A bicameral group of Democrats floated draft legislation Tuesday that would impose a per-ton fee on carbon emissions from the nation’s largest polluters, such as electricity generators and petroleum refineries.

“For far too long, carbon polluters have pushed the true cost of their pollution onto the American people in the form of dirty air, acidified water, and a changing climate,” said Sen. Sheldon Whitehouse (D-R.I.), who is spearheading the effort with House Energy and Commerce ranking member Rep. Henry Waxman (D-Calif.), Rep. Earl Blumenauer (D-Ore.) and Sen. Brian Schatz (D-Hawaii).

The bill is not likely to go anywhere in the GOP-controlled House, nor in the Senate, where some centrist Democrats would join Republicans to oppose measures that affix a fee to carbon.

Still, the bill indicates a growing willingness among some Democrats to take advantage of a resurgence of climate change awareness after it spent years on the political backburner.
