GRAP-3 Enforced in Delhi-NCR as Air Quality Turns ‘Severe’

The Central government has activated Stage III of the Graded Response Action Plan (GRAP) across Delhi-NCR after the region’s air quality plunged into the ‘severe’ category. The decision follows continuous Air Quality Index (AQI) readings near 400 in several parts of the national capital, including Anand Vihar, Chandni Chowk and Ashok Vihar, reflecting hazardous pollution levels.

Delhi’s Air Quality Worsens

According to the Central Pollution Control Board data on November 11, areas such as Bawana (AQI 412) and Jahangir Puri (AQI 394) reported severe air pollution, while nearby regions like Noida and Ghaziabad saw only marginal relief. Experts attributed the worsening conditions to stagnant wind flow, vehicular emissions and post-harvest stubble burning in neighbouring states.

Restrictions under Stage III

Under GRAP Stage III, non-essential construction activities across Delhi-NCR are banned to curb dust and particulate emissions. Classes up to grade V have been directed to switch to hybrid or online learning modes. BS-III petrol and BS-IV diesel vehicles are barred from plying within Delhi-NCR limits, except for essential services. Additionally, non-essential diesel medium goods vehicles of BS-IV or older standards are prohibited in the capital.

Implementation and Monitoring

The Commission for Air Quality Management (CAQM) has directed local authorities to strictly monitor industrial and transport-related emissions. Construction firms have been instructed to use anti-smog guns and dust suppression systems where exemptions apply. Officials have also warned that if pollution levels persist, Stage IV of GRAP — involving complete bans on truck entry and halting construction — may be invoked.

Exam Oriented Facts

• GRAP Stage III is triggered when AQI remains above 400, categorised as ‘severe’.
• Restrictions include a ban on non-essential construction and older vehicle categories.
• The plan is implemented by the Commission for Air Quality Management (CAQM).
• Delhi’s AQI on November 11, 2025, ranged from 365 to 412 across various monitoring stations.

Public Health and Advisory Measures

Authorities have advised residents, especially children and the elderly, to avoid outdoor activity and use N95 masks when outside. Schools and offices have been asked to promote work-from-home options, while citizens are urged to use public transport and avoid private vehicles. Environmentalists stress that long-term urban planning and renewable energy adoption are vital to prevent recurring winter smog crises in the capital region.
