Delhi most polluted capital, India has 18 of top 30 worst AQI ranked cities

While Ghaziabad topped the list of most polluted regional cities (110 PM2.5), India ranked sixth on the list of 98 countries in PM2.5 concentration just behind Pakistan.

With an average of 98.6 Particulate Matter (PM 2.5) concentration, Delhi topped the list of most polluted capital cities in the world. 18 of the 30 most polluted cities in 2019 were from India. A recent report released by AirVisual, which monitors international air pollution, revealed the startling fact despite the government’s push to reduce air pollution.

While Ghaziabad topped the list of most polluted regional cities (110 PM2.5), India ranked sixth on the list of 98 countries in PM2.5 concentration behind Pakistan and Bangladesh. The majority of polluted cities and countries in the report are in the South Asia region, which includes 30 of the top 40 most polluted cities and four of the five most polluted countries.

“While pollution sources across the region vary, common contributors include transportation emissions, biomass burning for household cooking, open agricultural burning, industry, and coal combustion,” the report said.

Delhi experienced its longest period of hazardous air pollution during late October and early November 2019. The grim situation had forced the government to declare a public health emergency, temporarily ordering schools to close and construction activities to be stopped during the night.

Commenting on the World Air Quality Report 2019, Avinash Chanchal, Senior Campaigner at Greenpeace India said, “In Delhi, be it bypass roads, shutting down of Badarpur power plant, shifting the industries to PNG and BS-VI mandate have resulted in reduction of pollution levels on an annual average basis, supported by favorable meteorological conditions in 2019, but latest World Air Quality Report is an indication that the steps taken are not sufficient.”

The report highlighted the government’s actions in curbing air pollution with the launch of the National Clean Air Programme (NCAP) to reduce PM2.5 and PM10 in 102 cities by 20-30 per cent by 2024 compared to 2017 levels. “While the long-term impacts of these activities are yet to be seen, India saw widespread improvements in PM2.5 levels in 2019, compared to 2018 as a result of economic slowdown, favorable meteorological conditions, as well as more dedicated efforts towards cleaning the air,” the report added.

Despite the efforts, India still leads the ranking of polluted cities with half of the 50 most polluted cities. Meanwhile, none of the Indian cities monitored for the report met the World Health Organisation (WHO) target for annual pollution exposure during 2019.
