Eliminating Chemical Weapons

The Chemical Weapons Convention is the most successful treaty on weapons of mass destruction in history. It comprehensively bans the use, development, production, stockpiling and transfer of chemical weapons. The Organisation for the Prohibition of Chemical Weapons (OPCW) is responsible for its implementation. It is based in The Hague, The Netherlands. 

The Use of Chemical Weapons

Sarin, VX, sulfur mustard gas, and chlorine may sound familiar as some of the materials used in chemical weapons. Attacks using chemical weapons have been seared in human memory. Unfortunately, in light of recent incidents, chemical weapons continue to claim the lives of innocent victims.

OPCW at Work

Member States that are part of the OPCW and possess chemical weapons pledge to destroy them. The OPCW verifies the destruction of declared chemical weapons stockpiles. The OPCW conducts regular worldwide inspections of chemical industrial facilities to monitor the manufacture of chemicals that could be used in the production of prohibited weapons. Working with a range of partners in industry and the scientific community, the OPCW also promotes the peaceful uses of chemistry.

The OPCW is evolving to address new challenges. Find out more by visiting the OPCW virtually during the 2020 edition of The Hague International Open Days/Just Peace Month.
