During its April meeting in Italy, members of the World Semiconductor Council (WSC) agreed to reduce emissions of greenhouse gases called perfluorocompounds (PFCs), to at least 10 percent below 1995 levels by 2010.
The Council’s members produce over 90 percent of the world’s semiconductors and represent $125 billion in world sales for 1998. PFCs are the most potent and persistent of all greenhouse gases, having on average 10,000 times the global warming potential of carbon dioxide over 100 years, and atmospheric lifetimes ranging from 2,000 to 50,000 years. The chemicals play a critical role in semiconductor manufacturing and reducing them will be a formidable technical challenge.
