US Supreme Court Considers Oil Companies’ Request to Dismiss Climate Change Lawsuits
The U.S. Supreme Court has agreed to hear a bid by ExxonMobil and Suncor Energy to dismiss a lawsuit initiated by officials in Boulder, Colorado. This case seeks to hold the oil companies accountable for their role in exacerbating climate change, and its outcome could influence numerous similar lawsuits across the nation.
On Monday, the justices accepted an appeal from the companies regarding a lower court’s ruling that allowed the litigation to proceed. The lawsuit alleges violations of state law and seeks unspecified monetary damages for costs incurred by Boulder in its efforts to mitigate climate change impacts.
The appeal has garnered support from the Trump administration, which has backed the oil companies in their legal battle.
This litigation is part of a broader movement among various U.S. jurisdictions aiming to seek damages from companies involved in the extraction, production, distribution, or sale of fossil fuels. Plaintiffs argue that these companies should be held responsible for the harms associated with climate change, which they attribute to the companies’ actions.
Burning fossil fuels releases greenhouse gases, such as carbon dioxide, into the atmosphere. This process traps more of the sun’s heat, leading to a gradual increase in the average global temperature.
“As our filings make clear, climate policy shouldn’t be set through fragmented state‑court actions, and we look forward to making that case before the court,” stated an Exxon spokesperson on Monday.
In their 2018 lawsuit, Boulder officials accused Exxon and Suncor of misleading the public about the impact of their products on climate change while profiting from unchecked fossil fuel sales. Both companies have denied any wrongdoing.
The plaintiffs argue that the oil companies should bear the costs associated with past and future measures taken by city and county governments to mitigate climate change effects. These costs include infrastructure repairs, environmental damage, emergency management, and public health impacts.
“Local communities are living with the mounting costs of climate change,” remarked Aaron Brockett, the mayor of Boulder, following the Supreme Court’s decision to take up the case. “The Supreme Court should affirm Colorado’s right to hold these companies accountable for the harm they have caused in Colorado.”
The companies have urged lower courts to dismiss the case, contending that Boulder’s lawsuit would unlawfully interfere with federal regulations on greenhouse gas emissions under the Clean Air Act.
In May 2025, the Colorado Supreme Court rejected their request, leading to the appeal to the U.S. Supreme Court.
For years, oil companies have sought to evade the increasing number of climate-related lawsuits, but they have met with limited success. Nearly 60 state and local governments have filed similar lawsuits, seeking billions in damages, with more cases continuing to emerge.
The Trump administration has taken various actions to support the oil companies, including launching preemptive lawsuits to prevent states like Hawaii and Michigan from filing climate-related lawsuits that could threaten domestic energy production.
Previously, the Supreme Court dismissed a similar attempt by Sunoco and other oil companies to quash a climate-related lawsuit from Honolulu, which had been allowed to proceed by Hawaii’s top court. This lawsuit seeks to hold the companies accountable for their alleged contributions to extreme weather events and rising sea levels affecting the Honolulu coastline, leading to flooding, erosion, and beach loss.
