%0 Journal Article %J Atmospheric Environment %D 2001 %T A detailed ammonia emission inventory for Denmark %A Hutchings, N. J %A Sommer, S. G %A Andersen, J. M %A Asman, W. A. H %K EPNB %X This paper describes the method used to create an ammonia inventory for Denmark and presents the emission factors used and their justi"cation. The total Danish emission for 1996 was 92,700 t NH4-N, with agriculture accounting for nearly 99%. Emissions from animal manure accounted for 76% of agricultural emissions. We conclude that there will be a continued demand for inventories based on emission factors, despite their lack of physical and chemical realism, but that they will become more complex. This will place increased demands on the statistical information available and on the knowledge of the underlying science. %B Atmospheric Environment %V 35 %1 EPNB %0 Journal Article %J Agriculture, Ecosystems and Environment %D 2006 %T The development of the EMEP/CORINAIR Guidebook with respect to the emissions of different nitrogen and carbon species from animal production. %A Daemmgen, U %A Webb, J %K EPNB %X The reduction of emissions of air pollutants is subject of international conventions, which include reporting of emissions in accordance with guidelines or guidebooks provided. Within the Convention on the Long-range Transboundary Air Pollution, the Atmospheric Emission Inventory Guidebook describes the methodology. With respect to emissions from agricultural sources, in particular from animal husbandry, this guidebook at present undergoes major modifications: the calculation procedure making use of partial emission factors for the various sources of emissions (animal house, storage, manure application, etc.) is being replaced by a mass flow concept for both nitrogen and carbon species. The current state of the Guidebook, present activities to update it and future plans are described. The necessity to update both the Guidebook and the IPCC Guidelines as complementary tools to describe agricultural emissions and mass flows is emphasized. %B Agriculture, Ecosystems and Environment %V 112 %1 EPNB
