US environmental nonprofit founded in 1892, working on conservation, clean energy and climate through grassroots organising, legal advocacy and public education across 64 chapters.
Sierra Club is an American environmental organisation founded in 1892 by the conservationist John Muir. Its stated mission is to explore, enjoy and protect the planet, pursued through grassroots organising, legal advocacy, policy work and public education. It describes itself as the largest and most influential grassroots environmental organisation in the United States.
The organisation employs nearly 800 staff distributed nationwide, alongside thousands of volunteers and millions of members and supporters. Its structure comprises 64 local chapters covering all 50 states, Washington DC and Puerto Rico, giving staff and volunteers a presence in every state, including Florida. Work spans environmental advocacy, conservation, clean energy, public lands and wildlife protection, climate change and environmental justice.
Sierra Club's stated priorities include environmental justice for communities disproportionately affected by pollution and climate change, and equitable access to the outdoors. Roles tend to be mission-driven and organised around campaign, legal, policy, organising and public education functions rather than commercial products; the organisation does not sell consumer software or technology products.
