Westport ready for new U.S. Phase 2 Emissions Standards

Westport ready for new U.S. Phase 2 Emissions Standards

Compliance costs may advantage natural gas sector, says Arthurs

Westport Fuel Systems Inc. says its technology is well positioned to meet the Phase 2 GHG emissions and fuel efficiency standards for medium- and heavy-duty vehicles imposed by the U.S. Environmental Protection Agency (EPA) and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) last week. The company already provides the next-generation natural gas engine and vehicle technology solutions to comply with the standards for greenhouse gas (GHG) emissions and fuel efficiency.

The EPA-NHTSA rules are the product of nearly two years of extensive consultation with industry partners and set a high standard for the freight sector.

“We commend the joint efforts of the EPA and NHTSA to develop an equitable Phase 2 Rule that will deliver significant environmental and economic benefits to 2027,” said Jim Arthurs, Executive Vice President, Medium- & Heavy-Duty Truck Strategies of Westport Fuel Systems.

“Freight transport by road is a vital part of the North American economy but also a major source of GHG emissions. The new EPA/NHTSA rules for GHG emissions and fuel efficiency from medium- and heavy-duty trucks will create a new competitive dynamic in the trucking industry. Westport Fuel Systems is well-positioned to deliver best-in-class engines and vehicles that meet increasingly stringent regulatory frameworks.”

Next generation natural gas engines and vehicles including Westport High Pressure Direct Injection 2.0 (Westport™ HPDI 2.0) and Enhanced Spark Ignition (Westport™ ESI) technologies comply with the new rule and offer significant GHG emission reduction benefits through the combination of low-carbon fuels and high-efficiency engines. In particular, Westport™ HPDI 2.0 has been proven to deliver diesel-like performance and fuel efficiency while providing a reduction in GHG emissions of 18-20% compared to current diesel engines.


The movement towards reduced GHG emissions and increased fuel efficiency is not restricted to the U.S. market. In an interview published in the July 2016 issue of lastauto omnibus magazine (a leading German transportation magazine), AVL’s representative stated that the European original equipment manufacturers will not be able to avoid implementing HPDI technology in order to fulfill GHG limit values. AVL believes this is a significant reason for vehicle manufacturers’ high interest in HPDI technology. Austrian company AVL List GmbH, one of the world’s leading powertrain engineering firms, entered into an agreement with Westport at the start of 2016 to give the two companies a major advantage in natural gas engine and vehicle development as the industry moves towards offering next-generation natural gas vehicles.

Westport Fuel Systems believes that the cost advantage of natural gas will increase. According to industry estimates, full compliance with the proposed standards will add several thousand dollars to the cost of vehicles running on conventional fuels.

“As GHG rules tighten, natural gas fueled vehicles may cost less than compliant conventional fuel vehicles, creating a compelling economic argument even without factoring in fuel savings. Fleet owners can focus on the environmental benefits of natural gas vehicles now and reap the economic benefits in the future,” said Arthurs.
