The accelerating climate crisis. Nature in peril. Unprecedented levels of pollution, and powerful special interests undermining basic protections. 

We’re up against immense threats, and there’s no time to waste. The Sierra Club works tirelessly to defend our environment and safeguard the future of our planet.

Change is powered by people, in communities all over the country -- and with 64 chapters in 50 states, we know we have what it takes to be effective and make a difference, for good. Support this vital work with your gift now.

And thank you!
