Indicator: Air quality in agglomerations

A graph for three air pollutants shows the extent to which the WHO recommendations from 2021 will be exceeded on average in urban areas between 2000 and 2023. The development of the various pollutants varies. Between 2000 and 2023, values for NO2 are between 172 and 31 percent, for ozone between 44 and 32 percent and for PM2.5 between 255 and 60 percent.

The basic pollution levels in German conurbations significantly exceed WHO recommendations from 2021 for particulate matter (PM2.5) and nitrogen dioxide (NO₂).In the vicinity of pollutant sources, pollution levels can even be significantly higher.The situation for NO₂ and PM2.5 has improved considerably since 2000, but the WHO recommendations for 2021 are still clearly exceeded.Ozone and PM2.5 pol... read more
