Supreme Court wrestles with energy companies' bid to block major climate-change lawsuit
Updated on: October 5, 2026 / 10:35 PM EDT / CBS News
TL;DR
- The Supreme Court heard oral arguments in Suncor Energy v. Commissioners of Boulder County, a case concerning Boulder's lawsuit against energy companies for climate change effects.
- Justice Samuel Alito recused himself from the case, potentially leading to a 4-4 deadlock, which would uphold the Colorado Supreme Court's decision allowing the lawsuit to proceed.
- The core issue is whether federal law bars Boulder's lawsuit, which alleges energy companies' conduct contributed to climate change, causing local harms.
- Justices debated whether interstate air and water pollution are matters of federal law, referencing past Supreme Court precedents and the Clean Air Act.
- Boulder argues its lawsuit, based on state law claims including deceptive marketing, is not an attempt to regulate emissions but to recover local costs.
- Energy companies and the Trump administration argue that such lawsuits exceed state authority and could lead to widespread national and international energy policy by jury.
- The Supreme Court is expected to issue a decision by the summer of 2027.
