## Exxon and Suncor seek Supreme Court block
Texas-based Exxon Mobil and Suncor Energy will ask the U.S. Supreme Court on Monday to block a Colorado climate-damages lawsuit, in a case that could shape nationwide claims against energy companies.
## Boulder's climate claims
Boulder County and the city of Boulder allege the companies knowingly contributed to climate change by producing and selling fossil fuels while misleading the public about risks.
## Boulder's legal claims
The local governments seek monetary damages for harm to property and costs of protecting residents' health and safety, without halting oil and gas operations or emissions limits.
## Colorado Supreme Court ruling
The Colorado Supreme Court rejected the companies' federal preemption arguments in May 2025, allowing the case to continue without establishing liability or damages.
## Federal preemption debate
The central question is whether federal law bars state-law claims seeking compensation for injuries allegedly caused by interstate and international greenhouse-gas emissions affecting the global climate.
## Trump administration support
The Trump administration supports the companies, urging reversal of Boulder's claims as they intrude on federal authority and conflict with the Clean Air Act.
## Jurisdictional dispute
The justices will address whether the Colorado decision qualifies as a final judgment under federal law and causes sufficient injury for constitutional review.
## Key takeaway

Exxon and Suncor Energy request Supreme Court to block Colorado's climate-damages lawsuit claiming they misled the public about climate risks.
