Nitrogen dioxide levels down in 2017, many cities still exceed limits - UBA
Seventy German municipalities exceeded nitrogen oxide air pollution limits in 2017, down from 90 the previous year, writes the Federal Environment Agency (UBA). This development points in 鈥渢he right direction,鈥� said UBA President Maria Krautzberger, 鈥渂ut we鈥檙e nowhere near our goal.鈥� The main reason for high NO2 levels was diesel car emissions, writes the UBA. The agency says that the decreasing levels indicated that measures initiated because of the diesel emissions fraud scandal were taking effect, such as speed limits and software upgrades for diesel cars. However, Krautzberger argued that hardware engine retrofitting of diesel vehicles was 鈥渢he only way to alleviate health problems caused by nitrogen oxides in a fast and lasting manner.鈥�
