Sometimes a supplier may provide you with the actual emissions associated with your use of their product or service over your assessment period.
In Sumday, you can enter this supplier-provided emissions figure directly, using our Sumday Calculated dataset with a 1:1 CO2e emission factor. This converts your entered value directly into kg CO₂e, ensuring the entry is traceable and consistent with the rest of your data.
Note: This is different from using/creating a supplier-specific (primary) emission factor.
A supplier-specific emission factor is used when the supplier provides a factor (e.g., 0.35 kg CO₂e per $ spent or KG purchased), and you calculate your emissions by multiplying that factor by your activity data. You can do this by uploading a custom emission factor for the supplier into Sumday.
Supplier-provided emissions is when the supplier has already calculated the emissions associated with your use of their product or service for a specific reporting period and gives you a total emissions figure.
Steps to enter supplier-provided emissions
Go to your Emission Assessment Settings (icon with 3 lines and 3 circles in the top right of the assessment).
Add the Sumday Calculated Emission Factor dataset to your Scope 3 activity dataset options and Save changes.
In the Accounting tab, go to the relevant Scope 1, 2 or 3 category where you want to record the supplier-provided emissions.
If you have an existing transaction for the supplier, switch it to an Activity-based calculation and choose kg as the unit of measurement.
If you don’t have a transaction, navigate to the Activity section of the GHG category and click the + icon on the right-hand side to add a custom non-financial activity data input.
Select the Sumday Calculated emission source and choose the Custom (Direct CO₂/CO₂e Entry) factor.
Enter the emissions figure provided by the Supplier (e.g., 7,400 kg) into the Quantity field.
(Optional) Add a note explaining that the figure comes from supplier-provided data.
