Emission factors
Emission factors are used by BuildingMinds to calculate the CO2 emissions. For more information, on how carbon emissions are calculated, see Operational carbon emissions calculation.
All decimal numbers in this section are displayed with a decimal point.
Electricity from grid (normal contract)
All emission factors are in kgCO2 e/kWh.
