Using the GAINS (Greenhouse Gas–Air Pollution Interactions and Synergies) model, we derived Annex I marginal abatement cost curves for the years 2020 and 2030 for three World Energy Outlook baseline scenarios (2007–2009) of the International Energy Agency. These cost curves are presented by country, by greenhouse gas and by sector. They are available for further inter-country comparisons in the GAINS Mitigation Efforts Calculator—a free online tool. We illustrate the influence of the baseline scenario on the shape of mitigation cost curves, and identify key low cost options as well as no-regret priority investment areas for the years 2010–2030. Finally, we show the co-effect of GHG mitigation on the emissions of local air pollutants and argue that these co-benefits offer strong local incentives for mitigation. 相似文献

The Clean Development Mechanism (CDM) of the Kyoto Protocol provides Annex-I (industrialized) countries with an incentive to invest in emission reduction projects in non-Annex-I (developing) countries to achieve a reduction in CO2 emissions at lowest cost that also promotes sustainable development in the host country. Biomass gasification projects could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development. However, there is only one biomass gasifier project registered under the CDM so far. In this study, an attempt has been made to assess the economic potential of biomass gasifier-based projects under CDM in India. The preliminary estimates based on this study indicate that there is a vast theoretical potential of CO2 mitigation by the use of biomass gasification projects in India.The results indicate that in India around 74 million tonne agricultural residues as a biomass feedstock can be used for energy applications on an annual basis. In terms of the plant capacity the potential of biomass gasification projects could reach 31 GW that can generate more than 67 TWh electricity annually. The annual CER potential of biomass gasification projects in India could theoretically reach 58 million tonnes. Under more realistic assumptions about diffusion of biomass gasification projects based on past experiences with the government-run programmes, annual CER volumes by 2012 could reach 0.4–1.0 million and 1.0–3.0 million by 2020. The projections based on the past diffusion trend indicate that in India, even with highly favorable assumptions, the dissemination of biomass gasification projects is not likely to reach its maximum estimated potential in another 50 years. CDM could help to achieve the maximum utilization potential more rapidly as compared to the current diffusion trend if supportive policies are introduced. 相似文献

In view of the increasing interest in the development and dissemination of technologies for harnessing new and renewable sources
of energy in India, there have also been some efforts towards their use in the domestic lighting sector. However, the cumulative
number of Solar Photovoltaic (SPV) lighting systems such as SPV lanterns and solar home lighting systems in India is far below
their theoretical potential despite government subsidy programmes. One of the major barriers is the high capital investment
in these systems. The Clean Development Mechanism (CDM) provides industrialized countries with an incentive to invest in emission
reduction projects in developing countries to achieve a reduction in CO2 emissions at lowest cost that also promotes sustainable development in the host country. SPV lanterns and solar home lighting
systems could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable
rural development. However, only two SPV projects have been submitted under the CDM so far. This study assesses the maximum
theoretical as well as the realistically achievable CDM potential of SPV lanterns and solar home lighting systems in India.
The SPV lantern project is financially viable at a certified emissions reductions (CER) price of 34 € whereas the solar home
lighting project is financially viable at a CER price of 46 €. While the maximum mitigation volume is about 35 million tonne
CO2 on an annual basis, an estimate of achievable CER levels is done using the past diffusion trends of SPV systems. We find
that annual CER volumes could reach 0.8 to 2.4 million by 2012 and 5.6 to 13.6 million by 2020. This would require that the
government sets the subsidy level for SPV lighting systems at a level that allows them to become viable with the CER revenue.
From a macro-economic point of view this makes sense if the sustainability benefits are deemed sufficiently high to warrant
promotion of this type of project.

Air pollution is increasingly recognized as a significant contributor to global health outcomes. A methodological framework for evaluating the global health-related outcomes of outdoor and indoor (household) air pollution is presented and validated for the year 2005. Ambient concentrations of PM2.5 are estimated with a combination of energy and atmospheric models, with detailed representation of urban and rural spatial exposures. Populations dependent on solid fuels are established with household survey data. Health impacts for outdoor and household air pollution are independently calculated using the fractions of disease that can be attributed to ambient air pollution exposure and solid fuel use. Estimated ambient pollution concentrations indicate that more than 80% of the population exceeds the WHO Air Quality Guidelines in 2005. In addition, 3.26?billion people were found to use solid fuel for cooking in three regions of Sub Saharan Africa, South Asia and Pacific Asia in 2005. Outdoor air pollution results in 2.7?million deaths or 23?million disability adjusted life years (DALYs) while household air pollution from solid fuel use and related indoor smoke results in 2.1?million deaths or 41.6?million DALYs. The higher morbidity from household air pollution can be attributed to children below the age of 5 in Sub Saharan Africa and South Asia. The burden of disease from air pollution is found to be significant, thus indicating the importance of policy interventions. 相似文献
