-In 2024 the agricultural sector emitted 484.0 Gg of NH<sub>3</sub>, 98,0  Gg of NO<sub>x</sub>, 300,6 Gg of NMVOC, 60,4 Gg of TSP, 34,7 Gg of PM<sub>10</sub> and 5.3 Gg of PM<sub>2.5</sub> and 0.30 kg HCB. The trend from 1990 onwards is shown in the graph below. The sharp decrease of emissions from 1990 to 1991 is due to a reduction of livestock population in the New Länder (former GDR) following the German reunification. The increase of NH<sub>3</sub> emissions since 2005 is mostly due to the expansion of anaerobic digestion of energy crops, especially the application of the digestion residues. This emission source also affects NO<sub>x</sub> emissions. The decrease of NH<sub>3</sub> emissions since 2015 is mostly due to a decline in the amounts of mineral fertilizer sold and stricter regulations concerning application of urea fertilizers, as well as declining livestock numbers Further details concerning trends can be found in Vos et al. (2026) chapter “Emissions results submission 2026”. +In 2024 the agricultural sector emitted 484.0 Gg of NH<sub>3</sub>, 98,0  Gg of NO<sub>x</sub>, 300,6 Gg of NMVOC, 60,4 Gg of TSP, 34,7 Gg of PM<sub>10</sub> and 5.3 Gg of PM<sub>2.5</sub> and 0.53 kg HCB.

-As depicted in the diagram below, in 2023 92.6 % of Germany’s total NH<sub>3</sub> emissions derived from the agricultural sector, while nitric oxides reported as NO<sub>x</sub> contributed 11.8 % and NMVOC 30.9 % to the total NO<sub>x</sub> and NMVOC emissions of Germany. Regarding the emissions of PM<sub>2.5</sub>, PM<sub>10</sub> and TSP the agricultural sector contributed 7.0 % (PM<sub>2.5</sub>), 19.5 % (PM<sub>10</sub>) and 18.3 % (TSP) to the national particle emissions. HCB emissions of pesticide use contributed 7.6 % to the total German emissions. +As depicted in the diagram below, in 2024 91.7 % of Germany’s total NH<sub>3</sub> emissions derived from the agricultural sector, while nitric oxides reported as NO<sub>x</sub> contributed 12.1 % and NMVOC 31.5 % to the total NO<sub>x</sub> and NMVOC emissions of Germany.

-  * use of urease inhibitors: for urea fertilizer the German fertilizer ordinance prescribes the use of urease inhibitors or the direct incorporation into the soil from 2020 onwards. The NH<sub>3</sub> emission factor for urea fertilizers is therefore reduced by 70% from 2020 onwards for the direct incorporation, according to Bittman et al. (2014, Table 15)((Bittman, S., Dedina, M., Howard C.M., Oenema, O., Sutton, M.A., (eds) (2014): Options for Ammonia Mitigation. Guidance from the UNECE task Force on Reactive Nitrogen.
