EU: Durability multipliers for gaseous pollutants of heavy-duty vehicles

 

The EU Commission has published a Commission Delegated amending Regulation (EU) 2024/1257 of the European Parliament and of the Council as regards setting out durability multipliers for gaseous pollutants of heavy-duty vehicles of categories M3, N2 and N3.

Regulation (EU) 2024/1257 of the European Parliament and of the Council of 24 April 2024 on the type-approval of motor vehicles and engines, as well as systems, components, and separate technical units intended for such vehicles with regard to their emissions and battery durability (Euro 7), introduces, among other measures, stricter requirements concerning the lifetime emission performance of vehicles, engines, and pollution control systems. The Regulation also establishes an “additional lifetime” period extending 25% beyond the vehicle’s “main lifetime.” To account for the deterioration of emission control systems during this extended period, durability multipliers are provided in Table 2 of Annex IV of the Euro 7 Regulation. Pursuant to Article 15(1)(f) of the Regulation, the present initiative proposes durability multipliers of 1.2 for gaseous pollutants emitted by heavy-duty vehicles in categories M3, N2, and N3, as specified in Table 2 of Annex IV.

Under Regulation (EU) 2024/1257, vehicles must comply with emission limit values not only during their main lifetime but also throughout the additional lifetime period. Durability multipliers are therefore necessary to reflect the potential deterioration of emission reduction systems beyond the main lifetime. Based on a technical assessment recommending a multiplier of 1.2 for heavy-duty vehicles in categories M3, N2, and N3—consistent with the standards applied to light-duty vehicles and category M2 vehicles—the proposal currently under consultation seeks to establish these durability multipliers. This measure aims to provide regulatory clarity for manufacturers of heavy-duty vehicles ahead of the mandatory application of the Euro 7 Regulation for these vehicle categories.
