12. WP.29 recalled the adopted programme of work for 2026 (ECE/TRANS/WP.29/2026/1) and noted that a first draft programme of work for 2027 would be circulated as an informal document at the next session of WP.29 in November 2026, based on inputs to be provided by GRs.

13. Mr. T. Naono (Japan), WP.29 Vice-Chair, presented the first report of the Informal Working Group on Prioritization (WP.29-199-12) which inter alia identified the following important topics for further discussion: Common understanding of prioritization High-level review of current GRs activities and resource needs Possible approaches to define prioritization (e.g. alignment with ITC strategies, majority views, priorities by each Contracting Party) Possible criteria for establishing new groups based on prioritization definition How to enhance the efficiency of Informal Working Groups (IWGs) and Task Forces (TFs).

14. A number of delegates strongly advocated the efforts of the IWG on Prioritization, provided their views on the above elements and prioritization process in general and asked for clarification of some provisions in WP.29-199-12. Following a brief exchange of views, WP.29 invited IWG to continue its work with participation of NGOs and welcomed the OICA offer to act as technical secretary to IWG.

15. Based on WP.29-199-01, WP.29 took note of a revised list of Working Parties, Informal Working Groups (IWGs) and Chairs, which is reproduced in annex II, including the updates agreed during the session.

16. WP.29 noted the calendar of sessions for 2026 (WP.29-199-02 and Annex III), including the change in para. 11 (e) above. WP.29 also took note of a draft calendar of meetings for 2027 (WP.29-199-03). In addition to the AC.2 request in para. 11 (f) above, WP.29 instructed the secretariat to explore the possibility of moving the GRE session in October to the previous week.

17. The representative of France introduced WP.29-199-16. The Chair of GRPE welcomed the proposal to perform a demonstration of retrofitted vehicle during the next session of GRPE. He reminded that GRPE had already held a similar demonstration during a hybrid workshop held in October 2024. Given the cross-cutting nature of the activities and the many GR experts involved, he wondered if a demonstration at WP.29 could also be relevant to showcase retrofitted vehicles. The representative of France offered to move the vehicle demonstration from the GRPE in October 2026 to WP.29 in November 2026. Thus, WP.29 noted that the potential demonstration would be held during the 200th session of WP.29 in November 2026, if feasible.

18. The representative of OICA wondered which base vehicles would be more appropriate for a viable business model, where most probably old vehicles and those with high-value equipment (such as cranes) could provide the best basis for a powertrain retrofit. The representative of France highlighted that the activities of the group focused on harmonized technical requirements to make sure that retrofitted vehicles were safe and environmentally friendly to use. He noted that viable business models were down to the economic actors deploying retrofit systems.
