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
0.034

= 0.034 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

NAEI counts only burning the fuel, not producing and delivering it or the things built to extract, move and burn it.

Gases

Basis: Excl. biogenic CO₂FossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories

Methane (CH₄)0.0388.4%
Nitrous oxide (N₂O)0.0039311.6%

Σ 0.03 + 0.00393 = 0.034.

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.

Checks this factor passed

The two gases add up to the total: CH₄ and N₂O.
One value per year from 1990, no gaps, no overlaps.
Printed value multiplied by 3.6 to serve it per kWh.
Printed total restated by open-climate.ai from AR5 to AR6 with the published gas split: 0.0341 → 0.034 kgCO₂e/kWh.
Unit, region, boundary and method mapped to fixed code lists.
