Latest developments

Denmark may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Denmark delivered a statement on behalf of the Nordic states. ‘In challenging times, it is more important than ever to safeguard the nuclear disarmament, non-proliferation and arms control architecture,’ they said.1

On 25 June 2021, the Foreign Minister of Denmark, Jeppe Kofod, confirmed that there is no legal barrier to Denmark's accession to the TPNW. However, it would breach NATO 'solidarity', he informed a parliamentary committee.2

Three former Danish foreign ministers (Mogens Lykketoft, Holger K. Nielsen and Kjeld Olesen) were among the signatories to an open letter in September 2020 calling on current leaders in umbrella states to 'show courage and boldness' and join the TPNW.3

Recommendations

  • Denmark should renounce the possession and potential use of nuclear weapons on its behalf, and ensure that nuclear weapons do not have a role in its defence posture.
  • Denmark should comply with its existing obligation under Article VI of the NPT and pursue negotiations in good faith on nuclear disarmament.
  • Denmark should urgently adhere to the TPNW. Until it is in a position to do so, it should welcome the TPNW as a valuable component in the global disarmament and non-proliferation architecture, work with the Treaty's states parties on practical steps towards disarmament, and attend the meetings of states parties as an observer.
