Ammonia emissions from agriculture

The indicator measures the amount of ammonia (NH3) emissions as a result of the agricultural production. This comprises manure management, inorganic N-fertilizers and animal manure applied to soil as well as urine and dung deposited by grazing animals. This definition is in line with the CAP indicator C46. The EU inventory on air pollution compiled by the European Environment Agency (EEA) under the Convention on Long-range Transboundary Air Pollution (LRTAP Convention) is fully consistent with national air pollution inventories compiled by the EU Member States. Ammonia emissions per hectare are calculated using the total utilised agricultural area (UAA) of the relevant year as denominator. Data on the UAA stem from Eurostat’s annual crop statistics.
