The important factor that curbs the carbon inventory of cities of China is inventory methodology and scope. Given the insufficiency of Chinese cities carbon inventory, a system and accounting model (scopel+ scope2) as well as principles and boundaries were proposed for China. The carbon emissions in scopel and scopel+ scope2 were calculated in Chinese prefecture-level cities. The EDGAR dataset was used for the calculation of scopel carbon emissions in cities in China and the level of uncertainty was analyzed as well. The results showed that the direct carbon emission of cities in China was about 31.65% of China total emissions. The scopel+ scope2 carbon emissions in cities of China were calculated based on the GIS and RS model. The results showed that the sum of direct (scopel) and indirect (scope2) carbon emissions of cities in China accounted for 38.80% of total China carbon emissions. 展开更多
