Scientific Support for the Treaty on the Prohibition of Nuclear Weapons

Abstract

The Treaty on the Prohibition of Nuclear Weapons (TPNW) was negotiated and adopted in 2017, entered into force 2021, and currently has been signed by 93 states, of which 69 have ratified. The Treaty was born out of concern about the devastating impact of nuclear war and growing frustration among non-nuclear-weapon states about the lack of progress with serious nuclear disarmament [1, 2]. It is built on a solid scientific base, laid during a series of conferences on the humanitarian impact of nuclear weapons in 2013 and 2014, held in Norway, Mexico, and Austria [3]. The Treaty not only bans a wide range of activities related to nuclear weapons, but it also includes provisions for victim assistance and environmental remediation in places affected by nuclear weapons use and testing [4].Recognising the importance of science for the implementation of the Treaty, the 1st Meeting of States Parties in summer 2022 decided to create a Scientific Advisory Group (SAG) of 15 members, nominated by States parties, but acting independently. It mandated the SAG to produce a ”Report on the status and developments regarding nuclear weapons, nuclear weapon risks, the humanitarian consequences of nuclear weapons, nuclear disarmament and related issues”, which was delivered in autumn 2023. Furthermore, the SAG was tasked to ”identify and engage scientific and technical institutions in States parties and more broadly to establish a network of experts to support the goals of the Treaty”.The presentation will highlight some key points of our first report [7], and outline our current plans for building the Scientific Network. We also plan to offer a Townhall Meeting for those interested in network membership.
