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.
