China City CO2 emission dataset: based on the China high resolution emission gridded data
摘要
Abstract
The China City CO2 emission dataset are built based on China High Resolution Emission Gridded Data (CHRED) with 1 km spatial resolution, by a unified framework and data processing methods.These data are completely open for scientific study and policy making.The scope 1 (direct) and scope 2(indirect) emissions are calculated by internationally accepted methods.The official energy statistical data of 5 cities (Beijing, Tianjin, Shanghai, Chongqing and Guangzhou) are used for calculation of reference level emission, to check the uncertainties of the emission dataset.The comparison shows that the discrepancies between the reference level and dataset for each city are less than 10%.The spatial pattern of emissions of cities shows that the cities in north are higher than cities in south, and cities in middle and east of China are relatively higher than cities in other regions.Most of the cities with high CO2 emissions are located in North China, East North China and coastal region of East China.According to the correlation analysis between 8 sectors (industrial energy, industrial process, agriculture, service, urban household, rural household, transport and scope 2) in cities, the emissions of urban household and transport are most related (p<0.001), while emissions of industrial process and service are no significant correlation.With completeness and development of China city CO2 emission dataset based on CHRED, it will not provide fundamental data for scientific research, but also effectively support the lateral comparative assessment and benchmarking of cities' emissions in China.关键词
