内蒙古碳排放核算的实证分析

An Empirical Analysis of Carbon Accounting for Inner Mongolia Autonomous Region

以内蒙古投入产出表中的国民经济42个部门为基础,另增加居民为核算部门,运用IPCC(2006)的方法理论对碳排放进行核算,并以内蒙古为例进行了实证分析.该核算方法不仅与现行的国民经济核算体系的统计口径一致,还在固定源及移动源燃烧核算的基础上,增加了一直被忽略的农业、废弃物及工业过程和产品使用部分,能够全面、完整地反映内蒙古各核算部门的碳排放量.实证分析发现,在内蒙古的各个核算部门中,居民部门产生的碳排放量所占比例最高,为25.7169%;其次是电力、热力的生产和供应业部门与金属冶炼及压延加工业部门,排放量所占比例分别为18.4775%和16.3682%;从排放总量的角度来看,能源的碳排放总量最大,为26952.776万吨所占比例为54.94%.

Selecting forty-two national economic sectors in the input-output table of Inner Mongolia, adding residents into the basic accounting structure, the IPCC （2006） methods on carbon accounting are used to calculate the total carbon emission in the region. The accounting methods is not only consistent with the statistical standards of the current national economic accounting system, but also inclusive of stationary combustion sources, mobile sources, and the carbon emissions from the agriculture, waste and industrial processes, which have been neglected in the previous studies. The study found that among all of the accounting sectors of Inner Mongolia, the resident sector produces the highest amount of carbon emissions with 25. 7169%, followed by electricity-heat production and supply sector, and metal smelting and rolling processing sector with 18. 4775% and 16. 3682% respectively; the total emission from energy consumption is the highest, up to 269, 527,760 tons, and accounts for 54. 94%.
