The use and testing of nuclear weapons has had catastrophic humanitarian and environmental consequences, which have been inadequately addressed by global policy. The Treaty on the Prohibition of Nuclear Weapons (TPNW), negotiated at the United Nations (UN) in 2017, is a categorical rejection of what had been the only weapons of mass destruction not yet banned by international law. But the TPNW also includes “positive obligations,” addressing the ongoing consequences of nuclear weapons use, testing, and related activities. These provisions were a major topic of discussion at the first meeting of states parties to the TPNW in June 2022 in Vienna, Austria. Discussions also centered on survivors’ voices and offered surprising moments of openness and collaboration between states parties and observer states that are not yet party to the TPNW, including some in nuclear alliances. The resulting Vienna Action Plan outlines a practical and forward-looking agenda, addressing the long-neglected impact of the more than 2,000 nuclear detonations in affected communities. It also provides opportunities for states to pursue other diplomatic priorities of the 21st century, including sustainable development, gender equity, disability justice, the rights of Indigenous Peoples, and mitigation of environmental pollution.
