UNFCCC Reporting Requirements Explorer
Climate change reporting is critical to ensure transparency of the UNFCCC system and builds trust among Parties. During the reporting process, countries follow expertly negotiated guidance, which has evolved over time, that specifies what data and information to collect and how to prepare different reports. This tool is intended to guide users in understanding the differences across UN Climate Change reporting requirements. With this tool, you may explore guidance for Annex I GHG Inventories, Biennial Reports (BRs), Biennial Transparency Reports (BTRs), Biennial Update Reports (BURs), and National Communications.
Note: The tool is not a substitute for the legal decisions reached under the Conference of Parties (COP) or the Conference of Parties serving as the Meeting of the Parties to the Paris Agreement (CMA).
