Latest developments

At the Tenth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in August 2022, Colombia said: ‘The catastrophic, painful and prolonged humanitarian and environmental consequences of any use of nuclear weapons make it necessary to adopt urgent and effective measures for their total elimination … This is a moral imperative and an inescapable responsibility to present and future generations.’1 In a closing statement to the NPT Review Conference, Colombia and 64 other TPNW supporters urged ‘all states committed to attain and maintain a world without nuclear weapons to join the TPNW without delay’.2

In the First Committee of the UN General Assembly in October 2022, Colombia said that it is ‘our collective ethical and existential responsibility’ to work to avoid ‘the untold suffering’ and ‘global devastation’ wrought by nuclear weapons.3


  • Colombia should urgently ratify the TPNW.
