New Fuel Efficiency Standards for Trucks and Buses Formulated

New fuel efficiency standards for heavy vehicles targeting fiscal year as FY2025 formulated

March 29, 2019

Agency for Natural Resources and Energy

On March 29, 2019, the Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) revised the Standards for Determining Manufacturers and Other Companies of Energy Consumption Machines Concerning the Improvement of the Passenger Vehicles Performance in Terms of Fuel Consumption (Public Notice of the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism No. 2 of 2013) and another public notice and the ministries promulgated and enforced the revised standards. These public notices stipulate the new fuel efficiency standards for heavy vehicles, e.g., trucks and buses with a total weight of over 3.5 tons, and set FY2025 as the target fiscal year when manufacturers should achieve the defined fuel efficiency of such vehicles.

The new fuel efficiency standards require manufacturers to enhance the fuel efficiency by approximately 13.4% for trucks and other heavy vehicles and by approximately 14.3% for buses from the FY2015 fuel efficiency standards as a reference, respectively.

1. Background

Under the Act on the Rational Use of Energy, the ministries set the FY2015 Fuel Efficiency Standards for heavy vehicles, and all related companies have already met the standards. However, from the perspective of energy policy, the ministries consider it necessary to request companies to further enhance the energy efficiency of heavy vehicles.

To this end, the council of experts for discussing fuel efficiency standards (*1) jointly established by METI and MLIT held discussions on new fuel efficiency standards for heavy vehicles and, in December 2017, compiled the discussions results into new such standards in which FY2025 is set as the target fiscal year when manufacturers should achieve the defined fuel efficiencies for such vehicles.

Based on the compilation, METI and MLIT decided to revise, as necessary, the Standards for Determining Manufacturers and Other Companies of Energy Consumption Machines Concerning the Improvement of the Passenger Vehicles Performance in Terms of Fuel Consumption (Public Notice of the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism No. 2 of 2013) and the Standards for Determining Manufacturers and Other Companies of Energy Consumption Machines Concerning the Improvement of the Motor Truck Performance in Terms of Fuel Consumption (Public Notice of the Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1 of 2015).
