摘　　要：提出一种基于各省电力消费详细来源的消费端排放计算方法,该方法使用不同来源电力的特征化排放因子估算调入电力隐含排放。对2005年和2010年各省电力部门CO_2排放量进行估算,并与生产端方法估算结果进行对比分析。结果表明:使用消费端方法计算后电力净调出省排放量下降,2010年内蒙古两种方法计算结果差值高达1.09亿t,该差值相当于陕西发电排放或加拿大发电和供热总排放;相反,使用消费端方法计算后电力净调入省排放量上升,2010年河北排放量上升0.74亿t,北京上升0.60亿t,北京两种方法计算结果相差幅度高达320%。Based on the detailed origins of each province＇s electricity consumption, a new method for calculating CO2 emissions from the power sector at the provincial level in China was proposed. With this so-called consumer responsibility method, the emissions embodied in imported electricity were calculated with source-specific emission factors. Using the new method, the CO2 emissions in 2005 and 2010 were estimated. Compared with those derived from the producer responsibility method, the power exporters＇ emissions decreased sharply. The emissions from the power sector in Inner Mongolia with the largest exported electricity, decreased by 109 Mt CO2 in 2010. The value is equivalent to that from Shaanxi＇s power production or Canada＇s power and heat production in 2010. In contrast, the power importers＇ emissions increased sustantially. The emissions from the power sector in Hebei, the largest power importer of China, increased by 74 Mt. Emissions of Beijing increased by 60 Mt （320%） in 2010. Thus, we suggest that the Chinese government should take the emissions calculated from consumption perspective into account when formulating and assessing local CO~ emission reduction targets.
