Sierra Club
The Sierra Club is an organization that believes in the power of people working together to make change happen. As the largest and most influential grassroots environmental organization in the US, for over 126 years, we've helped shape the way people can participate in local, state, and national advocacy and policy work, so that we can better protect the planet and each other. Our three million members and supporters - through the Sierra Club's resources, personal efforts, and collective action - have helped us make real change in advancing climate solutions, protecting lands, air, water, and wildlife, acting for justice, and getting people outdoors. We still have a lot more change to make, because so much more is possible. We work alongside other local and national groups because we are more powerful together. Join us in making change.
