The general air quality of the past years is also described by an index.
It provides a general overview of the air quality situation in a given city all the year through and compare to European norms.

The regulations taken into account are some of the annual standards and objectives defined by the European directives. However, this index is aimed at better taking into account long term public exposure to air pollution but can not be used for compliance checking.

Click on a city to see the situation of every individual pollutant taken into account and their historical evolution.
