Automakers Support Proposed Sulfur Reductions in Diesel FuelsWASHINGTON, May 17 The following is a statement by Josephine S. Cooper, President, Alliance of Automobile Manufacturers, in response to the Environmental Protection Agency's (EPA) proposal to reduce sulfur levels in diesel fuel: "The Alliance applauds EPA's proposal to control sulfur in diesel fuel. While the Alliance believes even tighter limits and controls on additional parameters are needed, a 15 parts per million (ppm) cap on diesel sulfur levels will go a long way toward cleaning diesel fuel. "Control of sulfur levels in diesel fuel is critical if light-duty diesel vehicles are to meet the stringent Tier 2 emission standards that EPA finalized in December 1999. To achieve these standards with diesel engines will require the use of advanced emission control technologies, similar to those used on gasoline-fueled engines. Sulfur contaminates these devices and does not allow their use on diesel engines. The industry needs to keep open the possibility of using diesel engines to address societal needs in the coming years. "We support EPA's efforts and hope that EPA holds firm on its position and issues a final rule with stringent control of diesel fuel quality. Additionally, the Alliance joins other automobile and engine manufacturing associations from around the globe in recommending very clean fuels for its products. This recommendation is reflected in the recently revised (April 2000) World-Wide Fuel Charter, which calls for sulfur-free gasoline and diesel fuel for use with advanced technology and to help meet stringent emission standards. The Charter also recommends controlling other parameters, such as cetane and aromatics in diesel fuel. It was first established in 1998 to promote greater understanding of the fuel quality needs of motor vehicle technologies and to harmonize fuel quality world-wide in accordance with vehicle needs.
