Cap-and-trade legislation collapsed on Capitol Hill last year, but EPA is acting under its existing Clean Air Act powers to begin phasing in rules to slow emissions from sources like power plants and refineries. EPA officials say they are using a moderate approach to stem emissions, and EPA Administrator Lisa Jackson has accused opponents of Clean Air Act rules of peddling in inaccurate "doomsday" rhetoric.
Inhofe is the top Republican on the Senate Environment and Public Works Committee, and Capitol Hill’s leading climate skeptic.
Inhofe is also a co-sponsor of Sen.
