Delhi-NCR to get 55 new air quality monitoring stations by year-end, total to reach 157
Delhi and the National Capital Region (NCR) are set to expand their air quality monitoring network significantly by adding 55 new continuous ambient air quality monitoring stations (CAAQMS) by the end of the year. The expansion, announced by the Union environment ministry and the Commission for Air Quality Management (CAQM), aims to meet a coverage standard of one station per 25–50 square kilometers. Currently, there are 102 operational stations across Delhi and NCR, and the addition of 55 more will bring the total to 157. The project seeks to address gaps in air quality data, especially in underserved areas. Final locations for the new stations are still under determination, but some are expected to begin generating data during the upcoming winter season.
Toxic Delhi has ranked ahead of Srinagar and Bengaluru in the Centre's Swachh Vayu Sarvekshan 2026, a clean-air assessment that considers pollution-control efforts and implementation rather than just air quality. Delhi secured the 21st position among cities with populations over 10 lakh, while Srinagar and Bengaluru came in at 26th and 32nd, respectively. Lucknow topped the ranking with 198 points, narrowly edging out Indore, which has been the cleanest city in India for eight consecutive years. The Swachh Vayu Sarvekshan, conducted under the National Clean Air Programme (NCAP) by the Union Environment Ministry, evaluates cities based on factors including road-dust control, solid-waste management, reduction of vehicular and industrial emissions, construction-waste management, and public awareness. The survey includes 130 NCAP cities divided into three population categories. Delhi's performance in the 2026 survey contrasts with its 2025 ranking, where it placed 32nd with a score of 157.3. In 2026, Delhi scored 172 and shared the 21st rank with Visakhapatnam. Srinagar scored 162.6 and finished 26th, while Bengaluru received 152.6 points and ranked 32nd. Patna outperformed Delhi, securing 16th place with 178 points. Despite its high ranking, Delhi continues to face severe air quality issues, especially during winter. Its AQI often exceeds 400, entering the "severe" category, and sometimes surpasses 450. Even in 2025, described as Delhi's best year for particulate pollution since 2018, the city's annual average PM10 concentration reached 198 micrograms per cubic metre, and PM2.5 levels hit 97 micrograms per cubic metre, both well above the national standards of 60 and 40 micrograms per cubic metre, respectively. The capital's air quality worsened significantly during the 2025-26 winter, prompting authorities to invoke Stage IV of the Graded Response Action Plan in January 2026 after air pollution reached critical levels. Separately, the ambient air quality monitoring network across Delhi-NCR is set to expand significantly. Officials confirmed plans to add 55 new continuous ambient air quality monitoring stations (CAAQMS) by the end of 2026, increasing the total number of operational stations from 102 to 157. This expansion aims to meet the coverage criteria set by the Commission for Air Quality Management (CAQM) and the Union environment ministry, ensuring a station for every 25-50 square kilometres. As of February 2026, Delhi-NCR had 84 stations, with 40 in Delhi, 22 in Haryana, 18 in Uttar Pradesh, and four in Rajasthan. The additional stations will be distributed across Delhi and NCR towns, with specific locations still under determination. Some stations are already in the tendering phase and are expected to provide air quality data by winter. The expansion seeks to address gaps in the current monitoring network, particularly in areas with limited or no continuous monitoring.

India's Union Environment Ministry released the Swachh Vayu Sarvekshan 2026, a clean-air ranking that evaluates cities based on their pollution-control efforts and implementation rather than just air quality. Despite Delhi's frequent severe air-quality index (AQI) readings exceeding 400 during winter, it ranked 21st among cities with populations over 1 million, surpassing Srinagar (26th) and Bengaluru (32nd). Lucknow topped the list with 198 points, narrowly edging out Indore, which had previously held the title of India's cleanest city. The ranking considers factors such as road dust control, waste management, emission reduction, and public awareness initiatives. Delhi improved from its 2025 ranking of 32nd with a score of 157.3 to 172 points in 2026.
