作为世界上最大的CO2排放国，中国的CO2排放问题已成为国内外研究者关注的热点问题之一。因此，分析我国碳排放的现状十分重要。在绘制了2012年中国碳流量图表后，基于IPCC碳排放清单方法和中国能源平衡表，详细描述了中国碳流量的现状，并比较了2008年至2012年中国碳流量的变化特征。结果表明，CO2排放总量的75.12%主要流向几个行业，如钢铁行业和终端子行业中的化工行业。尽管中国的热电效率在过去四年中大幅提高，但由于中国对热能和电力的巨大需求，热能和电力生产部门的排放量仍在增加。在黑色金属和化学工业部门，CO2排放主要来自能源，而在非金属矿产部门，CO2排放主要来自过程CO2排放。在不同的终端子行业中，CO2流动的主要载体不同，因此，相关的CO2减排政策也应该有针对性。此外，本文还提出了一些有价值的建议。
As the world’s largest CO2emitter, China’s CO2emissions have become one of the most popular issues concerned by domestic and foreign researchers. Therefore, analysis of the current status of China’s carbon emissions is very important. After drawing a chart of China’s carbon flow in 2012, based on the IPCC carbon emission inventory method and China’s energy balance table, this paper gives a detailed description of the current status of China’s carbon flow and compares the changing characteristics of China’s carbon flow between 2008 and 2012. The results show that 75.12% of total CO2emissions flow mainly into several sectors, such as ferrous sectors, and the chemical industry in the terminal sub-sectors. Although China’s thermoelectric efficiency increased dramatically during past four years, emissions from the heat and power production sector are still increasing due to China’s large demand for heat and power. In the ferrous metal and chemical industry sectors, CO2emissions are mainly energy-related, while in the non-metallic mineral sector, CO2emissions are mainly from process CO2emissions. In different terminal sub-sectors, the main carriers of CO2flow are different, thus, related CO2reduction policies should also be targeted. In addition, some valuable suggestions are given in this paper.
