History

Historical Context

In 2007 the Supreme Court’s 5–4 ruling in Massachusetts v. EPA held that greenhouse gases are air pollutants, forcing the EPA to regulate emissions under the Clean Air Act. That precedent underlies today’s term, where the Court hears Exxon Mobil and Suncor Energy’s appeal of Boulder County climate lawsuits, a case that could protect fossil-fuel firms from billions of dollars in liability.
