NEW DELHI — The planned city of Gurugram, one of India’s industrial hubs, has glass-sided office buildings and swanky, high-rise apartments. But now, according to a new report, it can claim a less desirable distinction: the city with the world’s worst air.

India holds 15 of the top 20 spots in that category, according to the report, which was released this week by Greenpeace and IQAir AirVisual, a software company that tracks air quality data. The Pakistani city of Lahore and Dhaka, the capital of Bangladesh, also made the top 20, making South Asia — where governments are routinely criticized for failing to limit emissions and coal use — an especially toxic region.

“At a country level, weighted by population, Bangladesh emerges as the most polluted country on average, closely followed by Pakistan and India,” the report said.

Details from the report, which looked at data from more than 3,000 cities around the world, offer more bad news for India’s nascent movement to curb air pollution. Average levels of the tiny, dangerous particles known as PM 2.5, which can penetrate deep into the lungs and enter the bloodstream, were largely unchanged from 2017 to 2018 in many Indian cities featured in the report.
