No pavilion has published its COP31 programme yet, as of 28 September 2026. Most have closed their calls for sessions and are selecting. Programmes have historically appeared in the two or three weeks before the conference, and sometimes during it.
The pattern this year is consistent across every pavilion we track. Calls for sessions opened between July and September, closed, and were followed by a page that says the schedule is coming. Several hosts promised a published programme in September and have not published one. The Cryosphere Pavilion, which plans more than seventy side events across the fortnight, still shows a placeholder.
There is no central release date because there is no central body. Each pavilion is a separate lease with its own host, its own selection committee and its own communications team. That is the reason a single agenda is worth building, and the reason it can only be built one host at a time.
If you are waiting on a specific pavilion, the most reliable move is to watch the host’s own page rather than the UNFCCC’s, and to ask the host directly. Programme drafts usually exist weeks before they are published.
