On February 23, 2026, the U.S. Supreme Court granted certiorari in Suncor Energy Inc. v. County Commissioners of Boulder County—a decision that could determine the fate of dozens of climate lawsuits against fossil fuel companies nationwide .
For the first time, the Court will consider whether federal law bars state-level climate tort claims, potentially shielding oil giants from billions in damages or validating a new frontier of climate accountability litigation .
The Stakes: A Battle Over "Lawfare"
The case pits Boulder County and the City of Boulder against ExxonMobil and Suncor Energy, accused of knowingly contributing to climate change while concealing the dangers of their products. The plaintiffs seek damages to cover mounting local costs—wildfires, flooding, extreme weather—that they argue were exacerbated by decades of industry deception .
But critics like Russell Cook, a veteran climate blogger who has tracked these cases since 2017, see something more sinister: a coordinated "lawfare" campaign built on fraudulent accusations.
"The core accusation elements within essentially all of them... are all completely without merit."
Cook fired off a frustrated email to the energy companies' lead counsel, Kannon Shanmugam, asking why defendants haven't moved to dismiss these cases for failing to present a prima facie case of industry disinformation
The "ExxonKnew" Blueprint Under Scrutiny
Cook's critique targets the evidentiary foundation repeated across climate lawsuits:
Accusation Cook's Counter
"Reposition global warming" memo Never implemented anywhere
"Victory will be achieved" memo Never implemented anywhere
Old newspaper advertorials as proof Two were never published; one was cropped to hide non-disinformation text
Dr. Willie Soon took Exxon bribes "So false they may stray into epic defamation territory"
Cook argues these lawsuits should be referred to the Department of Justice for fraud investigation rather than fought on "esoteric jurisdiction technicalities" [Document].
Why SCOTUS Matters Now
The Supreme Court won't just decide if Boulder can sue—it could determine if any local government can hold fossil fuel companies accountable under state law
.
The Core Questions:
1. Does federal law preempt state climate tort claims? The companies argue interstate emissions are a national issue, not a local one .
2. Does the Court even have jurisdiction? The justices added this question themselves, suggesting internal disagreement about intervening so early .
The Trump Factor:
The Trump administration broke with precedent to unsolicitedly urge the Court to take the case and shut down climate litigation—part of a broader effort to protect American energy from "state overreach" .
Justice Samuel Alito, who recused himself from similar cases due to oil stock holdings, notably participated this time—raising ethics questions .

What Happens Next
Arguments are scheduled for Fall 2026, with a decision expected by July 2027 .
• If the Court sides with Boulder: Dozens of similar cases proceed to trial, potentially unleashing billions in liability and forcing discovery of industry documents.
• If the Court sides with Suncor/Exxon: The "ExxonKnew" litigation strategy collapses, and states' "climate Superfund" laws face new legal threats .
The Equalizer Analogy
Cook frames himself as the real "good guy" in this drama—a threat to an agenda built on "lies and defamation and actual disinformation." The activists, he suggests, are the villains posing as heroes, using the courts to punish dissent [Document].
Whether the Supreme Court sees it that way will determine not just Boulder's case, but the future of climate accountability in America.
