Let me share today another stunning milestone in India’s global leadership. It’s just a number but of course, we know that numbers always tell the story. The number is 517 and it measures something called AQI. The world’s cities and countries compete fiercely when it comes to AQI.
As you might expect, China led the list once, hitting an AQI of 1,600 on January 15, 2018, in the city of Hotan, near the Gobi Desert. China’s capital, Beijing, achieved an AQI of 999 on March 12, 2014.
