The Supreme Court will hear Suncor Energy, Inc. v. County Commissioners of Boulder County on the first day of the October 2026 Term. The case asks whether lawsuits filed under state law against energy companies for their role in causing climate change are preempted, or superseded, by federal law.
The source describes the preemption doctrine in this area as "very confused," underscoring the legal uncertainty surrounding climate-related litigation. The Court's decision will determine whether state-law claims against energy companies can proceed or are blocked by federal law.
