BRUSSELS The United States and Canada must do more than currently proposed to tackle greenhouse gases, France says in a position paper ahead of global climate talks in Copenhagen this December.
Airlines should cut emissions to 5 percent below 2005 levels by 2020, said the document, seen by Reuters on Wednesday.
It warned that Canada and the United States were not on course to cut emissions by the level needed, making it difficult for rich nations to meet the 25-40 percent collective reduction in greenhouse gases recommended by a U.N. climate panel.
"It is therefore necessary for Canada and the U.S. to take on commitments which are at least on a par with the EU's, compared with 1990 levels, particularly as gross domestic product loss resulting from this level of effort would be lower in the U.S. or Canada than in Europe," it added.
The paper, which spelt out France's vision of a fair global climate deal, said countries should base their emissions on the United Nations climate panel's most cautious scenarios.
Technology for curbing climate warming gases must also be boosted globally and shared with poor nations.
"Parties shall work toward the goal of at least a doubling of global energy-related research and development and demonstration by 2012 and increasing it up to four times its current level by 2020," said the document.
