Environmental -- 2005



Massachusetts v. EPA   (D.C. Circuit)

EPA upheld in not regulating greenhouse gases as a pollutant

These cases were filed in 2003 by 12 states and various environmental and other organizations to force the Environmental Protection Agency to regulate greenhouse gases (carbon dioxide, methane, nitrous oxide and hydrofluorocarbons) from new motor vehicles as pollutants. The EPA and 10 other states opposed the suits, and the CO2 Litigation Group, of which the NAM is a member, intervened. On 7/15/05, the D.C. Circuit issued a splintered decision allowing the EPA to continue to decline to regulate greenhouse gases. Judge Randolph ruled that the EPA had discretion and a scientific justification not to regulate greenhouse gases, and, although Judge Sentelle refused to reach this issue, he ruled that the petitioners did not have standing to bring the case. Thus, the EPA’s decision stands. Judge Tatel dissented, arguing that the EPA does have the authority and has failed to give an adequate explanation for not regulating greenhouse gases. Whether the EPA is mandated by statute to regulate greenhouse gases is unresolved. It has declined to do so at this point. The NAM does not believe the EPA has this authority, nor is there sufficient evidence that emissions of greenhouse gases from domestic automobiles endanger public health or welfare.
