Every Delhiite losing 8+ years of life to pollution – AQLI Report

Delhi residents stand to lose 8.2 years of their life expectancy due to persistently high concentrations of PM2.5 in the city’s air, according to the 2025 Air Quality Life Index (AQLI) report released by the Energy Policy Institute at the University of Chicago (EPIC). The loss could be reduced to 4.7 years if pollution levels are brought down to India’s national standard of 40 µg/m³, and almost eliminated if the city meets the World Health Organization (WHO) guideline of 5 µg/m³.

The study, based on 2023 satellite-derived PM2.5 data, revealed that Delhi recorded an annual concentration of 88.4 µg/m³—more than eight times the WHO limit. Nationally, India’s average was 41 µg/m³, with the average Indian losing 3.5 years of life expectancy. The global average loss stood at 1.9 years.

The report noted that particulate pollution in India rose in 2023 compared to 2022, worsening the health burden. “Consistent exposure at current levels could cut Delhi residents’ lives by eight years. Achieving the national standard would require halving current pollution levels and could add over 4.5 years to residents’ life expectancy,” said AQLI director Tanushree Ganguly.

Ganguly added that nearly 50% of Delhi’s pollution comes from local sources, which, if controlled, could help the city meet its targets.

The northern plains remain the worst-hit, with states like Bihar, Haryana, and Uttar Pradesh showing life expectancy losses of 5–5.4 years. Overall, 1.4 billion Indians—100% of the population—live in areas exceeding WHO limits, while nearly half live in regions breaching India’s national standards.

The report stressed that targeted reductions could yield immediate health benefits. Meeting WHO standards would give residents of India’s northern plains an average of five extra years of life, making pollution control a critical public health priority.

Delhi remains one of the top polluted cities in the world for the past many years. In an important development to alleviate air pollution in the national capital, the Delhi Government has flagged off electric buses for the students going to Sardar Patel Vidyalaya.
