        1) are based on the presentations (except presentation on QA/QC) delivered by the 
             Technical Support Unit of the Task Force on National Greenhouse Gas Inventories of the 
             Intergovernmental Panel on Climate Change (IPCC TFI TSU) in the Africa Regional 
             Workshop on the Building of Sustainable National Greenhouse Gas Inventory 
             Management Systems, and the use of the 2006 IPCC Guidelines for National 
             Greenhouse Gas Inventories (Swakopmund, Namibia, 24-28 April 2017);

        What do we want?
        •  Overall: a high quality inventory of anthropogenic emissions and removals 
           of greenhouse gases that is credible & convincing 
        •  Indicators of quality:
           -  Transparency
           -  Completeness
           -  Consistency
           -  Comparability
           -  Accuracy

        Transparency
        •  There is sufficient and clear documentation such that individuals or groups 
           other than the inventory compilers can understand how the inventory was 
           compiled and can assure themselves it meets the good practice 
           requirements for national greenhouse gas emissions inventories.

        Completeness
        •  Estimates are reported for all relevant categories of sources and sinks, and 
           gases. Geographic areas within the scope of the national greenhouse gas 
           inventory are recommended in these Guidelines. Where elements are 
           missing their absence should be clearly documented together with a 
           justification for exclusion.

        Consistency
       •  Estimates for different inventory years, gases and categories are made in 
          such a way that differences in the results between years and categories 
          reflect real differences in emissions. Inventory annual trends, as far as 
          possible, should be calculated using the same method and data sources in all 
          years and should aim to reflect the real annual fluctuations in emissions or 
          removals and not be subject to changes resulting from methodological 
          differences.
