The Goldman Environmental Prize
Grassroots environmental heroes too often go unrecognized. Yet their efforts to protect the world’s natural resources are increasingly critical to the well-being of the planet we all share. Thus, in 1990 San Francisco civic leaders and philanthropists Richard N. Goldman and his late wife, Rhoda H. Goldman (1924-1996) created the Goldman Environmental Prize. The Goldman Prize continues today with its original mission to annually honor grassroots environmental heroes from the six inhabited continental regions: Africa, Asia, Europe, Islands and Island Nations, North America, and South and Central America.

The Prize recognizes individuals for sustained and significant efforts to protect and enhance the natural environment, often at great personal risk. Each winner receives an award of $150,000, the largest award in the world for grassroots environmentalists. The Goldman Prize views “grassroots” leaders as those involved in local efforts, where positive change is created through community or citizen participation in the issues that affect them. Through recognizing these individual leaders, the Prize seeks to inspire other ordinary people to take extraordinary actions to protect the natural world.
