EXPLANATORY MEMORANDUM
1.CONTEXT OF THE DELEGATED ACT
This Regulation amends Annex IV to Regulation (EU) 2024/1257 in order to take into account the latest technical progress and based on data collected when testing exhaust emissions of vehicles of categories N2, M3 and N3 and a report on the durability of heavy-duty vehicles submitted to the European Parliament and Council 1 .
The report proposes durability multipliers for Euro 7 heavy-duty vehicles, based on a technical report 2 analysing the durability of heavy-duty vehicles based on available data on emissions performance deterioration of Euro VI vehicles. The assessment considers emission information, first, for vehicles of categories N2 and N3 up to a maximum mass of 16 t and vehicles of category M3 up to a maximum mass of 7,5 t, and, second, for vehicles of categories N3 with a maximum mass higher than 16 t and M3 with a maximum mass higher than 7,5 t. It considers various pollutant emission components including NOx, which is the most critical emission component with respect to deterioration of emissions performance over the lifetime. Based on this information, the report proposes a durability multiplier of 1,2, which is in line with the durability multiplier for light-duty vehicles. Euro 7 heavy-duty vehicles are expected to perform better than Euro VI heavy-duty vehicles in terms of deterioration, as they are equipped with newer technology.
2.CONSULTATIONS PRIOR TO THE ADOPTION OF THE ACT
In the preparation of this act, the Commission carried out appropriate consultation with stakeholders and Member States in the Motor Vehicle Working Group meeting of 25 March 2026, where the draft was broadly supported. The Member States representatives endorsed the draft act during the Member States Expert Group - Motor Vehicles (MSEG-MV) meeting held on 28 April 2026.
In accordance with the Better Regulation rules, the delegated act was published on the "Have your say" portal for a four-week feedback period between 24 February 2026 and 24 March 2026. In total, 4 stakeholders provided feedback. The Commission carefully considered and took note of all the comments received.
3.LEGAL ELEMENTS OF THE DELEGATED ACT
The legal basis of this delegated act is Article 15(1)(f) of Regulation (EU) 2024/1257.
COMMISSION DELEGATED REGULATION (EU) …/...
of 9.6.2026
amending Regulation (EU) 2024/1257 of the European Parliament and of the Council as regards setting out durability multipliers for gaseous pollutants of heavy-duty vehicles of categories M3, N2 and N3
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EU) 2024/1257 of the European Parliament and of the Council of 24 April 2024 on type-approval of motor vehicles and engines and of systems, components and separate technical units intended for such vehicles, with respect to their emissions and battery durability (Euro 7), amending Regulation (EU) 2018/858 of the European Parliament and of the Council and repealing Regulations (EC) No 715/2007 and (EC) No 595/2009 of the European Parliament and of the Council, Commission Regulation (EU) No 582/2011, Commission Regulation (EU) 2017/1151, Commission Regulation (EU) 2017/2400 and Commission Implementing Regulation (EU) 2022/1362 3 , and in particular Article 15(1), point (f), thereof,
Whereas:
(1)Regulation (EU) 2024/1257 requires vehicles to respect the emission limits set out therein not only during the main lifetime, but also during the additional lifetime period that extends 25 % beyond the vehicle’s main lifetime. For that additional lifetime, durability multipliers are set out in Table 2 of Annex IV to Regulation (EU) 2024/1257 to account for the deterioration of emission reduction systems beyond the main lifetime period. In order to ensure legal clarity for vehicle manufacturers before the date of application of Regulation (EU) 2024/1257 as regards heavy-duty vehicles of categories M3, N2 and N3, it is necessary to set out durability multipliers for gaseous pollutants of heavy-duty vehicles of categories M3, N2 and N3 in Table 2 of Annex IV to Regulation (EU) 2024/1257.
(2)In accordance with Article 18(3) of Regulation (EU) 2024/1257, the Commission has prepared and submitted to the European Parliament and Council a report assessing the durability performance of heavy-duty vehicles with regard to emissions 4 .
