On Monday, February 24, the United States Supreme Court watched the Environmental Protection Agency (“EPA”), industry groups and sympathetic states take the ring over what the challengers call a “brazen power grab” by the Obama Administration and its environmental regulators, aimed at limited carbon emissions from new stationary sources such as power plants and factories.
This is not the first time the same parties have squared off over greenhouse gas (“GHG”) regulation. In 2008, the Obama Administration initiated rules governing mobile sources, requiring new motor vehicles to demonstrate better fuel efficiency and, thus, reduce carbon emissions. The High Court effectively upheld those rules by refusing to hear the challenges against them. The Administration this week announced plans to expand mobile source regulation by enacting new limits on carbon emissions for trucks and buses. EPA has hit a brick wall, however, with its expansion of regulation to stationary sources, concerning which the High Court will now be hearing oral argument on six different appeals. The upcoming legal battle, like so many others over environmental regulation, is fraught with political overtones, as well as a variety of legal issues.
