The purpose of this template is to explain how to use the GHG data repository tool and provides tables to develop a national GHG inventory schedule and track progress with completing each template in the series. This template helps the National GHG Inventory Coordinator (NIC) initiate and manage inventory planning and provides a table to record due dates for key compilation stages. This template can facilitate GHG inventory planning for current (i.e., Biennial Update Report, National Communications) and future (i.e., Biennial Transparency Report, National Communications) reporting under the Enhanced Transparency Framework1 to the United Nations Framework Convention on Climate Change (UNFCCC). Under the Paris Agreement, the Enhanced Transparency Framework (ETF) established new common Modalities, Procedures, and Guidelines (MPGs) for reporting under Article 13. The MPGs are based on a set of guiding principles that allow for flexibility in reporting, in light of national circumstances, while promoting the consistency, completeness, and reliability of reports. The MPGs define the reporting information to be provided, the technical expert review methods, institutional arrangements, and a process by which nations inform the national community of progress toward their goals. The ETF provides built-in flexibility to those developing countries that need it, owing to their national capacities. Through the detailed guidance on the reporting, review, and consideration processes for the information to be submitted and by making these reports publicly available, the ETF will make it possible to track the progress made by each country. In this way, it will be possible to compare a country’s actions against its plans and ambitions as described in its Nationally Determined Contributions (NDCs)2.
