Air pollution still too high across Europe

Road transport is one of Europe’s main sources of air pollution, especially of harmful pollutants such as nitrogen dioxide and particulate matter, according to the EEA ‘Air quality in Europe — 2018 report’.  Emissions from agriculture, energy production, industry and households are also contributing to air pollution. The report presents the latest official air quality data reported by more than 2 500 monitoring stations across Europe in 2016.

Health impacts of air pollution significant

Particulate matter (PM), nitrogen dioxide (NO₂) and ground level ozone (O₃) cause the biggest harm to human health. High concentrations of air pollution continue to have a negative impact on Europeans, especially those living in urban areas. Air pollution also has considerable economic impacts, cutting lives short, increasing medical costs and reducing productivity across the economy through working days lost due to ill health. Air pollution also negatively impacts ecosystems, damaging soils, forests, lakes and rivers and reducing agricultural yields.

Past and current policies and technology advances have led to slow but steady progress in reducing these negative impacts. Updated estimates in the report indicate that concentrations of PM_2.5 were responsible for about 422 000 premature deaths in 41 European countries in 2015, of which around 391 000 were in the 28 EU Member States. A wider assessment included in this year’s report, looking back to 1990, shows that premature deaths due to PM_2.5 have been cut by about half a million premature deaths per year. This is due to the implementation of European air quality policies and the introduction of measures at national and local level which have led, for example, to cleaner cars, industry and energy production.

‘Air pollution is an invisible killer and we need to step up our efforts to address the causes. In terms of air pollution, road transport emissions are often more harmful than those from other sources, as these happen at ground level and tend to occur in cities, close to people. That is why it is so important that Europe redoubles its efforts to reduce emissions caused by transport, energy and agriculture and invest in making them cleaner and more sustainable,’ said EEA Executive Director Hans Bruyninckx. ‘Tackling these sectors in an integrated way can deliver clear benefits for both air quality and climate, and will help to improve our health and wellbeing.’

EU Commissioner for Environment, Maritime Affairs and Fisheries Karmenu Vella added: 'I very much welcome this report by the European Environment Agency. It shows us that air policy does work, but it also reminds us that we need to make it work even better to achieve clean air across Europe, for all citizens. The European Commission has acted resolutely on air pollution, and will continue to work with Member States to make sure that air quality rules are fully applied on the ground.'

Other Key Findings

Particulate Matter: For PM_2.5 (particles with a diameter of 2.5 micrometres or less), the percentage of the EU-28 urban population exposed to PM_2.5 stood at 6% in 2016, down from 7% the year before. But approximately 74% of the EU urban population were exposed to concentrations exceeding the stricter WHO guidelines. Exposure to PM_2.5 caused the premature death of an estimated 422 000 people in 41 countries in 2015.

Nitrogen dioxide: The annual limit value for NO₂ continues to be widely exceeded across Europe. In 2016, 7% of the EU-28 urban population lived in areas with concentrations above the annual EU limit value and the WHO guidelines. This is down from 9% in 2015. Exposure to NO₂ caused the premature death of an estimated 79 000 people across 41 European countries in 2015.

Ground-level ozone: About 12% of the EU-28 urban population were exposed to O₃ levels above the EU’s target value in 2016, which is a considerable decrease from 2015 (30%). However, the percentage is still higher than the 7% recorded in 2014. Around 98% were exposed to levels exceeding the stricter WHO guidelines. Exposure to ozone caused the premature death of an estimated 17 700 people in 41 European countries in 2015.

New EEA briefing explaining health risk assessments

A briefing also published today, the ‘EEA’s health risk assessments of air pollution,’ provides a detailed overview of how the EEA calculates its annual air quality health estimates that quantify the impacts of air pollution on population health.

The health impacts of exposure to air pollution are diverse, ranging from inflammation of the lungs to premature deaths. In the case of the health risk assessment undertaken by the EEA, mortality is selected as the health outcome that is quantified, as it is the one for which the evidence is most robust. Mortality due to the exposure to air pollution is estimated in terms of “premature deaths” and as “years of life lost”. The estimated health impacts in the EEA air quality report are those attributable to exposure to PM_2.5, NO₂ and O₃ in Europe in 2015. These estimates are based on information on air pollution, demographic data and the relationship between exposure to pollutant concentrations and specified health outcomes. The estimates provide a measure of the general impact of air pollution across a given population and for example, cannot be assigned to specific individuals living in a specific geographical location.

Note on premature death estimates

The impacts estimated for the different pollutants cannot be simply added to determine the estimated total health impact attributable to exposure. For example, as concentrations of PM_2.5 and NO₂ are (sometimes strongly) correlated, the impacts estimated for these cannot be aggregated. Doing so may lead to a double counting.
