Electric vehicles (EVs) offer substantial health benefits in densely populated cities, primarily through improved air quality and reduced exposure to harmful pollutants. Here’s a breakdown of key findings:
1. Reduced Premature Deaths
EV adoption significantly lowers mortality rates linked to air pollution. A 2024 University of Houston study projected that full electrification of light-duty vehicles could prevent:
- 157 monthly deaths in Houston
- 796 monthly deaths in New York City
- 328 monthly deaths in Chicago
These reductions stem from fewer respiratory and cardiovascular diseases caused by pollutants like PM2.5 and ozone.
2. Decreased Respiratory Illnesses
- 6,300 annual U.S. deaths could be avoided by 2050 through nationwide EV adoption, along with 93,000 fewer asthma attacks, according to the American Lung Association.
- Brake dust pollution (linked to respiratory issues) is lower in EVs due to regenerative braking systems.
3. Climate and Air Quality Synergies
- CO₂ reduction: A 25% EV adoption in the U.S. could cut 242 million tons of CO₂ annually, rising to peak benefits at 75% adoption with cleaner energy grids.
- Ozone mitigation: Lower tailpipe emissions reduce ground-level ozone formation, particularly in high-traffic urban areas.
4. Nuanced Outcomes
While most cities see net benefits, Los Angeles faces complexities:
- 29% EV adoption prevents 104 monthly deaths
- Full electrification could increase mortality if local PM2.5/ozone rises due to grid emissions.
This highlights the critical role of clean energy grids in maximizing health gains.
Economic Benefits
Health improvements translate to cost savings exceeding $51M–$249M daily in major cities through reduced healthcare burdens and lost workdays. Urban communities of color and low-income areas—often disproportionately exposed to pollution—stand to benefit most.
