The thesis considers trends in European emissions over the past several decades, the quality of these emission inventories and the environmental impact of the emission trends. The focus is on sulfur dioxide and nitrogen oxides, although other chemical species are included as well. Sulfur and nitrogen emissions are of interest because these compounds have been highly regulated over the past years.
