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) 2022/1362OJ L, 2024/1257, 8.5.2024, ELI: http://data.europa.eu/eli/reg/2024/1257/oj. , and in particular Article 14(3), point (a) and Article 14(4), points (j), (k), (o), (s), (t), (u) and (v), thereof,

This Regulation lays down measures for the implementation of Regulation (EU) 2024/1257, with regard to the following:

(a) on-board monitoring (OBM) systems including their sensors and driver warning systems;

(b) on-board fuel and electric energy consumption monitoring (OBFCM) devices;

(c) the format and data and off-board communication methods for the environmental vehicle passport (EVP);

(d) methods for in-vehicle display of environmental data about the vehicle type and the environmental performance of the individual vehicle;

(e) methods and procedures to establish the absence of manipulation devices and manipulation strategies.

This Regulation applies to the motor vehicles belonging to the following vehicle categories:

(a) M1 and N1 ;

(b) N2 designated as Euro 7ext and Euro 7Gext in accordance with Article 5 of Regulation (EU) 2024/1257.

OJ L, 2024/1257, 8.5.2024, ELI: http://data.europa.eu/eli/reg/2024/1257/oj.

(1) Regulation (EU) 2024/1257 requires the Commission to set out procedures and testing methodologies, administrative provisions, procedures and methodologies for amending and extending emission type-approvals and data access, documentation requirements and templates for emission type-approval, conformity of production, in-service conformity and market surveillance for types of vehicles of categories M1 and N1 . By virtue of Article 5(2) and (3) of Regulation (EU) 2024/1257, those rules should apply also to N2 vehicles designated as Euro 7ext and Euro 7Gext in accordance with that Article.

(2) In particular, rules should be laid down regarding on-board monitoring (OBM) systems, excess exhaust emissions driver warning systems (EEEDWS), on-board fuel and electric energy consumption monitoring (OBFCM) devices, environmental vehicle passport (EVP) and in-vehicle display of environmental data and manipulation devices and manipulation strategies.

(3) The state of development of on-board sensors allows the continuous estimation of the emission rates of nitrogen oxides from light-duty vehicles. The emissions of other pollutants such as particulate matter can be reliably monitored by monitoring the integrity of particulate filters. It is therefore appropriate to set out requirements for OBM systems that include on-board sensors to assign a monitoring status to exhaust pollutants of interest to provide information to authorities about the functioning of emission control systems and the quality of exhaust emissions monitoring.

(4) For reasons of simplification and to achieve effective implementation of Regulation (EU) 2024/1257, it is appropriate to lay down rules specifying the general requirements for OBM and EEEDWS systems, OBFCM devices, EVP and in-vehicle display of environmental data laid down in that Regulation. Likewise, it is also appropriate to set out rules for the calculation of the OBM data parameters, for the on-board processing of OBM data, and for access to OBM data via the OBD port.

(5) To ensure that the measures used by OBM systems to induce repairs do not lead to road safety being endangered, it is appropriate that those systems use harmonised inducement methods.

(6) To ensure secure transmission of OBM data over the air, it is appropriate to allow manufacturers to use their own infrastructure and cybersecurity methods provided they comply with United Nations Regulation No 155UN Regulation No 155 – Uniform provisions concerning the approval of vehicles with regards to cybersecurity and cybersecurity management system (OJ L 82, 9.3.2021, p. 30 , ELI: http://data.europa.eu/eli/reg/2021/387/oj). In the case of a UN Regulation the series of amendments indicated reflects the version that has been published in the Official Journal of the European Union . Compliance with a series of amendments adopted after the particular series indicated shall be accepted as an alternative. .

(7) To ensure the submission of anonymous OBM data by vehicle manufacturers, it is appropriate to lay down requirements to that effect.

(8) To ensure that the anonymous OBM data transmitted to authorities is representative of the aggregate in-service emissions behaviour of vehicle types, it is appropriate to establish methods for the random sampling of OBM data to be transmitted over the air. Where the measures provided for in this Regulation entail the processing of personal data, that processing should be carried out in accordance with Regulations (EU) 2016/679Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation) (OJ L 119, 4.5.2016, p. 1 , ELI: http://data.europa.eu/eli/reg/2016/679/oj). and (EU) 2018/1725Regulation (EU) 2018/1725 of the European Parliament and of the Council of 23 October 2018 on the protection of natural persons with regard to the processing of personal data by the Union institutions, bodies, offices and agencies and on the free movement of such data, and repealing Regulation (EC) No 45/2001 and Decision No 1247/2002/EC (OJ L 295, 21.11.2018, p. 39 , ELI: http://data.europa.eu/eli/reg/2018/1725/oj). of the European Parliament and of the Council, as well as the relevant national law in accordance with those Regulations.

(9) To ensure effective implementation of OBM systems over the lifetime of vehicles placed on the market, specific requirements should be set out to address in-service conformity testing and market surveillance of such systems.

(10) Vehicles for which the OBM system has identified a potential malfunction or tampering should be considered to be in the process of being repaired. It is therefore appropriate to exclude such vehicles from certain aspects of in-service conformity testing.

(11) Requirements for OBM systems should adhere to the principle of technology neutrality where possible. It is therefore appropriate to lay down rules for the processing and transmission of OBM data which are broadly applicable to all powertrains, while recognising that certain OBM parameters may not be relevant to certain powertrains, for example, battery durability parameters for vehicles not equipped with a traction battery, or exhaust emission parameters for vehicles without an engine, and should not be processed in such cases.

(12) Certain OBM parameters that characterise the exhaust emissions of vehicles are also relevant to OBFCM devices. It is therefore appropriate to identify such parameters and to ensure they are transmitted by the vehicles using the data transmission methods envisaged for OBM systems, with a view to minimise the duplication of data that are transmitted over the air by OBM systems and OBFCM devices.

(13) The methods and administrative arrangements for the transmission of anonymous OBM data from manufacturers to authorities should be set out at a later stage of implementation. It is therefore appropriate to refer to these by using generic terms such as authority server that do not prejudge the solutions that will be implemented.

(14) It is appropriate to specify the technical requirements so that vehicles make available information on their environmental performance through the EVP and, where appropriate, also by displaying relevant information inside the vehicle. The EVP should use technical solutions that ensure the interoperability with other digital product passports. To ensure the availability of information over time, EVP data should be made available by means of a QR code. The QR code acting as a data carrier for EVP data should respect the guidelines of ISO/IEC Standard 18004:2024.

(15) A robust framework for the prohibition of manipulation devices and manipulation strategies should ensure that the emissions behaviour of vehicles is not altered between compliance testing and real-world driving, and that data on sensors, fuel or electric energy consumption, electric range, and battery durability remains accurate and reliable. It is therefore appropriate to set out general and technical requirements, as well as specific documentation requirements, to implement the prohibition of manipulation devices and manipulation strategies, and to clarify the roles and responsibilities of manufacturers, type-approval authorities, market surveillance authorities, the Commission and recognised third parties.

(16) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee – Motor vehicles (TCMV),
