The Executive Council (EC) is one of the three principal organs of the Organisation for the Prohibition of Chemical Weapons (OPCW), alongside the Conference of the States Parties and the Technical Secretariat. It was established under Article VIII of the Chemical Weapons Convention (CWC), which entered into force on 29 April 1997.
The Council consists of 41 member states elected by the Conference for two-year terms, with seats distributed by regional group: Africa (9), Asia (9), Eastern Europe (5), Latin America and the Caribbean (7), and Western European and Others (10), plus one additional seat rotating between Asia and Latin America. Seat allocations also take into account which states have significant national chemical industries.
The EC functions as the executive body responsible for promoting effective implementation of, and compliance with, the CWC. Its core tasks include supervising the activities of the Technical Secretariat, considering reports on inspections and investigations of alleged use, concluding facility agreements with states parties, and reviewing the OPCW's draft programme and budget before submission to the Conference. Where it identifies serious compliance concerns, it may bring matters to the attention of the Conference or, in cases of particular gravity, refer them directly to the UN General Assembly and Security Council.
The Council normally meets several times a year at OPCW headquarters in The Hague, and can also convene in special sessions. Decisions on matters of substance generally require a two-thirds majority, while procedural matters need a simple majority. High-profile recent items on its agenda have included the destruction verification of Syria's declared chemical weapons stockpile following Syria's 2013 accession to the CWC, and the work of the Investigation and Identification Team (IIT) established in 2018 to attribute responsibility for chemical weapons use in Syria.
In Model UN circuits, the OPCW EC is simulated as a small, technical committee where delegates negotiate compliance findings, inspection mandates, and capacity-building programmes rather than broad disarmament declarations.
Example
In July 2020, the OPCW Executive Council adopted a decision giving Syria 90 days to declare the chemical weapons used in the 2017 Ltamenah attacks identified by the Investigation and Identification Team.
