OPCW

The Organisation for the Prohibition of Chemical Weapons (OPCW) is an international organisation tasked with the implementation of the 1997 Chemical Weapons Convention. Its mission is to achieve a world free of chemical weapons and to promote the peaceful uses of chemistry around the globe.
With its 193 Member States, the OPCW oversees the global endeavour to permanently eliminate all chemical weapons. It is considered the most successful disarmament treaty with near universal membership, eliminating an entire class of weapons of mass destruction. As of 7 July 2023, 100% of all declared chemical weapon stockpiles have been destroyed under OPCW verification. For its extensive efforts in eliminating chemical weapons, the OPCW received the 2013 Nobel Peace Prize.
