However, a layer of smog continued to blanket Delhi, as the air quality index (AQI) was 389 at 7.15 a.m., falling into the 'very poor' category. However, some areas continued to have severe air pollution levels. According to the CPCB data, in 12 areas of Delhi, the AQI level remained between 400 and 500 whereas in 26 places, the level was above 300 and between 400.

Meanwhile, the Centre has announced staggered working hours for its employees. According to an order issued by the Union Ministry of Personnel, the employees have been advised to carpool and use public transport to minimise vehicular pollution. "Offices can operate from 9 a.m. to 5.30 p.m. or from 10 a.m. to 6.30 p.m.," the order stated.

Given the alarming air pollution, the Commission for Air Quality Management (CAQM) has amended the Graded Response Action Plan (GRAP), introducing stricter measures.

Under the revised guidelines, NCR states are mandated to suspend physical Classes up to Class 5 under GRAP Stage 3 and up to Class 12 under GRAP Stage 4.

The amended GRAP also includes a new directive under Stage 3, requiring state governments to implement staggered timings for public offices and municipal bodies to reduce traffic congestion and associated emissions. Under GRAP Stage 4, people have been advised to wear masks outdoors during periods of hazardous air quality.
