The U.S. Supreme Court began its new term by hearing arguments in a significant climate change case. The central question is whether a lawsuit filed by Boulder, Colorado, and its county against energy companies Suncor Energy and ExxonMobil can proceed in state court. Boulder filed the suit in 2018, alleging that the companies' production of fossil fuels contributed to climate change and that they knowingly misled the public about its dangers. The plaintiffs seek to hold the companies responsible for financial costs associated with climate-related hazards such as extreme precipitation, wildfires, and drought. A report from the Colorado Fiscal Institute suggests climate change could cost Colorado up to $37 billion between 2025 and 2050. The energy companies argue that the case involves national energy policy and should be heard in federal court, not state court. They contend that allowing approximately 90,000 municipalities to pursue such claims could lead to them setting national and international energy policy through jury awards. Justice Samuel Alito recused himself from the case. ## Disagreement on case progression Lawyers for the energy companies, including Kannon Shanmugam, argued that the case should be heard in federal court due to the national implications of energy policy and the potential for widespread litigation. They stated that allowing Boulder's claims to proceed would enable numerous municipalities to influence energy policy. Conversely, Kevin Russell, representing Boulder, argued that states have always had the power to provide legal remedies for injuries occurring within their borders, even if the conduct originated elsewhere. He drew parallels to cases involving defamation or computer viruses originating in other states. ## What the coverage left out None of the left-rated digests mention the Colorado Fiscal Institute's cost estimate for climate change impacts in Colorado. The right-rated digest does not mention the specific cost estimate or the arguments made by Boulder's legal representatives about states' historical power to provide tort remedies. ## Who covered it Shares of the 6 covering outlets with a published leaning rating: - Left: 67% (4) - Centre: 16% (1) - Right: 17% (1) 0 of 6 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-10-05T19:00:30.022420+00:00. **Coverage watch:** developing. Checked 1 time; 0 checks found a material change. Most recently checked 2026-10-05T19:15:30.229Z. ## How the sides framed it ### Left - Left-rated reports highlighted Boulder's argument that energy companies should be held responsible for climate change harms. Houston Public Media included personal accounts from residents affected by wildfires, such as Daryl McCool and Taylor Korn, to illustrate the human cost of climate change. These reports also featured legal experts like Corey Riday-White of the Center for Climate Integrity, who argued that corporations should be held to the same standards as individuals and assist in cleaning up harm they cause. The Seattle Times and Durango Herald digests also focused on the core issue of local governments suing energy companies for climate change costs. ### Centre - The centre-rated report from Eos focused on the legal arguments presented before the Supreme Court. It detailed the arguments from both the energy companies' lawyers, such as Kannon Shanmugam, and Boulder's legal representatives, like Kevin Russell. The report noted the potential for wide-reaching consequences for fossil fuel companies and state and local governments, and mentioned Justice Samuel Alito's recusal. It also discussed the justices' inquiries into whether the case was brought prematurely and the differing potential leanings of the court's liberal and conservative wings. ### Right - The right-rated digest from the Boston Herald stated that key justices expressed skepticism about the potential flood of litigation if the case from Boulder, Colorado, proceeds. It focused on the Supreme Court weighing whether local governments can sue oil and gas companies for climate change costs. **Provisional coverage gap:** right. The watch is not closed, so this is not yet a settled blindspot finding. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - high: 4 - veryHigh: 2 ## Verification scope This page compares coverage and scores the source reporting.
