Climate-change analysts have urged leaders of the world's largest economies to invest more of their stimulus packages in reducing greenhouse-gas emissions.

Ottmar Edenhofer, co-chair of the Intergovernmental Panel on Climate Change, and Nicholas Stern, chair of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science, are aiming their report, Towards a Global Green Recovery, at politicians attending the G20 summit in London on 2 April.

The report estimates that almost $400 billion of the total $2,610 billion in economic-stimulus packages unveiled so far by the G20 nations has been earmarked for green measures such as renewable-energy projects (see chart). China says it will devote almost 35% of its stimulus spending (about $200 billion) on green projects in 2009 and 2010, and South Korea plans to devote more than 80% of its $38-billion stimulus on green measures in the next four years.
