Emissions from car exhausts exceeded EU thresholds for nitrogen oxide at half of Germany’s monitoring stations. While 2014 is among the lowest years for particulates levels, the Federal Environment Agency sees no reason for relief. Nitrogen oxide, primarily originating from motor vehicle exhausts, is quickly becoming a top pollutant in Germany, according to a preliminary analysis conducted by the Federal Environment Agency (UBA). Data collected at over 500 monitoring stations indicates that, once again, the annual mean value of more than half of the monitoring stations near high-traffic roads exceeded the threshold of 40 µg per cubic metre (m3).
