中国钢铁工业的CO_2排放估算

Estimation of CO_2 Emission in Chinese Steel Industry

对钢铁制造流程进行了碳素流运行规律解析,并对中国钢铁工业的CO2排放水平进行初步估算;同时也强调了国内外不同来源的钢铁工业CO2排放指标是不能随便拿来比较的。结果表明:虽然近年来中国钢铁工业CO2排放总量在不断增加,但吨钢CO2排放总体趋势是逐年降低的,且能源消耗引起的排放是总排放量的主要部分。

CO2 emission in Chinese iron and steel industry was estimated based on the analysis of carbonaceous-flow.It is stressed that the data or calculation approaches for specific CO2 emission estimation from different sources are not comparable.The results were indicated that although the total CO2 emission in Chinese iron and steel industry has been growing steadily,the general trend of the specific CO2 emission per ton steel has been declining from 1991 to 2007.And the CO2 emission sourced from energy consumption was accounted for the most important part of the toatl CO2 emission.
