Sierra Club


Sierra Club
Climate Justice

The Sierra Club is the most enduring and influential grassroots environmental organization in the United States. We amplify the power of our 3.8 million members and supporters to defend everyone’s right to a healthy world.

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.
