Characteristics of mobility


Exhaust gases

Although the air quality in Berlin has improved noticeably in recent years, it is still impaired by motorized road traffic, which directly emits air pollutants hazardous to health, such as particulate matter (PM10) and nitrogen dioxide (NO2), as well as the greenhouse gas carbon dioxide (CO2). Since 2004, average annual particulate matter pollution in Berlin has been below the EU limit. However, the more stringent 24-hour pollution limit is still occasionally exceeded. An important step towards a reduction in hazardous pollution was the introduction of the environmental traffic zone in 2008. After implementation of the first phase of the environmental traffic zone, emissions of diesel soot were already reduced by about 35 percent and emissions of nitrogen dioxide by around 19 percent.

Although a modest downward trend can be detected in the last ten years, traffic continues to produce around a quarter of climate-relevant CO2 emissions in Berlin.
