About Us

The Organisation for the Prohibition of Chemical Weapons is the implementing body for the Chemical Weapons Convention, which entered into force on 29 April 1997. The OPCW, with its 193 Member States, oversees the global endeavor to permanently and verifiably eliminate chemical weapons.

The ultimate aim of the OPCW is to achieve our vision of a world free of chemical weapons in which chemistry is used for peace, progress, and prosperity, and to contribute to international security and stability, general and complete disarmament, and global economic development. Under the OPCW's oversight 96% of the chemical weapons stockpiles declared by possessor States have been verifably destroyed.

The OPCW was awarded the Nobel Peace Prize in 2013 for its extensive efforts to eliminate chemical weapons.

Our mission for a world free of chemical weapons makes people's lives better. Apply to be a part of our team to make the world a better place for all.
