The Chief Executives Board for Coordination (CEB) is the longest-standing and highest level coordination forum in the history of the United Nations.

The ACC was the predecessor of the CEB. The underlying premise in its creation was that an institutional mechanism was needed to draw the disparate parts of a decentralized system of specialized bodies - each with its own constitution, mandate, governing bodies and budgets - into a cohesive and functioning whole.

The UN Charter’s call for coordination through “consultation and recommendation” underscores the decentralized nature of the UN system. No central authority exists to compel compliance by organizations of the system to act in a concerted manner.  Coordination and cooperation are contingent upon the willingness of system organizations to work together in pursuit of common goals.

In the many decades since its establishment there have been a number of reviews and reforms of the coordination machinery. In 2001, ACC was renamed the UN System Chief Executives Board for Coordination. CEB meets twice a year under the chairmanship of the UN Secretary-General.


The Membership of the CEB consists of the 31 Organizations of the United Nations system. The United Nations Organization which is represented by the Secretary-General of the United Nations as Chair of CEB; 15 Specialized Agencies; 12 Funds and Programmes of the United Nations Organization and 3 Related Organizations.


Substantive inter-agency work is carried out by the CEB's three pillars: the High Level Committee for Programmes (HLCP), the High Level Committee for Management (HLCM) and the United Nations Development Group (UNDG). These bodies meet twice a year prior to CEB meetings, in order to ensure that their work feeds into CEB discussions.
