Proposal for amendments to Annex 18 regarding special requirements for electronic control systems and for related transitional provisions for its entry into force.

Proposal to ensure consistency in the vehicle categories within scope across emissions regulations and with regional requirements within Europe.

1. The current scope of the proposed UN Regulation on RDE (GRPE/2023/3) does not cover all vehicle categories within scope of other UN emissions regulations relevant for light duty vehicles and is inconsistent with regional legislation within the UK and Europe.
2. The proposed amendment seeks to allow Contracting Parties to optionally apply this regulation for vehicle category N2 and for M2 vehicles above 3,500 kg technical permissible maximum laden mass when the reference mass is below 2,610 kg. This would enable equivalent coverage of the scope to regional requirements in Europe and the acceptance of a full UNECE emissions regulation package for those vehicle categories in that region.
3. Provisions relating to the extension of type approvals to vehicles with a reference mass not exceeding 2,840 kg have also been applied to categories M2 and N2 where Contracting Parties are applying the broader scope of vehicle categories.
