The Commission for Air Quality Management (CAQM) invoked Stage 1 of the Graded Response Action Plan (GRAP) across Delhi-NCR on Wednesday, 21 October, after the capital's air quality plunged into the ‘poor’ category. Delhi's AQI rose sharply from 179 on 20 October to 244 by 2 pm on 21 October, according to the CAQM. Forecasts by the India Meteorological Department and the Indian Institute of Tropical Meteorology indicate the AQI will remain ‘poor’ in the coming days.

Under GRAP-1, the use of coal and firewood in tandoors at hotels and restaurants is banned, and diesel generators are allowed only for emergency and essential services. Delhi Environment Minister Manjinder Singh Sirsa said mechanical road sweepers must cover 100 per cent of roads. The CAQM has directed all agencies across the NCR to intensify anti-pollution measures and monitor compliance. The sub-committee will review the situation periodically and decide if further stages are needed.
All six sources report the same development with near-identical framing: the CAQM invoked GRAP Stage 1 on 21 October after Delhi's AQI rose from 179 on 20 October to 244 by 2 pm. Four sources (ABP Live, India TV, Economic Times, Times of India) quote Minister Manjinder Singh Sirsa, the others (The Hindu, The Hindu Business Line) rely on the CAQM statement. The only substantive difference is the AQI figure used for triggering: ABP Live cites 233 at 9 am, while the others use 244 at 2 pm. No source is critical of the government or the CAQM, all present the decision as a standard procedural response to forecast data. The coverage is uniform straight reporting from wire copy. The next concrete step is the CAQM sub-committee's periodic review of air quality and forecasts before any additional GRAP stage is invoked.
