Even as Republicans plan to push a bill through a House subcommittee tomorrow to limit U.S. EPA's authority to regulate greenhouse gas emissions, Energy and Commerce ranking member Henry Waxman (D-Calif.) continues to float the idea of the GOP and Democrats working together on a bipartisan measure that would reduce carbon dioxide emissions. Waxman has said repeatedly in recent days that he is willing to meet with Republicans "without preconditions" to craft a bill that both sides could agree on that would include incentives for low-carbon energy projects and other initiatives.
