Where 2.55 comes from
JRC-IDEES prints this factor as a single figure, with no parts to add up.
Reporting this tonne-kilometre under the GHG Protocol
Scope 3, category 4 2.55
You pay a carrier to bring goods in, or to move them between your own sites. All of it goes in upstream transport.
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
- 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
- Fossil only
- All of it is CO₂

Per tonne, per vehicle or per passenger
One trip, three ways to count it. Pick the unit you have a number for.
One tonne of goods carried one kilometre. Use it when you know what the shipment weighs.
2.5512 t over 300 km is 3,600 t.km, so 9,173 kg CO₂e
One person carried one kilometre, on a bus, a train or a flight. It never applies to goods.
Not for goodsAll values
24 values, one per year back to 2000. Every one is fossil only, so the years compare directly.
2023 onwards2.55Default value
- Default: what search and the API return when you ask for nothing specific
What this number covers
The path of one tonne-kilometre, from the oil well to the delivered load.
Vehicle operation
Burning the fuel in flight, spread over the average load
Included2.55Your shipment
1 tonne moved 1 km. The factor is per tonne-kilometre.
= 2.55
Outside this boundary
- Upstream fuel (well-to-tank)
- Building the aircraft
- Airports
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: Fossil onlyFossil carbon only: biogenic CO₂, methane from biogenic sources and land-use change are left out. Learn more
- Fossil CO₂2.55
The CO₂e counts fossil carbon only; biogenic CO₂, biogenic methane and land-use carbon are left out.
