Joint press release with the Ministry of Land, Infrastructure, Transport and Tourism
On June 3, 2019, the Council on Fuel Efficiency Standards for Passenger Vehicles (*1) held a meeting and presented the new target value of fuel efficiency standards for passenger vehicles and other targets.
The new value of such standards set FY2030 as the target fiscal year and, under the standards, manufacturers of passenger vehicles are required to improve the fuel efficiency thereof by 32.4% from the FY2016 sales performance.
Since its inauguration in May 2018, the council, a body jointly established by the Ministry of Economy, Trade and Industry (METI) and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), has been holding deliberations on new fuel standards for vehicles under the Act on the Rational Use of Energy (Act No. 49 of 1979). As part of these efforts, on June 3, 2019, the council held a meeting and presented a new target fiscal year, new value of fuel efficiency standards, and other goals.
In light of the report that the council will compile within a week or so, METI and MLIT will revise necessary laws and regulations and other rules.
1. Outline of the new fuel efficiency standards
- Target fiscal year: FY2030
- New value of fuel efficiency standards: 25.4km/L (*2; improvement by 32.4% from the FY2016 sales performance)
- Targets of the new standards: Gasoline vehicles, diesel vehicles, LPG vehicles, electric vehicles, and plug-in hybrid vehicles (underlined vehicles are newly targeted this time).
- How to calculate energy consumption efficiency rates (fuel efficiency values):
METI has adopted a “Well-to-Wheel (*3)” approach in assessing energy consumption efficiency rates. This approach takes into account energy consumption efficiencies of vehicles at the upstream side before supplying electricity, gasoline or other fuels to vehicles so that METI is able to compare the fuel efficiency value of electric vehicles and plug-in hybrid vehicles, which are newly targeted, and that of gasoline vehicles and other conventional vehicles.
2. Future schedule
In light of the report compiled by the council, METI and MLIT will revise necessary laws and regulations and other rules by around the end of FY2019.
3. Meeting materials
1. The council is a joint meeting of: 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; and the Subcommittee on Standards for Automobiles Energy Efficiency of the Automobiles Committee under the Land Traffic Committee of the Transport Policies Council.
2. The figure is the result of calculating weighted harmonic means of the value of fuel efficiency standards based on the data from the FY2016 sales performance.
3. The term “Well-to-Wheel” refers to an approach to assessing energy consumption of vehicles covering not only consumption of gasoline or other fuels in a vehicle fuel tank but also the manufacturing processes before supplying gasoline or other fuels to vehicles.
