The secretariat publishes three types of inventory review reports for Annex I Parties:

1. Status Reports (published on the National Inventory Submissions webpage) provide information on the completeness and timing of the inventory submission.

2. Aggregate information on greenhouse gas emissions by sources and removals by sinks for Parties included in Annex I to the Convention 2023 synthesizes and compares inventory data across all Annex I Parties. Additionally, the secretariat prepares an Assessment Report for each Annex I Party subject to an individual review. However, the Assessment Report is provided only to the Party concerned .

3. Annual Inventory Review Reports are prepared by expert review teams and provide an assessment of the conformity of the inventory submitted by each Annex I Party with the UNFCCC reporting guidelines on annual inventories and, for Parties to the Kyoto Protocol, with the relevant reporting provisions under the Kyoto Protocol.
