Where 0.000983 comes from
open-climate.ai adds up the gases IPCC publishes, each weighted by its warming potential.
Reporting this kilowatt-hour under the GHG Protocol
Scope 1 0.000983
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 IPCC'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 of this fuel, from the wood it is made from to your boiler.
Your meter
1 kWh used. The factor is per kWh measured here.
Burning it
In your boiler or stove: mostly CO₂ the wood took up as it grew, with a little CH₄ and N₂O
0.000983
= 0.000983 per kWh
Outside this boundary
- Producing and delivering the fuel
- Purchased electricity and heat
- Making the boiler that burns it
- Building the pipelines and the network
IPCC counts only burning the fuel, not producing and delivering it or the things built to extract, move and burn it.
Gases
Basis: Fossil onlyFossil carbon only: biogenic CO₂, methane from biogenic sources and land-use change are left out. Learn moreFossilBio CH₄Land useBio CO₂EN 15804 GWP-fossil
- Nitrous oxide (N₂O)0.000983
Each gas is converted to CO₂e with AR6 100-year warming potentials; only fossil carbon counts, so biogenic CO₂, biogenic methane and land-use carbon are left out.
From IPCC's record to a comparable factor
IPCC 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.
