HD OTR Truck Fuel Savings Plans
In 2010, President Obama directed the EPA and the DOT?s National Highway Traffic Safety Administration (NHTSA) to develop joint greenhouse gas and fuel efficiency standards for heavy-duty trucks. The agencies met that directive in August 2011 by finalizing first-of-a-kind standards for new heavy-duty vehicles in model years 2014 through 2018. The majority of these trucks carry payloads of goods and equipment, in addition to passengers. To promote real world improvements in fuel efficiency, the heavy-duty standards require manufacturers? combination tractor fleets and vocational vehicle fleets to meet targets for gallons of fuel consumed ?and greenhouse gas emissions? per ton-mile, which account for how efficiently the vehicle perform the work they do. A simple mileage-based metric like miles-per-gallon would not account for the work these vehicles do. Manufacturers of pickup truck and van fleets must meet targets that incorporate payload and towing factors.
