Barbara Boxer

Senate environment committee chairman Barbara Boxer (D-CA) and fellow lawmakers yesterday pressed the Obama administration to take a more active role in ending the current political stalemate over federal transportation funding, but the sense of urgency they sought emerged only intermittently during an 80-minute session on infrastructure.

Republicans on the Senate environment committee made good on their vow to boycott this morning's first meeting on climate change legislation, leaving Democrats to poke holes in the GOP's insistence on a new Environmental Protection Agency (EPA) analysis of the bill.

The Senate environment committee released new details of its climate change legislation over the weekend, including the share of "emissions allowances" -- the revenue generated by regulating carbon in a cap-and-trade system -- that the bill would reserve for various sectors of the American economy.

The Senate is leaning towards abandoning the Obama administration's push for an 18-month delay of the next long-term transportation bill and now plans to pursue a six-month extension of existing federal infrastructure law, according to a report from CQ this afternoon:

Flanked by fellow Democrats, members of the military, and a crowd hoisting signs with buzzwords like "clean energy" and "green jobs," Sens. Barbara Boxer (D-CA) and John Kerry (D-MA) today released the first draft of their legislation to curb U.S. emissions and combat climate change.

The transportation spending bill passed by the Senate this week includes $50 million in rail safety grants sought in June by environment committee chairman Barbara Boxer (D-CA) -- but the bill may not become law for months, and today Boxer told California's Metrolink commuter rail that interim safety protections would have to stay in place.

Streetsblog Capitol Hill reported this week that the Obama administration -- which often talks about reducing transportation-based emissions -- is staying mum on a bill that would devote a guaranteed share of revenues from carbon regulation to transit, bike paths, and other green modes of transport.

This was supposed to be a big week for action on climate change in the Senate -- but it's ending with Republicans rubbing their hands in glee as the Environment and Public Works Committee delays its unveiling of legislation on carbon emissions.

Green transportation advocates are pressing Congress to refuse any new spending that's not tied to reform of the existing system -- a call that influential senators in both parties ruled out today.
