About International Day for the Total Elimination of Nuclear Weapons

International Day for the Total Elimination of Nuclear Weapons is observed on 26 September. It is a United Nations disarmament observance focused on the objective of a nuclear-weapon-free world and on public awareness of the humanitarian and security consequences of nuclear weapons.

The Day is part of a much longer UN nuclear-disarmament agenda, but its specific annual observance was created in 2013 following the General Assembly’s first high-level meeting on nuclear disarmament.

Why International Day for the Total Elimination of Nuclear Weapons matters

The observance focuses on total elimination rather than only testing, non-proliferation or arms-control limits. Those issues overlap, but they are institutionally distinct.

Public education around the Day can examine disarmament commitments, humanitarian consequences, verification and diplomacy without presenting complex treaty obligations as if every State has identical legal duties.

History of International Day for the Total Elimination of Nuclear Weapons

On 26 September 2013, the General Assembly held its first-ever high-level meeting on nuclear disarmament. The Movement of Non-Aligned Countries then advanced a follow-up draft through Indonesia.

On 5 December 2013, the General Assembly adopted resolution A/RES/68/32, which designated 26 September as the International Day for the Total Elimination of Nuclear Weapons.

United Nations sources state that the Day was observed for the first time on 26 September 2014 and has been observed annually since.
