News on environmental zones and air pollution

The regional Environment Ministry has recently published the statistics, the problem is not particulate matter (the limit values are observed everywhere), but nitrogen oxides. In Bonn, Dortmund, Düren, Düsseldorf, Hagen and Cologne the nitrogen oxide values are above 50µg/m³! Despite the good trend further diesel driving bans could be demanded in the future and confirmed for Bonn and Cologne.
