Diesel-vehicle ban approved for German cities

Due to a landmark court ruling, some German cities will be allowed to ban older diesel vehicles. According to the Federal Administrative Court in Leipzig, the two of Germany’s most polluted cities can now legally ban older diesel vehicles. The environmental group DUH brought the cases after about 70 German cities exceeded European Union limits for nitrogen oxides (NOx), last year. The danger of diesel emissions containing nitrogen oxides is that it can cause respiratory disease.
