由温室气体引起的全球气候变化已成为国际社会关注的焦点。2005年2月16日正式生效的《京都议定书》虽暂时对中国无直接的压力,但中国的温室气体排放总量仅次于美国,居世界第2位,居发展中国家的首位,这使中国在相关国际谈判中面临很大压力。2001年中国人均二氧化碳排放量为2.43t,低于世界人均水平(3.88t),但温搴气体排放呈急剧增长趋势。中国钢铁行业的二氧化碳排放量约占发展中国家钢铁工业总排放量的30%,在国内工业二氧化碳排放量在工业二氧化碳排放中仅次于电力、建材(水泥),居第3位。介绍了相关的国际动态和对我国钢铁行业温室气体排放现状分析和减排措施的研究工作。
The globe climate change caused by GHG has become world wide concerning issue. Kyoto Protocol to the United Nations Framework came into force on 16 Feb, 2005. The total amount of GHG emission in China reached 2.9 billion ton in 2000, which is in the second position next to the United State and on the top position amount the developing country. China will face great pressure on the relevant international negotiation. In 2000, the average emission of CO2 per person in China is 2.53 t, but it appears a trend of rapid increasing of emission of GHG in China. The emission of CO2 in Chinese steel industry is at the third position next to the power generation industry and cement industry. Some relevant international action and our research work in aspect of emission and mitigation of GHG in Chinese steel industry are introduced.
