- LoadHow full a lorry, train or ship runs with goods. A passenger factor counts passengers or vehicles, not tonnes, so no load applies.
- Not applicable
- Vehicle sizeThe vehicle's class, by weight or capacity. UOS does not say which size this factor assumes.
- Not stated
- Distance bandFlights are priced by distance band, because take-off and climb burn a large share of a short flight's fuel. Road, rail and sea factors apply to a trip of any length.
- Any distance, not banded
- Cabin classA business seat takes more of the cabin than an economy one, so it carries more of the flight's emissions. First class on a long-haul flight counts four times economy.

Where 0 comes from
UOS prints this factor as a single figure, with no parts to add up and no split by gas.
Reporting this kilometre under the GHG Protocol
Scope 3, category 6 0
A trip for work is business travel, Scope 3, category 6, whoever books it.
The factor, standardised
Every factor on open-climate.ai answers the same questions in the same words, whatever the publisher. Open any ⓘ for the definition.

Combustion · Excl. biogenic CO₂
- BoundaryCombustionDirect emissions from burning the fuel at the point of use, in a boiler, furnace, engine or vehicle (for a vehicle, tank-to-wheel). Learn more
- Combustion
- Fuel combustion
- GWP methodWhich IPCC assessment report's warming potentials convert each gas to CO₂e, and over how many years the warming is counted (GWP100: 100 years). Learn more
- None: the value counts CO₂ alone
- CO₂ weighs 1 in every IPCC report, so no GWP applies
- CO₂e basisWhich carbon the CO₂e counts. Fossil only leaves out biogenic CO₂ and land use; net total counts every pool, net of removals. The same activity on two bases is two different numbers. Learn more
- Excl. biogenic CO₂
- All of it is CO₂

What this number covers
The path of 1 km, from the oil well to the end of the trip.
Vehicle operation
Burning the fuel on the road, spread over the average load
Included0Effect at altitude
Contrails and other warming from burning fuel high up. Flights only.
Not applicable on the roadYour record

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.
From UOS's record to a comparable factor
UOS publishes this factor as one record. Here is each field as printed and what open-climate.ai made of it.
