US EPA Phase II GHG Standards for HDVAdoptedReducing fleet level emission for Class 2b_3 vehicles by 16% between 2018 and 2025, with intermediate targets in 2021 (2.5%) and 2024(10%); for tractor trailers by 30% between 2018 and 2025, with intermediate targets in 2021 (16%) and 2024(24%); for vocational vehicles by 24% between 2018 and 2025, with intermediate targets in 2021 (12%) and 2024(20%). The test procedure is CAFÉ. This standard is also followed by Canada.2017NoYesYes
China Stage 3 HDV GHG StandardsAdoptedReducing fleet level emissions for tractors by 15.3%, for straight trucks by 13.8%, for dump trucks by 14.1%, for coach buses by 12.5% and for city buses by 15.9% in 2020 compared to 2015 (Stage 2 standards). For all vehicles, different values exist by precise weight classes, but these have been aggregated for ease of analysis. The test procedure is NEDC.2018YesYesYes
Japan New Fuel Efficiency Standards for Trucks and BusesAdoptedImproving fleet level fuel efficiency for transit buses from 6.73 km/l in 2015 to 7.63 km/l in 2025; for trucks from 5.7 km/l in 2025 to 6.52 km/l in 2025. The test procedure is JC08.2019YesYesYes
European Union HDV CO2 StandardsAdoptedReducing fleet level emissions for heavy trucks by 15% in 2025 and by 30% in 2030 compared to 2020. The test procedure is NEDC.2019NoNoYes
India BEE HDV Fuel Consumption StandardsAdoptedReducing fleet level emissions for heavy duty rigid trucks by 11%, for medium duty rigid trucks by 8%, for tractor trailers by 6.5%, and for buses by 16% in 2021 compared to 2018. For trucks, different values exist by precise weight classes, but these have been aggregated for ease of analysis. The test procedure is NEDC.2017YesYesYes
