Delhi is once again grappling with a severe air pollution crisis, prompting authorities to impose emergency measures to protect public health. As air quality levels remained in the “severe” category for consecutive days, the capital and its surrounding regions were placed under the highest level of the Graded Response Action Plan. The move reflects growing concern over the health risks posed by prolonged exposure to toxic air, particularly for children, the elderly, and those with respiratory illnesses.
Winter conditions in north India often worsen pollution levels, as low temperatures and weak winds prevent the dispersion of pollutants. This year, the situation escalated rapidly, forcing authorities to intervene with strict and immediate controls.
Vehicle Restrictions to Cut Emissions
Vehicular emissions are among the largest contributors to Delhi’s pollution, especially during winter. To tackle this, authorities have tightened rules on the use of private and commercial vehicles. Only vehicles meeting the latest emission standards are permitted to operate without restriction, while older and more polluting vehicles face strict checks.
Fuel stations have been instructed not to supply fuel to vehicles lacking valid pollution certificates, and enforcement teams have increased monitoring across the city and at border entry points. Heavy diesel trucks that do not meet current emission norms have also been barred from entering Delhi, except when carrying essential goods. Officials believe these steps will significantly reduce particulate matter and nitrogen oxide levels.
Work-From-Home Push to Reduce Traffic
In an effort to lower the number of vehicles on the roads, the government has ordered offices to function with reduced on-site attendance. Both public and private sector offices are required to operate at half capacity, with the remaining workforce encouraged to work from home.
By limiting daily commuting, authorities aim to ease traffic congestion during peak hours and curb emissions linked to office travel. Essential services, including healthcare, emergency response, electricity, water supply, and public transport, have been exempted from these restrictions to ensure continuity of critical operations.
Construction Activities Put on Hold
Construction and demolition work, a major source of dust pollution, has been temporarily suspended across the capital. The ban applies to both public infrastructure projects and private developments. While the measure is expected to bring down dust levels in the air, it also affects thousands of construction workers.
To offset the economic impact, the government has announced financial support for registered construction workers whose livelihoods are disrupted during the suspension period. Authorities have said the ban will remain in place until air quality shows sustained improvement.
Why Delhi’s Air Worsens Every Winter
Delhi’s pollution problem intensifies each winter due to a combination of human activity and meteorological conditions. Emissions from vehicles, industries, construction sites, and power generation accumulate in the atmosphere when cold air traps pollutants near the surface. Crop residue burning in neighbouring states further adds to the pollution load, worsening the situation across the region.
Health experts warn that exposure to such high pollution levels can cause breathing difficulties, aggravate asthma, and increase the risk of heart and lung diseases. Residents have been advised to limit outdoor activity as long as air quality remains poor. Officials have indicated that emergency measures will continue until pollution levels improve, and additional restrictions may be introduced if required. While these short-term actions may provide some relief, experts stress that Delhi’s recurring air quality emergencies underline the need for long-term solutions, including cleaner transport systems, better waste and dust management, and stronger regional coordination. Until such measures are firmly in place, Delhi’s battle against winter smog is likely to remain an annual challenge.
