Regime Overview

The Organization for the Prohibition of Chemical Weapons (OPCW), based in The Hague, the Netherlands, came into being at the entry into force of the Chemical Weapons Convention (CWC). States parties to CWC are members of the OPCW.

Principal Organs

Conference of the States Parties

The Conference is the OPCW’s principal organ, composed of representatives of all States Parties. A regular session of the Conference is to be held annually unless otherwise decided, and special sessions convened when necessary. The Conference can make decisions on any matters brought to its attention by the Executive Council or any of the States Parties. It elects members of the Executive Council and appoints the director-general. The Conference is responsible for taking measures necessary to ensure compliance and for redressing situations of non-compliance. It has the power to suspend the rights and privileges of States Parties in non-compliance upon the recommendation of the Executive Council, and may recommend collective measures if a State Party engages in activities prohibited by the Convention. In cases of particular gravity, the Conference is to inform the UN Security Council and the UN General Assembly.

Executive Council

The Executive Council is the executive organ of the OPCW. Each member has one vote, and the council decides on matters of substance by a two-thirds majority. The national chemical industry and political and security interests are among the factors that determine the composition of the Executive Council. The Council can request States Parties to take measures to redress situations of non-compliance. If the State Party concerned fails to take the requested action, the Council may inform the other States Parties and make recommendations to the Conference. In cases of particular gravity and urgency, the Council is to bring the matter directly to the attention of the UN General Assembly and UN Security Council. The Council can decide by a three-quarters majority to block challenge inspections.

There are 41 rotating members, representing 5 regional groupings:

  1. Africa
  2. Asia/Eastern Europe
  3. Latin America and the Caribbean
  4. Western European
  5. Others Group

H.E. Ambassador Lucian Fătu of Romania is the Chairperson for the 2023-2024 Executive Council. Current Vice-Chairs are the permanent representatives of Nigeria, Iraq, Brazil, and Italy.

Developments

Executive Council

2024

On 11 June, 2024, the OPCW released a report on their fact-finding mission (FFM) to Syria. The report investigated whether ISIS used chemical weapons to target members of the Syrian Arab Army. Security concerns, a lack of medical records, and challenges verifying specific claims hindered the investigation. Ultimately, the information obtained and analysed by the FFM was deemed insufficient to provide reasonable grounds to determine whether chemical weapons had been used in reported incidents that occurred on 9 August, 2017, in Qalib al-Thawr and on 8 November, 2017, in al-Balil, Hama Governorate, the Syrian Arab Republic.

The 105th session of the Executive Council convened 5-8 March. During the Conference, the U.S. delivered a statement on behalf of 47 states expressing concern over the death of Alexei Navalny and repeating the Secretary General’s calls for a “full, credible, and transparent investigation” into the cause of Navalny’s death.

2022

On 24 and 31 January the Technical Secretariat released the results of the fact-finding mission (FFM) in Syria investigating the potential use of chemical weapons in Marea and Kafr Zeita. In both cases, the FFM found “reasonable grounds” to conclude that chemical weapons were used.

On 18 February, the OPCW launched a new online reporting system, the Electronic Declaration Information System (EDIS), designed to aid national authorities and the chemical industry. This system digitizes the reporting obligation under articles III and IV of the CWC.

On 8 April, the OPCW released the first report by the newly established Investigation and Identification Team (IIT) which concluded that the Syrian Arab Air Force participated in the use of chemical weapons in Ltamenah, Syria in March 2017.

During the ninety-fourth session of the Executive council, held 7-10 July, the Council adopted a decision entitled “Addressing the Possession and Use of Chemical Weapons by the Syrian Arab Republic.” The decision condemns the use of chemical weapons reported by the IIT, calls for full Syrian cooperation with the Secretariat, and calls for the declaration of facilities where the chemical weapons used in March 2017 were developed, produced, stockpiled and stored, as well as the declaration of all the chemical weapons currently possessed by the nation.

On 2 October, the Fact Finding Mission (FFM) issued two reports on the investigation of the alleged use of chemical weapons in Saraqib, Syria in August 2016, and in Aleppo in November 2018. The results of analysis of the data collected by and made available to the FFM did not allow the FFM to determine whether chemicals were used as a weapon in these instances.

On 6 October, the Technical Secretariat released a report on the technical support activities provided by the technical secretariat to Germany in the wake of Alexei Navalny’s poisoning on 20 August. The report indicated that Mr. Navalny was exposed to a toxic chemical acting as a cholinesterase inhibitor. Biomarkers found in Mr. Navalny’s system showed that the agent used against him, while not listed in the CWC Annex, held structural characteristics similar to those of the Novichok agents in schedules 1.A.14 and 1.A.15.

The Executive council held its ninety-fifth session October 6-9 to address the implementation of the CWC. The session addressed the updates to the OPCW fact-finding mission in Syria, among other issues.

On 21 December, the OPCW published correspondence between the OPCW Technical Secretariat and the Russian Federation.

The Technical Secretariat replied that a team of experts could be dispatched, as long as necessary legal requirements were met and Mr. Navalny’s consent was obtained.

2019-2018

2019

During the 24th Conference of States Parties, two decisions (C‑24/DEC.4 and C‑24/DEC.5) were adopted, adding four additional entries to the list of Schedule 1 (A) chemicals under the Convention.

The Conference urged all states and the Secretariat to intensify their universality-related efforts with a view to increasing the number of States Parties to at least 180 by the end of 2006 and to achieving the universality of the convention 10 years after its entry into force. The Conference decided to continue with the action plan and to review progress of that plan at its Eleventh and Twelfth Sessions.

The Conference also recommended that the Executive Council at one of its sessions establish an open-ended working group to begin, in cooperation with the Secretariat, preparations for the Second Special Session of the Conference of the States Parties to Review the Operation of the Chemical Weapons Convention, which took place in April 2008.

The Conference also recommended to the Executive Council the establishment of an ad hoc, open-ended working group to examine a proposal to establish an OPCW office in Africa.

Conference discussion was based on recommendations represented in the report of the Executive Council of its activities between 28 June 2003 and 2 July 2004.

The Conference considered and adopted the Executive Council recommendation on the inclusion of an additional item on the list of approved equipment (C-9/ Dec.5). The Conference determined that the device, an environmental temperature logger, is essential to the safe maintenance of medical kits and laboratory work.

Participants also considered and adopted a recommendation to clarify the concept of “captive use” as it pertains to declarations of production and/or consumption of chemicals (C-9/Dec.6). The clarification, which defines the conditions under which certain chemicals may be produced and disposed, seeks to better enable the convention to meet its obligations of verification as listed in the Verification Annex to the convention.

The Conference further decided in favor of granting extensions to the Libyan Arab Jamahiriya and Albania in their effort to destroy Category 1 chemical weapons stockpiles. The Conference also granted a request by the Libyan Arab Jamahiriya to convert chemical weapons facilities for purposes not listed by the convention but found to be consistent with its tenants.

Before closing the session, the Conference elected 21 members to serve on the Executive Council for a new two-year term. They also considered and adopted the 2005 budget plan. Finally, the Conference underlined the importance of international cooperation in the field of chemical activities. International cooperation and assistance activities, the Conference noted, encourage and expedite concrete proposals and are considered a core objective of the organization.

2002

On 25 July, the First Special Session of the Conference of the States Parties reconvened to consider and to make a decision on the recommendation of the Executive Council to appoint Ambassador Rogelio Pfirter of Argentina as the Director-General of the Technical Secretariat of the OPCW. The Conference of the States Parties appointed Ambassador Pfirter by acclamation. The new Director-General’s four-year term of office commenced immediately upon his appointment. Prior to his appointment, Mr. Pfirter, a lawyer and a career diplomat, was the Under-Secretary for Foreign Policy in the Ministry of External Relations, International Trade and Worship, Argentina.

The 7th Session of the Conference of States Parties was held from 7-11 October in The Hague. The Conference, attended by 109 States Parties, adopted the 2003 OPCW’s program of work and budget. The 2003 OPCW budget was increased, for the first time in four years, by around 10 percent, resulting in a significant increase in Verification and International Cooperation and Assistance Programs. The Conference adopted a number of other policy decisions including a decision to grant an extension of the Russian Federation’s obligation to meet two of the Convention’s intermediate deadlines for the destruction of one percent and of 20 percent of its Category 1 chemical weapons stockpiles; a decision to grant an extension of another State Party’s obligation to meet the Convention’s timeline of April 2003 for the destruction of 20 percent of its chemical weapons stockpile; the adoption of requests for the conversion of nine former chemical weapons production facilities at Volgograd and Novocheboksarsk in the Russian Federation to peaceful purposes; a decision on guidelines for declarations of aggregate national data for the production, consumption, import, and export of Schedule 2 chemicals and for import and export of Schedule 3 chemicals.

The Conference also elected 21 new members to the 41-member Executive Council for a two-year term, which commenced on 12 May 2003. The Conference agreed that the First Review Conference of the Chemical Weapons Convention would be held in The Hague from 28 April-9 May 2003.

2001-2000

2001

The 6th Session of the Conference of the States Parties was held from 14-18 May in The Hague. The Conference was attended by 108 States Parties with Ambassador H. Reimann of Switzerland serving as the chair of the Conference. Since the Fifth Session, 10 new States Parties had joined the Organization, and the full program of work for 2000 had been completed. Inventory had been taken of all 70,000 tons of declared chemical weapons, nearly 20 percent of the declared munitions and containers had been destroyed, and more than half of the declared chemical weapons production facilities world-wide had been certifiably destroyed or converted to peaceful purposes. The OPCW’s Director-General, José M. Bustani, announced that the implementation of the Convention was working smoothly. The Secretary-General of the United Nations, Kofi Annan, praised the progress of the OPCW in implementing the Convention’s provisions, and expanding its activities. He called attention to the importance of garnering the full support of States Parties for the OPCW, especially to provide the necessary resources.

The most important decisions adopted by this session of the Conference were the program of work and budget for 2002, and a request from the Russian Federation for the conversion of a former chemical weapons production facility in Dzerzhinsk for peaceful purposes. The necessity of attaining the universality of the CWC was also endorsed. In addition, the Conference approved the relationship agreement with the United Nations, which had been signed at UN Headquarters in New York on 17 October 2000. The agreement was submitted to the UN General Assembly for approval in its 2001 session. The relationship agreement provides an opportunity for more intensive cooperation between the two organizations in areas of common interest, especially in the area of disarmament.

The Conference adopted a decision on the transfer of Schedule 3 chemicals to states that are not party to the Convention. This decision requires that end-use certificates be prepared when Schedule 3 chemicals are exported to states not party to the CWC, if the product to be exported contains 30 percent or more of a Schedule 3 chemical. An end-use certificate is not required for products identified as consumer goods packaged for commercial or individual purposes. Also prohibited is the re-transfer of Schedule 3 chemicals by the receiving states.

In regard to the budget, the Conference examined the cause of the Organization’s inability to collect the full amount of its budgeted income in 2000 and 2001. It requested that the Executive Council determine a solution for the structural deficiencies in the budget. As an exceptional one-time measure, the Conference authorized the Secretariat to retain the 1999 cash surplus, instead of redistributing it to States Parties. The Conference also called for voluntary contributions, to ensure that sufficient resources would be available to the OPCW to effectively carry out its operational mandate. In spite of the Organization’s funding problems, Mr. Bustani reiterated his intention to enhance program delivery, particularly in the areas of international cooperation and inspections. In addition, he praised the Conference’s recognition that operational activities would increase significantly in the coming few years.

2000

The OPCW stated on 25 January that the world’s declared stockpiles of 70,000 tons of chemical weapons and more than eight million munitions and bulk containers had been inspected by OPCW inspectors, and were subject to a stringent international verification regime. Three of the four countries that had declared possession of chemical weapons were now actively destroying them under the continuous scrutiny of OPCW monitoring teams. All of the 60 declared chemical weapons production facilities around the world had been inspected and sealed. Of these, 20 had been certified as destroyed, and five had been approved for conversion to peaceful purposes. To prevent the proliferation of chemical weapons, a stringent industrial verification regime had been put in place, involving inspections of facilities that produce or consume “dual-use” chemicals that could be used for both peaceful purposes and to create chemical weapons. By 11 May, more than 4,000 tons of chemical agents had been destroyed. Over a million chemical bombs, shells, and rockets had been destroyed. OPCW staff had made more than 700 inspections in 35 countries, including 460 visits to weapons storage and destruction sites and over 240 inspections of industrial chemical plants since the entry into force of the Convention. The Organization’s routine verification activities gave no indication that States Parties were not in full compliance with their fundamental obligations under the CWC, notwithstanding certain implementation-related inconsistencies and technicalities, which continued to occur. However, they were being addressed and corrected. To sum up, there was at the time no evidence to suggest that the essence of the CWC was not being upheld.

The 5th Session of the Conference of States Parties held in The Hague from 15-19 May reappointed the Director-General of the OPCW Mr. José Bustani for a second term of four years starting 13 May 2001. The OPCW reported considerable success in efforts to ban the production, stockpiling, or use of chemical weapons. More than 4,000 tons of chemical agents and over a million chemical bombs, shells, and rockets had been destroyed. OPCW staff had made more than 700 inspections in 35 countries, including 460 visits to weapons storage and destruction sites and over 240 inspections of industrial chemical plants. The Conference also recommended extending the deadline for Russia to destroy one percent of its chemical weapons. The Conference also approved a number of requests from Russia and the United Kingdom for the conversion of former chemical weapons production facilities to peaceful purposes. Delegates also welcomed two new members to the OPCW, Malaysia, and the Federal Republic of Yugoslavia, which joined the organization on 20 May.

In October, the OPCW signed a relationship agreement with the UN. Both organizations undertook, inter alia, to explore possibilities for cooperation in the provision of assistance if chemical weapons are used in the future. The agreement addresses the fostering of international cooperation in relation to the peaceful use of chemistry, and will thus contribute to economic and technological development. The CWC is among the 25 multilateral treaties identified by the UNSG as core treaties for the new millennium. The signing of this relationship agreement is accordingly expected to initiate a significant enhancement and intensification of the everyday relationship between the two organizations in the pursuit of their shared goals of enhanced security and peace.
