Z is the sum for all gas types of (Q times EF_{j} divided by 1000)
Where:
Z is the scope 3 emissions measured in t.CO_{2}-e
Q is the quantity of natural gas (GJ)
EF_{j} is the emission factor for each gas type (j) which includes the effect of an oxidation factor (kg.CO_{2}-e/GJ)
Assumptions
None
Department of Environment and Energy
Electricity consumption amounts as provided by the property manager – expressed in kilowatt hours (kWh)
Calculation method
Z is Q times EF divided by 1000 times NLA_{frac}
Z is the full cycle (scope 2 and 3) emissions measured in t.CO2-e
Q is the quantity of electricity (kWh)
NLA_{frac} is the fraction of Net Lettable Area (NLA) occupied by EPA to the NLA for the whole property
EF is the full cycle (scope 2 and 3) emission factor for Victoria (kg.CO2-e/kWh)
Emissions associated with purchases of GreenPower are zero

Z is the sum for all flights of (Q_{i} times EF_{ij} divided by 1000)
Q_{i} is the distance travelled (km) for flight (i)
EF_{ij} is the emission factor for haul type (j), which includes the effect of radiative forcing, for flight (i) (kg.CO_{2}-e/km)
Haul types are based on distances set by the United Kingdom (UK) Department for Environment, Food & Rural Affairs (DEFRA).
Emission factors for air travel are inclusion of radiative forcing
