Abstract:With the rapid development of Chinese economy and the excessively relying on the fossil energy,the emission of CO2 is becoming the serious issue. This will cause a heavy pressure on the nature environment and the international society. In order to reduce the emission of CO2,the current status of Chinese CO2 emission sources should be investigated first. In this paper,the total amount of CO2 emission from the major industrial sources(power plants,cement production,steelworks,refineries,ethylene,ammonia,ethylene oxide and hydrogen) in China is estimated to be 29.631 5×108 t with the production data of the above various plants. Meanwhile,the distribution maps of the eight sorts of sources,large-scale sources and high concentration sources are presented. Power plants,cement and steel are the top three CO2 emitters,which account for about 91.7% of the total emissions. Using the same method,the emissions of 1998–2002 of these three plants are calculated according to the open statistic data. It can be concluded that the emissions are increasing remarkably at the average rate of 9.7% since 1998.
