Performing audit trails

You can perform an audit trail for calculated emission values on the scope 3 summary dashboard.

About this task

The emission factor used depends on whether a fallback spend-based factor is applied or if the supplier has provided a product carbon footprint (PCF) value. ESCI uses Eora66 MRIO emission factors, which are based on U.S. dollars. Therefore, the product's monetary value and its currency must also be in U.S. dollars for the emission calculation to work correctly. The currency used for the order line value does not affect the emissions calculation.

When a supplier's product is marked as material, the system automatically creates a compliance record to store the emission factor. This factor is either supplied by the vendor or assigned by default. Once the order line is processed, the system calculates the total emissions for that order.

Multiple factor values might apply to a product if no supplier-specific Product Carbon Footprint (PCF) value is provided. For more information about factor precedence, see How factors are prioritized and applied?.

Procedure

  1. From the side navigation menu, click Scope 3 summary.
  2. For a spend-based location entry and click View details to drill down to the Emissions details page for the location.
  3. Review a spend-based factor calculation. In the Order line emissions detail table, click an order line to view its factor details. Review the following attributes:
    Source
    The factor set that was used in the emissions calculation. For spend-based fallback calculations that were made by Envizi™ Supply Chain Intelligence, the factor set is Eora66 MRIO.
    Factor value
    The factor from the Eora66 database that is used in the calculation and it is based factor category and region.

    The quantity is multiplied by the cost to determine the total spend on an order line. The total spend is multiplied by the factor value to produce the emissions total.

  4. Review a supplier-based factor calculation. In the Order line emissions detail table, click an order line to view its factor details. Review the following attributes:
    Factor source
    Labeled as supplier.
    Factor value
    The PCF factor this is provided by the supplier in their PCF upload.
    • If the factor is per cost, then quantity is multiplied by the cost to determine the total spend on an order line. The total spend is multiplied by the factor value to produce the emissions total.
    • If the factor is per unit, then quantity is multiplied by the factor value to produce the emissions total.
