国际英语新闻：UN chief urges climate change on G8, G20 agenda

Canada’s Conservatives government led by Prime Minister Stephen Harper has rejected the 1998 Kyoto Protocol, which was negotiated by the previous Liberal government and calls for a six per cent reduction of greenhouse gases by 2020 based on 1990 levels.

Harper has pledged a 17 per cent reduction by 2020, based on 2005 levels, which is in line with U.S. targets but not as tough as Kyoto.

Supporting the Copenhagen Accord, he also has pledged that Canada would contribute a fair share to a global fund to help developing countries to reduce their emissions.
