Delhi’s Air Quality Hits Hazardous Levels, Emergency Measures Activated
Delhi’s air quality has plunged to alarming levels, with the daily average Air Quality Index (AQI) reaching a staggering 431 at 4 PM today, as reported by the Central Pollution Control Board (CPCB). The situation continued to deteriorate, with the AQI climbing to 441 by 6 PM. In response to these critical levels, an emergency meeting was convened by the Sub-Committee of the Graded Response Action Plan (GRAP) to address the escalating air pollution crisis in the National Capital Region (NCR).
During the emergency session, the Sub-Committee evaluated the current air quality trends and meteorological forecasts provided by the Indian Meteorological Department (IMD) and Indian Institute of Tropical Meteorology (IITM). The meeting highlighted that the ongoing increase in AQI is largely attributed to unfavorable weather conditions rather than vehicular emissions. A weak Western Disturbance is causing reduced wind speeds and a shift in wind direction, which has led to heightened moisture levels in the atmosphere. These factors contribute to the formation of smog, resulting in a significant build-up of pollutants near the ground.
To combat the rapid decline in air quality, the Sub-Committee has enacted measures corresponding to Stage-IV of the GRAP, designed for ‘Severe+’ air quality conditions when AQI exceeds 450. The measures will be enforced immediately across the NCR, supplementing existing restrictions outlined under Stages I, II, and III of the GRAP. Various agencies responsible for pollution control are urged to ensure rigorous implementation of these new actions.
5-Point Action Plan Under Stage-IV
Following the declaration, a five-point action plan has been introduced, effective immediately throughout the NCR. The key components of this action plan include:
- Prohibiting the entry of BS-IV trucks into Delhi, except those carrying essential goods or services. Entry of LNG, CNG, electric, and BS-VI diesel trucks will still be allowed.
- Imposing a strict ban on operation of Delhi-registered diesel-operated heavy goods vehicles (HGVs) classified as BS-IV or below, unless they are delivering essential commodities or services.
- Extending the ban on construction and demolition activities, including those related to linear projects like highways and telecommunications.
- Mandating hybrid classes for students in higher classes (VI to IX and XI) in schools located in the NCT of Delhi and the neighboring districts (Gurugram, Faridabad, Ghaziabad, and Gautam Buddha Nagar).
- Encouraging state governments to consider additional measures, such as closing colleges or non-essential businesses and implementing odd-even traffic systems.
In light of these new restrictions, the Commission for Air Quality Management (CAQM) urges residents of the NCR to adhere to the citizen charter established under GRAP. They recommend that vulnerable groups, including children and those with pre-existing health conditions, limit outdoor activities. If necessary, individuals are advised to wear masks when outside.
The full schedule of the GRAP is available for public access on the Commission’s official website.
