| 摘 要： | 电力碳排放的数据质量取决于电网排放因子的准确性。为了获得用于产品碳足迹计算的电网电力碳足迹排放因子，基于电网排放因子数据和计算方法，将核算范围扩展到电力上游的燃料开采与生产、发电设施建设与退役以及电力生产过程，考虑CO2、CH4、N2O等温室气体排放，得到2020年中国区域及省级的电网电力碳足迹排放因子。结果表明：华北地区排放因子最高(1.005 t CO2e/MW·h),南方地区排放因子最低(0.470 t CO2e/MW·h),可再生能源占比高的省份排放因子低，全国排放因子显著降低。研究得到的电网电力碳足迹排放因子可为电力碳排放计算提供参考，建议在计算产品碳足迹时优先使用。

| Abstract: | The data quality of power carbon emissions depends on the accuracy of grid emission factors. In order to obtain the carbon footprint emission factors of the power grid for the calculation of product carbon footprint, based on the original data and calculation method of power grid emission factors, the accounting scope was extended to the upstream fuel mining and production, power generation facility construction and decommission and power production, taking CO2, CH4 and N2O emissions into account. The carbon footprint emission factors of the regional and provincial power grid in China in 2020 (unit: t CO2e/MW·h) were obtained. The results showed that North China has the highest emission factor (1.005 t CO2e/MW·h), south China has the lowest emission factor (0.470 t CO2e/MW·h), the provinces with a high proportion of renewable energy have the lowest emission factors, and the emission factors in nationwide scale decreased significantly. The carbon footprint emission factors of the power grid given in the study provide a reference for the calculation of power carbon emissions, which are recommended to the calculation of product carbon footprint. |
