Europe Questions U.S. on Climate

European leaders are questioning the U.S.'s commitment to reaching a global agreement on climate change, noting that the government has dragged its feet over setting specific targets for reductions in greenhouse-gas emissions. The leaders have little hope that Congress, embroiled in a health-care debate, would act on a bill before the international talks in Copenhagen in December. Some are worried Copenhagen might be a repeat of President Clinton’s mistake in Kyoto in 1997, where he signed an international agreement that was repudiated by the Senate for making too few demands on developing countries. European nations have already pledged to cut their emissions by 20 percent by 2020.
