The Administrator for the federal Environmental Protection Agency calls it "strong validation."
On Tuesday, the U.S. Court of Appeals in Washington, D.C. ruled that the EPA is "unambiguously correct" to use the Clean Air Act to regulate emissions from vehicles, power plants and industrial sites.
Through more than 50 lawsuits, industry and state officials were challenging recent steps the EPA has taken to put limits on those emissions. They were questioning whether the EPA had the authority to do so.
In a statement, Administrator Lisa Jackson said the Court’s ruling shows the EPA followed the science and the law in taking, what she calls, common sense, reasonable actions to address climate change by limiting greenhouse gas.
The Court heard arguments on the case in February. The ruling creates a clear path for the steps the EPA is taking on emissions limits.
