While there is no direct analysis of EV adoption’s health impacts across varying urban pollution levels in the provided sources, the relationship can be inferred through existing data on pollution-related health risks:
In Heavily Polluted Cities
- Magnified benefits: Transitioning to EVs in cities with high PM₂.₅ levels (e.g., densely populated urban centers) could reduce emissions from combustion engines, directly lowering respiratory/cardiovascular risks linked to traffic-related pollutants like nitrogen oxides and ultrafine particles.
- Targeted impact: WHO estimates 4.2 million annual premature deaths from ambient air pollution globally, primarily in urban areas. EV adoption here could disproportionately reduce strokes, lung cancers, and COPD.
In Moderately Polluted Cities
- Partial mitigation: EVs reduce localized emissions (e.g., near roads/schools), addressing “hotspot” exposure risks, even if background pollution persists from non-transport sources (industry, heating).
- Synergistic gains: Combined with stricter industrial regulations, EV adoption contributes to incremental air quality improvements, lowering risks for conditions like aggravated asthma and diabetes.
Health Outcome Comparisons
| Pollution Level | Key Health Risks | EV Impact Potential |
|---|---|---|
| High | Stroke, lung cancer, COPD | Most significant due to high baseline disease burden |
| Moderate | Asthma, diabetes, dementia | Moderate (supports wider air quality policies) |
Current evidence suggests the greatest health benefits per EV deployed would occur in cities with the worst air quality, particularly where transport emissions dominate pollution sources. However, systemic pollution sources (e.g., coal plants) may dilute EV-related improvements without complementary policies.
