The Supreme Court has agreed to hear a case brought by local governments against Exxon Mobil and other oil companies over their alleged role in contributing to climate change. The cities and counties argue that the oil companies should be held financially responsible for the impacts of climate change on their communities.

Why it matters

This case could set an important legal precedent on whether municipalities can sue fossil fuel companies for climate change-related damages. It's part of a growing trend of local governments taking legal action to hold major emitters accountable for the costs of adapting to a changing climate.

The details

Several cities and counties, including Boulder, Colorado, have filed lawsuits against Exxon Mobil and other major oil companies. They allege that the companies knew about the risks of climate change for decades but engaged in misinformation campaigns to downplay those risks. The local governments are seeking financial compensation to help cover the costs of dealing with climate change impacts like sea level rise, droughts, and extreme weather.

  • The Supreme Court agreed to take up the case in February 2026.
