Stronger measures needed to tackle harm from air pollution

The EEA report ‘Air quality in Europe — 2016 report’ presents an updated overview and analysis of air quality in Europe from 2000 to 2014 based on data from official monitoring stations across Europe, and including more than 400 cities. It shows that in 2014 around 85 % of the urban population in the EU were exposed to fine particulate matter (PM_2.5) at levels deemed harmful to health by the World Health Organization (WHO). Particulate matter can cause or aggravate cardiovascular diseases, asthma and lung cancer.

The report also provides new estimates⁽¹⁾ of the health impacts of the most harmful air pollutants based on 2013 data. Exposure to PM_2.5 was responsible for about 467 000 premature deaths in 41 European countries in 2013. Within the European Union, premature deaths exceeded 430 000. The estimated impacts of nitrogen dioxide (NO₂) and ground-level ozone (O₃) exposure were around 71 000 and 17 000 premature deaths respectively in Europe.

“Emission reductions have led to improvements in air quality in Europe, but not enough to avoid unacceptable damage to human health and the environment,” said EEA Executive Director Hans Bruyninckx. “We need to tackle the root causes of air pollution, which calls for a fundamental and innovative transformation of our mobility, energy and food systems. This process of change requires action from us all, including public authorities, businesses, citizens and research community.”

Karmenu Vella, European Commissioner for the Environment, Maritime Affairs and Fisheries, welcomed the report and added: “Today's  EEA report on air quality reminds us that we need to keep this subject high on the political agenda. The European Commission is doing so, and is committed to securing improvements in air quality. One way we can do that is to help different levels of government work better together. If a lot of air quality blackspots are in towns and cities then it is clear that local and regional governments play a central role in finding solutions. This week I hope that the European Parliament will vote positively on our reduction commitments in the new National Emission Ceilings Directive. This will provide direction for national and local actors." 

The report highlights that air quality has however improved over the years. The annual average PM₁₀ has fallen in 75 % of monitored locations during the period 2000–2014. Similarly, PM_2.5 concentrations, on average, have decreased between 2006 and 2014 for all station types (urban, traffic, background sites, etc.). Exposure to PM levels above WHO recommendations have also decreased over the years. 

Other key findings

• In 2014, 16 % of the EU-28 urban population was exposed to PM₁₀ levels above the EU daily limit value whereas 8 % was exposed to PM_2.5 levels above the EU target value. However, when compared to the stricter WHO Air Quality Guideline values set to protect human health, approximately 50 % and 85 % of city dwellers were exposed to PM₁₀ and PM_2.5 concentrations exceeding the WHO’s recommendations.
• NO₂ affects the respiratory system directly, but also contributes to the formation of PM and O₃. In 2014, 7 % of the urban population in the EU-28 were exposed to NO₂ concentrations above the identical WHO and EU standards, with 94 % of all exceedances occurring due to traffic.
• PM_2.5 emissions from coal and biomass combustion in households and from commercial and institutional buildings have not decreased to any significant degree. To lower emissions from these sectors, it is essential to fully implement measures, such as recent changes to the Eco-design Directive for household stoves, the Medium Combustion Plant Directive, and to provide public guidance on good household burning practices, etc.
• Emissions of ammonia (NH₃) from agriculture remain high and contribute especially to sustained PM levels and a number of high-PM episodes in Europe.
• Air pollution continues to damage vegetation and ecosystems. In this context, the most harmful air pollutants are O₃, NH₃ and NO_x. 

Revision of the National Emission Ceilings Directive

Following the political agreement reached with the Council in June of this year, the European Parliament formally votes this week on the revised National Emission Ceilings (NEC) Directive. Member States are subsequently also expected to confirm their agreement of the revised directive before the end of 2016. The legislative proposal will establish new national emission reduction commitments applicable from 2020 and 2030 for SO₂, NO_x, NMVOC, NH₃, and PM_2.5 which will help Member States in their efforts to improve air quality.
