Feds Set Fuel Standards for Heavy-Duty Trucks and Buses

The National Highway Traffic Safety Administration (NHTSA) and U.S. Environmental Protection Agency (EPA) have established fuel-efficiency and carbon dioxide (CO2) standards for work trucks, buses and other medium- and heavy-duty vehicles. The first-time standards begin in model-year ’14 and cover a diverse range of vehicle types and uses. The vehicles are divided into three major categories: combination tractors (semi-trucks), heavy-duty pickups and vans and vocational vehicles (e.g. delivery trucks and transit buses). There are additional subcategories, which are intended to provide a flexible structure for achieving specific goals.

The fuel-efficiency standards will also be intended to reduce CO2 emissions, since carbon dioxide is a direct byproduct when carbon-based fuels are burned. In general, the standards are expected to achieve 10%–20% savings in fuel consumption by model-year ’18. Between 2014 and 2018, the reductions are projected to save 530 million barrels of oil and reduce CO2 emissions by 270 million metric tons.
