In 2020, 84% of all monitored countries observed air quality improvements

Delhi remained the most polluted capital city in the world but India, on the whole, had improved its average annual PM 2.5 (particulate matter) levels higher in 2020 than in 2019, according to a report from IQ Air, a Swiss air quality technology company, specialising in protection against airborne pollutants, and developing air quality monitoring and air cleaning products.

Delhi’s concentration level, based primarily on data from the Central Pollution Control Board, was 84.1 µg/m³ in 2020, a 15% improvement from the 98.6 µg/m³ recorded in 2019 — a consequence of the lockdown. Average pollution levels were 51.9 µg/m³ in 2020 compared with 58.1 µg/m³ in 2019, making India only the third most polluted country in 2020, unlike in 2019, when its air was the fifth most noxious.
