The EEA’s data for recent weeks show how concentrations of nitrogen dioxide (NO2), a pollutant mainly emitted by road transport, have decreased in many Italian cities. For example:
In Milan, average concentrations of NO2 for the past four weeks have been at least 24 % lower than four weeks earlier this year. The average concentration during the week of 16-22 March was 21 % lower than for the same week in 2019.
In Bergamo, there has been a constant decline in NO2 pollution over the past four weeks. The average concentration during the week of 16-22 March was 47 % lower than for the same week in 2019.
In Rome, average NO2 concentrations for the past four weeks were 26-35 % lower than for the same weeks in 2019.
