Greenpeace report names India as the most polluted country in the world

India has been named as the world’s most polluted country in an analysis of air quality across the globe.

The findings, from Greenpeace and AirVisual, found that 22 of the 30 most polluted cities in the world were in India, with Gurugram topping the list.

In 11th place, Delhi is also the world’s most polluted capital city.

Other cities that featured in the top 30 included Aksu in China, Dhaka in Bangladesh and Lahore, Pakistan.

United States Air Quality Index (US AQI)
United States Air Quality Index (US AQI) – The US AQI is one of the most widely recognized AQI systems available. The US AQI converts pollutant concentrations
into a color-coded scale of 0-500, to easily represent the level of associated health risk. The US AQI’s “Good”
range (<12μg/m3) is slightly higher than the WHO Air Quality Guideline (<10μg/m3).

The air quality readings measure particulate matter and other pollutants for every month, comparing pollution levels to World Health Organisation limits for air pollutants.

Most cities topping the list presented unhealthy, very unhealthy or hazardous pollution levels for several months during 2018.

A report released by the University of Chicago last year found that global life expectancy is cut by two years as a result of particulate matter air pollution.

The report also found that 288 million people in India would live seven years longer on average if World Health Organisation limits for pollution were followed.
