Published by Ian Tiseo, Mar 11, 2025

The average person in India could live 3.6 years longer if national average fine particulate matter (PM2.5) levels were brought in line with World Health Organization (WHO) Air Quality guidelines of five µg/m3. This figure doubles in Delhi, where the average person stands to lose nearly 7.8 years of their lives based on 2022 PM2.5 concentrations. In 2023, the average annual PM2.5 concentration in Delhi was 102 µg/m3.
