Functional unit
State the service and reference flow.
This screening candidate fixes the functional unit at 1 passenger-km. A future model must derive vehicle and battery reference flows from occupancy and lifetime.
Check your definitionWhat, how much, how well, and for how long?
The functional unit states the transport service, while the reference flow connects that service to process amounts.
