The Environmental Protection Agency and National Highway Traffic Safety Administration recently finalized the Phase 2 GHG emissions standards for class 4-8 medium- and heavy-duty vehicles aimed at improving fuel efficiency while reducing vehicle emissions.

According to a statement by the EPA, the new vehicle and engine performance standards would cover model years 2021 to 2027, and apply to class 4-8 vehicles, which include semi-trucks, large pickup trucks and vans, and all sizes of buses and work trucks. The new regulations continue to build on the Phase 1 emissions standards currently in place for vehicle model years 2014 to 2018.

The regulations pose significant challenges for all fleet owners forecasting their future vehicle costs because the new requirements will increase the price of all affected vehicles, including gasoline and diesel vehicles. So, it’s important for fleet owners to perform their due diligence and research how their fleet costs will be affected by these new emission regulations, and what solutions can help them quickly recoup any increased vehicle costs.

Propane autogas, for example, offers a cost-effective solution for Class 4-7 vehicles while also providing a clean emissions profile.

Whether you’re talking diesel or gasoline, traditional fuels can’t compare to propane autogas when you consider the dollars invested per ton of emissions reduced. And propane autogas vehicles are well established in a variety of vehicle models today, including school buses, box trucks, large pickups, paratransit vans, and other work trucks.

Incorporating propane autogas into a fleet is simple, too. Installing on-site refueling is the least expensive of any fuel and primarily requires a level concrete pad supplied with electricity, a fuel storage tank, dispenser, and pump system. Refueling infrastructure can also grow with your fleet. Plus, new refueling technology can also figure into a fleet’s emissions-reduction plan. New propane autogas quick-connect nozzles provide a similar refueling experience when compared to gasoline and diesel and help reduce evaporative emissions in addition to those released at the tailpipe.

Propane autogas vehicles can be stored and serviced alongside gasoline and diesel vehicles if facilities are code compliant for traditional fuels, although it is recommended that fleet managers check with their local authorities having jurisdiction.

Taking the new emissions standards into consideration, propane autogas offers the lowest total cost-of-ownership when a fleet owner factors in the fuel’s lower price per gallon and reduced maintenance and repair costs.
