The OPCW, based in The Hague, is the global body that implements the Chemical Weapons Convention (in force since 29 April 1997); its members are States Parties from all over the world, not the European Union. Its work includes inspecting chemical industry so that weapons do not re-emerge, and helping member states protect themselves against chemical attack.

  • ✗ 1. The OPCW is the implementing body of a worldwide treaty with 193 Member States today (India is one); it is not an EU agency, and its formal ties are with the United Nations, not NATO.
  • ✓ 2. Through declarations and industry inspections under Article VI of the Convention, the OPCW works to prevent the re-emergence of chemical weapons, including by misuse of existing chemical facilities.
  • ✓ 3. Article X of the Convention covers assistance and protection: the OPCW helps members build national protection capacity and can send assistance if chemical weapons are used against them.

Remember · OPCW: The Hague; implements the Chemical Weapons Convention (1997); verifies destruction of stockpiles, inspects industry, gives assistance and protection; Nobel Peace Prize 2013.
