As winter approaches, the Commission for Air Quality Management (CAQM) has introduced revised Graded Response Action Plan (GRAP) guidelines aimed at addressing the worsening air quality in Delhi and the National Capital Region (NCR). These new measures reflect an urgent response to the persistent pollution challenges faced by one of the world’s most polluted urban areas, particularly during the winter months when air quality tends to deteriorate significantly.
The updated GRAP guidelines, issued under Section 12 of the Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021, focus on implementing stricter and more predictive measures based on daily Air Quality Index (AQI) forecasts. This proactive approach aims to mitigate the health risks associated with poor air quality, particularly for vulnerable populations, including children and the elderly. Key measures within the revised guidelines include an increase in parking fees to discourage vehicular use, thereby aiming to alleviate road congestion and reduce emissions. This initiative aligns with the broader objective of promoting sustainable urban transport solutions in a region plagued by traffic-related pollution.
Since its inception in January 2017, the GRAP has evolved through several revisions, reflecting the growing understanding of air pollution dynamics. The guidelines have become essential tools for managing air quality in Delhi-NCR, a region often synonymous with smog and air quality alerts. Notably, officials from the Uttar Pradesh Pollution Control Board have acknowledged the necessity for ongoing adaptations to the plan, given the complex environmental challenges faced. Among the new enforcement measures scheduled to take effect when the AQI exceeds 400—placing it in Stage III of GRAP—are the prohibition of inter-state buses, excluding electric and CNG vehicles, from entering Delhi. Additionally, there will be a complete ban on construction and demolition activities, a suspension of mining-related operations, and the possibility of shifting to online classes for students up to Class V. Furthermore, daily water sprinkling on major roads is mandated to mitigate dust pollution.
These measures come at a critical time, as public health experts warn that prolonged exposure to poor air quality can lead to serious health issues, including respiratory diseases and cardiovascular problems. By implementing these stringent guidelines, the CAQM is not only prioritising the health of residents but also underscoring the importance of sustainable practices in urban management. As the winter months loom, the collective efforts of regulatory bodies, local governments, and citizens will be crucial in navigating the air quality crisis and fostering a cleaner, healthier environment for all
