172. The representative of the European Union informed AC.3 that a final test procedure had been drafted; it would be considered by GRPE in the January 2023 session of GRPE (ECE/TRANS/WP.29/GRPE/2023/4). He added that two elements still needed to be finalized, namely brakes families and regenerative braking, which were expected to be completed before the consideration of the proposal by GRPE. He confirmed this UN GTR was expected to be used as part of the Euro 7 legislation expected to enter into force in the EU in 2025 and he encouraged all CPs to also adopt this proposal when considered by AC.3 in June 2023.

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.

169. Submitted for consideration and vote, the proposal for a new UN GTR on Laboratory Measurement of Brake Emissions for Light-Duty Vehicles (ECE/TRANS/WP.29/2023/79 and ECE/TRANS/WP.29/2023/80) was adopted on 21 June 2023 by consensus vote of the following contracting parties present and voting: Australia, China, European Union (representing Cyprus, Finland, France, Germany, Hungary, Italy, Lithuania, Luxembourg, Netherlands, Romania, Slovakia, Slovenia, Spain, and Sweden), India, Japan, Norway, Russian Federation, South Africa and United Kingdom of Great Britain and Northern Ireland.

170. Canada, Kazakhstan, Republic of Korea and United States of America abstained from voting.

187. The representative of the EU thanked all parties that contributed to the adoption by AC.3 of the new UN GTR No. 24 on Laboratory Measurement of Brake Emissions for Light-Duty Vehicles. He highlighted that thanks to this UN GTR, a globally harmonized procedure now exists to look at other sources of emissions beyond the exhaust.

188. He further added that, as said during the last session of AC.3, further improvement to the UN GTR were still on-going, for example with the development of vehicle-specific methodology for non-friction braking system. He concluded saying that a first amendment to this UN GTR No. 24 was expected during 2024.

189. The Chair of GRPE thanked the IWG on Particle Measurement Programme (PMP) for the development of the draft UN GTR and the timely delivery of the proposal that has been adopted by 22 contracting parties and was expected to be implemented in the EU as part of the Euro 7 proposal.

190. AC.3 agreed to keep this item on the agenda for the next session of AC.3.
