Japan To Introduce Fuel Economy Standards For Trucks, Buses

Posted on September 29, 2005

The Japanese Ministry of Economy, Trade and Industry and the Ministry of Transport have decided to set the world's first fuel economy standards for large trucks and buses to curb Japan's carbon dioxide emissions, The newspaper Nihon Keizai Shimbun reported. The standards, which would be introduced this coming April, are aimed at improving fuel consumption of these vehicles by about 12% on average from their fiscal 2002 levels by fiscal 2015. The ministries plan to improve the fuel economy of trucks and buses that weigh more than 2.5 tons when fully loaded -- a vehicle class that has been exempt from such regulations.

Targets for improving fuel consumption will be set for 11 weight categories of trucks over 3.5 tons. A target for 2.5- to 3.5-ton vehicles will be set at a later date. Manufacturers failing to meet the targets will receive corrective action orders from the ministries. If they still fail to meet the standards, they and the models will be publicly named and fines levied. Pressure would be applied to end production of poorly performing models.
