2026 Priority California Climate Bills: We're Celebrating!

Governor Newsom has wrapped up his bill-signing marathon at last. On the very last day he signed ALL of Climate Action California's priority bills still on his desk, including some that the investor-owned utilities—especially the gas utilities—have opposed througout the session. GREAT WORK EVERYONE!

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.

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.

High time to make polluters pay for climate harms

As climate disasters grow more extreme, we need to hold the fossil fuel industry accountable. Who better to make families and communities whole after a climate-fueled fire or flood?  Climate Superfund legislation will keep on coming back in the state legislature until we pass it at last!

How nature is vital to the climate fight

Andy Shrader and Alice Kaufman explain why preserving natural resources and biodiversity is essential to drawing down emissions, how land-use decisions are key to climate mitigation, and how we can protect nature so it protects us.
