International Day for the Elimination of Nuclear Weapons, September 26th

Posted: 14th September 2025

Dear friends and colleagues,
 
We cordially invite you and/or your organization to endorse the Joint Appeal for Nuclear Abolition Day (September 26). We also invite you to join another event or action on Nuclear Abolition Day to reduce nuclear risks, prevent nuclear war and advance the global elimination of nuclear weapons.
 
UN Secretary-General António Guterres warns that “Growing geopolitical divisions and mistrust are driving tensions to new heights. Instead of dialogue and diplomacy being deployed to end the nuclear threat, another nuclear arms race is taking shape, and saber-rattling is re-emerging as a tactic of coercion. We need to stop the madness before it’s too late.”
 
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, a network of organizations, working in consultation with the United Nations Office of Disarmament Affairs, has established NuclearAbolitionDay.org.
 
You can be involved in Nuclear Abolition Day in one or more ways:
  1. Endorse the September 26 Joint Appeal  
    The appeal calls on governments to announce concrete plans at the UN High Level Meeting on Nuclear Disarmament on September 26 to reduce nuclear risks and prevent nuclear war, shift nuclear weapons budgets and investments to meet human and economic needs, and achieve the global elimination of nuclear weapons within a strict timeframe. 
    The appeal is open for endorsement by individuals and organizations and will be presented to world leaders at the UN on September 26. (See below for a sample of current endorsers. The full list is on the Joint Appeal page). 

  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. Organize or join an event 
    Post your Nuclear Abolition Day event on our events page to inform and engage others, or join an event already being planned.
We look forward to hearing from you and to building cooperation to ensure that Nuclear Abolition Day 2025 becomes a resounding success.
 
Yours,
 
Jackie Cabasso, Jasmine Chen, Jonathan Granoff, Chris Guillot, John Hallam, Natia Ninoshvili, Rebecca Shoot, Deepshikha Vijh and Alyn Ware
