Can Driverless Cars Save the Planet?

According to a new study a system of autonomous taxis would both be cost-effective and greatly reduce per-mile emissions of greenhouse gases. The analysis found that the per-mile greenhouse gas emissions of an electric vehicle deployed as a self-driving, or autonomous, taxi in 2030 would be 63 to 82 percent lower than a projected 2030 hybrid vehicle driven as a privately owned car and 90 percent lower than a 2014 gasoline-powered private vehicle. Almost half of the savings is attributable to “right-sizing,” where the size of the taxi deployed is tailored to each trip’s occupancy needs.
