As climate change will have serious effects on the social and economic development and everyday, living of people in the world, many of the countries and governments are taking untiring efforts to combat climate change. As one of the important mechanisms of reducing greenhouse gas （GHG） emissions in the Kyoto Protocol, Clean Development Mechanism （CDM） has not only provided chance for developed countries to fulfill greenhouse emission reduction obligations, but also provided an opportunity for developing countries to combat climate change under the sustainable development frame. The dual objectives of developed countries＇ GHG emissions＇ reduction obligation achievement and developing cotmtries＇sustainable development will be achieved under the CDM. As a country with responsibility; China has been positively developing CDM projects and promoting energy saving and emissions reduction during the three yeors after the Kyoto Protocol came into force, and CDM projects development has always been in the front tank in the world. However; as the vast clime within China, notable differences occur in different regions. In order to promote the CDM development in China, it is necessa^T to have regional CDM capability construction in accordance with the practicality in different regions. Based on the Slat Analysis of developed CDM projects and current CDM development status in China, problems in the CDM development of China, including the inefficiency in small and medium-sized CDM Projects＇ development, over centralization of CDM development scope and especially the differentiated provincial CDM projects developing capability are pointed out in the paper： What＇s more, reasons for the problems are analyzed from fire leading.factors, including policy orient, information asymmetry and weak CDM capability, In order to promote CDM projects development in China, a new CDM capability, construction model is put forward in the paper.展开更多

On the other hand, carbon dioxide might be considered as a valuable and renewable carbon source. One approach to reduce carbon dioxide emissions could be its capture and recycle via transformation into chemicals using the technologies in C1 chemistry. Despite its great interest, there are difficulties in CO2 separation on the one hand, and thermodynamic stability of carbon dioxide molecule rendering its chemical activity low on the other hand. Carbon dioxide has been already used in petrochemical industries for production of limited chemicals such as urea. The utilization of carbon dioxide does not necessarily involve development of new processes, and in certain processes such as methanol synthesis and methane steam reforming, addition of CO2 into the feed results in its utilization and increases carbon efficiency. In other cases, modifications in catalyst and/or processes, or even new catalysts and processes, are necessary. In either case, catalysis plays a crucial role in carbon dioxide conversion and effective catalysts are required for commercial realization of the related processes. Technologies for CO2 utilization are emerging after many years of research and development efforts.展开更多

The Chinese electricitysector places centrally in the country’s economy andenvironment, being a significant contributor to theacid rain and air pollution problems that plague manyof China’s cities and regions, and therefore a focusof many related energy and environmental policies.China’s electricity sector has also been the subjectof a number of economic analyses that have showedthat it contains the highest potential for clean energyinvestment through the Clean DevelopmentMechanism of any economic sector in China. Thismechanism, through the active participation frominvestors in more industrialized countries, can helpalleviate the environmental problems attributable toelectricity generation in China through advancingsuch technology as wind electricity generation, cleancoal technology, high efficient natural gas electricitygeneration, or utilization of coal mine methane. Inthis context, the Clean Development Mechanismalso compliments a range of environmental and energypolicies which are strategizing to encourage thesustainable development of China’s economy.展开更多

From a total of sixty- five projects ideas, forty-four achieved registration under the CDM EB while the rest remained approved at national level (12), under evaluation (2), suspended (5) or rejected (2). Most of the projects focused on the generation of electricity from renewable energy, mainly wind energy and the use of landfill gas and methane for energy. Emissions reductions achieved 33.4% of the expected CERs up to 2012 with strong differences among sectors. Results demonstrated that under the current Argentina’s energy policy framework, the income by the selling of CERs covered less than 6% of the incremental costs for renewable energy projects. A sensitivity analysis to evaluate the impact of CDM in the coverage of incremental costs for renewable energy based on the prices of both the energy in the local market and the CER demonstrated that the best conditions would only cover 15% of those costs. The contribution of CDM to technology transfer in Argentina was minor considering that 45% of the projects qualified as type III where technological learning and capacity building were limited at the level of operation and maintenance of a foreign technology. Domestic and external barriers that prevented a better performance of CDM projects in terms of GHG mitigation, technology transfer and the contribution to a sustainable development were also analyzed.展开更多

The innovation of this paper lies in： Introducing necessary factor （the developing countries pricing power） and the application of several international representative indicators to un- derline the ＂world＂ nature of CDM; utilizing different econometric models to obtain noteworthy and more robust results. The authors test the theoretical findings with multiple stationary time series from the launch of CDM to present （2008-2016）. The results reveal that sCER price fluctuation shows the characteristic of asymmetry and substantial persistence. There is a strong statistically significant relationship between macroeconomic conditions, coal and oil prices, with the price of sCER. The authors discover that the pricing power of developing countries indeed has a clear but small impact on the sCER price changes, whereas the price elasticity of supply under CDM is so weak. The interaction between EU emission allowances （EUAs） and sCER presents a shift from dependency to substitution.展开更多

Based on investigation, energy consumption forecast and economic analysis of future technology options, the technology benchmark and site specific baselines for both retrofit projects and new heating projects have been discussed. The results indicate that fuel switching from coal to natural gas can meet the additionality criteria in many cases and will be the main type of CDM project. In addition, it also proves that the technology benchmark and the case by case baseline setting approach are applicable for future CDM cooperation projects on heating in Beijing.展开更多

The case showed that the optimized crops planting scheme and cows breeding scheme obtained from the optimal model was reasonable with relatively preferable overall performance. In the context of meeting economic benefits and fertilizer, electricity demand, [231 287.8, 273 312.7] t of CO2 could be absorbed and fixed, which had increased by [12.94, 33.46]% compared with the feasibility scheme of case project and provided technical support for making the decision in CDM project.展开更多
