Ride-sharing services currently result in 69% more emissions, on average, than the trips they displace, according to a recent study by the Union of Concerned Scientists.But, if the ride-sharing vehicles were electric, it's a whole different story. Replacing one gasoline-powered ride-sharing car with an electric vehicle (EV) has three times the climate benefit as replacing a personal car with an EV.Some companies like Cruise and Aurora go even further, developing electric autonomous fleets, which could further reduce the carbon footprint of ride-share vehicles.Climate Now spoke with Dave Rubin, Head of Policy Research at Cruise, a self-driving, ride-sharing service, to understand how electric and autonomous vehicles could help us decarbonize road transportation, and the challenges ahead for wide-scale adoption.Follow us on Twitter, LinkedIn, Facebook, and Instagram.Contact us at contact@climatenow.comVisit our website for all of our content and sources for each episode.
