63. The representative from the European Commission, Chair of the IWG on PMP, introduced GRPE-87-46 giving a status report of the activities of the IWG on PMP. He asked his colleague to introduce ECE/TRANS/WP.29/GRPE/2023/4 as amended by GRPE-87-40 as a new UN GTR on brake particulate emissions. He also introduced GRPE-87-41 as a final status report to the new UN GTR. The Chair shared his pride and gratitude with the work performed by the IWG on PMP to have a new UN GTR on such an important topic, and highlighted this proposal represented a milestone for GRPE and activities in the non-exhaust field.

64. The representative of the European Commission thanked the participants of the IWG on PMP for their collaboration in the development of this UN GTR and in particular the chairs of the IWG and task forces for putting together this new UN GTR proposal in a timely manner. She proposed that the UN GTR proposal be adopted today by GRPE, with the understanding that the IWG on PMP will continue to improve it by introducing changes as soon as possible, and preferably by June 2023, if feasible.

65. The representatives from France, Germany, Italy, Japan, the Netherlands, Sweden, Switzerland and the UK supported the proposal and agreed to a swift development of a vehicle-specific procedure to determine the share of non-friction brake events for hybrid and pure electric vehicles.

66. GRPE adopted ECE/TRANS/WP.29/GRPE/2023/4 as amended by GRPE-87-40, as reflected in Addendum 3 to the session report and GRPE-87-41, as reflected in Annex XII to the session report and requested the secretariat to submit them to WP.29 and AC.3 for consideration and vote at their June 2023 sessions as draft new UN GTR on Laboratory Measurement of Brake Emissions for Light-Duty Vehicles and its final status report respectively.

67. The representative from France, Co-Chair of the GRBP/GRPE Tyre Abrasion Task Force (TFTA) introduced GRPE-87-35. The representative from OICA thought that reference to C1, C2 or C3 tyre classification was not recognized outside of the EU. The Co-Chair of the TFTA informed that such classification were included in UN Regulations No. 30 or 54 for example.
