'Pollution in Delhi nearly doubled in Nov, becoming 4th most polluted city'

Delhi's air pollution nearly doubled in November, pushing the national capital to the fourth spot among the most polluted cities in the country, according to a report. A report released by the Centre for Research on Energy and Clean Air (CREA) on Saturday highlighted that while the impact of stubble burning on Delhi's air quality was significantly lower compared to last year, pollution levels in the city remained severe. Delhi ranked as the fourth most polluted city in the country in November, recording a monthly average PM2.5 level of 215 micrograms per cubic metre -- nearly double its October average of 107 micrograms per cubic metre. The national capital witnessed 23 'very poor' days, six 'severe' days and one 'poor' day during the month. Despite the deteriorating air quality, the contribution of stubble burning averaged only 7 per cent in November, compared to 20 per cent last year. Peak stubble-burning contribution touched 22 per cent, significantly lower than the 38 per cent

Delhi chokes as air quality stays in 'very poor' band, with AQI at 330

A thick blanket of pollution hung over the capital on Saturday as Delhi's air quality stayed locked in the 'very poor' category, with the 24-hour average AQI settling at 330. Among the 40 monitoring stations, 31 stations remained in the 'very poor' levels in the evening, with Nehru Nagar reporting the highest AQI at 369, according to CPCB's Sameer App. Earlier, Delhi woke to another choking morning with the AQI at 335 at 9 am. A total of 36 stations were in the 'very poor' category, with Mundka recording the worst levels at 387. According to the Central Pollution Control Board (CPCB), an AQI between 0 and 50 is 'good', 51 to 100 'satisfactory', 101 to 200 'moderate', 201 to 300 'poor', 301 to 400 'very poor' and 401 to 500 'severe'. According to the Decision Support System for Delhi's air quality management, transport within the city remained the highest local contributor at 14.8 per cent, followed by industries in Delhi and surrounding areas at 7.3 per cent, residential sources at

Air pollution a legacy problem we inherited, says Delhi CM Rekha Gupta

Calling the national capital's air pollution woes a legacy problem, Delhi Chief Minister Rekha Gupta on Saturday assured that her government has been actively working for the past 10 months to address these issues. Speaking at the Hindustan Times Leadership Summit, Gupta highlighted that issues like pollution, garbage mountains, and broken roads were legacy issues and her government is working to tackle them through sustained efforts. She also referred to the clean-up of the Yamuna river as a "big project", stating that her administration is working daily to rejuvenate it. The rapid population growth in Delhi and the exponential increase in vehicles have contributed to rising pollution levels, Gupta pointed out, adding that several factors, including dust, vehicular emissions, and open burning, contribute to the pollution crisis. "It also matters what steps were taken by the previous government. Our government has taken all the steps needed to tackle pollution, which were not taken

No tampering possible in calculation, monitoring of air quality data: CPCB

The Central Pollution Control Board (CPCB) on Wednesday rejected allegations of manipulation of air quality data and said the monitoring stations are automated and no human intervention is possible in calculation and monitoring. Delhi government has been accused of spraying water around air-quality monitoring stations to lower dire readings and even switching them off during key pollution periods - for instance, when firecrackers increased the pollution load during Diwali in October. "The monitoring and data collection is automated... the stations generate data every 15 minutes and AQI is calculated every hour, following which the average AQI is generated. These stations are not manual, and hence any kind of human intervention or manipulation is not possible," CPCB Chairman Vir Vikram Yadav told reporters here. Responding to a query about allegations of sprinkling of water around monitoring stations to manipulate air quality data, Yadav said, "The monitoring stations have been set u

Delhi-NCR industries ordered to install emission monitors or risk closure

Amid continuing hazardous air quality, the Centre on Wednesday ordered Delhi-NCR authorities to crack down on highly polluting industries that miss the December 31 deadline to install real-time emission monitoring systems and air pollution control devices. The central government also directed Delhi-NCR states to finalise their 2026 air pollution control plans within this month. The decisions were taken at a review meeting chaired by Union Environment Minister Bhupender Yadav. Central Pollution Control Board Chairperson Vir Vikram Yadav said 2,254 highly polluting industries in Delhi-NCR have not yet installed and connected their Online Continuous Emission Monitoring Systems (OCEMS) to the CPCB server. "Strict action, including closure, will be taken against industries that do not meet the December 31 deadline," he said. All medium and large red-category units in the food and food processing, textile and metal processing sectors in Delhi-NCR are mandated to install OCEMS for real-t
