我国煤炭统计体系及二氧化碳排放核算研究

Study on Coal Statistical System and CO_2 Emissions Calculation System in China

核算我国煤炭相关二氧化碳排放量对于我国温室气体核算,具有重要意义。本文详细分析了我国煤炭相关统计体系,指出基于煤炭消费侧的统计数据无法满足建立我国煤炭相关二氧化碳排放核算体系的要求。基于目前煤炭生产和销售的统计体系现状,提出相应的核算方法,并据此给出了我国2005年煤炭相关二氧化碳的排放结果,分析了其不确定性。从长远来看,应逐步建立能够与国际相关温室气体排放清单核算要求相符合的煤炭统计体系,提高我国煤炭相关二氧化碳排放量核算的质量。

Chinese coal related CO2 emissions calculation plays an important role in the total GHG emissions calculation. This study focuses on the Chinese coal related statistical system. We concludes that the coal consumption statistical data cannot satisfy the needs for establishing the coal related CO2 emissions calculation system. Then we propose another calculation method for coal related CO2 emissions based on the current coal production and sales data, based on which we calculate the coal related CO2 emissions in 2005 and give the uncertainty result. From the long-term scale, China should establish coal calculation system that can satisfy the needs for coal related CO~ emissions calculation system.
