2. Mr. Rijnders, Chair of GRPE, opened the meeting and welcomed the participants.

3. GRPE adopted the provisional agenda of the ninetieth session (ECE/TRANS/WP.29/GRPE/2024/1), as updated and consolidated in GRPE-90-01-Rev.2, and GRPE-90-03 as a tentative running order.

4. The secretariat also briefly introduced GRPE-90-02-Rev.3, showing the schedule of meetings held in conjunction with this session of GRPE.

5. The informal documents distributed before and during the GRPE session are listed in Annex I of the session report. Annex II lists the informal meetings held in conjunction with this GRPE session. Annex III lists active Informal Working Groups (IWGs) of GRPE, task forces and subgroups, giving details on their Chairs, Secretaries and the end of their mandates.

6. The secretariat introduced GRPE-90-04, announcing details for this and next GRPE sessions. Given room constraints in the palais in 2024 and the rescheduling of the 91st session of GRPE in May, with limited time to prepare working documents, the Chair proposed to hold a GRPE session in October 2024.

7. GRPE requested the secretariat to cancel the May 2024 session of GRPE and agreed to host a session in October 2024. GRPE agreed to hold a series of virtual or hybrid events in January, May and October 2024 to support the activities to be achieved during official meetings. The secretariat informed GRPE the corresponding deadline for the submission of official documents to the 91st session of GRPE would therefore be Monday 22 July 2024.

8. For 2025, GRPE agreed to request a change to the schedule of GRPE meetings. GRPE requested the secretariat to schedule the 2025 GRPE sessions to be tentatively held on 25-28 March 2025 and 14-17 October 2025 in order to avoid the early January slot and the challenges faced this year, and the very busy May/June time period.
