Scotland’s Chief Statistician has announced the publication of a report on emissions of air pollutants in 2017.
The main findings are:
- Since 1990, there have been reductions in emissions for all pollutants, with decreases of 15% for ammonia, 63% for PM10, 65% for NMVOCs, 68% for PM2.5, 71% for nitrogen oxides, 84% for carbon monoxide, 96% for sulphur dioxide and 97% for lead.
- Scottish emissions accounted for 11% of the UK total of ammonia. The main source of Scottish emissions was agriculture, which was responsible for 92% of ammonia emissions.
- Scottish emissions accounted for 9% of UK PM10 emissions, with 32% of Scottish emissions coming from combustion, 26% from industrial processes, 18% from agriculture and 17% from transport sources.
- Scottish emissions accounted for 17% of UK NMVOCS emissions. Industrial processes, mainly breweries and distilleries, accounted for 49% of Scottish emissions, solvents and other product use 19% and fugitive emissions from fuels accounted for 14%.
- Scottish emissions accounted for 8% of UK PM2.5 emissions, with 57% of Scottish emissions came from combustion and 22% from transport sources.
- Scottish emissions accounted for 11% of UK nitrogen oxide emissions. Transport sources accounted for 51% of Scottish emissions, combustion was 31% and energy industries ran to 13%.
- Scottish emissions accounted for 7% of UK carbon monoxide (CO) emissions. Combustion accounted for 68% of Scottish emissions and transport sources ran to 26%.
- Scottish emissions of sulphur dioxide accounted for 8% of UK emissions, with 38% of Scottish emissions coming from combustion, 37% from power generation and 18% from transport sources.
- Scottish lead emissions accounted for 6% of UK emissions. Transport accounted for 51% of Scottish emissions, combustion 24% and industrial processes 20%.
