The Case
Pacific Gas and Electric, California’s largest utility serving approximately 16 million customers, filed for Chapter 11 bankruptcy protection in January 2019. The trigger was wildfire liability. PG&E’s equipment had been linked to multiple catastrophic blazes, most devastatingly the Camp Fire of November 2018, which killed 85 people and destroyed the town of Paradise, the deadliest and most destructive wildfire in California history.
At the time of filing, PG&E faced 750 civil lawsuits and estimated wildfire liabilities of up to $30 billion, far exceeding its insurance coverage. The company ultimately reached a $13.5 billion settlement with wildfire victims and emerged from bankruptcy in 2020 under state supervision.
The legal mechanism that made PG&E uniquely vulnerable was California’s doctrine of inverse condemnation: utilities are strictly liable for damage caused by their equipment, regardless of whether negligence is proven. As climate change extended California’s wildfire season, through longer droughts, stronger winds, and higher temperatures, this doctrine transformed physical climate risk into existential financial exposure.
Columbia University’s Climate School described PG&E as “the first climate change bankruptcy.” The case demonstrated that the theoretical link between rising temperatures and financial collapse was not abstract, it was concrete. Traditional utility valuation models had not priced in catastrophic wildfire liability, and investors were caught largely off-guard.
The bankruptcy accelerated regulatory interest in mandatory climate risk disclosure, particularly for asset-intensive sectors with physical exposure. The TCFD and IFRS S2 frameworks’ emphasis on physical risk scenarios owes a direct debt to cases like PG&E, which proved that physical risks are financial risks, present-day solvency threats rather than future theoretical concerns.

- Nov 2018 Camp Fire ignited by faulty PG&E transmission line, 85 killed, town of Paradise destroyed
- Jan 2019 PG&E files for Chapter 11 bankruptcy facing $30B in estimated wildfire liabilities
- 2019 750 civil lawsuits consolidated; $13.5B settlement reached with wildfire victims
- 2020 PG&E emerges from bankruptcy under state supervision and probation agreement
The Debate
PG&E’s bankruptcy raises a systemic question: should a single utility bear the financial cost of climate-driven disasters it did not cause? California’s inverse condemnation doctrine holds utilities strictly liable for wildfire damage, regardless of fault. Critics argue this framework was designed for a different climate, one where wildfires were occasional and manageable, not annual and catastrophic. Holding a utility responsible for damage driven by global temperature rise creates an unsustainable liability model.
Defenders of the doctrine counter that someone must bear the cost, and the entity whose equipment ignited the fire is the most logical candidate. If utilities cannot be held liable, the cost falls entirely on homeowners, insurers, and taxpayers, none of whom chose to defer infrastructure maintenance or operate ageing equipment in increasingly dangerous conditions. PG&E had a documented history of underinvestment in safety.
The deeper debate is about disclosure and foresight. PG&E’s investors were caught off-guard because neither the company nor the market had adequately modelled catastrophic wildfire exposure. The case is now used to argue for mandatory physical risk disclosure, but it also raises the question of whether disclosure alone is sufficient, or whether some climate risks are simply too large and too fast-moving for markets to price correctly.
