Singapore High Commission Advises Nationals on Delhi’s Stage 4 Pollution Alert and Potential Flight Disruptions

Breaking: Delhi-NCR Under GRAP Stage 4 As Pollution Curbs Tighten And Travel Alerts Go Up

The Central Pollution Control Board has activated Stage 4 of the Graded Response Action Plan across the Delhi National Capital Region, imposing the highest level of pollution controls. The move, effective from December 13, 2025, restricts construction and non‑essential industrial activity across the region, while officials urge schools and offices to consider hybrid or remote work where possible.

In a related development, the Singapore High Commission in New Delhi issued an advisory to Singapore nationals in the Delhi NCR, urging adherence to local restrictions and cautioning travellers about possible travel disruptions as visibility drops.

Travel disruption is anticipated as low visibility can affect flight operations at Indira Gandhi International Airport. Airlines have issued advisories, and travelers are advised to verify schedules with their carriers before heading to the airport.

What Stage 4 means is straightforward: authorities restrict non‑essential activities, and residents are urged to stay indoors, notably children and people with respiratory or cardiac conditions.Masks are recommended for outdoor exposure until air quality improves.

With wintertime pollution spikes common in northern India, authorities typically escalate measures to curb activity and safeguard public health. Citizens should monitor official updates, limit outdoor exertion, and plan for possible travel delays by allowing extra time and keeping critically important documents ready.
