Colorado Sierra Club

Colorado Sierra Club We are a powerful collective of changemakers working together to protect CO's natural resources.

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 mos

t 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.

So, come grab a beer, eat some free food, and spend a couple hours with people who get it. This happy hour is for friends and partners to keep building up community and connection (and maybe some commiserating too).

This list includes coal plants with retirement dates that we must continue to hold accountable.

Colorado has made considerable progress toward our climate goals over the last decade. We cannot, and will not, let massive corporations and the Federal government take us backwards and interfere in our clean energy future.

Leadership matters now more than ever. Here are the Colorado Sierra Club’s 2026 primary election endorsements.

The current push to extend the life of coal in Colorado is not just a policy dispute. It has real consequences, for household budgets, the air we breathe, and the climate commitments we have made.

Help us spread the word on the harms of coal in Colorado!

Over the next few days we will be posting different ways coal plants affect you, your wallet, your health, and the environment. Can you share this to your story to help your community learn more about the harmful effects?

We are currently facing Trump administration executive orders to force coal plants to stay open, along with lawmakers, utilities, and other entities trying to back out of their commitments to retire dirty and expensive coal plants. This increases utility costs for ratepayers (YOU!), pollutes our air; and perpetuates health issues.

Hey absolutely everyone in the Springs! We're hosting a Here and Now Tour stop, which is a community listening session focused on the Make Polluters Pay campaign.

June 17th at 5:30PM in Ga***rd Hall inside of Worner Campus Center at Colorado College (902 N. Cascade Ave.)

RSVP here: https://actionnetwork.org/events/colorado-springs-here-now-tour-building-local-resilience-to-climate-disaster

The climate crisis is here and now – Colorado is already being hit hard by the impacts of an overheating planet - worsening wildfires, drought, pine beetle devastation of forests, 1,000 year floods, mudslides, and impacts to major drivers of our local economies, like agriculture and the winter sports industry. These disasters have already cost Coloradans billions of dollars in damages and adaptation measures.

A 2026 study by the Colorado Fiscal Institute shows that preparing for and responding to climate damages will cost Coloradans $1.5B on average per year moving forward through 2050. Polling in Colorado shows strong public support for ensuring that the biggest historic polluters, most responsible for the climate crisis, pay their fair share of these costs. With states facing budget shortfalls and additional cuts from federal funding, Climate Superfund laws can help reduce the burden on communities and taxpayers by raising revenue to pay for critical infrastructure needs and prepare for extreme weather events.

Climate Superfunds make the biggest historic fossil fuel corporate polluters pay their fair share into a fund that is used by the state and local communities to help cover damages from climate disasters and to support resilience projects. These projects can range from wildfire and flood mitigation, water conservation, heat pumps and efficiency measures to cool schools and homes, and resilience centers to support communities during heat waves and disaster events, with local micro-grids and solar and battery backup to provide essential electricity.

Vermont and New York were the first states to enact superfund laws in 2024. More than 10 states introduced versions of these bills in 2025, and several —California, Connecticut, Massachusetts, Maryland, and New Jersey—are moving forward.

It’s time to protect our community from the impacts of climate disasters, to build resilience and adaptation measures, and to make sure we build a stronger economy for the 21st Century and a safe, healthy future.

Here’s how you can help! Please join us to share your thoughts, learn more, and find out how you can support this effort.
