Revision of Fuel Efficiency Standards Planned for Heavy Vehicles

Keywords: Government Non-manufacturing industry Transportation / Mobility 

The Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure and Transport of Japan announced their final proposal for revising the fuel efficiency standards for heavy vehicles on November 10, 2005. They aim to amend the relevant legislation of the Law concerning the Rational Use of Energy in the spring of 2006, after further deliberation and approval.

In a bid to further promote global warming and energy saving measures, since September 2004 the ministries have held six deliberation meetings, compiled an interim report and invited public comments. In their seventh joint deliberation meeting, held on 10 November 2005, they finalized their proposal for revising the fuel efficiency standards for diesel-powered trucks and buses (with a capacity of 11 persons or more) whose gross weights are more than 3.5 tons.

If the revised standards are met, the mean fuel economy of heavy vehicles weighing more than 3.5 tons delivered in fiscal 2015 will be improved by 12 percent on average compared with those in fiscal 2002. By vehicle types, the figure for route buses is expected to improve from 4.51 to 5.01 km per liter, up 11.1 percent, for general-use buses from 6.19 to 6.98 km per liter, up 12.8 percent, and for motor trucks from 6.32 to 7.09 km per liter, up 12.2 percent.
