8. The Chair of IWG on EVE introduced the latest draft of the UN GTR on In-vehicle Battery Durability for electrified vehicles, as developed by the members of the IWG on EVE over numerous meetings over the last weeks and months (ECE/TRANS/WP.29/GRPE/2021/18, as amended by GRPE-84-01). He also introduced the final status report that accompanies the draft UN GTR (GRPE-84-02). He detailed the main elements of the new UN GTR that contain new approaches to monitor, report and verify the durability of batteries in electrified vehicles (GRPE-84-11).

9. The representatives from Japan, Sweden, US, the EU and OICA supported the proposals. GRPE adopted ECE/TRANS/WP.29/GRPE/2021/18 and GRPE-84-01, as amended by Addendum 1 and GRPE-84-02, as amended by Annex IV to the session report.

10. GRPE requested the secretariat to submit Addendum 1 and Annex IV to WP.29 and AC.3 for consideration and vote at their March 2022 sessions as draft UN GTR on In-Vehicle Battery Durability for electrified vehicles and its final status report, respectively.

11. The representative from OICA introduced their position on heavy duty battery durability (GRPE-84-14). The Chair of the IWG on EVE thanked OICA for their continuous support on the whole process and looked forward to forthcoming collaboration. The Chair requested further analysis on the possibility to use the existing framework as defined in GRPE-84-01 or the need for a new approach to consider heavy duty vehicle battery durability. The Chair of the IWG on EVE confirmed this task was expected to be tackled as soon as the phase 2 activities were initiated, expected in January 2022.

2. Mr. Rijnders, Chair of GRPE, opened the meeting, held as hybrid session, with all participants attending virtually because of the sanitary situation, and welcomed the participants. The Chair of the Informal Working Group (IWG) on Particle Measurement Programme (PMP) requested to remove ECE/TRANS/WP.29/GRPE/2021/17 from the agenda as the IWG on PMP could not finalize the proposal in time for a consideration by GRPE. The Chair of the IWG on Electric Vehicles and the Environment (EVE) requested to remove ECE/TRANS/WP.29/GRPE/2021/18 from the agenda as the IWG on EVE could not finalize the proposal in time for a consideration by GRPE.

3. GRPE acknowledged both requests by the IWGs on PMP and EVE and adopted the provisional agenda of the eighty-third session (ECE/TRANS/WP.29/GRPE/2021/9), as updated and consolidated in GRPE-83-03-Rev.4, and GRPE-83-02-Rev.1 as a tentative running order. GRPE took note of GRPE-83-01 on the organization of GRPE Informal Working Group (IWG) meetings held during the weeks prior to this meeting.

45. The Chair of the IWG on EVE detailed the reasons ECE/TRANS/WP.29/GRPE/2021/18 had been withdrawn from the agenda and invited GRPE to review the latest draft of the UN GTR on In-vehicle Battery Durability (GRPE-83-09).
