Global pollution is dropping — and EVs are a big reason why

A major study from USC’s Keck School of Medicine shows that communities adopting electric scooters and cars are seeing real improvements in air quality. By analyzing data from 2019–2023, researchers found that higher EV adoption directly lowers nitrogen dioxide (NO₂)—one of the most harmful traffic pollutants linked to asthma, heart disease, bronchitis, and strokes.

📉 Key insight:
For every 200 additional EVs in a neighborhood, NO₂ levels drop by ~1.1%. That may sound small, but across cities and countries, it means massive health benefits for millions.

This is strong real-world evidence that EVs don’t just reduce carbon emissions—they clean the air people actually breathe where they live, work, and raise families.
