Where 0.137 comes from
Japan MOE prints this factor as a single figure, with no parts to add up.
Reporting this kilowatt-hour under the GHG Protocol
Scope 2 + 3.3 Energy upstream 0.137
This one figure covers both together; no split between them is given.
You buy the energy, so its generation is your Scope 2.
The fuel behind it and the energy lost on the way to you are Scope 3, category 3.
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.

- BoundaryGeneration and network lossesDelivered without its upstream chain: one unit of a delivered energy carrier (electricity, steam or hot water, chilled water) priced as the generation or heat production plus the transmission and distribution losses between the plant and the point of use, without the well-to-tank chain of the fuel the plant burns.

- Generation and network losses
- Calculation approachLocation-based uses the average grid mix where the electricity was consumed; market-based uses the supplier contract or the residual mix. The two can differ by an order of magnitude on the same kilowatt-hour, so they are never interchangeable. Learn more
- Market-based, supplier-specific mix
- 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 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 heat, from the fuel to your meter. Not every step on it is counted; what is left out is listed below.
Heat generation
Producing the heat and steam at the plants that feed the network
Included, not split outNetwork losses
Heat lost in the pipes between the plant and your meter, which still had to be produced
Included, not split outYour meter
1 kWh used. The factor is per kWh measured here.
= 0.137
Outside this boundary
- Producing and delivering the heat plants' fuel
- Building the heat plants
- Building the heat network
Japan MOE counts burning fuel at the heat plants, not producing and delivering that fuel or building the plants.

The CO₂e counts fossil carbon only; biogenic CO₂, biogenic methane and land-use carbon are left out.
