The US Supreme Court will hear ExxonMobil and Suncor Energy’s challenge to a climate lawsuit brought by Boulder, Colorado, officials, in a case that could shape nearly 60 similar actions by state and local governments. Boulder and Boulder County accuse the companies of misleading the public about fossil fuels’ climatic effects while continuing to promote and sell them. They seek unspecified damages for climate-related infrastructure repairs, environmental damage, emergency management and public-health costs. The companies deny wrongdoing and argue that federal law, including the Clean Air Act, precludes the state-law claims. President Donald Trump’s administration supports the companies. The dispute follows earlier Supreme Court rulings that limited federal climate-liability claims and helped energy companies move some cases into federal court. A ruling for ExxonMobil and Suncor could result in many similar lawsuits being dismissed.
