The NCC approves the annual inventory of greenhouse gas emissions that Belgium submits to the European Commission (Articles 7 and 8 of Regulation (EU) No 525/2013) and to the UNFCCC Secretariat under the United Nations Framework Convention and its Protocols.

This national inventory is compiled from the three regional emission inventories prepared within the regional agencies (AwAC for the Walloon region, VMM for the Flemish region, Brussels-Environment for the Brussels region) sous under the supervision of the Emissions Working Group of the Coordination Committee for International Environmental Policy (CCIEP).

The National Inventory Compiler (NIC) is currently Olivier Biernaux who is working in the Belgian Interregional Environment Agency (IRCEL-CELINE).

Further details on the exact modalities of the national inventory are available in the National Inventory System (NIS) and in the National Inventory Report (NIR), which are the constituent elements of the inventory submission under the heading Reports.
