With this so-called consumerresponsibility method, the emissions embodied in imported electricity were calculated with source-specific emissionfactors. Using the new method, the CO2emissions in 2005 and 2010 were estimated. Compared with those derivedfrom the producer responsibility method, the power exporters’ emissions decreased sharply. The emissions from thepower sector in Inner Mongolia with the largest exported electricity, decreased by 109 Mt CO2in 2010. The value isequivalent to that from Shaanxi’s power production or Canada’s power and heat production in 2010. In contrast, thepower importers’ emissions increased sustantially. The emissions from the power sector in Hebei, the largest powerimporter of China, increased by 74 Mt. Emissions of Beijing increased by 60 Mt 320 in 2010. Thus, we suggestthat the Chinese government should take the emissions calculated from consumption perspective into account whenformulating and assessing local CO2emission reduction targets.Key words power sector; CO2emissions; consumer responsibility method; producer responsibility methodMa Cuimei1, 2, Ge Quansheng2
