In case there was any doubt, the  White House on Tuesday issued a formal statement opposing a bill now  before the House that would bar the Environmental Protection Agency  from regulating greenhouse gases for the purpose of combating climate  change.
The bill, known as the Energy Tax  Prevention Act of 2011, could come up for a vote as early as Wednesday  and is almost certain to pass when it does. It has virtually unanimous  support among the Republican majority and will probably draw votes from  a few Democrats from coal and oil producing states.
 
The measure, sponsored by Representatives  Fred Upton, Republican of Michigan, and Ed Whitfield, Republican of  Washington, would overturn the E.P.A.’s finding that carbon dioxide  and other greenhouse gases pose a danger to human health and the environment.  That finding, based on a broad scientific consensus, is the basis for  pending regulation of carbon emissions from vehicles and large stationary  sources like power plants, factories and refineries.
 
Republicans assert the new rules  are a hidden energy tax that will significantly raise production costs  and drive jobs offshore.
Administration officials have spoken  out against the bill in speeches and congressional testimony, but President  Obama had not formally threatened to veto it. On Tuesday, the White  House issued a strongly worded statement that erases any doubt.
