Lovely to hear that "Random sample measurements on the road have shown that the emissions reduction of good Euro-6d-TEMP diesels compared with average Euro 5 diesels is as high as 95 to 99 percent".

This is presented in the following article  Some people have the impression that air pollution by NOx (nitrogen oxides) in Germany is as high as never before. In fact, the opposite is the case.

What do you think?
