS RI are the national measurement stations such as ICOS atmosphere, ecosystem and ocean stations. ICOS Central Facilities are the European level ICOS RI Centres, which have the specific tasks in collecting and processing the data and samples received from the national measurement networks. During the establishment of ICOS RI ethical guidelines were developed. These guidelines describe principles of ethics in the research activities that should be applied within ICOS RI. They should be acknowledged and followed by all researchers affiliated to ICOS RI and should be supported by all participating institutions. The presentation describes (1) the general challenge to develop ethical guidelines in a complex international infrastructure and (2) gives an overview about the content that includes different kinds of conflicts of interests, data ethics and social responsibility.

During 2011, the International Space Station reached an important milestone in the completion of assembly and the shift to the focus on a full and continuous utilization mission in space. The ISS partnership itself has also met a milestone in the coordination and cooperation of utilization activities including research, technology development and education. We plan and track all ISS utilization activities jointly and have structures in place to cooperate on common goals by sharing ISS assets and resources, and extend the impacts and efficiency of utilization activities. The basic utilization areas on the ISS include research, technology development and testing, and education/outreach. Research can be categorized as applied research for future exploration, basic research taking advantage of the microgravity and open space environment, and Industrial R&D / commercial research focused at industrial product development and improvement. Technology development activities range from testing of new spacecraft systems and materials to the use of ISS as an analogue for future exploration missions to destinations beyond Earth orbit. This presentation, made jointly by all ISS international partners, will highlight the ways that international cooperation in all of these areas is achieved, and the overall accomplishments that have come as well as future perspectives from the cooperation. Recently, the partnership has made special efforts to increase the coordination and impact of ISS utilization that has humanitarian benefits. In this context the paper will highlight tentative ISS utilization developments in the areas of Earth remote sensing, medical technology transfer, and education/outreach.

The complexity and challenges of determining GHG (greenhouse gas) emissions from grid electricity consumption and conservation in LCA (life cycle assessment) – A methodological review

International Nuclear Information System (INIS)

Soimakallio, Sampo; Kiviluoma, Juha; Saikku, Laura

2011-01-01

The way in which GHG (greenhouse gas) emissions associated with grid electricity consumption is handled in different LCA (life cycle assessment) studies, varies significantly. Apart from differences in actual research questions, methodological choices and data set selection have a significant impact on the outcomes. These inconsistencies result in difficulties to compare the findings of various LCA studies. This review paper explores the issue from a methodological point of view. The perspectives of ALCA (attributional life cycle assessment) and CLCA (consequential life cycle assessment) are reflected. Finally, the paper summarizes the key issues and provides suggestions on the way forward. The major challenge related to both of the LCA categories is to determine the GHG emissions of the power production technologies under consideration. Furthermore, the specific challenge in ALCA is to determine the appropriate electricity production mix, and in CLCA, to identify the marginal technologies affected and related consequences. Significant uncertainties are involved, particularly in future-related LCAs, and these should not be ignored. Harmonization of the methods and data sets for various purposes is suggested, acknowledging that selections might be subjective. -- Highlights: ► Methods to assess GHG emissions from grid electricity consumption in LCA vary. ► We explored the major challenges related to various methods. ► Significant uncertainties are involved particularly in future-related GHG emissions. ► The most appropriate method depends on the equity viewpoints.

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

International Nuclear Information System (INIS)

Chiotti, Q.; Urquizo, N.

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

Assessment of the GHG Reduction Potential from Energy Crops Using a Combined LCA and Biogeochemical Process Models: A Review

Directory of Open Access Journals (Sweden)

Dong Jiang

2014-01-01

Full Text Available The main purpose for developing biofuel is to reduce GHG (greenhouse gas emissions, but the comprehensive environmental impact of such fuels is not clear. Life cycle analysis (LCA, as a complete comprehensive analysis method, has been widely used in bioenergy assessment studies. Great efforts have been directed toward establishing an efficient method for comprehensively estimating the greenhouse gas (GHG emission reduction potential from the large-scale cultivation of energy plants by combining LCA with ecosystem/biogeochemical process models. LCA presents a general framework for evaluating the energy consumption and GHG emission from energy crop planting, yield acquisition, production, product use, and postprocessing. Meanwhile, ecosystem/biogeochemical process models are adopted to simulate the fluxes and storage of energy, water, carbon, and nitrogen in the soil-plant (energy crops soil continuum. Although clear progress has been made in recent years, some problems still exist in current studies and should be addressed. This paper reviews the state-of-the-art method for estimating GHG emission reduction through developing energy crops and introduces in detail a new approach for assessing GHG emission reduction by combining LCA with biogeochemical process models. The main achievements of this study along with the problems in current studies are described and discussed.

2013-01-01

In this study, DEA (data envelopment analysis) was applied to analyze the energy efficiency of wheat farms in order to separate efficient and inefficient growers and to calculate the wasteful uses of energy. Additionally, the degrees of TE (technical efficiency), PTE (pure technical efficiency) and SE (scale efficiency) were determined. Furthermore, the effect of energy optimization on GHG (greenhouse gas) emission was investigated and the total amount of GHG emission of efficient farms was compared with inefficient ones. Based on the results it was revealed that 18% of producers were technically efficient and the average of TE was calculated as 0.82. Based on the BCC (Banker–Charnes–Cooper) model 154 growers (59%) were identified efficient and the mean PTE of these farmers was found to be 0.99. Also, it was concluded that 2075.8 MJ ha −1 of energy inputs can be saved if the performance of inefficient farms rises to a high level. Additionally, it was observed that the total GHG emission from efficient and inefficient producers was 2713.3 and 2740.8 kg CO 2eq . ha −1 , respectively. By energy optimization the total GHG emission can be reduced to the value of 2684.29 kg CO 2eq . ha −1 . - Highlights: • 18% of producers were technically efficient and the average of TE was 0.82. • An average 2075.8 MJ ha −1 from energy input could be saved without reducing the yield. • GHG emission of efficient and inefficient producers was 2713.3 and 2740.8 kg CO 2eq. ha −1 . • Total GHG emission can be reduced to the value of 2684.29 kg CO 2eq. ha −1

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

The activities of the bus terminal, including loading-unloading passengers, bus idling, and bus movements at the terminal, will emit GHG’s emission. This research analyzes GHG emission from four terminals, i.e., Mangkang, Terboyo, Penggaron, and Sukun in Semarang City. The emission was estimated by observing detail activities of public transport means, especially for moving and idling time. The emission was calculated by Tier 2 method based on the vehicle type as well as fuel consumption. The highest CO2e during vehicle movements at Sukun area was contributed by large bus about 2.08 tons/year, while at Terboyo terminal was contributed by medium bus about 347.97 tons/year. At Mangkang terminals, the highest emission for vehicle movements was attributed by medium bus as well of about 53.18 tons/year. At last, Penggaron terminal’s highest GHG emission was attributed by BRT about 26.47 tons/year. During idling time, the highest contributor to CO2e was the large bus at the three terminals, i.e., Sukun of 43.53 tons/year, Terboyo of 196.56 tons/year, and Mangkang of 84.26 tons/year, while at Penggaron, BRT dominated with CO2e of 26.47 tons/year. The management of public transport in terminals is crucial to mitigate the emission related to bus terminals activities.

Abatement cost of GHG emissions for wood-based electricity and ethanol at production and consumption levels.

Directory of Open Access Journals (Sweden)

Puneet Dwivedi

Full Text Available Woody feedstocks will play a critical role in meeting the demand for biomass-based energy products in the US. We developed an integrated model using comparable system boundaries and common set of assumptions to ascertain unit cost and greenhouse gas (GHG intensity of electricity and ethanol derived from slash pine (Pinus elliottii at the production and consumption levels by considering existing automobile technologies. We also calculated abatement cost of greenhouse gas (GHG emissions with respect to comparable energy products derived from fossil fuels. The production cost of electricity derived using wood chips was at least cheaper by 1 ¢ MJ-1 over electricity derived from wood pellets. The production cost of ethanol without any income from cogenerated electricity was costlier by about 0.7 ¢ MJ-1 than ethanol with income from cogenerated electricity. The production cost of electricity derived from wood chips was cheaper by at least 0.7 ¢ MJ-1 than the energy equivalent cost of ethanol produced in presence of cogenerated electricity. The cost of using ethanol as a fuel in a flex-fuel vehicle was at least higher by 6 ¢ km-1 than a comparable electric vehicle. The GHG intensity of per km distance traveled in a flex-fuel vehicle was greater or lower than an electric vehicle running on electricity derived from wood chips depending on presence and absence of GHG credits related with co-generated electricity. A carbon tax of at least $7 Mg CO2e-1 and $30 Mg CO2e-1 is needed to promote wood-based electricity and ethanol production in the US, respectively. The range of abatement cost of GHG emissions is significantly dependent on the harvest age and selected baseline especially for electricity generation.

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

The typical Western diet is associated with high levels of greenhouse gas (GHG) emissions and with obesity and other diet-related diseases. This study aims to determine the impact of adjustments to the current diet at specific moments of food consumption, to lower GHG emissions and improve diet quality. Food consumption in the Netherlands was assessed by two non-consecutive 24-h recalls for adults aged 19-69 years (n = 2102). GHG emission of food consumption was evaluated with the use of life cycle assessments. The population was stratified by gender and according to tertiles of dietary GHG emission. Scenarios were developed to lower GHG emissions of people in the highest tertile of dietary GHG emission; 1) reducing red and processed meat consumed during dinner by 50% and 75%, 2) replacing 50% and 100% of alcoholic and soft drinks (including fruit and vegetable juice and mineral water) by tap water, 3) replacing cheese consumed in between meals by plant-based alternatives and 4) two combinations of these scenarios. Effects on GHG emission as well as nutrient content of the diet were assessed. The mean habitual daily dietary GHG emission in the highest tertile of dietary GHG emission was 6.7 kg CO 2 -equivalents for men and 5.1 kg CO 2 -equivalents for women. The scenarios with reduced meat consumption and/or replacement of all alcoholic and soft drinks were most successful in reducing dietary GHG emissions (ranging from - 15% to - 34%) and also reduced saturated fatty acid intake and/or sugar intake. Both types of scenarios lead to reduced energy and iron intakes. Protein intake remained adequate. Reducing the consumption of red and processed meat during dinner and of soft and alcoholic drinks throughout the day leads to significantly lower dietary GHG emissions of people in the Netherlands in the highest tertile of dietary GHG emissions, while also having health benefits.

2008-01-01

The evaluation of life cycle greenhouse gas emissions from power generation with carbon capture and storage (CCS) is a critical factor in energy and policy analysis. The current paper examines life cycle emissions from three types of fossil-fuel-based power plants, namely supercritical pulverized coal (super-PC), natural gas combined cycle (NGCC) and integrated gasification combined cycle (IGCC), with and without CCS. Results show that, for a 90% CO 2 capture efficiency, life cycle GHG emissions are reduced by 75-84% depending on what technology is used. With GHG emissions less than 170 g/kWh, IGCC technology is found to be favorable to NGCC with CCS. Sensitivity analysis reveals that, for coal power plants, varying the CO 2 capture efficiency and the coal transport distance has a more pronounced effect on life cycle GHG emissions than changing the length of CO 2 transport pipeline. Finally, it is concluded from the current study that while the global warming potential is reduced when MEA-based CO 2 capture is employed, the increase in other air pollutants such as NO x and NH 3 leads to higher eutrophication and acidification potentials

Reports of hundreds of peatlands across basins in the West and Central Amazon suggest they play an important, previously not considered regional role in organic carbon (OC) and GHG dynamics. Amazon peatlands store ˜3-6 Gt of OC in their waterlogged soils with strong potential for conversion and release of GHG, in fact our recent, and others', efforts have confirmed variable levels of GHG emissions (CO2, N2O, CH4), as well as variable microbial communities across rich to poor soil peatlands. Here, we report early results of quantification of different components making up the aboveground C stocks, the rates and paths for GHG release, and microbial organisms occurring in three ecologically distinct peatland types in the Pastaza-Marañon region of the Peruvian Amazon. Evaluations were done in duplicated continuous monitoring plots established since 2015 at a "palm swamp" (PS), poor "pole forest" (pPF) and a rich "forested" (rF) peatlands. Although overall vegetation "structure" with a few dominant plus several low frequency species was common across the three sites, their botanical composition and tree density was highly contrasting. Aboveground C stocks content showed the following order among sites: rF>PS>pPF, and hence we tested whether this differences can have a direct effect on CH4 emissions rates. CH4 emissions rates from soils were observed in average at 11, 6, and 0.8 mg-C m-2 h-1for rF, PS, and pPF respectively. However, these estimated fluxes needed to be revised when we develop quantifications of CH4 emissions from tree stems. Tree stem fluxes were detected showing a broad variation with nearly nill emissions in some species all the way to maximum fluxes near to ˜90 mg-C m-2 h-1 in other species. Mauritia flexuosa, a highly dominant palm species in PS and ubiquitous to the region, showed the highest ranges of CH4 flux. In the PS site, overall CH4 flux estimate increased by ˜50% when including stem emission weighted by trees' species, density and heights

Internal emitter research and standard setting

International Nuclear Information System (INIS)

Stannard, J.N.

The history of the use of data from internal emitter research in the derivation of safety standards is reviewed. At first, observed biological effects were correlated with body burdens or exposure levels. This direct approach is illustrated by detailed accounts of the cases of uranium and plutonium. In the 1950's, when it was decided to provide standards for over 200 isotopes, the direct approach was replaced by a system of calculations. This necessitated changes in internal emitter research programs to provide metabolic data, and the development of models such as Reference Man and the Lung and Gastrointestinal Tract models. The continuing contribution of internal emitter research to standard setting can be seen in the references quoted in the metabolic data section of the new ICRP report (ICRP Publication 30). Present trends suggest a possible return to the direct use of internal emitter effects data for obtaining risk estimates. (U.K.)

Mobile-Source GHG Modeling Institutions and Capacities in China:Findings Based on Structured Interviews and On-Line Surveys

Institute of Scientific and Technical Information of China (English)

Jiangping; ZHOU; Yin; WANG

2014-01-01

This paper provides an overview of practices of mobile-source greenhouse gas(GHG) modeling in China and related data sharing issues. It is based on structured phone interviews and two on-line surveys conducted in 2011 and finds that most cities have transportation-land use models but that few have mobile-source GHG models. A group of entities housed in the government have the strongest GHG modeling capacities and dominate the relevant consulting market. Data hoarding of public entities is the biggest barrier for entities without government ties to compete in the market. The reasons for data hoarding include government concerns over political implications of data release, a tradition of data hoarding, and a lack of confidence in reliability and accuracy of the data.

Highlights: • Conduct a life cycle energy use and GHG emissions of olefins production processes. • Analyse effects of carbon capture and efficiency on alternative olefins production. • Analyse life cycle performance of Chinese olefins industry in three key periods. • Present the advantages and challenges of alternative olefins routes. - Abstract: Olefins are important platform chemicals widely used in industry. In terms of the short supply of oil resources, natural gas and coal are two significant alternative feedstocks. In this paper, energy consumption and GHG emissions of olefins production are analysed with life cycle assessment methods. Results showed the energy consumption and GHG emissions of natural gas-to-olefins are roughly equivalent to those of oil-to-olefins, while coal-to-olefins suffers from higher energy consumption and serious GHG emissions, including 5793 kg eq. CO 2 /t olefins of direct emissions and 5714 kg eq. CO 2 /t olefins of indirect emissions. To address the problem, the effect of carbon capture on coal-to-olefins is investigated. In comprehensive consideration of energy utilization, environmental impact, and economic benefit, the coal-to-olefins with 80% CO 2 capture of the direct emissions is found to be an appropriate choice. With this carbon capture configuration, the direct emissions of the coal-to-olefins are reduced to 1161 kg eq. CO 2 /t olefins. However, the indirect emissions are still not captured, which should be strictly monitored and significantly reduced. Finally, a scenario analysis is conducted to estimate resource utilization and GHG emissions of olefins production of China in 2020. Several suggestions are also proposed for policy making on the sustainable development of olefins industry

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

Graphical abstract: - Highlights: • Obtained Pareto fronts of LEC, power supply reliability (PSR) and ICC/GHG emission. • Pareto surface was observed for smaller ICGs when considering LEC–PSR–GHG. • Shape of the LEC–PSR–ICC Pareto front gradually changes with ICG capacity. • Importance of multi-criterion decision-making after multi objective optimization. - Abstract: Expanding existing Internal Combustion Generator (ICG) systems by combining renewable energy sources is getting popular due to global concern on emission of green house gases (GHG) and increasing fossil fuel costs. Life cycle cost, initial capital cost (ICC), power supply reliability of the system, and GHG emission by ICG are factors to be considered in this process. Pareto front of Levelized Energy Cost (LEC)–Unmet Load Fraction (ULF)–GHG emission was taken in this study for four different expansion scenarios. Furthermore, Pareto front of ICC–LE–ULF was taken for three different expansion scenarios in order to analyze the impact of renewable energy integration. The results clearly depict that characteristics of the Pareto front varies with the scale of expansion and objectives taken for the optimization. A detailed analysis was conducted for a scale up problem with a 4 kVA ICG by using the Pareto fronts obtained

This study advances an integrated MSW management model under inexact input information for the city of Beijing, China. The model is capable of simultaneously generating MSW management policies, performing GHG emission control, and addressing system uncertainty. Results suggest that: (1) a management strategy with minimal system cost can be obtained even when suspension of certain facilities becomes unavoidable through specific increments of the remaining ones; (2) expansion of facilities depends only on actual needs, rather than enabling the full usage of existing facilities, although it may prove to be a costly proposition; (3) adjustment of waste-stream diversion ratio directly leads to a change in GHG emissions from different disposal facilities. Results are also obtained from the comparison of the model with a conventional one without GHG emissions consideration. It is indicated that (1) the model would reduce the net system cost by [45, 61]% (i.e., [3173, 3520] million dollars) and mitigate GHG emissions by [141, 179]% (i.e., [76, 81] million tons); (2) increased waste would be diverted to integrated waste management facilities to prevent overmuch CH4 emission from the landfills.

In order to provide discussion materials for measures to achieve the GHG emission reduction target, investigations and discussions have been made on the following subjects: cost effectiveness of reducing GHG emission by target countries and target technologies, use of maps and databases on the possible reduction quantity of GHG emission, the targeted countries and business categories. Regarding the target countries, investigations were made on the general situation of the energy consumption efficiency, difference between their energy consumption efficiency by industries and that in Japan, and the GHG emission quantities by sectors. As a result, 31 counties hopeful in reducing CO2 emission were selected. With regard to technologies to reduce CO2 emission, technologies having been practically used and proliferated in Japan were used as the base, whereas 43 technologies were systematized for such departments as industries, business operations, households, and transportation. According to a trial calculation on the effect of CO2 emission reduction, if the 43 technologies are applied to the 31 target countries, CO2 emission reduction of 698 million tons as a whole would be possible, for which the required expense was calculated as 114.4 trillion yen. In evaluating the CO2 emission reducing technologies, the cost effectiveness of each technology was evaluated by cost per GHG emission reduction of 1t-CO2. (NEDO)

Empirical greenhouse gas (GHG) flux estimates from diverse peatlands are required in order to derive emission factors for managed peatlands. This study on a drained fen peatland quantified the annual GHG balance (Carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and C exported in crop yield) from spring barley (SB) and reed canary grass (RCG) using static opaque chambers for GHG flux measurements and biomass yield for indirectly estimating gross primary production (GPP). Estimates of ecosystem respiration (ER) and GPP were compared with more advanced but costly and labor-intensive dynamic chamber studies. Annual GHG balance for the two cropping systems was 4.0 ± 0.7 and 8.1 ± 0.2 Mg CO2-Ceq ha(-1) from SB and RCG, respectively (mean ± standard error, n = 3). Annual CH4 emissions were negligible (peatland cropped to SB and RCG and presented a valid alternative to estimating the full GHG balance by dynamic chambers.

Green House Gas (GHG) emissions are the major cause of global warming and climate change. Carbon dioxide (CO2) is the main GHG emitted through human activities, at the household level, by burning fuels for cooking and lighting. As per the 2006 methodology of the Inter-governmental Panel on Climate Change (IPCC), the energy sector is divided into various sectors like electricity generation, transport, fugitive, 'other' sectors, etc. The 'other' sectors under energy include residential, commercial, agriculture and fisheries. Time series GHG emission estimates were prepared for the residential, commercial, agriculture and fisheries sectors in India, for the time period 2005 to 2014, to understand the historical emission changes in 'other' sector. Sectoral activity data, with respect to fuel consumption, were collected from various ministry reports like Indian Petroleum and Natural Gas Statistics, Energy Statistics, etc. The default emission factor(s) from IPCC 2006 were used to calculate the emissions for each activity and sector-wise CO2, CH4, N2O and CO2e emissions were compiled. It was observed that the residential sector generates the highest GHG emissions, followed by the agriculture/fisheries and commercial sector. In the residential sector, LPG, kerosene, and fuelwood are the major contributors of emissions, whereas diesel is the main contributor to the commercial, agriculture and fisheries sectors. CO2e emissions have been observed to rise at a cumulative annual growth rate of 0.6%, 9.11%, 7.94% and 5.26% for the residential, commercial, agriculture and fisheries sectors, respectively. In addition to the above, a comparative study of the sectoral inventories from the national inventories, published by Ministry of Environment, Forest and Climate Change, for 2007 and 2010 was also performed.

Greenhouse gas (GHG) flux variations in Arctic tundra environments are important to understand because of the vast amount of soil carbon stored in these regions and the potential of these regions to convert from a global carbon sink to a source under warmer conditions. Multiple factors potentially contribute to GHG flux variations observed in these environments, including snowmelt timing, growing season length, active layer thickness, water table variations, and temperature fluctuations. The objectives of this study are to investigate temporal variability in CO2 and CH4 fluxes at Barrow, AK over three successive growing seasons (2012-14) and to determine the factors influencing this variability using a novel entropy-based classification scheme. We analyzed soil, vegetation, and climate parameters as well as GHG fluxes at multiple locations within low-, flat- and high-centered polygons at Barrow, AK as part of the Next Generation Ecosystem Experiment (NGEE) Arctic project. Entropy results indicate that different environmental factors govern variability in GHG fluxes under different spatiotemporal settings. In particular, flat-centered polygons are more likely to become significant sources of CO2 during warm and dry years as opposed to high-centered polygons that contribute considerably to CO2 emissions during cold and wet years. In contrast, the highest CH4 emissions were always associated with low-centered polygons. Temporal variability in CO2 fluxes was primarily associated with factors affecting soil temperature and/or vegetation dynamics during early and late season periods. Temporal variability in CH4 fluxes was primarily associated with changes in vegetation cover and its covariability with primary controls such as seasonal thaw—rather than direct response to changes in soil moisture. Overall, entropy results document which factors became important under different spatiotemporal settings, thus providing clues concerning the manner in which ecosystem

Highlights: • Life cycle energy use and GHG emissions are assessed for SNG and power cogeneration. • A model based on a Chinese domestic database is developed for evaluation. • Cogeneration shows lower GHG emissions than coal-power pathway. • Cogeneration has lower life cycle energy use than supercritical coal-power pathway. • Cogeneration is a good option to implement China’s clean coal technologies. - Abstract: Life cycle energy use and GHG emissions are assessed for coal-based synthetic natural gas (SNG) and power cogeneration/polygenereation (PG) technology and its competitive alternatives. Four main SNG applications are considered, including electricity generation, steam production, SNG vehicle and battery electric vehicle (BEV). Analyses show that if SNG is produced from a single product plant, the lower limits of its life cycle energy use and GHG emissions can be comparable to the average levels of coal-power and coal-BEV pathways, but are still higher than supercritical and ultra supercritical (USC) coal-power and coal-BEV pathways. If SNG is coproduced from a PG plant, when it is used for power generation, steam production, and driving BEV car, the life cycle energy uses for PG based pathways are typically lower than supercritical coal-power pathways, but are still 1.6–2.4% higher than USC coal-power pathways, and the average life cycle GHG emissions are lower than those of all coal-power pathways including USC units. If SNG is used to drive vehicle car, the life cycle energy use and GHG emissions of PG-SNGV-power pathway are both much higher than all combined coal-BEV and coal-power pathways, due to much higher energy consumption in a SNG driven car than in a BEV car. The coal-based SNG and power cogeneration technology shows comparable or better energy and environmental performances when compared to other coal-based alternatives, and is a good option to implement China’s clean coal technologies.

quantifications will allow for evaluating the most suitable strategies for developing sustainable irrigation agrosystems in the region. The quantification of SOC stocks was done within equivalent soil units in each area, and for each level of comparison. Soil organic C stocks were quantified using the area-frame randomized soil sampling protocol (Stolbovoy et al., 2007), in the tilled layer (0-30 cm). GHG balances were calculated from inputs information obtained from farmers, using tools developed by the regional agricultural research institute (INTIA), adapted to the local characteristics of agriculture. The results corresponding to the comparison between dryland and irrigated agrosystems showed differences both in terms of SOC storage and GHG balances in the two studied areas. Irrigated fields had significantly greater stocks of SOC on average, although net organic C storage was significantly affected by soil and crop type. Also, organic fertilization in dryland resulted in significantly more SOC stored in the soil. Net GHG balances were greatly affected by the type of crops and their management, in particular fertilization strategies. As a result, net balances in terms of GHG emissions and mitigation varied greatly among irrigated systems, and in comparison to dryland systems.

Assessment of GHG Emission Reduction Potential from Source-separated Organic Waste (SOW) Management: Case Study in a Higher Educational Institution in Malaysia

In Malaysia, the greenhouse gases (GHGs) emissions reduction via composting of source-separated organic waste (SOW) in municipal solid waste (MSW) has not been assessed. Assessment of GHG emissions reduction via composting of SOW is important as environmental impacts from waste management are waste-specific and local-specific. The study presents the case study for potential carbon reduction via composting of SOW in University of Malaya (UM). In this study, a series of calculations were used to evaluate the GHG emission of different SOW management scenarios. The calculations based on IPCC calculation methods (AM0025) include GHGs emissions from land filling, fuel consumption in transportation and SOW composting activity. The methods were applied to assess the GHG emissions from five alternative SOW management scenarios in UM. From the baseline scenario (S0), a total of 1,636.18 tCO2e was generated. In conjunction with target of 22 % recycling rate, as shown in S1, 14 % reduction in potential GHG emission can be achieved. The carbon reduction can be further enhanced by increasing the SOW composting capacity. The net GHG emission for S1, S2, S3 and S4 were 1,399.52, 1,161.29, 857.70 and 1,060.48 tCO2e, respectively. In general, waste diversion for composting proved a significant net GHG emission reduction as shown in S3 (47 %), S4 (35 %) and S2 (29 %). Despite the emission due to direct on-site activity, the significant reduction in methane generation at landfill has reduced the net GHG emission. The emission source of each scenario was studied and analysed. (author)

This paper focuses on Ireland's ambitious target for 2020 to reduce greenhouse gas (GHG) emissions by 20% below 2005 levels for sectors not covered by ETS (Non-ETS). Ireland is an interesting case study due to the role of agriculture (a particularly challenging sector with regard to GHG emissions reduction), that represents 29% of Ireland's GHG emissions compared with less than 10% for the EU. The analysis is carried out with the Irish TIMES model, a bottom-up energy systems modelling tool with detailed characterization of Ireland's energy system. The paper uses scenario analysis to provide pathways that demonstrate how Ireland can meet the non-ETS target at least cost. The paper considers the impacts (in terms of different technology choices and higher marginal abatement costs) arising from higher targets for the energy system to compensate for growth in agriculture activity and low mitigation potential in that sector. The results point to a need to reconsider Ireland's renewable energy focus, with a need for increased effort in renewable transport and renewable heat in particular. The results also point to significant electrification of residential heating. The results also point to a high marginal abatement cost (€213/tCO 2 ), which challenges the analysis carried out at EU level to establish Ireland's non-ETS target. - Highlights: • Techno-economic energy model to deliver EU GHG mitigation target by 2020 in Ireland. • Agriculture represents nearly half of Non-ETS emissions in Ireland. • The target set for Non-ETS GHG for Ireland is far from a cost optimal target. • The results point to a need to reconsider Ireland's renewable energy focus. • Key pathways: electrification of heating in buildings and biofuels in transport

The Building Technologies Office (BTO) works with researchers and industry partners to develop and deploy technologies that can substantially reduce energy consumption and greenhouse gas (GHG) emissions in residential and commercial buildings. This opportunity assessment aims to advance BTO’s energy savings, GHG reduction, and other program goals by identifying research and development (R&D) initiatives for joining technologies in heating, ventilation, air-conditioning, and refrigeration (HVAC&R) systems. Improving joining technologies for HVAC&R equipment has the potential to increase lifetime equipment operating efficiency, decrease equipment and project cost, and most importantly reduce hydroflourocarbon (HFC) refrigerant leakage to support HFC phasedown and GHG reduction goals.

2012-01-01

Electric vehicles have recently been gaining increasing worldwide interest as a promising potential long-term solution to sustainable personal mobility; in particular, battery electric vehicles (BEVs) offer zero tailpipe emissions. However, their true ability to contribute to greenhouse gas (GHG) emissions reductions can only be properly assessed by comparing a life cycle assessment of their GHG emissions with a similar assessment for conventional internal combustion vehicles (ICVs). This paper presents an analysis for vehicles typically expected to be introduced in 2015 in two example markets (the UK and California), taking into account the impact of three important factors: •Like-for-like vehicle comparison and effect of real-world driving conditions. •Accounting for the GHG emissions associated with meeting the additional electricity demand for charging the batteries. •GHG emissions associated with vehicle manufacture, disposal, etc. This work demonstrates that all of these factors are important and emphasises that it is therefore crucial to clearly define the context when presenting conclusions about the relative GHG performance of BEVs and ICVs – such relative performance depends on a wide range of factors, including the marginal regional grid GHG intensity, vehicle size, driving pattern, loading, etc. - Highlights: ► Develops new insights into the life cycle GHG emissions of electric vehicles. ► Addresses like-for-like vehicle comparison and effect of real-world driving. ► Accounts for marginal GHG intensity of the electricity used to charge EVs. ► Accounts for the GHG emissions associated with vehicle manufacture and disposal.

2009-07-01

Full Text Available Abstract Background Health literacy is an increasingly important topic in both the policy and research agendas of many countries. During the recent 36th Annual Meeting of the North American Primary Care Research Group, the authors led an audio-taped 3-hour forum, "Studying Health Literacy: Developing an International Collaboration," where the current state of health literacy (HL in the United States (US and United Kingdom (UK was presented and attendees were encouraged to debate a future research agenda. Discussion of Forum Themes The debate centred around three distinct themes, including: (1 refining HL definitions and conceptual models, (2 HL measurement and assessment tools, and (3 developing a collaborative international research agenda. The attendees agreed that future research should be theoretically grounded and conceptual models employed in studies should be explicit to allow for international comparisons to be drawn. Summary and Authors Reflections The importance of HL research and its possible contribution to health disparities is becoming increasingly recognised internationally. International collaborations and comparative studies could illuminate some of the possible determinants of disparities, and also possibly provide a vehicle to examine other research questions of interest.

New power expansion strategy and a low GHG emitting economy in Korea

International Nuclear Information System (INIS)

Chung, W. S.; Yun, S. W.; Lee, D. S.; Jeong, J. W.

2008-01-01

According to mounting environmental concerns and an increased number of environmental restrictions, a new power expansion strategy is being suggested in Korea. Low carbon emitting technologies are a cost- and environment-effective renewable energy technology for producing electricity (except large hydropower) and the fastest growing market after the launch of the 'The 3. Basic Plan for Long-Term Electricity Supply and Demand' in 2006 in Korea. Even though some renewable power plants don't use any fuel or materials during their operation, they still contribute to climate change. This is due to the emission of greenhouse gases (GHG) from the fossil fuels combusted for their components manufacturing, construction, and dismantling. So the aim of this analysis is to assess the Global Warming Potential (GWP) during the whole life cycle for each candidate technology and to estimate how much they contribute to GHG emissions by introducing low-carbon energy sources up to 2020 in Korea.

Highlights: • GHG savings are in the order of 600–1000 kg CO 2 -eq. per Mg of MBM treated. • Energy recovery differed in terms of energy products and efficiencies. • The results were largely determined by use of the products for energy purposes. - Abstract: Meat-and-bone-meal (MBM) produced from animal waste has become an increasingly important residual fraction needing management. As biodegradable waste is routed away from landfills, thermo-chemical treatments of MBM are considered promising solution for the future. Pyrolysis and gasification of MBM were assessed based on data from three experimental lab and pilot-scale plants. Energy balances were established for the three technologies, providing different outcomes for energy recovery: bio-oil was the main product for the pyrolysis system, while syngas and a solid fraction of biochar were the main products in the gasification system. These products can be used – eventually after upgrading – for energy production, thereby offsetting energy production elsewhere in the system. Greenhouse gases (GHG) accounting of the technologies showed that all three options provided overall GHG savings in the order of 600–1000 kg CO 2 -eq. per Mg of MBM treated, mainly as a consequence of avoided fossil fuel consumption in the energy sector. Local conditions influencing the environmental performance of the three systems were identified, together with critical factors to be considered during decision-making regarding MBM management

2017-01-01

This study explores the impact of improvements in energy research development (ERD) on greenhouse gas (GHG) emissions using environmental Kuznets curve hypothesis for 28 OECD countries over the period of 1990–2014. In doing so, we have employed a panel data where public budget in energy research development and demonstration (ERD&D) has transformed into a finite inverted V-lag distribution model developed by De Leeuw (1962). This model considers that energy innovation accumulates in time and presents empirical evidence, how energy innovation contributes in reducing energy intensity and environmental pollution as well. Our results indicate that energy innovation measures require lapses of time to reach their full effect i.e. innovation applied to measures for environmental correction does not reach its whole effect immediately, requiring instead a certain amount of time to pass. Innovation policies have recommended for improving environmental quality. - Highlights: • This study analyses the impact of public budget in energy RD&D for 28 OECD countries on environmental quality. • Energy innovation contributes positively to reduce greenhouse gas emissions. • Advances in energy technology seem to be the key of improved environmental quality.

A comparison of justice frameworks for international research.

Science.gov (United States)

Pratt, Bridget; Loff, Bebe

2015-07-01

Justice frameworks have been developed for international research that provide guidance on the selection of research targets, ancillary care, research capacity strengthening, and post-trial benefits. Yet there has been limited comparison of the different frameworks. This paper examines the underlying aims and theoretical bases of three such frameworks--the fair benefits framework, the human development approach and research for health justice--and considers how their aims impact their guidance on the aforementioned four ethical issues. It shows that the frameworks' underlying objectives vary across two dimensions. First, whether they seek to prevent harmful or exploitative international research or to promote international research with health benefits for low and middle-income countries. Second, whether they address justice at the micro level or the macro level. The fair benefits framework focuses on reforming contractual elements in individual international research collaborations to ensure fairness, whereas the other two frameworks aim to connect international research with the reduction of global health inequities. The paper then highlights where there is overlap between the frameworks' requirements and where differences in the strength and content of the obligations they identify arise as a result of their varying objectives and theoretical bases. In doing so, it does not offer a critical comparison of the frameworks but rather seeks to add clarity to current debates on justice and international research by showing how they are positioned relative to one another.

2015-09-15

The greenhouse gases and black carbon emission inventory from IPCC key category Energy was accomplished for the Mezquital Valley, one of the most polluted regions in Mexico, as the Mexico City wastewater have been continuously used in agricultural irrigation for more than a hundred years. In addition, thermoelectric, refinery, cement and chemistry industries are concentrated in the southern part of the valley, near Mexico City. Several studies have reported air, soil, and water pollution data and its main sources for the region. Paradoxically, these sources contaminate the valley, but boosted its economic development. Nevertheless, no research has been done concerning GHG emissions, or climate change assessment. This paper reports inventories performed by the 1996 IPCC methodology for the baseline year 2005. Fuel consumption data were derived from priority sectors such as electricity generation, refineries, manufacturing & cement industries, transportation, and residential use. The total CO{sub 2} emission result was 13,894.9 Gg, which constituted three-quarters of Hidalgo statewide energy category. The principal CO{sub 2} sources were energy transformation (69%) and manufacturing (19%). Total black carbon emissions were estimated by a bottom-up method at 0.66 Gg. The principal contributor was on-road transportation (37%), followed by firewood residential consumption (26%) and cocked brick manufactures (22%). Non-CO{sub 2} gas emissions were also significant, particularly SO{sub 2} (255.9 Gg), which accounts for 80% of the whole Hidalgo State emissions. Results demonstrated the negative environmental impact on Mezquital Valley, caused by its role as a Megacity secondary fuel and electricity provider, as well as by the presence of several cement industries. - Highlights: • First GHG & black carbon inventory for Mezquital Valley: Mexico City energy supplier • Energy industries caused the largest CO{sub 2} and SO{sub 2} emissions from residual fuel oil. • Diesel

The influence of urban form on GHG emissions in the U.S. household sector

International Nuclear Information System (INIS)

Lee, Sungwon; Lee, Bumsoo

2014-01-01

To better understand the role of sustainable urban development in greenhouse gas (GHG) mitigation, this study examines the paths by which urban form influences an individual household's carbon dioxide emissions in the 125 largest urbanized areas in the U.S. Our multilevel SEM analyses show that doubling population-weighted density is associated with a reduction in CO 2 emissions from household travel and residential energy consumption by 48% and 35%, respectively. Centralized population and polycentric structures have only a moderate impact in our analyses. Given that household travel and residential energy use account for 42% of total U.S. carbon dioxide emissions, these findings highlight the importance of smart growth policies to build more compact and transit friendly cities as a crucial part of any strategic efforts to mitigate GHG emissions and to stabilize climate. - Highlights: • We examine how urban form influences household CO 2 emissions using a multilevel SEM. • Doubling population-weighted density is associated with a 48% reduction in CO 2 emissions from household travel. • Doubling population-weighted density is associated with a 35% reduction in CO 2 emissions from residential energy use. • Doubling per capita transit subsidy is associated with a 46% lower VMT and 18% reduction in transportation CO 2 emissions. • Smart growth policies should be a crucial part of any strategic efforts to mitigate GHG emissions and stabilize climate

Sustainable passenger road transport scenarios to reduce fuel consumption, air pollutants and GHG (greenhouse gas) emissions in the Mexico City Metropolitan Area

International Nuclear Information System (INIS)

Chavez-Baeza, Carlos; Sheinbaum-Pardo, Claudia

2014-01-01

This paper presents passenger road transport scenarios that may assist the MCMA (Mexico City Metropolitan Area) in achieving lower emissions in both criteria air pollutants (CO, NO x , NMVOC (non-methane volatile organic compounds), and PM 10 ) and GHG (greenhouse gas) (CH 4 , N 2 O and CO 2 ), while also promoting better mobility and quality of life in this region. We developed a bottom-up model to estimate the historical trends of energy demand, criteria air pollutants and GHG emissions caused by passenger vehicles circulating in the Mexico City Metropolitan Area (MCMA) in order to construct a baseline scenario and two mitigation scenarios that project their impact to 2028. Mitigation scenario “eff” considers increasing fuel efficiencies and introducing new technologies for vehicle emission controls. Mitigation scenario “BRT” considers a modal shift from private car trips to a Bus Rapid Transport system. Our results show significant reductions in air pollutants and GHG emissions. Incentives and environmental regulations are needed to enable these scenarios. - Highlights: • More than 4.2 million passenger vehicles in the MCMA (Mexico City Metropolitan Area) that represent 61% of criteria pollutants and 44% of GHG (greenhouse gas) emissions. • Emissions of CO, NO x and NMVOC (non-methane volatile organic compounds) in baseline scenario decrease with respect to its 2008 value because emission standards. • Emissions of PM 10 and GHG increase in baseline scenario. • Emissions of PM 10 and GHG decrease in eff + BRT scenario from year 2020. • Additional reductions are possible with better standards for diesel vehicles and other technologies

Global Health Governance at a Crossroads.

This review takes stock of the global health governance (GHG) literature. We address the transition from international health governance (IHG) to global health governance, identify major actors, and explain some challenges and successes in GHG. We analyze the framing of health as national security, human security, human rights, and global public good, and the implications of these various frames. We also establish and examine from the literature GHG's major themes and issues, which include: 1) persistent GHG problems; 2) different approaches to tackling health challenges (vertical, horizontal, and diagonal); 3) health's multisectoral connections; 4) neoliberalism and the global economy; 5) the framing of health (e.g. as a security issue, as a foreign policy issue, as a human rights issue, and as a global public good); 6) global health inequalities; 7) local and country ownership and capacity; 8) international law in GHG; and 9) research gaps in GHG. We find that decades-old challenges in GHG persist and GHG needs a new way forward. A framework called shared health governance offers promise.

High spatial and temporal variability is mutual feature for most forest soils that is especially obvious in case of their carbon stocks and GHG fluxes. This phenomenon is generally well-known but not so often becomes the object of special precision investigation in detail and small scales so there are still serious gaps in its principal factors understanding due to their high bioclimatic, regional, landscape, tree species and temporal variability. Southern taiga is one of the most environmentally important world zonal forest ecosystems due to its still comparatively intensive carbon biogeochemical cycle and huge area in the northern Eurasia with strong anthropogenic impacts by Western & Central European and Southern & Eastern Asian regions. Central Forest Biospheric Reserve (Tver region, 360 km to North-West from Moscow) is the principal southern-taiga reserve in the European territory of Russia. Since start of its research activity in 1939 the reserve became the regional center of mature spruce ecosystem structure and dynamics investigation. In 1970-1980-s there have been done complex investigations of windthrow soil patterns and fallow-forest successions. Since middle of 1990-s the ecosystem-level GHG fluxes have been observed by eddy covariance method. Since 2012 the detailed year-round monitoring is running in the southern-taiga zonal station of the regional system RusFluxNet with especial attention on the soil carbon stocks and GHG fluxes spatial variability and dynamics due to windthrow and fallow-forest successions (in frame of RF Governmental projects #11.G34.31.0079 and #14.120.14.4266). Soil carbon dynamics is investigated in decades-hundred-year chronosequences of dominated parcels and different-size windthrow soil cover patterns, including direct investigation during last 33 years with detailed mapping, soil profile morphometrics and bulk density, morphogenetic and statistical analysis of mass data. Morphogenetic analysis of microrelief, soil profile

Model and algorithm for bi-fuel vehicle routing problem to reduce GHG emissions.

Abdoli, Behroz; MirHassani, Seyed Ali; Hooshmand, Farnaz

Because of the harmful effects of greenhouse gas (GHG) emitted by petroleum-based fuels, the adoption of alternative green fuels such as biodiesel and compressed natural gas (CNG) is an inevitable trend in the transportation sector. However, the transition to alternative fuel vehicle (AFV) fleets is not easy and, particularly at the beginning of the transition period, drivers may be forced to travel long distances to reach alternative fueling stations (AFSs). In this paper, the utilization of bi-fuel vehicles is proposed as an operational approach. We present a mathematical model to address vehicle routing problem (VRP) with bi-fuel vehicles and show that the utilization of bi-fuel vehicles can lead to a significant reduction in GHG emissions. Moreover, a simulated annealing algorithm is adopted to solve large instances of this problem. The performance of the proposed algorithm is evaluated on some random instances.

Management effects on net ecosystem carbon and GHG budgets at European crop sites

Ceschia, Eric; Bêziat, P; Dejoux, J.F.

2010-01-01

The greenhouse gas budgets of 15 European crop sites covering a large climatic gradient and corresponding to 41 site-years were estimated. The sites included a wide range of management practices (organic and/or mineral fertilisation, tillage or ploughing, with or without straw removal....... The variability of the different terms and their relative contributions to the net ecosystem carbon budget (NECB) were analysed for all site-years, and the effect of management on NECB was assessed. To account for greenhouse gas (GHG) fluxes that were not directly measured on site, we estimated the emissions...... caused by field operations (EFO) for each site using emission factors from the literature. The EFO were added to the NECB to calculate the total GHG budget (GHGB) for a range of cropping systems and management regimes. N2O emissions were calculated following the IPCC (2007) guidelines, and CH4 emissions...

The production of biofuels as alternative energy source over fossil fuels has gained immense interest over the years as it can contribute significantly to reduce the greenhouse gas (GHG) emissions from energy production and utilization. Also with rapidly increasing fuel price and fall in oil wells, the present scenario forces us to look for an alternative source of energy that will help us in the operation of industrial as well as the transportation sector. The pulp mills in India are one of the many options. The pulp mills in India can help us to produce bio-fuels by thermo-chemical/biochemical conversion of black liquor and wood residues. These technologies include extraction of hemi-cellulose from wooden chips and black liquor, lignin from black liquor, methanol from evaporator condensates, biogas production from waste sludge, syngas production from biomass using gasification and bio-oil production from biomass using pyrolysis. The objective of this paper is to overview these emerging bio-refinery technologies that can be implemented in Indian Forest Industry to get bio-fuels, bio-chemicals and bio-energy to reduce GHG emissions.

International Nuclear Information System (INIS)

Le Doan Phac; Nguyen Tien Nguyen; Le Van Hong; Nguyen Huu Thanh; Nguyen Anh Tuan

2000-01-01

The Government of Viet Nam has recently formulated a national energy programme entitled Strategy and Policy of Sustainable Energy Development. Its aim is to define a development policy for the country for the period from 2000 to 2020. The main objectives of the national energy programme are: 1. Increasing energy efficiency and demand side management (DSM) 2. Expanding rural electrification 3. Defining an energy price policy (e.g. pricing such that revenues cover costs) 4. Minimizing environmental impacts 5. Encouraging private investment in the energy and electricity sectors 6. Energy supply security 7. Diversifying energy sources, and 8. Exploring the potential role of nuclear power in Viet Nam. In formulating this programme, one of the objectives has been to minimize environmental impacts, including those caused by the electricity sector. Nevertheless, the shortage of investment capital in Viet Nam and the difficulty of securing favourable financial arrangements are crucial obstacles to the introduction of new technology options to mitigate GHG emissions. Viet Nam views CDM as an opportunity to find ways to overcome such problems and expects that all GHG mitigating technologies will be considered equally under the CDM

2017-07-01

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.

Full Text Available Greenhouse gases are one of the main factors that influence the Earth's global temperature variation. As the result of both the beginning of the industrial revolution (the 1750’s and the intensificication and diversification of human activities, the volume of greenhouse gasses increases significantly. The risk of an accelerated global warming can be decreased by reducing the volume of greenhouse gasses emissions resulting from human activities. The annual volume of these emissions is reflected by the Greenhouse gas (GHG indicator. This work carries out a classification of EU countries on the basis of the evolution of the GHG indicator using Partitioning Around Medoids (PAM method.

How international is internationally collaborated research? A bibliometric study of Russian surname holder collaboration networks

Energy Technology Data Exchange (ETDEWEB)

Karaulova, M.; Goek, A.; Shapira, P.

2016-07-01

International research performance indicators attain increased attention in science policy. They are seen to reflect relative competitiveness of a country in producing leading research (in terms of cited papers) and its commercialisation (in terms of assigned patents). However, more studies point to ongoing global bias in production, composition and assessment of research performance metrics (Rafols et al., 2012; van Leeuwen et al., 2001). As research performance indicators are used increasingly in national science policy and in influential international rankings, it is important to understand their inherent bias. For instance, explosive growth of international collaboration in science is widely reported (Glänzel, 2001), and is generally perceived as having beneficial ‘knowledge exchange’ effect for involved parties. It is recognised as a capacity-building factor of domestic research indicating the increase in research quality (Bornmann et al., 2015). However, existing research has reported reproduction of uneven global relations between countries in terms of science and technology. For example, patterns of international cooperation in nanotechnology are still centred on the developed countries, which are key nodes in international networks (Shapira and Wang, 2010). (Author)

2009-03-01

Nursing research in Mainland China is divided into two parts: domestic nursing research, comprising all publications in Chinese; and international nursing research, comprising all publications in English. Domestic nursing research has been developing rapidly, demonstrated by the increase in new national or regional journals and publications. However, little is known about the extent of international research. To outline the development of international nursing research publications in Mainland China and to provide suggestions for future development. All of the papers were retrieved from PubMed. The key search phase was 'China or P.R.China NOT Hong Kong NOT Taiwan NOT Macao [AD]', with the limits of 'English', 'nursing journals' as well as the published date up to '2007/09/30'. PubMed recorded 57 English papers that were originally conducted in Mainland China during the search period from 1989 to 30 September 2007. Thirty-seven of the total 57 (65%) publications were contributed by Beijing, Shanghai and Hubei. Forty-four of the 57 publications were conducted with collaborators from Hong Kong, the USA, the UK and Canada. Thirteen publications were funded by international societies, while only three were funded by the Chinese government. The research topics mainly focused on clinical research, nursing education and nursing management. This study indicates that international nursing research has been growing slowly in Mainland China along with provincial variations. The suggestions to improve nursing research include the reform of nursing education, the enhancement of the collaboration with the international societies and the establishment of research priorities.

Sensitivity of Technical Choices on the GHG Emissions and Expended Energy of Hydrotreated Renewable Jet Fuel from Microalgae

Patouillard Laure

2016-01-01

Full Text Available Taking into account the environmental impacts of biofuel production is essential to develop new and innovative low-emission processes. The assessment of life cycle GreenHouse Gas (GHG emissions of biofuel is mandatory for the countries of the European Union. New biomass resources that hardly compete with food crops are been developed increasingly. Microalgae are an interesting alternative to terrestrial biomass thanks to their high photosynthetic efficiency and their ability to accumulate lipids. This article provides an analysis of potential environmental impacts of the production of algal biofuel for aviation using the Life Cycle Assessment (LCA. Evaluated impacts are GHG emissions and the primary energy consumption, from extraction of raw materials to final waste treatment. This study compared two management choices for oilcakes generated after oil extraction from microalgae. In the first system, these cakes are treated by energetic allocation and in the second by anaerobic digestion. In both cases, the steps of cultivation and harvesting have the highest impact on the results. Sensitivity analyzes are performed on technical choices of operating systems (choice of the type of nutrients, mode of harvesting, drying and oil extraction as well as a Monte-Carlo analysis on key parameter values for GHG emissions (concentration of microalgae in ponds, productivity and oil content. The results highlight the impact of the use of chemical fertilizers and the importance of the concentration of algae on GHG emissions and energy consumption.

Modern International Research Groups: Networks and Infrastructure

In a globalized economy, education and research are becoming increasing international in content and context. Academic and research institutions worldwide try to internationalize their programs by setting formal or informal collaborations. An education that is enhanced by international experiences leads to mobility of the science and technology workforce. Existing academic cultures and research structures are at odds with efforts to internationalize education. For the past 20-30 years, the US has recognized the need to improve the abroad experience of our scientists and technologists: however progress has been slow. Despite a number of both federally and privately supported programs, efforts to scale up the numbers of participants have not been satisfactory. The exchange is imbalanced as more foreign scientists and researchers move to the US than the other way around. There are a number of issues that contribute to this imbalance but we could consider the US academic career system, as defined by its policies and practices, as a barrier to internationalizing the early career faculty experience. Strict curricula, pre-tenure policies and financial commitments discourage students, post doctoral fellows and pre-tenure faculty from taking international leaves to participate in research abroad experiences. Specifically, achieving an international experience requires funding that is not provided by the universities. Furthermore, intellectual property requirements and constraints in pre-tenure probationary periods may discourage students and faculty from collaborations with peers across the Atlantic or Pacific or across the American continent. Environments that support early career networking are not available. This presentation will discuss the increasing need for international collaborations and will explore the need for additional programs, more integration, better conditions and improved infrastructures that can encourage and support mobility of scientists.

The mechanisms regulating peat decomposition and C carbon storage in peatlands are poorly understood, particularly with regard to the importance of the biochemical compounds produced by different plant species and in turn peat quality controls on C storage and GHG flux. To examine the role of carbon quality in C accretion in northern compared to tropical peatlands we completed field and lab studies on bog peats collected in Minnesota, North Carolina, Florida and Peru to answer three fundamental questions; 1) is tropical peat more recalcitrant than northern peat 2) does the addition of aromatic and phenolic C compounds increase towards the tropics 3) do differences in the chemical structure of organic matter explain variances in carbon storage and GHG flux in tropical versus northern peatlands? Our main hypothesize is that high concentrations of phenolics and aromatic C compounds produced in shrub and tree plant communities in peatlands coupled with the fire production of biochar aromatics in peatlands may provide a dual biogeochemical latch mechanism controlling microbial decomposition of peat even under higher temperatures and seasonal drought. By comparing the peat bog soil cores collected from the MN peat bogs, NC Pocosins, FL Everglades and Peru palm swamps we find that the soils in the shrub-dominant Pocosin contain the highest phenolics, which microbial studies indicate have the strongest resistance to microbial decomposition. A chemical comparison of plant driven peat carbon quality along a north to south latitudinal gradient indicates that tropical peatlands have higher aromatic compounds, and enhanced phenolics, especially after light fires, which enhances C storage and affect GHG flux across the latitudinal gradient.

Internal combustion engine run on biogas is a potential solution to meet Indonesia emission target

Science.gov (United States)

Ambarita, Himsar

2017-09-01

Indonesia has released two different Greenhouse Gas (GHG) emissions reduction targets. The first target, released in 2009, is reduction GHG emissions 26% from Business-as-Usual (BAU) level using own budget and up 41% if supported international aids by 2020. The second target is reduction 29% and 41% from BAU by 2030 using own budget and with international support, respectively. In this paper, the BAU emissions and emissions reduction target of these two targets are elaborated. In addition, the characteristics of emissions from transportation sector are discussed. One of the potential mitigation actions is switching fuel in transportation sector. The results the most promising mitigation action in the transportation is switching oil fuel with biofuel. The Government of Indonesia (GoI) focuses on using biodiesel and bioethanol to run internal combustion engine in transportation sector and biogas is aimed to fuel power plant unit. However, there is very limited of success stories on using biogas in the power plant. The barriers and challenges will be discussed here. It is suggested to run internal combustion engine with biogas.

Increasing the use of energy inputs in agricultural section has been led to numerous environmental concerns such as greenhouse gas (GHG) emissions, high consumption of non-renewable resources, loss of biodiversity and environment pollutions. The study was aimed to analyze the energy use efficiency (EUE) and estimation of GHG emissions from rainfed–based canola production systems (RCPSs) in Iran. In this study, data were collected from 35 farms in Golestan province (northeast of Iran) by a face to face questionnaire performed and statistical yearbooks of 2014. The amount of GHG emissions (per hectare) from inputs used in RCPSs was calculated using CO 2 emissions coefficient of agricultural inputs. Results showed that the EUE and net energy (NE) were as 3.44 and 35,537.81 MJ ha −1 , respectively. The value of these indices for the study area indicated that surveyed fields are approximately efficient in the use of energy for canola production. The highest share of energy consumption belonged to nitrogen fertilizer (42.09%) followed by diesel fuel (39.81%). In production of rainfed canola, GHG emission was estimated as 1009.91 kg CO 2 equivalent per hectare. Based on the results, nitrogen fertilizer (44.15%), diesel fuel (30.16%) and machinery (14.49%) for field operations had the highest share of GHG emission. The total consumed energy by inputs could be classified as direct energy (40.09%), and indirect energy (59.91%) or renewable energy (2.02%) and nonrenewable energy (97.98%). These results demonstrate that the share of renewable energies in canola production is very low in the studied region and agriculture in Iran is very much dependent on non-renewable energies. In this study, the energy use status in RCPSs has analyzed and the main involved causes have been interpreted. - Highlights: • Fertilizers had the highest share in GHG emission. • The share of renewable energy was low in canola production. • Canola production is efficient in Iran.

Lin, Tao; Xu, Xin

2017-04-01

Bidding competition of international projects is more and more fierce currently. However, China started late relatively in the field, it is still lack of experience in the aspect of participation in bidding of international projects, and more effective bidding quotation system is not formed till present. Therefore, China can not win through systemic bidding quotation methods compared with many powerful bidding enterprises in the international field. Research on the field is also focused by many aspects as a result. It is urgent to solve related problems. Game theory is combined for analyzing the effectiveness and operability of bidding quotation models mainly based on current situation of bidding market in China international projects during research process in the paper. The research starts with the perspective of bidders for analyzing their game with tenderers and other bidders. The results have operational value aiming at bidders.

[Basic research in ophthalmology in Germany and its international context].

Schlötzer-Schrehardt, U; Cursiefen, C

2017-09-01

Experimental basic research provides the foundations for the elucidation of pathophysiological mechanisms of diseases and the development of novel diagnostic and therapeutic strategies for ophthalmological diseases. The objective of this contribution is to provide an overview of the international interconnection of basic research in ophthalmology in Germany. The international context of ophthalmological research conducted in Germany is presented by means of personal experiences and data published by the German Ophthalmological Society (DOG), the German Research Foundation (DFG) and the European Union (EU). Due to the lack of organized databases this article lays no claim to completeness. Basic research in ophthalmology in Germany is mainly conducted in university eye departments and is mainly related to the etiology, pathophysiology and therapy development for various ophthalmic diseases. It is primarily funded by the DFG, the Federal Ministry of Education and Research (BMBF) and the EU plays an increasingly important role. Thus, ophthalmological research is integrated into numerous European research networks and beyond that into many international interconnections and relationships. In Germany, both clinical and basic research in ophthalmology is integrated into many international networks and is only functionally viable in an international context; however, given the increasing impact of ophthalmological research in Asian countries, future strategies require a continued focus on career development, research infrastructure, working environment and international cooperation.

Greenhouse gas emissions from hydropower. The state of research in 1996

Gagnon, L.; Vate, J.F. van de

1997-01-01

This paper reports on the findings of a recent IAEA expert meeting on the assessment of greenhouse gas (GHG) emissions from the full 'lifecycle' of hydropower. It discusses the different categories of hydropower plants in view of the two main sources of GHG emissions: first, direct and indirect emissions associated with the construction of the plants; second, emissions from decaying biomass from land flooded by hydro reservoirs. In terms of GHG emissions, this paper shows that, in most cases, hydropower is a good alternative to fossil fuelled power generation. For hydropower plants in cold climate, a typical GHG emission factor is 15 g CO 2 equivalent/kWh, which is 30-60 times less than the factors of usual fossil fuel generation. For some hydropower plants in tropical climates, theoretical calculations have shown that reservoir emissions could be very high. However, no measurements of emission were taken from tropical reservoirs and the current level of research does not allow for a reliable evaluation. Research is urgently needed in humid tropical climates. (author)

CAP payments and agricultural GHG emissions in Italy. A farm-level assessment.

Science.gov (United States)

Coderoni, Silvia; Esposti, Roberto

2018-06-15

The Common Agricultural Policy (CAP) is an important external driver of European agricultural production. Nowadays and in its envisioned future structure post-2020, the CAP has among its major objectives tackling climate change, for what concerns both adaptation and mitigation strategies. However, little is known about the link between past CAP reforms and agricultural greenhouse gases (GHG) emissions. This paper investigates the possible role played by the Fischler Reform (FR) on the agricultural GHG emissions at the farm level. The FR represents a major CAP reform for which data availability allows an ex-post analysis about its actual impacts. The empirical analysis concerns a balanced panel of 6542 Italian Farm Accountancy Data Network observed over years the 2003-2007. Multinomial Logit models are estimated in sequence to express how the farm-level production choices, and the respective emissions, vary over time also in response to CAP expenditure. Results suggest that CAP expenditure had a role in the evolution of the farm-level emissions, though the direction of this effect may differ across farms and deserves further investigation.

Global environmental problems such as climate change are not bounded by national borders or scientific disciplines, and therefore require international, interdisciplinary teamwork to develop understandings of their causes and solutions. Interdisciplinary scientific work is difficult enough, but these challenges are often magnified when teams also work across national boundaries. The literature on the challenges of interdisciplinary research is extensive. However, research on international, interdisciplinary teams is nearly non-existent. Our objective is to fill this gap by reporting on results from a study of a large interdisciplinary, international National Science Foundation Partnerships for International Research and Education (NSF-PIRE) research project across the Americas. We administered a structured questionnaire to team members about challenges they faced while working together across disciplines and outside of their home countries in Argentina, Brazil, and Mexico. Analysis of the responses indicated five major types of barriers to conducting interdisciplinary, international research: integration, language, fieldwork logistics, personnel and relationships, and time commitment. We discuss the causes and recommended solutions to the most common barriers. Our findings can help other interdisciplinary, international research teams anticipate challenges, and develop effective solutions to minimize the negative impacts of these barriers to their research.

GHG sustainability compliance of rapeseed-based biofuels produced in a Danish multi-output biorefinery system

International Nuclear Information System (INIS)

Boldrin, Alessio; Astrup, Thomas

2015-01-01

Biofuels are likely to play an increasingly important role in the transportation sector in the coming decades. To ensure the sustainability of the biofuel chain, regulatory criteria and reduction targets for greenhouse gases (GHG) emissions have been defined in different legislative frameworks (e.g. the European Renewable Energy Directive, RED). The provided calculation methods, however, leave room for interpretation regarding methodological choices, which could significantly affect the resulting emission factors. In this study, GHG reduction factors for a range of biofuels produced in a Danish biorefinery system were determined using five different emission allocation principles. The results show that emission savings ranged from −34 % to 71 %, indicating the need for a better definition of regulatory calculation principles. The calculated emission factors differed significantly from default values provided in the literature, suggesting that case-specific local conditions should be taken into consideration. A more holistic LCA-based approach proved useful in overcoming some of the issues inherent in the regulatory allocation principles. On this basis, indirect land use change (ILUC) emissions were shown to have the same magnitude as the direct emissions, thus indicating that the overall system should be included when assessing biofuel sustainability criteria. - Highlights: • Fulfillment of the GHG compliance criteria may depend on the calculation criteria. • Default factors may not be representative of local conditions. • Zero burden approach should be excluded. • ILUC should not be neglected

FUTURE FOSSIL FUEL PRICE IMPACTS ON NDC ACHIEVEMENT; ESTIMATION OF GHG EMISSIONS AND MITIGATION COSTS

Directory of Open Access Journals (Sweden)

Yosuke Arino

2017-12-01

Full Text Available The Shale Revolution in the US, a supply-side innovation in oil and gas production, has been dramatically changing the world’s fossil fuel energy markets – leading to a decrease in oil, gas and coal prices. Some projections suggest that low fossil fuel prices might continue at least over the next few decades. Uncertainty in fossil fuel prices might affect the levels of emission reductions expected from submitted nationally determined contributions (NDCs and/or influence the difficulty of achieving the NDCs. This paper evaluated the impact of different (high, medium, and low fossil fuel prices, sustained through to 2050, on worldwide GHG emissions reductions and associated costs (mainly marginal abatement costs (MACs. Total global GHG emissions were estimated to be 57.5-61.5 GtCO2eq by 2030, with the range shown reflecting uncertainties about fossil fuel prices and the target levels of several NDCs (i.e., whether their upper or lower targets were adopted. It was found that lower fuel prices not only diminished the environmental effectiveness of global NDCs but also widened regional differences of marginal and total abatement costs, thereby generating more room for carbon leakage. One possible policy direction in terms of abatement efficiency, fairness and environmental effectiveness would be to require countries with low marginal and total abatement costs but having a major influence on global GHG emissions (such as China and India to increase their mitigation efforts, especially in a low-fuelprice world.

Analyzing the Effects of Car Sharing Services on the Reduction of Greenhouse Gas (GHG Emissions

Directory of Open Access Journals (Sweden)

Jiyeon Jung

2018-02-01

Full Text Available This study examines the environmental impacts of roundtrip car sharing services by investigating transportation behavior. Car sharing should contribute to reduced greenhouse gas GHG emissions; however, such schemes include both positive and negative environmental effects, including: (1 reduced CO2e (carbon dioxide equivalent from substituting private vehicle use for more fuel-efficient car sharing vehicles, (2 increased CO2e as car-less individuals switch from public transit to car sharing vehicles and (3 reduced CO2e due to fewer vehicles. This study examines the impacts of this modal shift on greenhouse gas (GHG emissions using three types of models: a mixed logit model to analyze car sharing service preferences; a binary logit model to analyze whether individuals are willing to forgo vehicle ownership or planned purchases to use car sharing services; and a linear regression to determine how much private vehicle or public transportation use would be replaced by car sharing and the resulting effects on mobility. Total emissions from the current car sharing market equal 1,025,589.36 t CO2e/year. However, an increase in electric vehicle (EV charging stations to 50% of the number of gasoline-fuel stations would increase the probability of electric car sharing vehicle use, thereby reducing emissions by 655,773 t CO2e. This study shows that forgoing vehicle purchases does not offset the increased GHG emissions caused by the shift from public transportation or private vehicle use to car sharing.

2011-04-01

Full Text Available Our objective was to compare and evaluate the practical applicability to REDD+ of ten forest management, social, environmental and carbon standards that are currently active worldwide: Climate, Community and Biodiversity (CCB, CCB REDD+ Social and Environmental Standards (CCBA REDD+ S&E, CarbonFix Standard (CFS, Forest Stewardship Council (FSC, Global Conservation Standard (GCS, ISO 14064:2006, Plan Vivo Standard, Programme for Endorsement of Forest Certification (PEFC, SOCIALCARBON Standard and the Voluntary Carbon Standard (VCS. We developed a framework for evaluation of these standards relative to each other using four substantive criteria: (1 poverty alleviation, (2 sustainable management of forests (SMF, (3 biodiversity protection, (4 quantification and assessment of net greenhouse gas (GHG benefits; and two procedural criteria: (5 monitoring and reporting, and (6 certification procedures. REDD programs require assessment of GHG benefits, monitoring, reporting and certification. Our analysis shows that only the Voluntary Carbon Standard (VCS treats these three criteria comprehensively. No standard provides comprehensive coverage of the social and other environmental criteria. FSC, PEFC and CarbonFix provide comprehensive assessments of the sustainable forest management criterion. CCBA REDD+ S&E, CCB, and GCS provide comprehensive coverage of the biodiversity and poverty alleviation criteria. Experience in using these standards in pilot projects shows that projects are currently combining several standards as part of their strategy to improve their ability to attract investment, but costs of implementing several certification schemes is a concern. We conclude that voluntary certification provides useful practical experience that should feed into the design of the international REDD+ regime.

Full text: The first scientific research and educational institution to be set up on a completely international basis was officially inaugurated in Trieste on 5 October 1964 by the Director General of IAEA, Dr. Sigvard Eklund, when he opened the first seminar of the International Centre for Theoretical Physics. As evidence of the international nature of the institution he noted that the scientists who would work and teach there during the first year represented sixteen different countries. By the end of 1964, the Centre building was nearing completion and three of the five floors were occupied. A successful symposium had been held on the subject of plasma physics, and a score of professors and fellows were at work, from Bulgaria, Czechoslovakia, Greece, India, Japan, Jordan, the Netherlands, Norway, Pakistan, Poland, the United Kingdom, and the United States. A dozen scientific papers had been issued as preprints. The main purpose of the Centre is to foster the advancement of theoretical physics through training and research; at first the chief subject will be high-energy and elementary particle physics. Plasma physics, low energy physics and solid-state physics will also be dealt with. Special attention is paid to the needs of the developing countries. Of the 25 fellows selected for the academic year 1964-65, more than half are from South America, Africa and Asia. In conjunction with the Research Centre, there is an Advanced School for theoretical Physics to provide graduate training for fellows who need such preparation before they embark upon research. The Centre works under the guidance of a Scientific Council comprising the president, Prof. M. Sandoval-Vallarta (Nuclear Energy Commission of Mexico); Prof. A. Abragam (Saclay, France); Prof. R. Oppenheimer (Institute for Advanced Study, Princeton, USA); Dr. V. Soloviev (Dubna, USSR); Prof V.F. Weiskopf (Director General, CERN) ; Prof Abdus Salam (Imperial College, London) ; Prof. P.

International collaboration between nuclear research centres and the role of research reactors

International Nuclear Information System (INIS)

Dodd, B.

2001-01-01

A research reactor is a core facility in many nuclear research centres (NRCs) of Member States and it is logical that it should be the focus of any international collaboration between such centres. There are several large and sophisticated research reactors in operation in both developed and developing Member States, such as Belgium, China, Egypt, France, Hungary, Indonesia, India, Japan, ROK, Netherlands, South Africa and the USA. There are also several new, large reactors under construction or being planned such as those in Australia, Canada, China, France, Germany, and Thailand. It is felt that the utilization of these reactors can be enhanced by international co-operation to achieve common goals in research and applications. (author)

Biomass direct-fired power generation system in China: An integrated energy, GHG emissions, and economic evaluation for Salix

International Nuclear Information System (INIS)

Wang, Changbo; Zhang, Lixiao; Chang, Yuan; Pang, Mingyue

2015-01-01

To gain a better understanding of the options of biomass power generation in China, this study presented an integrated energy, environmental, and economic evaluation for Salix in China, and a typical Salix direct-fired power generation system (SDPGS) in Inner Mongolia was selected for case study. A tiered hybrid life cycle assessment (LCA) model was developed to calculate the “planting-to-wire” (PTW) energy consumption, greenhouse gas (GHG) emissions, and economic cost and profit of the SDPGS, including feedstock cultivation, power plant construction and operation, and on-grid price with/without government subsidies. The results show that the PTW energy consumption and GHG emissions of Salix are 0.8 MJ/kWh and 114 g CO 2 -eq/kWh, respectively, indicating an energy payback time (EPBT) of 3.2 years. The SDPGS is not economically feasible without government subsidies. The PTW costs are dominated by feedstock cultivation. The energy saving and GHG mitigation benefits are still robust, even when the power plant runs at only 60% design capacity. For future development of biomass power in China, scientific planning is necessary to guarantee a sufficient feedstock supply. In addition, technology progress, mature industrial chains, and reasonable price setting policy are required to enable potential energy and environmental advantages of biomass power moving forward. -- Highlights: •A hybrid LCA model was used to evaluate overall performance of the SDPGS. •On-site processes dominate the “planting-to-wire” footprints. •The energy saving and GHG mitigation benefits of the SDPGS are robust. •The economic profit of the SDPGS is feeble without government subsidies. •Generating efficiency promotion has a comprehensive positive effect on the system

Forest biomass supply chains in Ireland: A life cycle assessment of GHG emissions and primary energy balances

International Nuclear Information System (INIS)

Murphy, Fionnuala; Devlin, Ger; McDonnell, Kevin

2014-01-01

Highlights: • Wood energy supply chains are analysed for energy requirements and GHG emissions. • Use of residues and stumps for energy is evaluated for Irish conditions. • Results highlight transportation as the most energy and GHG emission intensive step. • Wood energy compares favourably with other biomass sources and fossil fuels. - Abstract: The demand for wood for energy production in Ireland is predicted to double from 1.5 million m 3 over bark (OB) in 2011 to 3 million m 3 OB by 2020. There is a large potential for additional biomass recovery for energetic purposes from both thinning forest stands and by harvesting of tops and branches, and stumps. This study builds on research within the wood-for-energy concept in Ireland by analysing the energy requirements and greenhouse gas emissions associated with thinning, residue bundling and stump removal for energy purposes. To date there have been no studies on harvesting of residues and stumps in terms of energy balances and greenhouse gas emissions across the life cycle in Ireland. The results of the analysis on wood energy supply chains highlights transport as the most energy and greenhouse gas emissions intensive step in the life cycle. This finding illustrates importance of localised production and use of forest biomass. Production of wood chip, and shredded bundles and stumps, compares favourably with both other sources of biomass in Ireland and fossil fuels

Availability of Biomass Residues for Co-Firing in Peninsular Malaysia: Implications for Cost and GHG Emissions in the Electricity Sector

OpenAIRE

W. Michael Griffin; Jeremy Michalek; H. Scott Matthews; Mohd Nor Azman Hassan

2014-01-01

Fossil fuels comprise 93% of Malaysia’s electricity generation and account for 36% of the country’s 2010 Greenhouse Gas (GHG) emissions. The government has targeted the installation of 330 MW of biomass electricity generation capacity by 2015 to avoid 1.3 Mt of CO 2 emissions annually and offset some emissions due to increased coal use. One biomass option is to co-fire with coal, which can result in reduced GHG emissions, coal use, and costs of electricity. A linear optimization cost model wa...

Does consideration of GHG reductions change local decision making? A Case Study in Chile

Science.gov (United States)

Cifuentes, L. A.; Blumel, G.

2003-12-01

While local air pollution has been a public concern in developing countries for some time, climate change is looked upon as a non-urgent, developed world problem. In this work we present a case study of the interaction of measures to abate air pollution and measures to mitigate GHG emissions in Santiago, Chile, with the purpose of determining if the consideration of reductions in GHG affects the decisions taken to mitigate local air pollution. The emissions reductions of both GHG and local air pollutants were estimated from emission factors (some derived locally) and changes in activity levels. Health benefits due to air pollution abatement were computed using figures derived previously for the cost benefit analysis of Santiago's Decontamination Plan, transferred to the different cities taking into consideration local demographic and income data. The Santiago estimates were obtained using the damage function approach, based on some local epidemiological studies, and on local health and demographic data. Unit social values for the effects were estimated locally (for cost of treatment and lost productivity values) or extrapolated from US values (mainly for WTP values) using the ratio of per-capita income and an income elasticity of 1. The average benefits of emission abatement (in 1997 US\\ per ton) are 1,800 (1,200-2300) for NOx, 3,000 (2,100-3900) for SO2, 31,900 (21,900 - 41,900) for PM, and 630 (430 - 830) for resuspended dust. Economic benefits due to carbon reduction were considered at 3.5, 10 and 20 UStCO2. Marginal abatement cost curves were constructed considering private and net costs (private less the potential sales of carbon credits) Due to the bottom-up approach to constructing the marginal cost curve, many abatement measures (like congestion tolls and CNG instead of diesel buses) amounting to 8% reduction of PM2.5 concentration, exhibit a negative private cost. If the health benefits are considered for the decision, a maximum reduction of 22% in PM2

Developing an optimal energy supply strategy for Syria in view of GHG reduction with least-cost climate protection

International Nuclear Information System (INIS)

Hainoun, A.; Omar, H.; Almoustafa, A.; Seif Al-din, M.Kh.

2010-12-01

This report presents the outcomes of a two years CRP project entitled (Developing an optimal energy supply strategy for Syria in view of GHG reduction with least-cost climate protection). The main activity deals with a case study concerning the assessment of optimal Syrian energy supply strategy taking into account the impact of environmental constraints related to GHG reduction on the cost and prospects of energy sources and technologies with special emphasis on renewable and nuclear options. In a previous activity the future long-term development of Syrian energy and electricity demand has been analyzed according to various scenarios of socio-economic and technological development of the country. The results indicate that energy demand will grow rapidly in the next decades as consequent of many socio-economic and technological factors given by Syria's high population growth, its current economic transition, and its expected economic and technological development, particularly in the industry sector. To meet the projected future energy demand up to 2030, an optimal reference energy supply strategy with minimal supply cost has been developed taking into account, in particular, the availability of national energy resources and diversity of supply options. The analysis has been performed using the IAEA's optimization tool MESSAGE. MESSAGE is suitable to formulate and evaluate alternative energy supply strategies consistent with pre-defined constraints including limits on new investment, fuel availability and trade, environmental regulations, and market penetration rates for new technologies. To evaluate the potential of GHG reduction in the Syrian power sector an alternative energy supply scenario - Mitigation Scenario (Ren S ce) has been introduced reflecting the most probable adaptation measures of this sector to mitigate GHG emission by more dependency on renewable options. Compatible with the Kyoto agreement for developing countries, the CDM is being considered

With the assembly of the International Space Station (ISS) nearing completion and the support of a full-time crew of six, a new era of utilization for research is beginning. For more than 15 years, the ISS international partnership has weathered financial, technical and political challenges proving that nations can work together to complete assembly of the largest space vehicle in history. And while the ISS partners can be proud of having completed one of the most ambitious engineering projects ever conceived, the challenge of successfully using the platform remains. During the ISS assembly phase, the potential benefits of space-based research and development were demonstrated; including the advancement of scientific knowledge based on experiments conducted in space, development and testing of new technologies, and derivation of Earth applications from new understanding. The configurability and human-tended capabilities of the ISS provide a unique platform. The international utilization strategy is based on research ranging from physical sciences, biology, medicine, psychology, to Earth observation, human exploration preparation and technology demonstration. The ability to complete follow-on investigations in a period of months allows researchers to make rapid advances based on new knowledge gained from ISS activities. During the utilization phase, the ISS partners are working together to track the objectives, accomplishments, and the applications of the new knowledge gained. This presentation will summarize the consolidated international results of these tracking activities and approaches. Areas of current research on ISS with strong international cooperation will be highlighted including cardiovascular studies, cell and plant biology studies, radiation, physics of matter, and advanced alloys. Scientific knowledge and new technologies derived from research on the ISS will be realized through improving quality of life on Earth and future spaceflight endeavours

Life-cycle environmental and economic impacts of energy-crop fuel-chains: an integrated assessment of potential GHG avoidance in Ireland

International Nuclear Information System (INIS)

Styles, David; Jones, Michael B.

2008-01-01

This paper combines life-cycle analyses and economic analyses for Miscanthus and willow heat and electricity fuel-chains in Ireland. Displaced agricultural land-uses and conventional fuels were considered in fuel-chain permutations. Avoided greenhouse gas (GHG) emissions ranged from 7.7 to 35.2 t CO 2 eq. ha -1 a -1 . Most fuel-chain permutations exhibited positive discounted financial returns, despite losses for particular entities at a farm-gate processed-biomass price of Euro 100 t -1 dry-matter. Attributing a value of Euro 10 t -1 CO 2 eq. to avoided GHG emissions, but subtracting financial returns associated with displaced fuel supplies, resulted in discounted annual national economic benefits (DANEBs) ranging from -457 to 1887 Euro ha -1 a -1 . Extrapolating a plausible combination of fuel-chains up to a national indicative scenario resulted in GHG emission avoidance of 3.56 Mt CO 2 eq. a -1 (5.2% of national emissions), a DANEB of 167 M Euro , and required 4.6% of national agricultural land area. As cost-effective national GHG avoidance options, Miscanthus and willow fuel-chains are robust to variation in yields and CO 2 price, and appear to represent an efficient land-use option (e.g. compared with liquid biofuel production). Policies promoting utilisation of these energy-crops could avoid unnecessary, and environmentally questionable, future purchase of carbon credits, as currently required for national Kyoto compliance

Potential options to reduce GHG emissions in Venezuela

Energy Technology Data Exchange (ETDEWEB)

Pereira, N.; Bonduki, Y.; Perdomo, M.

1996-12-31

The Government of Venezuela ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December, 1994. The Convention requires all parties to develop and publish national inventories of anthropogenic greenhouse gas emissions (GHG) as well as national plans to reduce or control emissions, taking into account their common but differentiated responsibilities and their specific national and regional development priorities, objectives, and circumstances. Within this context, the Ministry of Environment and Renewable Natural Resources and the Ministry of Energy and Mines developed the `Venezuelan Case-Study to Address Climate Change`. The study was initiated in October 1993, with the financial and technical assistance of the Government of United States, through the U.S. Country Studies Program (USCSP), and the Global Environment Facility (GEF), through the United Nations Environment Programme (UNEP).

Full GHG balance of drained fen peatland cropped to spring barley and reed canary grass using comparative assessment of CO2 fluxes

2015-01-01

Empirical greenhouse gas (GHG) flux estimates from diverse peatlands are required in order to derive emission factors for managed peatlands. This study on a drained fen peatland quantified the annual GHG balance (Carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and C exported in crop yield......) from spring barley (SB) and reed canary grass (RCG) using static opaque chambers for GHG flux measurements and biomass yield for indirectly estimating gross primary production (GPP). Estimates of ecosystem respiration (ER) and GPP were compared with more advanced but costly and labor-intensive dynamic...... by static chamber and dynamic chamber methods was similar, particularly when using nonlinear regression techniques for flux calculations. A comparison of GPP derived from aboveground biomass and from measuring net ecosystem exchange (NEE) showed that GPP estimation from biomass might be useful, or serve...

Brazilian science communication research: national and international contributions.

Barata, Germana; Caldas, Graça; Gascoigne, Toss

2017-08-31

Science communication has emerged as a new field over the last 50 years, and its progress has been marked by a rise in jobs, training courses, research, associations, conferences and publications. This paper describes science communication internationally and the trends and challenges it faces, before looking at the national level. We have documented science communication activities in Brazil, the training courses, research, financial support and associations/societies. By analyzing the publication of papers, dissertations and theses we have tracked the growth of this field, and compared the level of activity in Brazil with other countries. Brazil has boosted its national research publications since 2002, with a bigger contribution from postgraduate programs in education and communication, but compared to its national research activity Brazil has only a small international presence in science communication. The language barrier, the tradition of publishing in national journals and the solid roots in education are some of the reasons for that. Brazil could improve its international participation, first by considering collaborations within Latin America. International publication is dominated by the USA and the UK. There is a need to take science communication to the next level by developing more sophisticated tools for conceptualizing and analyzing science communication, and Brazil can be part of that.

Closing the translation gap for justice requirements in international research.

Bioethicists have long debated the content of sponsors and researchers' obligations of justice in international clinical research. However, there has been little empirical investigation as to whether and how obligations of responsiveness, ancillary care, post-trial benefits and research capacity strengthening are upheld in low- and middle-income country settings. In this paper, the authors argue that research ethics guidelines need to be more informed by international research practice. Practical guidance on how to fulfil these obligations is needed if research groups and other actors are to successfully translate them into practice because doing so is often a complicated, context-specific process. Case study research methods offer one avenue for collecting data to develop this guidance. The authors describe how such methods have been used in relation to the Shoklo Malaria Research Unit's vivax malaria treatment (VHX) trial (NCT01074905). Relying on the VHX trial example, the paper shows how information can be gathered from not only international clinical researchers but also trial participants, community advisory board members and research funder representatives in order to: (1) measure evidence of responsiveness, provision of ancillary care, access to post-trial benefits and research capacity strengthening in international clinical research; and (2) identify the contextual factors and roles and responsibilities that were instrumental in the fulfilment of these ethical obligations. Such empirical work is necessary to inform the articulation of obligations of justice in international research and to develop guidance on how to fulfil them in order to facilitate better adherence to guidelines' requirements.

The survey on the reduction measures against greenhouse effect gases was carried out which was proposed by the IEA-GHG phase 3 program. In Japan, various low emission vehicles (LEV) such as electric, methanol and natural gas vehicles are under rapid development. Like France, cost reduction and preparation of fuel filling stations are urgently necessary for the diffusion of LEVs. In New Zealand, air pollution by automobiles is not essential. The Switzerland government is promoting the diffusion of compact electric vehicles, and inhibits the use of conventional automobiles in some tourist resorts. The California state is leading the world by prescribing the bold regulation for preventing the air from pollution. In particular, the state government put automobile manufacturers under an obligation to produce zero emission vehicles (ZEV, electric vehicle) by 2% of passenger cars and trucks from 1998 and to increase ZEVs up to 10% until 2010. This report also includes two papers concerned, `Forestry management for sustainable development` and `Tropical forestry action plan after five years.` 142 refs., 19 figs., 23 tabs.

Climate-Smart Livestock Systems: An Assessment of Carbon Stocks and GHG Emissions in Nicaragua.

Lucía Gaitán

Full Text Available Livestock systems in the tropics can contribute to mitigate climate change by reducing greenhouse gas (GHG emissions and increasing carbon accumulation. We quantified C stocks and GHG emissions of 30 dual-purpose cattle farms in Nicaragua using farm inventories and lifecycle analysis. Trees in silvo-pastoral systems were the main C stock above-ground (16-24 Mg ha-1, compared with adjacent secondary forests (43 Mg C ha-1. We estimated that methane from enteric fermentation contributed 1.6 kg CO2-eq., and nitrous oxide from excreta 0.4 kg CO2-eq. per kg of milk produced. Seven farms that we classified as climate-smart agriculture (CSA out of 16 farms had highest milk yields (6.2 kg cow-1day-1 and lowest emissions (1.7 kg CO2-eq. per kg milk produced. Livestock on these farms had higher-quality diets, especially during the dry season, and manure was managed better. Increasing the numbers of CSA farms and improving CSA technology will require better enabling policy and incentives such as payments for ecosystem services.

Cofiring versus biomass-fired power plants: GHG (Greenhouse Gases) emissions savings comparison by means of LCA (Life Cycle Assessment) methodology

International Nuclear Information System (INIS)

Sebastian, F.; Royo, J.; Gomez, M.

2011-01-01

One way of producing nearly CO 2 free electricity is by using biomass as a combustible. In many cases, removal of CO 2 in biomass grown is almost the same as the emissions for the bioelectricity production at the power plant. For this reason, bioelectricity is generally considered CO 2 neutral. For large-scale biomass electricity generation two alternatives can be considered: biomass-only fired power plants, or cofiring in an existing coal power plant. Among other factors, two important aspects should be analyzed in order to choose between the two options. Firstly, which is the most appealing alternative if their Greenhouse Gases (GHG) Emissions savings are taken into account. Secondly, which biomass resource is the best, if the highest impact reduction is sought. In order to quantify all the GHG emissions related to each system, a Life Cycle Assessment (LCA) methodology has been performed and all the processes involved in each alternative have been assessed in a cradle-to-grave manner. Sensitivity analyses of the most dominant parameters affecting GHG emissions, and comparisons between the obtained results, have also been carried out.

Scenario analysis on alternative fuel/vehicle for China's future road transport: Life-cycle energy demand and GHG emissions

International Nuclear Information System (INIS)

Ou Xunmin; Zhang Xiliang; Chang Shiyan

2010-01-01

The rapid growth of vehicles has resulted in continuing growth in China's oil demand. This paper analyzes future trends of both direct and life cycle energy demand (ED) and greenhouse gas (GHG) emissions in China's road transport sector, and assesses the effectiveness of possible reduction measures by using alternative vehicles/fuels. A model is developed to derive a historical trend and to project future trends. The government is assumed to do nothing additional in the future to influence the long-term trends in the business as usual (BAU) scenario. Four specific scenarios are used to describe the future cases where different alternative fuel/vehicles are applied. The best case scenario is set to represent the most optimized case. Direct ED and GHG emissions would reach 734 million tonnes of oil equivalent and 2384 million tonnes carbon dioxide equivalent by 2050 in the BAU case, respectively, more than 5.6 times of 2007 levels. Compared with the BAU case, the relative reductions achieved in the best case would be 15.8% and 27.6% for life cycle ED and GHG emissions, respectively. It is suggested for future policy implementation to support sustainable biofuel and high efficient electric-vehicles, and the deployment of coal-based fuels accompanied with low-carbon technology.

For forest-based biomass to become a significant contribution to the United States' energy portfolio, harvesting operations must be physically feasible and economically viable. An assessment of cost, energy and greenhouse gas (GHG) emissions of forest biomass harvesting was conducted. The assessment differentiates harvesting systems by cut-to-length and whole tree; harvest types of 30%, 70%, and 100% cut; and forest types of hardwoods, softwoods, mixed hardwood/softwood, and softwood plantations. Harvesting cost models were developed for economic assessment and life cycle energy and emission assessment was applied to calculate energy and emissions for different harvesting scenarios, considering material and energy inputs (machinery, diesel, etc.) and outputs (GHG emissions) for each harvesting process (felling, forwarding/skidding, etc.). The developed harvesting cost models and the life cycle energy and emission assessment method were applied in Michigan, U.S. using information collected from different sources. A sensitivity analysis was performed for selected input variables for the harvesting operations in order to explore their relative importance. The results indicated that productivity had the largest impact on harvesting cost followed by machinery purchase price, yearly scheduled hours, and expected utilization. Productivity and fuel use, as well as fuel factors, are the most influential environmental impacts of harvesting operations. - Highlights: • Life cycle energy and emissions for forest biomass harvesting operations. • Harvesting cost models were developed for economic assessment. • Productivity had the largest impact on harvesting cost. • Fuel use contributes the most emissions while lubricants contribute the least.

System expansion for handling co-products in LCA of sugar cane bio-energy systems: GHG consequences of using molasses for ethanol production

International Nuclear Information System (INIS)

Nguyen, Thu Lan T.; Hermansen, John E.

2012-01-01

Highlights: → A challenging issue in LCA is how to account for co-products' environmental burdens. → The two most commonly used procedures are system expansion and allocation. → System expansion appears to be more appropriate than allocation. → Indirect land use change is a consequence of diverting molasses from feed to fuel. → The inclusion of land use change worsens the GHG balance of molasses ethanol. -- Abstract: This study aims to establish a procedure for handling co-products in life cycle assessment (LCA) of a typical sugar cane system. The procedure is essential for environmental assessment of ethanol from molasses, a co-product of sugar which has long been used mainly for feed. We compare system expansion and two allocation procedures for estimating greenhouse gas (GHG) emissions of molasses ethanol. As seen from our results, system expansion yields the highest estimate among the three. However, no matter which procedure is used, a significant reduction of emissions from the fuel stage in the abatement scenario, which assumes implementation of substituting bioenergy for fossil-based energy to reduce GHG emissions, combined with a negligible level of emissions from the use stage, keeps the estimate of ethanol life cycle GHG emissions below that of gasoline. Pointing out that indirect land use change (ILUC) is a consequence of diverting molasses from feed to fuel, system expansion is the most adequate method when the purpose of the LCA is to support decision makers in weighing the options and consequences. As shown in the sensitivity analysis, an addition of carbon emissions from ILUC worsens the GHG balance of ethanol, with deforestation being a worst-case scenario where the fuel is no longer a net carbon saver but carbon emitter.

For promotion of nuclear science and engineering research, examinations were made on the possibilities and necessary measures to extend joint research at international level. The present article is a summary of the reports of investigations performed during FY 1986 through 1991 by the Special Committee of the AESJ for Feasibility Study on International Cooperation for Promotion of Nuclear Science and Engineering Research, under contract with Science and Technology Agency of Japan. Background information was collected on the present status of scientific research facilities in US, European and Asian countries on one hand, and on the expectations and prospects of Japanese scientists on the other hand. Based on the analysis of these data, some measures necessary to expand the international cooperation were proposed. It was emphasized that international joint research on a reciprocal basis would be effective in order to strengthen the technological basis of peaceful uses of nuclear energy. Problems to be solved for the new development were also discussed. (author)

Linking international research to global health equity: the limited contribution of bioethics.

Science.gov (United States)

Pratt, Bridget; Loff, Bebe

2013-05-01

Health research has been identified as a vehicle for advancing global justice in health. However, in bioethics, issues of global justice are mainly discussed within an ongoing debate on the conditions under which international clinical research is permissible. As a result, current ethical guidance predominantly links one type of international research (biomedical) to advancing one aspect of health equity (access to new treatments). International guidelines largely fail to connect international research to promoting broader aspects of health equity - namely, healthier social environments and stronger health systems. Bioethical frameworks such as the human development approach do consider how international clinical research is connected to the social determinants of health but, again, do so to address the question of when international clinical research is permissible. It is suggested that the narrow focus of this debate is shaped by high-income countries' economic strategies. The article further argues that the debate's focus obscures a stronger imperative to consider how other types of international research might advance justice in global health. Bioethics should consider the need for non-clinical health research and its contribution to advancing global justice. © 2011 Blackwell Publishing Ltd.

Research Workforce Diversity: The Case of Balancing National versus International Postdocs in US Biomedical Research.

Ghaffarzadegan, Navid; Hawley, Joshua; Desai, Anand

2014-03-01

The US government has been increasingly supporting postdoctoral training in biomedical sciences to develop the domestic research workforce. However, current trends suggest that mostly international researchers benefit from the funding, many of whom might leave the USA after training. In this paper, we describe a model used to analyse the flow of national versus international researchers into and out of postdoctoral training. We calibrate our model in the case of the USA and successfully replicate the data. We use the model to conduct simulation-based analyses of effects of different policies on the diversity of postdoctoral researchers. Our model shows that capping the duration of postdoctoral careers, a policy proposed previously, favours international postdoctoral researchers. The analysis suggests that the leverage point to help the growth of domestic research workforce is in the pregraduate education area, and many policies implemented at the postgraduate level have minimal or unintended effects on diversity.

Life-Cycle Energy and GHG Emissions of Forest Biomass Harvest and Transport for Biofuel Production in Michigan

Directory of Open Access Journals (Sweden)

Fengli Zhang

2015-04-01

Full Text Available High dependence on imported oil has increased U.S. strategic vulnerability and prompted more research in the area of renewable energy production. Ethanol production from renewable woody biomass, which could be a substitute for gasoline, has seen increased interest. This study analysed energy use and greenhouse gas emission impacts on the forest biomass supply chain activities within the State of Michigan. A life-cycle assessment of harvesting and transportation stages was completed utilizing peer-reviewed literature. Results for forest-delivered ethanol were compared with those for petroleum gasoline using data specific to the U.S. The analysis from a woody biomass feedstock supply perspective uncovered that ethanol production is more environmentally friendly (about 62% less greenhouse gas emissions compared with petroleum based fossil fuel production. Sensitivity analysis was conducted with key inputs associated with harvesting and transportation operations. The results showed that research focused on improving biomass recovery efficiency and truck fuel economy further reduced GHG emissions and energy consumption.

The use of Meta-Regression Analysis to harmonize LCA literature: an application to GHG emissions of 2. and 3. generation biofuels

International Nuclear Information System (INIS)

Menten, Fabio; Cheze, Benoit; Patouillard, Laure; Bouvart, Frederique

2013-01-01

This article presents the results of a literature review performs with a meta-regression analysis (MRA) that focuses on the estimates of advanced biofuel Greenhouse Gas (GHG) emissions assessed with a Life Cycle Assessment (LCA) approach. The mean GHG emissions of both second (G2) and third generation (G3) biofuels and the effects of factors influencing these estimates are identified and quantified by means of specific statistical methods. 47 LCA studies are included in the database, providing 593 estimates. Each study estimate of the database is characterized by i) technical data/characteristics, ii) author's methodological choices and iii) typology of the study under consideration. The database is composed of both the vector of these estimates - expressed in grams of CO 2 equivalent per MJ of biofuel (g CO 2 eq/MJ) - and a matrix containing vectors of predictor variables which can be continuous or dummy variables. The former is the dependent variable while the latter corresponds to the explanatory variables of the meta-regression model. Parameters are estimated by mean of econometrics methods. Our results clearly highlight a hierarchy between G3 and G2 biofuels: life cycle GHG emissions of G3 biofuels are statistically higher than those of Ethanol which, in turn, are superior to those of BtL. Moreover, this article finds empirical support for many of the hypotheses formulated in narrative literature surveys concerning potential factors which may explain estimates variations. Finally, the MRA results are used to address the harmonization issue in the field of advanced biofuels GHG emissions thanks to the technique of benefits transfer using meta-regression models. The range of values hence obtained appears to be lower than the fossil fuel reference (about 83.8 in g CO 2 eq/ MJ). However, only Ethanol and BtL do comply with the GHG emission reduction thresholds for biofuels defined in both the American and European directives. (authors)

Sustainable extensification as an alternative model for reducing GHG emissions from agriculture. The case of an extensively managed organic farm in Denmark

DEFF Research Database (Denmark)

Bluwstein, Jevgeniy; Braun, Martin; Henriksen, Christian Bugge

2015-01-01

GHG emissions of an extensively managed Danish organic farm were estimated upstream and on-farm. The results were compared to Danish national levels based on land area and output. Overall, the farm emitted 2.12 t CO2eq ha−1 yr−1. Excluding land use, land use change, and forestry (LULUCF) related...... emissions, the combined GHG emissions from energy- and agriculture-based activities at the case farm were 47% lower (per unit area) and 12% higher (per unit output), than GHG emissions from Danish agriculture. With current livestock density (0.64 LU ha−1) and crop production area, the case study farm would...... supply at average 1,466 kcal per inhabitant per day in Denmark, if the farm was scaled up to Danish national level. With a reduction of livestock density to 0.36 LU ha−1 and proportional cropland area expansion for food production (ceteris paribus), the case study farm could supply around 4,940 kcal...

Status of UFD Campaign International Activities in Disposal Research

While the United States research program for geologic disposal of high-level radioactive waste over the past decades focused solely on an open tunnel emplacement in unsaturated densely fractured tuff, several international organizations have made significant progress in the characterization and performance evaluation of other disposal design options and host rock characteristics, most of which were very different from those studied in the U.S. As a result, areas of direct collaboration between the U.S. Department of Energy’s (DOE) and international geologic disposal programs were quite limited during that time. Recently, the decision by DOE to no longer pursue the geologic disposal of high-level radioactive waste and spent fuel at the Yucca Mountain site has shifted the nation’s focus to disposal design options and geologic environments similar to those being investigated by other nations. DOE started to recognize that close international collaboration is a beneficial and costeffective strategy for advancing disposal science and, in FY12, embarked on a comprehensive effort to identify international collaboration opportunities, to interact with international organizations and advance promising collaborations, and to plan/develop specific R&D activities in cooperation with international partners. This report describes the active collaboration opportunities available to U.S. researchers as a result of this effort, and presents specific cooperative research activities that have been recently initiated within DOE’s disposal research program. The focus in this report is on those opportunities that provide access to field data (and respective interpretation/modeling), and/or may allow participation in ongoing and planned field experiments.

Geophysical research increasingly requires global multidisciplinary approaches and global integration. Global warming, increasing CO2 levels and increased needs of mineral and energy resources emphasize impact of human activities. The planetary view of our Earth as a deeply complex interconnected system also emphasizes the need of international scientific cooperation. International collaboration presents an immense potential and is urgently needed for further development of geosciences research and education. In analyzing international collaboration a relevant aspect is the role of scientific societies. Societies organize meetings, publish journals and books and promote cooperation through academic exchange activities and can further assist communities in developing countries providing and facilitating access to scientific literature, attendance to international meetings, short and long-term stays and student and young researcher mobility. Developing countries present additional challenges resulting from limited economic resources and social and political problems. Most countries urgently require improved educational and research programs. Needed are in-depth analyses of infrastructure and human resources and identification of major problems and needs. Questions may include what are the major limitations and needs in research and postgraduate education in developing countries? what and how should international collaboration do? and what are the roles of individuals, academic institutions, funding agencies, scientific societies? Here we attempt to examine some of these questions with reference to case examples and AGU role. We focus on current situation, size and characteristics of research community, education programs, facilities, economic support, and then move to perspectives for potential development in an international context.

As sources of greenhouse gas (GHG) emissions, integrated urban drainage systems (IUDSs) (i.e., sewer systems, wastewater treatment plants and receiving water bodies) contribute to climate change. This paper, produced by the International Working Group on Data and Models, which works under the IWA/IAHR Joint Committee on Urban Drainage, reviews the state-of-the-art and modelling tools developed recently to understand and manage GHG emissions from IUDS. Further, open problems and research gaps are discussed and a framework for handling GHG emissions from IUDSs is presented. The literature review reveals that there is a need to strengthen already available mathematical models for IUDS to take GHG into account.

National Institute on Drug Abuse International Program: improving opioid use disorder treatment through international research training.

Gust, Steven W; McCormally, Judy

2018-07-01

For more than 25 years, the National Institute on Drug Abuse (NIDA) has supported research-training programs, establishing a global research network and expanding the knowledge base on substance use disorders. International research to inform approaches to opioid addiction is particularly important and relevant to the United States, where opioid misuse, addiction, and overdose constitute an emerging public health crisis. This article summarizes the NIDA International Program and illustrates its impact by reviewing recent articles about treatment approaches for opioid use disorders (OUD). Studies in several countries have demonstrated the effectiveness of physician office-based opioid substitution therapies. Other research has demonstrated the effectiveness of different formulations and doses of the opioid antagonist naltrexone, as well as different approaches to providing naloxone to treat opioid overdose. Continuing research into implementation of evidence-based treatment in international settings with limited resources is applicable to US regions that face similar structural, legal, and fiscal constraints. The current review describes international research on OUD treatment and opioid overdose, most coauthored by former NIDA fellows. The findings from outside the United States have important implications for best practices domestically and in other countries that are experiencing increases in OUD prevalence and related overdose deaths.

Computers and the Internet provide researchers with new options in surveying. When using electronic surveys, several practical and methodological issues need to be considered such as whether the majority of the surveyed population has Internet access and whether an e-mail or a Web-based survey is most appropriate. Other important considerations relate to Internet security issues and, in international research, the possibility of language barriers. Despite these challenges, electronic surveys offer a promising alternative to conventional mail surveys.

International centres of excellence based on research reactors

A number of high flux research reactors were, or will be constructed. Each of these high flux facilities has the potential to be an important regional or International Centre of Excellence based on Research Reactors (ICERR) and scientific hub for research and materials investigations. Some are so organized currently, but for many there is a strongly national focus and scope for a significant expansion of their international role. There are manifold benefits of an expanded international role both for the ICERR's themselves and for the institutes that affiliate with them. These benefits include increased utilization and financial stability, increased international prestige, and enhanced scientific resources and capabilities. There are significant hurdles to obtaining the benefits from an expanded international role. For example, to achieve its full potential an ICERR must accommodate scientists from other nations, and include the plans and aspirations of the international community in the ICERR governance. The ICERR must also fully meet the national responsibilities for safety and security. Balancing these potentially conflicting requirements and finding a path through the organisational and legal issues is a significant challenge for any institute. The existing ICERR's therefore provide important case studies and examples of best practice that could inform the actions of other potential ICERR's. This paper describes an IAEA initiative to encourage and support the formation of new ICERR's, strengthen existing ones, and increase training resources available to Member States. The initiative will seek to share best practice and facilitate meetings and technical exchanges between the existing and potential ICERRs, and between the potential ICERR's and potential subscribing or affiliating institutes.

The worldwide nanotechnology research and development (R and D) investment reported by government organizations has increased by a factor of 3.5 between 1997 and 2001, and the highest rate of 90% is in 2001. At least 30 countries have initiated or are beginning national activities in this field. Scientists have opened a broad net of discoveries that does not leave any major research area untouched in physical, biological, and engineering sciences. Industry has gained confidence that nanotechnology will bring competitive advantages. The worldwide annual industrial production is estimated to exceed $1 trillion in 10-15 years from now, which would require about 2 million nanotechnology workers. U.S. has initiated a multidisciplinary strategy for development of science and engineering fundamentals through the National Nanotechnology Initiative. Japan and Europe have broad programs, and their current plans look ahead to four to five years. Other countries have encouraged their own areas of strength, several of them focusing on fields of the potential markets. Differences among countries are observed in the research domain they are aiming for, the level of program integration into various industrial sectors, and in the time scale of their R and D targets. Nanotechnology is growing in an environment where international interactions accelerate in science, education and industrial R and D. A global strategy of mutual interest is envisioned by connecting individual programs of contributing countries, professional communities, and international organizations

2011-01-01

In 2010, the International Space Station (ISS) construction and assembly was completed to become a world-class scientific research laboratory. We are now in the era of utilization of this unique platform that facilitates ground-breaking research in the microgravity environment. There are opportunities for NASA-funded research; research funded under the auspice of the United States National Laboratory; and research funded by the International Partners - Japan, Europe, Russia and Canada. The ISS facilities offer an opportunity to conduct research in a multitude of disciplines such as biology and biotechnology, physical science, human research, technology demonstration and development; and earth and space science. The ISS is also a unique resource for educational activities that serve to motivate and inspire students to pursue careers in Science, Technology, Engineering and Mathematics. Even though we have just commenced full utilization of the ISS as a science laboratory, early investigations are yielding major results that are leading to such things as vaccine development, improved cancer drug delivery methods and treatment for debilitating diseases, such as Duchenne's Muscular Dystrophy.

User-Friendly Predictive Modeling of Greenhouse Gas (GHG) Fluxes and Carbon Storage in Tidal Wetlands

Science.gov (United States)

Ishtiaq, K. S.; Abdul-Aziz, O. I.

2015-12-01

We developed user-friendly empirical models to predict instantaneous fluxes of CO2 and CH4 from coastal wetlands based on a small set of dominant hydro-climatic and environmental drivers (e.g., photosynthetically active radiation, soil temperature, water depth, and soil salinity). The dominant predictor variables were systematically identified by applying a robust data-analytics framework on a wide range of possible environmental variables driving wetland greenhouse gas (GHG) fluxes. The method comprised of a multi-layered data-analytics framework, including Pearson correlation analysis, explanatory principal component and factor analyses, and partial least squares regression modeling. The identified dominant predictors were finally utilized to develop power-law based non-linear regression models to predict CO2 and CH4 fluxes under different climatic, land use (nitrogen gradient), tidal hydrology and salinity conditions. Four different tidal wetlands of Waquoit Bay, MA were considered as the case study sites to identify the dominant drivers and evaluate model performance. The study sites were dominated by native Spartina Alterniflora and characterized by frequent flooding and high saline conditions. The model estimated the potential net ecosystem carbon balance (NECB) both in gC/m2 and metric tonC/hectare by up-scaling the instantaneous predicted fluxes to the growing season and accounting for the lateral C flux exchanges between the wetlands and estuary. The entire model was presented in a single Excel spreadsheet as a user-friendly ecological engineering tool. The model can aid the development of appropriate GHG offset protocols for setting monitoring plans for tidal wetland restoration and maintenance projects. The model can also be used to estimate wetland GHG fluxes and potential carbon storage under various IPCC climate change and sea level rise scenarios; facilitating an appropriate management of carbon stocks in tidal wetlands and their incorporation into a

Climate Change and International Civil Aviation Negotiations

Directory of Open Access Journals (Sweden)

Veronica Korber Gonçalves

Full Text Available Abstract The International Civil Aviation Organization (ICAO has discussed ways of regulating greenhouse gas (GHG emissions by civil aircraft for almost 20 years. Over the past four years, a consensus has developed about a market-based mechanism in the form of a carbon offset system. This article describes the route to the agreement reached by ICAO’s 39th Assembly, in order to contextualise the results and point out some of its limitations. It points to two main factors that contributed to the consensus: the role of the European Union, which sought to lead the negotiations, and the choice of a flexible and ultimately weak mechanism that received support from the international airlines.

2008-02-02

Target-setting agreements, also known as voluntary ornegotiated agreements, have been used by a number of governments as amechanism for promoting energy efficiency within the industrial sector. Arecent survey of such target-setting agreement programs identified 23energy efficiency or GHG emissions reduction voluntary agreement programsin 18 countries. International best practice related to target-settingagreement programs calls for establishment of a coordinated set ofpolicies that provide strong economic incentives as well as technical andfinancial support to participating industries. The key program elementsof a target-setting program are the target-setting process,identification of energy-saving technologies and measures usingenergy-energy efficiency guidebooks and benchmarking as well as byconducting energy-efficiency audits, development of an energy-savingsaction plan, development and implementation of energy managementprotocols, development of incentives and supporting policies, monitoringprogress toward targets, and program evaluation. This report firstprovides a description of three key target-setting agreement programs andthen describes international experience with the key program elementsthat comprise such programs using information from the three keytarget-setting programs as well as from other international programsrelated to industrial energy efficiency or GHG emissionsreductions.

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

Science.gov (United States)

Timilsina, Govinda R; Shrestha, Ram M

2006-09-01

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

Life cycle GHG emissions from Malaysian oil palm bioenergy development: The impact on transportation sector's energy security

International Nuclear Information System (INIS)

Hassan, Mohd Nor Azman; Jaramillo, Paulina; Griffin, W. Michael

2011-01-01

Malaysia's transportation sector accounts for 41% of the country's total energy use. The country is expected to become a net oil importer by the year 2011. To encourage renewable energy development and relieve the country's emerging oil dependence, in 2006 the government mandated blending 5% palm-oil biodiesel in petroleum diesel. Malaysia produced 16 million tonnes of palm oil in 2007, mainly for food use. This paper addresses maximizing bioenergy use from oil-palm to support Malaysia's energy initiative while minimizing greenhouse-gas emissions from land-use change. When converting primary and secondary forests to oil-palm plantations between 270-530 and 120-190 g CO 2 -equivalent per MJ of biodiesel produced, respectively, is released. However, converting degraded lands results in the capture of between 23 and 85 g CO 2 -equivalent per MJ of biodiesel produced. Using various combinations of land types, Malaysia could meet the 5% biodiesel target with a net GHG savings of about 1.03 million tonnes (4.9% of the transportation sector's diesel emissions) when accounting for the emissions savings from the diesel fuel displaced. These findings are used to recommend policies for mitigating GHG emissions impacts from the growth of palm oil use in the transportation sector. - Research highlights: → We modeled greenhouse gas emissions in the production of palm-biodiesel. → Five land types were included to model emissions associated with land-use change. → Land-use change has the biggest impact on the emissions in making palm-biodiesel. → Emissions from fertilizer use and effluent treatment are still significant. → At 5% biodiesel grown on suitable lands Malaysia would obtain an emissions savings.

Full Text Available Abstract Background In the United States, the Accreditation Council of graduate medical education (ACGME requires all accredited Internal medicine residency training programs to facilitate resident scholarly activities. However, clinical experience and medical education still remain the main focus of graduate medical education in many Internal Medicine (IM residency-training programs. Left to design the structure, process and outcome evaluation of the ACGME research requirement, residency-training programs are faced with numerous barriers. Many residency programs report having been cited by the ACGME residency review committee in IM for lack of scholarly activity by residents. Methods We would like to share our experience at Lincoln Hospital, an affiliate of Weill Medical College Cornell University New York, in designing and implementing a successful structured research curriculum based on ACGME competencies taught during a dedicated "research rotation". Results Since the inception of the research rotation in 2004, participation of our residents among scholarly activities has substantially increased. Our residents increasingly believe and appreciate that research is an integral component of residency training and essential for practice of medicine. Conclusion Internal medicine residents' outlook in research can be significantly improved using a research curriculum offered through a structured and dedicated research rotation. This is exemplified by the improvement noted in resident satisfaction, their participation in scholarly activities and resident research outcomes since the inception of the research rotation in our internal medicine training program.

Towards the development of a GHG emissions baseline for the Agriculture, Forestry and Other Land Use (AFOLU sector, South Africa

Directory of Open Access Journals (Sweden)

Luanne B. Stevens

2016-12-01

Full Text Available South Africa is a signatory to the United Nations Framework Convention on Climate Change (UNFCCC and as such is required to report on Greenhouse gas (GHG emissions from the Energy, Transport, Waste and the Agriculture, Forestry and Other Land Use (AFOLU sectors every two years in national inventories. The AFOLU sector is unique in that it comprises both sources and sinks for GHGs. Emissions from the AFOLU sector are estimated to contribute a quarter of the total global greenhouse gas emissions. GHG emissions sources from agriculture include enteric fermentation; manure management; manure deposits on pastures, and soil fertilization. Emissions sources from Forestry and Other Land Use (FOLU include anthropogenic land use activities such as: management of croplands, forests and grasslands and changes in land use cover (the conversion of one land use to another. South Africa has improved the quantification of AFOLU emissions and the understanding of the dynamic relationship between sinks and sources over the past decade through projects such as the 2010 GHG Inventory, the Mitigation Potential Analysis (MPA, and the National Terrestrial Carbon Sinks Assessment (NTCSA. These projects highlight key mitigation opportunities in South Africa and discuss their potentials. The problem remains that South Africa does not have an emissions baseline for the AFOLU sector against which the mitigation potentials can be measured. The AFOLU sector as a result is often excluded from future emission projections, giving an incomplete picture of South Africa’s mitigation potential. The purpose of this project was to develop a robust GHG emissions baseline for the AFOLU sector which will enable South Africa to project emissions into the future and demonstrate its contribution towards the global goal of reducing emissions.

Geocognition Research: An International Discipline (Invited)

Science.gov (United States)

Libarkin, J.

2009-12-01

Geocognition and geoscience education research have experienced a dramatic increase in research productivity and graduate student training in the past decade. At this writing, over twelve U.S. graduate programs dedicated to geocognition and geoscience education research exist within geoscience departments, with numerous other programs housed within education. International research programs are experiencing similar increases in these research domains. This insurgence of graduate training opportunities is due in large part to several factors, including: An increased awareness of the importance of Earth Systems Science to public understanding of science, particularly in light of global concern about climate change; new funding opportunities for science education, cognitive science, and geoscience education research; and, engagement of a significant part of the geosciences and education communities in writing new standards for Earth Systems literacy. Existing research programs blend geoscience content knowledge with research expertise in education, cognitive science, psychology, sociology and related disciplines. Research projects reflect the diversity of interests in geoscience teaching and learning, from investigations of pedagogical impact and professional development to studies of fundamental geocognitive processes.

An investigation of the techno-economic impact of internal combustion engine based cogeneration systems on the energy requirements and greenhouse gas emissions of the Canadian housing stock

Asaee, S. Rasoul; Ugursal, V. Ismet; Beausoleil-Morrison, Ian

2015-01-01

This study provides a techno-economic evaluation of retrofitting internal combustion engine (ICE) based cogeneration systems in the Canadian housing stock (CHS). The study was conducted using the Canadian Hybrid Residential End-Use Energy and GHG Emissions Model (CHREM). CHREM includes close to 17,000 unique house files that are statistically representative of the Canadian housing stock. The cogeneration system performance was evaluated using a high resolution integrated building performance simulation software. It is assumed that the ICE cogeneration system is retrofitted into all houses that currently use a central space heating system and have a suitable basement or crawl space. The GHG emission intensity factor associated with marginal electricity generation in each province is used to estimate the annual GHG emissions reduction due to the cogeneration system retrofit. The results show that cogeneration retrofit yields 13% energy savings in the CHS. While the annual GHG emissions would increase in some provinces due to cogeneration retrofits, the total GHG emissions of the CHS would be reduced by 35%. The economic analysis indicates that ICE cogeneration system retrofits may provide an economically feasible opportunity to approach net/nearly zero energy status for existing Canadian houses. - Highlights: • Techno-economic evaluation ICE cogeneration systems for Canadian housing is reported. • ICE cogeneration retrofit could yield 13% annual energy savings in Canadian housing. • Annual GHG emissions of Canadian housing could decrease by 35% with ICE cogeneration. • But, in some provinces, GHG emissions would increase as a result of ICE cogeneration

The International Permafrost Association (IPA), founded in 1983, has as its objectives to foster the dissemination of knowledge concerning permafrost and to promote cooperation among persons and national or international organizations engaged in scientific investigation and engineering work on permafrost. The IPA's primary responsibilities are convening International Permafrost Conferences, undertaking special projects such as preparing databases, maps, bibliographies, and glossaries, and coordinating international field programs and networks. Membership is through adhering national or multinational organizations or as individuals in countries where no Adhering Body exists. The IPA is governed by its Executive Committee and a Council consisting of representatives from 26 Adhering Bodies having interests in some aspect of theoretical, basic and applied frozen ground research, including permafrost, seasonal frost, artificial freezing and periglacial phenomena. This presentation details the IPA core products, achievements and activities as well as current projects in cryospheric research. One of the most important core products is the circumpolar permafrost map. The IPA also fosters and supports the activities of the Global Terrestrial Network on Permafrost (GTN-P) sponsored by the Global Terrestrial Observing System, GTOS, and the Global Climate Observing System, GCOS, whose long-term goal is to obtain a comprehensive view of the spatial structure, trends, and variability of changes in the active layer thickness and permafrost temperature. A further important initiative of the IPA are the biannually competitively-funded Action Groups which work towards the production of well-defined products over a period of two years. Current IPA Action Groups are working on highly topical and interdisciplinary issues, such as the development of a regional Palaeo-map of Permafrost in Eurasia, the integration of multidisciplinary knowledge about the use of thermokarst and permafrost

A Mechanistically Informed User-Friendly Model to Predict Greenhouse Gas (GHG) Fluxes and Carbon Storage from Coastal Wetlands

Science.gov (United States)

Abdul-Aziz, O. I.; Ishtiaq, K. S.

2015-12-01

We present a user-friendly modeling tool on MS Excel to predict the greenhouse gas (GHG) fluxes and estimate potential carbon sequestration from the coastal wetlands. The dominant controls of wetland GHG fluxes and their relative mechanistic linkages with various hydro-climatic, sea level, biogeochemical and ecological drivers were first determined by employing a systematic data-analytics method, including Pearson correlation matrix, principal component and factor analyses, and exploratory partial least squares regressions. The mechanistic knowledge and understanding was then utilized to develop parsimonious non-linear (power-law) models to predict wetland carbon dioxide (CO2) and methane (CH4) fluxes based on a sub-set of climatic, hydrologic and environmental drivers such as the photosynthetically active radiation, soil temperature, water depth, and soil salinity. The models were tested with field data for multiple sites and seasons (2012-13) collected from the Waquoit Bay, MA. The model estimated the annual wetland carbon storage by up-scaling the instantaneous predicted fluxes to an extended growing season (e.g., May-October) and by accounting for the net annual lateral carbon fluxes between the wetlands and estuary. The Excel Spreadsheet model is a simple ecological engineering tool for coastal carbon management and their incorporation into a potential carbon market under a changing climate, sea level and environment. Specifically, the model can help to determine appropriate GHG offset protocols and monitoring plans for projects that focus on tidal wetland restoration and maintenance.

Review of research in internal-wave and internal-tide deposits of China: Discussion

Directory of Open Access Journals (Sweden)

G. Shanmugam

2014-10-01

Full Text Available This discussion of a review article by [27], published in the Journal of Palaeogeography (2(1: 56– 65, is aimed at illustrating that interpretations of ten ancient examples in China and one in the central Appalachians (USA as deep-water deposits of internal waves and internal tides are unsustainable. This critical assessment is based on an in-depth evaluation of oceanographic and sedimentologic data on internal waves and internal tides derived from 332 print and online published works during 1838–January 2013, which include empirical data on the physical characteristics of modern internal waves and internal tides from 51 regions of the world’s oceans [108]. In addition, core and outcrop descriptions of deep-water strata from 35 case studies worldwide carried out by the author during 1974–2011, and a selected number of case studies published by other researchers are evaluated for identifying the sedimentological challenges associated with distinguishing types of bottom-current reworked sands in the ancient sedimentary record. The emerging conclusion is that any interpretation of ancient strata as deposits of internal waves and internal tides is premature.

Empirical research on international environmental migration: a systematic review.

Science.gov (United States)

Obokata, Reiko; Veronis, Luisa; McLeman, Robert

2014-01-01

This paper presents the findings of a systematic review of scholarly publications that report empirical findings from studies of environmentally-related international migration. There exists a small, but growing accumulation of empirical studies that consider environmentally-linked migration that spans international borders. These studies provide useful evidence for scholars and policymakers in understanding how environmental factors interact with political, economic and social factors to influence migration behavior and outcomes that are specific to international movements of people, in highlighting promising future research directions, and in raising important considerations for international policymaking. Our review identifies countries of migrant origin and destination that have so far been the subject of empirical research, the environmental factors believed to have influenced these migrations, the interactions of environmental and non-environmental factors as well as the role of context in influencing migration behavior, and the types of methods used by researchers. In reporting our findings, we identify the strengths and challenges associated with the main empirical approaches, highlight significant gaps and future opportunities for empirical work, and contribute to advancing understanding of environmental influences on international migration more generally. Specifically, we propose an exploratory framework to take into account the role of context in shaping environmental migration across borders, including the dynamic and complex interactions between environmental and non-environmental factors at a range of scales.

Modeling Water Resource Systems Accounting for Water-Related Energy Use, GHG Emissions and Water-Dependent Energy Generation in California

Science.gov (United States)

Escriva-Bou, A.; Lund, J. R.; Pulido-Velazquez, M.; Medellin-Azuara, J.

2015-12-01

Most individual processes relating water and energy interdependence have been assessed in many different ways over the last decade. It is time to step up and include the results of these studies in management by proportionating a tool for integrating these processes in decision-making to effectively understand the tradeoffs between water and energy from management options and scenarios. A simple but powerful decision support system (DSS) for water management is described that includes water-related energy use and GHG emissions not solely from the water operations, but also from final water end uses, including demands from cities, agriculture, environment and the energy sector. Because one of the main drivers of energy use and GHG emissions is water pumping from aquifers, the DSS combines a surface water management model with a simple groundwater model, accounting for their interrelationships. The model also explicitly includes economic data to optimize water use across sectors during shortages and calculate return flows from different uses. Capabilities of the DSS are demonstrated on a case study over California's intertied water system. Results show that urban end uses account for most GHG emissions of the entire water cycle, but large water conveyance produces significant peaks over the summer season. Also the development of more efficient water application on the agricultural sector has increased the total energy consumption and the net water use in the basins.

Availability of Biomass Residues for Co-Firing in Peninsular Malaysia: Implications for Cost and GHG Emissions in the Electricity Sector

Directory of Open Access Journals (Sweden)

W. Michael Griffin

2014-02-01

Full Text Available Fossil fuels comprise 93% of Malaysia’s electricity generation and account for 36% of the country’s 2010 Greenhouse Gas (GHG emissions. The government has targeted the installation of 330 MW of biomass electricity generation capacity by 2015 to avoid 1.3 Mt of CO2 emissions annually and offset some emissions due to increased coal use. One biomass option is to co-fire with coal, which can result in reduced GHG emissions, coal use, and costs of electricity. A linear optimization cost model was developed using seven types of biomass residues for Peninsular Malaysia. Results suggest that about 12 Mt/year of residues are available annually, of which oil-palm residues contribute 77%, and rice and logging residues comprise 17%. While minimizing the cost of biomass and biomass residue transport, co-firing at four existing coal plants in Peninsular Malaysia could meet the 330 MW biomass electricity target and reduce costs by about $24 million per year compared to coal use alone and reduces GHG emissions by 1.9 Mt of CO2. Maximizing emissions reduction for biomass co-firing results in 17 Mt of CO2 reductions at a cost of $23/t of CO2 reduced.

The rapid growth of vehicles has resulted in continuing growth in China's oil demand. This paper analyzes future trends of both direct and life cycle energy demand (ED) and greenhouse gas (GHG) emissions in China's road transport sector, and assesses the effectiveness of possible reduction measures by using alternative vehicles/fuels. A model is developed to derive a historical trend and to project future trends. The government is assumed to do nothing additional in the future to influence the long-term trends in the business as usual (BAU) scenario. Four specific scenarios are used to describe the future cases where different alternative fuel/vehicles are applied. The best case scenario is set to represent the most optimized case. Direct ED and GHG emissions would reach 734 million tonnes of oil equivalent and 2384 million tonnes carbon dioxide equivalent by 2050 in the BAU case, respectively, more than 5.6 times of 2007 levels. Compared with the BAU case, the relative reductions achieved in the best case would be 15.8% and 27.6% for life cycle ED and GHG emissions, respectively. It is suggested for future policy implementation to support sustainable biofuel and high efficient electric-vehicles, and the deployment of coal-based fuels accompanied with low-carbon technology.

The rapid growth of vehicles has resulted in continuing growth in China's oil demand. This paper analyzes future trends of both direct and life cycle energy demand (ED) and greenhouse gas (GHG) emissions in China's road transport sector, and assesses the effectiveness of possible reduction measures by using alternative vehicles/fuels. A model is developed to derive a historical trend and to project future trends. The government is assumed to do nothing additional in the future to influence the long-term trends in the business as usual (BAU) scenario. Four specific scenarios are used to describe the future cases where different alternative fuel/vehicles are applied. The best case scenario is set to represent the most optimized case. Direct ED and GHG emissions would reach 734 million tonnes of oil equivalent and 2384 million tonnes carbon dioxide equivalent by 2050 in the BAU case, respectively, more than 5.6 times of 2007 levels. Compared with the BAU case, the relative reductions achieved in the best case would be 15.8% and 27.6% for life cycle ED and GHG emissions, respectively. It is suggested for future policy implementation to support sustainable biofuel and high efficient electric-vehicles, and the deployment of coal-based fuels accompanied with low-carbon technology.

This directory includes approximately 31,000 organizations that reported energy-related literature from 1988 to 1992 and updates the DOE Energy Data Base: Corporate Author Entries.

RESEARCH ON THE INTERNATIONAL ACCOUNTING HARMONIZATION PROCESS

Directory of Open Access Journals (Sweden)

Tatiana Danescu

2016-12-01

Full Text Available During the last decades, the need of harmonization of the financial reporting frameworks has become more acute, mostly because the capital markets are not restricted anymore by country borders and capital movement has outlined the phenomenon of globalization and internationalism. A significant step in harmonizing the financial reporting was done in the process of normalization through different sets of rules and principles, recognized and applied in many states are the International Financial Reporting Standards (IFRS. The process of international recognition of these standards continues along with conceptual development which is based on epistemological research on specific markets, industries, economies open to international capital flows. In this context it becomes of interest to identify and understand generally accepted and applied accounting elements which carry forward the accounting harmonization process along with factors and circumstances that create diversity in nationally applied financial reporting frameworks.

Tax and Fiscal Policies for Promotion of Industrial EnergyEfficiency: A Survey of International Experience

Energy Technology Data Exchange (ETDEWEB)

Price, Lynn; Galitsky, Christina; Sinton, Jonathan; Worrell,Ernst; Graus, Wina

2005-09-15

The Energy Foundation's China Sustainable Energy Program (CSEP) has undertaken a major project investigating fiscal and tax policy options for stimulating energy efficiency and renewable energy development in China. This report, which is part of the sectoral sub-project studies on energy efficiency in industry, surveys international experience with tax and fiscal policies directed toward increasing investments in energy efficiency in the industrial sector. The report begins with an overview of tax and fiscal policies, including descriptions and evaluations of programs that use energy or energy-related carbon dioxide (CO2) taxes, pollution levies, public benefit charges, grants or subsidies, subsidized audits, loans, tax relief for specific technologies, and tax relief as part of an energy or greenhouse gas (GHG) emission tax or agreement scheme. Following the discussion of these individual policies, the report reviews experience with integrated programs found in two countries as well as with GHG emissions trading programs. The report concludes with a discussion of the best practices related to international experience with tax and fiscal policies to encourage investment in energy efficiency in industry.

Taking stock of the ethical foundations of international health research: pragmatic lessons from the IU-Moi Academic Research Ethics Partnership.

Science.gov (United States)

Meslin, Eric M; Were, Edwin; Ayuku, David

2013-09-01

It is a sine qua non that research and health care provided in international settings raise profound ethical questions when different cultural and political values are implicated. Yet ironically, as international health research expands and as research on ethical issues in international health research broadens and deepens, we appear to have moved away from discussing the moral foundations of these activities. For international health research to thrive and lead to the kind of benefits it is capable of, it is helpful to occasionally revisit the foundational premises that justify the enterprise as a whole. We draw on the experience of the Indiana University-Moi University Academic Research Ethics Partnership, an innovative bioethics training program co-located in Indianapolis and Eldoret, Kenya to highlight the changing nature of ethical issues in international health research and the ongoing practical challenges.

Research on the International Space Station - An Overview

Science.gov (United States)

Evans, Cynthia A.; Robinson, Julie A.; Tate-Brown, Judy M.

2009-01-01

The International Space Station (ISS) celebrates ten years of operations in 2008. While the station did not support permanent human crews during the first two years of operations November 1998 to November 2000 it hosted a few early science experiments months before the first international crew took up residence. Since that time and simultaneous with the complicated task of ISS construction and overcoming impacts from the tragic Columbia accident science returns from the ISS have been growing at a steady pace. As of this writing, over 162 experiments have been operated on the ISS, supporting research for hundreds of ground-based investigators from the U.S. and international partners. This report summarizes the experimental results collected to date. Today, NASA's priorities for research aboard the ISS center on understanding human health during long-duration missions, researching effective countermeasures for long-duration crewmembers, and researching and testing new technologies that can be used for future exploration crews and spacecraft. Through the U.S. National Laboratory designation, the ISS is also a platform available to other government agencies. Research on ISS supports new understandings, methods or applications relevant to life on Earth, such as understanding effective protocols to protect against loss of bone density or better methods for producing stronger metal alloys. Experiment results have already been used in applications as diverse as the manufacture of solar cell and insulation materials for new spacecraft and the verification of complex numerical models for behavior of fluids in fuel tanks. A synoptic publication of these results will be forthcoming in 2009. At the 10-year point, the scientific returns from ISS should increase at a rapid pace. During the 2008 calendar year, the laboratory space and research facilities were tripled with the addition of ESA's Columbus and JAXA's Kibo scientific modules joining NASA's Destiny Laboratory.

The reduction of greenhouse gases (GHG) emissions in the supply chain for biofuels is a big challenge especially for the German and European cultivation of energy crops. The production of nitrogen fertilizers and field emissions are the main factors of GHG emissions. The amount of field emissions depends very strongly on the nitrogen effort and the intensity of tillage. The main objective is to reduce GHG emissions in field cropping systems within the biofuel production chains. An inclusion of legumes into crop rotations is particularly important because their cultivation does not require nitrogen fertilizer. Data base for the project is a complex field experiment with the biofuel crops winter rape and winter wheat. Previous crops are winter wheat, peas and lupins. ln each case tilling systems are compared with non-tilling. The first results of the field experiments are nitrogen functions depending on previous crops, sites and tilling system. Calculation models for GHG reduction models were developed on the bases of these results. By growing legumes as previous crops before wheat and rape it is possible to reduce GHG emissions from 2 to 10 g CO{sub 2eq} per MJ. The best reduction of GHG emissions is possible by combining legumes as previous crops with a reduced nitrogen effort.

IS THE INTERNATIONAL BUSINESS ENVIRONMENT THE ACTUAL CONTEXT FOR INTERNATIONAL BUSINESS RESEARCH?

Directory of Open Access Journals (Sweden)

Fernando A. Ribeiro Serra

2009-07-01

Full Text Available The International Business Environment (IBE has been argued to be the essential context for international business (IB studies and the distinguishing factor from other management studies and studies of large enterprises. Two content analysis show that many papers published in top tier IB journals either lack reference to any dimension of the IBE or tend to be uni-or bi-dimensional when addressing the IBE; it is not a surprise that the cultural dimension is the most often used. We suggest that: (a there is need to developed more uni-and multi-dimensional environmental constructs; (ba more holistic view of the IBE provides richer insights on the actual complexity underlying IB research. Future studiesthat provide more comprehensive models of the IBE that overcome the usual broad classifications of the internationalenvironment as undefined and uncontrollable factors are warranted to advance conceptual and empirical research.

Panorama 2010: CO2 markets and the current status of international climate negotiations

The emission of greenhouse gases (GHGs) to the atmosphere is causing climatic disturbances of increasing severity, representing risks for the entire planet. Existing GHG emissions reduction policies mainly focus on setting up cap and trade systems (carbon markets) geared to achieving such reductions. The Kyoto Protocol, an international treaty established under the auspices of the United Nations, sets forth the guiding principles, objectives and legally binding targets imposed on the parties concerned until 2012. The purpose of the international negotiations underway is to set up a new regulatory framework for the post-2012 period. (author)

Accounting for time-dependent changes in GHG emissions in the Ribeiro appellation (NW Spain): Are land use changes an important driver?

International Nuclear Information System (INIS)

Villanueva-Rey, Pedro; Vázquez-Rowe, Ian; Otero, Marta; Moreira, María Teresa; Feijoo, Gumersindo

2015-01-01

Highlights: • The environmental profile of a wine appellation was assessed for a 20 year period. • LUCs and LCA methods were linked to assess the GHG emissions in the appellation. • Winegrowing operations and land use were monitored up to the gate of the winery. • Different trends were found depending on the period assessed. • Demographic and social changes triggered changes in the carbon stocks. - Abstract: Land use changes (LUCs) constitute a crucial source of environmental impact in production systems, which are mostly associated with greenhouse gas (GHG) emissions. This circumstance is especially important for the agricultural sector, since these imply an important proportion of the total GHG emissions occurring worldwide. Wine and grape production is a key sector in Spain, representing the largest surface area at European level. In the past decades, important wine related LUCs have been observed due to changes in farming methods/type, number of Denominations of Origin, and the establishment of larger wineries that have enhanced exports. The current study presents a temporally based Life Cycle Assessment (LCA) study of the Ribeiro appellation in NW Spain, in which the gradual changes in the land use, as well as the technological improvements are analyzed in detail in order to understand how the environmental profile of this specific wine producing area has shifted in the past two decades (i.e., from 1990 to 2009). On the one hand, phenomena such as afforestation and agricultural intensification are analyzed throughout the appellation to estimate the impact due to GHG emissions linked to LUCs, based on IPCC standards. On the other hand, trends linked to technological improvements, operational changes, such as changes in the use and management of plant protection agents or fertilizers or the change in the energy sources for machinery on the vineyards, were assessed in detail

Marine energy consumption, national economic activity, and greenhouse gas emissions from international shipping

International Nuclear Information System (INIS)

Chang, Ching-Chih

2012-01-01

The causal relationships among marine energy consumption, greenhouse gas emissions from international shipping, and economic growth for Kyoto Protocol Annex I countries for the period of 1990 to 2006 are discussed. The real gross domestic product is used as a proxy for economic activity. The United States is also discussed because it was the main global polluter before 2006. The co-integration methodology and an error-correction model are used to examine the causal relationships. The empirical results show that marine energy consumption and GDP are the main factors of increased GHG emissions in the short-run, and that economic activity significantly increased emissions in the long-run. Emissions from shipping are more closely related to marine energy consumption than to economic activity. Hence, policies for mitigating greenhouse gas emissions from marine shipping need to focus on greater energy efficiency in the design of ship engines and hulls. - Highlights: ► Energy consumption and GDP are the main causes to increased GHG emissions in the shipping industry. ► Emissions from shipping are more closely related to energy consumption than to GDP. ► Policies to mitigate GHG emissions from shipping industry should focus on the engine and hull design.

Accelerating the development and diffusion of new energy technologies: Beyond the 'valley of death'

International Nuclear Information System (INIS)

Weyant, John P.

2011-01-01

There are at least three motivations for government intervention in GHG mitigation: (1) inducing the private sector to reduce GHG emissions directly by setting a price on emissions, (2) increasing the amount of innovative activity in GHG mitigation technology development, and (3) educating the public regarding GHG-reducing investment opportunities, allowing consumers to make better private decisions. This paper discusses the pros and cons of policy instruments that might be used to respond to these motivations and makes recommendations for an appropriate mix of policy instruments over time given both economic and policital/instituional considerations. - Research Highlights: → Increases in pre-competitive energy R and D and energy efficiency technology diffusion policies in the US are highly desirable. → The cost of well designed programs in these areas can be low and the pay off very high. → Such policies make sense even if the GHG externality is internalized through a GHG tax or equivalent, but are even more desirable if they are not.

Future energy loads for a large-scale adoption of electric vehicles in the city of Los Angeles: Impacts on greenhouse gas (GHG) emissions

International Nuclear Information System (INIS)

Kim, Jae D.; Rahimi, Mansour

2014-01-01

Using plug-in electric vehicles (PEVs) has become an important component of greenhouse gas (GHG) emissions reduction strategy in the transportation sector. Assessing the net effect of PEVs on GHG emissions, however, is dependent on factors such as type and scale of electricity generation sources, adoption rate, and charging behavior. This study creates a comprehensive model that estimates the energy load and GHG emissions impacts for the years 2020 and 2030 for the city of Los Angeles. For 2020, model simulations show that the PEV charging loads will be modest with negligible effects on the overall system load profile. Contrary to previous study results, the average marginal carbon intensity is higher if PEV charging occurs during off-peak hours. These results suggest that current economic incentives to encourage off-peak charging result in greater GHG emissions. Model simulations for 2030 show that PEV charging loads increase significantly resulting in potential generation shortages. There are also significant grid operation challenges as the region's energy grid is required to ramp up and down rapidly to meet PEV loads. For 2030, the average marginal carbon intensity for off-peak charging becomes lower than peak charging mainly due to the removal of coal from the power generation portfolio. - Highlights: • Future energy load from PEV charging in the city of Los Angeles is modeled. • Changes in the marginal carbon intensity of the region's electric grid are modeled. • In the short run, offpeak charging results in higher marginal carbon intensity. • There is a mismatch between emissions and economic incentives for charging

Gutlein, A.; Ralf, K.; Gerschlauer, F.; Dannenmann, M.; Butterbach-Bahl, K.; Diaz-Pines, E.

2016-12-01

In a rapidly changing world understanding of natural ecosystems response to human perturbations such as land use and climate changes as well as habitat destruction is crucial with respect to sustainability of ecosystem services. This is particularily true for tropical forest ecosystems which have significant effects on the major biogeochemical cycles and global climate. Here we present a comprehensive dataset of nitrogen cycling and GHG emissions of natural and managed ecosystems along land use and climate gradients at Mt. Kilimanjaro, Tanzania including different forest ecosystems, homegardens, and coffee plantations. Soil N turnover rates were highest in the Ocotea forest and progressively decreased with decreasing annual rainfall and increasing land use intensity. Nitrogen production and immobilization rates positively correlated with soil organic C and total N concentrations as well as substrate availability of dissolved organic C and N, but correlated less with soil ammonium and nitrate concentrations. By using indicators of N retention and characteristics of soil nutrient status, we observed a grouping of faster, but tighter N cycling in the (semi-) natural savanna, Helychrysum and Ocotea forest. This contrasted with a more open N cycle in managed systems (homegarden and coffee plantation) where N was more prone to leaching or gaseous losses due to high nitrate production rates. The partly disturbed lower montane forest ranged in between these two groups. These finding could be supported by differences in natural 15N abundance of litter and soil across all sites. Comparing GHG emissions at the land use gradient showed, that with increasing intensification (lower montane forest - homegarden - coffee plantation) N2O emissions increased but at the same time the soil sink for atmospheric CH4 decreased. GHG emission measurements at the climate gradient (savanna, lower montane, Ocotea and Podocarpus forest, Helychrysum) revealed that differences in soil moisture

Ethics of international clinical research collaboration - the experience of AlloStem.

Science.gov (United States)

Chaplin, C

2006-02-01

This paper examines the ethics of international clinical collaboration in stem cell research by focusing on the AlloStem project. AlloStem is an international research programme, financed by the European Union under the Sixth Framework Programme, with the aim of advancing the use of stem cells in treating leukaemia and other haematological diseases. Several areas of ethical importance are explored. Research justification and the need to consider both deontological and teleological aspects are examined. Ethical sensitivity in research and the requirement to respond to areas of ethical concern identified by the European Commission, such as the involvement of human beings, the use of human tissue, and the use of animals are also explored. Ethical issues around project structure and management, such as ethical standardization in international research, and achieving set targets are discussed. The ethical importance of dissemination of findings and teaching in clinical research is also considered. Finally, the distribution of benefits is addressed and the importance of distributive justice is emphasized.

[Surgical research in Germany--an international comparison].

Science.gov (United States)

Fendrich, V; Rothmund, M

2010-04-01

Surgical research in Germany occupies a lower position in international ranking than expected. According to the size of the population, the economic impact, the gross domestic product and the research funding capacity, the impact of German surgical research should be much higher. Reasons are a more intensive commitment to patient care, structural differences and a changing lifestyle in younger doctors in comparison to many leading countries. If the situation is to be improved all factors have to be evaluated and, if possible, changed. Overall, German surgeons are underrepresented as readers and authors in the scientific market, which is mostly in the English language.

Cooperation of international Research Infrastructures to address environmental global challenges

Science.gov (United States)

Bonet García, Francisco J.; Suárez-Muñoz, María; Conchubhair, Diarmuid O.; Dohna, Tina; Lo Bue, Nadia

2017-04-01

Human impact on the planet is causing a set of global environmental problems that threaten the wellbeing of current and future generations. Examples of these environmental problems include climate change, decline of biodiversity, alteration of biogeochemical cycles, ocean acidification, etc. These environmental Global Challenges (GCs) are transnational and complex, combining elements of both natural and social factors. Providing solutions for these challenges can be significantly enhanced through the collaboration of various related institutions, governments and stakeholders. A deeper understanding of the causes and consequences of GCs, as well as the processes which control them is required. Environmental Research Infrastructures (DANUBIUS-RI) are key players in this learning process. Covering many fields of research, it is through RIs collaboration that GCs can be more fully addressed. However, the collaboration among environmental RIs is still limited nationally as well as internationally. Although contact is encouraged and interactions are common practice, there are few cases where RI managers initiate and foster transnational collaborations in order to address specific problems. The COOP+ project aims to explore and strengthen cooperation among global RIs by bringing various RIs together and working on the identification of requirements, strengths, knowledge gaps and other relevant items in regard to the selected GCs. For this purpose, 13 GCs have been selected: coral bleaching, marine debris, noise impact on marine fauna, Arctic sea ice melting, pollinators decline, threatened species, agriculture pollutants, nitrogen cycle, carbon and GHG, geohazards and extreme events, estuaries, global urbanization process, and ozone depletion. These GCs are being analysed and described by multidisciplinary teams of experts composed of scientists, RIs operators and other stakeholders. This assessment will derive a list of tasks and requirements to be fulfilled by the

Capturing and Processing Soil GHG Fluxes Using the LI-COR LI-8100A

Science.gov (United States)

Xu, Liukang; McDermitt, Dayle; Hupp, Jason; Johnson, Mark; Madsen, Rod

2015-04-01

The LI-COR LI-8100A Automated Soil CO2 Flux System is designed to measure soil CO2 efflux using automated chambers and a non-steady state measurement protocol. While CO2 is an important gas in many contexts, it is not the only gas of interest for many research applications. With some simple plumbing modifications, many third party analyzers capable of measuring other trace gases, e.g. N2O, CH4, or 13CO2 etc., can be interfaced with the LI-8100A System, and LI-COR's data processing software (SoilFluxPro™) can be used to compute fluxes for these additional gases. In this paper we describe considerations for selecting an appropriate third party analyzer to interface with the system, how to integrate data into the system, and the procedure used to compute fluxes of additional gases in SoilFluxPro™. A case study is presented to demonstrate methane flux measurements using an Ultra-Portable Greenhouse Gas Analyzer (Ultra-Portable GGA, model 915-0011), manufactured by Los Gatos Research and integrated into the LI-8100A System. Laboratory and field test results show that the soil CO2 efflux based on the time series of CO2 data measured either with the LI-8100A System or with the Ultra-Portable GGA are essentially the same. This suggests that soil GHG fluxes measured with both systems are reliable.

The extent of international research on the Research Consortium's program between 1965 and 2008 was documented. A total of 9,132 abstracts were reviewed, and 657 (7.19%) had an international component. Inclusion of international research ranged from a low of 1.97% in 1983 to a high of 14.24% in 2007. There was a decrease in the amount of international research presented between 1965 and 1983, after which there was an increase through 2008. Most growth was from increased contributions coming from researchers in Southeast Asia. In terms of general research topics, eight areas increased over the 44-year history reviewed, and five areas decreased. Seven recommendations are advanced for expanding the place and role of international research within the Research Consortium.
