Fred Krupp (born 1954) is a prominent American environmental lawyer, advocate, and nonprofit leader who has served as president of the Environmental Defense Fund (EDF) since 1984, transforming it from a small nonprofit with a $3 million budget into a global organization with over $300 million in annual funding and more than 1,000 employees. Raised in Verona, New Jersey, he was influenced by his father's recycling business, which repurposed old rags into roofing material, sparking his early environmental interest. He earned a Bachelor of Science from Yale University (1975) and a Juris Doctor from the University of Michigan Law School (1978). After law school, he practiced in New Haven, Connecticut, at firms including Cooper, Whitney, Cochran & Krupp and Albis & Krupp, co-founding the Connecticut Fund for the Environment (now Save the Sound) and serving as its general counsel. Krupp also taught environmental law at both Yale University and the University of Michigan. Known for advocating market-based solutions and corporate engagement, his leadership at EDF has pioneered initiatives like the acid rain reduction program in the 1990 Clean Air Act Amendments, contributions to the Kyoto Protocol, partnerships with major corporations (e.g., McDonald's, Duke Energy, Walmart) to adopt sustainable practices, and involvement in the 2022 Inflation Reduction Act's climate provisions. He co-authored 'Earth: The Sequel' with Miriam Horn, focusing on innovative climate solutions. Krupp serves on influential boards including the Yale University Board of Trustees, the Yale School of the Environment Leadership Council, the H. John Heinz III Center for Science, Economics and the Environment, and the John F. Kennedy School of Government Environment Council, and has held advisory roles such as on the President's Advisory Committee on Trade Policy and Negotiations and the Secretary of Energy's Panel on Shale Gas (2011). He has been instrumental in EDF's MethaneSAT satellite project (announced 2018, launched 2024) to track methane emissions. Residing in Norwalk, Connecticut, he has received accolades including the 2015 William K. Reilly Environmental Leadership Award, the 1999 Keystone Leadership in Environment Award, and recognition as one of America's Best Leaders by U.S. News & World Report. His compensation as EDF president has been reported as over $1 million annually in recent years. His work emphasizes collaboration between environmentalists, businesses, and governments to address climate change and pollution.
