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.
[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.

Distance-to-target for EEA member countries
-
The distance-to-target indicator shows how current emissions compare to a linear emission reduction 'target-path' between 2010 emission levels and the 2020 Gothenburg emission ceiling for each country. Negative percentage values indicate the current emissions in a country are below the linear target path; positive values show that current emission lie above a linear target path to 2020.

Emissions of acidifying substances (CSI 001) - Assessment published Dec 2012
-
Emissions of the acidifying pollutants, nitrogen oxides (NO X ), sulphur oxides (SO X ) and ammonia (NH 3 ), have decreased significantly in most of the individual EEA member countries between 1990 and 2010. Emissions of SO X have decreased by 75%, NO X by 42% and NH 3 emissions by 28% since 1990 within the EEA-32.
Data reported under the NECD indicates that the EU-27 as a whole has met its overall target to reduce emissions of SO X and NH 3 as specified by the EU’s National Emissions Ceiling Directive (NECD). However twelve individual Member States, and the EU as a whole, reported emissions in the 2010 above their NECD 2010 emission ceilings for NO X , although the twelve Member States joining the EU in 2004/7 reported combined emissions below their collective NECD ceiling. Three EU-27 member states also reported 2010 NH 3 emissions above the levels of their NECD ceilings, neither of which are in the group of twelve new EU member states.
Of the three non-EU countries having emission ceilings for 2010 under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), both Liechtenstein and Norway reported NO X emissions in 2010 that were substantially higher than their respective 2010 ceilings. Liechtenstein also reported 2010 NH 3 emissions above the level of their Gothenburg protocol 2010 ceiling.

Emissions of acidifying substances (CSI 001) - Assessment published Dec 2011
-
Emissions of the acidifying pollutants (nitrogen oxides (NO X ), sulphur oxides (SO X ) and ammonia (NH 3 ) have decreased significantly in most of the individual EEA member countries between 1990 and 2009. Emissions of SO X have decreased by 76%, NO X by 41% and NH 3 emissions by 26% since 1990.
The EU-27 is on track to meet its overall target to reduce emissions of SO X and NH 3 as specified by the EU’s National Emissions Ceiling Directive (NECD). However a number of individual Member States, and the EU as a whole, anticipates missing their NECD 2010 emission ceilings for NO X .
Of the three non-EU countries having emission ceilings for 2010 under the UNECE/CLRTAP Gothenburg protocol (Liechtenstein, Norway and Switzerland), both Liechtenstein and Norway reported NO X emissions in 2009 that were substantially higher than their respective 2010 ceilings.

Sulphur dioxide SO2 emissions (APE 001) - Assessment published Dec 2011
-
EEA-32 emissions of sulphur dioxide (SO 2 ) have decreased by 76% between 1990 and 2009. In 2009, the most significant sectoral source of SO X emissions was Energy production and distribution (70%), followed by emissions occurring from Energy use in industry (13%) and in the Commercial, institutional and households (9%) 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-containing 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 already reduced their national SO X emissions below the level of the 2010 emission ceilings set in the National Emission Ceilings Directive (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 also below the level of the 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 potential 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.
