Smog tower’s current efficiency ‘half’ of Delhi Government claim
The Hindu
Authorities say if needed they will enhance the entire system to achieve set goals
On October 1 this year, the Delhi Government said that a smog tower can clean up to 80% of polluted air, citing a preliminary report. However, two months later, the percentage of pollution being reduced is only 34%-43%, according to six readings between November 30 and December 1 accessed by The Hindu.
The smog tower at Connaught Place, a pilot project installed at a cost of ₹20 crore, was inaugurated on August 23 by Chief Minister Arvind Kejriwal, who had said similar towers will be built in other parts of the city if the results are satisfactory.
A few weeks later, Environment Minister Gopal Rai’s office released a statement that read: “The preliminary report of the smog tower installed by the Kejriwal Government was released today (October 1). The report has revealed that the smog tower is cleaning up to 80% of the air.”

Tamil Nadu Minister for Rural Development I. Periyasamy told the State Assembly on Tuesday (April 8, 2025) that measures were underway to provide road connectivity to Kadamban Kombai, a tribal hamlet located deep inside the forest, in Nellithurai panchayat, Coimbatore district, at a cost of ₹1.62 crore.
