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.
