G-8 endorses halving global emissions by 2050

The Group of Eight leading industrial nations on Tuesday endorsed halving world emissions of greenhouse gases by 2050, edging forward in the battle against global warming but stopping short of tough, nearer-term targets.

The G-8 countries — the United States, Japan, Russia, Germany, France, Britain, Canada and Italy — also called on all major economies to join in the effort to stem the potentially dangerous rise in world temperatures.
