Air emissions data provide an analysis of air pollutants broken down by emission type and industry. It is an important topic within the UK Environmental Accounts.
Emissions are measured using a variety of methods dependant on the availability of data. These methods include directly measured point source emissions, such as those recorded by road side measuring instruments. Emissions are also estimated using conversion factors which link fuel use with its associated emissions. In other circumstances emissions data may be modelled using information from economic supply-use and input-output tables.
Estimates are updated annually each spring to include the most recent data published in the National Atmospheric Emissions Inventory (NAEI) and the Greenhouse Gas Emissions Inventory (GHGI). The data are compiled by contractors AEA Energy and Environment.
Air emissions data are used to provide information for policy makers and analysts. The main users in government include the Department for Environment, Food and Rural Affairs (Defra) and the Environment Agency. Outside government, research organisations and academia use the data for work on environmental impacts and sustainable development.
The air emissions data are compiled in accordance with SEEA 2003 which closely follows national accounting standards set out in the United Nations, System of National Accounts 1993 (SNA 93).
