Get ready for a week of high-level and civil-society events to tackle the urgent, existential threat of nuclear weapons. Nuclear weapons are a bigger threat than ever before. The war in Ukraine shows how nuclear weapons do not create safety but is a tool for terror and blackmail. The world urgently needs a reality-based plan to get rid of nuclear weapons, a plan that involves governments, elected representatives, international organisations, civil society and impacted communities. As governments gather for the first Meeting of States Parties to the UN Treaty on the Prohibition of Nuclear Weapons (TPNW) in Vienna, we’re bringing all parts of society together in Vienna and around the world to make our voices heard in a loud, unequivocal "no" to these weapons of mass destruction.
