News on environmental zones and air pollution

Stuttgart - capital of nitrogen oxides

At the end of 2018, opponents of diesel traffic restrictions claimed that air quality had improved and that, above all, fine particle values had decreased. However, after the analysis of the values measured last year it becomes clear: nowhere in Germany were the values of nitrogen oxides higher in 2018 than in Stuttgart. As a result, traffic restrictions should no longer be questioned as they aime at reducing nitrogen oxide.
