The Digital Berlin Air Quality Map captures air pollution across the city in 50 × 50 metre grid cells. The map is based on 2024 annual average concentrations of NO₂, PM₁₀ and PM₂,₅ and classifies pollution levels into five categories, ranging from ‘very low’ to ‘high’. This classification follows the World Health Organization (WHO) guidelines and interim targets designed to achieve air quality standards that do not pose a risk to human health according to the current state of scientific knowledge.
Results and spatial distribution:
- 48% of the urban area exhibits low levels of air pollution. Yet, only 15% of the population lives there (e.g. Müggelsee, Grunewald).
- 74% of Berlin’s residents live in regions with moderate air quality, mostly housing estates near roads. These areas make up just 46% of the city’s total area.
- 6% of the area experiences elevated pollution levels, affecting 11% of the population (e.g. along major roads).
- There are currently no regions with ‘very low’ pollution levels or full WHO compliance.
Health impacts: particulate matter, especially PM2.5, is harmful to human health, even at very low levels. It can lead to cancer, neurological disorders, and respiratory illnesses, among other effects, and poses risks to unborn children. These pollutants can travel through the respiratory system and reach internal organs, including the brain.
Measures to improve air quality:
- Transport ‒ low-emission zones, speed limits, expansion of public transport
- Heating ‒ low-emission systems, filters, proper use of wood-burning stoves
- Industrial and transboundary sources ‒ Europe-wide measures to reduce emissions
The map supports both residents and local authorities in identifying where targeted air quality improvements are needed.
