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

Key messages

Aggregated emissions of acidifying gases (NH3, NOx, SO2) have decreased significantly in most EEA member countries between 1990 and 2005 (Figure 1) despite increased economic activity (GDP) occurring during this period. However, meeting the 2010 NOx emission ceilings is likely to be a problem for a number of countries.

Emissions in the EU-15 Member States decreased by 47% since 1990 from 1 025 kt to 539 kt (Figure 2). The EU-15 is well on track on meeting its overall 2010 NECD target for acidifying pollutants.

Between 1900 and 2005 emissions of acidifying pollutants in the new EU-12 countries declined significantly from 503 kt to 206 kt, a reduction of 59% (Figure 3).  The new EU-12 is also on track on meeting its overall 2010 NECD target for acidifying substances.

Key assessment

Emissions of acidifying gases have decreased significantly in most EEA member countries, with the highest reductions in Czech Republic and Latvia (Figure 4). However, emissions of acidifying pollutants have increased in Greece, Cyprus and Turkey between 1990 and 2005.  A recent study performed for the European Commission (http://ec.europa.eu/environment/air/pollutants/nationalprogr_dir200181.htm) indicates that 10 out of 23 EU-27 countries (excluding Greece, Romania, Bulgaria and Luxemburg) predict that their 2010 emission estimates will be higher than their NECD target value for NOx under implemented and planned policies and measures. Only 1 out of 23 Member States predicted that they will not meet their SO2 NECD target in 2010.

In the EU-15, emissions decreased by 47% between 1990 and 2005, mainly as a result of reductions in sulphur dioxide emissions, which contributed 76% of the total reduction of acidifying pollutants. Emissions from the energy, industry and transport sectors have all been significantly reduced, and contributed 61%, 17% and 17%, respectively, of the total reduction in weighted acidifying gas emissions. This reduction is mainly due to fuel switching to natural gas, economic restructuring of the new Lander in Germany and the introduction of flue gas desulphurisation in a number of power plants. So far, the reductions have resulted in the EU-15 being on track to reaching the overall target for reducing acidifying emissions in 2010. However, 9 out of 13 EU-15 Member States (excluding Greece and Luxemburg) indicated that there are unlikely to meet their NECD ceiling for NOx or SO2 (http://ec.europa.eu/environment/air/pollutants/nationalprogr_dir200181.htm).

Emissions of acidifying gases have also decreased significantly in the new EU-12 where emissions decreased by 59% between 1990 and 2005, mainly as a result of the large reduction in sulphur dioxide emissions, as in the EU-15 countries. Nine out of 10 new EU-12 countries (excluding Bulgaria, Romania) are well on track of meeting their NECD target for SO2 or NOx (http://ec.europa.eu/environment/air/pollutants/nationalprogr_dir200181.htm). 
The reduction in emissions of nitrogen oxides is due to abatement measures in road transport and large combustion plants.

Specific assessment

Since 1990, the largest absolute decrease in emissions within the EU-15 has occurred in the 'energy industries' sector, which contributed 51% of the total reduction in emissions of acidifying substances (Figure 8). The most significant EU-15 emission sources in 2005 were 'agriculture' (34% of total emissions), 'energy industries' (24% of total emissions), 'road transport' (16% of total emissions) and 'energy use in industry' (10%). In 2005, the EU-15 relative weighted contribution to acidification from SO2 emissions was 28%, NOx emissions 37% and NH3 emissions 35%. Emissions of nitrogen oxide have fallen since 1990 due to abatement measures in road transport and large combustion plants, but these have to some extent been offset by increased road traffic. Ammonia emissions in the EU-15 are stabilising although agriculture emissions (the major source) are difficult to control and to quantify and hence are subject to high uncertainty.

The new EU-12 has experienced a similar percentage reduction of emissions since 1990 from the energy industries as in the EU-15, with 47% of the total reduction in the new EU-12 emissions of acidifying substances occurring from the energy industries sector  (Figure 9). Over the same period, emissions from the combustion-related emissions from industry and agriculture sectors have also decreased significantly. In 2005, the most significant new EU-12 sources were 'energy industries' (42% of total emissions), 'agriculture' (22% of total emissions), 'industry energy' (11% of total emissions), and 'road transport' and 'other transport' (13% of total emissions). In 2005, the new EU-12 relative weighted contribution of SO2 emissions was 53%, NOx was 23% and NH3 emissions contribution was 24%.
