The Commission for Air Quality Management (CAQM) has invoked Stage-III measures under the Graded Response Action Plan (GRAP) across the entire Delhi-National Capital Region (NCR), bringing stricter pollution-control restrictions into force with immediate effect from November 6, 2026.
The decision followed a review by the CAQM's GRAP Sub-Committee, which assessed Delhi-NCR's air-quality situation alongside weather forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM).
Editorial Insight
Key Highlights
Important points readers should notice.
Issue/Event: Deteriorating air quality in Delhi-NCR prompted the activation of GRAP Stage-III.
Location: India.
Authority/Organisation: Commission for Air Quality Management (CAQM), with NCR state authorities and pollution-control agencies.
Action Taken: Stage-III pollution-control measures invoked across Delhi-NCR with immediate effect from November 6, 2026.
- Impact: Stricter controls on construction activity and specified older vehicles, alongside existing pollution-control measures.
According to the official assessment, Delhi recorded a daily average Air Quality Index (AQI) of 382 on November 6, placing it in the 'Very Poor' category. Unfavourable meteorological conditions were limiting the dispersal of pollutants. Forecasts indicated that air quality could deteriorate further and enter the 'Severe' category.
The commission therefore activated Stage-III measures as a preventive response to the anticipated deterioration. The decision adds another layer of restrictions to the Stage-I and Stage-II measures that were already in force.
Construction and demolition activities face restrictions
Editorial Analysis
Why This Matters
Air pollution is a major public-health and environmental concern, particularly during the winter months when weather conditions can restrict the dispersal of pollutants. The escalation to Stage-III matters because it requires stronger interventions beyond routine pollution-control measures. Construction restrictions and vehicle-related curbs can affect residents, commuters, businesses, infrastructure projects and local industries. The regional approach also highlights the need for coordination between Delhi and neighbouring states. Pollution sources across administrative boundaries can influence air quality throughout the NCR. However, restrictions alone cannot guarantee an immediate improvement. Their effectiveness depends on enforcement, public cooperation, control of multiple emission sources and changing weather conditions.
One of the major measures under Stage-III is a ban on construction and demolition activities across the applicable Delhi-NCR areas.
The restrictions cover activities such as earthwork, excavation, trenching, road construction and major repairs. Certain essential infrastructure-related construction activities may be permitted under specified conditions in the applicable GRAP schedule.
The objective is to reduce dust emissions from construction sites and infrastructure work, which can contribute to particulate pollution across the region.
Restrictions on older vehicles
Stage-III also brings additional restrictions on the movement of certain older vehicles.
The measures include restrictions on BS-III petrol and BS-IV diesel light motor vehicles in Delhi, subject to the applicable GRAP provisions and exemptions. Residents and vehicle owners should check the latest official instructions before travelling, as restrictions depend on vehicle category, location and applicable exemptions.
Enforcement across Delhi-NCR
The CAQM has directed concerned agencies, including pollution-control boards and the Delhi Pollution Control Committee, to ensure effective implementation of the measures under all three active GRAP stages.
The commission's regional approach is important because air pollution is not confined to Delhi's administrative boundaries. Construction activity, road dust, industrial emissions, transport and other sources across neighbouring NCR districts can influence the region's air quality.
The authorities have also urged residents to reduce unnecessary travel, use cleaner transport options, avoid open burning and cooperate with pollution-control instructions.
Weather conditions remain an important factor
The November 6 assessment highlighted unfavourable meteorological conditions as a factor behind poor pollutant dispersion. When atmospheric conditions limit the movement of pollutants, emissions from different sources can accumulate near ground level.
The CAQM is monitoring air quality and weather forecasts to determine whether additional measures are required or whether restrictions can be relaxed as conditions improve.
The activation of Stage-III does not itself establish that pollution levels have already reached the 'Severe' category. The November 6 daily average was 382, while the forecast indicated a possible further deterioration.
The coming days will therefore be important for determining whether the restrictions help prevent further worsening of air quality across Delhi-NCR.
