Abstract

In July 2004, eight states, the City of New York, and a number of conservation organizations filed suit against several of the nation’s largest electric power producers, alleging that the power companies’ greenhouse gas (GHG) emissions contributed to the public nuisance of global warming under federal common law. Simultaneously, several of the same states sued the U.S. Environmental Protection Agency (EPA), alleging that GHG emissions constituted “pollutants” subject to regulation under the Clean Air Act (CAA). Both cases sought to impose GHG emission controls, and both were a reaction to the federal government’s steadfast refusal to adopt such policies on its own.

Although the cases raised different legal arguments, their fates were intertwined. It was well understood that prevailing in one case would likely preclude victory in the other. Indeed, the point of parallel litigation was to make it more difficult for industry and the EPA to stave off action. The EPA had determined GHGs were not subject to regulation under the CAA. If that were so, the states argued, the CAA could not preclude common law-based claims against GHG emissions. Thus, when the states prevailed in Massachusetts v. EPA and the Supreme Court declared that GHG emissions “fit well within the Clean Air Act’s capacious definition of ‘air pollutant,’” the outcome of American Electric Power Co. v. Connecticut (AEP) was all but assured.

It just took a while for this message to be heard.
