Media registration

Media representatives wishing to cover the conference are requested to register with the CTBTO Public Information Section by sending an email to [email protected]. Media representatives who are not accredited to the United Nations in New York must apply for media accreditation by 1 September 2023 here. Please note that media personnel will be limited to observing the conference from the designated booths or the mezzanine floor (accessible via the 1st floor entrance).


The CTBT bans all nuclear test explosions everywhere, by everyone, and for all time. Adherence to the Treaty is nearly universal, with 186 State Signatories and 178 ratifying states. However, to enter into force, the Treaty must be ratified by all 44 States listed in its Annex 2, for which eight ratifications are still required.

The CTBTO has established an International Monitoring System (IMS) to ensure that no nuclear explosion goes undetected. Currently, 305 certified facilities – of a total of 337 when complete – are operating around the world. The data collected by the IMS serves multiple purposes, including disaster mitigation, such as earthquake monitoring and tsunami warning. Additionally, it supports research in various fields, ranging from whale migration to climate change studies to predicting monsoon rains.
