It has been nearly four years since the U.S. Environmental Protection Agency (EPA) and the National Highway and Traffic Safety Administration (NHTSA) finalized a second round of standards (known as Phase 2) for medium- and heavy-duty trucks and trailers to both reduce greenhouse gas (GHG) emissions and improve fuel efficiency. The standards apply to “new” engines and Class 2b-8 trucks, as well as designated “new” trailers.
Targets for engines and trucks must be achieved in model years 2021, 2024, and 2027 and the deadlines for compliance are fast approaching. While fleet acceptance and purchases of fuel-efficient technologies under Phase 2 will directly determine the overall success of the rule, compliance is the responsibility of engine, truck and trailer manufacturers.
The rule does not mandate specific technologies but rather sets carbon and fuel efficiency performance standards for manufacturers to meet using numerous technology choices.
Attend this session and learn how engine and tractor manufacturers intend to comply with Phase 2 regulations and how their decisions will impact your maintenance operation. We’ll explore how engine and aftertreatment management is likely to change and what decisions fleets will have to make as they make their model year 2021 and 2024 buying choices.
