文摘 减排责任的区域分解需要科学评价各地区的排放责任。碳足迹可以全面客观地评价为满足消费而进行的生产的生命周期碳排放水平,除了生产过程的直接碳排放,也包括生产过程中所消耗的中间产品的隐含碳排放。应用2007年各省区投入产出模型和2002年中国省区间投入产出模型,定量测算了各省区的碳足迹和省区间的碳排放转移。结果显示,各省区之间碳足迹和人均碳足迹存在显著的差异。碳足迹较大的省份为经济大省,主要分布在北方地区;人均碳足迹较高的省份主要是北京、上海等中心城市和能源富集区域及重化工基地;中国存在着从能源富集区域和重化工基地分布区域向经济发达区域和产业结构不完整的欠发达区域的碳排放空间转移。上述结果表明,人均碳足迹高的经济发达省份应承担较大的减排责任,能源富集区域和重化工基地分布区域有相当一部分的碳排放是为沿海发达省份和产业结构不完整的欠发达省份提供电力、原材料等高碳产品所致,减排责任的区域分解需要考虑碳排放空间转移的因素,适当减轻能源富集区域和重化工基地分布区域的减排责任,或使沿海发达省份向能源富集区域和重化工区域提供资金和技术上的扶持,帮助这些区域提高能源利用效率,减少碳排放。
其他语种文摘 Obligation assignment of carbon emission reduction needs to evaluate carbon emission charge by taking into account interregional transfer of carbon emissions. Carbon footprint, as a concept of carbon emission measurement, can evaluate life cycle carbon emissions of production and service to meet final demand. It should include direct carbon emissions caused by fossil energy as well as indirect carbon emissions induced by intermediate products production. This paper aims to estimate carbon footprint of each province and inter-provincial transfer of carbon emissions in China based on an input-output approach and China IRIO 2002 database. The results indicate there are significant differences of carbon footprint and per capita carbon footprint among provinces in China. The provinces with higher carbon footprint, mainly located in northern China, have large economic scale. The provinces with high per capita carbon footprint include developed metropolitan regions and energy-rich regions with a high proportion of energy intensive sectors. Interregional transfer of carbon emissions has emerged from energy-rich regions with a high proportion of energy intensive sectors to developed coastal regions and developing regions with incomplete industrial systems. The results imply developed coastal regions should bear more obligation of carbon emission reduction. As a significant amount of carbon emissions of energy-rich regions with a high proportion of energy intensive sectors is induced by provision of energy intensive products for developed coastal regions and developing regions with incomplete industrial systems, interregional transfer of carbon emissions should be taken into account for regional obligation assignment of carbon emission reduction. It can be considered to reduce obligation of carbon emission reduction for those energy-rich regions with a high proportion of energy intensive sectors. Otherwise, a compensation mechanism should be considered for developed coastal provinces to provide financial and technological aid to energy-rich regions with a high proportion of energy intensive sectors for improvement of energy use efficiency and reduction of carbon emissions.
