The Group of Eight countries want to work with the nearly 200 states involved in U.N. climate change talks to adopt a goal of at least halving greenhouse gas emissions by 2050, according to a draft communique obtained by Reuters ahead of its formal approval. Mid-term goals also would be needed to achieve the shared goal for 2050. The statement puts the focus of fighting global warming on U.N.-led talks. European Commission President Jose Manuel Barroso said the deal represented a “new, shared vision” and kept negotiations on track for a global deal in 2009. The G8 would also unveil a series of measures to help Africa and would give USD 50 billion extra in aid by 2010.
