All NWFZs combined: | 84,000,000 | 114 | 39% of the world population | |

A nuclear-weapon-free zone (NWFZ) is defined by the United Nations as an agreement that a group of states has freely established by treaty or convention that bans the development, manufacturing, control, possession, testing, stationing or transporting of nuclear weapons in a given area, that has mechanisms of verification and control to enforce its obligations, and that is recognized as such by the General Assembly of the United Nations. [4] NWFZs have a similar purpose to, but are distinct from, the Treaty on the Non-Proliferation of Nuclear Weapons to which most countries including five nuclear weapons states are a party. Another term, nuclear-free zone, often means an area that has banned both nuclear power and nuclear weapons, and sometimes nuclear waste and nuclear propulsion, and usually does not mean a UN-acknowledged international treaty.
The NWFZ definition does not count countries or smaller regions that have outlawed nuclear weapons simply by their own law, like Austria with the Atomsperrgesetz in 1999. Similarly the 2+4 Treaty, which led to German reunification, banned nuclear weapons in the new states of Germany (Berlin and former East Germany), but was an agreement only among the six signatory countries, without formal NWFZ mechanisms.
Today there are five zones covering continental or subcontinental groups of countries (including their territorial waters and airspace), and three governing Antarctica, the seabed, and outer space which are not part of any state. The Antarctic, seabed, and space zones preceded all but one of the zones on national territories. Most of the Earth's oceans above the seabed are not covered by NWFZs since freedom of the seas restricts restrictions in international waters. The UN has also recognized one additional country, Mongolia, as having nuclear-weapon-free status.
NWFZs do not cover international waters (where there is freedom of the seas) or transit of nuclear missiles through space (as opposed to deployment of nuclear weapons in space).
As of 15 July 2009 [update] when the African NWFZ came into force, the six land zones cover 56% of the Earth's land area of 149 million square kilometers and 60% of the 195 states on Earth, up from 34% and 30% the previous year; however, only 39% of the world's population lives in NWFZs, while the nine nuclear weapons states have 28% of the world's land area and 46% of the world population.
The Antarctic, Latin American, and South Pacific zones are defined by lines of latitude and longitude, except for the northwestern boundary of the South Pacific zone which follows the limit of Australian territorial waters, and these three zones form a contiguous area, though treaty provisions do not apply to international waters within that area. In contrast, the Southeast Asian zone is defined as the territories of its members including their Exclusive Economic Zones, and the African zone is also defined as the countries and territories considered part of Africa by the OAU (now the African Union) which include islands close to Africa and Madagascar. An AU member, Mauritius, claims the British Indian Ocean Territory where Diego Garcia is currently a US military base.

Four NWFZ countries have nuclear plants to generate electricity. South Africa formerly had a nuclear weapons program which it terminated in 1989.
Argentina and Brazil are known to operate uranium enrichment facilities. Countries that had enrichment programs in the past include Libya and South Africa, although Libya's facility was never operational. Australia has announced its intention to pursue commercial enrichment, and is actively researching laser enrichment.
Argentina and Brazil also have plans to build nuclear submarines.

Several of the NWFZ treaties have protocols under which states outside the zone that have territories within the zone can bring the provisions of the NWFZ into force for those territories. All these territories are small islands except for French Guiana. The United States has signed but not ratified Protocol I to the Treaty of Rarotonga which would apply to American Samoa and Jarvis Island. The United Kingdom does not accept that African NWFZ is applicable to the Indian Ocean island of Diego Garcia which has a U.S. military base.
Few prevailing winds cross the Equator and effects of nuclear explosions in the Northern Hemisphere might send less fallout to the Southern Hemisphere.
The five southern NWFZs together cover all land in the Southern Hemisphere except East Timor, still in the process of joining ASEAN, and Atlantic and Indian Ocean islands belonging to non-NWFZ countries in the box (map) bounded by 60° S, 20° W, and 115° E, which combined have less than 8000 km2 of land area:
In 1994 states of the South Atlantic Peace and Cooperation Zone issued a "Declaration on the Denuclearization of the South Atlantic" which the U.N. General Assembly endorsed but the U.S., U.K., and France still opposed. [5]

The Latin American, African, South Pacific and Southeast Asian zones also cover most land in the tropics, but not some Northern Hemisphere areas south of the Tropic of Cancer. Most tropical land outside of NWFZs is in India and the Arabian Peninsula.
Little of the land area covered by the five southern Nuclear-Weapon-Free Zones extends north of the Tropic of Cancer: only northern Mexico, northern Bahamas, northern Myanmar, and North Africa. However, the Central Asian and Mongolian zones are entirely in the North Temperate Zone.
The majority of non-NWS non-NWFZ states are in Europe and the North Pacific and are members of (or surrounded by) collective security alliances with nuclear weapons states dating from the Cold War and predating the NWFZ movement.
Twenty-two states are not part of a NWFZ or a collective security bloc nor nuclear weapons states, twelve in the Middle East, six in South Asia, and four in the former Soviet Union. There have been NWFZ proposals for the Middle East (e.g. Nuclear program of Iran#Nuclear Weapon Free Zone in the Middle East, 2009 UN proposal, [6] 2011 IAEA forum [7] ), [8] the Korean Peninsula, Central Europe, South Asia, South-east Asia, and the Arctic. [9]
All countries without nuclear weapons, except South Sudan, are parties to the Non-Proliferation Treaty, as are the five NPT-sanctioned nuclear weapon states.
The UK, France, and the USA share a nuclear umbrella with the 29 other members of NATO, and the four European Union states not part of NATO (Austria, Cyprus, Ireland, Malta) are part of the EU's Common Security and Defence Policy.
The other European countries west of the former Soviet Union are small Western European states and surrounded by and aligned with the EU and NATO but not members (Switzerland and European microstates Liechtenstein, Monaco, San Marino, Vatican, Andorra), or Balkan states that have not yet joined the EU and NATO (Bosnia, Serbia and Kosovo).
Belarus and Armenia, along with some members of the Central Asian NWFZ, are allies of Russia in CSTO, the three Baltic states have joined NATO, and the GUAM states (Georgia, Azerbaijan, Ukraine, Moldova) are not party to either security treaty.
South Korea and Japan are American allies under its nuclear umbrella, while the three Micronesian states (Marshall Islands, Federated States of Micronesia, and Palau) are in a Compact of Free Association with the US.
India and Pakistan are nuclear-armed states and the six other South Asian states (Afghanistan, Sri Lanka, Maldives, Bangladesh, Nepal, Bhutan) are not part of a NWFZ or security bloc.
The six Gulf Cooperation Council states, the 5 other Arab League states outside Africa (Yemen, Jordan, Lebanon, Syria, Iraq), and Iran (see Nuclear program of Iran) are not nuclear weapons states and not part of a NWFZ. The UN General Assembly has urged establishment of a Middle East NWFZ, [10] and NPT Review Conferences in 1995 and 2010 called for a zone free of all weapons of mass destruction in the Middle East. [11] [12] [13] An International Conference For A WMD-Free Middle East was held in Haifa in December 2013 attended by citizens from all over the world concerned about the lack of progress in the official talks.
The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty whose objective is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as "Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare, de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states.
Nuclear disarmament is the act of reducing or eliminating nuclear weapons. Its end state can also be a nuclear-weapons-free world, in which nuclear weapons are completely eliminated. The term denuclearization is also used to describe the process leading to complete nuclear disarmament.
The Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean is an international treaty that establishes the denuclearization of Latin America and the Caribbean. It was proposed by Adolfo López Mateos, the President of Mexico, and promoted by the Mexican diplomats Alfonso García Robles, Ismael Moreno Pino and Jorge Castañeda as a response to the Cuban Missile Crisis (1962). For his efforts in favor of the reduction of nuclear weapons, García Robles was awarded the Nobel Peace Prize in 1982.
The New Agenda Coalition (NAC), composed of Brazil, Egypt, Ireland, Mexico, New Zealand and South Africa, is a geographically dispersed group of middle power countries seeking to build an international consensus to make progress on nuclear disarmament, as legally called for in the nuclear NPT.
Although Germany has the technical capability to produce weapons of mass destruction (WMD), since World War II it has refrained from producing those weapons. However, Germany participates in the NATO nuclear weapons sharing arrangements and trains for delivering United States nuclear weapons. Officially, 20 US-nuclear weapons are stationed in Büchel, Germany. It could be more or fewer, but the exact number of the weapons is a state secret.
The Treaty of Rarotonga is the common name for the South Pacific Nuclear Free Zone Treaty, which formalises a nuclear-weapon-free zone in the South Pacific. The treaty bans the use, testing, and possession of nuclear weapons within the borders of the zone.
The African Nuclear-Weapon-Free Zone Treaty, also known as the Treaty of Pelindaba, establishes a Nuclear-Weapon-Free Zone in Africa. The treaty was signed in 1996 and came into effect with the 28th ratification on 15 July 2009.
The Central Asian Nuclear-Weapon-Free Zone (CANWFZ) treaty is a legally binding commitment by Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan not to manufacture, acquire, test, or possess nuclear weapons. The treaty was signed on 8 September 2006 at Semipalatinsk Test Site, Kazakhstan, and is also known as Treaty of Semipalatinsk, Treaty of Semei, or Treaty of Semey.
The South Atlantic Peace and Cooperation Zone was created in 1986 through resolution A/RES/41/11 of the U.N. general assembly on Brazil's initiative, with the aim of promoting cooperation and the maintenance of peace and security in the South Atlantic region. Particular attention was dedicated to the question of preventing the geographical proliferation of nuclear weapons and of reducing and eventually eliminating the military presence of countries from other regions.
The Southeast Asian Nuclear-Weapon-Free Zone Treaty (SEANWFZ), or the Bangkok Treaty of 1995, is a nuclear weapons moratorium treaty between 10 Southeast Asian member-states under the auspices of the ASEAN: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam. It was opened for signature at the treaty conference in Bangkok, Thailand, on 15 December 1995 and it entered into force on March 28, 1997 and obliges its members not to develop, manufacture or otherwise acquire, possess or have control over nuclear weapons.
United Nations Security Council Resolution 1887, adopted unanimously on 24 September 2009, the Council addressed non-proliferation and the prevention of the spread of weapons of mass destruction in the world.
The 2010 Review Conference for the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) was held at United Nations Headquarters in New York City from 3 to 28 May 2010. The President of the Review Conference is Ambassador Libran N. Cabactulan of the Philippines. UN Secretary-General Ban Ki-moon used the opening of the conference to note that "sixty five years later, the world still lives under the nuclear shadow".
A security assurance, in the context of nuclear warfare, is an expression of a political position by a nuclear-armed nation intended to placate other non-nuclear-armed nations. There are two types of security assurance: positive and negative. A positive assurance states that the nation giving it will aid any or a particular non-nuclear-armed nation in retaliation if it is a victim of nuclear attack. A negative assurance is not the opposite but instead means that a nuclear-armed nation has promised not to use nuclear weapons except in retaliation for a nuclear attack against itself.
The Middle East nuclear weapon free zone (MENWFZ) is a proposed agreement similar to other nuclear-weapon-free zones. Steps towards the establishment of such a zone began in the 1960s led to a joint declaration by Egypt and Iran in 1974 which resulted in a General Assembly resolution. Following the 1995 NPT Review Conference, the International Atomic Energy Agency (IAEA) held a series of meetings involving experts and academics to consider ways to advance this process.
The Humanitarian Initiative is a group of states that evolved within the framework of the Nuclear Non-Proliferation Treaty (NPT) and nuclear weapons diplomacy more widely. 159 states subscribed to the last iteration of the initiative's Joint Statement in 2015. Since 2013, it led to a series of conferences exploring the Humanitarian Impact of Nuclear Weapons, culminating in the Humanitarian Pledge, issued by the Austrian Government, to "fill the legal gap for the prohibition and elimination of nuclear weapons". The Pledge has been endorsed by 108 governments as of 1 June 2015. The Humanitarian Initiative is seen as a direct answer to the lack of progress in nuclear disarmament.
The Treaty on the Prohibition of Nuclear Weapons (TPNW), or the Nuclear Weapon Ban Treaty, is the first legally binding international agreement to comprehensively prohibit nuclear weapons with the ultimate goal being their total elimination. It was adopted on 7 July 2017, opened for signature on 20 September 2017, and entered into force on 22 January 2021.
