  • OPCW - Organisation for the Prohibition of Chemical Weapons

    Headquartered in The Hague, the OPCW is an independent institution established in 1997 to implement the Chemical Weapons Convention (CWC). The OPCW monitors the activities of the states parties to the convention and assists them in matters of demilitarization, non-proliferation and cooperation and in their efforts to implement the CWC. All the ratifying states undertake to submit an annual report on their progress. Inspections are continuously made at the facilities established to destroy chemical weapons. All other relevant facilities are subject to regular inspection at various intervals, depending on the chemicals in question.
