The city has seen a sharp fall in fine particle pollution (PM2.5) over the past decade, dropping by more than half from 198.44 micrograms µg/m³ in 2015-16 to 91.7 in 2026-27, a decline of nearly 54% over the decade.

The report says Gurgaon’s PM2.5 pollution levels dropped by nearly 54% between 2015 and 2026, falling from about 198 to 92 micrograms per cubic metre. Most of the improvement happened before 2020, but progress has slowed sharply since then.

HSPCB advisory targets dust and particulate pollution in high-rise clusters, with RWAs asked to run rooftop sprinklers during poor air quality phases.

Gurugram’s air quality appears slightly better mainly because many monitoring stations are located in relatively cleaner and greener areas, where trees help disperse pollutants.

Gurgaon is expected to witness dense haze following Diwali as weather conditions turn unfavourable for pollutant dispersion. According to the IMD, wind speeds will drop below 8 kmph, and calm conditions may trap smoke, causing AQI levels to deteriorate sharply after the festival.
