Supreme Court Weighs Jurisdiction in Colorado Climate Tort Case
By Drooid · · How we work
Core Event
The Court’s new term opened with oral arguments in *Suncor v. Boulder*, a Colorado lawsuit that seeks to allow state-law tort claims against oil companies for climate-change harms that occur outside the state. The justices must decide whether the Supreme Court has jurisdiction while the case is pending before the Colorado Supreme Court, and whether state tort law can be used for such claims.
Procedural Context and Stakes
If the high court declines to resolve the federalism question, the Colorado Supreme Court’s decision permitting the Boulder claims will stand, leaving the broader issue of nationwide climate-damage lawsuits unresolved. Plaintiffs allege that ExxonMobil and Suncor concealed climate risks for decades, citing a 1977 internal memo warning of fossil-fuel contributions to rising CO2. Communities estimate potential taxpayer adaptation costs exceeding $100 million for wildfire, drought and infrastructure damage.
Supporters argue the litigation could “bankrupt” oil firms and raise consumer prices, effectively creating a de-facto carbon tax. State attorneys general—including Alabama’s Steve Marshall and Utah’s Derek Brown—contend the case threatens to shift energy-policy decisions from Congress to the courts.
Official Statements & Responses
Justice Ketanji Brown Jackson called the case “premature,” noting the need for a complete factual record before exercising jurisdiction. Justice Sonia Sotomayor suggested certifying the question to the Colorado Supreme Court. Chief Justice John Roberts asked Boulder attorney Kevin Russell about the potential for a cascade of similar lawsuits, while Justice Clarence Thomas was briefed on the limits of the Boulder theory.
Criticism & Opposition
Conservative analysts view the liberal justices’ focus on jurisdiction as an “off-ramp.” Carrie Severino, president of JCN, said the justices’ emphasis indicates a lack of confidence in securing a favorable vote. Hans von Spakovsky of Advancing American Freedom framed the approach as an attempt to avoid being outvoted on whether the Clean Air Act preempts state claims.
Alabama Attorney General Steve Marshall argued the lawsuits aim to impose a nationwide carbon tax that would hurt producers, “including my cattlemen in Alabama,” and ultimately bankrupt the industry. Utah Attorney General Derek Brown warned the case seeks to regulate activities far beyond Colorado, asserting that such policy decisions belong to Congress.

- “The fact that they kept going back to trying to create a jurisdictional problem tells me they don't feel confident that they have the votes in this space,” — Carrie Severino, JCN
- “If we're unsure of your characterization, because there's certainly a number of amici brief who disagree with that characterization, shouldn't we be certifying this question to the Colorado court instead of us deciding it?” — Sonia Sotomayor
