The mission of the U.S. Delegation to the Organization for the Prohibition of Chemical Weapons is to lead global efforts to deter the use of chemical weapons, verifiably eliminate their existence, and enhance the implementation of the Chemical Weapons Convention.
The Organization for the Prohibition of Chemical Weapons (OPCW) is charged with implementing the Chemical Weapons Convention, which bans the development, production, stockpiling, transfer, and use of chemical weapons. The Convention entered into force in 1997 and has achieved near-universality, with over 190 member states. The OPCW was awarded the Nobel Peace Prize in 2013 for its distinguished record in working towards their mission — to implement the provisions of the Chemical Weapons Convention to achieve their vision of a world free of chemical weapons and the threat of their use, in which chemistry is used for peace, progress, and prosperity.
The permanent staff of the U.S. Delegation to the OPCW is led by the permanent representative with the rank of Ambassador who represents U.S. national security interests at this international organization. The delegation enjoys the management services shared with the U.S. Mission to the Netherlands.
