This webinar focuses on the “Quality Assurance (QA) of the National GHG Inventory Management System and National GHG Inventories”. It especially looks at the QA activity on the national GHG inventory management system and GHG inventories organized by the UNFCCC Secretariat upon request from developing countries, with the support of FAO.  Participants will learn more about the QA and Quality Control (QC) within the national GHG inventory management system; the UNFCCC Secretariat's QA activity; and how developing countries can participate in the latter. The webinar's main objectives are to:  Highlight the importance of the QA/QC as an integral part of a national GHG inventory management system. Present the Enhanced Transparency Framework (ETF) requirements for developing and maintaining a national QA/QC system - including developing an improvement plan. Present the QA activity organized by the UNFCCC Secretariat upon request from developing countries - including its goals and benefits for countries and how they can participate. Present “country perspectives” on the QA activity based on the feedback from countries that have already undertaken the UNFCCC Secretariat’s QA. Stimulate interaction between countries on their QA systems, their preparedness level, and their challenges. PLEASE NOTE: The main target audience of the webinar are experts and practitioners from CBIT-AFOLU countries (global project and national CBIT). Additional spaces are available for experts joining the FAO Transparency in agriculture and land use sectors network, based on their expressed interest. Relevant materials will be shared with participants before the webinar to prepare for the discussions.
