Earth Island Institute

What Earth Island Institute does

Earth Island Institute is a 501(c)(3) nonprofit environmental organization founded in 1982 by David Brower, headquartered in Berkeley, California, and operating with 51-100 employees. Its primary function is acting as a fiscal sponsor to more than 75 environmental activist projects spanning conservation, wildlife protection, climate change, environmental justice, sustainable agriculture, and Indigenous community support. The organization delivers financial management, administration, training, and peer-learning services to these projects, allowing them to operate under Earth Island's tax-exempt status without establishing independent infrastructure.

Beyond fiscal sponsorship, Earth Island runs four direct programs: Earth Island Advocates, the in-house legal division conducting environmental litigation; New Leaders Initiative, a youth leadership program presenting the Brower Youth Awards (positioned as the premier youth environmental prize in North America); the Plastic Pollution Coalition, a project focused on advocacy and litigation against plastic pollution and false advertising; and the Earth Island Journal, an award-winning magazine publication. Recent legal actions include false advertising suits against bottled water companies (Danone, FIJI Water, PepsiCo, Core Water, Just Water), a sediment-removal challenge in Louisiana's Barataria Bay, an OSHA/EPA dispersant complaint, and a federal funding freeze lawsuit.

Revenue derives from individual donations, employer matching gifts, stock and vehicle donations, planned giving and bequests, fiscal sponsorship administrative fees, and limited grant funding (including a $138,000 USDA grant in December 2024). The organization is led by CEO Sumona Majumdar. It operates across global, North American, and Asia-Pacific geographies through its project network and partnerships with allied organizations such as Richman Law & Policy, ALERT, and Firefly Brigade.

Direct peers

• Tides Foundation: Tides Foundation is one of the largest fiscal sponsors in the U.S., providing financial management and administrative infrastructure to environmental, social justice, and progressive projects. It is the most direct functional peer to Earth Island Institute's Project Support Program.
• Rainforest Action Network: A U.S.-based environmental activism organization that campaigns on deforestation, climate, and corporate accountability. Comparable to Earth Island in advocacy tactics, campaign-driven funding model, and focus on corporate accountability.

Broad incumbents

• Greenpeace Fund: Greenpeace Fund is the U.S. fundraising entity supporting Greenpeace's global environmental campaigns. Comparable to Earth Island in environmental activism, donor-supported model, and global project network — though Greenpeace operates direct action campaigns that Earth Island does not.
• Natural Resources Defense Council (NRDC): NRDC is a major U.S. environmental advocacy organization using legal action, science, and policy advocacy. Comparable to Earth Island in litigation strategy (e.g., environmental protection lawsuits) and donor-supported model, but at significantly larger scale.
• Ocean Conservancy: Ocean Conservancy is a major U.S. marine conservation organization working on ocean health, plastics, and policy. Comparable to Earth Island's International Marine Mammal Project and plastic pollution litigation, though larger and more policy-focused.
• Environmental Defense Fund (EDF): EDF is one of the largest U.S. environmental nonprofits, combining science, economics, and law to drive environmental outcomes. It is a broad incumbent peer to Earth Island's legal advocacy and project-based environmental work.
• Sierra Club Foundation: The fiscal and philanthropic arm of the Sierra Club, supporting environmental programs through grants and donor-advised funds. It is a broad incumbent with comparable environmental mission and fiscal-sponsorship-adjacent activity, though its scope is tied to the Sierra Club ecosystem.
• World Wildlife Fund (WWF): WWF is one of the world's largest environmental organizations, operating across conservation, climate, and wildlife protection. Comparable to Earth Island's wildlife and conservation project network, but at vastly greater scale and global brand recognition.

Emerging players

• As You Sow: As You Sow is a nonprofit that uses shareholder advocacy and litigation to address corporate environmental and social responsibility. Closely comparable to Earth Island's Plastic Pollution Coalition litigation model against corporate deceptive marketing.
• 350.org: 350.org is a global grassroots climate movement organization focused on fossil fuel divestment and renewable energy. Comparable to Earth Island in climate-focused activism and donor-supported movement-building, but with a narrower thematic focus.
