States with nuclear-free security strategies

Ireland was at the forefront of the diplomatic process towards a treaty prohibiting nuclear weapons, including during the negotiation of the TPNW in 2017. Ireland has signed the TPNW and is in compliance with all of the prohibitions in Article 1, but has not yet ratified the Treaty.

Latest developments and background

The legislation to ratify the TPNW is currently before the Irish Parliament. On 26 September 2019, Ireland said in the UN General Assembly: “While the Nuclear Non-Proliferation Treaty remains the cornerstone of international disarmament and the nonproliferation regime, it was always envisaged that a separate legal instrument would be designed to give particular effect to Article VI’s disarmament provisions. The Treaty on the Prohibition of Nuclear Weapons, the first multilateral legal instrument on nuclear disarmament to be adopted in over 20 years, is the complementary instrument that the NPT anticipated and it conveys a powerful vision of a world free from these weapons of mass destruction. Ireland is currently taking the necessary steps to ensure that domestic legislation is enacted to allow Ireland to ratify the TPNW and we hope this will be completed before the end of this year.” (


  • Ireland should urgently ratify the TPNW, and continue to encourage other states to adhere to the Treaty.
