Impacts of Low Emission Zones in Germany on Air Pollution Levels

Since 2008 low emission zones (LEZ) have been introduced in many German cities to improve air quality and to protect human health.
 

In order to assess the effectiveness of LEZ, both descriptive and statistical analyses have been conducted based on concentrations of air pollutants (PM10, PM2.5, NO, NO2, and NOx) from relevant monitoring stations in Germany from year 2002 to 2012. The results of this study indicate that the introduction of LEZ has brought positive effects on reducing air pollutant concentrations.
