摘要
2007年5月4日,IPCC第三工作组在泰国曼谷发布了第四次评估报告《气候变化2007:减缓气候变化》的决策者摘要及主报告。报告综合评估了2001年以来有关减缓气候变化的最新研究成果,考察分析了中短期(2030年前)和长期(2030年后)温室气体的排放情景、减排潜力、成本范围,以及稳定大气温室气体(GHG)浓度水平的可能选择。报告总体认为,未来温室气体排放取决于发展路径的选择,现有各种技术手段和许多在2030年以前具有市场可行性的低碳和减排技术,将以较低的成本实现有效减排;在2030年以后将温室气体浓度稳定在较低水平的成本并不高,但需要国际合作,采取一致行动,并认为可持续发展与温室气体减排可以相互促进。
The Working Group III of the IPCC announced the summary for policy makers and the underlying fourth assessment report Climate Change 2007： Mitigation of Climate Change, on 4 May 2007 in Bangkok. This report provides a comprehensive review and state-of-the-art assessment of the scientific, technical, environmental, economic, and social aspects of the mitigation of climate change by updated developments in the literature during the last five years. In the report, examination is made into the greenhouse gas （GHG） emission scenarios in the short and medium term （till 2030） and in the long term （beyond 2030）, mitigation potential, cost ranges, and possible choices for stabilization of GHG concentration in the atmosphere. In general, a conclusion is drawn in the report that future GHG emissions are highly dependent on development pathways. Many currently available technologies and those that would be commercially viable technologies by 2030 can reduce emissions in a cost effective manner. Stabilization of GHG concentrations in the atmosphere after 2030 can be kept at relatively low level with comparatively lost cost with respect to their impact on GDP growth. However, greater cooperative efforts are required for effective emissions reduction. Sustainable development and climate change mitigation can be mutually reinforced and synergies are required.
