Identification of misreported vehicles

3.—(1) Where a misreported vehicle is identified, the Secretary of State must notify the manufacturer of the vehicle.

(2) Within one month of receiving a notification under paragraph (1) (\"#regulation-3-1\"), a manufacturer may provide to the Secretary of State information to show that the vehicle was correctly certified as a vocational vehicle.

(3) Where, following receipt of any information under paragraph (2) (\"#regulation-3-2\"), the Secretary of State considers that a misreported vehicle was incorrectly certified as a vocational vehicle, the Secretary of State must correct the manufacturer’s average specific CO2 emissions(6 (\"#f00006\")) for the reporting period of the relevant year(7 (\"#f00007\")) to take that vehicle into account.

Procedure for correcting average specific CO2 emissions

4.—(1) The Secretary of State may correct a manufacturer’s average specific CO2 emissions using the correct CO2 values of a misreported vehicle.

(2) Where the correct CO2 values of a misreported vehicle are not already available, the Secretary of State may request that a manufacturer determine the correct CO2 values according to the technical characteristics of that vehicle.

(3) Where a manufacturer determines the correct CO2 values of a misreported vehicle following a request under paragraph (2) (\"#regulation-4-2\"), the manufacturer must use the same version of the simulation tool as used for the original determination of the CO2 values of that vehicle, unless the Secretary of State permits otherwise.

(4) Where a manufacturer fails to determine the correct CO2 values of a misreported vehicle within two months of receiving a request under paragraph (2) (\"#regulation-4-2\"), the Secretary of State may correct the manufacturer’s average specific CO2 emissions using the formula set out in the Schedule (\"#schedule\").

(5) In this regulation—

“correct CO2 values” means the CO2 emissions and fuel consumption of a misreported vehicle as a non-vocational vehicle, determined using the simulation tool in accordance with Commission Regulation (EU) 2017/2400 (\"https://www.legislation.gov.uk/eur/2017/2400\");

“simulation tool” means an electronic tool used to determine CO2 emissions and fuel consumption of vehicles as provided for in Article 5 (\"https://www.legislation.gov.uk/eur/2017/2400/article/5\") of Commission Regulation (EU) 2017/2400 (\"https://www.legislation.gov.uk/eur/2017/2400\").

Regulation 4

ScheduleFormula for correcting average specific CO2 emissions

1. Where regulation 4 (\"#regulation-4\")(4) (\"#regulation-4-4\") applies, the average specific CO2 emissions of the manufacturer must be corrected as follows for the reporting period of the relevant year:

(\"http://www.legislation.gov.uk/uksi/2025/794/images/uksi_20250794_en_001\")

where—

avgCO2sg is the average specific CO2 emissions of the manufacturer defined in Annex I, point 2.2. of Regulation (EU) 2019/1242 (\"https://www.legislation.gov.uk/eur/2019/1242\");

Vsg is the number of new heavy-duty vehicles of the manufacturer in the vehicle sub-group sg, excluding vocational vehicles, in accordance with Article 4 (\"https://www.legislation.gov.uk/eur/2019/1242/article/4\")(a) (\"https://www.legislation.gov.uk/eur/2019/1242/article/4\") of Regulation (EU) 2019/1242 (\"https://www.legislation.gov.uk/eur/2019/1242\");

ΣV is the sum over all heavy-duty vehicles of the manufacturer in the vehicle sub-group sg, in accordance with regulation 3 (\"#regulation-3\")(3) (\"#regulation-3-3\");

CO2Vv is the average of the CO2 emissions in g/tkm of the vocational vehicle v for all different combinations of mission profiles, load conditions and fuel types, reported in accordance with Regulation (EU) 2018/956 (\"https://www.legislation.gov.uk/eur/2018/956\");

Vocsg is the number of heavy-duty vehicles of the manufacturer in the vehicle sub-group sg, in accordance with regulation 3 (\"#regulation-3\")(3) (\"#regulation-3-3\").

2. The corrected average specific CO2 emissions of the manufacturer (avgCO2sg)corr must replace the average specific CO2 emissions of the manufacturer avgCO2sg for the purposes of Regulation (EU) 2019/1242 (\"https://www.legislation.gov.uk/eur/2019/1242\").

Explanatory Note

(This note is not part of the Regulations)

These Regulations introduce a procedure to identify heavy-duty vehicles that have been misreported as vocational vehicles and to correct such misreporting for the purposes of Regulation (EU) 2019/1242 (\"http://www.legislation.gov.uk/european/regulation/2019/1242\").

Regulation (EU) 2019/1242 (\"http://www.legislation.gov.uk/european/regulation/2019/1242\") sets CO2 emission performance standards for new heavy-duty vehicles, exempting vocational vehicles from the calculation of average specific CO2 emissions which inform the CO2 emissions reduction target set for each manufacturer.

These Regulations enable the Secretary of State to ensure that vehicles which were incorrectly certified as vocational vehicles are not exempt from manufacturers’ average specific CO2 emissions calculations.

These Regulations enable the Secretary of State to engage with manufacturers to obtain the correct information regarding such vehicles, and to amend the calculation of the average specific CO2 emissions of such manufacturers accordingly.

A full impact assessment has not been produced for this instrument as no, or no significant, impact on the private, voluntary or public sector is foreseen.
