Scope 3 Supply Chain Calculator

The Scope 3 Supply Chain calculator has a number of configurations that MUST be specified for emissions calculations to occur. These are set in an Activity Calculator Configuration with an effective month range.

• Emission Factor Set (emission factor set containing the relevant factor)
• Factor Lookup (lookup key for the relevant emission factor)
• Scope 3 Calculation Method (Note: this selection has no impact on the emissions calculation but features in reporting)
• Input to use to determine emissions
  • co2e : the input value of t CO2-e will be used as the emissions and no calculation or factor lookup will occur.
  • Quantity : the input value of Quantity will be used with an emission factor selected by the Factor Lookup and the activity unit
  • Cost : the input value of Cost will be used with an emission factor selected selected by the Factor Lookup and unit = Dollars

When entering data for an activity configured with the Scope 3 Supply Chain calculator, there are three available inputs. The input specified in Input to use to determine emissions MUST be specified and cannot equal zero.

t CO2-e = A<unit> * EF<unit> / 1000
where
A = amount of unit (A may be Quantity or Cost)
EF = Scope 3 emission factor (kg CO2-e / unit) (unit may be the activity unit or Dollars)

If t CO2-e is provided but Input to use to determine emissions is not “co2e”, the entered value will be saved but will not be used in emissions calculation.
