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.
