Opinion | Delhi Has Every Pollution Control Policy - Except One That Works
Monday November 09, 2026Every November, Delhi performs the same ritual. We check the AQI before stepping outdoors, children are kept indoors, masks reappear, schools consider shutting, construction is restricted, and emergency meetings are convened. Politicians blame the weather, neighbouring states, farmers, or firecrackers. And then, as the season changes, the urgency d...

Monday October 19, 2026The clearest sign that Delhi is on a path to cleaner air would be a decline in the amount of paddy grown nearby, and therefore the acreage liable to be burned each year.
Don't Normalise Air Purifiers As Delhi Chokes | The Reason Why
Thursday December 11, 2025More than 90 cities in the world's top 100 polluting list are in India. With every passing year, the AQI is rising, reaching 'hazardous' levels.

Past episodes show that Delhi's AQI has often fallen after Stage IV of the plan was imposed. On 17 January 2026, the AQI stood at 400. It dropped to 192 within a week. In November 2023, it fell from 454 to 218 over the same period.
Mumbai's air pollution has surged past Delhi's levels, raising concerns about respiratory and heart health.
Data from the Daily AQI bulletin of the Central Pollution Control Board show that the 24-hour average air quality index in many cities across northern India is worse than in much of southern India.
On October 24, Mumbai's Air Quality Index (AQI) reportedly touched 322, placing it in the very poor category, while Delhi recorded 176.
The city recorded a maximum temperature of 31.4 degrees Celsius, 0.4 degrees below normal.
Mumbai's coastal location has long been considered an advantage in dispersing pollution. Yet, as haze settles over the skyline and air-quality readings fluctuate sharply across neighbourhoods, the city is confronting a problem that cannot be explained by its construction boom alone.
Use a True HEPA filter (H13 or H14 grade), which traps 99.97% of airborne particles down to 0.3 microns.
As air quality index levels drop across northern India, choosing the right mask is essential for respiratory health.
A preliminary study also highlights the substantial contribution of road dust to Mumbai's particulate pollution.
Mumbai's hazy skyline has renewed concerns over the sources of its air pollution. Research points to road dust, vehicle emissions and industrial activity, while questions over monitoring and enforcement are putting the city's pollution control measures under scrutiny.
