A new government report highlights the potential for clean diesel to help meet the nation's growing energy and environmental demands, according to the Diesel Technology Forum. In their annual fuel economy rankings for the new model year released Oct. 29, the U.S. Department of Energy (DOE) and Environmental Protection Agency find that four of the top ten most fuel-efficient vehicles are diesel-powered. According to a recent study, advanced clean diesel engines already account for about one-third of all vehicles in Europe. In some European countries, diesel cars have over 50 percent of the total market share and upwards of 60 percent of new car sales. The report, "Demand for Diesels: The European Experience", is available for download on www.dieselforum.org. According to the DOE, gradually increasing Americans' use of currently available clean diesel technologies in cars, trucks, and SUVs to levels seen today in europe would reduce net crude oil imports by 350,000 barrels per day by 2020. The Diesel Technology Forum brings together the diesel industry, the broad diesel user community, civic and public interest leaders, government regulators, academics, scientists, the petroleum refining industry, and public health researchers, to encourage the exchange of information, ideas, scientific findings, and points-of-view related to current and future use of the new advanced clean diesel power technology.
