illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on CNN or enjoy below:

🗞️ Driving the news: The US Supreme Court heard arguments in a major climate lawsuit brought by Boulder against ExxonMobil and Suncor, seeking to hold the companies financially responsible for climate-related harms
• The justices appeared divided over whether state and local courts can hear such claims when climate and carbon regulation largely crosses state and national borders

🔭 The context: Conservative justices including Brett Kavanaugh and John Roberts questioned whether allowing Boulder’s case could open the door to similar lawsuits nationwide
• Elena Kagan, meanwhile, challenged the oil companies’ argument that federal law automatically prevents state claims, asking: “Where’s the text for that?”
• The case also echoes 1990s tobacco litigation, where states pursued companies over alleged public deception and health harms

🌍 Why it matters for the planet: A ruling allowing the case to proceed could preserve a legal pathway for communities seeking compensation for climate-related damages from fossil-fuel companies
• A broader ruling against such suits could constrain one avenue for climate accountability and potentially shift more responsibility toward federal policymaking

⏭️ What’s next: The court is expected to rule next year
• Justice Samuel Alito’s recusal, because of his holdings in energy companies, leaves open the possibility of a 4–4 split, which would leave the Colorado ruling in place without establishing a nationwide precedent.

💬 One quote: “We’re on a wall of precedent that says state tort law does not apply,” Justice Brett Kavanaugh said during the arguments

📈 One stat: 40 similar climate lawsuits have been brought by cities, states, tribes and other local jurisdictions, according to reporting cited in the article
