The UK data are used for International and European reporting obligations. UK emissions data are reported to the UNFCCC (GHG), UNECE & EMEP (Air Quality) and NECR (Air Quality).
The UK level datasets are produced on a 'by source' and 'end user' basis for both Air Pollutants and Greenhouse Gases. All of the international submissions are on a ‘by source' basis. The NAEI also produces the following inventories on an 'end user' basis:
- National inventory – both GHG and AQ
- Devolved Administration – GHG only
- LAGHG - GHG only
'By source' refers to emissions being attributed to the sector that emits them directly while 'end user' refers to emissions being reallocated from the fuel producers to fuel users. More information on this can be found in the methodology section.
Accredited Official Statistics
Outputs from the NAEI have been classified as Accredited Official Statistics which provides an assurance that statistics have been produced to the highest professional standards as set out in the UK Statistics Authority's Code of Practice for Statistics.
The Local and Regional GHG emission estimates are also classified as Accredited Official Statistics.
