In this lesson, you'll learn to set up source data related to purchased goods and services using supplier-specific methods.
Calculating GHG Scope 3.1 Emissions for Purchased Product Footprint using Supplier-specific Method: Process Flow
To calculate GHG Scope 3.1 emissions for a purchased product footprint using the supplier-specific method, first upload the required master data to define organizational boundaries. Then, set the organizational boundary and select relevant value chain steps for product acquisition. These initial two steps are same as those used in average-data and spend-based methods.
Now, you can attain the primary emission factors from the supplier. You can use the Manage Supplier Footprint app to import the supplier footprints either via excel or SAP Sustainability Data Exchange. If you're using excel, you can gather the footprint data from the suppliers via offline channels and upload the respective excel to obtain the footprint data in the Manage Supplier Footprint app. However, if you are importing via SAP Sustainability Data Exchange, then you can electronically transfer sustainability data of suppliers to your system. Using SAP Sustainability Data Exchange standards ensure that the data you receive is consistent, accurate, and easy to integrate into your SAP systems.
Note
If your suppliers are onboarded in the SAP Sustainability Data Exchange network, use Partnership for Carbon Transparency (PACT) format to exchange data.For obtaining supplier data via SAP Sustainability Data Exchange, you need to setup the product and supplier master data such as product names, descriptions, categories, and associated emission factors and details about each supplier in SAP Sustainability Data Exchange. Then you onboard the suppliers to the SAP Sustainability Data Exchange system and request them to provide detailed information on the carbon footprint of the products they supply.
Once suppliers report their product carbon footprints in SAP Sustainability Data Exchange, there is an automatic sync between SAP Sustainability Data Exchange and Manage Supplier Footprint app in SAP Sustainability Footprint Management. Therefore, the Manage Supplier Footprint app gets updated with pending requests in SAP Sustainability Footprint Management. After that, you can assign the received footprint data to the relevant plant and then review the footprint to release it. The newly updated emissions data is now accessible in the Manage Purchased Product Footprints app.
Next, follow the same steps as in the average-data and spend-based calculation methods to upload or replicate all goods receipt transactions from suppliers for the relevant periods. Then, create a periodic inventory of your footprints. Perform calculations on the recorded footprint data to generate results. Review these calculated results to ensure accuracy and completeness.
