In recent years, the U.S. Supreme Court has joined the other branches of government in the debate over national energy policies and environmental standards. In 2007, the Court famously granted cert in a case concerning greenhouse gas regulations when it agreed to hear Massachusetts v. EPA. The case involved a challenge by several states and environmental organizations to the decision by the Bush Administration and the EPA to not regulate carbon dioxide under the Clean Air Act. With potential ramifications for industry, including the entire electric power industry and its associated employees, a coalition of 12 major manufacturing and energy labor unions turned to the PRG team to undertake the drafting and filing of an amicus brief with the Court. PRG also assisted with the rollout and strategic communications associated with the brief and the positions it espoused.
