Abstract：Based on regional carbon emissions compilation for electric vehicles,This paper constructs a set of scientific and comprehensive regional carbon emission index system for EVs.Covering four dimensions of regional development,low-carbon transport,vehicle operation and electricity production,we measure 12 key indicators of carbon emissions from EVs and select six representative provinces in China for case verification.The results show that:① the regional carbon emission index of EVs in Beijing reached the highest score in 2019,and showed a rapid downward trend in 2020 due to the improvement of power grid development level and the COVID-19 pandemic;② according to the regional carbon emission index results of representative provinces such as Beijing,Shanghai,Guangdong,Zhejiang,Jiangsu and Tianjin,it is found that the overall carbon emission of EVs in the region is more affected by economic development,residents'life quality and ecological environment;③ reducing residents'unnecessary travel demand,reducing grid transmission losses and increasing the proportion of clean energy generation are conducive to reducing the regional carbon emission level of the EV industry.The regional carbon emission index of EVs proposed in this paper can effectively quantify the comprehensive carbon emission level of EVs in different regions,identify the advantages and disadvantages of low-carbon development of EV industry in different regions,and provide a reference for seeking path optimization of low-carbon transformation for EV industry at the regional level.
