The novel coronavirus (COVID-19) crisis has affected numerous industries around the world, but it has also had an impact on air pollution. The first day of the United Kingdom lockdown saw noticeable drops in nitrogen dioxide (NO2) emissions in cities across the country.
The most dramatic decline was observed in Edinburgh. On March 26, 2020 the average daily NO2 emissions amounted to 28µg/m3, compared with 74µg/m3 recorded on the same day the previous year. This was followed by London Westminster, where emissions fell from 58µg/m3 to 30µg/m3. Not all cities saw as noticeable a decline, with daily emissions on this day in Manchester Piccadilly dropping by just 7µg/m3 from the previous year.
