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 The Chair of the IWG on EVE detailed the reasons ECE/TRANS/WP.29/GRPE/2021/18 had been withdrawn from the agenda and invited GRPE to review the latest draft of the UN GTR on In-vehicle Battery Durability (GRPE-83-09).
