The Delhi government has announced a series of permanent anti pollution measures that will be enforced every winter in an effort to tackle the city’s severe air pollution crisis. Unlike previous years, when restrictions were introduced only after pollution reached dangerous levels, the new rules will automatically come into effect each winter regardless of daily air quality readings.
The measures will be implemented every year from November 1 to February 28, covering the period when Delhi experiences its worst air pollution. Government data from the past three years shows that between November 1 and February 15, the city’s average Air Quality Index (AQI) has ranged between 312 and 342, a level classified as “very poor” to “severe.” By comparison, an AQI between 0 and 50 is considered healthy.
Until now, authorities activated pollution-control measures under the Graded Response Action Plan (GRAP) only after air quality crossed specific thresholds. The new policy marks a major shift by introducing preventive restrictions before pollution reaches critical levels.
Under the winter action plan, parking charges across the city will be doubled to discourage the use of private vehicles and encourage public transport. Government offices will operate with staggered working hours to reduce traffic congestion during peak times.
The government has also announced a ban on all outdoor civil construction activities during the winter season, except for essential public infrastructure projects. Construction dust is one of the major contributors to particulate pollution in Delhi, especially during the colder months when weather conditions trap pollutants close to the ground.
Another significant measure requires both government and private offices to adopt a hybrid work model between November 1 and January 31. Only half of the workforce will be allowed to work from offices at any given time, while the remaining employees will work from home. Officials believe this will help reduce daily traffic volumes and vehicle emissions across the capital.
The government has warned that strict action will be taken against those who fail to comply with the new regulations. Violators may face penalties, including prosecution, under applicable environmental laws.
The announcement is part of a broader strategy to reduce pollution from transport, one of Delhi largest sources of emissions. Earlier this week, the Delhi government unveiled a new electric vehicle incentive programme offering more than 1,000 US dollars to owners who scrap old vehicles and replace them with electric vehicles. The scheme aims to accelerate the shift towards cleaner transportation while reducing emissions from ageing petrol and diesel vehicles.
Delhi has consistently ranked among the world’s most polluted cities during winter. A combination of vehicle emissions, industrial pollution, construction dust, biomass burning, and crop residue burning in neighbouring states, together with stagnant weather conditions, often causes thick smog to blanket the capital for weeks.
By making winter pollution controls mandatory every year instead of waiting for pollution levels to worsen, the Delhi government hopes to reduce the intensity of seasonal smog and improve public health. The new approach reflects a shift from emergency response to preventive air quality management, with authorities aiming to limit pollution before it reaches hazardous levels.
