The Environmental Protection Agency ruled yesterday it does not have the authority to regulate carbon dioxide and greenhouse gas emissions from cars. The decision is seen as a major victory for the automobile industry. Three environmental groups including Greenpeace and Sierra Club petitioned the EPA to regulate the emissions in order to control global warming. But the EPA claimed Congress did not give it the power to declare carbon dioxide from autos as a pollutant under the Clean Air Act. An attorney from the Sierra Club said “The Bush administration is again ducking its legal and moral responsibility to address global warming. But instead of just admitting that it isn’t doing anything about global warming, now the Bush administration is saying it’s not their job.”
