Ghaziabad provided an Average Air Quality Index (AQI) of 2.5 Particulate Matter at 106.6ug/m3.

The author states, “As one of the fastest developing countries around the world, with its industrial sector growing at a rate of 13% per year, vehicles and industrial emissions are the major contributors to air pollution in this country of 165 million people."

"India continues to feature prominently at the top of the most polluted cities ranking, with 22 of the top 30 most polluted cities globally," the report said.

The global cities ranking report is based on PM2.5 data from 106 countries, which is measured by ground-based monitoring stations, most of which is operated by government agencies.

The report also reveals the impact of COVID-19 lockdown and behavioural changes on global particulate pollution (PM2.5) levels.

Major sources of India's air pollution include transportation, biomass burning for cooking, electricity generation, industry, construction, waste burning and episodic agricultural burning.

Of the 50 most polluted cities worldwide, 49 are in Bangladesh, China, Pakistan, and India. The report on the world's best and worst places for clean air in 2020 was prepared based on the average value of PM2.5 concentration in µg/m³ by collecting data from Swiss air quality expert IQAir.
