A new study from the University of Houston examined the possible health benefits of vehicle electrification scenarios across four major U.S. cities — Houston, Los Angeles, New York, and Chicago — by looking at projected changes in air pollution.
In short, it’s good news — and it’s also complicated.
The study, published in the journal Science of the Total Environment, found higher rates of electrification would spell nearly unequivocal good news for three of the four cities: Houston, New York, and Chicago.
In a full electrification scenario, Houston could prevent 157 premature deaths monthly. Meanwhile, New York and Chicago could avoid a respective 796 and 328 premature deaths per month, according to the analysis posted by Phys.org.Â
These cities could also enjoy economic benefits related to health outcomes; the study projected savings anywhere from $51 million to $249 million a day.
“Our findings indicate vehicle electrification generally contributes to reducing greenhouse gas emissions, improving air quality, and lowering the mortality rate associated with exposure to toxic air pollutants,” said Ali Mousavinezhad, one of the researchers, per Phys.org.
However, things were more complicated for Los Angeles. There, partial electrification could save over a thousand lives a year, but full electrification may actually increase mortality rates. Phys.org explained that it’s due to the area’s weather, atmospheric chemistry, and geography. The surrounding mountains often create trapped pockets of air, increasing the density of certain air pollutants.
“This underscores the need for region-specific environmental regulations,” Mousavinezhad emphasized.
Fellow researcher Yunsoo Choi agreed, telling Phys.org, “Each city requires unique regulations or strategies, including different scenarios for the adoption of electric vehicles, to reduce concentrations of these pollutants and greenhouse gases effectively.”
And with the adoption of electric cars increasing each year — according to MarketWatch, EV sales in the US increased by more than 60% between 2022 and 2023 — it will be critical to know how these trends will impact human health.
“The findings of this study will assist policymakers in tailoring their regulations to the specific characteristics of different regions to enhance quality of life,” Ali concluded in the Phys.org report.

A new study from the University of Houston, published in the journal Science of the Total Environment, explores the health benefits of vehicle electrification in four major U.S. cities: Houston, Los Angeles, New York, and Chicago. The findings suggest significant health and economic benefits for Houston, New York, and Chicago, with full electrification potentially preventing hundreds of premature deaths monthly and saving up to $249 million per day in health-related costs.
However, the situation is more complex for Los Angeles, where full electrification could increase mortality rates due to the city’s unique weather, atmospheric chemistry, and geography, which trap air pollutants. This highlights the necessity for region-specific environmental regulations. Researchers emphasize that each city requires tailored strategies for electric vehicle adoption to effectively reduce pollutants and greenhouse gases.
As electric vehicle sales continue to rise, understanding these impacts is crucial for policymakers aiming to enhance air quality and quality of life through targeted regulations.
