Methodology

The UK National Atmospheric Emissions Inventory (NAEI) is developed and maintained by Ricardo-AEA, in collaboration with Aether, CEH, AMEC and SKM Enviros and is funded by the Department of Energy and Climate Change (DECC), Department for Environment, Food and Rural Affairs (Defra), the Welsh Government, the Scottish Government and the Department of Environment, Northern Ireland.

The NAEI is made up of the Greenhouse Gas Inventory (GHGI) and the Air Quality Pollutant Inventory (AQPI). To deliver these estimates, the GHG inventory team at Ricardo-AEA collect and analyse information from a wide range of sources – from national energy statistics through to data collected from individual industrial plants.
