Air Quality and Mortality Reductions
EV adoption reduces tailpipe emissions, leading to lower PM2.5 and ozone levels in urban areas. A study modeling 25% U.S. EV adoption found 437 fewer PM2.5-related deaths and 98 fewer ozone-related deaths annually due to reduced combustion emissions. Cities like New York, Chicago, and Houston show substantial benefits, with projected monthly mortality reductions of 796, 328, and 157 lives saved, respectively, through electrification. These benefits stem from decreased exposure to harmful pollutants linked to respiratory and cardiovascular diseases.
Energy Source Dependency
The health gains depend on the electricity grid’s cleanliness. At 75% EV adoption with low-emission energy sources, benefits peak: ~$70 billion in avoided damages annually. However, reliance on fossil-fuel-powered grids (e.g., coal) can worsen air quality. For example, Los Angeles saw mixed outcomes: a 29% EV share saved 104 lives, but full electrification with current infrastructure risks increased PM2.5 and ozone mortality.
Emerging Risks and Trade-offs
While EVs reduce air pollution, they introduce new challenges:
- Battery production and disposal contribute to hazardous waste and potential toxic exposure.
- Road safety may worsen if heavier EVs increase collision risks.
- Equity concerns arise if benefits disproportionately favor wealthier communities adopting EVs faster.
Key Considerations
- Grid decarbonization is critical to maximize health co-benefits.
- Localized risks (e.g., industrial pollution near battery plants) require mitigation strategies.
- Policy design must address disparities to ensure equitable health outcomes.
In summary, EVs improve public health in urban communities primarily through cleaner air, but their full potential depends on sustainable energy practices and holistic policy frameworks.
