Article 36 played a key role in the achievement of the 2017 Treaty on the Prohibition of Nuclear Weapons: we elaborated the argumentation for a ban treaty without the nuclear armed states; convened key strategic discussion meetings; and worked with partners at the negotiations for the inclusion of obligations to address ongoing harm to people and communities from past nuclear weapons use and testing. Our most recent work on nuclear weapons until 2024 focused on working with partners towards the effective and inclusive implementation of these articles of the Treaty.
