Delhi's Jan-Nov average AQI lowest since 2018, barring lockdown year: CAQM

Delhi recorded its lowest January-November average air quality index (AQI) since 2018, barring the Covid lockdown year of 2020, the Commission for Air Quality Management (CAQM) said on Sunday. The average AQI for the period this year was 187, compared to 201 in 2024, 190 in 2023, 199 in 2022, 197 in 2021, 172 in 2020, 203 in 2019 and 213 in 2018, the CAQM said in a statement. Only three days saw the daily average AQI exceed 400 (severe category) between January and November this year. There were 11 such days in 2024, 12 in 2023, four in 2022, 17 in 2021, 11 in 2020, 16 in 2019 and 12 in 2018. Not a single day has crossed the 450 mark so far this year, the statement said. PM2.5 concentration for the period up to November 27 was the lowest since 2018 and at par with 2020. The average stood at 85 micrograms per cubic metre this year, against 98 in 2024, 90 in 2023 and 2022, 95 in 2021, 85 in 2020, 99 in 2019 and 103 in 2018. PM10 levels were also the lowest for the corresponding peri

Road dust emerges as major pollutant in Delhi; 35 high-dust spots located

Road dust remains a major driver of particulate pollution in the capital, the Commission for Air Quality Management (CAQM) said on Sunday after its flying squads inspected 321 road stretches across Delhi under Operation Clean Air. The inspections, carried out on Saturday, were meant to check how much dust had settled on the roads and whether cleaning, sweeping and dust-suppression measures by the Municipal Corporation of Delhi (MCD), New Delhi Municipal Council (NDMC), and Central Public Works Department (CPWD) were working on the ground. Out of the 321 stretches checked, 35 showed high levels of visible dust, 61 had moderate dust, 94 recorded low dust and 131 had no visible dust. CAQM in a statement said the results highlight once again that road dust remains a major contributor to Delhi's particulate matter, especially in winter, and that regular mechanical sweeping, timely removal of collected dust, pavement upkeep, and water-sprinkling are essential. MCD had the largest number

PIL in Delhi HC seeks urgent action to tackle hazardous air pollution

A PIL filed in the Delhi High Court has sought urgent steps to control hazardous air pollution levels in the national capital. The plea said over the past several years, the ambient air quality in Delhi has deteriorated drastically, with AQI frequently entering the 'very poor', 'severe' and 'hazardous' categories, especially during winter. The increased pollution has resulted in persistent and serious health issues among residents, including children, senior citizens and persons with pre-existing ailments, it said. The petition has been filed by Greater Kailash-II Welfare Association, which has urged the court to order urgent, effective and scientific measures, both immediate and long-term, to control the city air pollution. The plea said the authorities, which remained "virtually inactive" as the air quality steadily deteriorated, chose to issue "Stage III - steps to be taken" only after the AQI had crossed its critical level. The government confined itself to merely prescribing

Stubble burning incidents decline in Delhi-NCR, Punjab, Haryana: Agri secy

Stubble burning incidents in Delhi-NCR, Punjab and Haryana have reduced this year due to government support for farm machinery and other measures, Agriculture Secretary Devesh Chaturvedi said on Monday. The government has provided farmers with relevant equipment and necessary interventions to tackle the problem, Chaturvedi told reporters on the sidelines of an event. "Certainly...because of the policy of providing machineries and in-situ and ex-situ measures, the incidents of stubble burning in Delhi-NCR, Punjab and Haryana have reduced," he said. There have hardly been incidents of stubble burning in the last ten days, he said. Stubble burning by farmers in northern India after harvesting has been a major contributor to severe air pollution in Delhi and surrounding areas during winter months. When asked about other pollution sources, Chaturvedi said other ministries were better placed to comment. "If there are other reasons (for pollution), other ministries are best to say," he
