城市产业部门CO2排放三层次核算研究
Three-level CO2 Emission Accounting of Urban Industrial Sectors
摘要
Abstract
As the center of human production and life, urban areas emitted more than 75% of the total greenhouse gas (CHC) , in which, CO2 produced during the energy consumption and non-energy processes from industrial sector accounted for a large proportion. In this study, life cycle CO2 emission from industrial sector, which was categorized into three level emissions, was accounted based on input-output model the paper concluded that CO2 emissions were underestimated by the existing accounting methods which are the direct emissions of final energy combustion and the indirect emissions of electricity and steam purchases. And then, input-output life cycle assessment method was chosen to evaluate the upstream carbon emissions of 28 economic sectors of Chongqing. We could see that the emissions of each sector in Chongqing increased year by year, but the overall carbon intensity declined. Meanwhile, seven sectors, namely, coal mining and dressing, nonmetal minerals mining and dressing, nonmetal mineral products, electricity, steam production and supply, chemical industry, smelting and pressing of metals, transportation, storage, postal and telecommunication services, are key sources of CHC emissions in Chongqing. In addition, while the life cycle CO2 emission of transportation equipment sector took the largest share, but the carbon intensity was relatively smaller. And the sector of transportation equipment was one of the advantageous industries in Chongqing, so it should be actively developed in future.关键词
