Delivering packages with drones will scale back CO2 emissions inbound circumstances as compared to truck deliveries, a brand new study from University of Washington transportation engineers finds.

In a paper to be revealed in associate degree coming issue of Transportation analysis half D, researchers found that drones tend to own CO2 emissions blessings over trucks once the drones haven’t got to fly terribly way to their destinations or once a delivery route has few recipients.
