California’s Greenhouse Gas Reduction Fund (GGRF) is a climate tool that cuts pollution while delivering real benefits back into your daily life: cleaner air, safer communities, and investments that can lower costs over time. The GGRF is funded by Cap-and-Invest, which raises money from major polluters through an auction system, to support climate change solutions that promote health and affordability in California.
Since the first funds were dispersed in 2014, California Climate Investments (funded by Cap‑and‑Invest auction proceeds deposited into the GGRF) have implemented more than $12.8 billion across the state. In 2024 alone, programs implemented nearly $1.9 billion through about 11,700 new projects. (California Climate Investments – 2025 Annual Report)
Now, that stream of community funding is at risk because the California Air Resources Board (CARB) is considering oil industry-backed amendments that will undermine the Cap‑and‑Invest program. The Board will vote on this proposal on May 28, 2026. (CARB)
TL;DR: What is the GGRF?
California’s Greenhouse Gas Reduction Fund (GGRF), supported by Cap-and-Invest auction proceeds, has implemented more than $12.8 billion in community climate projects that lower costs and improve health for Californians. The California Air Resources Board (CARB) is considering an oil industry-backed Cap-and-Invest amendment that would undermine the program, slash billions of dollars from the GGRF, and gut funding for key climate programs. CARB is scheduled to vote on this proposal on May 28, 2026.
Quick Summary: How the GGRF Works & What’s At Risk
California gets investments funded by major polluters via auction proceeds from Cap-and-Invest, deposited into the GGRF, supporting statewide programs through California Climate Investments.
Since 2014, the GGRF has funded programs that, according to the 2025 California Climate Investments Annual Report:
- Conserved and restored 1.6 million acres of land
- Contracted 13,600+ affordable housing units
- Saved Californians $30 billion in travel costs
- Issued 560,000+ rebates for electric cars and clean energy appliances
- Invested in wildfire prevention, forest health, and prescribed burning
- 73% of investments benefitting priority populations
- Are projected to reduce air pollution by 116.1 million metric tons
The California Air Resources Board (CARB) that manages Cap-and-Invest, which funds the GGRF, is now considering an oil-backed proposal for rule changes. This proposal would slash billions of dollars from the state budget in a time when costs are higher than ever across the state and gut key GGRF-funded climate programs that everyday Californians rely on. (Alex Nieves, Politico)
CARB’s proposed rule changes could reshape how the program functions, cut corners to benefit the oil and gas industry, and erase affordability programs that Californians rely on—and they’re voting on it at a board meeting on May 28, 2026.
What is the GGRF & How Does It Benefit Me?
Think of the Greenhouse Gas Reduction Fund (GGRF) as California’s climate fund: money raised from the Cap‑and‑Invest system is deposited into the Greenhouse Gas Reduction Fund, then distributed to programs that deliver public benefits.
Here’s what that can mean for you and your neighbors:
- Cleaner air and healthier neighborhoods: California Climate Investments are designed to deliver economic, environmental, and public health benefits, including meaningful benefits for disadvantaged and low‑income communities.
- Real projects you can point to: California’s reporting tracks implemented projects and outcomes, showing how funds translate into on-the-ground improvements statewide.
- Climate progress with scale: Implemented projects are expected to reduce greenhouse gas emissions over their lifetimes, reflecting concrete climate returns from community investments.
Here are just a few programs funded by Cap-and-Invest and the GGRF that you might have benefitted from:
- Automatic energy bill credits through the California Climate Credit that has put $16 billion in bill refunds back in California households’ pockets. (Governor Gavin Newsom – Press Release)
- Clean transportation solutions like electric school buses, zero-emission delivery vehicles, and rebates for electric cars and plug-in hybrid cars. (California Climate Investments and California Air Resources Board)
- Micro mobility projects like rebates for electric bikes (e-bikes). (California Air Resources Board)
- Clean, secure, and affordable drinking water in communities and Tribal governments across California. (California Climate Investments)
- Rebates and increased access for heat pumps in residential communities to make these electric, clean A/C and water heater units easy and affordable to install. (TECH Clean California)
Public health benefits from reduced exposure to pollutants because of GGRF investments show health care benefits valued at $15.3 billion, notably:
- 257,920 avoided asthma symptom cases in children (California Climate Investments)
- 164,343 avoided work loss days (California Climate Investments)
And the benefits are broad and statewide. California Climate Investments span 117 programs administered by 27 agencies, which is why so many communities across the state feel the effects, from transportation to resilience to housing-related investments. (California Climate Investments)
Why This Funding Is Under Threat Right Now
CARB is in a formal rulemaking process to update the Cap‑and‑Invest Regulation (formerly Cap‑and‑Trade). The California Air Resources Board (CARB) is considering a proposal that would undermine Cap-and-Invest, cut corners to benefit the oil and gas industry, compromise our climate progress, and erase billions of dollars in revenue. (Alex Nieves, Politico)
For more than a decade, Cap-and-Invest has been one of California’s most cost-effective climate tools. This program sets limits on emissions from major polluters and funds the Greenhouse Gas Reduction Fund (GGRF) that supports communities in the transition to clean energy, builds climate resilience, and expands access to affordable housing and public transportation.
The changes that CARB is proposing will undermine Cap-and-Invest’s performance and significantly reduce billions of dollars funding to the GGRF that flows into climate investments.
In short: when the rules tilt toward polluter-friendly loopholes, everyday Californians risk losing out on the benefits the GGRF helps fund.
