The Roadmap to 2MSP

In June 2022, states parties, observers and civil society gathered in Vienna for the first meeting of states parties (1MSP) to the Treaty on the Prohibition of Nuclear Weapons. Article 8 (2) of the Treaty obligates states parties to convene meetings on a biennial basis. On the week of 27 November 2023, the second meeting (2MSP) will take place in New York at the United Nations’ Headquarters. 

On the final day of the first MSP, an Action Plan was agreed upon by states parties. The action plan called upon the establishment of working groups to oversee and implement the actions before the second meeting. This includes art. 4 on verification matters; art. 6 & 7 on provisions on victim assistance, environmental remediation and international cooperation; and art. 12 on universalising the Treaty. 

In “The roadmap to 2MSP”, experts will tell you about the trajectory from the first to the second meeting. They will provide special insight about the intersessional period, where to push your governments and what to expect in New York in November–December 2023.

You will also get the opportunity to ask questions. This is the place to be to prepare yourself for the 2MSP.
