Delhi Tops List of Most Polluted Megacities: Residents Face Potential Loss of 11.9 Years Due to Air Pollution
A recent global report released on Tuesday highlights the severe impact of air pollution in Delhi, naming it as the world’s most polluted megacity. According to the report by the University of Chicago’s Energy Policy Institute (EPIC), individuals residing in Delhi are at risk of losing nearly 12 years of their lives due to air pollution, marking the highest life expectancy reduction among all megacities. The satellite cities of Noida and Gurugram also rank high, with an average potential loss of life exceeding 11 years.
The Air Quality Life Index 2023 report utilized data from 245 countries and territories, analyzing annual average levels of PM2.5, a fine particulate matter known to cause severe health problems and premature mortality. The study compared these levels to the World Health Organization’s (WHO) standard of 5 micrograms per cubic metre (µg/m3) for PM2.5, using 2021 as the base year.
The EPIC report revealed that the national capital region (NCR) stood as the most polluted hotspot in India, causing its inhabitants to experience the most significant global impact. In last year’s report, which used 2020 as the base year and incorporated revised WHO standards, Delhi residents faced a loss of 10.1 years of life due to severe air pollution.
Following Delhi, Gautam Budh Nagar (encompassing Noida and Greater Noida) residents could potentially lose 11.3 years, while Gurugram, Faridabad, and Ghaziabad residents might lose 11.2, 10.8, and 10.7 years, respectively. The findings underscore the urgent need for comprehensive efforts to address air pollution throughout the entire metropolitan area.
