About Us
The Sierra Club is America's oldest, largest and most influential grassroots environmental organization.


The Sierra Club's members are 750,000 of your friends and neighbors. Inspired by nature, we work together to protect our communities and the planet. The Club is America's oldest, largest, and most influential grassroots environmental organization.

The Sierra Club was founded in 1892 by John Muir and others, originally to protect the Sierra Nevada mountains of California. Click to learn more about Sierra Club history or view a timeline of the Club's accomplishments over the past century.

Through grassroots activism, public education, lobbying, and litigation, the national Sierra Club and its hundreds of local groups work to protect the health of our environment and preserve our remaining wild places.

The Sierra Club's Mission Statement

To explore, enjoy, and protect the wild places of the earth; to practice and promote the responsible use of the earth's ecosystems and resources; to educate and enlist humanity to protect and restore the quality of the natural and human environment; and to use all lawful means to carry out those objectives.

For the City of San Antonio and surrounding areas, the Alamo Group of the Sierra Club seeks sustainable practices, a clean environment and livable communities. We want our children to be able to breathe clean air and drink clean water. We act on local community issues that affect our lives and environment.

Sometimes we raise our voices by means of telephone calls, emails, and letters to our elected officials so they will act wisely on issues of importance.

Our club is a place where friends can have fun while making a difference. Join us on our worthy mission.
