Abstract:An analysis was made of the present situation of carbon source and carbon sink,the distribution in different industries of carbon emission in Shanghai.The results show in the past 15 years,the carbon emission of Shanghai increases 2.54 times,and compared with the fast increase of carbon source,the amount of carbon sink in Shanghai is very small;the carbon emission from industry and the field of traffic and transportation holds over 80% of all the carbon emission in Shanghai,and the latter is becoming the first potential carbon source;manufacturing is the most important carbon source in industry,and its emission mainly distributes in metallurgy industry,petroleum industry and chemical industry.Shanghai is proposed to build a new management system of carbon emission based on the carbon emission ranking management and carbon productivity.
