Read our privacy policy Air pollution over northern Italy has fallen sharply after the coronavirus forced the country into a nationwide lockdown, satellite imagery has revealed. The European Space Agency timelapse video taken from above the Earth, which runs from the start of the year until this week, shows a marked drop in emissions of nitrogen dioxide, a noxious gas emitted by power plants, cars and factories, over northern Italy. “Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see coincides with the lockdown in Italy causing less traffic and industrial activities,” said Claus Zehner, who manages the Copernicus Sentinel-5P, the satellite which took the photos over the Po Valley region. Two weeks later, Italian prime minister Giuseppe Conte announced the expansion of the quarantine zone to cover much of northern Italy, affecting at least 16 million people, restricting travel from, to or within the affected areas, and banning cultural events.
