CTBTO - Comprehensive Nuclear-Test-Ban Treaty Organization
Founded in 1997 and located in Vienna, the CTBTO's main task is to promote the Treaty and to make first development and the further development of nuclear weapons more difficult by operating a worldwide monitoring system. A global net of sensors serves as surveillance mechanism; furthermore, it intends to carry out on-site inspections after the Treaty has actually come into force. The organization can only fulfil its mission completely when the 44 states have ratified Annex 2 of the Treaty; so far, only 41 states have signed, and 36 have ratified the Treaty.
