The OPCW oversees the global endeavour to permanently eliminate chemical weapons and is the implementing body of the Chemical Weapons Convention. Since its entry into force in 1997 the Convention has become the fastest growing arms treaty in history with 192 States Parties. Over 90 percent of all chemical arsenals declared by existing States Parties have been destroyed under OPCW verification. This is an unprecedented achievement in disarmament. For its extensive efforts in eliminating chemical weapons, the OPCW received the 2013 Nobel Prize for Peace.
