Effects of Present and Future Controls of Ammonia Emissions in Europe
Abstract
Emissions of ammonia are responsible for a large portion of the particle formation in Europe and for the exceedances of critical loads of eutrophication. Emissions of sulphur, NOx and ammonia have decreased in most European countries from year 2005 to present, and further reductions are expected by 2030. However, the reductions in ammonia emissions have so far been smaller than for sulphur and NOx, and this mismatch in emission reductions is expected to continue until 2030. In combination, secondary PM2.5 particles are formed from these three species, either as ammonium sulphate or ammonium nitrate. Further reductions in ammonia emissions beyond the 2030 requirements could alleviate the health burden from fine particles and also reduce the deposition of nitrogen to vulnerable ecosystems.
