ACEEE’s latest report, Fuel Efficiency and Greenhouse Gas Emissions for Heavy-Duty Pickups and Vans: Phase 2, assesses the technologies available to reduce fuel consumption in these vehicles.
The report comes as the EPA and the US Department of Transportation are now working on Phase 2 of the fuel efficiency and GHG emissions standards for heavy-duty vehicles. The Phase 2 proposal is expected to be released later this month or in June.
Phase 1, adopted in 2011, will yield an average 12 percent reduction in fuel consumption for heavy-duty pickups and vans by 2018.
ACEEE says Phase 1 and Phase 2 standards together could reduce the fuel consumption of gasoline pickups and vans by 31 percent, and of diesel pickups and vans by 28 percent, relative to 2010 levels. Phase 2 could reduce fuel consumption by 23 percent and 15 percent beyond Phase 1 levels in gasoline and diesel vehicles, respectively.
