President Bush Announces Push To Encourage Use of Clean Diesel Cars in U.S. From remarks at the Small Business Administration's National Small Business Week Conference on April 27 President Bush: We're encouraging automakers to produce a new generation of modern, clean diesel cars and trucks. My administration has issued new rules that will remove more than 90 percent of the sulfur in diesel fuel by 2010. Clean diesel technology will allow consumers to travel much farther on each gallon of fuel, without the smoke and pollution of past diesel engines. We've proposed $2.5 billion over 10 years in tax credits that will encourage consumers to buy energy-efficient hybrid cars and trucks, and we need to expand these incentives to include clean diesel vehicles, as well.
