Abstract
National emission inventories are surrounded with uncertainties, which cannot be eliminated completely but can be managed. In this study methods were developed for the review and assessment of the quality of national inventories for the Kyoto Protocol. Four different approaches can be distinguished: quality control, inventory comparisons, model comparisons and direct emission measurements. In this paper the results of a comparison of national inventories with EDGAR and a comparison of aggregated national emissions with global budgets are presented. It was concluded that EDGAR is a good screening tool for completeness and comparability. With EDGAR large gaps and differences with the national inventories as reported to the Climate Convention could be identified. Differences could be explained in terms of the use of different emission factors or different activity data Aggregated totals compare well with modelled budgets, however uncertainties in both are large. Most National Communications were not transparent and a new common reporting format will be required to improve the detailed reporting needed for a proper review and assessment for compliance to the Kyoto Protocol.
