Pigs: In the case of air scrubbing systems in pig housings, a distinction between certified and non-certified systems has been introduced in accordance with improved data availability for Submission 2020: For certified systems, removal of NH3 and particulate matter is taken into account, while non-certified systems are assumed to only remove particulate matter reliably. | + | 8) All pigs except boars: Update of activity data of air scrubbing systems in pig housings |

- | 15. The emissions of TSP and PM from agricultural soils differ slightly from the corresponding emissions in Submission 2019. These changes are due to the fact that for the first time the acreage of strawberries and cereals for whole plant harvesting were considered. The differences to the submission 2019 are between 0.05% (1990) and 1.1% (2015). | ||

Once emission calculations with the German inventory model GAS-EM are completed for a specific submission, activity data (AD) and implied emission factors (IEFs) are transferred to the CSE database (Central System of Emissions) to be used to calculate the respective emissions within the CSE. These CSE emission results are then cross-checked with the emission results obtained by GAS-EM. | Once emission calculations with the German inventory model GAS-EM are completed for a specific submission, activity data (AD) and implied emission factors (IEFs) are transferred to the CSE database (Central System of Emissions) to be used to calculate the respective emissions within the CSE.
