The standards for the REDD+ mechanism were designed and approved using UNFCCC processes and procedures.  At the request of the Conference of the Parties (COP), all guidance, modalities and procedures for measurement, reporting, and verification under the REDD+ mechanism were developed by the two subsidiary bodies of the UNFCCC; the Subsidiary Body for Technological Advice (SBSTA) and the Subsidiary Body for Information (SBI), and Ad Hoc Working groups.  These groups rely on input from the Intergovernmental Panel on Climate Change (IPCC).  At the COP, countries then vote to approve these recommendations.
