基于EIO-LCA的隐性碳排放估算及地区差异化研究——江浙沪地区隐含碳排放构成与差异

Study on the Differentiation of Regional Implicit Carbon Emissions Based on EIO-LCA——Composition and Differences of Implicit Carbon Emission in Yangtze River Delta

基于中国2007年地区经济投入产出表及其生命周期评价(EIO-LCA)模型,构建江浙沪3地的部门温室气体排放矩阵,从直接排放和隐性排放2个视角分析碳排放在部门间的分布结构。结果表明:(1)电力、热力的生产和供应业的直接排放量最大;(2)工业的隐性排放量最大,且其隐含排放量主要源自生产链中的电力、热力的生产和供应业;(3)上海为碳排放净输出地区,江苏为碳排放净输入地区。

Building the matrix of departments＇ carbon emissions in Jiangsu, Zhejiang and Shanghai based on the 2007 economic input- output table and Economic Input- Output Life Cycle Assessment （EIO- IGA） model. Analyzing the structures of distribution and differences between the departments by two aspects including the direct emissions and the implicit emissions. The resuhs show that： （1） Direct emission from Producing and Supplying Electricity and Heat department is maximum; （2） The maximuurn implicit emission is from Industry department, and its implicit emission is mainly from Producing and Supplying Electricity and Heat department; （3） Shanghai is the carbon exporting city, Jiangsu is the carbon importing province.
