This report is London’s response to the UK Government Air Quality Expert Group's (AQEG) call for evidence on changes in air pollution during the COVID-19 outbreak.
The report shows that levels of harmful gas nitrogen dioxide (NO2) at some of London’s busiest roads reduced by around a half since measures to tackle COVID-19 were introduced. This is in addition to the significant reductions already delivered by policies including the world’s first Ultra Low Emission Zone (ULEZ).
For other pollutants the picture is more complex. In the period since COVID-19 measures were introduced there have been a number of moderate particulate matter episodes, resulting in a significant increase in particulate matter.
