Air pollution costs are staggering—€330 billion/year in Europe, ~US$1 trillion in the U.S., and US$141 billion in MENA (≈2% of regional GDP) through premature deaths, illness, and lost productivity.

MegaSense’s calibrated frontier city solution transforms air quality management by publishing hourly pollution maps at 50 m resolution. With 90% of city streets mapped in near real time, residents can avoid hotspots, reducing exposure to NO₂ and PM₂.₅ by 30–50%. Authorities can target the top 5–10% of streets driving emissions, while open data empowers communities to demand cleaner air. This shifts cities from reactive to data-driven, improving public health and urban livability.​
