Emissions from heavy duty vehicles (Euro VI): certification rules

Document or Iniciative

Regulation (EC) No 595/2009 of the European Parliament and of the Council of 18 June 2009 on type-approval of motor vehicles and engines with respect to emissions from heavy duty vehicles (Euro VI) and on access to vehicle repair and maintenance information and amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC (Text with EEA relevance).


This Regulation defines the legal framework for type-approval of motor vehicles, engines and replacement parts with respect to their emissions. It also establishes rules on:

  • in-service conformity of vehicles and engines;
  • durability of pollution control devices;
  • on-board diagnostic (OBD) systems and accessibility of information;
  • measurement of fuel consumption;
  • CO2 emissions.

This Regulation applies to motor vehicles of categories M1, M2, N1 and N2 (see Annex II of Directive 2007/46/EC).

Obligations of the manufacturers

Manufacturers must be able to demonstrate that all new vehicles, engines or spare parts sold, registered or put into service within the Community have been EC type-approved.

Manufacturers must also implement technical measures to guarantee effective limitation of tailpipe emissions.

This Regulation also establishes conditions for pollution control devices according to a mileage and life cycle specific to each vehicle category.

Requirements and tests

Manufacturers must equip their vehicles or engines with components that ensure compliance with the emission limits laid down in Annex I of this Regulation.

The European Commission lays down provisions to ensure compliance with emission limits – mainly measures concerning tailpipe emissions *, pollution control devices, reference fuels and the measurement of engine power.

Access to information

Vehicle manufacturers must guarantee independent operators * access to information on on-board diagnostic (OBD) * systems, and on diagnostic equipment, tools or software.

Manufacturers are also responsible for providing information on vehicle repairs and maintenance *. The final manufacturer shall be responsible for communicating information about the whole vehicle.

The information should be made available on the websites of manufacturers, or, if this is not feasible, in another appropriate format.


National authorities shall no longer grant Community or national type-approval for vehicles that do not comply with this Regulation as from 31 December 2012. They are also to prohibit the registration of new vehicles that do not comply with this Regulation as from 31 December 2013.

Financial incentives

Member States may grant financial incentives for the purchase of motor vehicles produced in series which comply with this Regulation until 31 December 2013. Retrofitting measures may also be considered either to adapt in-use motor vehicles or for scrapping.

The amount of the financial incentives shall be equal to the additional cost of the technical measures introduced to ensure compliance of the vehicle with emission limits.

This Regulation repeals Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC with effect from 31 December 2013.


The Sixth Community Environment Action Programme highlights the need to reduce air pollution. This Regulation contributes to the Union’s objectives in terms of air quality by establishing a system which constrains the automobile industry to limit the vehicle emissions that it produces.

Key terms of the Act
  • Tailpipe emissions: emissions of gaseous and particulate pollutants;
  • On-Board Diagnostic (OBD) system: a system on board a vehicle or connected to an engine which has the capability of detecting malfunctions, and, if applicable, of indicating their occurrence by means of an alert system, of identifying the likely area of malfunction by means of information stored in computer memory, and of communicating that information off-board;
  • Vehicle repair and maintenance information: all information required for diagnosis, servicing, inspection, periodic monitoring, repair, re-programming or re-initialising or the remote diagnostic support of the vehicle and which the manufacturers provide for their authorised dealers and repairers, including all subsequent amendments and supplements to such information. This information includes all information required for fitting parts or equipment onto vehicles;
  • Independent operator: undertakings other than authorised dealers and repairers which are directly or indirectly involved in the repair and maintenance of motor vehicles, in particular repairers, manufacturers or distributors of repair equipment, tools or spare parts, publishers of technical information, automobile clubs, roadside assistance operators, operators offering inspection and testing services, operators offering training for installers, manufacturers and repairers of equipment for alternative fuel vehicles.
