Nearly 44% Indian cities look chronic aerial pollution, indicating a structural occupation driven by persistent emanation sources alternatively than short-term episodes, an investigation by the Centre for Research connected Energy and Clean Air (CREA) has found. However, lone 4% of these cities are covered nether the National Clean Air Programme (NCAP), the study said.
Using outer data, CREA assessed PM2.5 levels successful 4,041 Indian cities. “Out of 4,041, astatine slightest 1,787 cities exceeded the nationalist yearly PM2.5 modular each twelvemonth crossed 5 caller years (2019-2024), excluding the COVID-affected twelvemonth of 2020. This means astir 44% of Indian cities look chronic aerial pollution, indicating a structural occupation driven by persistent emanation sources alternatively than short-term episodes,” the study said.
The PM2.5 appraisal for 2025 ranks Byrnihat (Meghalaya), Delhi, and Ghaziabad (Uttar Pradesh) arsenic India’s apical 3 astir polluted cities with yearly concentrations of 100 µg/m³, 96 µg/m³, and 93 µg/m³, respectively.
Noida is the 4th connected the list, followed by Gurugram, Greater Noida, Bhiwadi, Hajipur, Muzaffarnagar, and Hapur.
Many cities extracurricular the nett of programme
“Yet, India’s flagship NCAP covers lone a fraction of this burden. Just 130 cities were included nether NCAP, and lone 67 overlap with the 1,787 persistently non-attainment cities. As a result, NCAP presently addresses lone 4% of India’s chronically polluted cities, leaving the immense bulk extracurricular targeted cleanable aerial action,” it added.
Non-attainment cities are municipality areas identified by the Central Pollution Control Board (CPCB) that consistently neglect to conscionable the National Ambient Air Quality Standards (NAAQS) implicit respective years.
Most polluted regions successful U.P.
The study noted that Uttar Pradesh tops the database with 416 non-attainment cities, followed by Rajasthan (158), Gujarat (152), Madhya Pradesh (143), Punjab and Bihar (136 each) and West Bengal (124).
Out of 130 NCAP cities, 28 inactive deficiency continuous ambient aerial prime monitoring stations (CAAQMS), and among the 102 cities with stations, 100 cities reported 80% oregon higher PM10 levels.
“Progress connected PM10 power remains mixed. Twenty-three cities person achieved the revised 40% PM10 simplification target, 28 cities person recorded 21-40% reduction, 26 cities amusement humble improvements of 1-20%, portion 23 cities person successful information experienced an summation successful PM10 levels since the programme’s inception,” the study said.
“For PM10, Delhi tops the database with an yearly mean of 197 µg/m³, 3 times the nationalist standard. Ghaziabad and Greater Noida travel with averages of 190 µg/m³ and 188 µg/m³, respectively.
Rajasthan has the highest fig of cities successful the apical 50 successful presumption of PM10 concentration, 18 successful total, followed by Uttar Pradesh (10), Madhya Pradesh (five), and Bihar and Odisha (four each), the study said.
According to Manoj Kumar, India Analyst, CREA, strengthening the country’s aerial prime governance done targeted, science-based reforms whitethorn beryllium the lone mode forward.
“This means prioritising PM2.5 and its precursor gases (sulphur dioxide and nitrogen dioxide) implicit PM10, revising the database of non-attainment cities nether NCAP, mounting stricter emanation standards for industries and powerfulness plants, allocating backing based connected root apportionment studies, and adopting an airshed-based attack to code aerial contamination astatine a determination scale,” helium said.
Since the programme’s inception, ₹13,415 crore has been released nether the NCAP and 15th Finance Commission grants, of which ₹9,929 crore (74%) has been utilised.
Road particulate absorption accounts for 68% of spending, followed by transport (14%) and discarded and biomass burning (12%), portion industries, home substance use, nationalist outreach (each little than 1%), and capableness gathering and monitoring (3%) received constricted allocations.
