Open Skies Consultative Commission

The Open Skies Consultative Commission is the implementing body for the Open Skies Treaty. It consists of representatives from each of the 32 States Parties to the Open Skies Treaty. The OSCC meets at the headquarters of the OSCE in Vienna, Austria.

Background

The Open Skies Treaty, in force since 2002, establishes a framework of unarmed aerial observation flights over the entire territory of its signatories. It was designed to enhance mutual understanding and confidence by giving all participants, regardless of size, the possibility to obtain information on military or other activities of concern to them. The Treaty is the most wide-ranging international effort to promote openness and transparency of military forces and their activities.

Open Skies Treaty Membership

The 32 States Parties to the Open Skies Treaty are: Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Slovak Republic, Slovenia, Spain, Sweden, Turkey, United Kingdom and Ukraine. Kyrgyzstan has signed but not yet ratified. Two of the original signatories—the United States and the Russian Federation—withdrew from the Treaty in 2020 and 2021, respectively.

The Treaty depositories are Canada and Hungary.

Function of the Commission

The main functions of the Open Skies Consultative Commission, which convenes in monthly plenary meetings, are to:

  • consider questions relating to compliance with the Treaty;
  • seek to resolve ambiguities and differences of interpretation emerging during Treaty implementation;
  • consider and decide on applications for accession to the Treaty; and
  • review the distribution of flight quotas annually.

The Commission members meet at OSCE headquarters in Vienna. In addition to the plenary meetings, the Commission has several informal expert working groups that discuss technical issues related to sensors, notification formats, aircraft certification, and rules and procedures.

The Open Skies Consultative Commission was established by Article X and Annex L of the Treaty and has been in session since the Treaty was signed in March 1992. It takes decisions by consensus and has adopted more than 90 since its creation. Decisions taken by the Commission enter into force with the Treaty and have the same duration as the Treaty.
