London's low emission zone (LEZ) only caused a modest reduction in nitrogen oxide pollution, according to a study published in The Lancet Public Health. A new report by the University of East Anglia and Imperial College London found that while there was an increase in NOx emissions from vehicles on London’s streets between 2012 and 2015, this did not translate into The researchers concluded that more radical solutions were needed to tackle pollution levels.
