G8 leaders agree climate change target

Leaders of the world’s biggest emitters of carbon dioxide today agreed to seek measures to limit global warming to 2C, but failed to seal a deal on reductions in greenhouse gases.

The declaration, which is the first time America, China and India have all put their names to a target for limiting climate change, came at the G8 summit in Italy which also saw agreement on renewed efforts to conclude a key global trade deal by 2010.
