The indicator shows the relative air pollution in Treptow-Köpenick, i.e. the number of low, medium and high polluted planning areas (PLR) in Treptow-Köpenick compared to the planning areas of other districts in Berlin.

In order to obtain an overall view of environmental pollution in connection with social justice in Berlin, the state of Berlin has implemented an environmental justice monitoring system. The environmental justice monitoring evaluates existing data of different core indicators (e.g. noise pollution and air pollution) and aggregates these data on a neighborhood level, respectively on a total of 447 so called planning areas (PLR), whereas Treptow-Köpenick is divided into 34 planning areas.

The data basis for the air pollution of the planning areas (PLR) are the area-weighted annual mean values 2009 of the concentration of particulate matter (PM2.5) and nitrogen dioxide (NO2). Subsequently, the determined values were divided into three categories (low: 79 PLRs, medium: 259 PLRs, high: 109 PLRs).

The districts are affected to varying degrees by relative air pollution. In Treptow-Köpenick, 1 PLR is highly polluted, 21 PLRs are medium polluted and 12 PLRs are low polluted.

Overall, air pollution in Berlin increases from the periphery to the center. For PM2.5, the values in the least polluted PLR were 14.8 μg/m³ and in the most polluted PLR 18.4 μg/m³, which means that the benchmark value of 10 μg/m³ recommended by the World Health Organization (WHO) was exceeded in all PLRs in Berlin. For NO2, the values ranged from 11.3 to 27.3 μg/m³, which means that the WHO guideline value of 40 μg/m³ was not exceeded.
