Sierra Club is the largest and most influential grassroots environmental organization in the country. For more than 130 years, we’ve been working to promote clean energy, safeguard the health of our communities, protect wildlife, and preserve our remaining wild places through grassroots activism, public education, lobbying, and legal action.
We are stopping the expansion of oil and gas and accelerating the transition to a clean-energy economy
We are fighting for all people to benefit from clean air, fresh water, a safe climate, and connection to nature

We can stop the climate crisis. But we must act now, together, to save our home, our world. The Sierra Club has people in 50 states across the country ready to mobilize. Will you join us?
