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

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

Where two Cascale papers differ

What to do about the gap

The same kWh, two different answers

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.
