A House panel voted Wednesday to subpoena EPA documents related to a 2007 Supreme Court decision on global warming.

The House Select Committee on Energy Independence and Global Warming approved the subpoena by a 12-0 vote.

Panel Chairman Edward J. Markey , D-Mass., wants the EPA to provide information about its delayed response to the Supreme Court’s decision in Massachusetts v. EPA. In April 2007, the court ruled that carbon dioxide was a pollutant under the Clean Air Act and required the EPA to evaluate possible rules to control greenhouse gases.

While the court’s decision pertained to emissions from cars and trucks, an EPA decision to limit greenhouse gases could also have sweeping impact on other sectors of the economy.

The EPA had announced plans to respond to the court decision by the end of last year, but changed course after the president signed a new law raising fuel efficiency standards. EPA Administrator Stephen L. Johnson said he needed time to review the law’s new mandates on fuel economy and biofuels, both of which indirectly affect greenhouse gas emissions.

Markey and other Democrats reject the claim that the new law constitutes grounds for delay. For several months, Markey has been seeking documents including a draft proposal to regulate greenhouse gas emissions that the EPA reportedly completed last year.
