As Exxon and BP have discovered, a company may be held liable for endangering or polluting the environment. Recently, several attorney generals have commences a law suit against the nation's five largest emitters of carbon dioxide (CO2) pollution to force reductions in their emissions of the heat-trapping gas. The U.S. Supreme Court has granted certiorari indicating that it would hear American Electric Power v. Connecticut, an appeal of the U.S. Second Circuit Court of Appeal's ruling that states and environmental groups could sue under federal public nuisance law to force electric utilities to reduce greenhouse gas emissions.
