The Chemical Weapons Ban
Facts and Figures
Foreword
The Chemical Weapons Convention (CWC) has been in force for over a decade. The international community is using this instrument to eliminate the possibility of developing, producing, using, stockpiling or transfering these dreadful weapons forever.
The mission of the Organisation for the Prohibition of Chemical Weapons (OPCW) is to implement the provisions of the CWC in order to achieve a world free of chemical weapons, and a world in which cooperation in the peaceful uses of chemistry is fostered. In doing this, our ultimate aim is to contribute to international security and stability, general and complete disarmament, and global economic development.
This brief overview of the CWC and of the OPCW provides an understanding of how the States Parties to this disarmament treaty are transforming their solemn pledge to renounce chemical weapons into a verifiable reality.
Over 98% of the world’s population lives within territories where the CWC has become the law of the land. It is our fervent hope that soon everyone will share the same protection.

A Global Convention to Ban Chemical Weapons
The CWC aims to eliminate an entire category of weapons of mass destruction by prohibiting the development, production, acquisition, stockpiling, retention, transfer or use of chemical weapons by States Parties. States Parties, in turn, must take the steps necessary to enforce that prohibition in respect of persons (natural or legal) within their jurisdiction.
All States Parties have agreed to chemically disarm by destroying any stockpiles of chemical weapons they may hold and any facilities which produced them, as well as any chemical weapons they abandoned on the territory of other States Parties in the past. States Parties have also agreed to create a verification regime for certain toxic chemicals and their precursors (listed in Schedules 1, 2 and 3 in the Annex on Chemicals to the CWC) in order to ensure that such chemicals are only used for purposes not prohibited.
A unique feature of the CWC is its incorporation of the 'challenge inspection', whereby any State Party in doubt about another State Party's compliance can request the Director-General to send an inspection team. Under the CWC's 'challenge inspection' procedure, States Parties have committed themselves to the principle of 'any time, anywhere' inspections with no right of refusal.
Making the Convention Work
To make sure that the CWC is implemented effectively, States Parties are obliged to designate or establish a National Authority. This body escorts OPCW inspections of relevant industrial or military sites; submits initial and annual declarations; assists and protects those States Parties which are threatened by, or have suffered, chemical attack; and fosters the peaceful uses of chemistry. In addition, the National Authority acts as the focal point in the State Party's interaction with other States Parties and the Technical Secretariat of the OPCW.
The Secretariat supports States Parties in their national implementation of the CWC. The focus of this work is to provide advice and assistance to the staff of National Authorities, in order to help them enhance their skills and expertise to facilitate effective, autonomous, national implementation. The Technical Secretariat coordinates and hosts regular meetings of the National Authorities from around the world. CD-ROM, DVD and website information packages on CWC implementation are available.
Every State Party must implement the provisions under the CWC at the national level. This includes enacting penal legislation encompassing all activities prohibited. Each State Party is obliged to provide other States Parties with its fullest cooperation to expedite prosecution. Legal experts have formed regional networks to facilitate the adoption of national legislation that bans and criminalises the misuse of chemicals as weapons.
Some figures on national implementation follow:
- 186 National Authorities have been established.
- 139 States Parties have informed the Organisation of the legislative and administrative measures taken to implement the Chemical Weapons Convention.
- 88 States Parties have legislation covering all key areas.
- Since 1997, over 2,800 participants, including more than 1,400 sponsored participants from all geographical regions have received support in the CWC's effective national implementation through OPCW meetings, workshops and training courses.
