Delhi's air quality on 24 October 2026 registered an Air Quality Index (AQI) of 191 (Moderate) — the best reading for this date in a decade, according to Delhi Environment Minister Manjinder Singh Sirsa. Excluding the Covid-19 period, this is the most favourable AQI recorded for 24 October in ten years, marking what officials describe as a significant milestone in the capital's battle against air pollution.

A Decade of Comparison

The year-on-year improvement is stark. The AQI on 24 October stood at 306 in 2024, dropped to 275 in 2025, and has now fallen further to 191 in 2026. That trajectory — a drop of over 100 AQI points in two years — points to a sustained, if still incomplete, improvement in the capital's air.

What the Government Said

Minister Sirsa attributed the improvement to a multi-pronged pollution control strategy. 'The improvement reflects the impact of sustained pollution mitigation measures, intensified enforcement and coordinated interventions by various government agencies to address the major sources of pollution across the capital,' he said. He credited the approach under Chief Minister Rekha Gupta, which combines field-level enforcement, regular inspections, district-level reviews, and technology-enabled monitoring.

Key Actions in the Last 24 Hours

The Delhi government and associated agencies undertook a series of concrete enforcement steps in the 24 hours preceding the announcement. These included:

• 9,883 vehicle challans issued to curb vehicular pollution
• 12,702 metric tonnes of waste removed from identified areas
• 1,075 km of roads covered through water sprinkling to control road dust
• 2,223 metric tonnes of construction and demolition (C&D) waste lifted
• 2,810 km of roads covered through mechanical sweeping

Why It Matters

Delhi consistently ranks among the world's most polluted capitals in the October-November window, when post-monsoon conditions, stubble burning in neighbouring states, and cooler temperatures trap particulate matter close to the ground. An AQI of 191, while still in the 'Moderate' category, represents a meaningful break from the 'Very Poor' and 'Severe' readings that have historically characterised this period. Notably, this is the first time in at least ten years that the city has avoided the 200+ AQI mark on this specific date outside of pandemic-induced lockdowns.

What Comes Next

Minister Sirsa reiterated that the anti-pollution campaign would continue 'in war mode,' with a focus on accountability, enforcement, and public participation. All concerned departments and agencies have been directed to maintain strict vigilance and take prompt action against violations. Whether the city can sustain this improvement as temperatures drop further through November — historically the worst month for Delhi's air — will be the real test of the measures now in place.
