I have no separate energy meter, how do I enter energy consumption then

Rented premises without own connection: allocation key based on floor area

For rented office or business premises without own meter, fall back on an allocation key: the total consumption of the building, reduced to the share of floor area that the enterprise rents. The landlord or manager usually has the annual bill for the entire property; you divide that by the total rentable area and multiply it by your own meterage. That is not a measured value but an estimate, and that is permitted — the VSME-basismodule of EFRAG asks for total energy consumption, not for a certified measurement. Do mention that it is an allocation key and not a direct measurement, so the customer can decide for themselves whether that is sufficient for their purpose.

If even that property bill is missing, then the fallback option is an estimate based on comparable business premises: square meter prices for energy consumption per sector are public (CBS, trade associations, energy suppliers publish averages per type of premises). That figure is less well-founded than an allocation key based on an actual bill, but better than an empty cell. Always state in the explanation which method was used — allocation key based on bill, or sector average — because the customer who forwards the list wants to be able to see that distinction. This belongs to the question on total energy consumption per year, and not to scope 2, because without own meter and without own contract with a supplier there is usually no direct link to be made with a supplier-specific emission factor — that precision belongs to indirect emissions from purchased energy, not to the bare consumption figure.

Why an estimate is sufficient here: VSME B3 and the scope 2 classification of the GHG Protocol

The VSME-basismodule (indicator B3, energy consumption and mix) asks the enterprise to report what it can reasonably determine, including for shared or rented property; a pro-rata allocation by area is a common, defensible method within that module. The GHG Protocol makes a separate distinction in the scope classification between scope 1, 2 and 3 precisely because the accuracy of the source (own measurement versus estimate versus chain information) differs per scope — for the total consumption under B3 that distinction is not required, which makes the estimate here usable without anything being claimed that is not well-founded.
