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.
Clean energy technologies are driving a new era of job creation and American prosperity that works for everyone.
Local chapters are central to our grassroots mission and are the main drivers of Sierra Club’s values, priorities, and vision for the future.
