Working to save the best of California for our future

Advocating for science-based solutions to climate chaos

Supporting actions and policies that reduce greenhouse gas emissions

Fighting to reduce air and water pollution harming our communities


How We’re Different


Climate Action California is the only volunteer-led, grassroots climate advocacy group in our state with our approach and focus. We take science-based positions on legislation and policies that 1) reduce short-lived climate pollutants including methane and refrigerants,
2) advance clean transportation and transit, and 3) accelerate an equitable, just transition to the low-carbon future we all need.

What We Do


We work in teams focused on pollutants and emissions sources, and advocate for local, state, and federal legislation and policies that move the needle on climate. We track bills, work in coalition to promote our positions, and keep in close touch with legislators and agency decision-makers on a wide range of issues from building decarbonization and plastics to energy policy and the California budget.

Work With Us!

Let constituents participate in CA Assembly Hearings!

The Capitol building in Sacramento

All Californians should have the opportunity to express their opinion about the legislation that will affect their lives—no matter where they live in the state. Paid lobbyists in Sacramento should not have an advantage over state residents when consequential bills are being voted upon!

Join the Campaign: OPPOSE the 2024 Setbacks Referendum

In 2022 the Legislature passed a long-awaited bill requiring 3200-ft buffers protecting homes, schools, parks, and other "sensitive sites" from the public health effects of oil and gas operations. Immediately, fossil fuel interests bankrolled a referendum  to repeal the law, now on the Nov. 2024 ballot.

Following some important legislative wins in 2023, our volunteer teams are proposing game-changing climate legislation for introduction in 2024. Our proposals are bold and ambitious because it's past time to wait and see what's possible when it comes to reducing emissions!
