Article 12 Checklist

A checklist of steps states parties can take to implement the Treaty on the Prohibition of Nuclear Weapons

June 2021

Under Article 12 of the Treaty on the Prohibition of Nuclear Weapons (TPNW), states parties are required to take steps to encourage other states to join the treaty–with the ultimate goal of bringing every state on board.

As the membership of the TPNW grows over time, the treaty’s norms will become more deeply entrenched and more widely accepted, and the pressure on hold-out states to end their support for nuclear weapons will intensify. It is up to each state party to decide how it goes about fulfilling its obligations under Article 12.

This checklist suggests a number of actions that a state party might take at the United Nations, at meetings of states parties, in regional forums, in bilateral dealings, and in its national context.
