Emission factor from SSB

CO gas - Boilers

Norway · Combustion · Any year

Each kilogram of this fuel counts as 1.57 kg CO₂e from burning it. open-climate.ai worked this figure out from values published by SSB, for use in any year.

Where 1.57 comes from

Derived by open-climate.ai

open-climate.ai adds up the gases SSB publishes, each weighted by its warming potential.

Reporting this kilogram under the GHG Protocol

Scope 1 1.57

You burn the fuel, so its combustion is your Scope 1.

What this number covers

The path of one kilogram of this fuel, from the well to your flame.

Your record
1 kg in your records. The factor is per kg.
Burning it
In your boiler, furnace or engine: CO₂, with a little CH₄ and N₂O
1.57

= 1.57 per kg

Outside this boundary

Producing and delivering the fuel
Making the boiler that burns it
Building the pipelines and the network

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

Gases

Basis: Excl. biogenic CO₂

Fossil CO₂1.57100%
Methane (CH₄)0.0002
Nitrous oxide (N₂O)0.000191

Σ 1.57 + 0.0002 + 0.000191 = 1.57.

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 SSB's record to a comparable factor

SSB 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.
