Which city ought to serve as the capital of India? This is the decision made by AQI.

Shashi Tharoor, a Congress lawmaker, bemoaned Delhi's polluting air and advocated for the capital to be relocated. As people began proposing cities for India's capital, this led to a dispute that ran from north to south. This city would be the winner of the opportunity to serve as the capital of India if AQI were the deciding factor.

Delhi is engulfed in deadly pollution, as it has been every November for the past ten years. An irritated Member of Parliament has proposed moving the capital outside of Delhi, despite the fact that Delhiites are struggling to breathe. But if we were to consider shifting the capital from Delhi, which would be the best state capital to move into with clean air as the only parameter?

A capital is selected based on a number of criteria, including connectivity, infrastructure, strategic location, and the state of law and order in relation to the rest of the nation. However, what place would we choose if we were to leave smog-ridden Delhi and only consider pure air?

The inquiry coincides with hundreds of people complaining about Delhi's poisonous haze and Congress MP Shashi Tharoor's frustration, asking whether the capital should be relocated.

While claiming that Delhi was "uninhabitable" for three months from November to January and "barely liveable" for the remainder of the year, Tharoor cited his unsuccessful attempts to purify the city's air.

"Should it even remain the nation's capital?" he inquired.

Delhi is not the only tier-II and tier-III city in the Indo-Gangetic plain that has been affected by the pollution challenge. The toxic smog that kills thousands of people year is caused by both anthropogenic and geographic factors.

People made a number of recommendations regarding which state capital ought to be selected as the nation's capital.

Chennai, India's safest and cleanest city, ought to become the new capital. Federalism will also benefit greatly from the capital being moved to Chennai, according to DMK spokesman Salem Dharanidharan.

He was questioned about the city's frequent floods as a result.

Among the other recommendations was Mumbai, India's financial hub.

Nevertheless, neither Chennai nor Mumbai were listed as having the top air quality index in India.

On November 21, Delhi recorded an AQI of 343; Chennai and Mumbai had'moderate' air quality, with AQIs of 135 and 119, respectively.

The air quality was poor in Chandigarh (259) and Kolkata (212).

The northeast is home to all of the top state capitals in terms of AQI.

The two worst are Assam's capital, Dispur, with an AQI of 64, and Tripura's capital, Agartala, with an AQI of 65. 'Satisfactory' air quality is indicated by that.

Of all the state capitals, Imphal, the capital of Manipur, has the highest AQI. The AQI for Imphal is 38.

Mizoram's Aizawl is the state capital with the second-best AQI. The capitals of Meghalaya and Arunachal Pradesh, Itanagar and Shillong, respectively, placed third and fourth. Shillong's AQI is 58, whereas Itanagar's is 56.

Notably, out of all the state capitals, only Imphal's air quality falls into the "good" category. Imphal, with an AQI of 38, would be the clear winner if clean air were the only criterion.
