350 Silicon Valley

350 Silicon Valley is a dynamic, grassroots organization working in San Mateo and Santa Clara counties. We are citizens, just like you, helping to drive a speedy and just transition to clean energy. We are the local affiliate of the international environmental organization, 350.org.

We focus solely on climate because it is about survival, and because it touches all the other things we care about: equity and justice, health, safety, ecological preservation, and many more.
