The Environment Ministry plans to submit a bill to the Diet to amend the current vehicle emissions law by imposing tougher controls on commercial users of diesel-powered vehicles, ministry sources said Monday.
The new measures to be proposed include tightening emission levels for particulate matter and compelling companies to reduce the number of diesel vehicles they run, the sources said.
The ministry expects to submit the amendment to the ordinary session of the Diet, following its endorsement by the government in early February, according to the sources. They added that the ministry aims to put the law into force during fiscal 2002.
