Now Rep. John Dingell (D-MI) is now reviving that effort. Dingell chairs the Energy and Commerce Committee in the House, a body that is about to release a report on roles of different levels of government in regulating greenhouse gases. Dingell wants federal rules to establish a limit on CO 2 emissions. The report states that allowing a mish-mash of different rules would be too hard on the states' economies that rely on the auto industry. The Bush administration turned down a waiver request that would have allowed California to enforce their own rules and California is now suing the EPA to overturn the decision.
