Permissible Limits of Motor Vehicle Exhaust Emissions

December 12, 2007

Based on the Report "Future Policy for Motor Vehicle Emission Reduction (eighth report)" issued by the Central Environment Council in April 2005, the Ministry of the Environment (MOE) will make a partial amendment to the "Permissible Limits of Motor Vehicle Exhaust Emission" (Environment Agency Announcement No. 1 of January 1974) under the Air Pollution Control Law. The amendment is primarily concerned with regulation strengthening of diesel motor vehicles. The announcement of the amendment will be made on December 13, 2007.

The principal details of the amendment are as follows:

1. In a bid to dramatically reduce particulate matter (PM) and nitrogen oxides (NOx), newly implemented emission regulations for diesel motor vehicles will come close to matching those for gasoline motor vehicles.
2. With concerns to PM emissions for gasoline motor vehicles, the same level of PM regulations will be implemented as for diesel motor vehicles.
Following this amendment, the Ministry of Land, Infrastructure and Transport will make partial amendments to the "Announcement that Prescribes Details of Safety Regulations for Road Vehicles" (Ministry of Land, Infrastructure and Transport Announcement No. 619 of July 15, 2002) under the Road Vehicles Act.
