Fight for the Planet

Sierra Club is working tirelessly to protect wildlife and wild places, ensure clean air and water for all, and fight the devastating effects of climate change.



Sierra Club is the most historic grassroots environmental organization in the country. For more than 130 years, we’ve gathered millions of activists and volunteers to fight for the places, people, and planet we all love.

382 Coal Plants Retired

We are addressing the climate crisis by stopping the expansion of fossil fuels and accelerating the transition to a clean energy economy.

439 Parks and Monuments Protected

We are at the forefront of the movement to preserve the beauty, natural environments, and recreational opportunities that public lands and waters provide.

64 Local Chapters

We partner with the most impacted communities to ensure all people benefit from clean air, fresh water, a stable climate and a direct connection to nature.

Join Our Movement

We can stop the climate crisis. But we must act now, together, to save our home, our world. The Sierra Club has people in 50 states across the country ready to mobilize. Will you join us?
