New Fuel Efficiency Standards for Passenger Vehicles Finalized

Keywords: Government Policy / Systems Transportation / Mobility 

The Automotive Fuel Efficiency Standards Subcommittee (under the Automotive Traffic Subcommittee, the Land Traffic Committee and the Traffic Policy Making Council) and the Automotive Criteria Subcommittee (under the Energy Efficiency Standards Subcommittee, the Advisory Committee for Natural Resources and Energy), formed by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Ministry of Economy, Trade and Industry (METI), held a seventh joint meeting on October 20, 2011, to finalize new fuel efficiency standards for passenger vehicles under the Act on the Rational Use of Energy (Energy Conservation Act). The new standards aim to improve fuel efficiency by 24.1 percent from 16.3 kilometers per liter (km/L), the actual level in FY2009, to an estimated 20.3 km/L by FY2020.

After six joint meetings convened since June 2010 to compile an interim report, the ministries opened the proposals for public comments. The subcommittees then prepared a final draft of the standards in the seventh meeting after consideration of the collected comments. The standards adopted the top-runner approach, a system that identifies the most fuel efficient car in the market as a benchmark, for the prospect of technical development.

The standards are to be approved by the Automotive Traffic Subcommittee and the Energy Efficiency Standards Subcommittee, and this will be followed by amendments to the related laws around next spring.
