Climate economist says developing countries must face the 'brutal arithmetic' of their responsibility for emissions
Developing countries must take on the lion's share of cuts in greenhouse gas emissions, because of the "brutal arithmetic" of climate change, one of the world's leading authorities on global warming economics has said.
Lord Nicholas Stern, former World Bank chief economist and author of the landmark Stern review of the economics of climate change, told the Guardian that poorer countries including China and India must step up to their responsibilities. "It's a brutal arithmetic - the changing structure of the world's economy has been dramatic. That is something developing countries will have to face up to," he said.
His new research shows that even if developed countries cut their emissions to zero, that would not be enough to halt runaway climate change - because emissions from rapidly industrialising economies are now so high. Greenhouse gases from emerging economies - such as China, South Korea and India, that have industrialised rapidly in the past two decades - now make up the bulk of the world's carbon emissions.
