Study Of Assessment On Environmental Benefits Of CO₂-ECBM Project

The world has paid attention to global warming. We have taken cognizance of the serious aftereffect of the climate change. We must take action to settle the environmental problem, or else it is threatening entironment on the earth and human being.China is the second country of CO₂ emission in the world. As the economic development in China goes on, the emission of CO₂ will be more and more. According to the estimation, China will be the first country of CO₂ emission in 2020, exceeding the USA.China is the first CH4 emission country in the world because of excavating coal. CH4 is a sort of greenhouse gas. Its greenhouse effect is 21 times than CO₂'s. Its contributing rate of greenhouse effect is 15%,just inferior to CO₂.In other to abate the climate change, we must mitigate CO₂.However, along with economic development, CO₂ emission will be increase. China is the biggest developing country, being approving the Kyoto Protocol (hereinafter referred to as"Protocol") earlier. China is confronted with the conflict of development and mitigation.CO₂-ECBM is environmental project. The project can reduce the emission of greenhouse gas and environmental pollution, and solve the contradiction between mitigation and economic development. It has enormous environmental benefits. There are various methods of evaluation for coalbed methane development. This paper analyses resource factor, economic factor and technology factor, based on characteristic of CO₂-ECBM. Based on CDM (Clean Development Mechanism), a model for CO₂-ECBM environmental benefits evaluation is proposed, including qualitative and quantitative. The research results showed that running the system models makes it possible.Increment evaluation method is adopted to calculate direct benefits. Indirect benefits evaluation model is proposed. Benefits on greenhouse gas mitigation and coal mine danger reduction are calculated quantitatively. Indirect benefits on saving energy resources, changing energy resources structure, enhance standard of living are analyzed qualitatively.Being a developing country, China constitute scheme to deal with climate change. During 2006²010, consumption of energy resources per GDP will be reduce by 20%.Premier Wen Jiabao bring forward that we should economize resources ,reduce consumption and protect environment. This paper put forward five advices: perfecting environmental benefits evaluation system of CDM project, developing business of CO₂ mitigation; enlarging production of CO₂-ECBM; developing research of storage of CO₂; changing energy resources structure; adjusting structure of economic and industry, updating technology.CO₂-ECBM is already a hot problem overseas. In China, the research of CO₂-ECBM is initial stage. This paper brings environmentalism into coalbed methane development project and lays scientific foundations for decision-maker.
