The Colorado Supreme Court has made a landmark decision allowing Boulder County to pursue its climate change lawsuit against Exxon Mobil and Suncor Energy, rejecting the companies' attempts to have the case dismissed.
In a significant legal development, the Colorado Supreme Court ruled on Monday that the city of Boulder can proceed with its lawsuit against oil companies Exxon Mobil and Suncor Energy. The lawsuit seeks compensation for climate change damages allegedly caused by the companies’ fossil fuel products.
The decision marks another instance where state courts have allowed climate-related lawsuits to move forward despite numerous attempts by energy companies to have these cases dismissed or transferred to federal courts.
Legal Battle Over Climate Accountability
Boulder, along with Boulder County and San Miguel County, initially filed the lawsuit in 2018, claiming that Exxon and Suncor Energy knowingly produced and marketed fossil fuel products that contributed to climate change. The plaintiffs are seeking compensation for the costs associated with responding to climate-related disasters and implementing measures to mitigate future damage.
The Colorado Supreme Court’s decision upholds a lower court ruling that rejected the companies’ argument that the case should be dismissed because climate regulation falls under federal, not state, jurisdiction.
“We conclude that the federal Clean Air Act does not completely preempt the Counties’ state law claims,” the Colorado Supreme Court stated in its ruling.
Broader Implications for Climate Litigation
This ruling is part of a broader trend where similar climate lawsuits are proceeding in state courts across the United States. Last month, Delaware’s highest court allowed the state to continue with its climate change lawsuit against major oil companies, including BP, Chevron, and Exxon Mobil.
Environmental advocates view the Colorado decision as a significant step toward holding fossil fuel companies accountable for their role in climate change. Critics, however, argue that addressing climate change requires comprehensive policy solutions rather than piecemeal litigation.
The oil companies involved have consistently maintained that these lawsuits lack merit and that climate policy should be addressed through legislation rather than litigation.
Industry Response and Next Steps
Representatives from Exxon Mobil expressed disappointment with the ruling, stating that the company will review its legal options moving forward. Suncor Energy has not yet issued a public response to the decision.
The case will now return to the district court for further proceedings, where the plaintiffs will need to substantiate their claims about the companies’ role in climate change and the specific damages incurred by the Colorado communities.
Legal experts note that this case could potentially set precedent for how similar climate litigation proceeds nationwide, particularly regarding whether fossil fuel companies can be held financially liable for climate-related damages under state common law.
As climate change continues to impact communities across the United States through increased wildfires, flooding, and extreme weather events, more local governments are considering similar legal action against major carbon emitters.
