Commission Implementing Regulation (EU) 2025/1707 of 25 July 2025 laying down rules for the application of Regulation (EU) 2024/1257 of the European Parliament and of the Council as regards specific methods, requirements and tests, including compliance thresholds, for OBFCM devices and OBM systems, characteristics and performance of driver warning systems and inducement methods and methods to assess their operation, EVP format and data and methods of communication of EVP data of motor vehicles of categories M1 and N1 (Text with EEA relevance)

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

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

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

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

4. methods for in-vehicle display of environmental data about the vehicle type and the environmental performance of the individual vehicle;

5. 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:

1. M1 and N1;

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

The manufacturer shall ensure that the OBM systems perform the functions as laid down in Articles 4 to 10 by means of hardware and software installed in the vehicle for as long as the vehicle is in use.

The manufacturer shall ensure that OBM systems comply with the OBM data requirements as laid down in Annex I.

The manufacturer shall ensure that the excess exhaust emissions driver warning system (EEEDWS) performs the following functions:

1. assign the OBM monitoring status of NOx and particulate matter (PM) in accordance with Article 5;

2. provide driver warnings in accordance with Annex II as long as one or more of the exhaust emissions monitoring statuses is in ‘Error’ status;

3. if driver warnings referred to in point (b) are not acted upon within the period specified in Annex II, limit vehicle use through harmonised inducement methods described in that Annex until appropriate repairs are carried out.

The EEEDWS may assign the monitoring status for exhaust emissions other than NOx and PM using a generic OBM monitoring status parameter. Points (b) and (c) of paragraph 1 shall apply with regard to the generic OBM monitoring status parameter.

The manufacturer shall ensure that each OBM monitoring status is individually set. Each OBM monitoring status may be updated once after the end of each OBM trip as one of the following:

1. ‘Normal’ status, which shall indicate that the emissions control systems installed on the vehicle are judged to be functioning adequately and the OBM system has high confidence in the accuracy of OBM monitoring;

2. ‘Intermediate’ status, which shall indicate that the OBM system is unable to make a conclusive assessment of the status of the relevant emissions control systems or that an increased uncertainty in OBM monitoring values may exist;

3. ‘Error’ status, which shall indicate that faults or tampering that prevent adequate emissions control or monitoring and justify a repair have been identified.

As an indicative target when designing the OBM system, the manufacturer shall ensure that if the OBM determines that the vehicle may be in a state where its exhaust emissions as evaluated via a real-driving emissions (RDE) or other applicable in-service conformity test would be equal or higher than 2,5 times the applicable emission limit, the ‘Error’ status shall be activated.

The manufacturer may use any available data or engineering approach which allows the EEEDWS to determine the monitoring status of a pollutant, based on the expected exhaust emissions or performance of emissions control systems of a vehicle.
