US / Mexico Binational Nominations Initiative: World Heritage USA Task Force Update- El Camino Real de Tierra Adentro
(on a fast track to be completed before the end of 2026)As previously mentioned, the United States intends to exit UNESCO in effect December 31, 2026. However, there is some uncertainty how this effects the three active nominations (Okefenokee, Civil Rights, Central Park) and the planned extension: El Camino Real de Tierra Adentro. During the previous US withdrawal effective December 31, 2018 and up to the decision to rejoin UNESCO effective July 11, 2023 witnessed one new inscription (FLW Architecture) and one new nomination submitted (Hopewell). Thus nominations may continue as before, but the broader US withdrawal from the UN is more pronounced in both participation and funding. It remains to be seen how the Department of Interior will respond to an official request to submit a nomination file in the near future.
