Article 10 1.

In order to ensure the robustness and representativeness of the reference CO2 emissions of vehicle sub-groups to which a reporting period of the year 2024 or later year applies as the reference period according to point 3.2 of Annex I, the Commission shall assess the application of the conditions under which the reference CO2 emissions have been determined and determine whether those emissions have been unduly increased and, if so, how they are to be corrected.
