Figure Trend in NO2 and NOX annual mean concentrations (2001–2010) per station type (top); percentage frequency distribution of estimated annual change of NO2 annual mean concentrations at urban stations and at traffic stations (bottom)
All stations in EU Member States, with at least 75 % data coverage for at least eight years were included in the analysis. Concentrations per station type are given in μg/m3. In the top two diagrams a geographical bias exists towards central Europe where there is a higher density of stations. In the percentage frequency distribution graphs, closed bars denote stations showing a statistically significant trend, open bars denote stations with a non-significant trend. Statistically significant trends (level of significance 0.1) are calculated by applying the Mann-Kendall test. The applied method is described in de Leeuw, 2012.

Figure Emission trends of nitrogen oxides (EEA member countries, EU-27 Member States)
The 'with measures' (WM) projections reported by Member States take into account currently implemented and adopted policies and measures. Where countries have instead reported 'business as usual' or 'current legislation' projections, it is assumed for comparison purposes that these are equivalent to a WM projection. The 'with additional measures' projections reported by Member States take into account additional future planned policies and measures but which are not yet implemented.

Indicator Assessment chemical/x-pdb Emissions of acidifying substances (CSI 001/APE 007) - Assessment published Oct 2010
Emissions of acidifying pollutants (nitrogen oxides (NO X ), sulphur oxides (SO 2 ) and ammonia (NH 3 ) have decreased significantly in most of the individual EEA member countries between 1990 and 2008. Emissions of SO 2 have decreased by 74 %, NO X by 34 % and NH 3 emissions by 24 % since 1990. The EU-27 is on track to meet its overall target to reduce emissions of SO 2 and NH 3 as specified by the EU's NEC Directive (NECD). However a large number of individual Member States, and the EU as a whole, anticipate missing the 2010 emission ceilings set for NO X in the NECD, Of the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), both Liechtenstein and Norway also reported NO X emissions in 2008 that were substantially higher than their respective 2010 ceilings.

Indicator Assessment chemical/x-pdb Emissions of primary PM2.5 and PM10 particulate matter (CSI 003/APE 009) - Assessment published Oct 2010
Total emissions of primary PM10 particulate matter have reduced by 21% across the EEA-32 region between 1990 and 2008, driven by a 29% reduction in emissions of the fine particulate matter (PM2.5) fraction; emissions of particulates between 2.5 and 10 µm have risen slightly over the same period. Of this reduction in PM10 emissions, 48% has taken place in the 'Energy Production and Distribution' sector due to the fuel-switching from coal to natural gas for electricity generation and improvements in the performance of pollution abatement equipment installed at industrial facilities.

Indicator Assessment chemical/x-pdb Emissions of ozone precursors (CSI 002/APE 008) - Assessment published Oct 2010
Emissions of all ground-level ozone precursor pollutants have decreased across the EEA-32 region between 1990 and 2008; nitrogen oxides (NO X ) by 34%, non-methane volatile organic compounds (NMVOCs) by 45%, carbon monoxide (CO) by 56% and methane (CH 4 ) by 26%. This decrease has been achieved mainly as a result of the introduction of catalytic converters for vehicles. These changes have significantly reduced emissions of NO X and CO from the road transport sector, the main source of ozone precursor emissions. The EU-27 is still some way from meeting its 2010 target to reduce emissions of NO X , one of the two ozone precursors (NO X and NMVOC) for which emission limits exist under the EU's NEC Directive (NECD). Whilst total NMVOC emissions in the EU-27 were below the NECD limit in 2008, a number of individual Member States anticipate missing their ceilings for one or either of these two pollutants. Of the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), all three countries reported NMVOC emissions in 2008 that were lower than their respective 2010 ceilings. However both Liechtenstein and Norway reported NO x emissions in 2008 that were substantially higher than their respective 2010 ceilings.

Publication Impact of selected policy measures on Europe's air quality
The main objective of the present study is to analyse and quantify the effects that certain past policy measures in the road transport and industrial combustion facilities have had on the magnitude of air pollutant emissions and subsequent air quality in Europe. The policies selected are the Euro emission standards for road vehicles and the EU directives on Integrated Pollution Prevention and Control (IPPC) and large combustion plants (LCP).

Figure Emission trends of nitrogen oxides (EEA member countries, EU-27 Member States)
This chart shows past emission trends of nitrogen oxides in the EEA-32 and EU-27 group of countries. In addition - for the EU-27 - the 2010 NECD and 2020 Gothenburg target paths and emission ceilings are shown.
