The implementation of GRAP-1 restrictions has commenced in Delhi, signalling the onset of the city’s seasonal pollution challenges. These measures are activated when the Air Quality Index (AQI) falls between 201 and 300, categorised as ‘Poor’. The Commission for Air Quality Management (CAQM) reported that the AQI reached 244 at 2 pm on 21 October 2026, indicating a significant deterioration from the previous day’s reading of 179, which was classified as ‘Moderate’.

According to the CAQM, the AQI is expected to remain in the ‘Poor’ category in the upcoming days, as forecasted by the Indian Meteorological Department and the Indian Institute of Tropical Meteorology. This marks the first time in several years that GRAP has been implemented so late in the season, raising concerns among local authorities and residents alike.

Government’s Action Plan to Combat Pollution

Delhi’s Environment Minister, Manjinder Singh Sirsa, highlighted the government’s commitment to addressing air pollution through both immediate and long-term strategies. He stated that public involvement has been essential in these efforts. The government has introduced an eleven-point action plan aimed at reducing pollution levels. This includes initiatives such as dust mitigation, the promotion of electric vehicles, and the identification of local pollution sources.

Among the measures outlined by Sirsa, vehicles lacking a valid Pollution Under Control (PUC) certificate will be denied fuel. Additionally, parking charges across Delhi will be doubled, with the exception of Metro parking facilities. To further mitigate vehicular emissions, staggered working hours and work-from-home arrangements will be implemented for government offices and the Municipal Corporation of Delhi.

Restrictions have also been placed on outdoor construction and demolition activities, with strict prohibitions on open burning. The government has deployed 608 anti-smog guns and 1,150 mist-spray units throughout the city to combat dust pollution. An Integrated Command and Control Centre (ICCC) has been established to monitor construction-related pollution, while an AI-based traffic management system is in operation to reduce vehicular emissions.

Comprehensive Measures Under GRAP Stage 1

The measures under GRAP Stage 1 encompass a range of actions aimed at improving air quality. These include regular mechanised road sweeping and water sprinkling, dust mitigation at construction sites, efficient waste management, and stringent checks on polluting vehicles. Enhanced traffic management and emission control measures are also being enforced in industries, power plants, and brick kilns.

The CAQM’s proactive approach aims to ensure that the air quality in Delhi is closely monitored and managed. The ongoing measures reflect a concerted effort by both the central and local governments to tackle the persistent issue of air pollution, which has plagued the city for years. The collaboration between various governmental bodies is crucial for the success of these initiatives.

As the city braces for worsening air quality, the effectiveness of these measures will be closely observed. The government’s commitment to tackling pollution is evident, and the implementation of GRAP-1 serves as a critical step in addressing the environmental challenges faced by Delhi.
