Pre-Diwali Pollution Woes in Delhi Reach New Highs

As Delhi approaches Diwali, air quality levels have alarmingly sunk into the ‘very poor’ category, with the Defence Colony area recording an Air Quality Index (AQI) of 324 early Monday morning. The city registered a marginal improvement in AQI to 264, a decrease from the prior day’s 355, but conditions remain concerningly unhealthy, underscoring the ongoing struggle to control pollution. Despite these efforts, Delhi’s air quality faces a predictable decline as winter and festive activities exacerbate existing environmental challenges. In areas like Pitampura, the AQI showed lower levels, standing at 167, though several hotspots across the city continue to register critical readings.

The drop in AQI over recent days aligns with a seasonal trend where calm winds prevent the dispersal of pollutants, intensifying pollution across urban areas. Sunday saw a high of 355 on the AQI, and three monitoring stations—Bawana, Burari, and Jahangirpuri—reported ‘severe’ air quality conditions, highlighting that several regions within the National Capital Region (NCR) continue to face alarming pollution levels. In response, the Delhi government has reinforced a series of anti-pollution measures under the Centre’s Graded Response Action Plan (GRAP), which reached Stage 2 on 21 October. GRAP’s mandate is intended to counter the seasonal spike in pollutants and includes enhanced public transportation options, dust suppression drives, and a comprehensive ban on firecrackers, designed to alleviate pollution during the winter season.

Sustainability measures are also underway, but several issues complicate enforcement. Delhi’s longstanding ban on traditional firecrackers persists, allowing only ‘green’ crackers that meet strict environmental standards. However, inadequate distinction between green and traditional firecrackers has led to continued restrictions. Meanwhile, the Delhi Pollution Control Committee (DPCC) has extended its ban on manufacturing, selling, and bursting of firecrackers until January 2025. Despite these policies, a report from Gurugram reveals cross-border movement of traditional firecrackers into Delhi, posing further pollution risks and challenging the efficacy of existing enforcement mechanisms.

As civic authorities and residents grapple with the persistent air quality dilemma, sustainability remains a priority, though the task is substantial. Experts highlight that addressing pollution requires a multipronged strategy, balancing policy enforcement with enhanced urban planning and resident awareness. The measures taken by the Delhi government, though critical, are under close scrutiny as public health remains vulnerable in the absence of impactful, sustainable changes. With air quality predicted to worsen through Diwali, residents and policymakers alike face the challenge of navigating this period without further compromising public health and environmental integrity.
