President Obama’s second-term push to complete greenhouse gas regulations won’t revive prospects for climate change legislation on Capitol Hill, a top Democrat said.

“The Republicans who run our committee deny the science. So there’s not hope for legislation,” said Rep. Henry Waxman (D-Calif.), the top Democrat on the House Energy and Commerce Committee, on the C-SPAN program “Newsmakers” airing this weekend.

Some advocates have speculated that as regulations draw closer, coal-reliant power companies and other fossil fuel interests would become increasingly open to climate legislation that’s currently dormant on Capitol Hill.

Congress could likely provide polluters more flexibility and incentives that regulators acting under the Clean Air Act that was authored four decades ago.

But Waxman, who co-authored the sweeping climate bill that narrowly passed the House in 2009 but died in the Senate, said Republicans would not be interested.
