Austria’s Annual Air Emission Inventory 1990-2022.

Austria’s Annual Air Emission Inventory 1990-2022 provides an overview of national emissions of sulphur dioxide (SO2), nitrogen oxides (NOx), ammonia (NH3), non-methane volatile organic compounds (NMVOC) and particulate matter (PM2.5) for the years 1990 to 2022. Emission trends and recalculations of these air pollutants, regulated in the European NEC Directive, are described. The results show emission reductions for all pollutants between 2021 and 2022: SO2 declined by 0.9 %, NOx by 7.1 %, NMVOC by 7.4 %, NH3 by 1.7 %, and PM2.5 by 9.6 %. The reductions, except for NH3, were largely resulting from the households sector (1.A.4.b.1), where the milder winter and price changes on the energy market led to a significant decrease in household combustion for heat. The main reasons for reduced NH3 emissions were lower amounts of mineral fertilizer and the increased use of band spreading techniques. The 2022 emissions comply with national emission reduction commitments for all pollutants, except for NH3, which exceeded the target by 4%.奥地利1990-2022年年度空气排放清单（Austria’s Annual Air Emission Inventory 1990-2022）概述了1990至2022年间该国二氧化硫（sulphur dioxide, SO2）、氮氧化物（nitrogen oxides, NOx）、氨（ammonia, NH3）、非甲烷挥发性有机化合物（non-methane volatile organic compounds, NMVOC）以及细颗粒物（particulate matter, PM2.5）的国家排放情况。本数据集阐述了受欧盟《国家排放限额指令》（European NEC Directive）监管的上述大气污染物的排放趋势与重新核算结果。数据显示，2021年至2022年间所有污染物排放量均有所下降：二氧化硫下降0.9%，氮氧化物下降7.1%，非甲烷挥发性有机化合物下降7.4%，氨下降1.7%，细颗粒物PM2.5下降9.6%。除氨之外，其余污染物的减排主要源于居民生活部门（1.A.4.b.1）——暖冬气候与能源市场价格变动导致居民家用供热燃料燃烧量大幅减少。氨排放量下降的主要原因是矿物肥料使用量减少以及条带施肥技术的推广应用。2022年各项污染物排放量均符合国家减排承诺，仅氨排放量超出目标值4%。
