Commission Regulation (EU) 2026/361 of 19 February 2026 amending Regulation (EU) No 582/2011 as regards the emissions type-approval of heavy-duty vehicles with on-board fuel and energy consumption monitoring devices

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to 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 amending Regulation (EC) No 715/2007 and Directive 2007/46/EC and repealing Directives 80/1269/EEC, 2005/55/EC and 2005/78/EC [^ntr1-L_202600361EN.000101-E0001], and in particular Article 5(4), point (e), thereof,

Whereas:

• (1) While Commission Regulation (EU) No 582/2011 [^ntr2-L_202600361EN.000101-E0002] sets out requirements for the approval of heavy-duty vehicles with regard to emissions and Commission Implementing Regulation (EU) 2025/2161 [^ntr3-L_202600361EN.000101-E0003] sets out the technical requirements for determining the CO2 emissions and fuel consumption and on-board mass monitoring of heavy-duty vehicles on the road, the declaration of compliance of the on-board fuel and energy consumption monitoring (OBFCM) device and on-board mass monitoring system (OBMM) should be part of the type-approval system instituted by Regulation (EU) No 582/2011. It is therefore necessary to ensure a link between the emissions type-approval and compliance with the OBFCM requirements and to set out new emissions approval characters to allow for the identification of vehicles fitted with OBFCM devices.

• (2) While the on-board fuel consumption monitoring should be part of the engine type-approval system instituted by Regulation (EU) No 582/2011, the requirement regarding the determination of the vehicle total mass on-board the vehicle may be fulfilled either by the engine manufacturer or by the manufacturer responsible for the vehicle type-approval. Where the engine manufacturer does not provide for the determination of the vehicle total mass as set out in Implementing Regulation (EU) 2025/2161, the responsibility for the on-board mass monitoring should be on the manufacturer responsible for the installation of the engine into the vehicle.

• (3) As the fuel consumption values and CO2 emissions of heavy-duty vehicles resulting from the regulatory test procedures under Commission Regulation (EU) 2017/2400 [^ntr4-L_202600361EN.000101-E0004] is complemented by information recorded by the OBFCM device in accordance with Implementing Regulation (EU) 2025/2161 on the vehicles’ average real-world consumption when the vehicle is driven on the road, and as such information is essential for assessing that the regulatory procedures adequately reflect the average real-world CO2 emissions as well as the quantity of fuel and electric energy consumed, the accuracy of those OBFCM devices should be verified during on-road testing.

• (4) The necessary information on fuel consumption and emissions from the portable emissions measurement systems (PEMS) test procedure should be recorded to assess the accuracy of the OBFCM device as specified in Implementing Regulation (EU) 2025/2161.

• (5) Regulation (EU) No 582/2011 should therefore be amended accordingly.

• (6) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor Vehicles,

HAS ADOPTED THIS REGULATION:
