At the beginning of the first meeting of each ordinary session, the bureau elects a President and nine Vice-Presidents from among the representatives of the Parties, thus ensuring all geographical regions are represented by at least two members.

During each COP, the Bureau leads the work of governments, acting as a focal point.  

The Bureau of the COP takes the lead on issues that need follow-up post-COP and is in charge of preparing forthcoming COP meetings. The COP Bureau also often supervises specific, particularly demanding or sensitive tasks or processes that are carried out between the COP sessions.
