Webinar: Why California Needs the Polluters Pay Climate Superfund
2025-05-22 10:00 - 11:30 | https://350contracostaaction.org/event/webinar-why-california-needs-the-polluters-pay-climate-superfund/
California wildfires are causing catastrophic damage—with a price tag around $250 billion. But why should taxpayers carry that cost while Big Oil gets a free pass?
Join us and our hosts at The Climate Center for a timely webinar on SB 684 (Menjivar) and AB 1243 (Addis)—legislation that would make fossil fuel companies pay into a Climate Superfund to support disaster recovery, frontline communities, and real climate action.
Hear from bill authors, economists, and advocacy leaders on how this bold plan can deliver justice and resilience for Californians.
Register here for the Climate Center Superfund webinar.

May Climate Circle: Flipping the Grid--How Neighborhood Power Can Keep the Lights On
2025-05-05 12:00 - 13:00 | Zoom Meeting
Join us for the May 5 Climate Circle. This month’s topic focuses on flipping the grid with community-powered Distributed Energy Resources (DERs) to keep the lights on when neighborhood power goes down.
When the Power Goes Out
Has your power gone out during a heatwave or wildfire warning—spoiling food, shutting off fans, or disconnecting critical medical equipment? A local, community-based Distributed Energy Resources network can pick up the slack when the Big Grid fails.
As the climate crisis accelerates, so do the threats to our electricity system. With more heatwaves, droughts, and storms, utilities like PG&E are shutting off power more often to prevent wildfires. At the same time, more people are switching to electric vehicles, stoves, and heaters—putting even more pressure on the grid. And it’s not just homes and cars—massive new data centers across the country consume enormous amounts of electricity to power cloud computing, AI, and the internet we all rely on. That demand is straining the grid even further.
Can We Build Power in Our Own Neighborhoods?
It’s not a quick fix, but the answer is yes. While it takes effort, collaboration, and some investment, local communities are already starting to make it happen. By tapping into clean energy solutions like rooftop solar, small wind installations, home batteries, electric vehicles, and smart appliances—together, these are known as Distributed Energy Resources (DERs)—we can create local power networks that make our neighborhoods more resilient—even when the grid goes down. The City of Richmond already uses such a network to provide more resilient and flexible power to its residents.
Join us on May 5 for a lively discussion on how communities are flipping the grid with DERs, and what we can do in our own neighborhoods. Whether you’re just getting familiar with energy issues or you’ve studied them in depth, there’s plenty to share and learn from each other.
Sign up here to receive the discussion materials and Zoom link.
Come curious. Leave inspired. Everyone is welcome.
The Contra Costa Climate Circle is a Zoom meeting for the climate concerned. Come connect with like minded folks and discuss current events in a safe and friendly space, each month, the first Monday, from 12-1 pm. All are welcome. We look forward to meeting you!

CANCELLED! Congressman DeSaulnier Hosts Environmental Town Hall and Fair May 3
2025-05-03 13:30 - 16:30
Update April 30, 2025: We received notice this afternoon that the Congressman has had to cancel this event.
From Congressman DeSaulnier:
Here in California, we’ve seen firsthand the disastrous effects of climate change from devastating wildfires to more extreme temperatures. Amid this climate crisis, the Trump Administration’s policies have undermined the tools we have to address global warming, including rolling back environmental protections and withdrawing from the Paris Climate Agreement.
To discuss the path forward and my efforts in Congress to fight back against the Administration’s dangerous actions, I am hosting an outdoor Environmental Town Hall and Resource Fair this Saturday, May 3rd in Oakley.
Starting at 1:30 p.m., local agencies and organizations will share resources on their work to protect the environment. At 2:00 p.m., I will provide an update on my efforts to protect our planet, and we will hear from several local agency leaders about the work being done at the local level. We will also take your questions.
This event is RSVP only and the venue has limited capacity. Click here to RSVP. Confirmed attendees will receive more information, including the exact location, prior to the event.
I hope you will join us for this conversation.

That’s why we’re inviting you to our webinar: Cleaning Up California’s Manufacturing Sector: 🔥Clean Heat for Communities and Workers
Together we’ll explore how electrifying industrial builders can:
✅ Protect public health and frontline communities
✅ Safeguard workers
✅ Slash climate pollution
✅ And move us toward a cleaner, more just future
You’ll hear from advocates, experts and organizers leading this fight—whether it’s pushing for stronger clean heat rules in California’s Bay Area or building momentum for policies nationwide.

This month, the focus is on wildfire. Wildfires in California in the past 10 years have destroyed thousands of homes and burned millions of acres of forest, polluting the air we breathe and releasing harmful carbon dioxide into the earth’s atmosphere.
As a result of catastrophic wildfires, homeowners’ fire insurance is becoming prohibitively expensive, or unavailable. How could future local wildfires impact us and our neighborhoods? What can we do to make our homes and communities more fire safe?
The Climate Circle takes place the first Monday of the month from 12-1pm.
Register here to receive the discussion materials and Zoom link.
