Supreme Court Just Erased a 745 Million Dollar Verdict Against Chevron and Climate Lawyers Are Furious

A Louisiana jury handed climate activists a $745 million jackpot last April – and they spent a year celebrating.

Now the Supreme Court just put that verdict in serious jeopardy.

What the justices said in the process has the entire climate litigation industry scrambling to find a new playbook.

Chevron v. Plaquemines Parish: How Climate Lawyers Tried to Rig the Game

This wasn't an environmental case. It was a venue-shopping operation.

Climate lawyers have spent years perfecting the strategy: file lawsuits against energy companies in state courts, where local juries are easier to inflame and judges are more sympathetic to billion-dollar environmental damage claims.

Plaquemines Parish, Louisiana filed its lawsuit against Chevron back in 2013 – one of roughly 40 similar suits filed by coastal parishes against oil and gas companies.

The theory was straightforward. Blame decades of Louisiana coastal erosion on Chevron's drilling operations, find a receptive state court jury, and collect.

It worked in April 2025, when a Louisiana state jury ordered Chevron to pay $745 million to restore coastal wetlands.

Chevron appealed to the Supreme Court on a single argument: the company's Louisiana oil production during World War II was performed under federal contract – producing aviation fuel for American fighter planes – and any lawsuit challenging that work belongs in federal court, not a plaintiff-friendly state venue.

The Supreme Court agreed in an 8-0 ruling, with Justice Clarence Thomas writing for the majority.

"Chevron's wartime crude-oil production was closely connected to its wartime avgas refining," Thomas wrote.

The ruling doesn't hand Chevron an outright win on the merits. It moves the case into federal court – where the $745 million verdict is vacated and the entire dispute starts over before a judge far less likely to side with the climate lobby.

The Supreme Court Just Handed Big Oil a Way Out of 40 Climate Lawsuits

That $745 million number is just the beginning of what's at stake.

Forty similar lawsuits are pending against oil and gas companies across Louisiana's coastal parishes – every one of them filed in state court, every one of them following the same playbook.

This ruling moves them all into federal jurisdiction and potentially guts every single one.

The Judicial Crisis Network's Carrie Severino put it plainly: "Yet another scheme by the climate lobby to weaponize the courts and forum-shop has been thwarted."

Tommy Faucheux, president of the Louisiana Mid-Continent Oil and Gas Association, called it what it was from the beginning.

"These misguided lawsuits never belonged in state court," Faucheux said. "Hopefully, the state will take this opportunity to bring these suits to an end so we can collectively focus on the energy opportunities that lie ahead for Louisiana."

The Trump administration had backed Chevron's position before the court.

When the White House and the Supreme Court align, the climate litigation machine doesn't just lose a case – it loses the strategy.

Clarence Thomas Just Shut Down the Climate Lobby's Billion Dollar Lawsuit Strategy

Here's what the environmentalists don't want you to understand.

This lawsuit was never really about Louisiana's coastline.

It was about establishing a template – the same one used against Big Tobacco in the 1990s – to bleed American energy companies dry through endless state court litigation, stacking up verdicts until companies settle for billions rather than keep fighting.

The Supreme Court's 8-0 ruling didn't just stop one lawsuit. It shut down that entire approach every time a company can show federal ties to the challenged work.

And almost every major American energy company has federal ties somewhere in its history.

Chevron fueled American fighter planes during World War II.

For that, Louisiana's climate lawyers wanted $745 million.

Justice Clarence Thomas – writing for a unanimous court – said no.
