G8 environment ministers: halve emissions by 2050
Environment ministers from the G8 rich nations on Monday urged their leaders to set a global target to halve greenhouse gas emissions by 2050, a small but vital step in the fight against climate change.
But they stopped short of suggesting specific interim targets ahead of 2050, a key demand of developing countries in tough U.N.-led talks to forge a new treaty on global warming by the end of next year.
