Consistency of air pollutants data A10 UK NIR 2023 (Issue 1) Ricardo Energy & Environment Page 1153 ANNEX 10: Reporting on consistency of the reported data on air pollutants The total emissions for all pollutants agree to within 0.2%.
Discrepancies at a category level relate primarily to differences in allocation between the energy and IPPU sectors (e.g. for lubricants), and between the waste and ‘Other’ sectors (e.g.
accidental fires, bonfires and non- Differences in the totals relate only to differences in reporting for aviation (which is a subset of 1A3, and the total difference for 1A3 includes the impact of differing allocations for lubricants). For aviation, all Take Off and Landing (TOL) emissions (domestic and international) are included for NECR and CLRTAP, and all domestic emissions (TOL and cruise) are included for For the full analysis, please see the ‘Annex_Air_Pollutant_Consistency_2023_Submission.xlsx’
