The Environmental Protection Agency is proposing to register six greenhouse gases (GHG) as air pollutants that endanger public health, and although the proposal currently governs only motor vehicle emissions, it is very likely it will be extended to all transportation emissions.
The U.S. Supreme Court last April ordered the EPA to do a scientific review of the role GHGs play in climate change. EPA recently proposed to add regulation of GHGs under the Clean Air Act. "This finding confirms that greenhouse gas pollution is a serious problem now and for future generations," EPA administrator Lisa Jackson says. "The pollution problem has a solution--one that will create millions of green jobs."
The proposed endangerment addresses six gases: carbon dioxide, methane, nitrous dioxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
