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.

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.
