Emissions of the acidifying pollutants, nitrogen oxides (NO X ), sulphur oxides (SO X ) and ammonia (NH 3 ), have decreased significantly in most of the individual EEA member countries between 1990 and 2011. Emissions of SO X have decreased by 74%, NO X by 44% and NH 3 by 25% since 1990 within the EEA-33.
Data reported under the NECD indicates that in 2011 the EU-28 as a whole met its continuing obligation to maintain emissions of NO X , SO X and NH 3 below 2010 target as specified by the EU’s National Emissions Ceiling Directive (NECD). However, the EU-15 as a whole and seven individual Member States, all of which are in the EU-15 group, reported emissions in 2011 above their NECD emission ceilings for NO X . Four EU member states reported 2011 NH 3 emissions above the levels of their NECD ceilings, three of which are in the group of fifteen pre-2004 EU member states.
Three additional countries which are current EEA Member States have emission ceilings for 2010 under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland). Both Liechtenstein and Norway reported NO X and NH 3 emissions in 2011 that were higher than their respective 2010 ceilings.
