The European Space Agency (ESA) has just released air pollution monitoring data during the outbreak blockade and has found a drop in carbon dioxide emissions in Italy. Similar to the January-February study of places such as Wuhan in China, transportation and industrial activity declined in many places as the COVID-19 outbreak spread sprinth son worldwide, experts said. Italy, which has adopted the city-blocking measures, has also fallen on its air pollution index.
The European Space Agency (ESA) is known to be aware of the distribution of trace gases in the atmosphere, including methane, carbon monoxide, sulfur dioxide, nitrogen dioxide, etc., based on data collected by the Sentinel-5P satellite.
Typically, vehicles such as cars, trucks, buses, and the burning of fossil fuels from power plants and other industrial facilities contribute the most to nitrogen dioxide emissions.
A few weeks ago, nasa’s research report in China noted that nitrogen dioxide emissions in the country had fallen sharply as regional measures were imposed.

A similar process can be seen in Italy by comparing nitrogen dioxide emissions data across Europe between January 1 and March 11.
The decline in nitrogen dioxide emissions in the Bo Valley region of northern Italy is particularly marked, said Klaus Zehner, mission director at ESA Copernicus Sentinel-5P.
Although cloud and weather changes can lead to slightly different data, ESA has considerable confidence that the reduction in pollutant emissions is in parallel with Italy’s closure measures.
