Delhi's Air Quality Crisis: A Year-Round Struggle Amidst Diwali Celebrations

Strategic Insights -

Millions of people in India's capital woke up to the most polluted air in the world on Wednesday, a day after Diwali celebrations, which typically involve setting off fireworks and firecrackers. New Delhi's PM 2.5 concentration was more than 40 times the World Health Organization's annualized guideline level, according to IQAir. The city's severe air pollution persists year-round, with the winter months being the worst. The deterioration in air quality this week comes following Diwali celebrations, despite a ban on firecrackers in 2020 and a curfew on "green" firecrackers this year.
