16. The expert from EC, leading the task force on the transposition of WLTP into the 1958 Agreement, presented GRPE-77-21 on the activities of his group.

17. He introduced the implications that the forthcoming UN Regulation on WLTP would have on UN Regulations No. 83 and No. 101. Four options are now under consideration to assist Contracting Parties (CPs) once the UN Regulation on WLTP has been created. He stated that further analysis would be undertaken in the coming months. The secretariat mentioned some practices from GRE on the procedure to freeze unused UN Regulations, that could be explored to properly manage UN Regulations Nos. 83, 101 and on WLTP.

18. He reported on the progress done on durability and Conformity of Production (CoP) provisions, where three approaches are considered. The provision on durability and CoP could either be developed as new UN GTRs, as annexes to UN GTR No. 15 or directly into the forthcoming UN Regulation on WLTP. The expert from EC expressed her preference to have them included directly into the forthcoming UN Regulation on WLTP. India reminded GRPE that such issue had already been raised previously (ECE/TRANS/WP.29/GRPE/75, para. 8.), when India expressed its preference for separate UN GTRs. India also mentioned the possibility to have that as part of a Mutual Resolution. The chair of IWG on WLTP stated that a UN GTR for CoP would only include technical requirements, not administrative ones. GRPE agreed to develop durability and CoP as annexes to UN GTR No. 15.

19. GRPE discussed the possible alternatives to structure the future UN Regulation on WLTP to address regional specificities. Following the consultation of the Office of Legal Affairs (OLA) by the secretariat, GRPE agreed to tentatively adopt approach 2 as noted in GRPE-77-21.
