Distance-to-target graph for the CO limit value, 2010: The graph shows the percentage frequency distribution of stations (on the y-axis) in the EU Member States versus the various concentration classes (on the x-axis, in mg/m3). The vertical line corresponds to the limit value set by the EU legislation.

Emission trends of ozone-precursor pollutants (EEA member countries, EU-27): This chart shows past emission trends of nitrogen oxides (NOx), non-methane volatile organic compunds (NMVOC), carbon monoxide (CO) and methane (CH4) in the EEA-32 and EU-27 group of countries. In addition - for the EU-27 - the aggregated Member State 2010 emission ceilings for NOx and NMVOC are shown.

Emission trends of ozone-precursor pollutants 1990-2010 (EEA member countries, EU-27): This chart shows past emission trends of nitrogen oxides (NOx), non-methane volatile organic compunds (NMVOC), carbon monoxide (CO) and methane (CH4) in the EEA-32 and EU-27 group of countries. In addition - for the EU-27 - the aggregated Member State 2010 and 2020 emission ceilings for NOx and NMVOC are shown.

Emissions of ozone precursors (CSI 002) - Assessment published Dec 2012: Emissions of the main ground-level ozone precursor pollutants have decreased across the EEA-32 region between 1990 and 2010; nitrogen oxides (NO X ) by 42%, non-methane volatile organic compounds (NMVOC) by 53%, carbon monoxide (CO) by 61%, and methane (CH 4 ) by 32%. This decrease has been achieved mainly as a result of the introduction of catalytic converters for vehicles, which has significantly reduced emissions of NO X and CO from the road transport sector, the main source of ozone precursor emissions. The EU-27 as a whole has not met 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 2010, a number of individual Member States did not meet their ceilings for one or both of these two pollutants. Of the three non-EU countries having emission ceilings for 2010 set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), all reported NMVOC emissions in 2010 that were lower than their respective ceilings, however Liechtenstein and Norway reported NO X emissions higher than their ceiling for 2010.

Emissions of ozone precursors (CSI 002) - Assessment published Dec 2011: Emissions of the main ground-level ozone precursor pollutants have decreased across the EEA-32 region between 1990 and 2009; nitrogen oxides (NO X ) by 41%, non-methane volatile organic compounds (NMVOCs) by 51%, carbon monoxide (CO) by 61%, and methane (CH 4 ) by 27%. 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 National Emissions Ceiling Directive (NECD). Whilst total NMVOC emissions in the EU-27 were below the NECD limit in 2009, 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 for 2010 set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), all three countries reported NMVOC emissions in 2009 that were lower than their respective 2010 ceilings. However both Liechtenstein and Norway reported NO X emissions in 2009 that were substantially higher than their respective 2010 ceilings.

Emissions of ozone precursors (CSI 002) - 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.

European Community emission inventory report 1990-2007 under the UNECE Convention on Long-range Transboundary Air Pollution (LRTAP): This document is the European Union emission inventory report under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP). It includes information on the formal institutional arrangements that underpin the European Union's emission inventory, emission trends for the EU‑27 and Member States, and the contribution of important individual emission sources to total emissions, sector group emission trends for key pollutants, information on recalculations and future planned improvements.
