Rideshare vehicles drive more miles every year than personal vehicles, the researchers write, “which means that electrifying these vehicles could have greater societal benefits.” Indeed, their analysis showed that electrified fleets had 40–45 percent lower greenhouse gas costs per trip compared to the gasoline-powered vehicles.They compared these results for a gasoline fleet and a battery-electric fleet. ![]() Using data collected in the Chicago area (one of the largest ridesharing markets, averaging 300,000 daily trips prior to the COVID-19 pandemic), they used a model that combined data from over a million Uber and Lyft trips taken on weekdays, weekends, and during different seasons with detailed geospatial vehicle routing data to analyze the costs of ridesharing services in terms of greenhouse gas emissions, traffic costs, and air pollution.Overall, making all rideshare vehicles electric would bring a societal benefit of only 3 percent per trip on average, according to the study published in the journal Environmental Science & Technology. The study found that all-electric ride-hailing fleets cut greenhouse gas emissions, but increase air pollution and traffic problems.What real-world societal and environmental benefits would electric fleets promise? The CMU and Michigan researchers conducted life-cycle comparisons based on real-world rideshare data to find out. The move is hailed for its impact on reducing greenhouse gas emissions, but a new collaborative study by researchers at the University of Michigan and Carnegie Mellon University shows that there could be some downsides. ![]() The two top ridesharing companies in the world, Uber and Lyft, have pledged to transition to fully electric vehicles in the US, Canada and Europe by 2030.
