As the nation lit up for Diwali on Monday, Delhi’s skies were blanketed by a thick haze, with most of its air monitoring stations flashing alarming red. According to official data from the Central Pollution Control Board (CPCB), 34 of the 38 stations in the city recorded air quality in the ‘very poor’ to ‘severe’ range.
Air Quality Slips Further On Diwali
Delhi’s 24-hour average Air Quality Index (AQI), measured at 4 pm each day, stood at 345 — worse than Sunday’s 326. The CPCB’s SAMEER app showed that four key stations — Dwarka (417), Ashok Vihar (404), Wazirpur (423) and Anand Vihar (404) — crossed into the ‘severe’ zone, while around 30 others hovered in the ‘very poor’ range.
Data from the Decision Support System (DSS) revealed that vehicular emissions contributed about 15.6 per cent of the city’s pollution on Monday, while industrial sources made up 23.3 per cent.
The Commission for Air Quality Management (CAQM) had already invoked Stage II of the Graded Response Action Plan (GRAP) on Sunday following predictions by the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM). Officials warned that pollution levels could worsen further on Tuesday and Wednesday.
Diwali 2025: Green Crackers Allowed, But Smoke Lingers
The Supreme Court had earlier permitted the sale and bursting of certified eco-friendly green crackers in Delhi-NCR between 6 am and 7 pm and again from 8 pm to 10 pm on Diwali eve and the festival day. Despite the regulated window, firecrackers were widely used across the national capital on Monday night, worsening the air quality.
Chief Minister Rekha Gupta urged citizens to protect Delhi from pollution by sticking to green crackers and celebrating through traditional means such as lighting diyas, making rangolis, and sharing sweets.
People were seen bursting crackers in the national capital to celebrate the festival.

Diwali 2025: Nation Lights Up, Leaders Extend Greetings
Across India, homes and streets were decked with lamps and colourful lights. Prime Minister Narendra Modi extended Diwali greetings, wishing that the festival “illuminate our lives with harmony, happiness and prosperity; and a spirit of positivity prevail all around us.”
The Prime Minister celebrated Diwali with naval personnel aboard INS Vikrant off the Goa coast. “Today, on one side, I have infinite horizons and infinite sky, and on the other side, I have this giant, INS Vikrant, embodying infinite powers. The glow of the sun’s rays on the ocean’s waters is like the Diwali lamps lit by brave soldiers,” he said.
Earlier in the day, Modi performed yoga on the deck, witnessed a steampast and flypast, addressed naval personnel, and distributed sweets. Later, he met President Droupadi Murmu and Vice President C P Radhakrishnan at Rashtrapati Bhavan to exchange greetings.
In a post on X (formerly Twitter), President Murmu stated: “On the auspicious occasion of Diwali, I extend my greetings and best wishes to all Indians residing in India and abroad.”
Leader of the Opposition Rahul Gandhi marked the day differently, sharing a video of himself preparing imarti and besan laddoo at Old Delhi’s famed Ghantewala sweet shop. He wished people on Diwali and asked them to share how they were making the festival special.
