TPNW Meeting of States Parties sets out the next phase of work for the nuclear ban

On 7 March 2025, the Third Meeting of States Parties (3MSP) to the Treaty on the Prohibition of Nuclear Weapons (TPNW) adopted its report, a declaration, and a set of decisions about the intersessional structure, the international trust fund for victim assistance and environmental remediation, and a review process for the renewal of the mandate and terms of reference for the Scientific Advisory Group. 3MSP also decided to hold the first TPNW review conference within the week of 30 November–4 December 2026 in New York, with South Africa as the President of the conference. Beyond these decisions, the clearest outcome was the unified rejection by states parties and signatories of nuclear weapons and of nuclear deterrence theory. The declaration contends that nuclear deterrence “is posited on the very existence of nuclear risk, which threatens the survival of all,” and condemns “any rhetoric or actions that undermine the global taboo” against nuclear weapons. Many states, survivors, activists, academics, and others echoed this sentiment during the week-long meeting; and this approach has guided the ongoing work to implement the Treaty during the intersessional period. It is this firm, collective conviction against the bomb that will continue to drive the TPNW forward in these dangerous times.
