Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments The General Assembly, Recalling its resolution 1 (I) of 24 January 1946 and resolution 79/35 of 2 December 2024, Recalling also the report of the Secretary-General entitled “Our Common Agenda”,1 in particular the reiteration by the Secretary-General of the commitment to achieve a world free of nuclear weapons and other weapons of mass destruction, and the disarmament recommendations of policy brief 9, entitled “A New Agenda for Peace”,2 presented by the Secretary-General on 20 July 2023, in particular the recognition that the existential threat that nuclear weapons pose to humanity must motivate us to work towards their total elimination and the recommendation to States to recommit urgently to the pursuit of a world free of nuclear weapons and reverse the erosion of international norms against the spread and use of nuclear weapons, and recalling further the importance of the Secretary-General’s disarmament agenda, Securing Our Common Future: An Agenda for Disarmament, Recalling further the Pact for the Future,3 namely actions 25 and 26, in which Member States recommit to the goal of the total elimination of nuclear weapons and seek to accelerate the full and effective implementation of respective nuclear disarmament and non‑proliferation obligations and commitments, Deeply concerned about the continued global peace and security challenges currently taking hold and the increased prominence being given by some States to _______________ 1 A/75/982. 2 A/77/CRP.1/Add.8. 3 Resolution 79/1. A/RES/80/39 Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments 25-19831 2/9 nuclear weapons in their security doctrines, the expansion of nuclear stockpiles, national plans by the nuclear-weapon States to expand, modernize and qualitatively improve nuclear arsenals, the disregard of negative security assurances, as well as plans by the nuclear-weapon States and States under extended nuclear security guarantees to maintain or increase the role of nuclear weapons in security doctrines, including with regard to the placement of nuclear weapons on the territory of non‑nuclear-weapon States, all of which contribute to the erosion of the disarmament and non‑proliferation regime and undermine the achievement of a nuclear-weapon free world, Alarmed that recent international tensions have taken an increasing nuclear dimension, particularly with regard to threats to use nuclear weapons and increasingly strident nuclear rhetoric, Deeply concerned about continuous actions that weaken the disarmament and non‑proliferation architecture and undermine key norms, such as the dismantling of core agreements among the nuclear-weapon States, including the Intermediate-Range Nuclear Forces Treaty, the Treaty on Open Skies, and the suspension of the Treaty on Measures for the Further Reduction and Limitation of Strategic Offensive Arms (New START Treaty), the only remaining bilateral arms control agreement between the United States of America and the Russian Federation, which is set to expire on 5 February 2026, and encouraging both Parties to ensure its full and effective implementation, to ensure also that current limits are not abandoned, and to urgently put in place arrangements for successor agreements, Emphasizing the urgent need for concrete measures to lower the risk of nuclear weapons use and to contribute to the prevention of nuclear war, including the reduction of the role of nuclear weapons in security doctrines, policies and plans, while underscoring that completely removing the risks associated with nuclear weapons requires their total, irreversible and verifiable elimination, Concerned about unpredictable new strategic factors involving developments in the fields of outer space, artificial intelligence and cyberspace, which have the potential to increase the risk of use or threat of use of nuclear weapons, Concerned also by extended nuclear deterrence arrangements that include the forward deployment of nuclear weapons, including on the territory of non‑nuclear- weapon States, which, inter alia, reduce response times and hasten nuclear decision- making, Recalling the joint statement on preventing nuclear war and avoiding arms races issued by China, France, the Russian Federation, the United Kingdom of Great Britain and Northern Ireland and the United States of America on 3 January 2022, affirming that “a nuclear war cannot be won and must never be fought”, and the statement by the New Agenda Coalition issued on 25 January 2022,4 calling for the five nuclear- weapon States to pursue tangible steps towards the total elimination of their nuclear arsenals in accordance with their obligations under article VI of the Treaty on the Non-Proliferation of Nuclear Weapons,5 Recalling also the decisions and the resolution adopted at the 1995 Review and Extension Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons,6 the basis upon which the Treaty was indefinitely extended, and the Final _______________ 4 CD/2226, annex. 5 United Nations, Treaty Series, vol. 729, No. 10485. 6 See 1995 Review and Extension Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, Final Document, Part I (NPT/CONF.1995/32 (Part I) and NPT/CONF.1995/32 (Part I)/Corr.2), annex. Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments A/RES/80/39 3/9 25-19831 Documents of the 20007 and the 20108 Review Conferences of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, and in particular the unequivocal undertaking by the nuclear-weapon States to accomplish the total elimination of their nuclear arsenals, leading to nuclear disarmament, in accordance with commitments made under article VI of the Treaty, Ever mindful that, to preserve the credibility and strength of the Treaty on the Non-Proliferation of Nuclear Weapons, nuclear-weapon States must implement their respective obligations and commitments under the Treaty and therefore redress the imbalance in implementation with regard to non‑nuclear-weapon States, Deeply concerned by the successive failures of the two previous Review Conferences of the Parties to the Treaty, and dismayed that States Parties to the Treaty were again unable to agree on actions that would strengthen the Treaty regime, enhance progress towards its full implementation and universality, or monitor implementation of the commitments made at the 1995, 2000 and 2010 Review Conferences, Noting with concern that the working group on further strengthening the review process of the Treaty on the Non-Proliferation of Nuclear Weapons could not agree on substantive outcomes and recommendations, Looking ahead to the pivotal 2026 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons, which will mark the culmination of the eleventh review cycle of the Treaty, underlining the significant expectation of many States Parties to that Treaty that the Review Conference will conclude successfully across all three pillars, and encouraging all its States Parties to spare no effort in working actively and constructively towards that goal, Recalling the founding concern of the New Agenda Coalition regarding the threat to humanity posed by the indefinite possession of nuclear weapons, and the attendant risks of their use or threat of use, and reaffirming the shared commitment to achieve a world free from nuclear weapons, Noting the widespread support in the tenth Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons for the view that enhanced accountability and transparency, including improving the process of reporting by nuclear-weapon States on their implementation of the nuclear disarmament commitments and obligations under the Treaty, would contribute to strengthening the review process, and that this fact was recognized by a majority of States Parties during the two first meetings of the Preparatory Committee for the 2026 Review Conference, Recalling that the total elimination of nuclear weapons, backed by legally binding assurances to ensure its verifiability and irreversibility, is the only absolute guarantee against the use or threat of use of nuclear weapons, and reiterating the legitimate interest of non‑nuclear-weapon States in receiving unequivocal and legally binding negative security assurances from nuclear-weapon States pending the total elimination of nuclear weapons, according to clear benchmarks and within an agreed time frame, Reiterating the expression of deep concern by the 2010 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons at the _______________ 7 2000 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, Final Document, vols.

Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments A/RES/80/39 5/9 25-19831 ratification of the Treaty by nuclear-weapon States and recent moves to withdraw ratification, which continue to make the entry into force of the Treaty impossible, with the associated risk that nuclear testing could be resumed, Underlining that pending the entry into force of the Comprehensive Nuclear- Test-Ban Treaty, it is necessary to uphold and maintain the moratorium on nuclear- weapon-test explosions or any other nuclear explosions, Welcoming the outcomes of the first, second and third Meetings of States Parties to the Treaty on the Prohibition of Nuclear Weapons, held in 2022 in Vienna, 11 and in 2023 and 2025 in New York,12 and the convening of the first Review Conference of the Treaty on the Prohibition of Nuclear Weapons from 30 November to 4 December 2026, and encouraging all States to participate in these proceedings, Welcoming also the commemoration and promotion of 26 September as the International Day for the Total Elimination of Nuclear Weapons, as established by resolution 68/32 of 5 December 2013, Deeply disappointed at the continued absence of progress towards multilateral nuclear disarmament, including the persistent failure to undertake new negotiations at the Conference on Disarmament, which has been unable to agree upon and implement a programme of work since 1996, representing a failure to deliver on its mandate for almost three decades, and that the Disarmament Commission has not produced a substantive outcome on nuclear disarmament since 1999, while recalling the limitations of its solely deliberative function, Underscoring the need to develop legally binding verification arrangements to support nuclear disarmament, in accordance with the principles of irreversibility, verification and transparency, that would provide the necessary confidence in the total elimination of nuclear weapons, 1. Condemns unequivocally all nuclear threats, whether explicit or implicit, and irrespective of the circumstances, and calls upon all States, in particular the nuclear-weapon States, to reject any normalization of nuclear rhetoric and, in particular, the threat of use of nuclear weapons, which only serves to undermine the disarmament and non‑proliferation regime and is against the Charter of the United Nations; 2. Stresses the fundamental role of the Treaty on the Non-Proliferation of Nuclear Weapons in achieving nuclear disarmament and nuclear non‑proliferation, and looks forward to achieving substantive progress during the 2026 Review Conference, in order to strengthen the Treaty and its review process, overcoming the obstacles that prevented a substantive outcome in the two previous Review Conferences held in 2015 and 2022; 3. Reiterates that each article of the Treaty on the Non-Proliferation of Nuclear Weapons is binding on the respective States Parties at all times and in all circumstances and that all States Parties should be held fully accountable with respect to strict compliance with their obligations under the Treaty; 4. Reaffirms the continued validity of the decisions, resolutions and commitments as agreed to at the 1995, 2000 and 2010 Review Conferences of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, and calls upon all States Parties, and in particular the nuclear-weapon States, to reaffirm and implement those decisions, resolutions and commitments; _______________ 11 See TPNW/MSP/2022/6. 12 See TPNW/MSP/2023/14 and TPNW/MSP/2025/11/Rev.1. A/RES/80/39 Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments 25-19831 6/9 5. Strongly urges nuclear-weapon States to implement the unequivocal undertaking to accomplish the total elimination of their nuclear arsenals leading to nuclear disarmament, as agreed at the 2000 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons, and as a means to ensure full implementation of article VI of the Treaty; 6. Urges all State Parties to the Treaty on the Non-Proliferation of Nuclear Weapons to implement their article VI obligations and to pursue multilateral negotiations without delay on effective measures for the achievement and maintenance of a nuclear-weapon-free world, recalling in particular the commitment of the nuclear-weapon States to accelerating concrete progress on the steps leading to nuclear disarmament; 7. Recognizes the need for an institutional mechanism to monitor the implementation of nuclear disarmament obligations; 8. Calls upon all States to give due prominence to the humanitarian imperatives that underpin nuclear disarmament and to the urgency of achieving it, including new evidence presented at the Conferences on the Humanitarian Impact of Nuclear Weapons, and those imperatives should inform all deliberations, decisions and actions relating to nuclear disarmament and nuclear non‑proliferation, including within the Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons; 9. Urges the nuclear-weapon States to make concrete reductions in the role and significance of nuclear weapons in all military and security concepts, doctrines and policies, pending their total elimination as agreed by the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons in the outcome documents of the 2000 and 2010 Review Conferences, and calls upon the nuclear-weapon States to include such information in their regular reporting details regarding progress towards this end; 10. Calls upon other States Parties to the Treaty that maintain a role for nuclear weapons in their military and security concepts, doctrines and policies to provide standardized information at regular intervals on, inter alia, measures taken to reduce the role and significance of nuclear weapons in military and security concepts, doctrines and policies, the number, type (strategic or non‑strategic) and status (deployed or non‑deployed, and alert status) of nuclear warheads within their territories, where applicable, and the number and type of delivery vehicles within their territories, where applicable; 11. Calls upon nuclear-weapon States to halt the quantitative increases and qualitative improvement of their nuclear arsenals and the development of advanced new types of nuclear weapons, and their means of delivery, including those that increase the risk of escalation; 12.

Stresses the necessity for enhanced transparency by the nuclear-weapon States with regard to their nuclear weapons capabilities and the implementation of their article VI obligations and nuclear disarmament-related commitments, and urges nuclear-weapon States to implement their nuclear disarmament obligations and commitments, both qualitative and quantitative, in a manner that strengthens accountability and enables all States Parties to regularly monitor progress, including through a standard detailed reporting format, thereby enhancing transparency and increasing mutual confidence, and facilitating the evidence-based evaluation of progress towards the full implementation of article VI and nuclear disarmament commitments; 16. Urges the nuclear-weapon States to voluntarily present, jointly or individually, implementation plans for the commitments and undertakings agreed to under the Treaty on the Non-Proliferation of Nuclear Weapons, including time frames and benchmarks for progress; 17. Also urges the nuclear-weapon States, pending the total elimination of their nuclear arsenals to which they have unequivocally committed, to remove all operational nuclear weapons from high alert status and to put in place, as a matter of urgency, appropriate legal and procedural safeguards aimed at reducing the risk of a nuclear detonation by accident, miscalculation or design; 18. Further urges the nuclear-weapon States to report at least twice during a Review Conference cycle at appropriate intervals, and to include in their reports to be submitted during the eleventh review cycle of the Treaty on the Non-Proliferation of Nuclear Weapons concrete and detailed information concerning the implementation of their obligations and commitments on nuclear disarmament; 19. Encourages States Parties to the Treaty on the Non-Proliferation of Nuclear Weapons to improve the measurability of the implementation of nuclear disarmament obligations and commitments, including agreement on but not limited to measures on improved and more structured reporting by the nuclear-weapon States, tools such as a set of benchmarks and timelines and/or similar criteria, in order to ensure and facilitate the objective evaluation of progress, as well as the establishment of a structured dialogue on this issue at the meetings of the Preparatory Committee for the 2026 Review Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons and at the Review Conference on these improved and more structured reports, facilitated by the Chairs of the Preparatory Committee meetings, who will provide a joint report to each Review Conference that includes specific recommendations, targets and indicators, to improve the monitoring of and reporting on article VI and disarmament-related commitments; 20. Encourages the nuclear-weapon States, as part of their national reporting, to include details on their plans related to the modernization of nuclear weapons; their nuclear capabilities, including quantity, type and status of nuclear warheads, as well as delivery vehicles; doctrinal issues; risk reduction measures; de-alerting measures; quantity of fissile material; and the number and type of weapons and delivery systems they have disarmed; 21. Encourages further steps by all nuclear-weapon States to ensure the irreversible removal of all fissile material designated by each nuclear-weapon State as no longer required for military purposes, and calls upon all States to support, within the context of the International Atomic Energy Agency, the development of appropriate nuclear disarmament verification capabilities and legally binding verification arrangements, thereby ensuring that such material remains permanently outside military programmes in a verifiable and irreversible manner; A/RES/80/39 Towards a nuclear-weapon-free world: accelerating the implementation of nuclear disarmament commitments 25-19831 8/9 22. Calls upon all States Parties to the Treaty on the Non-Proliferation of Nuclear Weapons to work towards the full implementation of the resolution on the Middle East adopted at the 1995 Review and Extension Conference of the Parties to the Treaty on the Non-Proliferation of Nuclear Weapons,13 which is inextricably linked to the indefinite extension of the Treaty, and which remains valid until fully implemented; 23. Urges the co-sponsors of the 1995 resolution on the Middle East to exert their utmost efforts with a view to ensuring the early establishment of a Middle East zone free of nuclear weapons and all other weapons of mass destruction as contained in the 1995 resolution on the Middle East, including through support for the convening of the conference on the establishment of such a zone; 24. Calls upon all concerned parties referred to in decision 73/546 of 22 December 2018 to actively engage in the sessions of the conference to elaborate a treaty to establish a Middle East zone free of nuclear weapons and all other weapons of mass destruction, on the basis of arrangements freely arrived at by all States of the region; 25. Calls upon all States Parties to spare no effort to achieve the universality of the Treaty on the Non-Proliferation of Nuclear Weapons, and in this regard urges India, Israel and Pakistan to accede to the Treaty as non‑nuclear-weapon States promptly and without conditions, and to place all their nuclear facilities under International Atomic Energy Agency safeguards, and further calls upon South Sudan to join the Treaty at the earliest opportunity; 26.
