The EEA monitors Europe’s air quality through a network of more than 4,000 local air pollution measurement stations across Europe. Most of the stations, managed by the EEA’s member countries in the European Environment Information and Observation Network (Eionet), record hourly data on key air pollutant concentrations and send it to the EEA.
The European Air Quality Index uses the monitoring data to allow users to understand more about air quality where they live, work or travel. Displaying up-to-date information for Europe, users can gain insights into the air quality in individual countries, regions and cities.
Similar air quality information can be found on the Copernicus Atmosphere Monitoring Service (CAMS) that provides daily analyses of hourly concentrations of the regulatory air pollutants.
Although emissions of air pollutants have decreased substantially in Europe over recent decades, poor air quality continues to harm human health and the environment. Poor air quality causes an estimated 400 000 premature deaths in Europe every year and it is the single largest environmental health risk in Europe. A significant proportion of Europe’s population lives in areas where air pollution poses risks to their health.
