An investigation of the Air Quality Index (AQI) crossed large Indian cities from 2015 to November 2025 has revealed that Bengaluru has the cleanest aerial among metros.
However, the findings said that though Bengaluru shows the champion aerial quality, it is inactive not “safe.” According to Climate Trends AQI information crossed large Indian cities from 2015 to November 2025, nary of the apical municipality centres successful India tin beryllium considered “safe” successful presumption of aerial quality.
Climate Trends is simply a research-based consulting and capableness gathering initiative.
“AQI remains betwixt 65 and 90 astir years, though comparatively cleaner, these values inactive transcend the ‘Good’ category, but accelerated urbanisation and conveyance maturation forestall the metropolis from falling into harmless range,” states the cardinal uncovering for Bengaluru.
Delhi astir polluted
It added that Delhi remains the astir polluted metropolis passim the survey period, maintaining persistently precocious AQI values from peaks supra 250 (2016) to levels inactive adjacent 180 successful 2025.
“While determination is insignificant year-to-year fluctuation, the metropolis ne'er approaches harmless thresholds and continues to acquisition chronic mediocre aerial prime driven by vehicular emissions, concern activity, seasonal harvest burning, and geographic factors,” it added.

“Southern and occidental cities specified arsenic Bengaluru, Chennai, Mumbai, and Pune execute comparatively amended but inactive neglect to execute genuinely steadfast air-quality ranges. These findings item the continued interaction of postulation emissions, concern activity, seasonal factors, and accelerated urbanisation crossed the country,” it said.
Palak Balyan, probe lead, Climate Trends, said, “Moving to different metropolis for cleaner aerial isn’t a existent solution, and astir radical can’t spend to bash it anyway. What India needs is sustained, long-term, science-based argumentation betterment backed by genuine governmental volition to instrumentality pugnacious decisions”.
He added that aerial contamination affects everyone, but not equally: radical who walk much clip outdoors, similar thoroughfare vendors, sanitation staff, transport workers, and operation workers, are impacted the most.
