Together we can help build a super-charged global climate movement at the local level by engaging with our local Sacramento area community members and organizations.

We reached 400 ppm in 2013. Only three years later in 2016, scientists said we may never return to levels below 400 ppm. While the situation is more urgent than ever, together we can create solutions to reduce the impacts of climate change for current and future generations.

We speak when we need to speak, and listen when others need to be heard. There's always something new to learn and and an old lesson to remember.

And no lie, climate activism can be rough, but that's why we like to play and have fun with the work we do. We can look at climate change as an opportunity to improve the planet we depend on, and support each other in our shared mission.


If you don't have the capacity right now to volunteer, we also accept donations with plenty of gratitude!

Edward Abbey once said “sentiment without action is the ruin of the soul.” I discovered 350 Sacramento from a link off the 350.org website and have been involved ever since. My involvement with 350 Sacramento has not only provided me a meaningful way of taking action against climate change, it allowed me to get to know some amazing people.

She became passionate about sustainability after getting more involved in the textile industry, and learning the social and environmental disasters that have expanded from our fast fashion lifestyle and culture. Her experience leading the sales department and fundraising for for-profit businesses will be beneficial in her new Treasurer role.

I became a volunteer with 350 Sacramento in January 2017. I had been concerned about the air quality in the Sacramento region for many years, so I decided to get involved. I don’t have a background in environmental science, so the learning curve has been a steep one for me. As I continue to learn and work alongside the other dedicated volunteers, I’ve found there’s a place for each of us to do whatever we can to reduce greenhouse gas emissions in Sacramento. 

Tina Gallier

Member at Large |
My B.A. is in microbiology, and I am a science and nature lover. So saving our precious Earth from climate change is why I get up in the morning. The success our organization has had or contributed to the mitigation of greenhouse gas emissions is what keeps me going. People can really make a difference if they get together in large numbers and work cooperatively.

I'm a recently barred attorney with a background in environmental and Water Law, especially with an interest in tribal rights and environmental justice. I joined 350 recently because I want to be more directly involved in advocating for better climate policy.
