Korea: Light-Duty Vehicles

Korean diesel emission standards for passenger cars (<8 seats, GVW<2,500 kg) are listed in Table 1. Emission standards for light-duty diesel trucks (GVW<3,000 kg) are listed in Table 2.

Emissions are tested over the US FTP-75 cycle and expressed in g/km.

The Korean government has proposed that Euro 4 emission standards will apply to light-duty diesel vehicles effective January 2006 (and California ULEV standards for gasoline vehicles).
