COMMISSION IMPLEMENTING REGULATION (EU) 2025/35

of 13 January 2025

implementing Regulation (EU) 2019/1242 of the European Parliament and of the Council by determining the procedures for the in-service verification of the CO

2 emissions of heavy-duty vehicles

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

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

Having regard to Regulation (EU) 2019/1242 of the European Parliament and of the Council of 20 June 2019 setting CO

emission performance standards for new heavy-duty vehicles, and amending Regulations (EC) No 595/2009 and (EU) 2018/956 of the European Parliament and of the Council and Council Directive 96/53/EC (1), and in particular Article 9(3) and Article 13(4), first subparagraph, thereof,

Whereas:

(1) Article 9 of Regulation (EU) 2019/1242 requires type-approval authorities to report to the Commission any deviations in the CO

emission values of heavy-duty vehicles in service as compared to the values that are indicated in the certificates of conformity or in the customer information file accompanying those vehicles as a result of verifications performed in accordance with Article 13 of that Regulation.

(2) Under Article 13 of Regulation (EU) 2019/1242, type-approval authorities which granted manufacturers a licence to operate a simulation tool under Regulation (EC) No 595/2009 of the European Parliament and of the Council (2) and Commission Regulation (EU) 2017/2400 (3) (‘granting approval authorities’) are to verify for those manufacturers, on the basis of appropriate and representative vehicle samples, that the CO

emission and fuel consumption values recorded in the customer information files correspond to the CO

emissions from, and fuel consumption of, heavy-duty vehicles in-service as determined in accordance with Regulation (EC) No 595/2009 and its implementing measures, as well as the presence of any strategies on board or relating to the sampled vehicles that artificially improve the vehicles’ performance in the tests performed or in the calculations made for the purpose of certifying the CO

emissions and fuel consumption (‘in-service verification’).

(3) Commission Delegated Regulation (EU) 2024/1127 (4) sets out the guiding principles and criteria for defining the procedures for performing the in-service verification.

(4) This Regulation sets out detailed procedures for the in-service verification, in line with those guiding principles and criteria.

(5) In order to target for in-service verification those families with vehicles or tyres presenting the highest risk for a deviation in the CO

emission and fuel consumption values from the specific CO

emission and fuel consumption values recorded in the customer information file, the granting approval authority should select families on the basis of a risk assessment to be performed by the Commission.

(6) In the case of tyres, as an in-service verification tyre family can be used by multiple vehicle manufacturers, it is appropriate to limit the testing of tyres from an in-service verification tyre family to one granting approval authority within each in-service verification reporting period, in order to simplify the process and reduce the administrative burden. Similarly, a component defining a verification testing procedure family can be used by multiple vehicle manufacturers. Therefore, it is appropriate to limit also the testing of vehicles from a verification testing procedure family to one granting approval authority within each in-service verification reporting period.

(7) In order to ensure that the in-service verification is representative, the granting approval authorities should select a minimum number of families to be tested, based on the calculation, for each manufacturer, of the total number of vehicles, for which the CO

emissions and fuel consumption have been determined under Article 9 of Regulation (EU) 2017/2400 (‘total number of vehicles under Article 9 of Regulation (EU) 2017/2400’), and in the case of trailers, based on the calculation, for each trailer manufacturer, of the total number of trailers, for which the CO

emissions and fuel consumption have been determined under Article 8 of Commission Implementing Regulation (EU) 2022/1362 (5) (‘total number of trailers under Article 8 of Implementing Regulation (EU) 2022/1362’). In the case of trailers, only in-service verification (‘ISV’) tyre families should be selected for in-service verification, as the verification testing procedure and air drag tests are not yet defined for trailers.

(8) The CO

emission and fuel consumption values recorded in the customer information file is to be determined by a simulation tool, based on certification testing of relevant vehicle components. Conformity of the simulation tool operation is to be verified by a verification testing procedure at vehicle level in accordance with Regulation (EU) 2017/2400. It is appropriate to require that the vehicles selected for the in-service verification tests are in a similar condition as those tested during the verification testing procedure, in particular by setting requirements for their maximum mileage and age.

(9) Only new tyres are appropriate for a tyre rolling resistance coefficient test carried out within an in-service verification, as testing used tyres would result, due to their wear, in a significantly lower rolling resistance coefficient. The selection of tyres for in-service verification tests should be independent from the selection of vehicles for in-service verification tests.

(10) In order to allow the granting approval authority to come to a conclusion for all vehicles concerned, on the basis of the test results for the vehicles sampled, a statistical evaluation method based on sequential sampling has been established.

(11) In case a verification testing procedure family fails the statistical evaluation of the test results as set out in Annex I, the CO

emission values of all vehicles concerned should be corrected, as passing that verification testing procedure is a prerequisite for maintaining the emissions type approval. In addition, it is appropriate that the granting approval authority investigates if there is sufficient evidence that a specific component is the cause of failing the statistical evaluation, in which case more vehicles could be concerned.

(12) In order to verify that the CO

emission and fuel consumption values recorded in the customer information file correspond to those values of heavy-duty vehicles in service, the test conditions and test results should be specified in accordance with Regulation (EC) No 595/2009 and its implementing measures.

(13) For air drag test conditions, to ensure that the possible variations in test conditions between in-service verification tests are reduced as much as possible, it is appropriate to apply the air drag test conditions in accordance with Regulation (EU) 2017/2400 in the latest version in force, as these conditions have been narrowed down compared to the conditions applicable at the time of the certification.

(14) In accordance with Regulation (EU) 2017/2400, manufacturers are allowed to determine air drag values based on a computational fluid dynamics (‘CFD’) simulation method. Therefore, it is appropriate to introduce a specific test to verify the specific validation of that simulation method as part of the in-service verification tests to verify the air drag values.

(15) In order to detect an artificial strategy, which operates only during the verification tests and not during normal operation in-service, it is crucial that the specific testing conditions are not known beforehand. Therefore, the conditions for the dedicated artificial strategy tests should be determined on a case-by-case basis by the granting approval authority.

(16) Given that the exact nature of artificial strategies cannot be known beforehand, the analysis and evaluation of the artificial strategy test results should be done by the granting approval authority based on a comparison of results found under different test conditions.

(17) In order to document the test results and provide for their further analysis, the granting approval authority should make the test report available to the Commission and the manufacturer concerned. In order to support the risk assessment performed by the Commission, it is appropriate to require that the test data is also submitted to the Commission, using a dedicated platform.

(18) If a deviation in the CO

emission values has been found, the manufacturer concerned should be given the opportunity to react to the findings of the granting approval authority within an appropriate time limit to avoid an undue lengthening of the in-service verification process. It should, however, be possible to extend the time limit in order to properly assess the technical documents provided.

(19) Where a lack of correspondence between CO

emission values of the in-service verification and the values recorded in the customer information files, or the presence of any strategies artificially improving those vehicles’ performance is found as a result of the performance of in-service verification tests, the specific CO

emissions of all vehicles concerned should be corrected, given that the test vehicles are deemed to be representative of all vehicles concerned.

(20) In order to take the deviations into account for the purpose of calculating and correcting the average specific CO

emissions of a manufacturer, it is appropriate that the Commission determines the size of the deviation in the CO

emission values and which vehicles are concerned.

(21) A correction of the average specific CO

emissions of a manufacturer should be applied from the reporting period of the year 2025, as that is the first reporting period for which CO

emissions reduction targets are applied in accordance with Regulation (EU) 2019/1242.

(22) The measures provided for in this Regulation are in accordance with the opinion of the Climate Change Committee,

Statistical evaluation of mass test results and calculation of the size of the deviation

1. The granting approval authority shall evaluate the mass test results of individual test vehicles obtained in accordance with Article 16 to establish whether or not there is a deviation in the CO

emission values of all vehicles of that manufacturer, by using the method set out in Annex II.

2. In case the vehicle manufacturer fails the statistical evaluation as set out in Annex II, the granting approval authority shall determine the size of the mass deviation as the average value for mass

ratio

(average

ratio

) as defined in Annex II for mass test results.

Article 18

Test conditions for artificial strategies tests

The granting approval authority shall verify the presence of artificial strategies in the test vehicle selected in accordance with Article 5 of this Regulation by means of at least the following tests:

(a) a VTP test;

(b) a VTP test with the test conditions set outside the boundaries set out in Annex Xa to Regulation (EU) 2017/2400, or any other test for which the testing conditions do not lead to a significant change in the physical response of the vehicle or any of its sub-systems.

Article 19

Evaluation of artificial strategies test results and calculation of the size of the deviation

1. The granting approval authority shall evaluate the results of the tests performed in accordance with Article 18 of this Regulation to assess the risk of artificial strategies being present in the test vehicle, by comparing the C

VTP, ratio

determined in accordance with point 7.2.2 of Annex Xa to Regulation (EU) 2017/2400 and obtained in the test referred to in Article 18, point (b), of this Regulation, with the C

VTP, ratio

obtained in the test referred to in Article 18, point (a), of this Regulation. In addition, the granting approval authority shall evaluate any other relevant tests performed on the vehicle concerned.

2. The granting approval authority shall describe in the test report the criteria used for the evaluation carried out in accordance with paragraph 1. For that purpose, artificial strategies shall be understood as any software, control logic, hardware or component on board or relating to the vehicle, which reduces the vehicle’s CO

emission or fuel consumption values in the tests performed for the purpose of CO

emissions certification, but which does not operate consistently when the vehicle is in-service, taking into account the difference between those test conditions and the in-service conditions, unless that inconsistent operation results from requirements laid down in Union law or is justified by the necessity to protect the vehicle against immediate damage or to ensure the safe operation of the vehicle.

3. If, based on the assessment carried out in accordance with paragraph 1, the granting approval authority concludes that the risk that artificial strategies are present in the test vehicle is high, it shall specify and perform a specific test programme in addition to the tests performed in accordance with Article 18, to identify the presence or absence of an artificial strategy. On the request of the granting approval authority, the manufacturer shall provide all relevant related software code to identify the presence or absence of an artificial strategy.

4. If the granting approval authority concludes that artificial strategies are present, it shall determine the vehicles concerned and the size of the deviation in the CO

emission values by comparing the CO

emission value with and without artificial strategies. If the size of that deviation cannot be determined based on the tests performed in accordance with Article 18 and, if applicable, paragraph 3 of this Article, the size of the deviation in the CO

emission values shall be 10 % of the CO

emission value of the reference CO

emissions of the vehicle sub-group.

Article 20

Test report

1. The granting approval authority shall include in the test reports referred to in Article 5(1) of Delegated Regulation (EU) 2024/1127 at least the following information for each family tested:

(e) the statistical evaluation of the test results;

(f) if applicable, the calculation of the size of the deviation;

(g) in case of an artificial strategies test: the criteria used for evaluating the test results.

2. Within 20 working days of finishing the tests, the granting approval authority shall make the test report available to the manufacturer of the vehicles or tyres concerned and upload it in an encrypted format to a dedicated Commission server, together with the following data for each of the individual test vehicles or tyres:

(a) for each VTP test performed, the data specified in point (1) of Annex IV to this Regulation;

(b) for each air drag test performed, the data specified in point (2) of Annex IV to this Regulation;

(c) for each CFD method air drag test performed, the data and calculations specified in Appendix 10 to Annex VIII to Regulation (EU) 2017/2400;

(d) for each tyre rolling resistance coefficient test performed, the data specified in point (3) of Annex IV to this Regulation;

(e) for each mass test performed, the data specified in point (4) of Annex IV to this Regulation.

The data and parameters specified in points (a) to (e) shall not be published.

Where all data have been correctly uploaded for all tested vehicles or tyres of a family, a receipt shall be sent from the Commission server to the uploading entity.

Article 21

Conclusions of the granting approval authority

1. If the results of the in-service verification show that there is no deviation in the CO

emission values, the granting approval authority shall come to the conclusion that there is no lack of correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file, and include that conclusion in the test report.

2. If the results of the in-service verification show that there is a deviation in the CO

emission values, the manufacturer may contest the results within 20 working days after receiving the test report, by providing evidence demonstrating the correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file. The manufacturer may request an extension of 20 working days to provide that evidence.

In the absence of a reaction, the manufacturer shall be considered to have accepted the results of the in-service verification.

3. Taking into account the evidence provided by the manufacturer under paragraph 2, the granting approval authority shall come to a conclusion on whether or not the in-service verification has identified a lack of correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file, or the presence of artificial strategies.

The granting approval authority shall transmit its conclusion to the manufacturer concerned and to the Commission at the latest 40 working days, or in case of extension in accordance with paragraph 2, at the latest 80 working days, after having sent the test report to the manufacturer under paragraph 2.

4. The granting approval authority’s conclusion referred to in paragraph 3 shall, as a minimum, include the following:

(a) where the granting approval authority finds that there is no lack of correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file, or cannot establish the presence of artificial strategies:

(i) the type of test and the family concerned;

(ii) the grounds for its finding that the deviation in CO

emission values found as a result of the in-service verification does not lead to a lack of correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file;

(b) where the granting approval authority establishes a lack of correspondence between the CO

emission values of the in-service verification and the values recorded in the customer information file, or the presence of artificial strategies:

(i) the type of test and the family concerned;

(ii) the size of the deviation, as reported in accordance with Article 20(1), point (e);

(iii) where applicable, the artificial strategies identified.

5. Before 30 September of each calendar year, the granting approval authority shall publish an overview of the in-service verifications performed in the previous reporting period and its conclusions issued in that reporting period, as referred to in paragraphs 1 and 3, using the format set out in Annex V. For in-service verification tests for which no conclusion is established before the publication of the overview, the conclusion shall be included in the next annual overview.

Article 22

Size of the deviation in CO

2 emission values and determination of the vehicles concerned

Where the granting approval authority has issued a conclusion as referred to in Article 21(4), point (b), the Commission shall determine the size of the deviation in the CO

emission values and all vehicles that are concerned, as follows:

(a) for a VTP family, the size of the deviation in the CO

emission values is equal to the size of the deviations established by the granting approval authority and referred to in Article 21(4), point (b)(ii) of this Regulation. The vehicles concerned are all vehicles of the VTP family that have the same combination of engine and transmission. If the investigation under Article 8(2)(b) determines that the cause of the failure referred to in that provision is a component listed in Article 12(1), points (a) to (f), (h) and (j), of Regulation (EU) 2017/2400, the vehicles concerned are all vehicles with that component;

(b) for an ISV air drag family, the Commission shall determine the size of the deviation in the CO

emission values for each vehicle subgroup of this ISV air drag family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for air drag. The corrected value for air drag is C

declared

multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles of the ISV air drag family concerned, referred to in Article 21(4), point (b)(i), and all vehicles for which the air drag value has been transferred from an air drag family of that ISV air drag family;

emission values for each vehicle subgroup and for each air drag family of this CFD family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for air drag. The corrected value for air drag is equal to the air drag value for the parent (worst case) vehicle of each air drag family, or in case this value is determined by CFD simulation, the default value for this air drag family, minus the declared air drag value for each vehicle concerned. The vehicles concerned are all vehicles of that CFD family, and all vehicles for which the air drag value has been transferred from an air drag family of that CFD family;

(d) for an ISV tyre family, the Commission shall determine the size of the deviation in the CO

emission values for each vehicle subgroup of this ISV tyre family, based on re-running the reference model in the simulation tool with the declared value and with the corrected value for the rolling resistance coefficient. The corrected value for the rolling resistance coefficient is RRC

declared

multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles registered after 1 July 2025 using tyres from the ISV tyre family concerned, referred to in Article 21(4), point (b)(i);

(e) for a mass test, the Commission shall determine the size of the deviation in the CO

emission values, based on re-running the fleet-average model in the simulation tool with the declared value and the corrected value for mass, for each vehicle sub-group of this manufacturer. The corrected value for mass is mass

declared

multiplied by the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned are all vehicles of the manufacturer;

(f) in case an artificial strategy is present according to the conclusion referred to in Article 21(4), point (b), the size of the deviation in the CO

emission values is equal to the size of the deviation referred to in Article 21(4), point (b)(ii). The vehicles concerned shall be determined based on the conclusion referred to in Article 21(4), point (b).

Article 23

Calculation and correction of the average specific CO

2 emissions of a manufacturer

1. Where the granting approval authority has issued a conclusion as referred to in Article 21(4), point (b), of this Regulation, the Commission shall, for the reporting period of the year in which the conclusion was issued and for the following reporting periods, apply the size of the deviation in CO

emission values to the vehicles concerned, as determined in accordance with Article 22, for calculating the average specific CO

emissions of a manufacturer in accordance with Article 4 of Regulation (EU) 2019/1242.

2. The Commission shall also apply the size of the deviation of the CO

emission values to the vehicles concerned, as determined in accordance with Article 22, for correcting the average specific CO

emissions of the manufacturer for the ten reporting periods prior to the reporting period of the year in which the conclusion was issued, but not earlier than the reporting period of the year 2025.

Article 24

Entry into force and application

This Regulation shall enter into force on the twentieth day following that of its publication in the

Official Journal of the European Union

This Regulation shall be binding in its entirety and directly applicable in all Member States.
