Policy description Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles (Phase 2).

Fuel efficiency standards for medium- and heavy-duty vehicles. There are four different categories: Combination Tractors, Trailers Pulled by Combination Tractors, Heavy-duty Pickup Trucks and Vans, Vocational Vehicles. The first phase is implemented for the period 2014-2018. The second phase is proposed (2021-2027) Targets Phase 1 (based on (ICCT, 2015a), see references for more details)

- 5.7 for heavy-duty vehicles, 7.3 for medium-duty vehicles

Phase 2 (based on (ICCT, 2015b), see references for more details)

- 6.1 miles per gallon by 2027 for medium trucks

- 4.6 miles per gallon by 2027 for heavy trucks
