In order to initiate the Carbon emissions tracking in procurement for Parts, users must add carbon emissions values to the specific Supplier for Purchase Part in the Emissions tab.
Use this activity to add emissions details to the Supplier for Purchase Part using any of the three sources; Third Party, Supplier or Manual.
When the source is set to Manual and the Emission Calculation Method is set to Spend,
the user must ensure the values entered are emission values per unit of currency in kgCO2e. If the Emission
Calculation Method is set to Activity user has the option to add emission values either per Purch UoM
,Net Weight(kg) or Net Volume(m3) on Supplier for Purchase Part. Further for Activity based Emissions user needs to
enter the LCA Activity which refers to specifying the phase or scope within the life cycle for which emission
calculations are made, such as cradle_to_gate, cradle_to_processing_gate, cradle_to_farm_gate, or upstream
activities. This allows emissions data to be mapped and reported according to specific life cycle segments,
improving granularity and accuracy in carbon footprint reporting.
Information received from B2B suppliers also align with the same end output structure as described above. If the Emission Calculation Method is set to Spend, a request will be sent to the B2B portal indicating the supplier emission data requested is from Spend basis. Similarly if the Emission Calculation Method is set to Activity, the Activity Emission Basis will default to Purch UoM. The data received from the B2B portal will be shown on the Substance group level and Substance level per Purch UoM.
If the Source for Emissions is set to Third Party and Emission Calculation Method is set to Spend, the data received from Third Party Integration is shown per the Unit Price indicated for the Supplier for Purchase Part on General tab. If the Source for Emissions is set to Third Party and Emission Calculation Method is set to Activity, then Emissions Per Unit on the Substance Group & Substance level will be per defined Purch UoM, Net Weight(kg) or Net Volume(m3) on the Supplier for Purchase Part on General tab.
For activity-based emissions, the Third Party integration currently supports only the following units of measure
(UoMs):
Weight UoMs: "g", "kg", "t", "ton", "lb"
Volume UoMs: "ml", "l", "m3", "cubic_foot", "gallon_us",
"bbl"
Other UoMs: "PCS", "pcs"
The system verifies that the Base Unit of Measure (UoM) corresponding to the selected UoM on the Supplier for
Purchase Part matches one of the units supported by the Third Party integration. Emissions fetching proceeds
only when this condition is satisfied.
In summary when Emission Calculation Method is set to Spend the Emissions Per Unit on the Substance Group & Substance level will be per the total Unit Price defined in the General tab to show the Total Emission value for the part per Purchase UoM. When Emission Calculation Method is set to Activity , the price of the part has no effect on it. Rather the system will consider the Purch UoM, Net Weight(kg) or Net Volume(m3) as the Activity Emissions Basis and run the calculation accordingly. (eg: If the Activity Emissions Basis is set to Net Weight then if the Supplier for Purchase Part has a defined Net Weigth of 10kg Emissions Per Unit on the Substance Group & Substance level would be per a Net Weight of 10kg)
On any combination above system will keep the Emissions Per Unit on the Substance Group & Substance level per Purchase Unit of Measure on Supplier for Purchase Part.
Emission Remark is typically a third party indicator of the accuracy of the data received from Third Party integrations. It is important for the user to manually review this data to ensure it corresponds correctly with the Part description and its associated Procurement Category Assortmnet. If the emission data does not adequately match, the user should consider assigning the record to a more descriptive Procurement Category Assortment node that better details the product or possibly improve the Part Description, or alternatively, use a different Emission Calculation Method to improve accuracy.
The carbon emissions per Supplier per Purchase Part will be defined with the selected source.
When a Substance Group is set as the Default Configutation for Emissions, the Total Emission value will be updated with the Emissions Per Unit of the Substance Group. This value will be used as the default total emissions value for the Supplier for Purchase Part system-wide.
