Delhi-NCR pollution: How GRAP Stage 1 curbs can protect your heart and lungs
On October 21, 2026, the Commission for Air Quality Management (CAQM) activated Stage 1 of the Graded Response Action Plan (GRAP) across the Delhi-NCR region after the Air Quality Index reached 244, classifying the air as poor. This activation followed the conclusion of Dussehra celebrations and marks the first instance of poor air quality recorded for the current season. The implemented measures include mechanized road sweeping, water sprinkling, strict dust control at construction sites, and bans on open waste burning to curb emissions of particulate matter like PM2.5 and PM10. Medical experts emphasize that while these early interventions cannot instantly render polluted air safe, they are critical for preventing further deterioration and reducing cumulative exposure. Physicians warn that fine particles pose significant risks to both respiratory and cardiovascular systems, potentially triggering inflammation and increasing strain on the heart even in individuals who do not experience immediate symptoms.
The Commission for Air Quality Management imposed Stage I of the Graded Response Action Plan across the Delhi-National Capital Region on Wednesday, citing a sharp decline in air quality. The directive followed the capital’s Air Quality Index rising to 244 at 2 p.m., moving the region from the moderate category into the poor classification. This marks the first instance of poor air quality this season, occurring one day after Dussehra celebrations. Forecasts from the India Meteorological Department and the Indian Institute of Tropical Meteorology predict that air quality will remain in the poor category over the coming days. The immediate triggers for the pollution spike included returning haze, low wind speeds, and colder conditions. Delhi recorded a minimum temperature of 18 degrees Celsius on Wednesday, which is below the seasonal average. Specific readings indicated that Palam registered 17.8 degrees Celsius, Lodhi Road 17.7 degrees Celsius, and Ridge 19.1 degrees Celsius. The India Meteorological Department forecast a maximum daytime temperature of approximately 31 degrees Celsius. According to data from the Central Pollution Control Board, the Air Quality Index stood at 233 at 9 a.m. Earlier in the day, the Sameer application showed an average index of 230 at 8:15 a.m. Forty-one of the 56 active monitoring stations recorded poor or worse air quality levels. The worst reading in Delhi was 318 at Pusa. In neighboring states, Ghaziabad recorded an index of 222, Greater Noida 248, Noida 203, and Gurugram 204. Faridabad remained in the moderate category with a reading of 124. Stage I measures activate when the Air Quality Index ranges between 201 and 300. The Commission for Air Quality Management ordered all implementing agencies in Delhi and NCR areas of Haryana, Uttar Pradesh, and Rajasthan to enforce these measures immediately. Key restrictions include a ban on the use of coal and firewood in tandoors at hotels, restaurants, and open eateries. Commercial kitchens must rely exclusively on electricity, gas, or other clean fuels. Diesel generators are restricted to essential or emergency use only. Open burning of garbage, leaves, and other waste is prohibited. Dust mitigation measures are mandatory at all construction and demolition sites, requiring projects larger than 500 square meters to possess an approved dust management plan. Enforcement actions extend to traffic and industrial sectors. Vehicles that visibly pollute the air are subject to fines or impoundment. Traffic police have been deployed at key intersections, and drivers are instructed to switch off engines at red lights to reduce idling. Diesel vehicles older than ten years and petrol vehicles older than fifteen years remain banned in Delhi. Polluting industries and thermal power plants within a 300-kilometer radius of Delhi face enforcement action. Residents are urged to adhere to the citizen charter, which advises turning off engines at red lights and preferring hybrid or electric vehicles. Firecracker production, sale, and storage are banned across the NCR until January 1, 2025. The sub-committee will monitor air quality and forecasts to determine if further action is required. These emergency curbs precede the launch of the Delhi government’s Winter Action Plan, effective November 1. The plan targets vehicular emissions, construction dust, and industrial pollution. A central component is the No PUC, No Fuel policy, which denies refueling to vehicles lacking a valid Pollution Under Control certificate. From November 1, 2026, until January 31, 2027, vehicles registered outside Delhi that do not meet Bharat Stage VI emission standards will be barred from entering the capital. Transport department estimates suggest more than one million vehicles in NCR areas of Gurugram, Faridabad, Noida, Greater Noida, and Ghaziabad could be affected. Gurugram and Faridabad alone hold nearly 200,000 non-compliant vehicles, roughly 70 percent of which are Bharat Stage III or IV models. Approximately 50,000 commercial vehicles in these two Haryana districts also fail to meet the standards. Noida and Greater Noida contain over 400,000 vehicles below Bharat Stage VI norms, with Bharat Stage IV petrol cars making up more than half of that total. Ghaziabad has around 400,000 non-compliant vehicles. To enforce the entry ban, authorities are deploying automatic number plate recognition cameras at border checkpoints and strategic lanes. Artificial intelligence-powered systems will assist in identifying incoming vehicles. Physical barriers are being fortified at entry points from Noida, Gurugram, and Ghaziabad. Approximately 300 personnel from transport department enforcement teams will be deployed to stop non-compliant vehicles. Electric and compressed natural gas vehicles are exempt from the entry restrictions. Medical experts emphasize that early intervention reduces exposure to particulate matter that affects lung and heart health. Particulate matter 2.5 can penetrate deep into the lungs, irritating airways and exacerbating asthma. Particulate matter 10 affects breathing and irritates the eyes, nose, and throat. Fine particles can also trigger inflammation and oxidative stress, straining blood vessels and contributing to cardiovascular disease. Physicians noted that individuals with hypertension, diabetes, or high cholesterol require particular caution during this period. Symptoms such as chest pressure, sudden breathlessness, or cold sweats warrant urgent medical attention. While Stage I measures aim to cut pollution at the source, they do not ban all vehicles or construction activity, nor do they guarantee an immediate drop in pollution levels. The effectiveness of the plan depends on consistent enforcement by agencies.

Delhi's air quality has deteriorated to the 'poor' category, with an average Air Quality Index (AQI) of 230 as of 8:15 AM. Forty-one out of 56 monitoring stations reported 'poor' or worse conditions, with Pusa recording the worst AQI at 318, the highest since mid-July. Neighboring areas like Ghaziabad, Greater Noida, and Gurugram also experienced high AQI values. Delhi's winter season typically exacerbates air pollution due to factors such as stubble burning in Punjab and Haryana, vehicle emissions, firecracker usage during Diwali, reduced wind speeds, and industrial activity. In response, Delhi Chief Minister Rekha Gupta announced measures starting November 1 under the Winter Action Plan, including restrictions on non-Delhi vehicles not meeting emission standards, enforcement of pollution control certificates for refueling, limitations on construction activities, and requiring 50% of office workers to work remotely.

As winter approaches, Delhi's air quality is worsening, with the Air Quality Index (AQI) expected to move into the 'Poor' category starting Wednesday and remain there for the next six days. According to forecasts from the Indian Institute of Tropical Meteorology (IITM), pollution levels have already risen, with PM2.5 being the main pollutant. Transport emissions are the leading cause of pollution, contributing 23.02% of Delhi's emissions, followed by residential sources at 6%. Stubble burning is also expected to contribute more significantly, rising from 4% to 12% by Wednesday. Satellite data from the Indian Agricultural Research Institute shows numerous instances of crop residue burning in several northern states, though none were detected in Haryana or Delhi on Monday. Cooler temperatures and reduced wind speeds are exacerbating the issue by limiting the dispersion of pollutants.
