Founded in 1892, the Sierra Club has evolved into the most effective grassroots environmental advocacy organization in the United States. Over 125 years in action, the Sierra Club started as a group tasked with protecting the Sierra Nevada. The club expanded to work on climate change, environmental justice, gender equity, green jobs and sustainable trade, food and agriculture as well as ecosystems protection and restoration.

Over the years, the club has been a major force in efforts to support sustainability and the environment. Most recently, the club has rallied to head off attempts by the Trump administration and others to dismantle years of environmental work, heritage and progress. Join us to celebrate all that the Sierra Club has done and will continue to do to protect the environment, health, safety and future of our people, land, water and air in the United States and around the world.
