Frack, Baby, Frack? What You Need to Know About Hydraulic Fracturing
In his 26 years as head of Environmental Defense Fund, Fred Krupp has overseen the growth of EDF from a small nonprofit with budget of $3 million into a recognized worldwide leader in the environmental movement. Under his direction, EDF’s full-time staff has increased from 50 to 350, membership has expanded from 40,000 to more than 500,000 and new offices have opened in Raleigh, Austin, Boston, Sacramento and Beijing, China.
Fred is widely recognized as the foremost champion of harnessing market forces for environmental ends, such as the market-based acid rain reduction plan in the 1990 Clean Air Act that The Economist hailed as “the greatest green success story of the past decade.” Today, this approach has become the leading model for solving the problem of global warming.
Fred broke new ground by engaging American companies to lessen their impact on the environment. Strategic partnerships with McDonald’s, FedEx, and DuPont, among others, have resulted in the elimination of millions of pounds of waste, the adoption of hybrid delivery vehicles, and an accord to reduce the environmental risks of nanotechnology.
