- 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. ISPRA 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 0.267 comes from
open-climate.ai adds up the gases ISPRA publishes, each weighted by its warming potential.
Reporting this kilowatt-hour under the GHG Protocol
Scope 3, category 6 0.267
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.

- 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
- IPCC AR6, 100-year horizon
- Not on the record; set from ISPRA's method notes
- CO₂e basisWhich carbon the CO₂e counts. Fossil only leaves out biogenic methane, land-use change and biogenic CO₂; excl. biogenic CO₂ counts biogenic methane but not the other two; net total counts every pool, net of removals. The same activity on two bases is two different numbers. Learn more

What this number covers
The path of one kilowatt-hour, from the oil well to the end of the trip.
Vehicle operation
Burning the fuel on the road, spread over the average load
Included0.267Effect at altitude
Contrails and other warming from burning fuel high up. Flights only.
Not applicable on the roadYour meter
1 kWh used. The factor is per kWh measured here.
= 0.267
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.
Gases in vehicle operation
Basis: Net totalEvery carbon pool, biogenic and land use included, net of removals, so it can sit below the fossil figure, or even below zero. Learn moreFossilBio CH₄Land useBio CO₂full carbon balance
- Carbon dioxide (CO₂)0.26599.4%
- Methane (CH₄)0.0008810.3%
- Nitrous oxide (N₂O)0.0007680.3%
Σ 0.265 + 0.000881 + 0.000768 = 0.267.
Each gas is converted to CO₂e with AR6 100-year warming potentials; biogenic and land-use carbon are counted.
