This week has brought news of a brewing compromise on the Senate climate change bill, introduced last month amid signals that the upper chamber would give only a bit more to clean transportation than the House’s meager 1 percent set-aside of revenue from cap-and-trade carbon regulations.

The stirrings of a Senate climate deal, first reported by ClimateWire, focus on expanding the bill’s nuclear incentives and offshore drilling provisions to win over conservative Democrats and moderate Republicans.

Brad Plumer at The New Republic offers a good rundown on why such a compromise wouldn’t be as bad as it might sound to some progressives. But even if it still sounds bad, there’s more heartening climate news to relay: Sens. Michael Bennet (D-CO) and Bill Nelson (D-FL) this week have signed onto legislation that would require transit and other clean transport to get 10 percent of the money raised by regulating carbon.

The measure in question, often referred to as "CLEAN TEA," has already won over half the Democrats on the Senate environment committee. Nelson would be its second sponsor on the Finance Committee, which will play a major role in determining how to distribute the valuable emissions "allocations" that would be created by the climate bill’s cap-and-trade system.

One percent of those "allocations" were set aside for clean transport in the House climate bill. Although few on the Hill currently expect the Senate to reach the 10-percent mark set by "CLEAN TEA," the more sponsors the bill attracts, the better chance its chief sponsors — Sens. Tom Carper (D-DE) and Arlen Specter (D-PA) have of amending the climate bill to give more to transit.
