This study was undertaken at the request of the Committee on Science, U.S. House of Representatives. The Committee asked the Energy Information Administration (EIA) to provide an analysis of the Final Rulemaking on Heavy-Duty Engine and Vehicle Standards
and Highway Diesel Fuel Sulfur Control Requirements, which was signed by President Clinton in December 2000.
