The country’s trade and transport ministries will draft proposals for new fuel-efficiency standards for gasoline and diesel vehicles later this month, Yoshitaka Takeya, a Tokyo- based trade ministry official, reportedly said, according to Bloomberg.


The rules will apply to all manufacturers that compete in the country, he said.


The government will seek comments from the public before tougher fuel-efficiency standards, Takeya said.


The government plans to make automakers improve fuel efficiency of vehicles by about 20% by fiscal 2015 from the level in fiscal 2004, the Nihon Keizai newspaper said.


The standards, which will introduce 15 to 20 vehicle classifications from the current nine, would be the world’s toughest, the report said.
