In a step that reflected deep partisan divisions in the Senate over the issue of global warming, Democrats on the Environment and Public Works Committee pushed through a climate bill on Thursday without any debate or participation by Republicans. The measure passed by an 11-1 vote, with the support of all the Democratic committee members except Sen. Max Baucus of Montana. The seven Republicans boycotted the committee meetings this week, saying they had not had sufficient time to study the bill and demanding that the Environmental Protection Agency conduct a thorough study of its economic costs and benefits. Sen. Barbara Boxer, D-Calif., the committee's chairwoman and co-sponsor of the bill, employed a rarely used exception to customary committee rules. She conducted three days of hearings last week on the 959-page measure, known as S. 1733, but there was no debate on the measure. Boxer said that the EPA had already conducted a preliminary analysis of the bill and that further study would be costly and duplicative. She said it was necessary to bypass the committee's rule that required Republican participation because of Republican intransigence and the urgency of the issue. 'A majority of the committee,' she said in a statement, 'believes that S. 1733, and the efforts that will be built upon it, will move us away from foreign oil imports that cost Americans $1 billion a day; it will protect our children from pollution, create millions of clean energy jobs, and stimulate billions of dollars of private investment.' The senior Republican on the environment committee, Sen. James M. Inhofe of Oklahoma, said the bill would harm the American economy and cost millions of jobs. He said the Democrats' decision to ram the bill through 'marked the death knell' of efforts to enact a comprehensive climate change bill. Baucus' vote against the bill was another ominous sign. He is the chairman of the Finance Committee and a senior member of the Agriculture Committee, both of which will have major input in any final climate and energy legislation. He said the bill's emission reduction targets were too ambitious and its agriculture provisions too weak. He said the measure had a long way to go. 'This is a first step,' he said Thursday. 'There will be many other steps.'
