Case Overview
Boulder County and the City of Boulder are pursuing a climate accountability lawsuit seeking to ensure fossil fuel companies pay their fair share for climate-driven harms affecting local communities.
The case centers on this question: Who should bear the rising costs of climate impacts on Colorado? Right now, families and taxpayers are paying the price for the climate impacts we are facing, but they shouldn’t shoulder the burden of these costs alone. The lawsuit is not about regulating emissions or stopping fossil fuel production, but about seeking accountability for climate-related damages.
Colorado is already experiencing more extreme heat, wildfires, drought, and poor air quality, all of which create significant public costs. Since 2018, the lawsuit against ExxonMobil and Suncor has survived repeated attempts by the companies to move or dismiss it, clearing both a district court and the Colorado Supreme Court. Now the fossil fuel companies are asking the U.S. Supreme Court to intervene. The outcome carries local and national implications for climate accountability.
