将世界主要相关研究机构和数据库(IEA、BP、EDGAR/PBL/JRC、CDIAC、EIA和CAIT)发布的中国二氧化碳排放数据与中国官方数据和估算进行比较,认为数据之间的差异来源于计算范围、方法和基础数据的不同,其中能源消费数据的差异是造成一些数据库估计值偏高的重要原因.研究认为IEA和CAIT数据与中国官方数据具有较好的可比性.建议中国加强煤炭统计工作,提高官方数据公布频率并提高清单完整性.%The paper reviews the CO2 emissions data provided by various international organizations and databases (namely IEA,BP,EDGAR/PBL/JRC,CDIAC,EIA and CAIT),and compares them with China's official data and estimation.The differences among these data are due to different scope,method and basic data,particularly the differences in fossil fuel consumption are highlighted.Compared with data from other databases,the IEA and CAIT data have the best comparability with China's official data.The paper recommends that China should enhance its coal statistics,increase the frequency of official data publication and improve the inventory completeness.
