What this number covers

The path of 1 km, from the oil well to the end of the trip.

  1. Vehicle operation

    Burning the fuel on the road, spread over the average load

    Included0
  2. Effect at altitude

    Contrails and other warming from burning fuel high up. Flights only.

    Not applicable on the road
  3. Your record

    1 km in your records. The factor is per km.

    = 0

Outside this boundary

  • Upstream fuel (well-to-tank)
  • Building the vehicle
  • Roads and depots

This factor counts the fuel the vehicle burns, not the vehicle itself or the infrastructure it runs on. Some libraries price building the vehicle as a factor of its own.
