Self-Driving Taxis Would Dramatically Cut Carbon Emissions, Analysis Finds

By 2030, self-driving electric taxis could cut greenhouse gas emissions from car travel in the U.S. by up to 94 percent, if they were to replace conventional personal vehicles, according to an analysis published in the journal Nature Climate Change.  Autonomous taxis are projected to cut carbon emissions primarily through a process known as "right-sizing," or deploying a car that is specifically tailored to match occupancy needs of each particular trip.  Right-sizing is cost-effective for both the fleet owner and for passengers, the researchers say, and companies and research groups are currently exploring how to efficiently manufacture small one- and two-seat vehicles. Optimal routing, smoother acceleration and braking, and a cleaner electric grid in 2030 would also contribute to lower carbon emissions.  Autonomous taxis are projected to reduce emissions by 63 to 82 percent compared to hybrid cars likely to be on the road in 2030, and by 94 percent over 2014 gasoline-powered models, the study found.
