• (1) These Regulations may be cited as the New Heavy-Duty Vehicles (Carbon Dioxide Emission Performance Standards) (Vocational Vehicles) Regulations 2025 and come into force on 29th July 2025.

• (2) These Regulations extend to England and Wales, Scotland and Northern Ireland.

Interpretation

2

In these Regulations—

• “Commission Regulation (EU) 2017/2400” means Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO₂ emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011[^f00002];

• “heavy-duty vehicle” means a vehicle to which any of points (a) to (d) of Article 2(1) of Regulation (EU) 2019/1242 apply;

• “manufacturer” has the meaning given in Article 3(10) of Regulation (EU) 2019/1242[^f00003];

• “misreported vehicle” means a heavy-duty vehicle that— was certified as a vocational vehicle based on the data reported by the manufacturer in accordance with Article 5 of Regulation (EU) 2018/956[^f00004]; and was registered as a non-vocational vehicle based on the data reported to the Secretary of State in accordance with Article 4 of Regulation (EU) 2018/956;

• “non-vocational vehicle” means a heavy-duty vehicle other than a vocational vehicle;

• “Regulation (EU) 2018/956” means Regulation (EU) 2018/956 of the European Parliament and of the Council on the monitoring and reporting of CO₂ emissions from and fuel consumption of new heavy-duty vehicles[^f00005];

• “Regulation (EU) 2019/1242” means Regulation (EU) 2019/1242 of the European Parliament and of the Council setting CO₂ 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;

• “vocational vehicle” has the meaning given in Article 3(16) of Commission Regulation (EU) 2017/2400.

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), 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), 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[^f00006] for the reporting period of the relevant year[^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), 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), the Secretary of State may correct the manufacturer’s average specific CO₂ emissions using the formula set out in the 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;

• “simulation tool” means an electronic tool used to determine CO₂ emissions and fuel consumption of vehicles as provided for in Article 5 of Commission Regulation (EU) 2017/2400.

Schedule — Formula for correcting average specific CO₂ emissions

1

Where 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:

$$( a v g C O 2 s g ) c o r r = ( V s g × a v g C O 2 s g + ∑ v C O 2 V v ) / ( V s g + V o c s g )$ where— avgCO2sg is the average specific CO₂ emissions of the manufacturer defined in Annex I, point 2.2. of Regulation (EU) 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(a) of Regulation (EU) 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(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; Vocsg is the number of heavy-duty vehicles of the manufacturer in the vehicle sub-group sg, in accordance with 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.

Explanatory note

(This note is not part of the Regulations)

Explanatory Note

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.

Regulation (EU) 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.

These Regulations, along with an Explanatory Memorandum, are available on the UK legislation website at http://www.legislation.gov.uk.
