Delhi's Air Quality Milestone: 79 'Good' Days in 2025, Severe Pollution Hits Low

Delhi achieved a significant milestone in 2025 with 79 days recording 'Good' or 'Satisfactory' air quality, the highest number since the pandemic year of 2020. Concurrently, the city experienced only 8 days of 'Severe to Severe+' pollution, marking the second-lowest count since 2018, a trend attributed to sustained policy measures. However, the report contrasts with current conditions, as dense fog and severe pollution enveloped the capital, with an overall AQI of 384 and several stations recording levels above 410. This highlights the persistent seasonal challenge of winter smog against a backdrop of gradual annual improvement.

Delhi records 79 'Good' AQI days in 2025, severe pollution drops to second-lowest since 2018: CAQM

Delhi records 79 days with 'Good' AQI in 2025, marking the second-lowest number of severe pollution days since 2018, despite ongoing winter smog challenges.

"a record 79 days during 2025 with the AQI of 100 or below - Commission for Air Quality Management"

New Delhi, December 31

The Commission for Air Quality Management in NCR and Adjoining Areas, since its inception in 2021, through a series of Directions/Advisories and Orders, has initiated various policy measures and field actions to abate air pollution in Delhi-NCR, an official press release said.

Continued, concerted and persistent efforts of all the stakeholders around the year in 2025 have further helped to improve the general air quality in Delhi as is evident from a record 79 days during 2025 with the AQI of 100 or below, i.e. in 'Good' and 'Satisfactory' categories, which is lower than only the Covid year 2020. The year 2025 recorded the second-lowest number of "Severe to Severe+" AQI days, i.e. 8 such days, since 2018.

Dense fog enveloped several parts of the national capital and adjoining areas of the National Capital Region (NCR) on Wednesday morning, severely reducing visibility and disrupting normal movement across key stretches.

Visuals from Ghaziabad's Indirapuram, Noida's Botanical Garden Metro Station, and Delhi's Akshardham area showed thick layers of fog blanketing roads and residential areas, with vehicles moving at a slow pace as visibility dropped sharply. Similar conditions were observed across several areas of Noida, where dense fog continued to affect early-morning commuters.

According to data from the Central Pollution Control Board (CPCB), Delhi's overall Air Quality Index (AQI) was recorded at 384 at 7 am, placing it in the 'very poor to severe' category.

Several air quality monitoring stations across the city reported alarming AQI levels. Anand Vihar recorded an AQI of 452, while ITO stood at 426, RK Puram at 411, and Chandni Chowk at 419, all falling under the 'severe' category. Dwarka Sector 8 also recorded a high AQI of 414.

Other areas witnessed slightly lower but still hazardous air quality levels. IGI Airport (Terminal 3) recorded an AQI of 334, while Najafgarh stood at 331 and Aya Nagar at 321, all categorised as 'very poor'.

The data is promising, but reading about AQI 452 in Anand Vihar today puts things in perspective. We have good days, but the severe days are still dangerously high. The fight is far from over. Need stricter enforcement on construction dust and industrial pollution.

As a daily commuter from Noida, the fog and pollution combo this morning was brutal. Visibility was near zero. While the yearly trend looks better, these winter spikes are a health emergency every year. Public transport needs a massive boost to get cars off the road.

Living near RK Puram, we still have to keep air purifiers running most days. It's good to see progress in the annual report, but the headline number feels distant when your local station reads 'Severe'. Consistent, localized action is key.

Respectfully, while the commission's work is noted, comparing to the Covid year 2020 sets a low bar. The real test is beating pre-2020 numbers. The reduction in 'Severe' days is the most positive takeaway here. More green cover and waste management please!

My child's asthma attacks have reduced slightly this year, which aligns with this data. Every 'Good' AQI day matters for our health. Hope the authorities continue the push for cleaner fuels and monitor the hotspots like ITO and Chandni Chowk more closely.
