"Most people in the West know that the poor world contributes to climate change, though the scale of its contribution still comes as a surprise. Poor and middle-income countries already account for just over half of total carbon emissions (see chart 1); Brazil produces more CO2 per head than Germany. The lifetime emissions from these countries’ planned power stations would match the world’s entire industrial pollution since 1850.
Less often realised, though, is that global warming does far more damage to poor countries than they do to the climate. In a report in 2006 Nicholas (now Lord) Stern calculated that a 2°C rise in global temperature cost about 1% of world GDP. But the World Bank, in its new World Development Report*, now says the cost to Africa will be more like 4% of GDP and to India, 5%. Even if environmental costs were distributed equally to every person on earth, developing countries would still bear 80% of the burden (because they account for 80% of world population). As it is, they bear an even greater share, though their citizens’ carbon footprints are much smaller"
