ENV01 - Emissions of air pollutants
Source: gov.uk (2025-03-13)

Annual update to tables on emissions of important air pollutants in the UK.

This data was revised on March 13th 2025 to apply the latest, improved domestic combustion methodology across all sources. This correction has impacted domestic combustion emissions across the time series causing a substantial reduction to sulphur dioxide emissions and a minor increase to NMVOC emissions.

This publication covers UK emissions of sulphur dioxide, nitrogen oxides, non-methane volatile organic compounds, ammonia and particulate matter.

The estimation methodology is regularly developed to take account of new emission factors and modelling methods. This means the whole time series is revised annually. The figures given in this document and the supporting dataset show the revised estimates.
