Andrew Harnik—Getty Images  by [Simmone Shah](https://time.com/author/simmone-shah/)  ## Simmone Shah Reporter Aug 11, 2026 2:41 PM UTC The [Supreme Court ](https://time.com/6193347/climate-supreme-court-decision-damage/)is set to hear oral arguments this fall in a landmark case to determine whether local and state governments can sue fossil fuel companies for climate-related disaster costs. The case, _Suncor v. Boulder_, will be heard on Oct. 5, when the court returns from summer recess. The decision—which will likely come months after the case is heard—will set a precedent for some two dozen other [climate](https://time.com/section/climate/) accountability cases that have been brought forward by states, counties, and cities. “This lawsuit is really about ensuring that corporations that have caused harm pay their fair share, rather than the burden being on the public and local governments for escalating climate impacts,” says Nikki Reisch, director of the climate and energy program at the Center for International Environmental Law. **Read more:** [_Her Mother Died in a Heat Wave. Is Big Oil Responsible?_](https://time.com/7312123/big-oil-heat-wave-lawsuit/) Fossil fuels like coal, oil, and gas are the [largest](https://www.un.org/en/climatechange/science/causes-effects-climate-change) contributor to global climate change, accounting for around 68% of global greenhouse gas emissions and nearly 90% of all carbon dioxide emissions. Major fossil fuel companies have long known—[and sometimes hidden](https://climateintegrity.org/evidence/climate-deception)—the role their products have had in fueling the climate crisis. With climate change intensifying the impact of natural disasters, states and local governments are now facing [billions of dollars](https://jayapal.house.gov/2026/08/03/jayapal-and-whitehouse-lead-90-colleagues-in-brief-supporting-the-ability-of-states-and-localities-to-hold-big-oil-and-gas-companies-accountable-for-climate-related-harms/) in climate change-driven damages—and seeking accountability. ## What is the main question in _Suncor v. Boulder_ thatthe U.S. Supreme Court must decide on? The case set to be heard by the U.S. Supreme Court will determine which government body is able to take action on these types of climate lawsuits. “The main issue is whether state courts have the power to issue money damages over climate change, or whether that's exclusively a matter of federal law that has to be decided by federal courts or by Congress or the president,” says Michael Gerrard, founder of Columbia University’s Sabin Center for Climate Change Law. In May, the Colorado Supreme Court ruled that the city ofBoulder had the legal authority to hold energy companies accountable for local damage caused by climate change and could make a case against polluters. The U.S. Supreme Court will determine whether local governments have the authority to seek damages from fossil fuel companies—but will hear the case before the accountability lawsuit has gone to trial in Boulder,which could create an opening for the federal case to be sent back to Colorado. “It is possible that the Supreme Court will rule that this case is too early…because there hasn't been a trial yet,” says Gerrard. The case comes as the Trump Administration continues to target climate action on the state and federal level. Last April, President Trump signed an [executive order](https://www.whitehouse.gov/presidential-actions/2025/04/protecting-american-energy-from-state-overreach/) to “stop the enforcement of State laws” on climate change, with a particular focus on California, New York, and Vermont. He has also struck five deals worth roughly $3.9 billion to block offshore wind projects, with the companies instead investing in fossil fuel projects. Justice Samuel Alito has also come under [fire](https://heated.world/p/sam-alito-has-an-oil-money-problem) for refusing to recuse himself from the _Suncor_ case, despite his financial investments in fossil fuel companies. (Alito isnot personally invested in either of the companies named in the lawsuit.) In a May statement to [NBC News](https://www.nbcnews.com/politics/supreme-court/justice-alito-pushes-back-calls-recuse-major-supreme-court-climate-cas-rcna345305), a court spokesperson said that “Justice Alito does not have a financial interest in any party” involved in the case, and the court’s legal counsel advised that “his recusal is not required.” Several major insurance trade groups also submitted a friend-of-the-Court brief in support of the fossil fuel company defendants. “You would think that insurance companies that are on the front lines of witnessing the scale of losses that community members and homeowners are facing would be siding with the majority of their policyholders, who have a stake in seeing the responsible parties bear the cost of climate losses,” says Reisch. “But instead, we saw them basically acting as a mouthpiece of the fossil fuel industry and sounding the alarm that cases like this will somehow make it more difficult for energy companies, and particularly fossil fuel companies, to obtain liability insurance.” ## What precedent will the U.S. Supreme Court’s decision on _Suncor v. Boulder_ set? A win for the plaintiffs could pave the way for local authorities to seek compensation from the biggest emitters. “If the plaintiffs win on the issue that it's within the power of state courts to issue money damages against the fossil fuel companies over climate change, then these two two dozen other cases that are pending will move forward, and it may be that other similar cases might be filed around the country,” says Gerrard. However, a loss in the U.S. Supreme Court could put a halt to the many other local cases seeking damages from fossil fuel companies. “If the Supreme Court were to really narrow and prevent claims like this from going forward, it could have a significant effect on whether other cases, grounded in similar arguments and on similar state law claims, could proceed as well,” says Reisch. The case’s significance cannot be understated, says Reisch. “This is the biggest climate-related case that the Supreme Court has heard, and it really goes to fundamental issues of fairness about whether or not communities can hold the companies that have been major drivers of climate change, and contributors to climate harm through the deceptive marketing and \[upstream production and sales\] of fossil fuel products, … accountable \[for their contributions to\] the mounting losses.” But a loss in court doesn’t mean the fight is over. Experts say they still expect to see cases brought against fossil fuel companies under other legal grounds, as well as cases brought in other countries. “These lawsuits are one piece of the picture of trying to hold the oil companies accountable for climate change,” says Gerrard. “It's not the only piece.” ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/article/2026/08/11/us-supreme-court-suncor-v-boulder-climate-accountability/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/article/2026/08/11/us-supreme-court-suncor-v-boulder-climate-accountability/"},"headline":"The U.S. Supreme Court Will Hear a Major Climate Change Case This Fall","datePublished":"2026-08-11T14:41:36.248Z","dateModified":"2026-08-11T14:41:40.062Z","description":"The decision could set a significant precedent for holding fossil fuel companies accountable.","url":"https://time.com/article/2026/08/11/us-supreme-court-suncor-v-boulder-climate-accountability/","keywords":["policy"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt45fa96e79215c167/6a7b2b79c99c561609894f4e/scotus-suncor.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Simmone Shah","jobTitle":"Reporter","url":"https://time.com/author/simmone-shah/"}],"articleSection":"Climate","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt45fa96e79215c167/6a7b2b79c99c561609894f4e/scotus-suncor.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"scotus-suncor.jpg","caption":"","creditText":"Andrew Harnik—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/climate/","name":"Climate"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/policy/","name":"policy"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/article/2026/08/11/us-supreme-court-suncor-v-boulder-climate-accountability/","name":"The U.S. Supreme Court Will Hear a Major Climate Change Case This Fall"}}]}] ```
