International Day for Disarmament and Non-Proliferation Awareness 2026; March 5th.

 

  FORUM: "Designing a World without Nuclear Weapons" International Day for Disarmament and Non-Proliferation Awareness 2026. The observance seeks to promote better awareness and understanding of disarmament issues among the public, especially young people. Since the founding of the United Nations, the goals of multilateral disarmament and arms limitation have been central to the Organization’s efforts to maintain international peace and security. Weapons of mass destruction, in particular nuclear weapons, continue to be of primary concern, owing to their destructive power and the threat that they pose to humanity. The excessive accumulation in conventional weapons and the illicit trade in small arms and light weapons jeopardizes international peace and security and sustainable development, while the use of explosive weapons in populated areas is seriously endangering civilians. New and emerging weapon technologies, such as autonomous weapons, pose a challenge to global security and have received increased attention from the international community in recent years.

Statement of the United Nations Secretary-General on the International Day for Disarmament and Non-Proliferation Awareness 2026; March 5th.

Our dream of peace is in peril.

The threat of nuclear weapons use is the highest in decades. Global tensions are pushing military spending to stratospheric levels. Small arms and light weapons are proliferating. And emerging technologies are making conflicts even deadlier.

We must lower the temperature. On this International Day for Disarmament and Non-Proliferation Awareness, I urge leaders to step back from the brink. Stop rattling the nuclear saber. Halt the arms races.

It’s time to invest in the architecture of peace, not the tools of war. That means living up to disarmament obligations. Rebuilding trust. And strengthening the systems and tools that prevent the proliferation, testing and use of deadly weapons.

Together, we can prevent catastrophes and ensure a safe and peaceful world for all.

António Guterres, United Nations Secretary-General.

The United Nations General Assembly has held three Special Sessions on Disarmament (SSOD), which fundamentally shaped the disarmament architecture and the subsequent discussions within it. Despite repeated calls since 1995, including recently in the Pact for the Future, a fourth special session remains elusive. This event examines the lasting impact of these sessions and explores a critical question: can the international community overcome current divisions to convene SSOD-IV?

EVENTS: Activities to Commemorate the International Day for Disarmament and Non-Proliferation Awareness Day 2025. on and around March 5th. Registration.

On March 5st, 2025: Side-event on “The History, Success, and Challenges of Nuclear Disarmament Education” - The Reppy Institute for Peace and Conflict Studies (Cornell University), the Permanent Mission of Kyrgyzstan to the United Nations, and the Office for Disarmament Affairs will be organizing a special lunchtime event marking the International Day for Disarmament and Non-Proliferation Awareness at UNHQ on March 5th. The title of the event is “The History, Success, and Challenges of Nuclear Disarmament Education.” The goal is for the attendees to hear from experts in the nuclear disarmament and education fields, to strategize on how best to inspire and educate students, and to ensure that students, especially from schools with less access to nuclear disarmament education, have an equal opportunity to study nuclear disarmament and nonproliferation. This event will also explore the gap between those creating educational resources on nuclear disarmament and the intended beneficiaries, as well as those involved in curriculum development. The panelists will represent a broad cross section of experts in the field disarmament education.

On 18 March 2025: Vienna Conversation Series event youth empowerment for disarmament - This Vienna Conversation Series event, planned in cooperation with the Kyrgyz Republic, commemorates the International Day for Disarmament and Non-Proliferation Awareness by underscoring the essential role of a diverse range of actors in promoting disarmament education, with a focus on youth engagement and empowerment. It will highlight new learning opportunities offered by UNODA and promote peer-to-peer exchange of experience to promote diverse applications to various UNODA programmes. The event also seeks to support the new calls for applications of UNODA learning programmes and boost their visibility among Member States, Vienna-based organizations, civil society, and, particularly youth groups, to ensure diverse applications. See additional information.

From 5 to 6 March 2025: Visibility among the Vienna community - The Office for Disarmament Affairs’ (ODA) Vienna Office will be kicking off a series of activities to mark the International Day. There will be an exhibition booth at the Rotunda of the Vienna International Center, featuring educational materials on the human cost of weapons and an interactive game on disarmament facts and fiction. Social media efforts, including promotion of ODA's e-learning opportunities, will continue during the week.

From 5 March to 13 April: Youth Leader Fund for a World without Nuclear Weapons launches Call for Applications - The Office for Disarmament Affairs (UNODA), with the generous support of the Government of Japan, is pleased to announce the launch of the second Call for Applications for the Youth Leader Fund for a World without Nuclear Weapons (YLF). Following the successful completion of Phase I, UNODA is seeking to select the next 100 young leaders from around the world to participate in an innovative online learning programme. Fifty of these participants will be given the opportunity to travel to Japan for a week-long study visit to Nagasaki and Hiroshima. During this visit, they will meet with hibakusha (survivors of the atomic bombings), engage with other youth advocates, and gain firsthand insight into the devastating consequences of nuclear weapons. Notably, Phase II of the programme is particularly focused on communication and storytelling as powerful tools for advocacy. The programme aims to bring together a diverse and geographically representative group of advocates for nuclear non-proliferation and disarmament, aged 18 to 29. The Call for Application closes on 13 April. For further details, please visit Disarmament Education Dashboard.

Statement of the Secretary-General for the International Day for Disarmament and Non-Proliferation Awareness 2025; March 5th.

Humanity’s future depends on investing in the machinery of peace, not the machinery of war.

Yet global tensions are increasing, the nuclear threat is rising, and guardrails are eroding. Meanwhile, small arms and light weapons are proliferating, and rapidly evolving technologies like Artificial Intelligence and quantum computing are deepening the dangers.

On this International Day for Disarmament and Non-Proliferation Awareness, I urge leaders to strengthen the systems and tools that prevent the proliferation, testing and use of deadly weapons and live up to their disarmament obligations.

I also call for a concerted effort in meeting the disarmament commitments contained in the recently adopted Pact for the Future. These commitments include working towards a world free of nuclear weapons, and new strategies to prevent the use of chemical and biological weapons, and to address the weaponization of outer space and the use of lethal autonomous weapons.

It’s time for leaders to put words into action, and invest in disarmament solutions and the peaceful future every person deserves.

United Nations Secretary-General.

International Day for the Total Elimination of Nuclear Weapons 2022; September 26th.

 FORUM: "Towards a new vision for nuclear disarmament and non-proliferation". International Day for the Total Elimination of Nuclear Weapons 2022.

On September 26th, We will continue o raise awareness to enhance public awareness and education about the threat posed to humanity by Nuclear Weapons and States Nuclear arsenals and the necessity for their total elimination. The observance of the United Nations Int'l Day for the Total Elimination of Nuclear Weapons; 26 September provides an occasion for the world community to reaffirm its commitment to Global nuclear disarmament as a priority.

Statement by the U.N. Secretary-General for the International Day for the Total Elimination of Nuclear Weapons 2022.


Mr. President of the General Assembly,
Excellencies,
Distinguished delegates,
Ladies and gentlemen.

We come together on this international day to speak with one voice.

To stand in defense of our world — and our future.

And to reject the claim that nuclear disarmament is some impossible utopian dream.

Last month, I had the honour of visiting Hiroshima and meeting the brave survivors of the 1945 attack, the hibakusha.

Each year, their numbers grow smaller.

But their message grows louder.

Nuclear weapons are the most destructive power ever created.

They offer no security — just carnage and chaos.

Their elimination would be the greatest gift we could bestow on future generations.

Excellencies,

The Cold War brought humanity within minutes of annihilation.

Now, decades after the fall of the Berlin Wall, we can hear once again the rattling of nuclear sabres.

Let me be clear.

The era of nuclear blackmail must end.

The idea that any country could fight and win a nuclear war is deranged.

Any use of a nuclear weapon would incite a humanitarian Armageddon.

We need to step back.

Last month, at their tenth Review Conference, the parties to the Treaty on the Non-Proliferation of Nuclear Weapons came close to consensus on a substantive outcome.

Despite meaningful engagement by parties across all three of the Treaty’s pillars, this unique moment failed to result in the outcome we so desperately need.

We are disappointed — but we will not give up.

I urge all States to use every avenue of dialogue, diplomacy and negotiation to ease tensions, reduce risk and eliminate the nuclear threat.

More broadly, we also need a new vision for nuclear disarmament and non-proliferation.

My proposed New Agenda for Peace calls for meaningful disarmament and developing a common understanding of the multiple threats before us.

We need to take into account the evolving nuclear order, including all types of nuclear weapons and their means of delivery.

And we need to address the blurring lines between strategic and conventional weapons, and the nexus with new domains of cyber and outer space.

I pledge to work closely with all Member States to forge a new consensus around how we can collectively defuse these threats and achieve our shared goal of peace.

Excellencies,

As the world comes together for the General Assembly, we have an opportunity to shape a more peaceful, trusting and sustainable future.

Without eliminating nuclear weapons, there can be no peace.

There can be no trust.

And there can be no sustainable future.

Let’s leave this year’s Assembly with a new commitment to work towards the peaceful future we all seek.

Thank you.

Disarmament Week (24–30 October)

The annual observance of Disarmament Week, which begins on the anniversary of the founding of the United Nations, was called for in the Final Document of the General Assembly 1978 special session on disarmament -  (resolution S-10/2) . States were invited to highlight the danger of the arms race, propagate the need for its cessation and increase public understanding of the urgent tasks of disarmament.

In 1995, the General Assembly invited governments, as well as NGOs, to continue taking an active part in Disarmament Week  (resolution 50/72 B, 12 December 1995). It invited the Secretary-General to continue using United Nations information entities as widely as possible, to promote a better understanding among the public of disarmament problems, and the aims of the Week.
