The low emission zone in Leipzig, Germany, has reduced the highly toxic matter soot and ultrafine particle number concentrations by 47 and 56%, respectively.
This significant reduction was achieved due to the fitting of diesel particle filters to meet the LEZ emission standards. This is similar to the reduction seen in the Berlin LEZ, but using a different assessment method. This strengthens the robustness of both assessments.
