Delhi’s Air Quality Crisis: AQI Hits 481, City Implements Emergency Measures

New Delhi has plunged into an environmental emergency, with its Air Quality Index (AQI) reaching a staggering 481, marking the season's worst levels and categorizing the air as "severe plus." The deteriorating conditions have triggered stringent anti-pollution measures, including the suspension of in-person classes for students up to Grade 9, while those in Grades 10 to 12 continue with precautions in place.

Adding to the chaos, dense fog blankets the city, reducing visibility and severely disrupting daily life, including flights and train services. Airlines like IndiGo and SpiceJet have issued travel advisories, urging passengers to check their flight statuses. Train delays have compounded frustrations, with several services, including long-distance trains like the New Delhi-Kochuveli Express, delayed by up to four hours.

Pollution and Weather

The India Meteorological Department (IMD) has issued an Orange Alert for Delhi, warning that thick fog is likely to persist. The fog, combined with high pollution levels, has created a hazardous environment, with pollutants trapped close to the ground due to low temperatures and stagnant winds. These conditions amplify health risks, especially for vulnerable groups like children and the elderly.

The situation has caught the attention of the Supreme Court, which will hear a plea to implement further measures against the pollution crisis. The case, presided over by Justices Abhay S Oka and Augustine George Masih, underscores the gravity of the situation, which threatens to cement Delhi's position as one of the world's most polluted cities.

Impact on Schools and Daily Life

To shield children from the harmful air, schools up to Grade 9 have shifted to online classes, while senior students continue in-person lessons under strict guidelines, including mandatory masks. In neighboring Sonipat, Haryana, schools for younger students have been completely closed to safeguard their health.

GRAP Stage IV: Emergency Measures

The National Capital Region (NCR) has activated Stage IV of the Graded Response Action Plan (GRAP), enforcing:

• Diesel Truck Ban: Only vehicles running on LNG, CNG, or BS-VI diesel, and those carrying essential goods, are allowed into Delhi.

• Construction Halt: All construction and demolition activities, including public infrastructure projects, have been stopped.

• Vehicle Restrictions: Medium and heavy vehicles using BS-IV or older diesel engines are banned unless transporting essential goods.

• Work-from-Home Mandate: Offices in the NCR are advised to operate at 50% capacity, with the remainder of employees working remotely.

The measures are part of a broader attempt to curb emissions from vehicular traffic and construction dust, major contributors to Delhi's toxic air.

Despite these efforts, stubble burning remains a significant culprit. Neighboring states like Punjab and Haryana have reported thousands of farm fires, with over 8,400 cases recorded this season. This practice continues to exacerbate Delhi's pollution crisis, even as authorities struggle to enforce bans and provide alternatives to farmers.
