This report responds to a request from Senator Jeff Sessions for an analysis of the environmental and energy efficiency attributes of light-duty diesel vehicles.
Specifically, the inquiry asked for a comparison of the characteristics of diesel-fueled vehicles with those of similar gasoline-fueled, E85-fueled, and hybrid vehicles,
as well as a discussion of any technical, economic, regulatory, or other obstacles to increasing the use of diesel-fueled vehicles in the United States
