-   * Air scrubber systems in 75 per cent of the agricultural operations regulated under IED (permitted after type of procedure G in the 4<sup>th</sup> BImSchV), 25 per cent of the agricultural IED operations reduce 40 per cent of emissions through further system-integrated measures in housing.\\ Air scrubber systems for pigs reduce the NH<sub>3</sub> emissions in the stable by 80 per cent on average; this percentage is retained. A reduction rate of 70 per cent is assumed for air scrubber systems for poultry. It should be noted that the reductions were not calculated for turkeys, as these are excluded from the requirement in the Technical Instructions on Air Quality Control (TA-Luft).\\ \\ __Assumptions to model the mitigation potential in 2030:__ For pigs and poultry, the mean reduction performance from air scrubber systems and “further system-integrated measures” was calculated (pigs: 0.75 * 80 % + 0.25 * 40 % = 70 %; poultry: 0.75 * 70 % + 0.25 * 40% = 62.5 %) and with this the emissions of the animals in agricultural IED operations are calculated as if they were air scrubber systems with a correspondingly lower output.\\ \\ Calculated additional emission reduction in kt NH<sub>3</sub>: 13.61\\ Calculated cumulative emission reduction in kt NH<sub>3</sub>: 16.77+   * Air scrubber systems in 75 per cent of the agricultural operations regulated under IED (permitted after type of procedure G in the 4<sup>th</sup> BImSchV), 25 per cent of the agricultural IED operations reduce 40 per cent of emissions through further system-integrated measures in housing.\\ Air scrubber systems for pigs reduce the NH<sub>3</sub> emissions in the stable by 80 per cent on average; this percentage is retained.
