有必要确定包括印度、中国和其他主要发展中国家在内的各国在将大气中温室气体总存量保持在450 ppm（二氧化碳当量）以下方面的作用，这反过来又有50%的可能性将全球气温上升保持在2°C以下。使用基于gams的排放模型分析了附件一国家，大型发展中国家和其他国家未来的二氧化碳排放量。这一分析尖锐地强调了发达国家对全球变暖的历史责任，以及它们有义务大幅减排以减缓气候变化。此外，中国和印度等发展中大国也需要为减缓气候变化做出强有力的贡献。有人认为，这种必要性表明，碳抵消将成为发展中国家的“双重负担”，也是工业化国家关键迁移技术创新的主要抑制因素。分析表明，印度需要一个替代性的气候政策，承认积极主动的减缓气候变化行动，同时确保发达国家不会将负担转嫁给全球南方，否则将严重限制其发展选择。
It is necessary to determine the role of various nations, including India, China and the other major developing countries in keeping the total atmospheric stock of greenhouse gases below 450 ppm (carbon dioxide equivalent) which, in turn, would provide a 50% probability of keeping the global temperature increase below 2°c. An analysis of future emissions of co2 in Annex I countries, large developing nations and other nations is done using a gams-based emission model. This analysis underlines sharply the historical responsibility of the developed nations for global warming and their duty to cut emissions drastically to mitigate climate change. Also large developing nations like China and India also need to contribute strongly to mitigation. It is argued that this necessity makes evident that carbon offsets will act as “double burden” on developing nations, as also a major disincentive to innovation in critical migration technologies in the industrialised world. The analysis implies that India needs an alternative climate policy that recognises proactive action for climate change mitigation while ensuring that the developed nations do not pass on their burden to the global South, which would otherwise seriously restrict its development options in the process.
