Wildfires in the U.S. are not just a single natural catastrophe; they are a systemic economic and legal phenomenon. Entire towns are swept away, infrastructure fails, insurers flee high-risk markets, and more complicated, multi-party lawsuits appear before the courts.
According to data from the National Interagency Fire Center (NIFC), since 2000, the U.S. has been reporting above 7 million acres of fire per year, as compared to 3 to 4 million acres of fire per year in the 1980s. More than 10.1 million acres were burned in 2020 alone, and it was one of the biggest wildfire years in the history of the U.S.
This environmental impact is reflected in economic harm as well. According to the National Oceanic and Atmospheric Administration (NOAA), billion-dollar disasters involving wildfires have become more common since 2015. Global reinsurers report that peak years of tens of billions of dollars of insured wildfire losses are now a regular occurrence.
With the increasing fire frequency, number of acres burned, and the risk of wildfire posed by climate, lawsuits have increased accordingly. This article explores seven supportable trends that illustrate why wildfire litigation is increasing in the U.S.
Quick Answer
Wildfire litigation is rising in the U.S. because fire frequency, burned acreage, insured losses, and infrastructure-related liability have all increased significantly over the past two decades. Utility equipment exposure, climate attribution science, insurance disputes, and plaintiff-friendly state laws have transformed wildfire lawsuits into large-scale, multi-party litigation events.
Key Takeaways
- Annual acres burned are roughly double the 1980s average.
- Utilities face strict liability exposure in some states, especially California.
- Insured wildfire losses regularly reach tens of billions in peak years.
- Climate science is increasingly used as evidence in court.
- Public awareness and legal access have increased claim filings.
Trend 1: Wildfire Frequency and More Area of Burns
Summary: Annual wildfire acreage in the U.S. has roughly doubled since the 1980s, expanding financial and legal exposure.
The more the fires, the more the claims, the more the litigation.
According to NIFC statistics, the amount of acreage burned per year is about twice what it was on average in the 1980s. Financial exposure has been increased by the growth of the wildland-urban interface (WUI), as residential land clashes with undeveloped land.
The western states of California, Oregon, and Colorado have been reporting some of the most destructive and large fires in the country.
Important Contributory Factors
- Extended drought conditions
- The increase in average temperatures
- Additional residential crowding in high-risk areas
- Climate change in vegetation dryness
Legal Implications
With increasing frequencies and areas of fire, the litigation of property damage becomes unavoidable and more complicated.
- Explosive growth in property damage claims
- Masses of plaintiffs in nearby burn areas
- Duplicative litigation between utilities, landowners, contractors, and insurers
Trend 2: Utility Equipment is a Major Cause of Disastrous Fires
Summary: Electrical transmission infrastructure has become a primary ignition source in major U.S. wildfires, concentrating legal liability on utilities.
Liability is clustered about utilities.
According to investigations by the California Department of Forestry and Fire Protection (CAL FIRE), electrical transmission equipment has frequently been identified as a source of ignition in large fire outbreaks.
A clear case study: Pacific Gas and Electric Company (PG&E) petitioned for Chapter 11 bankruptcy in 2019 due to the estimated cost of wildfire liabilities, including equipment-related fires, of USD 30 billion or more, including the 2018 Camp Fire.
The same applies to Hawaiian Electric, which has been subjected to widespread litigation after the Maui wildfires in 2023, during which power lines knocked down are still being investigated.
Why Utilities Face Disproportionate Legal Exposure
- California has an inverse condemnation doctrine that bears strict liability
- Utilities work with high-risk infrastructure in fire-prone land
- Their deep financial resources make them key defendants in mass tort wildfire cases
Legal Implications
Utility liability has emerged as one of the main causes of wildfire litigation.
- Consolidated multi-district litigation
- Class-action certifications
- Massive settlement trusts
Trend 3: Higher Rate of Insured Loss
Summary: Insured wildfire losses have increased significantly, creating coverage gaps and driving insurance-related litigation.
Litigation often arises from insurance deficits.
According to sigma catastrophe reports by Swiss Re, insured losses on wildfires in the U.S. in peak fire years have been USD 12–20+ billion during the last ten years.
At the same time
- Since 2022, major insurers have limited new policies in high-risk zones of California
- Wildfire-prone areas have experienced significant premium spikes
- Homeowners are getting underinsured compared with the cost of rebuilding
According to NOAA data, the occurrence of wildfire-related billion-dollar disasters has been increasing more often during the last 15 years in comparison to the 1980s and 1990s.
Legal Implications
Homeowners who are underinsured frequently engage in insurance litigation when the money does not cover the actual construction cost.
- Wildfire policy conflicts regarding replacement value calculations
- Bad-faith insurance litigation
- Disputes relating to business interruption and loss-of-use coverage
Trend 4: Climate Evidence as a Source of Legal Evidence
Summary: Climate attribution science is increasingly used to establish foreseeability and negligence in wildfire cases.
Climate science empowers legal cases.
Attribution climate studies have now estimated the impact of rising temperatures and prolonged droughts to show the probability and severity of wildfires.
