Where 0.00743 comes from
open-climate.ai adds up the gases OCCC publishes, each weighted by its warming potential.
Reporting this kilogram under the GHG Protocol
Scope 1 0.00743
You burn the fuel, so its combustion is your Scope 1.
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 OCCC'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 kilogram of this fuel, from the crops or residues it is made from to your engine or boiler.
Your record
1 kg in your records. The factor is per kg.
Burning it
In your engine or boiler: mostly CO₂ the plants took up as they grew, with a little CH₄ and N₂O
0.00743
= 0.00743 per kg
Outside this boundary
- Producing and delivering the fuel
- Purchased electricity and heat
- Making the boiler that burns it
- Building the pipelines and the network
OCCC counts only burning the fuel, not producing and delivering it or the things built to extract, move and burn it.
Gases
Basis: Excl. biogenic CO₂Biogenic CO₂ and land-use change are left out; fossil CO₂, the other greenhouse gases and methane from biogenic sources are counted. Learn moreFossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories
- Biogenic CO₂1.1299.3%
- Nitrous oxide (N₂O)0.006440.6%
- Methane (CH₄)0.00099
Σ 0.00099 + 0.00644 + 1.12 = 1.13197, more than the 0.00743 total OCCC prints.
Each gas is converted to CO₂e with AR6 100-year warming potentials; biogenic CO₂ and land-use carbon are left out, while methane from biogenic sources is counted.
From OCCC's record to a comparable factor
OCCC publishes the inputs; open-climate.ai computed this value from them. Here is each field as printed and what open-climate.ai made of it.
