Like most of these international committees, I believe they mostly facilitate agreements between sovereign states; I don't believe they have any legislative power themselves.
Maybe an analogy would be ICAO's (another "specialized agency of the UN") "Freedoms of the Air" [1] – they define the terminology, but it's still up to individual (or blocs of) nation states to actually grant them to each other, ratify recommendations etc.
