Participating in the CBMs





CBM Report Submission
    States Parties have different options to submit their CBMs:
    • hard copy:
      A hard copy with a note verbale as the cover can be sent from your permanent mission in Geneva, by post to:
      BWC Implementation Support Unit
      Office for Disarmament Affairs (Geneva Branch)
      Room C.117, Palais des Nations
      1211 Geneva 10

      Switzerland
    • electronic format:
      An electronic document (e.g. Microsoft Word or PDF document) can be sent to the e-mail address bwc@unog.ch. All e-mail submissions will be acknowledged.
    • eCBM facility:
      CBM reports can be generated and submitted directly through the new electronic CBM facility on the following website: https://bwc-ecbm.unog.ch/.

    Options for publication

    States Parties have the option to make their CBM submissions either publicly available or restricted to States Parties only. Please inform the ISU about your choice when submitting the CBM in hardcopy or electronic format.

    All CBMs, irrespective of their way of submission, will be posted by the ISU on the eCBM facility, either on the publicly accessible or the restricted part of the platform as per States Parties’ guidance received.

    Please note that the eCBM facility serves as the new electronic repository for all CBMs received since 1987.

    Missed the deadline?

    CBM returns are due by 15 April each year. If you miss this deadline, please do still submit the return as soon as you can: it is better if you submit a CBM after the deadline than not at all.


    eCBM facility

    The eCBM facility serves as the new repository for all CBMs received since 1987 and enables the online generation and submission of the annual CBM Reports. To facilitate the use of the platform, brief video clips and a separate user guide have been prepared.

    The Implementation Support Unit developed between 2017 and 2018 an electronic CBM platform in close collaboration with the Information and Communication Technology Service (ICTS) of the United Nations Office at Geneva and an external software developer. It was introduced at the BWC Meeting of Experts 3 on 13 August 2018.

    The development was made available through a voluntary contribution from Germany and funding from the European Union under its Council Decision 2016/51 in support of the BWC.




    The CBM Form

    Please find below MS Word versions of the blank CBM form, extracted from BWC/CONF.VII/7, in all official BWC languages:


    The CBM Guide

    This guide has been prepared by the United Nations Office for Disarmament Affairs with the support of the European Union, as part of the European Union’s 2008 Joint Action in support of the BWC and its 2012 Council Decision in support of the BWC.

    The aim of the guide is to provide practical advice and guidance to officials responsible for preparing CBM submissions. The guide includes:
    • Background information on the CBM process,
    • General advice for preparing to participate in the CBMs, and
    • Detailed guidance on gathering the specific information required for each form.

    This guide is intended only as a practical aid and has no formal status; please refer to the decisions of the respective Review Conferences for the formal requirements of the CBMs. The guide includes some suggestions for providing information in addition to that required by the CBM forms. These are only suggestions and are not intended to imply or confer any additional obligations on States Parties.

    The guide is available free to States Parties, and is available below in each of the six official
    languages of the United Nations (Arabic, Chinese, English, French, Russian and Spanish):

    Advice on completing the CBM Form

    Completing the CBM forms takes time, especially for the first year of participation. As each country's system of government is different, here are some general suggestions:
    • Start early: the CBM deadline is April 15. Collecting the necessary information typically requires contacting several different government ministries and agencies, a process which could take a long time.
    • Use information that has already been compiled: some of the information required for the CBMs may also be required for other purposes, such as reports to the WHO or those mandated by Security Council Resolution 1540.
    • Be clear: if there is nothing to declare for a particular measure, say so, rather than leaving the form for that measure blank. Similarly, if there is incomplete information, or information that will be provided later, say so on the form. Remember that the purpose of the CBMs is to increase transparency, therefore incomplete information is better than none.

    Questions or comments on the CBM Form?

    If you have problems or questions during the CBM process, please contact the ISU and we will do our best to help: see the contact page for details.

    The ISU is also interested in receiving perspectives on any obstacles to participating in the CBMs, as well as suggestions for improvements to the current system. Such ideas can be fed into ongoing efforts to facilitate participation in the CBMs and improve their utility to States Parties.
