Sulphur dioxide SO2 emissions (APE 001) - Assessment published Dec 2012
-
EEA-32 emissions of sulphur oxides (SO X ) have decreased by 75% between 1990 and 2010. In 2010, the most significant sectoral source of SO X emissions was 'Energy production and distribution' (57% of total emissions), followed by emissions occurring from 'Energy use in industry' (21%) and in the 'Commercial, institutional and households' (14%) sector.
The reduction in emissions since 1990 has been achieved as a result of a combination of measures, including fuel-switching in energy-related sectors away from high-sulphur solid and liquid fuels to low-sulphur fuels such as natural gas, the fitting of flue gas desulphurisation abatement technology in industrial facilities and the impact of European Union directives relating to the sulphur content of certain liquid fuels.
All of the EU-27 Member States have reduced their national SO X emissions below the level of the 2010 emission ceilings set in the National Emission Ceilings Directive (NECD) [1] . Emissions in 2010 for the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland) were also below the level of their respective 2010 ceilings.
Environmental context: Sulphur dioxide is emitted when fuels containing sulphur are combusted. It is a pollutant which contributes to acid deposition which in turn can lead to changes occurring in soil and water quality. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. SO 2 emissions also aggravate asthma conditions and can reduce lung function and inflame the respiratory tract, and contribute as a secondary particulate pollutant to formation of particulate matter in the atmosphere, an important air pollutant in terms of its adverse impact on human health. Further, the formation of sulphate particles in the atmosphere after its release results in reflection of solar radiation, which leads to net cooling of the atmosphere.

Ammonia (NH3) emissions (APE 003) - Assessment published Dec 2012
-
EEA-32 emissions of NH 3 have declined by 28% between the years 1990 and 2010. Agriculture was responsible for 94% of NH 3 emissions in 2010.
The reduction in emissions within the agricultural sector is primarily due to a reduction in livestock numbers (especially cattle) since 1990, changes in the handling and management of organic manures and from the decreased use of nitrogenous fertilisers. The reductions achieved in the agricultural sector have been marginally offset by the increase in annual emissions over this period in the road-transport sector, and to a lesser extent the 'Solvent and product use' and 'Non-road transport' sectors.
All but two of the EU-27 Member States reported 2010 national NH 3 emissions under NECD below the level of the 2010 emission ceilings set in the National Emission Ceilings Directive (NECD) [1] . Emissions in 2010 for two of the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland) were also below the level of the respective 2010 ceilings.
Environmental context: NH 3 contributes to acid deposition and eutrophication. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. Eutrophication can lead to severe reductions in water quality with subsequent impacts including decreased biodiversity, changes in species composition and dominance, and toxicity effects. NH 3 also contributes to the formation of secondary particulate aerosols, an important air pollutant due to its adverse impacts on human health.
[1] Emissions data reported by EU member states under NECD is used for comparison with NECD ceilings, and data reported under CLRTAP is used for all other calculations unless otherwise stated. 2010 emissions reported under NECD in 2012 by 11 member states differed from that reported under CLRTAP.

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.

Floods and health (CLIM 046) - Assessment published Nov 2012
-
River and coastal flooding affect millions of people in Europe each year. They affect human health through drowning, heart attacks, injuries, infections, psychosocial consequences, and health effects of chemical hazards as well as disruption of services.
Observed increases in heavy precipitation and extreme coastal high-water events have led to more river and coastal flooding in many European regions.
Increases in health risks associated with river and coastal flooding are projected in many regions of Europe due to projected increases in extreme precipitation events and sea level.

Non-methane volatile organic compounds (NMVOC) emissions (APE 004) - Assessment published Dec 2012
-
EEA-32 emissions of non-methane volatile organic compounds (NMVOCs) have decreased by 53% since 1990. In 2010, the most significant sources of NMVOC emissions were 'Solvent and product use' (42%), comprising activities such as paint application, dry-cleaning and other use of solvents, followed by 'Commercial, institutional and households' (18%).
The decline in emissions since 1990 has primarily been due to reductions achieved in the road transport sector due to the introduction of vehicle catalytic converters and carbon canisters on petrol cars for evaporative emission control, driven by tighter vehicle emission standards, combined with limits on the maximum volatility of petrol that can be sold in EU Member States, as specified in fuel quality directives. The reductions in NMVOC emissions have been enhanced by the switching from petrol to diesel cars in some EU countries, and changes in the 'Solvents and product use' sector as a result of the introduction of legislative measures limiting the use and emissions of solvents.
The majority of EU-27 Member States have reduced emissions since 1990 in line with their obligations under the National Emission Ceilings Directive (NECD), however two Member States have not met their ceilings (Germany and Spain) [1] . Emissions in 2010 for the three non-EU countries which have emission ceilings for 2010 set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland) were all well below their respective ceilings.
Environmental context: Non-methane volatile organic compounds (NMVOCs) are a collection of organic compounds that differ widely in their chemical composition but display similar behaviour in the atmosphere. NMVOCs are emitted into the atmosphere from a large number of sources including combustion activities, solvent use and production processes. Biogenic NMVOC are emitted by vegetation, with amounts dependent on the species and on temperature. NMVOCs contribute to the formation of ground-level (tropospheric) ozone, and certain species such as benzene and 1,3 butadiene are directly hazardous to human health. Quantifying the emissions of total NMVOC provides an indicator of the emissions of the most hazardous NMVOCs.

Emissions of primary particulate matter and secondary particulate matter precursors (CSI 003) - Assessment published Dec 2012
-
Total emissions of primary sub-10µm particulate matter (PM 10 ) have reduced by 26% across the EEA-32 region between 1990 and 2010, driven by a 28% reduction in emissions of the fine particulate matter (PM 2.5 ) fraction. Emissions of particulates between 2.5 and 10 µm have reduced by 21% over the same period; the difference of this trend to that of PM 2.5 is due to significantly increased emissions in the 2.5 to 10 µm fraction from 'Road transport' and 'Agriculture' (of 50% and 15% respectively) since 1990.
Of this reduction in PM 10 emissions, 39% has taken place in the 'Energy Production and Distribution' sector due to factors including the fuel-switching from coal to natural gas for electricity generation and improvements in the performance of pollution abatement equipment installed at industrial facilities.

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.

In 2009, the most significant sources of NMVOC emissions were ‘Solvent and product use’ (36%) (comprising activities such as paint application, dry-cleaning and other use of solvents), followed by ‘Commercial, institutional and households’ (15%).
The decline in emissions since 1990 has primarily been due to reductions achieved in the road transport sector due to the introduction of vehicle catalytic converters and carbon canisters on petrol cars, for evaporative emission control driven by tighter vehicle emission standards, combined with limits on the maximum volatility of petrol that can be sold in EU Member States, as specified in fuel quality directives.

The EU-27 Member States have, in general, made good progress towards reducing emissions in line with their obligations under the National Emission Ceilings Directive (NECD). Twenty four Member States (Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Estonia, Finland, France, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Sweden and the United Kingdom) have already reduced their national NMVOC emissions below the level of the emission ceilings set in the NECD. However, two Member States (Denmark and Germany) reported 2009 emissions significantly above their respective emission ceilings and therefore require significant reductions to have been made in 2010 in order to comply with the NECD. Emissions in 2009 for the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland) were all well below their respective ceilings.

Nitrogen oxides (NOx) emissions (APE 002) - Assessment published Dec 2012
-
EEA-32 emissions of nitrogen oxides (NO X ) decreased by 42% between 1990 and 2010. In 2010, the most significant sources of NO X emissions were the 'Road transport' (41%), 'Energy production and distribution' (22%) and the 'Commercial, institutional and households' and 'Energy use in industry' (both 13%) sectors.
The largest reduction of emissions in absolute terms since 1990 has occurred in the road transport sector. These reductions have been achieved despite the general increase in activity within this sector since the early 1990s and have primarily been achieved as a result of fitting three-way catalysts to petrol fuelled vehicles. However, ambient urban concentrations of NO2 in EU-27 countries in recent years have not fallen by as much as reported emissions. From 2001 to 2010, NO2 annual mean concentrations at urban background sites fell by just 10.6% on average (CSI004 - Fig 5) during which time the reported NO X emissions for the EU-27 decreased by 24.9%. The disparity between trends in NO X emissions and ambient NO2 concentration is due in part to increased penetration of diesel vehicles, and the ‘real-world’ emission performance of modern diesel vehicles not showing the improvements that were indicated by the test cycle emission factors used for emission inventories. It is also due to the increased proportion of NO X emitted directly as NO2 from the exhaust of more modern diesel vehicles which use catalyst systems for controlling emissions of other pollutants. As a result of this difference, a number of member states' NO X emissions could be significantly higher than currently calculated.
In the electricity/energy production sector reductions have also occurred as a result of measures such as the introduction of combustion modification technologies (such as use of low NO X burners), implementation of flue-gas abatement techniques (e.g. NO X scrubbers and selective catalytic and non-catalytic reduction techniques, i.e. SCR and SNCR) and fuel-switching from coal to gas.
The National Emission Ceilings Directive (NECD) specifies NO X emission ceilings for Member States that must have been met by 2010. In general, the newer EU Member States have made substantially better progress towards meeting their respective NO X ceilings than the older Member States of the EU-15. Eleven of the twelve post-2004 Member States had reduced their 2010 emissions beyond what is required under the NECD [1] , with the remaining one reporting NO X emissions just 2% above the NECD target. In contrast, only four of the EU-15 Member States reported emissions for 2010 within their respective national ceilings. Of the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), only Switzerland reported 2010 emissions below the level of their 2010 ceiling.
Environmental context: NO X contributes to acid deposition and eutrophication of soil and water. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. Eutrophication can lead to severe reductions in water quality with subsequent impacts including decreased biodiversity, changes in species composition and dominance, and toxicity effects. NO2 is associated with adverse effects on human health, as at high concentrations it can cause inflammation of the airways and reduced lung function, increasing susceptibility to respiratory infection. It also contributes to the formation of secondary particulate aerosols and tropospheric ozone in the atmosphere, both of which are important air pollutants due to their adverse impacts on human health and other climate effects.

Nitrogen oxides (NOx) emissions (APE 002) - Assessment published Dec 2011

EEA-32 emissions of nitrogen oxides (NO X ) have decreased by 41% between 1990 and 2009. In 2009, the most significant sources of NO X emissions were the ‘Road transport’ sector (38%), ‘Energy production and distribution’ sector (22%), ‘Commercial, institutional and households’ sector (15%) and the ‘Energy use in industry’ sector (13%).
The largest reduction of emissions in absolute terms since 1990 has occurred in the road transport sector. These reductions have been achieved despite the general increase in activity within this sector since the early 1990s and have primarily been achieved as a result of fitting three-way catalysts to petrol fuelled vehicles. However, ambient urban concentrations of NO 2 in EU-27 countries in recent years have not fallen by as much as reported emissions. Since 2002, NO 2 average annual mean concentrations at urban background sites have fallen by just 9 %, as indicated in CSI 004, during which time the reported NO X emissions for the EU-27 decreased by 23%. This discrepancy may be a result of a general under-estimation of the effect of catalytic degradation in newer cars, in which case a number of member states’ NO X emissions could be significantly higher than currently calculated.
In the electricity/energy production sector reductions have also occurred, in these instances as a result of measures such as the introduction of combustion modification technologies (such as use of low NO X burners), implementation of flue-gas abatement techniques (e.g NO X scrubbers and selective (SCR) and non-selective (SNCR) catalytic reduction techniques) and fuel-switching from coal to gas.
The National Emission Ceilings Directive (NECD) specifies NO X emission ceilings for Member States that must be met by 2010. In general, the newer EU Member States have made substantially better progress towards meeting their respective NO X ceilings than the older Member States of the EU-15. Ten of the twelve post-2004 Member States had already reduced their 2009 emissions beyond what is required under the NECD, with the remaining two reporting NO X emissions less than 2% above the NECD target . In contrast, only four of the EU-15 Member States reported emissions for 2009 within their respective national ceilings. Thus many Member States required a significant reduction of NO X emissions to have been made in 2010 if they are to meet their obligations under the NECD. Of the three non-EU countries having emission ceilings set under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland) only for Switzerland were emissions in 2009 below the level of their 2010 ceiling.
Environmental context: NO X contributes to acid deposition and eutrophication. The subsequent impacts of acid deposition can be significant, including adverse effects on aquatic ecosystems in rivers and lakes and damage to forests, crops and other vegetation. Eutrophication can lead to severe reductions in water quality with subsequent impacts including decreased biodiversity, changes in species composition and dominance, and toxicity effects. It is NO 2 that is associated with adverse affects on human health, as at high concentrations it can cause inflammation of the airways. NO 2 also contributes to the formation of secondary particulate aerosols and tropospheric ozone in the atmosphere - both are important air pollutants due to their adverse impacts on human health.
