Delhi Air Quality

Delhi recorded the lowest yearly average of particulate matter PM2.5 and PM10 in 2025, barring the Covid year i.e. 2020, according to the economic survey of 2025-26 tabled in the Delhi Assembly by Chief Minister Rekha Gupta on Monday. The report, which quotes Delhi Pollution Control Committee's (DPCC) Continuous Ambient Air Quality Monitoring System (CAAQMS) data, the yearly average of PM10 in 2025 was 209 (measured in micrograms per cubic metre) and that of PM2.5 was 100. This was the lowest since 2015, before which data is not available. In 2020, which was the year of the global Covid pandemic, PM10 yearly average had dropped to 187 but PM2.5 remained at 101, one unit higher than 2025. According to the DPCC data provided, the yearly average of PM10 and PM2.5 in 2024 were 225 and 110 respectively, in 2023 were 219 and 106. The PM10 and PM2.5 yearly average were 223 and 103 in 2022, and were 221 and 113 in 2021, respectively. The report quoted that the year-wise annual mean ambien

Delhi breathed easier on Monday after 157 days, as the city's air quality improved to 119 in the 'moderate' category, while the city recorded a maximum temperature of 32.2 degrees Celsius. The 24-hour average Air Quality Index (AQI) stood at 119, the lowest recorded since October 9, 2025, when the AQI had stood at 99 in the same category. At 9 am on Monday, the AQI stood at 97 in the 'satisfactory' category, according to data from the Central Pollution Control Board (CPCB). The improvement came after the city experienced light rain on Sunday. According to the CPCB classification, an AQI between zero and 50 is considered 'good', 51 to 100 'satisfactory', 101 to 200 'moderate', 201 to 300 'poor', 301 to 400 'very poor', and 401 to 500 'severe'. The improvement in air quality came after many parts of Delhi and the surrounding region on Sunday received light rain, triggered by a western disturbance. The drizzle brought respite from the rising heat and helped disperse pollutants in the

Delhi was the most polluted city during 2024-25, recording the highest annual PM2.5 levels and extended periods of "severe" air quality in winter while Patna was the second-most polluted city, according to a new analysis by Climate Trends. Climate Trends is a research-based consulting and capacity-building initiative that aims to bring greater focus on issues of environment, climate change and sustainable development. Based on Central Pollution Control Board (CPCB) air quality monitoring data, this report analysed how meteorological conditions influence the persistence of PM2.5 pollution across six major Indian cities such as Delhi, Patna, Kolkata, Mumbai, Chennai and Bengaluru. Using CPCB air quality data (2024-2025) combined with meteorological clustering, the study distinguished emission-driven pollution from weather-driven variability. "Delhi continues to face the most severe pollution crisis nationally with the highest annual average PM2.5 levels and the longest stretches of ..
