Gurgaon was India's astir polluted metropolis successful March, with Haryana accounting for 4 of the country's 10 astir polluted cities, according to a caller study by the Centre for Research connected Energy and Clean Air (CREA).
The different cities successful the apical 10 polluted database for March were Bahadurgarh, Faridabad, Singrauli, Mandideep, Ghaziabad, Manesar, Bhiwadi, Noida and Nandesari. For the full fiscal twelvemonth 2025-26, Ghaziabad was the astir polluted city.
"Gurgaon was India's astir polluted metropolis successful March, with a monthly mean PM2.5 of 116 μg/m3. Haryana accounted for 4 of India’s apical 10 astir polluted cities, followed by 2 cities each from Madhya Pradesh and Uttar Pradesh, and 1 each from Rajasthan and Gujarat.”
"Haryana had the highest fig of cities exceeding the National Ambient Air Quality Standards (NAAQS), with 9 retired of 24 signaling PM2.5 higher than the NAAQS. That was followed by Uttar Pradesh with 8 retired of 21 cities exceeding the NAAQS," the study said.
An investigation of India's National Clean Air Programme (NCAP), which evaluates PM10 reductions connected a fiscal twelvemonth basis, showed that conscionable a fewer cities met the NCAP targets aft 7 years of implementation.
"Among the cities showing improvement, 9 cities successful Uttar Pradesh recorded reductions of implicit 40 per cent successful PM10 levels compared to the NCAP baseline twelvemonth (2017-18). Similar reductions were besides reported successful 3 cities successful Maharashtra and 2 cities each successful West Bengal, Uttarakhand, Punjab, and Rajasthan, and 1 metropolis each successful Tamil Nadu, Jharkhand, Nagaland, Jammu & Kashmir, Chhattisgarh, Bihar and Assam," the study said.

Dehradun (Uttarakhand) reported the largest simplification successful PM10 levels astatine 75 per cent compared to 2017-18, portion Visakhapatnam (Andhra Pradesh) recorded the highest summation astatine 73%. Delhi saw a 17% simplification successful PM10 levels implicit the aforesaid period.
"Many cities are inactive acold from gathering the revised NCAP targets, and immoderate person adjacent seen rising contamination levels, which is simply a superior concern. As the programme moves into its adjacent phase, determination is an accidental to basal interventions connected robust, science-based solutions, with backing directed towards the large contamination sources identified successful each region," said Manoj Kumar, expert astatine CREA.
"In caller years, much cities person slipped into non-attainment status, which means that revising NCAP to see emerging hotspots, adopting a determination approach, and enforcing stricter emanation standards volition each beryllium essential," helium added.
