Delhi's Air Quality Crisis: Diwali Fireworks Ignite Alarming Pollution Spike

New Delhi's air quality hit hazardous levels due to Diwali fireworks, becoming the world's most polluted city. The Supreme Court's relaxation allowed limited 'green crackers,' yet breaches occurred. The city's pollution was exacerbated by weather and emissions, affecting millions. Lahore shares similar pollution challenges, partly from cross-border smog.

New Delhi faced severe air pollution on Tuesday as the city's air quality index hit hazardous levels, making it the most polluted major city globally according to IQAir data. The spike in pollution was partly attributed to firecracker emissions from Diwali celebrations.

Last week, India's Supreme Court eased restrictions on firecracker usage for Diwali, allowing so-called 'green crackers' despite observed violations in their use. These firecrackers have reduced emissions compared to traditional ones but still contributed significantly to the pollution.

As the city's smog intensified, pollution control authorities documented PM 2.5 levels far exceeding World Health Organization recommendations. The pollution crisis extends beyond India, with Pakistan's Lahore experiencing similar smog challenges exacerbated by air from India.
