Verification institutions

Global institutions

The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) was set up in 1996 with its headquarters in Vienna, Austria. It is an interim organization tasked with building up the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in preparation for the Treaty's entry into force as well as promoting the Treaty's universality.

The IAEA works for the safe, secure and peaceful uses of nuclear science and technology. Its key roles contribute to international peace and security

The Organisation for the Prohibition of Chemical Weapons (OPCW) is the implementing body of the Chemical Weapons Convention (CWC or Convention). The OPCW is given the mandate to achieve the object and purpose of the Convention, to ensure the implementation of its provisions, including those for international verification of compliance with it, and to provide a forum for consultation and cooperation among States Parties.

The UNMOVIC was created through the adoption of Security Council resolution 1284 of 17 December 1999. UNMOVIC replaced the former UN Special Commission (UNSCOM) and continued with the mandate to verify Iraq's compliance with its obligation to be rid of its weapons of mass destruction. On 29 June 2007, the Security Council adopted resolution 1762 (2007) which, inter-alia, decided to terminate immediately the mandate of UNMOVIC under the relevant resolutions.

Regional institutions

The Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL) is an inter-governmental agency created by the Treaty of Tlatelolco to ensure that the obligations of the Treaty be met. OPANAL is responsible for convoking regular and special general conferences and consultation meetings related to the established purposes, means, and procedures of the Treaty.

The Euratom Treaty establishing the European Atomic Energy Community (Euratom) was initially created to coordinate the Member States' research programmes for the peaceful use of nuclear energy. The Euratom Treaty today helps to pool knowledge, infrastructure, and funding of nuclear energy. It ensures the security of atomic energy supply within the framework of a centralised monitoring system.
