Today we review research on measuring NO2 emissions from EU standard and diesel vehicles using remote sensors on roadways in London. Results show that while NO2 concentrations have slowly decreased over the last decade due to more stringent EU standards, there has not been a similar improvement in diesel vehicles. For the latter, care must be taken in reducing NO2 that increases in Particulate Matter (PM) are avoided.
