An increasingly prominent option is the use of uncrewed aerial vehicles or drones.  This week research comparing the environmental impact of different forms of last-mile delivery was published in the scientific journal Patterns. Researchers from Carnegie Mellon University compared the energy consumption of quadcopter drones against diesel and electric medium-duty trucks, small vans, and electric cargo bicycles on a per-package basis. They found that greenhouse-gas emissions per parcel were 84% lower for drones than for diesel trucks. Unsurprisingly, drones consumed…
