The U.S. Environmental Protection Agency says it does not have the legal authority to regulate emissions of carbon dioxide and other greenhouse gases.
"The Environmental Protection Agency ruled yesterday that it lacks authority under the Clean Air Act to regulate carbon dioxide and other greenhouse gas emissions from automobiles in another major victory this week for industry...Environmentalists said the decision marked an 'abrupt about-face' by the EPA...President Bush disavowed a landmark 1997 international global warming treaty shortly after he took office, and his administration has rejected measures that would force utilities and manufacturers to meet mandatory targets for reducing carbon dioxide, a heat-trapping gas that many researchers have linked to the problem of the earth's rising temperature."
