Survey on Low Emission Zones

The Low emissions Zone (LEZ) is the most effective measure that cities can tale to reduce air pollution problems in their area. By the end of February 2015 78 cities in Germany implemented a LEZ where the most polluting vehicles are restricted from entering. Only trough consistent monitoring LEZ can fully develop its positive effect. Therefore the DUH conducts an annual survey in all the environmental zones in Germany on how the competent authorities monitor violations. The survey addresses the respective authorities in the cities and municipalities which are responsible for the implementation of air control measures. Only by systematically monitoring the instrument emission zone fully unleash its positive effect on the reduction of air pollution. Through the annual surveys and the pressure on local authorities for good implementation of LEZ regulations we secured a change in legislation. This clarified different definitions of previous regulations and enables a consistent monitoring.

The DUH conducted regular surveys in cities and German federal states about activities towards sootfree construction sites and construction works. National Guidelines about the use of low emission construction machinery in public announcements are determined, but they’re not well implemented. This Surveys aims to push the topic at a regional and national level.

In other European countries, surveys are conducted to find out which measures are intended to guarantee adherence to the limit values. The aim is to find out Best-practice measures and raise the awareness of air quality control.
