Groups want national limit on greenhouse gases
The Center for Biological Diversity and 350.org want EPA to use the Clean Air Act to dramatically scale back greenhouse gas emissions.
“The Clean Air Act provides the tools necessary for the U.S. to commit to the deep and rapid greenhouse emissions reductions – on the order of 45 percent or more below 1990 levels by 2020 – needed to avert the worst impacts of climate change,” a petition the groups sent EPA states.

Some context: the House climate bill calls for a 17 percent emissions cut by 2020 from 2005 levels.
The petition has its critics. Jeff Holmstead, former EPA administrator for air and current head of Bracewell & Giuliani's Environmental Strategies Group, which represents utilities, refiners and other energy companies, called it "more of a political statement than a serious legal effort."
