The Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) officially rolled out “Phase 2” greenhouse gas (GHG) and fuel efficiency rules this week aimed at four distinct commercial equipment types: Class 7 and 8 tractors, trailers, heavy-duty pickup trucks and vans, plus vocational vehicles. The “phase-in” period for the new rules stretches from model year 2021 thru model year 2027, by which time units within the four groups mentioned must be in full compliance.
