This report compiles recent literature on ammonia (NH3) emission factors for application in the United States. Most of the recent research supports acid deposition studies in the European community (specifically, the Netherlands, Great Britain, and Scandinavia) but some research has been conducted in Australia. The majority of NH3 emissions in current inventories, up to 90% or more of anthropogenic emissions, originates from livestock wastes with fertilizer applications providing a significant proportion. Some inventories exclude industrial emissions entirely because they are insignificant relative to agricultural sources. Global climate change research indicates that undisturbed soils and biomass burning may also have significant emissions, up to half of the global NH3 budget.
