TPNW Informal Working Group: Article 4 - Nuclear Disarmament Verification

Intersessional Progress on the TPNW

The First Meeting of States Parties established an informal working group on the implementation of Article 4, “in particular work related to the future designation of a competent international authority or authorities.” Article 4 of the TPNW “Towards the elimination of nuclear weapons” outlines the pathways for the elimination of nuclear weapons of nuclear-armed states or states hosting other countries’ nuclear weapons on their territories who wish to join the TPNW.

The Vienna Action Plan includes four actions, Actions 15-18, dedicated to the implementation of Article 4, including discussing in the intersessional period the competent international authority or authorities identified in Article 4 to verify nuclear disarmament and elaborating on requirements for requests to extend the deadlines for nuclear disarmament.
