中国省域间碳排放责任共担与碳减排合作

Responsibility Sharing of China’s Inter-provincial Carbon Emission and Cooperation in Carbon Reduction

通过构建区域间双边碳转移测算模型,本文以中国大陆省级行政单元为对象测算了省域最终需求和出口引致的碳转移,并通过设计合理的分配因子来实施省域间碳排放责任共担。结果表明:本省域最终需求引致的碳排放约占全部生产侧碳排放的41%,外省域最终需求引致的碳排放占比约为31%,出口引致的碳排放占比约为22%。省域最终需求和出口引致的碳转移呈现从京津地区、东部沿海和南部沿海的省域向北部和中部地区的省域转移,其中各省域出口引致的净碳转移量平均占全部净碳转移量的43.7%,出口是引致省域间碳转移的重要因素。基于省域间碳排放责任共担结果,论文提出对重点减排省域实施"约束+补偿"的碳减排合作模式,同时控制碳排放的生产端和消费端,减少碳排放和碳转移量。

By constructing a calculation model of inter-regional bilateral carbon transfer, this paper measures the carbon transfer caused by the inter-provincial demand and export, and designs allocation factors to implement responsibility sharing of carbon emissions.The results show that during the study period,the carbon emissions caused by the inner-provincial demand accounted for about 41% of the total production-based carbon emissions, the carbon emissions caused by the inter-provincial demand accounted for about 31%, and the carbon emissions caused by the export accounted for about 22%. The path of carbon transfer caused by the inter-provincial demand and export is from the provinces located in Beijing-Tianjin,eastern and southern coastal areas to the provinces located in northern and central areas. The net carbon transfers induced by export accounted for 43.7% of the total carbon transfers. Therefore, the export is an important factor which has caused a lot of inter-provincial carbon transfers. Based on the results of responsibility sharing of inter-regional carbon emissions, we propose to implement a "constraint and compensation" cooperation mode in carbon reduction within the main carbon emission provinces in order to reduce carbon emissions and carbon transfers by controlling the production and consumption of carbon emissions simultaneously.
