The Sierra Club is one of the largest and most influential environmental organizations in the United States. Founded in 1892 by John Muir, it has played a key role in advocating for conservation, climate action, and environmental justice. The organization works to protect wild places, promote sustainable energy, and address climate change through policy advocacy and grassroots activism.
Headquartered in Oakland, California, the Sierra Club operates through local chapters across all 50 states, engaging in environmental campaigns, outdoor education, and legal efforts to safeguard natural resources. It has historically been involved in major conservation victories, including the establishment of national parks and opposition to fossil fuel expansion.
The Sierra Club also publishes Sierra Magazine, which covers environmental issues, sustainability efforts, and outdoor recreation. Over the years, the organization has expanded its focus to include social justice, recognizing the intersection between environmental and human rights issues.
