Bill Overview
Analyzed Economic Effects
12 provisions identified: 10 benefits, 0 costs, 2 mixed.
Cleaner air in local communities
The law continuously provides $250 million for community air protection. The Air Resources Board funds incentives to cut pollution from vehicles and equipment, and supports local air districts. Funding comes after higher‑priority allocations and targets disadvantaged and low‑income areas.
More funding for forest fire prevention
The state continuously provides $200 million to Cal Fire. 82.5% funds healthy forest and fire prevention programs. 17.5% funds prescribed fire, fuel reduction, and related research and monitoring. Spending must reduce greenhouse gases and aid disadvantaged or low‑income communities.
More help for safe drinking water
The state transfers $130 million to the Safe and Affordable Drinking Water Fund. The money pays for drinking‑water projects under the state program after higher‑priority allocations. It focuses on communities that lack safe water, often low‑income or rural areas.
More money for trains and transit
The state provides $1 billion to high‑speed rail for land, design, construction, and loan repayment. It also sets aside $400 million for transit and intercity rail projects and $200 million for low‑carbon transit operations, distributed under program formulas. Lawmakers state an intent to spend $125 million on transit passes in 2026–27. These funds follow program rules and flow after higher‑priority allocations.
More money for affordable housing
The law continuously sets aside $800 million for the Affordable Housing and Sustainable Communities Program. At least 10% must go to affordable housing. Money is used after higher‑priority allocations and under program rules.
New rules for climate fund spending
The law reserves $1 billion for the Legislature to allocate in the budget, with stated priorities for 2026–27. If annual proceeds are short after higher‑priority items and state operations, the Department of Finance reduces paragraph (1) appropriations proportionally. Any surplus beyond required allocations can be spent through the Budget Act or another law. Section 39719 becomes inoperative July 1, 2026, ending the current continuous appropriation structure.
State covers former SRA fire fees
Beginning in the 2026–27 fiscal year, state funds first replace revenue from the State Responsibility Area fire prevention fee. This shifts money to cover what the fee supported. The law does not set a per‑household amount.
Planned 2026–27 climate research and parks
For 2026–27, lawmakers intend to direct $85 million to a chosen entity for climate tech research and deployment. They also intend $25 million as seed funding for a UC Climate Research Center and $15 million to rebuild Topanga Park. These intentions draw from the $1 billion reserve and depend on later budget choices and allocation order.
Stronger rules for carbon offsets
The Air Resources Board must update all offset protocols by January 1, 2029 using the best available science. It must consider other carbon markets, Paris Agreement Article 6.4, research, and industry best practices. The Board must also review all protocols by January 1, 2034 and every five years after that.
Climate funds must cut emissions or help resilience
The law requires listed funds to reduce greenhouse gases or improve climate adaptation and resilience for disadvantaged or low‑income communities. Agencies may meet budget reporting rules by explaining how each expense improves resilience.
Top-priority backfill for tax program
Beginning in the 2026–27 fiscal year, funds are allocated to cover amounts identified in state tax law (Revenue and Taxation Code Section 6377.1(g)(3)(A)). This is a high‑priority use of the fund and does not create a household payment.
Start-up funds for climate policy office
Starting in 2026–27, the law sets aside $3 million to start the Legislative Counsel Climate Bureau. Agencies cannot spend this money until a law defines the bureau’s roles and duties.
