Subnational governments across the United States are increasingly deploying state tort law to hold fossil fuel companies financially accountable for climate change adaptation costs, according to legal scholarship published by the University of Chicago Law School. The litigation wave, spanning jurisdictions from Boulder County, Colorado, to Honolulu and Puerto Rico, seeks to shift financial burdens away from taxpayers and onto energy producers whose products drove global emissions.
Climate Accountability Litigation and the Polluter-Pays Principle
According to legal scholars Alejandro E. Camacho and Robert L. Glicksman, these subnational lawsuits represent the most significant wave of climate accountability litigation in American history. The legal strategies rely heavily on the polluter-pays principle, an accepted norm of international environmental law designed to achieve the internalization of environmental costs. By ensuring that remediation expenses are borne by those who cause pollution, the principle prevents costs from falling on the community at large. Boulder County’s state court lawsuit against Suncor Energy and Exxon Mobil Corporation, originally filed in 2018, identifies intensified wildfire risk among the climate-related harms requiring compensation. According to the court filings analyzed by Camacho and Glicksman, the Marshall Fire ignited in Boulder County on December 30, 2021, driven by hurricane-force winds and vegetation desiccated by years of drought. The fire burned more than six thousand acres and destroyed over one thousand homes in a matter of hours, marking the most destructive wildfire in Colorado history.
Allegations of Corporate Concealment
The legal claims extend beyond standard product liability. According to the complaints filed by local governments, fossil fuel companies spent decades concealing the relationship between their products and climate harm while actively marketing those products to an uninformed public. The lawsuits allege a sustained campaign of corporate deception designed to allow companies to continue profiting while climatic consequences mounted. Scholars note that if this corporate fraud and intentional suppression of climate data are proven in court, the legal case for allocating adaptation costs to oil companies is significantly strengthened. Such concealment allegedly deprived the public, policymakers, and communities of information necessary to respond to climate change in a timely manner that could have reduced subsequent disaster response costs.
International Norms and Domestic Enforcement Hurdles
While the polluter-pays principle enjoys broad support in international environmental instruments, it lacks the status of a customary international norm due to varying state interpretations. Mechanisms such as taxation, charges, and liability laws often prove more effective when deployed within national legal systems rather than internationally. Within the context of the Paris Agreement and international climate law, greenhouse gas emissions from developed countries largely determine whether global temperature increases remain capped at 1.5 degrees Celsius above pre-industrial levels.
