Understanding the air we breathe, the climate we shape.
We investigate how human activities and natural processes shape the chemical composition of the atmosphere at the molecular level and its consequences for air quality and climate.

AIR POLLUTION & HEALTH
The human cost of polluted air
Estimated deaths attributable to air pollution, projected from IHME’s annual burden estimates.

Data source & calculation
Source: IHME, Global Burden of Disease 2023, as reported in State of Global Air 2025 (HEI / IHME). Reference-year estimates: approximately 2 million deaths in India and 7.9 million worldwide in 2023. The report describes India’s total as more than 2 million; this display uses a rounded 2 million baseline. Includes the combined burden from ambient particulate matter, household air pollution and ozone.
Daily average = rounded annual estimate ÷ 365. The year-to-date projection multiplies this average by completed calendar days since 1 January in India Standard Time. Values are rounded to the nearest ten. This assumes a constant daily burden and does not represent seasonal variation, current-year observations or uncertainty intervals. Only the projection updates daily; source estimates require revision when a new dataset is adopted.

OUR APPROACH
From emissions to impacts
Why air chemistry matters?
The atmosphere is a complex reactor in which hundreds of thousands of precursors transform via different oxidation processes. Gases form airborne particles - particles can form clouds, deposit in our lungs or impact the broader ecosystem. We combine field measurements, laboratory experiments and advanced data wrangling and analysis methods to trace reactive organic emissions from their sources through chemical transformation to effects on air quality.
