AZ Attn Gen Challenges EPA

Attorney General Terry Goddard today filed a friend of the court brief with the U.S. Supreme Court supporting arguments that the Environmental Protection Agency has the authority to regulate climate change pollutants from motor vehicle exhaust.

The case, Massachusetts v. EPA, stems from a 2003 EPA decision to reject a request from several states asking the federal agency to regulate pollutants that contribute to climate change.  EPA concluded that it did not have authority under the Clean Air Act to regulate these pollutants. They are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and hydro fluorocarbons (HFCs).
