Electric vehicles (EVs) offer significant health benefits in high-pollution regions by reducing harmful emissions linked to respiratory and cardiovascular diseases.
Key health benefits include:
- PM2.5 reductions: EVs produce no tailpipe emissions, eliminating direct particulate matter (PM2.5) linked to lung disease, asthma, and premature death. Even when accounting for grid-dependent emissions, studies show net PM2.5 reductions (e.g., 437 annual deaths avoided at 25% U.S. EV adoption).
- Lower ozone levels: Reduced NOx emissions from tailpipes correlate with decreased ground-level ozone formation, preventing respiratory issues (98 annual deaths avoided in the U.S. scenario).
- Region-specific improvements: Urban areas benefit most from reduced brake and tire particulates (due to regenerative braking) and localized tailpipe pollution.
Dependencies:
Health gains depend heavily on grid decarbonization. Combustion-heavy grids may offset benefits, while cleaner grids amplify them—75% EV adoption with low-emission energy avoids ~$70B in health damages annually in the U.S.
