Biological Weapons Convention

Biological weapons disseminate disease-causing organisms or toxins to harm or kill humans, animals or plants. They can be deadly and highly contagious. Diseases caused by such weapons would not confine themselves to national borders and could spread rapidly around the world. The consequences of the deliberate release of biological agents or toxins by state or non-state actors could be dramatic. In addition to the tragic loss of lives, such events could cause food shortages, environmental catastrophes, devastating economic loss, and widespread illness, fear and mistrust among the public.

The Biological Weapons Convention

The Biological Weapons Convention (BWC) effectively prohibits the development, production, acquisition, transfer, stockpiling and use of biological and toxin weapons. It was the first multilateral disarmament treaty banning an entire category of weapons of mass destruction (WMD).

The BWC is a key element in the international community’s efforts to address WMD proliferation and it has established a strong norm against biological weapons. The Convention has reached almost universal membership with 187 States Parties and four Signatory States.

Text of the Convention

The BWC itself is comparatively short, comprising only 15 articles. Over the years, it has been supplemented by a series of additional understandings reached at subsequent Review Conferences. The BWC Implementation Support Unit regularly updates a document that provides information on additional agreements which (a) interpret, define or elaborate the meaning or scope of a provision of the Convention; or (b) provide instructions, guidelines, or recommendations on how a provision should be implemented.

Formally known as “The Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on their Destruction”, the Convention was negotiated by the Conference of the Committee on Disarmament in Geneva, Switzerland. It opened for signature on 10 April 1972 and entered into force on 26 March 1975. The BWC supplements the 1925 Geneva Protocol, which had prohibited only the use of biological weapons.

States Parties to the Biological Weapons Convention undertook “never in any circumstances to develop, produce, stockpile or otherwise acquire or retain:

  1. microbial or other biological agents, or toxins whatever their origin or method of production, of types and in quantities that have no justification for prophylactic, protective or other peaceful purposes;
  2. weapons, equipment or means of delivery designed to use such agents or toxins for hostile purposes or in armed conflict.”

BWC States Parties have strived to ensure that the Convention remains relevant and effective, despite the changes in science and technology, politics and security since it entered into force. Throughout the intervening years, States Parties have met approximately every five years to review the operation of the BWC. Between these Review Conferences, States Parties have pursued various activities and initiatives to strengthen the effectiveness and improve the implementation of the Convention. A total of eight Review Conferences have taken place since the first one in 1980.
