Much is still unknown about the impact of ammonia pollution, but rising emission rates concern scientists. The level of ammonia in the atmosphere was more than twice as large in 2010 as it was in 1940. [8] Ammonia is now recognized by many countries as a major pollutant and some have begun taking steps to limit their emissions. [7]
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
Annex 2 - Maximum allowable emissions (emission ceilings) [6] are adopted for 2010 for sulphur, nitrogen oxides (NO x), Volatile Organic Compounds (VOCs) and ammonia (NH 3). The selection of the specific emission levels (in tons/year) were based on the predicted effects of the pollutants and the pollutant control options and costs.
Making ammonia produces almost 2% of global carbon dioxide emissions.
