Luxembourg

Umbrella state (NATO)

Luxembourg boycotted the negotiations on the Treaty on the Prohibition of Nuclear Weapons (TPNW) in 2017 and has consistently voted against the annual UN General Assembly resolutions on the Treaty, including in 2024. Luxembourg may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.

Latest developments

In January 2023, the then-Minister of Foreign Affairs of Luxembourg, Jean Asselborn, wrote in the newspaper Lëtzebuerger Land that ‘the TPNW has become a political instrument, which is not conducive to achieving the overarching goal of a world free of nuclear weapons’. He criticised TPNW states parties for aiming to isolate and stigmatise nuclear-armed states, and asserted that the First Meeting of States Parties (1MSP) to the TPNW in 2022 ‘turned out to be a quasi-anti-Western event’.1

Recommendations

  • Luxembourg 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.

  • Luxembourg should comply with its existing obligation under Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and pursue negotiations in good faith on nuclear disarmament.

  • Luxembourg 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.
