The aim of this short communication is to estimate the effects of the implementation of more restrictive lockdown measures on pollution levels in Italy. Using a time series of weekly concentrations of PM10, PM2.5 and NO2 for the period 2016–2020 across 71 provinces, we find that the introduction of lockdown measures reduced the air concentration levels of PM10 and NO2 by 17–18%, while their effect on PM2.5 remains unclear. These results indicate that the lockdown had a significant positive impact in terms of lives saved and improved air quality.

Abstract
The aim of this short communication is to estimate the effects of the implementation of more restrictive lockdown measures on pollution levels in Italy. Using a time series of weekly concentrations of PM10, PM2.5 and NO2 for the period 2016–2020 across 71 provinces, we find that the introduction of lockdown measures reduced the air concentration levels of PM10 and NO2 by 17–18%, while their effect on PM2.5 remains unclear. These results indicate that the lockdown had a significant positive impact in terms of lives saved and improved air quality.File in questo prodotto:
