One of the most common and serious problems identified in Parties’ inventory submissions by review teams is transparency. For example, national models and country-specific emission factors, which improve the accuracy of the inventory, are often not referenced or explained in sufficient detail, as is recommended by the IPCC Good Practice Guidance

Your evaluation of the accuracy, completeness, consistency, and comparability of a Party’s inventory submission is dependent upon it being transparent. Therefore, Parties should be strongly encouraged in your review findings to be as transparent as possible with their reporting.

As a review expert, you should request any information necessary that will enable you to assess a Party’s inventory submission, especially in the case of in-country reviews.  Preferably information should consist of published documents, peer reviewed in case of models, and country-specific EF and parameters.
