COMPUTING DEVICE, VEHICLE SYSTEM, AND METHOD

A computing device includes a CPU and a memory. A vehicle travels by consuming first electric power and second electric power. The first electric power is electric power, generation of a unit amount of which causes emission of a first amount of carbon dioxide. The second electric power is electric power, generation of a unit amount of which causes emission of a second amount of carbon dioxide, the second amount being smaller than the first amount. The CPU creates a charging plan based on a first ratio occupied by the second electric power in electric power supplied from a first charging position on a travel route of the vehicle.
