Fred Krupp, ’75 B.S., J.D.


Fred Krupp is president of the Environmental Defense Fund (EDF), one of the world’s leading environmental organizations.

Mr. Krupp has guided the EDF for more than three decades. His approach to advocacy — focused on ambitious, practical solutions to the world’s toughest environmental challenges — has been remarkably effective. Under his leadership, EDF has grown into one of the world’s most influential environmental organizations, increasing its members and supporters from 40,000 to 3 million and raising its annual budget from $3 million to more than $250 million. Originally focused only on U.S. policy, EDF now works internationally in 28 countries. Through this expansion, Mr. Krupp has focused global attention on the problem of climate-damaging methane pollution from oil-and-gas systems; expanded EDF's corporate partnerships to include FedEx, KKR, McDonald’s, Walmart, and more; successfully pushed major reforms to US chemical safety laws; and worked to empower fishing communities around the world to improve their own livelihoods while caring for the ocean. Before EDF, Krupp co-founded the Connecticut Fund for the Environment (now called Save the Sound), an advocacy group for environmental protection — the first organization of its kind in the state.

Mr. Krupp was named one of America’s Best Leaders by U.S. News and World Report and is a recipient of the 2015 William K. Reilly Environmental Leadership Award. At Yale, he has served as a member of the Yale School of Environment Leadership Council since 2001. Mr. Krupp earned his bachelor’s degree from Yale in 1975 and a J.D. from the University of Michigan Law School in 1978.

He was elected an alumni fellow in 2022.

Resides in Norwalk, Connecticut
