Exchange of views on scenarios

39. The representative of France reported (GRVA-24-15) on the outcome of a workshop on scenarios held in Paris (France) on 25-26 November 2025. He explained that, while the discussion had originally focused on the use of a scenario database, the participants were now concentrating on the development of an information sharing tool to support the creation of scenarios. He proposed Terms of Reference and Rules of Procedure for a new IWG on Information Sharing for Scenario-based Assessment (ISSA), prepared during the workshop.

40. The representatives of the European Commission, Germany, the Netherlands, the United Kingdom of Great Britain and Northern Ireland, as well as AAPC, ITU, OICA and ITU supported the proposal. The representative of Japan did not express concerns regarding the content, but raised issues with the structure. The representative of the United States of America suggested incorporating the activities into the IWG on ADS after June 2026.

41. The representative of France noted that the experts agreed on the work to be done but not on the structure. He proposed continuing the work on the exploration of potential procedures and the functioning of the information exchange, under the same arrangements while GRVA restructured its activities. GRVA agreed that one or two workshops would take place and decided to resume consideration of GRVA-24-13 at its next session.
