A new report on global air pollution show vast improvements in China, while Indian cities remain the world's most polluted. New Delhi is the world's worst capital.

Although Indian cities saw a dip between 2018-19, report authors @MyAirVisual say that's a result of India's dramatic economic slowdown (~8%+ GDP growth cratered to ~5%), and not a sign that new policies (including NCAP) have begun to have an impact.

@MyAirVisual New Delhi, a city I called home for a few years, remains by far the world's most polluted major city, as politicians and courts spar over responsibility. Delhi is actually worse off in 2019 (Avg PM2.5 levels of 98.6) compared to 2015 ( 97.1).

@MyAirVisual One quirk of these reports is breaking out satellite cities of Delhi. In this report, the nearby city of Ghaziabad is actually ranked the world's most polluted. Noida, Greater Noida, Gurugram, Faridabad and Bhiwadi (in Rajasthan), all of them close by, are all ranked in top 20.
@MyAirVisual One thing that comes out clearly in this report is that air pollution is a major crisis in South Asia. Bangladesh is actually the worst country on a population-weighted avg, while Pakistan, India, Afghanistan and Nepal all rank in worst 10.

@MyAirVisual The new @MyAirVisual report also showed an alarming rise in air pollution across several major Southeast Asian cities, including Jakarta, Seoul and Chiang Mai. Indonesia's capital is now worst in SE Asia and fifth worst capital globally.

@MyAirVisual Also worth noting: As President Trump visits Delhi today, it currently has the worst air of any city on the planet. The AQI level is 249 -- with levels of deadly PM 2.5 at an unbelievable 199. airvisual.com/india/delhi
