Annual update to tables on emissions of important air pollutants in the UK.
This dataset covers UK emissions of sulphur dioxide (SO2), nitrogen oxides (NOx), non methane volatile organic compounds (NMVOCs), ammonia (NH3) and particulate matter (PM10 and PM2.5).
Emission factors for PM2.5 have been updated to estimate the emissions levels for this pollutant in the National Atmospheric Emissions Inventory. This has led to a slight reduction in the pollutant emissions for the 1970-2015 time series. The scale of the revisions is minor and there is no impact on the overall trend which continues to be downwards. There is no impact on previous versions of the Statistic as these are wholly superseded each year; ongoing improvements to the estimation methodology mean the time series is often revised. The figures given in this document and the supporting dataset show the revised estimates. The next scheduled release of this National Statistic will be in December 2017.
