According to the European Space Agency (ESA), as well as a handful of independent researchers, nitrogen dioxide emissions have significantly decreased over Italy following the lockdown caused by the spread of COVID-19.
The Copernicus Sentinel-5P satellite detected a decline in NO2 emissions signaling the decrease in air pollution, with the most significant change being observed in the northern part of the country.

The new coronavirus first appeared in Wuhan in December. By January, officials had quarantined the city — halting planes, trains, subways, and most private vehicles.
The cleaner air will hopefully provide some relief as China copes with a novel coronavirus that affects the lungs. On its own, nitrogen dioxide can inflame airways and make it harder for people to breathe. It also reacts with other chemicals to create soot, smog, and acid rain.
