The Colorado Sierra Club is led by volunteers and staff across the state with the amazing championing of our 93,000 members and supporters.
For over 60 years we have led the charge on preserving 1.2 million acres of public lands, shut down and helped confirm a retirement date for seven coal plants, and worked to pass climate legislation focused on holding oil and gas companies accountable, reducing climate emissions through transportation, and protecting wildlife throughout the state.
Together, we offer a wide array of activities to engage our communities across the state to explore, enjoy, and protect our shared environment.
Our Core Values
To be more responsible and accountable allies as individuals and as a Sierra Club community at large, we commit ourselves to live our five values: anti-racism, balance, collaboration, justice, and transformation. These drive the decisions we make as we fight for a livable planet for all. Learn more about our values in detail at www.sierraclub.org/sierra-club-values.
Our Chapter Priorities
The Colorado Sierra Club's core priorities are focused on climate and energy, the conservation of lands, water, and wildlife, and helping to build a pro-environment and effective Colorado Executive and Legislative branch. This looks like,
- Phasing out fossil fuel development
- Ensuring a just transition off of coal and fossil gas to renewables
- Holding the worst polluters accountable for their legacy of pollution
- Restoring crucial and endangered species to our ecosystem
- Ensuring Coloradans have access to clean water
- Electing more pro-climate justice leaders
- ...and more!
