-Uncertainty in the NH<sub>3</sub> emission national total is moderate and mainly caused by agriculture sources, in particular [[sector:agriculture:agricultural_soils:start|3.D.a.2.a - Animal manure applied to soils]]. [[sector:agriculture:manure_management:start|3.B.3 - Manure management - Swine]], [[sector:agriculture:manure_management:start|3.B - Manure Management - Dairy cattle]] and [[sector:agriculture:agricultural_soils:start|3.D.a.1 - Inorganic N-fertilizers]] do also play significant roles. The national total has a 95% confidence interval of about -8.9% to +9.5% in 2023, which amounts to about 105kt of NH<sub>3</sub>. You can drive your own analysis with the numbers found in the {{general:uncertainty_evaluation:uncertainty_details_nh3.xlsx | spreadsheet file}} attached.+Uncertainty in the NH<sub>3</sub> emission national total is moderate and mainly caused by agriculture sources, in particular [[sector:agriculture:agricultural_soils:start|3.D.a.2.a - Animal manure applied to soils]].

-PM<sub>2.5</sub> emissions are associated with high uncertainties. The national total has a 95% confidence interval of about -17.5% to +20.8% in 2023, which amounts to about 30kt of PM<sub>2.5</sub>. Three sectors contribute the bulk of these errors: [[sector:energy:fuel_combustion:small_combustion:stationary_small_combustion:residential|1.A.4.b.i - Residential: Stationary Combustion]], [[sector:ippu:bulk_products:handling_of_bulk_products:start|2.L - Other production, consumption, storage, transportation or handling of bulk products]] and [[sector:agriculture:agricultural_soils:start|3.D.3 - Farm-level Agricultural Operations]]. Germany is also one of the few countries that reports abrasion under [[sector:energy:fuel_combustion:transport:railways:start|1.A.3.c - Transport: Railways]], adding noticeably to both emission values and uncertainties.

 There is currently no uncertainty assessment for additional air pollutants, heavy metals and POPs. Germany seeks to expand the list of pollutants covered as resources allow. There is currently no uncertainty assessment for additional air pollutants, heavy metals and POPs.
