The TPNW

• The TPNW is the only legally binding global treaty that outlaws nuclear weapons.
• It was adopted on 7 July 2017 at a diplomatic conference established by the United Nations General Assembly.
• A total of 122 states, more than three-fifths of the world’s total, voted in favour of the Treaty’s adoption. Only one state participating in the conference, the Netherlands, voted against adoption, while a second, Singapore, abstained.
• The Treaty was opened for signature on 20 September 2017.
• The TPNW received its 50th ratification or accession on 24 October 2020, triggering entry into force on 22 January 2021.
• Article 8 of the TPNW provides for regular meetings of states parties.

The negotiation and adoption of the TPNW was a result of what has become known as the Humanitarian Initiative, where governments, the International Red Cross and Red Crescent Movement, various United Nations agencies, the International Campaign to Abolish Nuclear Weapons (ICAN) and other non-governmental organizations from 2010 began working together to reframe the debate on nuclear weapons.

The Humanitarian Initiative placed the catastrophic, persistent effects of nuclear weapons on our health, societies and the environment at the centre of the public and diplomatic discussions about nuclear disarmament and non-proliferation. It comprised three major governmental conferences on the humanitarian consequences of nuclear weapons, in Oslo, Norway in March 2013, in Nayarit, Mexico in February 2014, and in Vienna, Austria in December 2014. The Vienna conference, where 158 states participated, concluded with Austria presenting a pledge to cooperate in efforts to “fill the legal gap” in the international regime governing nuclear weapons, which became known as the Humanitarian Pledge. The Humanitarian Pledge was endorsed by 127 states in the months to follow.

In 2016 a so-called Open-Ended Working Group in the UN had three sessions with meetings to discuss new legal measures to achieve a world free of nuclear weapons. It recommended the negotiation of a treaty to prohibit nuclear weapons. In December the same year the UN General Assembly adopted by overwhelming majority a resolution to convene the conference in 2017 to negotiate “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”, which resulted in the negotiation and adoption of the TPNW.

TREATY ON THE PROHIBITION OF NUCLEAR WEAPONS

The States Parties to this Treaty,

Determined to contribute to the realization of the purposes and principles of the Charter of the United Nations,

Deeply concerned about the catastrophic humanitarian consequences that would result from any use of nuclear weapons, and recognizing the consequent need to completely eliminate such weapons, which remains the only way to guarantee that nuclear weapons are never used again under any circumstances,

Mindful of the risks posed by the continued existence of nuclear weapons, including from any nuclear-weapon detonation by accident, miscalculation or design, and emphasizing that these risks concern the security of all humanity, and that all States share the responsibility to prevent any use of nuclear weapons,

Cognizant that the catastrophic consequences of nuclear weapons cannot be adequately addressed, transcend national borders, pose grave implications for human survival, the environment, socioeconomic development, the global economy, food security and the health of current and future generations, and have a disproportionate impact on women and girls, including as a result of ionizing radiation,

Acknowledging the ethical imperatives for nuclear disarmament and the urgency of achieving and maintaining a nuclear-weapon-free world, which is a global public good of the highest order, serving both national and collective security interests,

Mindful of the unacceptable suffering of and harm caused to the victims of the use of nuclear weapons (hibakusha), as well as of those affected by the testing of nuclear weapons,

Recognizing the disproportionate impact of nuclear-weapon activities on indigenous peoples,

Reaffirming the need for all States at all times to comply with applicable international law, including international humanitarian law and international human rights law,

Basing themselves on the principles and rules of international humanitarian law, in particular the principle that the right of parties to an armed conflict to choose methods or means of warfare is not unlimited, the rule of distinction, the prohibition against indiscriminate attacks, the rules on proportionality and precautions in attack, the prohibition on the use of weapons of a nature to cause superfluous injury or unnecessary suffering, and the rules for the protection of the natural environment,

Considering that any use of nuclear weapons would be contrary to the rules of international law applicable in armed conflict, in particular the principles and rules of international humanitarian law,

Reaffirming that any use of nuclear weapons would also be abhorrent to the principles of humanity and the dictates of public conscience,

Recalling that, in accordance with the Charter of the United Nations, States must refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any State, or in any other manner inconsistent with the Purposes of the United Nations, and that the establishment and maintenance of international peace and security are to be promoted with the least diversion for armaments of the world’s human and economic resources,

Recalling also the first resolution of the General Assembly of the United Nations, adopted on 24 January 1946, and subsequent resolutions which call for the elimination of nuclear weapons,

Concerned by the slow pace of nuclear disarmament, the continued reliance on nuclear weapons in military and security concepts, doctrines and policies, and the waste of economic and human resources on programmes for the production, maintenance and modernization of nuclear weapons,

Recognizing that a legally binding prohibition of nuclear weapons constitutes an important contribution towards the achievement and maintenance of a world free of nuclear weapons, including the irreversible, verifiable and transparent elimination of nuclear weapons, and determined to act towards that end,

Determined to act with a view to achieving effective progress towards general and complete disarmament under strict and effective international control,

Reaffirming that there exists an obligation to pursue in good faith and bring to a conclusion negotiations leading to nuclear disarmament in all its aspects under strict and effective international control,

Reaffirming also that the full and effective implementation of the Treaty on the Non-Proliferation of Nuclear Weapons, which serves as the cornerstone of the nuclear disarmament and non-proliferation regime, has a vital role to play in promoting international peace and security,

Recognizing the vital importance of the Comprehensive Nuclear-Test-Ban Treaty and its verification regime as a core element of the nuclear disarmament and non-proliferation regime,

Reaffirming the conviction that the establishment of the internationally recognized nuclear-weapon-free zones on the basis of arrangements freely arrived at among the States of the region concerned enhances global and regional peace and security, strengthens the nuclear non-proliferation regime and contributes towards realizing the objective of nuclear disarmament,

Emphasizing that nothing in this Treaty shall be interpreted as affecting the inalienable right of its States Parties to develop research, production and use of nuclear energy for peaceful purposes without discrimination,

Recognizing that the equal, full and effective participation of both women and men is an essential factor for the promotion and attainment of sustainable peace and security, and committed to supporting and strengthening the effective participation of women in nuclear disarmament,

Recognizing also the importance of peace and disarmament education in all its aspects and of raising awareness of the risks and consequences of nuclear weapons for current and future generations, and committed to the dissemination of the principles and norms of this Treaty,

Stressing the role of public conscience in the furthering of the principles of humanity as evidenced by the call for the total elimination of nuclear weapons, and recognizing the efforts to that end undertaken by the United Nations, the International Red Cross and Red Crescent Movement, other international and regional organizations, non-governmental organizations, religious leaders, parliamentarians, academics and the hibakusha,
