The NAEI is situated at the National Environmental Technology Centre, AEA Technology at Culham, Oxfordshire. The NAEI estimates national total emissions of a wide range of pollutants for each year since 1970. It also produces spatial emission maps of selected pollutants. This data will also contain some projections of future emissions of some pollutants. The pollutants can be roughly grouped according to their environmental inpacts.
Some pollutants can have a wide range of effects across different groups.
The pollutants considered are listed below. These are pollutants that have a global impact - the greenhouse effect. Estimates of emissions of the greenhouse gases are submitted under the Framework Convention on Climate Change.
