WASHINGTON -- A Senate committee cleared its version of a climate and energy bill, despite a Republican boycott of the vote and a "no" from powerful Montana Democrat Max Baucus.

The Senate Environment and Public Works Committee's 10-1 vote to approve the climate proposal may have little long term significance in shaping the final bill. Negotiations to shape a Senate climate bill have already moved beyond the committee and its chairwoman, Sen. Barbara Boxer (D., Calif.). Sen. John Kerry (D., Mass.) is working with Sen. Lindsey Graham (R., S.C.) and Connecticut independent Sen. Joe Lieberman to develop a compromise package that would give more benefits to the oil and nuclear-power industries.

Republican members of the committee boycotted the vote to protest a lack of a complete analysis of its potential economic impact. Republicans have called the Senate climate measure and a similar measure passed by the House of Representatives a "tax" that the country can ill-afford at a time of high unemployment and economic uncertainty.

It isn't clear how much progress Senate Democrats will make on the climate issue before a United Nations conference in Copenhagen in December, where global leaders are supposed to discuss a new international treaty on climate change.

Mr. Baucus's no vote highlighted the doubts among Democrats from states dependent on coal and manufacturing about the Boxer proposal.

The proposal approved by Environment and Public Works committee Democrats calls for a 20% cut in greenhouse-gas emissions by 2020. Lawmakers from coal-dependent states say that target will hurt their economies. When the House of Representatives cleared a companion measure earlier this year, it was able to win support for reductions of only 17% by 2020.

Lawmakers from some manufacturing states have told President Barack Obama that any climate bill should allow for tariffs on goods from countries that don't adopt climate policies comparable to those of the U.S.

Farm interests are also flexing their muscles as negotiations continue, pushing for bigger financial rewards for activities that reduce greenhouse-gas emissions.
