The Supreme Court will hear arguments on Monday in a case that could determine the fate of state-court lawsuits seeking climate damages from oil companies. The ruling may impact billions of dollars in potential liability for the industry in dozens of active cases brought by state and local governments.
The specific litigation involves claims filed by the city and county of Boulder against Exxon and Suncor in 2018. While the Supreme Court's decision will focus on this dispute, the outcome carries broader implications for similar cases active in California, Connecticut, New York, Massachusetts, and other jurisdictions. These suits generally accuse major oil firms of concealing risks or making deceptive statements regarding their products' climate impacts.
The central legal question is whether federal law blocks damage claims under state laws for the effects of interstate and global emissions. Industry groups and allies argue that this wave of litigation threatens oil companies' ability to operate, viewing the courts as a critical battleground in the climate debate. Conversely, climate advocates maintain that these cases fall within traditional state powers.
A procedural wrinkle complicates the proceedings. The Court is also considering whether it has jurisdiction at this stage, a question that turns on whether a Colorado Supreme Court decision allowing Boulder's case to proceed in state court is reviewable now. Consequently, the justices may not reach the federal preemption question.
Arguments from the United States and industry briefs assert that addressing interstate and global topics through these state claims is preempted by federal law and the Constitution. However, observers are watching to see if the White House's attempt to repeal key Clean Air Act authority over greenhouse gases influences these preemption claims. Litigants against oil companies contend their cases remain within longstanding state boundaries.
Justice Samuel Alito has recused himself from the case. Environmental law scholar Jonathan Adler noted that Alito's absence is likely unfavorable to the petitioners, as he is considered one of the more preemption-friendly justices on the bench.
The decision could have ripple effects beyond immediate damages. A ruling in favor of oil companies might jeopardize separate state climate policies, including "climate superfund" laws in New York and Vermont that assess damages against fossil fuel companies to fund climate adaptation. Both states' laws are currently tied up in court, while several other states are considering similar legislation.
