# Will the Higg Facility Environmental Module (Higg FEM) use my own electricity emission factor, or the national one?

Canonical: https://senseible.earth/answers/higg-fem-uses-country-grid-factor-not-yours

For electricity from the national grid, the Higg FEM uses its own country figure and you cannot change it. The 2026 guide says a custom factor you type in is not used, for now. So your own total will not match the form's, and you cannot rebuild its figure by hand.

## What the guide says

- The form asks whether you use electricity other than from the national grid, for example through a direct power purchase agreement, and whether you know that source's emission factor. Answer No if you buy from the national grid.
- Even if you answer Yes and type in a factor, the guide says the form allocates the standard country factor from FEM 2024 onwards. It will not use the custom factor until specifically indicated in the future.
- An emission factor is a conversion number, like a market rate per kilo. It turns units of electricity into kilograms of carbon dioxide equivalent (CO2e). Your own records use one rate and the form uses another.

## Where two Cascale papers differ

- The 2024 calculations paper still describes an override: the grid figure is replaced by the facility's own if it answered Yes. It also says typed values above 1.6 or below 0 kilograms of CO2e per kilowatt hour (kWh) are not used.
- The 2024 paper adds that country factors are updated each cycle and may not be disclosed, because they are licensed from the International Energy Agency. So the form's electricity figure cannot be rebuilt by hand.
- Where they differ, follow the 2026 guide, and ask Worldly support if your verifier says otherwise.

## What to do about the gap

- Enter your kWh exactly as billed. That is the number the verifier checks against your bills, not the emissions.
- Keep your own record at the Central Electricity Authority grid figure for the bill's financial year (FY). For FY 2025-26 that is 0.675 kilograms of carbon dioxide (CO2) per kWh.
- Do not alter your kWh to make the form's emissions match your own.

## The same kWh, two different answers

- Your own record: 1,000,000 kWh x 0.675 = 675,000 kilograms, which is 675 tonnes of CO2
- The Higg FEM total for the same kWh: calculated by the form with its own country figure, which may not be shown to users
- Enter 1,000,000 kWh in both. Only the factor differs.

The kWh figure is an example. 0.675 is the Central Electricity Authority figure for FY 2025-26.

## What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so the kWh on each bill are in one place to total. A Higg FEM total will differ because the form uses its own factor, and the self-serve product does not enter anything into it.

Last reviewed 2026-11-07. The 2026 guide and the 2024 calculations paper differ on custom factors; this page follows the guide. The grid factor 0.675 is the Central Electricity Authority figure for FY 2025-26.
