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

Key messages

Emissions of ozone-forming gases (ground-level ozone precursors) were reduced by 36% across the EEA member countries between 1990 and 2004, mainly as a result of the introduction of catalysts in new cars.

Key assessment

Total emissions of ozone precursors were reduced by 36 % across the EEA-32 member countries between 1990 and 2004. For the EU-15 countries, emissions were reduced by 39 %.

Emission reductions in the EU-15 since 1990 are due mainly to the further introduction of catalytic converters for cars and increased penetration of diesel, but also as a result of the implementation of the solvents directive in industrial processes. Emissions from the energy and transport sectors have both been significantly reduced, and contributed 9 % and 64 % respectively of the total reduction in weighted ozone precursor emissions. Emission reductions of the ozone precursors covered by the national emission ceilings directive (non-methane volatile organic compounds, NMVOCs, and nitrogen oxides, NOx) have resulted in the EU-15 being on track to reaching the overall target for reducing these emissions in 2010.

Emissions of non-methane volatile organic compounds (44 % of total weighted emissions) and nitrogen oxides (36 % of total weighted emissions) contributed the most to the formation of tropospheric ozone in 2004. Carbon monoxide and methane contributed 20 % and 1 % respectively. The emissions of NOx and NMVOC were reduced significantly between 1990 and 2004, contributing 31 % and 44 % respectively of the total reduction in precursor emissions.

In the EU-10 (1), total ozone precursor emissions were reduced by 40 % between 1990 and 2004. Emissions of non-methane volatile organic compounds (35 % of the total) and nitrogen oxides (51 % of the total) were the most significant pollutants contributing to the formation of tropospheric ozone in EU-10 countries in 2004.

Specific assessment

In both the EU-15 and EU-10, transport is the dominant source of ozone precursors. In 2004, transport contributed to 45% of total EU-15 emissions, with emissions from this sector contributing 66% of the total reduction of ozone precursor emissions between 1990 and 2004. Other important EU-15 emission sources in 2004 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, contributing 9% of the total reduction of ozone precursor emissions. Emission reductions that have occurred 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 Solvents Directive in industrial processes.

In the EU-10, transport is again the dominant source of ozone precursors and contributed 42% of total TOFP-weighted emissions in 2004. Other significant emission sources in the EU-10 include commercial and domestic combustion processes (13% of total emissions), other non-energy (10%) and energy industries (16%). As observed across the EU-15, the emission reductions observed are mainly due to further introduction of catalytic converters for cars and increased penetration of diesel, but also through the implementation of the Solvents Directive in industrial processes and reduction of fuel consumption. Emissions in the industry (processes), energy industry and transport sectors have all been significantly reduced, and contributed to 16%, 27% and 28% of total reduction of ozone precursor emissions, respectively.
