American climate negotiators refused to back down in their opposition to mandatory cuts in greenhouse gas emissions Thursday, even as a U.S. Senate panel endorsed sharp reductions in pollution blamed for global warming.
The United States, the world's largest producer of such gases, has resisted calls for strict limits on emissions at the U.N. climate conference, which is aimed at launching negotiations for an agreement to follow the Kyoto Protocol when it expires in 2012.
That stance suffered a blow when the Senate Environment and Public Works Committee passed a bill Wednesday to cut U.S. emissions by 70 percent by 2050 from electric power plants, manufacturing and transportation. The bill now goes to the full Senate.
U.S. climate negotiator Harlan Watson, however, said that would not impact Washington's position at the international gathering in Bali.
