India Reality Check · Air
What does polluted air take from our lives? On average, 3.5 years.
The Air Quality Life Index turns particle pollution into years of life. The number for India is large, and it is not spread evenly.
This is an editorial draft. It has not yet been reviewed. Check its figures against the linked sources before relying on it.
What is the problem?
Fine particles (PM2.5) are small enough to reach deep into the lungs and the blood. Living with them every day for years has a cost that does not show up in any single day's air quality number.
What does the evidence show?
The Air Quality Life Index (AQLI) 2025 report, from the University of Chicago's Energy Policy Institute, says the average person in India loses about 3.5 years of life expectancy to particle pollution, compared with about 1.9 years worldwide. It puts India's average PM2.5 at about 41 µg/m³ in 2023. The WHO guideline is 5 µg/m³ a year and India's national standard is 40 µg/m³. By the report, every part of India is above the WHO guideline, and nearly half of Indians live in areas above the national standard.
Why does it matter?
Years of life are a way to feel a number that is otherwise abstract. They also show that clean air is a health issue for everyone, not only on the worst days.
What causes it?
Particle pollution has many sources, including vehicles, industry, dust, burning of crop residue and waste, and weather that traps smog in winter. The mix differs by city and by season.
What can be done?
Check your own city's air on this site, then ask your local authorities what they are doing about the main sources in your city. Reducing your own exposure helps a little, but the lasting fix is cleaner air for everyone.
