Our Mission

350 Contra Costa Action advocates for socially equitable solutions to drastically reduce greenhouse gas emissions and restore natural systems for a healthier, sustainable future for our communities.


Current Climate Crisis

Excessive heat, persevering drought, wildfires, air polluted with smoke and toxic fumesthe impacts of climate change in Contra Costa County worsen with each season. By 2030, a sealevel rise of six to eight inches will flood our bayside communities during storms and high tides. Meteorologists now predict inland flooding in California from “atmospheric river” storms.

There's Still Time to Act

In this climate crisis, we must act decisively to stop the emission of greenhouse gases (GHGs) into our atmosphere. There is still time to avoid the worst. By working together locally, we can create change in Contra Costa County.
