TORINO. How is the air we breathe in the big cities after this long period of Iockdown? Undoubtedly the long blockade has had considerable effects on the movements of citizens and therefore on emissions from the transport sector.

The level of smog in the period March-April 2020 marked a setback in several Italian cities. But where has the air been cleaned up better thanks to the lockdown? The main collapse of nitrogen dioxide (NO2) occurred in Rome, where the average concentrations are lower than the previous years (2016-2019) by 59% for March and 71% for April respectively. In Turin, on the other hand, the decrease was 43% for March and 51% for April, in Milan there was a reduction of 29% and 43% compared to the average for the same period 2016-2019, while Naples respectively recorded a reduction of 33 % and 57%.

Turin closed for the coronavirus is cleaner and quieter: this is how the city looks without traffic

This is what emerges from “Mobilitaria 2020” the annual study of Kyoto club and Institute on air pollution of the National Research Council (Cnr-Iia) which focuses on the trend of air quality and urban mobility policies in the 14 major cities in 2019-2020 and in the first four months of this year, being illustrated in a webinar on Facebook.
