Annex I Parties are requested to submit their Biennial Reports (BRs) to the secretariat every two years (decision 2/CP.17). The fifth BR (BR5) should be submitted as early as the annual greenhouse gas inventory submission for the inventory year 2020 is provided to the UNFCCC (e.g., 15 April 2022), but no later than 31 December 2022, in order to provide Parties with the opportunity to include the inventory data in these reports (decision 6/CP.25). Annex I Parties shall use the BR Common Tabular Format (CTF) application when preparing their tabular format of the BRs (decision 19/CP.18). The BR CTF application is accessible only for the nominated national CTF compilers.

From 2017, both, the textual part of BRs and the BR CTF tables (generated from the CTF application) shall be submitted using the submission portal. Questions relating to the use of the submission portal should be addressed to reporting-ai@unfccc.int.

Note: All submissions received from Parties are posted “as received”. The publication of Party submissions on this website does not imply the expression of any opinion whatsoever on the part of the UNFCCC or the secretariat of the United Nations concerning the legal status of any country, territory, city or area or of its authorities, or concerning the delimitation of its frontiers or boundaries as may be referred to in any of the submissions.
