Guinea is preparing its third National Communication (NC) and first Biennial Update Report (BUR). For the first time ever, the production of the National Greenhouse Gas Inventory (NGHGI) is being lead directly by staff at ministries and other public bodies.

Guinea, through the FAO Global capacity-building towards enhanced transparency in the AFOLU sector (CBIT-AFOLU) project, recently benefitted from tailored virtual support to overcome these bottlenecks. The results of this process, which can help other Francophone countries in similar conditions meet the UNFCCC requirements under the Enhanced Transparency Framework (ETF), are presented in this case study
