WASHINGTON, D.C. – America’s Supreme Court will start its new term with one of the most consequential environmental cases in years. On Monday, October 5, the justices will hear arguments in Suncor Energy (U.S.A.) Inc. v. County Commissioners of Boulder County. The ruling could decide whether oil companies can be forced to pay for local damage linked to climate change.
It is the first case of the fall 2026 term, and arguments are scheduled to begin at 10 a.m. Eastern (8 a.m. Mountain Time).

What the Case Is About
Boulder County and the City of Boulder first sued Suncor entities and ExxonMobil in April 2018. The local governments argue the oil companies misled consumers about the harms of burning fossil fuels and should share the cost of adapting to worsening climate disasters such as floods and wildfires.
ExxonMobil is the country’s largest oil company, and Suncor Energy runs two refineries in Colorado.
The U.S. Supreme Court is not deciding whether climate change is real or whether oil companies caused it. As SCOTUSblog noted, that question is not before the Court. Instead, the justices will decide who gets to hear these claims and under which law.
The Two Legal Questions
The Court is weighing two questions: whether federal law preempts Boulder’s claims, and whether it is too early to hear the case at all.
1. Federal preemption. The companies say climate claims tied to emissions across the country and the world belong under federal law, not state law. They argue the Clean Air Act and the Constitution prevent Boulder’s claims from moving forward under state law.
2. Jurisdiction. Boulder also challenges the Supreme Court’s authority to hear the case, arguing there is no final state-court judgment to review. If the justices agree, they could dismiss the appeal without ever reaching the preemption question.
How the Case Got Here
The path to the Supreme Court took eight years. After the federal district court sent the case back to Colorado state court, the U.S. The Supreme Court declined to review it on April 24, 2023.
The case then returned to Colorado. A 5–2 majority of the Colorado Supreme Court rejected Suncor’s preemption arguments and sent the case back to the trial court. Suncor and ExxonMobil petitioned the U.S. Supreme Court on August 8, 2025, and the Court agreed to hear it on February 23, 2026.
That reversal is notable. Between 2023 and 2025, the Court turned away oil company petitions in nine cases raising essentially the same issue.
The federal government will also have a voice at the podium. The Court granted the Solicitor General’s motion to take part in oral argument as an amicus and divide argument time.
Alito Steps Aside: Why It Matters
The biggest twist in Supreme Court news today, in October, came just one week before arguments. Justice Samuel Alito recused himself on September 28, leaving eight justices to decide the dispute.
The Court gave no explanation, and its rules leave recusal decisions to individual justices without requiring them to explain. However, CBS News reported the likely reason is his stock holdings in oil and gas companies, based on his 2025 financial disclosure.
Alito doesn’t own shares in ExxonMobil or Suncor, but he does own stock in companies facing lawsuits that will turn directly on this decision.
An eight-justice bench creates a real chance of a tie. Yale Law professor Harold Hongju Koh noted the possibility of a 4–4 split, which would leave the 2025 Colorado Supreme Court ruling in place. That outcome would let Boulder’s case proceed but would set no national precedent.
Dozens of Lawsuits Are Waiting
This case reaches far beyond Colorado. More than two dozen states, cities, and local governments have filed similar lawsuits seeking compensation for climate costs, according to Reuters.
State judges have paused 11 such cases in recent months while waiting for the Suncor ruling. These include suits brought by California, New Jersey, Delaware, Hoboken, and eight California cities and counties.
Exxon and Suncor told the Court they face lawsuits seeking billions of dollars in damages and urged review to stop dozens of climate cases from moving ahead in state courts.
