The adoption of electric vehicles (EVs) in urban areas has a significant positive impact on reducing asthma rates, particularly childhood asthma, due to the reduction in harmful air pollutants emitted by gas-powered vehicles.
How EV Adoption Affects Asthma Rates
- Reduction in Air Pollutants: Gas-powered vehicles emit harmful pollutants such as nitrogen oxides (NOx) and particulate matter (PM2.5), which are strongly linked to asthma development and exacerbation in urban populations. EVs produce zero tailpipe emissions, leading to cleaner air and lower exposure to these pollutants.
- Decrease in Asthma Incidence and Attacks:
- Studies show that increasing EV adoption correlates with fewer asthma-related emergency visits. For example, in some urban regions, adding 20 EVs per 1,000 people led to a 3.2% reduction in asthma emergency visits.
- A 100% transition to EVs could prevent tens of thousands of asthma-related emergency department visits annually—one study estimates about 57,200 fewer visits in the U.S.
- Replacing around 50% of gas-powered vehicles with EVs could significantly cut childhood asthma cases linked specifically to vehicle exhaust pollution.
- Quantified Health Benefits:
- In Houston, theoretical models predict that EV adoption between 50% and 95% could reduce NOx by 1 to 4 parts per billion, preventing around 7,500 asthma exacerbations.
- The University of Toronto study found that each additional 1,000 internal combustion engine (ICE) vehicles sold is associated with about one additional new case of childhood asthma, highlighting that reducing ICE vehicle numbers through EV adoption directly lowers asthma incidence.
Summary
In urban environments, where vehicle emissions are a major contributor to air pollution and asthma risk, transitioning from gas-powered cars to electric vehicles reduces emissions of nitrogen oxides and particulate matter. This reduction leads to lower rates of asthma incidence and emergency visits related to asthma, with significant impacts on childhood asthma in particular. Research indicates that even partial EV adoption (around 50%) can drastically improve respiratory health outcomes for urban populations.
Thus, widespread EV adoption in cities represents an effective public health strategy to reduce asthma prevalence and morbidity related to air pollution from vehicles.
