Ecological forest thinning and prescribed burns lower insurance premiums significantly
Willis Towers Watson and The Nature Conservancy released a report showing a 41% reduction in residential insurance premiums through ecological forestry practices. The study reveals that methods like controlled burns and ecological thinning can significantly lower the risk of severe wildfires. Implementing these practices could save an estimated $21 million annually in insurance costs for 81,000 homes in specific areas. The report also suggests that insurance savings could fund further ecological treatments, creating a beneficial cycle for communities.
- 41% decrease in residential insurance premiums due to ecological forestry practices.
- $21 million in annual insurance savings for homes in wildfire-prone areas.
- Introduction of innovative parametric insurance products for wildfire risk.
- High wildfire risks make insurance difficult in certain areas, leading to increased non-renewals.
New study finds
ARLINGTON, Va., July 07, 2021 (GLOBE NEWSWIRE) -- Willis Towers Watson and The Nature Conservancy (TNC) have published an analysis that shows how ecological forest management, which reduces the risk of severe wildfires in fire-adapted forests, can be combined with insurance to reduce insurance costs significantly.
By modeling the impact on insurance of controlled burning and ecological thinning of overgrown forests, researchers at TNC and Willis Towers Watson were able to quantify insurance premium savings. In turn, these savings could be used to fund further investments in sustainable forest management.
The report, Wildfire Resilience Insurance: Quantifying the Risk Reduction of Ecological Forestry with Insurance, finds the practice known as ecological forestry, which includes prescribed burns and the removal of smaller trees and other vegetation in overgrown forests (i.e., thinning), leads to decreases in total insurance premiums by
The report explores how the insurance savings from ecological forestry could be captured and applied to pay debt service on bonds, which would be issued to pay for ecological forest treatment. In this way, the insurance savings can contribute to funding or financing the ecological forest treatment, creating a “virtuous circle.”
For the first time, the project tested “parametric” insurance as applied to the intensity and acreage of wildfires, resulting in a reduction in both losses and premiums. Such a parametric product, which can provide instant access to funds to pay for costs not covered by indemnity insurance, would be new to the market and is an innovative way for insurers to cover fire risk.
The project used an ecological forest restoration project in the watershed of Placer County Water Agency in the Tahoe National Forest in northern California. The researchers found ecological forestry in the watershed reduced the risk of wildfire substantially for the 81,000 homes in and around the watershed, which in turn could reduce aggregate home insurance premiums by
“For the first time we demonstrated insurance modeling and pricing can account for the severe wildfire risk reduction benefit of ecological forest treatment,” said Dave Jones, senior director of Environmental Risk, The Nature Conservancy, and former California insurance commissioner. “These widely supported forest treatment practices, prescribed burns and ecological thinning provide the triple benefit of improving forest health, decreasing the risk of catastrophic wildfires and providing a pathway to keep insurance available. Insurers’ models do not currently consider forest treatment, but now that we have shown it can be done, we expect insurers will begin doing so.”
Due to the high risk of wildfires and associated losses, insurers are finding it a challenge to write insurance in areas at risk of wildfire. In late 2020, the California Department of Insurance reported that between 2018 and 2019, non-renewals by insurers increased by
“Wildfire risk in California and across the western United States is becoming uninsurable due to increasing risks of climate change and overgrown forests laden with fuel,” said Dr. Nidia Martínez, director of Climate Risk Analytics, Willis Towers Watson. “The state-of-the-art analytics described in this report provide insurers with tools to incorporate the true value of wildfire risk reduction through ecological forestry into underwriting decision making. The product innovations we present offer new approaches to protecting communities and businesses in the Wildland-Urban Interface through insurance.”
“If we want to continue with insurance in these areas and reduce loss of life and property, we need a lot more private and public funding for ecological forestry in national and other forests,” said Jones. “This spending really is an investment in the future of these areas.”
The case study results are applicable to other similarly forested regions in California and other western states. The work also opens the possibility to consider combining nature-based risk mitigation and risk transfer in other fire-prone regions around the world.
The report also includes a series of recommendations, including for federal, state and local policymakers to fund more forest treatment in national and other forest lands, so that communities and businesses can see the resulting risk reduction and insurance benefits shown in the paper.
