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 33% across the EEA member countries between 1990 and 2002, mainly as a result of the introduction of catalysts in new cars.

Key assessment

Total emissions of ozone precursors were reduced by 33 % across the EEA member countries between 1990 and 2002. For the EU-15 countries, emissions were reduced by 35 %.

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 10 % and 65 % 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 (38 % of total weighted emissions) and nitrogen oxides (48 % of total weighted emissions) contributed the most to the formation of tropospheric ozone in 2002. Carbon monoxide and methane contributed 13 % and 1 % respectively. The emissions of NOx and NMVOC were reduced significantly between 1990 and 2002, contributing 37 % and 44 % respectively of the total reduction in precursor emissions.

In the EU-10 (1), total ozone precursor emissions were reduced by 42 % between 1990 and 2002. Emissions of non-methane volatile organic compounds (32 % 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 2002.

Specific assessment

In both the EU-15 and EU-10, transport is the dominant source of ozone precursors. In 2002, transport contributed to 48% of total EU-15 emissions, with emissions from this sector contributing 65% of the total reduction of ozone precursor emissions between 1990 and 2002. Other important EU-15 emission sources in 2002 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 10% 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 40% of total TOFP-weighted emissions in 2002. Other significant emission sources in the EU-10 include commercial and domestic combustion processes (13% of total emissions), other non-energy (8%) and energy industries (13%). 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 14%, 25% and 26% of total reduction of ozone precursor emissions, respectively.
