Somewhere in India today, a grandparent is wheezing through a morning walk and a child is staying home with a cough that won’t clear. Multiply that by a country of 1.4 billion people and you get the statistics making headlines this week. They are not new measurements, though. The “fresh data” comes from a report published on October 9 that pulls together earlier studies, and the death counts are for 2022 and 2023. Here are the numbers that matter.
2 million+ deaths in 2023
India and China each had more than 2 million deaths attributable to air pollution in 2023, according to the State of Global Air 2025 report. The report is a collaboration between the Health Effects Institute and the Institute for Health Metrics and Evaluation. It counts outdoor particles, household smoke and ozone together.
1.72 million deaths from human-made fine particles
The Lancet Countdown counts only the fine particles people put into the air. It found over 1,718,000 deaths from this source in India in 2022, up 38% since 2010. The two figures differ because they measure different things, not because they disagree.
48.9 µg/m³ average PM2.5 in 2025
PM2.5 means particles under 2.5 micrometres wide, small enough to reach the bloodstream. India’s 2025 average was nearly 9.8 times the WHO annual guideline of 5 µg/m³, placing it sixth globally in IQAir’s report. India’s own national standard is 40 µg/m³.
44% of those deaths tied to fossil fuels
Fossil fuels contributed to 752,000 of the 2022 deaths, and coal accounted for 394,000, mostly from power plants (298,000). Petrol used in road transport accounted for another 269,000. Burning wood, dung and crop waste make up much of the rest.
US$339.4 billion, or 9.5% of GDP
The Lancet Countdown put the monetised value of premature deaths from outdoor air pollution in 2022 at that figure. It is a valuation of lives lost, not a bill the government paid.
Taken together, the figures describe a country where the entire population lives above the WHO guideline, and where coal and traffic account for hundreds of thousands of deaths a year. Environmentalist Shailender Kumar told ETV Bharat the problem is structural and year-round. The newest death count covers 2023, and no national estimate yet shows whether the 2025 dip in average PM2.5 has changed it. IQAir says that dip is not statistically significant.
