Further Fuel Efficiency Gains for Heavy-Duty Vehicles

In 2011, the National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) embraced standards to lower the greenhouse gas (GHG) emissions and enhance the fuel efficiency of heavy-duty vehicles in model years 2014–2018. These “Phase 1” standards will lessen vehicle fuel consumption by 6 to 24%, in model year 2018, depending on vehicle type. The two agencies are now in the process of developing the next phase of the program, which will be applicable to vehicles in years subsequent to model year 2018. An initial investigation of current and emerging technologies suggests that additional abatements of at least 26% are possible. This could result in further oil savings of 820,000 barrels each day by the year 2035.
