Potential Greenhouse Gas Regulation Under the Clean Air
Act
Two years ago, the Supreme Court of the United States, in
Massachusetts v. Environmental Protection Agency (2007),
determined that the Environmental Protection Agency (EPA) has the
statutory authority to determine whether carbon dioxide and other
greenhouse gases from new motor vehicles, as air pollutants,
endanger public health or welfare under the Clean Air Act, finding
that the EPA "must ground its reasons for action or inaction .
. ." EPA Administrator Lisa Jackson told the Wall Street
Journal last week that the EPA could make a determination on
the endangerment issue as early as April 2, 2009, the second
anniversary of the Massachusetts decision.
