Delhi-NCR Enters Pollution Alert As GRAP Stage I Comes Into Force
Preventive measures triggered as pollution levels worsen across NCR
The Commission for Air Quality Management (CAQM) on Thursday invoked Stage I of the Graded Response Action Plan (GRAP) across Delhi-NCR after air quality in the national capital deteriorated to the “poor” category. The decision was taken during a meeting of the sub-committee on GRAP held on April 16, as authorities observed a consistent upward trend in pollution levels driven by unfavourable environmental conditions.
According to official data, Delhi’s Air Quality Index (AQI) was recorded at 226, placing it firmly within the ‘Poor’ category. Authorities attributed the worsening air quality to adverse meteorological conditions that have restricted the dispersion of pollutants, leading to their accumulation in the atmosphere. Forecasts issued by agencies such as the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM) indicate that air quality is expected to remain in the ‘Poor’ category over the next two days, prompting the need for immediate preventive action.
With the activation of Stage I under GRAP, a range of precautionary measures will now be implemented across the National Capital Region to prevent further deterioration in air quality. These measures typically include stricter enforcement of dust control at construction and demolition sites, regulation of vehicular emissions, improved road cleaning, and intensified monitoring of pollution sources. Authorities are also expected to step up public awareness efforts and ensure compliance with environmental norms among industries and the general public.

The move once again highlights the persistent challenge of air pollution in Delhi-NCR, particularly during periods of adverse weather that exacerbate pollution levels. Officials have emphasised the importance of coordinated efforts among multiple agencies, along with active public participation, to manage and reduce pollution effectively. Continued monitoring and timely intervention remain critical to prevent escalation into more severe categories, which would trigger stricter restrictions under the GRAP framework.
