(1)

Type approval procedures referred to in Regulation (EC) No 595/2009 of the European Parliament and of the Council (2) have been amended by introducing new mission profiles, gear shift procedures and the full assessment of advanced drivers assistance systems in the simulation tool, giving rise to a decrease of the level of the CO2 emissions of the representative heavy-duty vehicles by more than 5 g CO2/km.

(2)

Therefore, the Commission is to adjust, in accordance with Article 11(2), point (a), of Regulation (EU) 2019/1242, for the first time, the reference CO2 emissions for certain vehicle subgroups set out in Commission Implementing Regulation (EU) 2025/2335 (3) and to determine the adjusted reference emissions as i = 1 and the non-adjusted reference emissions, set out in that Regulation, as i = 0).

(3)

To calculate the adjusted reference CO2 emissions, it is necessary to specify, in accordance with Article 11(3) of Regulation (EU) 2019/1242, a methodology to define representative vehicles, including their statistical weightings and the payload and passenger number values.

(4)

In order to comply with the requirement laid down in Article 11(3) of Regulation (EU) 2019/1242 and to achieve the best possible accuracy and limit the administrative burden for manufacturers, the representative vehicles for determining the adjusted reference CO2 emissions (i = 1) should be the subset of all vehicles for which data was reported in the reporting period of the year 2019 and with regard to which the data could be re-simulated in accordance with the amended type approval procedure.

(5)

The adjusted reference CO2 emissions were determined according to the adjustment procedure set out in point 1 of Annex II to Regulation (EU) 2019/1242, as explained in detail in a report publicly available on the JRC website under the reference JRC138612 and taking into account the updates of the simulation data provided by some manufacturers.

(6)

To have the result of the adjustment taken into account as soon as possible in the determination of the specific CO2 emissions targets and the CO2 emissions reduction trajectories, the adjusted reference CO2 emissions referred to in point 2 of Annex II to Regulation (EU) 2019/1242 should start applying from the reporting period of the year 2025 onwards.

(7)

Implementing Regulation (EU) 2025/2335 should therefore be amended accordingly.

(8)

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

(1)

in Article 1, the following second paragraph is added:

‘The adjusted reference CO2 emissions, referred to in point 2 of Annex II to Regulation (EU) 2019/1242, for the reporting period of the year 2025 and onwards are set out in the Annex to this Regulation.’;

(2)

the following Article 1a is inserted:

(3)

The Annex to Regulation (EU) 2025/2335 is replaced by the text in the Annex to this Regulation.
