We are a grassroots movement working to build a fossil-free future powered by 100% renewable energy, and we empower communities across Colorado to join together to fight for
environmental justice. Through our volunteer-led teams, we use a variety of tactics, such as legislation and direct action, to take on the climate crisis.
Together we have the power to solve the climate crisis – join over 20,000 Coloradans who have signed up to take action!
We are an independent state affiliate of the international environmental organization 350.org. Together, 350 is organizing around the world to end the use of fossil fuels and secure a just transition to renewable energy.
No matter what level of commitment you’re ready to take, there is a place for you in our movement! You can donate, sign petitions, join a local team, attend educational events, be trained to be an organizer in your community, and more.
Schedule a 1-on-1 with our volunteer coordinator or join a campaign today!

Our 350 Colorado Springs Team secured a just transition off of coal in Colorado Springs, with early closures for two dirty coal plants.
We launched a massive Get Out the Vote effort, our volunteers reached over 97,000 likely environmental voters to help them make it to the polls.
Boulder County becomes the first in the nation to call on insurance companies to stop insuring and investing in fossil fuels, passing a historical resolution on climate change and insurance.
With the help of organizations like 350, Boulder County’s updates of its oil and gas development rules “will now be the strongest in the state.”
Campaigns are one of the most effective tools we have to make real changes. Getting started with a campaign can be as simple as signing a petition, or as involved as helping to draft legislation. 350CO has a place for any level of contribution.
Join us in building the movement to solve the climate crisis through elevating climate justice, working to keep fossil fuels in the ground, advancing fossil fuel divestment efforts and promoting local solutions.
The easiest way to make a positive difference every day. Donate to invest in a just and equitable transition off fossil fuels.
