History
South Korea has regulated emissions from heavy-duty vehicles since February 1991. Diesel vehicle emissions standards follow the European precedent. As of 2002, emissions standards were equivalent with Euro III. Emissions improvements have accelerated since then. In 2006, emissions for diesel vehicles were equivalent to Euro IV until 2009, when the Euro V level was adopted. Since 2014, diesel emissions have been regulated under Euro VI limit values.
Technical Standards
Gasoline Vehicles
Emissions standards for heavy-duty gasoline vehicles are displayed below. The most recent standard was released in January 2013.
| Implementation Date | CO (g/km) | NOx (g/kWh) | HC | Test Cycle | ||||
|---|---|---|---|---|---|---|---|---|
| Tailpipe Emissions (g/km) | ||||||||
| Jan 1 20061 | 1.5 (0.4)2 | 3.5 | 0.46 (0.2) | ND-133 | ||||
| 4.0 | 3.5 | 0.55 | ETC | |||||
| Jan 1 2009 | 4.0 | 2.0 | 0.55 | ETC | ||||
| Jan 1 2013 | 4.0 | 0.4 | 0.14 | WHTC | ||||
| Notes: 1 Manufacturers can choose to comply based oh either the ND-13 or ETC test cycle. 2 Values in parentheses are for gas-fueled vehicles (compressed natural gas). 3 ND-13 cycle is identical to the ESC (European Stationary Cycle) in Europe. |

Diesel Vehicles
Emissions standards for diesel vehicles follow European precedent. Heavy-duty vehicles in Korea have been required to meet the Euro V emissions standards since September 2009. Since 2014, heavy-duty vehicles have been subject to Euro VI emissions standards.
| Implementation Date | CO | NOx | HC+NOx | PM | Smoke | PM# | Test Cycle1 |
