Treaty on the Prohibition of Nuclear Weapons

The Treaty on the Prohibition of Nuclear Weapons (TPNW) is the first globally applicable multilateral agreement to comprehensively prohibit nuclear weapons on the basis of international humanitarian law. It prohibits their use, threat of use, development, production, testing and stockpiling. It also commits States to clearing contaminated areas and helping victims. By providing pathways for the elimination of nuclear weapons, the TPNW is an indispensable building block towards a world free of nuclear weapons. This publication contains the text of the TPNW adopted on 7 July 2017 at the United Nations in New York. It is intended to promote understanding of the TPNW's rules and to facilitate its ratification and implementation by governments.
