The “severe” air pollution level in Delhi has triggered the implementation of GRAP Stage 4 anti-pollution measures in Delhi-NCR. The air quality in Delhi worsened further, recording an Air Quality Index (AQI) of 481 by 6 am on Monday morning, placing it in the “severe plus” category.

 Diesel-run medium and heavy goods vehicles registered in Delhi (BS-IV or below) are banned, except those carrying essential goods.

Non-essential light commercial vehicles from outside Delhi are prohibited unless they use cleaner fuels like CNG, BS-VI diesel, or are electric vehicles.

Trucks carrying non-essential items are barred from entering Delhi unless they operate on LNG, CNG, or BS-VI diesel.

 Schools and workplaces face adjustments as well. The CAQM panel recommended shifting classes 6 to 9 and class 11 to online mode.

Offices in NCR are advised to operate at 50 per cent capacity, with the remaining workforce working from home.
