🗞️ Driving the news: The US Supreme Court has agreed to hear an appeal from ExxonMobil and Suncor Energy challenging whether state and local climate lawsuits can proceed in state courts — a decision that could reshape dozens of similar cases nationwide.

🔭 The context: State courts vs. federal courts
• Boulder, Colorado sued ExxonMobil and Suncor for climate-related damages, arguing their fossil fuel production worsened local impacts such as wildfires, floods, and heatwaves
• The Colorado Supreme Court ruled in May 2025 that the case could move forward in state court
• Oil companies argue such cases belong in federal court, where legal precedent is generally seen as more favorable to them
• More than two dozen Republican-led states and the Trump administration supported the companies’ appeal

🌍 Why it matters for people and the planet: Who pays for climate damage?
• Cities and states nationwide are seeking compensation for climate adaptation costs
• If the Supreme Court limits state-court jurisdiction, many lawsuits could be dismissed or significantly weakened
• The case intersects with broader efforts by fossil fuel interests to seek congressional immunity from climate litigation
• Concerns have resurfaced about Justice Samuel Alito’s participation due to fossil fuel holdings valued between $60,000 and $245,000

⏭️ What’s next: A ruling with national ripple effects
• Oral arguments have not yet been scheduled
• The decision could affect dozens of pending climate lawsuits across the US
• The Court is also weighing a separate $745 million Louisiana climate verdict against Chevron
• A ruling narrowing state authority could shift the landscape of climate liability law for years

📈 One stat: More than 26 states filed briefs supporting fossil fuel companies in their effort to move climate cases out of state courts
