Du Pont Corporation • The single largest corporate polluter in the United States • In 1989, Du Pont and its subsidiaries reported discharging more than 348 million pounds of pollutants to land, air, and water. • 1989 was 10 million pounds greater than 1987
Du Pont Comparison: 1989 • More pollution than Allied-Signal, Ford Motor Company, and Union Carbide combined. • 14 times greater than Dow Chemical • 20 times greater than Chrysler • 30 times greater than Mobil
Conservative Estimates • Du Pont’s “Toxic Release Inventory” (TRI) is self-reported and covers only 321 out of approximately 60,000 chemicals. • TRI does not refer to mines, tank farms, oil and gas drilling, or incinerators
Du Pont’s Response • In 1990, Du Pont’s chief executive, Ed Woolard, said that the company would voluntarily reduce its air emissions by 60% by 1993, using 1987 as the base year. • Other reductions were also announced.
Du Pont’s Actions • Change in waste disposal strategies. • Du Pont shifted from visible waste disposal strategies to less visible methods. • Greater use of deep-well injection and high-temperature incineration. • Partial treatment only for other waste flows.
Du Pont’s Deep-Well Methods • 1989: 254.9 million pounds • More waste than most Fortune 500 companies produce from all sources in a year. • 39 Class 1 hazardous waste wells, ranging from 2,500 to 10,000 feet deep. • High levels of toxicity.
Uncertainty • Congressional Office of Technology Assessment knows where the wells are located. • But no one knows where the wastes will end up. • Many reports of deep-well leaks into drinking water, and blowouts.
Chlorofluorocarbons (CFCs) • Du Pont chemist, Thomas Midgely Jr. discovered CFCs in 1928. • Marketing began in 1931 under trade name of Freon. • Many varied uses for CFCs. • Du Pont held a near monopoly of market for more than 40 years for many CFC lines.
CFCs and the Ozone Problem • 1974 discovery that chlorine in CFCs caused destruction of ozone. • By 1978, aerosol sprays were banned in U.S. Demand for CFCs dropped by 50%. • Du Pont fought the ban.
New Research • By 1979, four years of research led to two alternatives to CFC, both better, but with problems. • In 1981, all research stops when Ronald Reagan wins presidency.
The Ozone “Hole” • 1985, a team of British scientists discover an ozone hole over Antarctica. • 1986, research at Du Pont for CFC alternatives resumes. • 1989, Du Pont announces unilateral withdrawal of CFC production.
CFC /Alternatives • HCFCs - partially halogenated CFCs, still have chlorine • HFCs - non-chlorine, with hydrofluorocarbons
Montreal Protocol Acceptance • Non-binding resolution to phase out HFCs and HCFCs by 2040. • U.S. Clean Air Act calls for phase-out of HCFCs by 2030. • Du Pont’s lobbyists win argument to guarantee minimum life of 20 years for new chemicals. New monopoly established.
