New Delhi: The national capital has introduced stricter pollution control measures after a significant deterioration in air quality, with the central government implementing Stage III restrictions under the Graded Response Action Plan (GRAP) across Delhi and the surrounding National Capital Region (NCR).
The decision was announced on Friday following a review of the city's worsening pollution situation and a consistent rise in air pollution levels.
According to the Commission for Air Quality Management (CAQM), Delhi recorded an Air Quality Index (AQI) of 382 on November 6, 2026, placing it in the 'Very Poor' category. Officials attributed the situation to unfavourable weather conditions that prevented pollutants from dispersing effectively.
GRAP Stage III Implemented Across Delhi-NCR
The CAQM announced the immediate implementation of GRAP Stage III throughout the NCR, directing pollution control authorities and concerned agencies to ensure strict compliance with the prescribed measures.
The restrictions aim to reduce pollution levels by limiting activities that contribute significantly to deteriorating air quality.
One of the major measures under GRAP Stage III is a complete ban on non-essential construction and demolition work. The restrictions cover activities such as excavation, filling, boring, drilling, piling, brickwork, masonry, road construction and major repair work.
Restrictions on Older Petrol and Diesel Vehicles
The government has also imposed restrictions on certain older vehicles to control vehicular emissions.
Under the latest directions, BS-3 petrol and BS-4 diesel four-wheelers are prohibited from operating in Delhi and neighbouring NCR districts.
BS stands for Bharat Stage, the emission standards introduced by the Indian government to regulate the amount of pollutants released by motor vehicles.
These restrictions are intended to reduce emissions from older vehicles, which contribute to the region's air pollution.
Health Advisory Issued Amid Rising Pollution
With air quality remaining in the Very Poor category, health experts have advised residents to take precautions and minimise exposure to polluted outdoor air.
People have been urged to avoid outdoor activities during the early morning hours and after sunset. Residents should also refrain from prolonged or strenuous physical activities outdoors.
Individuals suffering from respiratory illnesses have been specifically advised to avoid outdoor physical exercise to minimise the risk of health complications.

Why Does Delhi Face Severe Air Pollution Every Winter?
Delhi is frequently counted among the world's most polluted cities, particularly during the winter months. Several factors contribute to the city's deteriorating air quality, including industrial emissions, increasing vehicular traffic and extensive construction activities.
Weather conditions during the winter season can further aggravate the problem by limiting the movement and dispersion of pollutants in the atmosphere.
Over the years, air pollution has become a recurring concern for residents of Delhi and the surrounding NCR region, with air quality often reaching hazardous levels as winter approaches.
The implementation of GRAP Stage III is part of the government's efforts to control pollution sources and prevent further deterioration in the capital's air quality.
