Discover how Willis and The Nature Conservancy are redefining wildfire insurance with their groundbreaking initiative.
In an effort to address the escalating challenges in California’s insurance market, Willis, a branch of WTW, in collaboration with The Nature Conservancy (TNC), has launched a groundbreaking $2.5 billion wildfire insurance policy. This policy aims at reducing premiums significantly through strategic forest management practices.
The insurance policy, tailored for Tahoe Donner Association—a private homeowners’ association located in Truckee, California—was meticulously developed in conjunction with the Center for Law, Energy and the Environment (CLEE) at the University of California, Berkeley. A key feature of this policy is its innovative approach of linking wildfire mitigation strategies directly to more affordable insurance pricing.
Covering 1,345 acres of Tahoe Donner’s forested and recreational lands, the policy offers a remarkable 39% reduction in premium costs and an 89% reduction in deductibles, compared to conventional policies that do not incorporate forest management measures.
This initiative emerges amidst the ongoing wildfire crisis that has plagued California. The state encountered severe fires in January 2025, notably in the Pacific Palisades, underscoring the pressing need to tackle wildfire risks effectively.
Numerous residents experienced policy non-renewals just weeks prior to these fires, while the state’s FAIR Plan saw a dramatic increase in policy numbers—123% in residential and 161% in commercial policies—between September 2020 and September 2024.
David Williams, the associate director of Alternative Risk Transfer Solutions at Willis, highlighted the critical role of Tahoe Donner’s forest management in mitigating risks. “The forest management work undertaken by Tahoe Donner, which involves removing potential fuel sources that could ignite, has significantly lowered both the premium and deductible of this insurance policy,” Williams stated.
The risk assessment data supporting the premium reduction was provided by Globe Underwriting, formerly known as Forest Re.
Kristen Wilson, lead forest scientist at TNC, expressed the initiative’s broader goal of encouraging more insurers to recognize the advantages of wildfire mitigation efforts. “By introducing this innovative insurance product, we aspire to motivate other insurers to factor in the benefits of thinning and prescribed fires,” Wilson remarked.
Meanwhile, Dave Jones, director of the Climate Risk Initiative at CLEE and a former California insurance commissioner, noted that the policy exemplifies how insurers can continue to provide coverage in fire-prone regions if effective mitigation strategies are employed.
