Austria’s Annual Air Emission Inventory 1990-2020.

The report on Austria’s Annual Air Emission Inventory 1990-2020, compiled by the Umweltbundesamt, provides a summary of Austria’s SO2, NOx, NH3, NMVOC and PM2.5 emissions for the years 1990 to 2020. The report includes information on emission trends and recalculations for the pollutants regulated in the NEC Directive performed from 1990 to 2020. Detailed descriptions will be provided in Austria’s Informative Inventory Report (IIR) 2022. The results of the calculations presented in the report show that NMVOC emissions increased by 2.3 kt (2.1 %) between 2019 and 2020. This was due to the increased use of disinfectants due to the pandemic. The emissions of the other pollutants decreased: emissions of sulphur dioxide (SO2) by 5.5 %, nitrogen oxide emissions (NOx) by 14.1 %, ammonia emissions (NH3) by 0.8 % and particulate matter (PM2.5) by 5.4 %.
