Economic and Technical Study on Reducing Carbon Dioxide Emissions
经济层面和技术层面的碳减排研究

It is certain that the global climate has changed a lot. Carbon dioxide is an important greenhouse gas. Carbon dioxide reduction is an important measure to mitigate the greenhouse effect and it becomes a hotspot of climate change researching. This paper introduces systemically and generally the study on reducing carbon emissions from these aspects of IPCC & country groups, economy and professional technology. On the policy layer, this paper introduces the activities of IPCC and country groups differentiated from their opinions on KP. In economic aspect, it describes some quantified models, mechanism of carbon tax and ancillary effects of carbon reduction. Professional technologies takes the key role to reduce carbon dioxide emissions. This paper introduces the study on carbon activity including carbon sink, carbon stock, carbon cycle, the application of industrial technologies of reducing carbon dioxide emis-sions, and so on. Lastly, this paper puts forth some measures in brief on the research of reduction of carbon dioxide emissions in China.
