Every day, diesel engines—from those in heavy-duty trucks to school buses to delivery vehicles on city streets—pump noxious materials into the air. And until recent years, governmental clean-air regulation of diesel emissions has been minimal around the world. But now, the public health and environmental problems associated with these diesel emissions have become impossible to ignore. Corning, for many years, has been a leader in advanced ceramic substrates, found at the  heart of catalytic converters that help clean automobile emissions. Now it is positioned to enter  a period of robust growth as it works with diesel engine and vehicle manufacturers to help them comply with tightening diesel emissions rules. In the U.S., new standards call for a 90-percent reduction in particulate emissions and about  a 50-percent reduction of nitrogen oxides by 2007. So Corning engineers are now working closely with customers, designing, testing and delivering advanced emission-control solutions. Around the world, Corning is working to help customers meet new standards that require approximately an  80-percent reduction in particulate emissions and a 60-percent reduction of nitrogen oxides by 2008. These new emission requirements for the diesel vehicle market are estimated to create an approximately $1 billion worldwide market for substrates and filters by 2008, rivaling the current size of the gasoline-vehicle after-treatment market. Meeting this type of market challenge is what Corning does best. In many ways, we have been preparing for this opportunity for three decades. Building upon our capabilities and customer relationships in the market for catalytic converter substrates, we are extending our materials expertise and process understanding to carve out  a leadership position in the diesel arena as well. We are gearing up to meet this new market  opportunity with a new, state-of-the-art manufacturing facility in Erwin, New York, which began  production in early 2004. As with so many of our products, our technological know-how and legacy of innovation have created this strong growth potential. Our advanced ceramic substrates have long been the mainstay of catalytic converters used worldwide by leading vehicle manufacturers, and we have a deep understanding of the complex technology required for emission-control systems used by a wide variety of vehicle and engine manufacturers. We believe our ability to apply this technology to solve our customers’ difficult problems will continue to grow our leadership position in the world of environmental products. 1200 1000 800 600 400 200 0 02 03 04 05 06 07 08 Projected Market Revenue Diesel Opportunity Millions $ US 2004 Euro IV US 2007 Euro V
