New findings from researchers at the University of California, Los Angeles, indicate that the spread of electric vehicles in urban settings can yield benefits for residents who cannot afford private EV ownership. The results, published in Nature Communications, illuminate how greener transportation options influence air quality across diverse neighborhoods in a major metropolitan area.
The study examined how electric cars alter environmental conditions in economically challenged parts of Los Angeles. Computer modeling demonstrated that increasing the share of electric vehicles on highways running through deprived districts reduced local pollution by a greater margin than in more affluent areas. Specifically, these corridors showed pollution improvements that exceeded those observed across other parts of the city by a notable margin, though overall ecological health in the disadvantaged zones remained below targets due to the continued presence of gasoline and diesel engines and the proximity to heavily trafficked roadways.
According to the analysis, nearly half of Los Angeles County’s population of about 10 million people resides in disadvantaged neighborhoods. Yet these communities account for a disproportionately small segment of electric vehicle registrations, underscoring a gap between need and adoption.
The authors of the report recommend that public authorities prioritize electrification beyond passenger vehicles. Transitioning medium- and heavy-duty trucks to electric propulsion and other low-emission fuels could address the most pollution-intensive emissions since commercial and freight transport contribute heavily to urban air quality challenges.
Looking ahead, researchers aim to identify barriers beyond cost that prevent lower-income residents from embracing electric cars. They plan to explore factors such as access to charging infrastructure, reliability of power supply, workforce awareness, and the perceived practicality of EVs in different neighborhoods.
