As Tuesday dawned citizens of this heavily contaminated metropolis encountered inhaling extremely polluted air that fell into the "severe" range.

Extremely High Air Quality Measurements

Several parts of Delhi registered an AQI above 500, which represents 10x the recommended level recommended by the WHO.

In some locations, readings of PM2.5 and PM10 soared to of 1,800, amounting to fifteen to twenty times above acceptable standards.

Firecracker Restrictions and Current Policy Shifts

Since 2020, authorities had maintained a comprehensive restriction on the purchase and ignition of pyrotechnics during Diwali due to their major role to the deadly pollution that blankets the metropolis as winter sets in.

Yet in recent months, the current city administration appealed to the highest court to propose a easing of the restrictions.

The suggestion was allowing "eco-friendly fireworks" – previously criticized by environmental experts as being only approximately one-third reduced emissions – as a middle ground between "tradition and ecological concerns".

Court Ruling and Implementation

Despite concerns of public health and environmental activists, judicial authorities approved the proposal, mandating that green firecrackers could be set off during specific time windows throughout the celebrations.

Throughout the festival evening, there was widespread violation of the time restrictions across the metropolis, with minimal enforcement regarding whether the fireworks being used were actually the more environmentally friendly type.

Numerous air quality sensors throughout Delhi recorded air quality reaching highest levels around late evening to the most severe readings observed during the festival in at least recent memory.

International Consequences

Extensive ignition of firecrackers during the celebrations also sparked a dispute with adjacent the neighboring country, with authorities in Pakistan's the Punjab region partially attributing declining pollution levels in their urban centers on pollutants traveling from neighboring India following the celebrations.

Persistent Environmental Problem

Alarmingly severe levels of pollution in the city have remained as a major issue for more than 15 years, with the condition showing no improvement.

Around celebratory seasons, the levels of hazardous particulate matter in the atmosphere has been documented to spike to 70% higher the peak levels ever documented in the Chinese city, which was formerly considered as the world's most polluted urban center.

Multiple Pollution Factors

The situation in Delhi is resulting from a combination of various sources including heavy vehicle emissions, airborne particles, development work, garbage fires and smoke from crop residue ignition in adjacent areas of Punjab and Haryana.

In these regions, rural residents illegally ignite agricultural waste to clear them quickly, producing toxic haze that remains stagnant over the capital as cooler air sets in.

Health and Financial Consequences

The economic and health consequences on the roughly thirty-three million residents living in the capital region is significant, according to various studies.

The contaminated air leads to high levels of neurological, heart and circulatory and respiratory conditions, and can even lead to malignancies.

The pollution is calculated to be accounting for approximately 10k untimely deaths per year in Delhi.
