Key policy question: What progress is being made in reducing emissions of ozone precursors across Europe?

Key messages

Aggregated emissions of ozone-forming gases (ground-level ozone precursors - CH4, CO, NMVOC and NOx) were reduced by 38% across the EEA member countries between 1990 and 2005, mainly as a result of the increased use of catalytic converters and to a lesser extent to a switch from petrol cars to diesel cars. Together these changes have significantly reduced emissions of NOx and CO from vehicles, an important source of ozone precursor emissions (Figure 1).

Emissions in the EU-15 Member States decreased by 41% since 1990 (Figure 2), from 36 981 kt to 21 760 kt.

Between 1990 and 2005 emission of ozone precursors in the new EU-12 Member States declined significantly from 9 136 kt to 5 715 kt, a reduction of 37% (Figure 3).

The EU-15 and new EU-12 are unlikely to meet their aggregated 2010 NECD target for the two ozone precursors NOx and NMVOCs.

Key assessment

Total emissions of ozone precursors were reduced by 38% across the EEA-32 member countries between 1990 and 2005.

For the EU-15 Member States, emissions were reduced by 41%. Emission reductions in the EU-15 since 1990 are mainly due to the further introduction of catalytic converters for cars and increased penetration of diesel, but also as a result of, for example, the implementation of the Solvent Emissions Directive in industrial processes.

A large majority of the reduction of ozone precursors occurred in the road transport sector, while the next most important sector was energy industries (8%).

Emissions of nitrogen oxides (51% of total weighted emissions) and non-methane volatile organic compounds (36% of total weighted emissions) contributed the most to the formation of tropospheric ozone in 2005. Carbon monoxide and methane contributed 12% and 1%, respectively. However, emissions of NOx and NMVOC were reduced significantly between 1990 and 2005, contributing 33% and 47%, respectively, of the total reduction in precursor emissions.

In the new EU-12 [1], total ozone precursor emissions were reduced by 37% between 1990 and 2005. Emissions of non-methane volatile organic compounds (38% of the total) and nitrogen oxides (46% of the total) were the most significant pollutants contributing to the formation of tropospheric ozone in the new EU-12 Member States in 2005.

A recent study performed for the European Commission [2] indicates that 10 out of 23 EU-27 Member States (excluding Greece, Romania, Bulgaria and Luxembourg) predict that their 2010 emission estimates will be higher than their NECD target vaue for NOx and 2 out of 23 member States predict that they are unlikely to meet their NECD target for NMVOC in 2010 under implemented and planned policies and measures.

Emission reductions of the ozone precursors covered by the EU National Emission Ceilings Directive (non-methane volatile organic compounds NMVOCs, and nitrogen oxides NOx) have to be reduced further for the EU-15 to reach the overall target for reducing these emissions by 2010. Ten out of 13 EU-15 Member States indicated that they are unlikely to meet their NECD ceiling for NOx or NMVOC in 2010 [2] .

Within the new EU-12, nine of 10 Member States (excluding Bulgaria and Romania) are well on track to meeting their NECD targets for SO2 or NOx [2].

Specific assessment

In the EU-15, transport is the dominant source of ozone precursors. In 2005, transport contributed to 43% of total EU-15 emissions, with emissions from this sector contributing to 67% of the total reduction of ozone precursor emissions between 1990 and 2005 (Figure 8). Other important EU-15 emission sources in 2005 included commercial and domestic combustion and use of solvents in paint, glue and printing. After the transport sector, the sector responsible for the second largest absolute reduction was the energy industries sector due to the decline in coal use in favour of gas and electricity, contributing 8% of the total reduction of ozone precursor emissions. Emission reductions that have occured within the EU-15 region since 1990 are mainly due to the further introduction of catalytic converters for cars and increased penetration of diesel, but also as a result of the implementation of the Solvent Emissions Directive in industrial processes.

 

In the new EU-12 Member States, transport is again the dominant source of ozone precursors, contributing 33% of total TOFP-weighted emissions in 2005 (Figure 9). Other significant emission sources in the new EU-12 include commercial and domestic combustion processes (15% of total emissions), other non-energy (14%) and engery industries (14%). As observed across the EU-15, the emission reductions are also mainly due to further introduction of catalytic converters for cars and increased penetration of diesel, but also due to the implementation of the Solvent Emissions Directive in industrial processes and reduction of fuel consumption. Emissions in the industry (processes) and energy sectors have all been significantly reduced, and contributed to 16% and 24% of the total reduction of ozone precursor emissions, respectively.
