The Colorado Sierra Club is a powerful collective of more than 100,000 grassroots changemakers working together across the state to advance climate solutions, act for justice, get outdoors, and protect lands, water, air, and wildlife. We are an organization that believes in the power of working together to make change happen.
As the Colorado chapter of the national Sierra Club, the largest and most influential grassroots environmental organization in the U.S., together for over 126 years we have helped shape the way people can participate in local, state, and national advocacy and policy work, so that we can better protect the planet—and each other.
We have a lot more change to make, because so much more is possible. We work alongside other local and national groups because we are more powerful together.
