COPENHAGEN (Reuters) - The world should aim to halve greenhouse gas emissions by 2050 from 1990 levels, according to a new draft text from a U.N. climate summit that makes concessions to developing nations and small island states.
"We agree that deep cuts in global emissions are required...with a view to reduce global emissions by 50 percent in 2050 below 1990 levels," it said. The target was new compared to previous drafts at a summit of 120 leaders on Friday. It said that a rise in world temperatures should be limited to 2.0 Celsius over pre-industrial times, with a review in 2016 that would also consider a tougher limit of 1.5 Celsius.
About 100 nations including small island states and least developed nations want to limit world temperature rises to 1.5 Celsius.
