AB 1666: Forest management: biomass innovation parks: wood products.
What AB 1666 does, verified October 2, 2026
The bill aims to create biomass innovation parks to utilize woody biomass from high fire hazard zones in California. The parks will process only wood waste that originated in California and use non-combustion technology to convert it into carbon-beneficial products or end uses. Each park must establish a community benefits program and adhere to specific guidelines. The parks will also contribute to regional wood availability assessments and tracking of forest biomass origins. Additionally, the bill requires the state to publish life-cycle emissions assessments and consider incorporating durable wood products in housing grant programs. The state will also track and authenticate forest biomass origins and deliver a report on the identified parks by December 31, 2027.

CALIFORNIA LEGISLATURE— 2025–2026 REGULAR SESSION
Assembly Bill
No. 1666
| Introduced by Assembly Member Rogers |
January 29, 2026 |
An act to add Chapter 7 (commencing with Section 4820) to Part 2.5 of Division 4 of, and to repeal Section 4825 of, the Public Resources Code, relating to forestry.
LEGISLATIVE COUNSEL'S DIGEST
AB 1666, Rogers. Forest management: biomass innovation parks: wood products.
Existing law establishes the Department of Forestry and Fire Protection (CAL-FIRE) in the Natural Resources Agency and requires CAL-FIRE to coordinate programs of fire protection, fire prevention, pest control, and forest and range maintenance and enhancement. Existing law requires the Secretary of the Natural Resources Agency to establish a working group on expanding wood product markets that can utilize woody biomass, especially biomass removed from high fire hazard zones, as determined by CAL-FIRE.
This bill would enact the Biomass Innovation Parks Act, which would establish the Biomass Innovation Park Grants and Financing Program, to be administered by the agency. The bill would require the agency, in coordination with the Department of Food and Agriculture (department) and CAL-FIRE, on or before September 30, 2027, to identify one or more biomass innovation parks, as provided. The bill would require the agency, in coordination with the department and CAL-FIRE, to develop guidelines and solicit proposals from an eligible applicant, as defined, to develop, operate, and manage a biomass innovation park, as provided. The bill would require the guidelines to include specified things, including, among other things, that each park shall only process wood waste, as defined, that originated in California, that each park only host projects that use a noncombustion technology to convert wood waste into carbon-beneficial products or end uses, as specified, and that each park establish a community benefits program. In order to facilitate a planning process for identifying parks, the bill would authorize the agency, in coordination with the department and CAL-FIRE, to develop guidance on specified things, including, among others, guidance for a public agency and private industry to partner on a park proposal.
This bill would additionally require the agency, in coordination with the Office of Land Use and Climate Innovation and CAL-FIRE, to, among other things, develop regional wood availability assessments and to adopt a tracking system to trace and authenticate forest biomass origins. The bill would require the agency to deliver a report to the Legislature on or before December 31, 2027, containing information pertaining to the identified parks.
The people of the State of California do enact as follows:
SECTION 1.
(a) The Legislature finds and declares all of the following:(1) California is currently facing a wood waste crisis, whereby tens of millions of tons of forest biomass from wildfire prevention, wildfire recovery, and agricultural biomass from crops, orchards, and vineyards are being piled and burned or left to decay in place every year, causing significant carbon and air pollution.
(2) Existing state policy, including the “2022 Climate Change Scoping Plan for Achieving Carbon Neutrality” adopted by the State Air Resources Board, identifies the need to collect and convert these residues into carbon-beneficial end uses, including wood products, including mass timber, clean fuels, including biomethane, clean hydrogen, and sustainable aviation fuel, and carbon dioxide removal.
(3) Existing state policy, Resolution 22-21 “2022 Climate Change Scoping Plan for Achieving Carbon Neutrality,” adopted December 15, 2022, by the State Air Resources Board, provides that the state board has determined that the “expansion of biomass combustion for energy production should not be pursued and opportunities for noncombustion biomass solutions should be prioritized.”
(4) Existing state policy, “Enhancing California’s Resiliency to Natural Catastrophes” developed by the California Earthquake Authority pursuant to Senate Bill 254 (Chapter 119 of the Statutes of 2025) and “California’s Wildfire and Forest Resilience Action Plan” developed by the Governor’s Wildfire and Forest Resilience Task Force, both identify the establishment of an in-state bioeconomy as a key strategy to reduce catastrophic wildfire risk by removing hazardous residues and reducing the cost of forest treatments.
(5) Existing state policy, including approved Jobs First regional plans for the Sierra Nevada, north state, northern San Joaquin Valley, central San Joaquin Valley, and County of Kern, identify biomass solutions as a strategic priority to reduce pollution, reduce catastrophic wildfire risk, and create economic and workforce development opportunities.
(b) It is the intent of the Legislature to incubate and expand a sustainable bioeconomy in California, consistent with existing state plans and goals, by establishing one or more biomass innovation parks in regions that serve as centralized hubs to deliver and efficiently process residues into a suite of needed clean products and end uses that reduce wildfire risk, reduce air and carbon pollution, provide jobs and community benefits, and support world-leading clean technology innovation. In order to support broader bioeconomy development, additional state policies that establish low-carbon product revenue incentives and offtake opportunities and secure long-term forest biomass feedstock supply are needed to address key obstacles to project financing.
