Delhi has witnessed a respite from its toxic air as continuous rainfall has significantly improved air quality in the national capital and surrounding areas. On Friday, the Commission for Air Quality Management (CAQM) announced the lifting of stringent pollution curbs under Stage 3 of the Graded Response Action Plan (GRAP), with immediate effect. However, restrictions under Stage 2 of GRAP remain in force across Delhi-NCR to prevent a relapse into deteriorating air quality.
The 24-hour average air quality index (AQI) in Delhi stood at 324 at 7 pm on Friday, showing a declining trend that reflects improving conditions. Forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM) predict further improvement in air quality due to favorable weather conditions.
Stage 2 of GRAP includes several measures aimed at mitigating air pollution in the region. These include mechanized sweeping of roads, daily water sprinkling to control dust, and focused efforts at identified air pollution hotspots. Anti-smog guns are also being deployed to curb particulate matter in the air. Power suppliers have been directed to ensure an uninterrupted electricity supply to minimize the reliance on diesel generator sets.
Public awareness campaigns will continue, with alerts issued through newspapers, television, and radio to inform people about pollution levels. Residents are encouraged to use public transport instead of personal vehicles and to opt for less congested routes, even if they are slightly longer. Vehicle owners are also advised to regularly replace air filters to ensure their automobiles contribute minimally to pollution levels.
Certain restrictions will remain in place under GRAP Stage 2. The use of coal and firewood is still banned across Delhi-NCR, which includes the prohibition of tandoors in restaurants and hotels. Diesel generator sets can only be used for emergency and essential services. Construction and demolition activities at sites under specific closure orders, as well as operations in certain industrial units, remain prohibited.
These measures aim to prevent air quality from slipping back into the ‘very poor’ or ‘severe’ category. With continuous efforts by the authorities and cooperation from residents, Delhi-NCR is striving to maintain and further improve its air quality. While the current easing of restrictions brings relief, the region remains vigilant to ensure sustainable air quality levels in the coming days.
