Agency for Natural Resources and Energy New Fuel Efficiency Standards for Heavy Vehicles Compiled

The Ministry of Economy, Trade and Industry(METI) hereby announces that a council for discussing regulation of vehicle fuel efficiencies,*1 which was jointly established by METI and the Ministry of Land, Infrastructure, Transport and Tourism(MLIT), compiled a draft proposal for new fuel efficiency standards for heavy vehicles, i.e., those with a gross weight exceeding 3.5 tons, such as trucks and buses.

Setting FY2025 as a target year, the draft proposal enhances such standards, increasing by approximately 13.4% for trucks and other heavy vehicles and by approximately 14.3% for buses from the existing fuel efficiency standards setting FY2015 as the reference year.

Since December 2016, the council has been holding discussions concerning new fuel efficiency standards for heavy vehicles under the Act on the Rational Use of Energy, and on December 12, 2017, it compiled the discussion results into the draft proposal.

In light of the draft proposal, METI and MLIT will call for public comments concerning the proposed standards, conduct other related efforts, and formulate new fuel efficiency standards for heavy vehicles.

Note:
*1:The council is a joint meeting of: The Subcommittee on Standards for Automobiles Energy Efficiency of the Automobiles Committee under the Land Traffic Committee of the Transport Policies Council; and the Working Group on Classification Standards for Automobiles of the Energy Efficiency and Conservation Subcommittee of the Committee on Energy Efficiency and Renewable Energy under the Advisory Committee for Natural Resources and Energy.

1. Outline of the draft proposal

  • Target fiscal year:FY2025
  • Proposed new fuel efficiency standards:*2
    • Trucks and other heavy vehicles:7.63 km/L (increased by approximately 13.4% from the existing standards)
    • Buses:6.52 km/L (increased by approximately 14.3% from the existing standards)
Note:
*2:The figures shown in the draft proposal, in which new fuel efficiency standards are compiled by gross-weight category of heavy vehicles, are the results of calculating weighted harmonic means based on the data on FY2014 sales performance by category in the related industries.
  • Targets of the new standards:Diesel vehicles

2. Future schedule

December 2017:
Call for public comments concerning the proposed fuel efficiency standards for heavy vehicles
April 2018:
Revision of related laws and regulations; formulation of new fuel efficiency standards for heavy vehicles

Release date

December 12, 2017
