The national capital’s air quality has once again entered the ‘severe’ category for the first time this season, prompting authorities to enforce Stage 3 of the Graded Response Action Plan (GRAP). The move came after Delhi’s average Air Quality Index (AQI) shot up to 425, marking a sharp decline in atmospheric conditions across the city and its adjoining areas.
Delhi’s air quality hits alarming level
According to official data, multiple areas in Delhi recorded dangerously high pollution levels. Bawana topped the chart with an AQI of 462, followed by RK Puram (446), Patparganj (438), and Alipur (442). Anand Vihar logged 412, while Chandni Chowk recorded 416. These readings indicate heavy smog and particulate matter concentration across the city.
As per the Ministry of Environment, the city’s average AQI between January 1 and November 9, 2025, was 175 — a marginal improvement from 189 recorded during the same period last year. Concentrations of PM2.5 and PM10 stood at 75 µg/m³ and 170 µg/m³ respectively, compared to 87 µg/m³ and 191 µg/m³ last year.
Decline in farm fire incidents
The data also shows a significant drop in stubble-burning incidents in Punjab and Haryana — two major contributors to Delhi’s annual smog. Punjab reported 4,062 fire events between September 15 and November 9 this year, marking a 35.2% decline compared to 2024. Haryana saw an even sharper fall of 65.3%, with only 333 fire counts this year against 959 last year.
Authorities said the Commission for Air Quality Management (CAQM) continues to monitor the situation closely with state officials to ensure strict adherence to anti-pollution directives.

With GRAP-3 now in force, the following restrictions are being implemented across Delhi-NCR:
- Complete ban on non-essential construction and demolition activities, including open-air operations of Ready-Mix Concrete (RMC) plants.
- Ban on plying of BS-III petrol and BS-IV diesel cars.

- Restriction on inter-state diesel buses entering Delhi.
- Advisory for private companies to promote work-from-home or hybrid models.
- Schools up to Class 5 to shift to online mode to safeguard children from toxic air.
Essential projects such as metro, railways, sanitation, defence, and healthcare will continue under strict dust and waste management protocols.
