Proposal of amendments to promote harmonization, legal certainty, and environmental protection in the 08 series of amendments.

This proposal introduces the new Utility Factor (UF) approach proposed in the Euro 6e emissions type-approval legislation. In addition, as a result of the application of the new tyre labelling Regulation (EU) 2020/7401, this proposal introduces a revised format of the table with tyre energy efficiency classes according to rolling resistance coefficients (RRC), in-line with the format proposed in the Euro 6e emissions type-approval legislation.

The current format of the type approval mark illustrated in Annex A3 is not consistent with the requirements of Section 5.2.1, which may unintentionally lead to approval marks not being issued or accepted in the correct format. The proposed amendment to Annex A3 aligns the illustrated approval marks with the requirements of Section 5.2.1 and Schedule 4 of Revision 3 of the 1958 Agreement. This proposal is available with tracked changes in a pdf version and in a .docx format.

Input from the GRVA task force on the screening of WP.29 regulations for their fitness in application to Automated Driving Systems and ADS vehicles (FADS).

Updated proposal for the new GTR on laboratory measurement procedures for brake particulate emissions from the PMP informal group. This document is also available with tracked changes in pdf version and .docx format.

Report on the background and development of the text for a new UN GTR on laboratory measurement procedures for brake particulate emissions.

Proposal to add assembly plant(s) to the approval information document.

Proposal to promote harmonisation in use of reference fuels for testing, including hydrogen fuel, based on the following justifications:

1. The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R85 may not allow this. In this case, manufacturers have to prepare fuels with different characteristics, which is costly and requires a long time due to the current inconsistent situation.
2. We believe that the use of test fuels for gaseous and particulate pollutant measurement tests should be a priority as a precondition for the introduction of more stringent emission levels.
3. Hydrogen fuelled vehicles are covered in UN Regulation No. 83, but hydrogen is not yet covered in UN R49 and UN R85.
4. Hydrogen fuelled engines could be one complementary option to reduce CO₂ emissions of future heavy-duty vehicles.
5. Therefore, hydrogen fuel should be integrated in UN R49 and UN R85 for better alignment with UN R83.

Proposal to allow higher tolerance for pressure measurement under paragraphs 4.7 and 4.8 (+ aligned intake and exhaust) in order to avoid refusal of test due to the non-compliance of pressure accuracy and based on the low impact on the αd. Value or approach (linearity?) to be discussed.

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.
