South Korea has regulated emissions from motor vehicles for over two decades. Major updates to emissions standards occurred in 2000, 2002, 2006, 2009, and 2013. In 2009, South Korea adopted California’s Non Methane Organic Gases (NMOG) Fleet Average System (FAS) for gasoline-fueled vehicles. This FAS enables car manufacturers to have a range of models with different emissions levels. However, each carmaker’s fleet is required to meet a prescribed level of NMOG emissions on average. This average level of emissions is lowered over time. The timeline of average emissions standards is shown below in the technical standards section.
Diesel vehicle emissions standards follow the European precedent. As of 2002, emissions standards were equivalent with Euro 3. Emissions improvements have accelerated since then. In 2006, emissions for diesel vehicles were equivalent to Euro 4 until 2009, when the Euro 5 level was adopted. Since 2014, diesel vehicle emissions standards have been regulated under Euro 6.
Gasoline and gas-fueled vehicles are subject to California’s NMOG (Non-Methane Organic Gases) FAS (Fleet Average System). In the FAS, carmakers can choose one of four standards, each with different levels of emissions standards. The standards 1,2,3, and 4 are functionally equivalent to California’s LEV, ULEV, SULEV and ZEV1, respectively.
|Implementation Date||Standard||Tailpipe emissions (g/km)||Blow-by Gas Emissions (g/cycle)||Evaporative Gas Emissions (g/test)||Formaldehyde (g/km)||Test Cycle|
|1 Jan 2009||Standard 1||A||2.11||0.031||0.047||0||2||0.009||CVS-751|
|1 Jan 2013||Standard 1||A||2.11||0.031||0.047||0||1.2||0.009||CVS-75|
1 CVS-75 is identical to the FTP-75 (Federal Test Procedure 75) in the US.
Since 2014, diesel vehicles have been subject to Euro 6 regulations.
