Climate action is one of the most powerful ways to improve your community, and 350 Contra Costa has plenty of ways to plug in. In 2025, our all-volunteer teams fought for cleaner air, cleaner water, and a healthier local environment. We’re going even stronger in 2026. But first, here’s how we showed up for climate action in Contra Costa last year.

• Hosting a booth at farmers’ markets and outdoor events, where neighbors could sign postcards urging their state representatives to pass the Make Polluters Pay Superfund Act and engage with us about other climate initiatives on their minds 
• Continuing our leading role in the East Contra Costa Healthy Homes Collaborative, which, over the next several years, will provide funding for the electrification of some income-qualified homes in Antioch and Pittsburg
• Facilitating Climate Circles, where we invited county residents concerned about climate change to discuss current climate issues in virtual meetings
• Publishing letters to the editor in local newspapers highlighting climate issues and solutions
• Talking with our local city councils, county board of supervisors, and state legislators about meaningful climate legislation to protect our communities
• Mobilizing concerned citizens to speak up for cleaner air at Bay Area Air District meetings and other regulatory bodies

That’s what 2025 looked like. Here’s what we’re building next, and where you come in.

As a community climate activist in Contra Costa County, you can engage neighbors and elected officials on climate issues and real solutions. The tools are varied—in-person outreach, letters to the editor, blogs, newsletters, and social media—and there’s never been a better time to use them.

Accelerating Community Climate Activism into 2026

All of our 2025 initiatives continue in full force, and there’s a place for you in every one of them. With 2026 now fully underway and an important election year upon us, there’s even more to choose from, starting with supporting climate champions running for office.

In conjunction with 350 Bay Area Action, we are researching candidates and elected representatives at the local, county, state, and federal levels to identify and endorse candidates committed to climate action. We will actively promote their campaigns through door-to-door outreach, postcards, our newsletter, social media  and our website, and we’re looking for volunteers to get involved.

We’re not stopping there, however. We’ve launched two exciting new programs this year: our Community Climate Forum and our new City Liaison program, both mobilizing residents to drive climate action at the local level, where roughly 70 percent of global emissions occur.

Let’s Talk Climate

Our Community Climate Forum brings Contra Costa neighbors together every other month for a one-hour online conversation focused on key climate and clean-air campaigns happening right here in our region. Each forum opens with a short overview of a timely topic, moves into open discussion, and closes with simple actions participants can take to help move solutions forward. It’s accessible, engaging, and a great entry point for anyone new to climate action. We’d love to see you there.

Climate Action City by City

We are assembling City Liaison teams of 2-3 volunteers in each of Contra Costa’s 19 cities to monitor, track, and advocate for climate action at the local level—where it matters most. 

Each team will be supported by its own city-focused web page discussing current climate issues and a path forward to a healthier climate future in that community.

We are actively seeking city liaisons to contact their mayors and city council members on behalf of environmental proposals and encourage their neighbors to do the same. Elected officials listen to people who live in their cities, so city liaisons play a vital role.

Liaisons will advocate for climate-forward policies with their city councils, engage their neighbors along the way, and build lasting relationships with local elected officials and other volunteers. The time commitment is light—just 1 to 5 hours per month—and the difference you can make is real.

Our climate work doesn’t stop at city limits. We are equally committed to working at the county level and in unincorporated areas of Contra Costa, home to some of our most vulnerable communities, to advance meaningful climate goals across the region.

And the best part? All of this work is serious—and seriously fun. Come be a part of it.

Join Us in Working for a Cleaner Future

There are many ways to get involved. We’re pushing forward on multiple fronts, including:

• Backing climate champions—researching, endorsing, and volunteering across local, state, and federal races
• Making Contra Costa homes and buildings fossil-fuel-free
• Tracking and advocating for California legislation that would reduce greenhouse gas emissions, promote clean energy, and hold polluters accountable
• Monitoring energy and transportation actions at both the local and state levels
• Helping our local communities achieve a just transition as refineries close

If you care about our air, water, and environment, you’re already a climate activist—and we want you on our team. Join us on any of these projects and you’ll find the work rewarding, the connections meaningful, and the people around you inspiring.
