Delhi-NCR records 'poor' air quality as AQI rises to 292, with dense fog affecting visibility and causing flight delays, travel disruptions

Union Science and Technology Minister Jitendra Singh on Monday inaugurated a laboratory to test and calibrate equipment to monitor air pollution, one of the very few such facilities in the world. Singh inaugurated the National Environmental Standard Laboratory at the CSIR-National Physical Laboratory (NPL) premises here, and described it as a critical step towards strengthening India's environmental governance framework. Singh said the facility will reduce India's dependence on foreign certification agencies, save foreign exchange, shorten turnaround time for calibration, and enhance investor confidence in the country's rapidly expanding solar sector. The minister also inaugurated the National Primary Standard Facility for Solar Cell Calibration (Solar Energy Complex), terming it a "future-ready facility" that places India among a select group of global leaders in photovoltaic measurement standards. Addressing the 80th Foundation Day celebrations of Centre for Scientific and ...

Delhi saw a marginal respite in air quality on Monday as the 24-hour average Air Quality Index (AQI) improved to 244, in the poor' category, after lingering in the very poor' range a day earlier. Data from the Central Pollution Control Board's Sameer app showed that four stations recorded very poor' air quality, with Chandni Chowk logging the worst AQI at 321, while 25 stations remained in the poor' category and nine recorded moderate' air quality. 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 Decision Support System indicated that Delhi's pollution load was led by transport at 13.7 per cent, followed by peripheral industries at 11.4 per cent, residential sources at 3.3 per cent, construction at 1.2 per cent and waste burning at one per cent. Among NCR districts, Jhajjar contributed the highest at 19.6 per cent, followed by Sonip

Delhi's air auality index eased to 260 on Monday, but fog and trapped pollutants kept much of Delhi in the 'poor' and 'very poor' category

As much as 65 per cent of Delhi's air pollution in 2025 originated from outside the city, mainly from other NCR districts, while local sources accounted for the remaining 35 per cent, a study said. According to an analysis by the Centre for Research on Energy and Clean Air (CREA), accessed by PTI, winter-period inputs from the Decision Support System indicated that pollution transported into the national capital outweighed emissions generated within the city during 2025. Winter-period source attribution figures showed that vehicular emissions accounted for nearly half of Delhi's local PM2.5 pollution, surpassing contributions from industry, construction and other combustion sources, even as transboundary pollution remained the dominant overall contributor. "Transboundary pollution from NCR districts and neighbouring states plays a major role in Delhi's air pollution. Delhi's geographical location also makes it vulnerable, as northerly and north-westerly winds carry polluted air from

Air quality in Delhi improved slightly with AQI improving to 'poor' and prompting CAQM to ease some curbs. However, fog and low visibility are expected to cause some travel disruptions

CAQM revokes Grap III curbs across Delhi-NCR after AQI improves to 'poor' levels, aided by strong winds. However, restrictions under Grap I and II will continue to remain in force across NCR

The Delhi Legislative Assembly will re-convene on January 5, with the four-day session focussing on the pollution crisis in the national capital and scrutiny of three CAG reports, Minister Kapil Mishra said on Tuesday. The Art, Culture and Tourism minister said the government will table a proposal on pollution and table three CAG reports one each on corruption in 'Sheeshmahal,' the functioning of the Delhi Jal Board (DJB), and Delhi government-run universities. The term 'Sheeshmahal' was coined by the BJP to point out the alleged opulence of the 6, Flagstaff Road residence of the ex-Delhi chief minister Arvind Kejriwal. "There is a very detailed report on the functioning of DJB till the year 2022, it has all the details of all the irregularities which caused the sewage system of the city to collapse," Mishra said at a press conference. "The CAG report on the irregularities in the functioning of universities governed by the Delhi government will be tabled, and all the corruption wh

The Delhi government is exploring a potential collaboration with IIT Kanpur to leverage Artificial Intelligence to identify pollution sources at a granular level and assess their impact, officials said on Sunday. The environment department is all set to deliberate on the roadmap for collaboration, institutional mechanisms and phased implementation, an official statement said. Speaking on the initiative, Delhi Environment Minister Manjinder Singh Sirsa said, "We are moving towards a model where decisions are driven by real-time data, source identification and measurable outcomes, not reactive measures." The proposed collaboration aims to strengthen Delhi's ability to identify pollution sources at a granular level, assess their impact, and enable targeted, timely interventions across sectors. The emphasis is on building systems that can monitor, analyse, forecast and guide action on a continuous basis, he said. A key pillar of this approach is dynamic source apportionment, which wil
