The governing body of the Protocol is the Conference of the Parties to the Convention on Biological Diversity serving as the meeting of the Cartagena Protocol on Biosafety (COP-MOP). The main function of this body is to review the implementation of the Protocol and make decisions necessary to promote its effective operation, including the operation of the BCH. These decisions may give further guidance to Parties on how they should implement the Protocol. The COP-MOP meets regularly, usually every one or two years.
