Democratic Rep. John Dingell, ranking member of the House Committee on Energy and Commerce, introduces a bill to provide tax incentives for buyers of diesel vehicles.
The bill also mandates that oil refiners produce and sell clean diesel fuel that meets government requirements for sulfur, lubricity, cetane and aromatics by January 2011. U.S. petroleum refiners have sued to stop a federal mandate to produce low-sulfur fuel starting in 2006.
