The Challenge
Today, there are serious challenges ahead: a warming climate, unprecedented levels of pollution, and powerful special interests undermining basic protections. There’s no time to waste in coming together for new solutions—which is why the Sierra Club is bringing people together to build the most powerful and effective environmental movement the world has ever seen.
Sierra Club's Statement on Reparations
The Sierra Club firmly supports reparations for Black people and believes it is impossible to create a healthy, safe, and sustainable future for all without acknowledging and materially addressing the past and present economic, cultural, psychological and spiritual impacts of racism.

How We Do It
We know actions speak louder than words. That’s why we’ve built a national community of volunteers, advocates, and grassroots activists who show up when and where it counts. Our supporters have the tools and resources to make themselves heard in nearly every district in every state across the country. From securing protection for 439 parks and monuments, to winning passage of the Clean Air and Endangered Species Acts, to putting over 281 coal plants on the path to replacement with clean energy, to securing the right of every kid in America to visit a national park, we have an unmatched record of success and impact.

A Diverse Coalition
We work with other partner organizations, nonprofits, and campaigns to build a diverse, inclusive movement that represents today’s American public. We know that environmental issues can’t be separated from social justice—because we all breathe the same air and share the same land. The Sierra Club also works with and supports companies that know strong values are a part of smart business.

Enjoying the Outdoors
And we help people enjoy the earth we’re protecting. Each year, Sierra Club volunteers lead over 15,000 trips annually, from extended trips across the world to afternoon hikes not far from home.

Our Roots
The Sierra Club's first members, including John Muir, were originally focused on the conservation of California's Sierra Nevada mountains. Since then, the Sierra Club has evolved into an organization that works to advance climate solutions and ensure everyone has access to clean air, clean water, and a healthy environment.
