Phase 2 GHG standards to produce new generation of cleaner trucks

Posted On: 29-10-2015 By: David Thomas

The Environmental Protection Agency (EPA) have reported that the implementation of the proposed Phase 2 Greenhouse Gas (GHG) and Fuel Efficiency Standards will encourage the development of a new generation of cleaner trucks in North America.

Addressing the 8th Integer Emissions Summit & DEF Forum USA, Matt Spears, Center Director, Heavy-duty Diesel Standards at the EPA provided an update on the status of Phase 2 federal GHG and fuel efficiency proposal for medium and heavy-duty trucks

Spears reported that the proposed Phase 2 standards are performance based and that vehicle and engine manufacturers can choose their own technology pathway that works best for their customers which will ultimately encourage innovation in technologies.

Delivering the keynote presentation at the conference, Spears set the scene for why further emissions control regulation is required.  Spears reported that heavy-duty vehicles are responsible for 20% of energy use and GHG emissions in the transportation sector and stated that their model projects that heavy-duty emissions could overtake light-duty vehicle energy use by 2035-2040.

Looking back at the implementation of Phase 1 standards, Spears informed the audience that the market was accepting of the regulation with no evidence of a surge in pre-buying trucks ahead of implementation and that sales had actually increased after implementation.

Phase 2 is scheduled to be phased in from 2018 through to 2027 with standards for trailers commencing in 2018 and 2021 for other categories.  All standards would increase incrementally in 2024 and would be fully phased in by 2027. Spears emphasised the importance of a long lead time for Phase 2 implementation as this would allow OEMs the time to ensure the reliability and durability of the vehicles.

Spears addressed the key concerns of both vehicle manufacturers and end-users when summarising the projected cost for development of compliant trucks and the anticipated length of time for return on investment. The EPA’s projected average cost increase for model year 2027 vehicles is that tractor cost will increase by $11,700, trailers $1,200, vocational vehicles $3,400 and pick-ups and vans by $1,300.

Spears then detailed the length of time required for payback of the vehicle development through fuel savings with tractors and trailers covering the cost by the 2nd year, vocational vehicles by the 6th year and pick-ups and vans by the 3rd year.

The EPA and NHTSA aim to issue a joint Final Rulemaking for Phase 2 in the second quarter of 2016.
