Summary of worldwide diesel emission standards is presented in cooperation withDiesel Progress Magazine.

  • Euro I standards were introduced in 1992, followed by the introduction of Euro II regulations in 1996. These standards applied to both truck engines and urban buses, the urban bus standards, however, were voluntary.
  • In 1999, the EU adopted Directive 1999/96/EC, which introduced Euro III standards (2000), as well as Euro IV/V standards (2005/2008). This rule also set voluntary, stricter emission limits for extra low emission vehicles, known as “enhanced environmentally friendly vehicles” or EEVs.
  • In 2001, the European Commission adopted Directive 2001/27/EC which prohibits the use of emission “defeat devices” and “irrational” emission control strategies, which would be reducing the efficiency of emission control systems when vehicles operate under normal driving conditions to levels below those determined during the emission testing procedure.
  • Directive 2005/55/EC adopted by the EU Parliament in 2005 introduced durability and OBD requirements, as well as re-stated the emission limits for Euro IV and Euro V which were originally published in 1999/96/EC. In a “split-level” regulatory approach, the technical requirements pertaining to durability and OBD—including provisions for emission systems that use consumable reagents—have been described by the Commission inDirective 2005/78/EC.
  • Euro VI emission standards were introduced by Regulation 595/2009published on 18 July 2009 (with a Corrigenda of 31 July 2009). The new emission limits, comparable in stringency to the US 2010 standards,become effective from 2013 (new type approvals) and 2014 (all registrations). In the “split-level” approach, a number of technical details will be specified in the implementing regulation (‘comitology’) which should be adopted by the end of 2010.
