Study shows the world’s dirtiest air is in India

SINGAPORE • Seven of the top 10 most polluted cities in the world are in India, according to a new study showing South Asia’s battle with deteriorating air quality and the economic toll it’s expected to take worldwide.

Gurugram, located southwest of India’s capital New Delhi, led all cities in pollution levels in 2018, even as its score improved from the previous year, according to data released by IQAir AirVisual and Greenpeace. Three other Indian cities joined Faisalabad, Pakistan, in the top five.

“This has enormous impacts, on our health and on our wallets,” Yeb Sano, ED of Greenpeace South-East Asia, said in a statement released with the figures. “In addition to human lives lost, there’s an estimated cost of US$225 billion (RM916.97 billion) in lost labour and trillions in medical costs.”

India makes up 22 of the top 30 most polluted cities, with five in China, two in Pakistan and one in Bangladesh. India racks up health-care costs and productivity losses from pollution of as much as 8.5% of GDP, according to the World Bank.

China made marked progress in its usually dismal pollution levels, with average concentrations falling by 12% in 2018 from the previous year, according to the data.

Sano traced much of the problematic readings back to climate change. He noted that burning fossil fuels is both the key driver of climate change and of air pollution worldwide, and that shifting atmospheric conditions have worsened air quality and amplified forest fires. — Bloomberg
