International Day for the Elimination of Nuclear Weapons

Event Date: 26th September 2025
Location: Internet

The United Nations has declared September 26 to be the International Day for the Elimination of Nuclear Weapons. In order to build civil society action and cooperation for the day, an open group of organizations, working in consultation with the United Nations Office of Disarmament Affairs, has established NuclearAbolitionDay.org. You can be involved in NuclearAbolitionDay in one or more ways: 

1. Endorse the September 26 Joint Appeal 
   The appeal calls on governments to use the opportunity of the International Day for the Total Elimination of Nuclear Weapons and the UN High Level Plenary Meeting on September 26 to announce concrete plans to prevent nuclear war, shift nuclear weapons budgets and investments to strengthen the UN, advance peacekeeping and conflict resolution, accelerate steps to protect the climate, and meet human and economic needs as required under Article 26 of the UN Charter. The appeal is open to endorsement by individuals and organizations and will be presented to world leaders at the UN on September 26.
   
   
2.  Undertake the September 26 social media action Stop Nuclear Weapons: Peace is in our Hands.
   This action – which can be done by anyone, anywhere – is based on a hand raised with palm facing forwards, which is a universal message to stop. Hands are also what we use to greet each other, create things and build cooperation. For examples, please visit Stop Nuclear Weapons: Peace is in our Hands.
   
   
3. Join an event
   Post your Nuclear Abolition Day event on our calendar to inform and engage others, or join an event already being planned. See Nuclear Abolition Day Events
   
   
4. Add your organization as a Nuclear Abolition Day participating organization.
   Participating organizations are those that support Nuclear Abolition Day, and are planning on engaging in an action or event for the day, even if this is just to endorse the Appeal.
   Our impact on governments increases if we can show hundreds or thousands of participating organizations. Send your logo to [email protected] so that your organization can be added to the online list of participating organizations, which is on About Nuclear Abolition Day (scroll down to the logos).
