With this blog post I'd like to show you how to setup a GHG scenario for stationary combustion using SAP EHS, Environment Management using equations from a compliance requirement. You start with creating a location and then the compliance scenario for yearly CO2 equivalent calculation is created with a data collection for collecting natural gas and the calculation for the CO2 equivalent based on equations from a compliance requirement.

The calculation is created according the Guideline for GHG Emission Inventories in SAP EHS so that the results can be used with:

Preconditions



  1. A S/4HANA Cloud, public edition, S/4HANA Cloud, private edition or S/4HANA in a recent version.

  2. SAP EHS, Environment Management licensed and activated in the system.

  3. Default content for compliance requirements.

  4. A user with business partner and employee assigned for use as Environmental Manager and Environmental Technician (given for S/4HANA Cloud business users).

  5. The standard data classifiers for GHG emissions are imported or manually created in your system.


Disclaimer


This scenario uses sample content that is shipped with SAP EHS, Environment Management that contains hard-coded values for greenhouse warming potential and emission factors. In a production scenario, you will need to review and most probably create your own compliance requirements for your specific data.

Create a Location for GHG Data


Currently, GHG data needs to be assigned at a location of type Site or Plant to be recognized as GHG data. If you want to import data into SCT, you have to maintain a Plant ID for the location as well. The Plant ID is used as the id for the node in SCT's Business Location hierarchy.

Let's create such a location:

  1. Open your Fiori launchpad.

  2. Open application Manage Locations.

  3. Choose Edit Location Structure.

  4. Navigate to the location, where you want to create your GHG location as a child node. Select the location.

  5. Choose New to enter the Create Location screen.

  6. For group Identification, enter the follow values.

  7. Enter the Location name, for example Boston.

  8. Set the Location type to Site (EHFND_LTY_SI). Alternatively, you can use Plant (EHFND_LTY_PLNT).

  9. Enter the Revision Start Date, for example 01/01/2023.

  10. For group Organizational Information, enter the following value.

  11. Enter the Plant ID for the location, for example 1742.

  12. Add further information if needed.

  13. Choose tab Persons Responsible.

  14. Open the value help on the empty field for Name in the first row of the table Persons Responsible by Roles.

  15. Search for the name of the environmental manager, select them and confirm with OK.

  16. Set field Role in the first row to Environmental Manager.

  17. Open the value help on the empty field for Name in the second row of the table Persons Responsible by Roles.

  18. Search for the name of the environmental technician, select them and confirm with OK.

  19. Set field Role in the first row to Environmental Technician.

  20. Choose Save.

  21. Choose Return to Location Structure to go back to the calling app.

  22. You should see now your location underneath it's parent.

  23. Choose the newly created location to open it again.

  24. Choose Set Status → Active to activate it.

  25. Choose Save.


Create Your Compliance Scenario


Next, you create the compliance scenario for collecting source data and calculating GHG data:

  1. Open your Fiori launchpad.

  2. Open application Manage Compliance Scenario.

  3. Choose tab Display by Location.

  4. Find your location in the Location Structure and select it.

  5. Choose Create → Compliance Scenario to enter the Create Compliance Scenario screen.

  6. For group Basic Information, enter the following values.

  7. Set Valid From to the start date of your new compliance scenario, for example 01/01/2023.

  8. Set Scenario Name to your desired name, for example Facilities Heating.

  9. Add the to be used Requirement Paragraphs as follows.

  10. Open the value help for New Entry to add a compliance requirement paragraph.

  11. Enter Predefined Equations for Greenhouse Gas Calculations based on Title 40 Part 98 in the Name filter field.

  12. Choose Go.

  13. Expand the table entry Predefined Equations for Greenhouse Gas Calculations based on Title 40 Part 98 and select Subpart C, Tier 1 Calculation Methodology.

  14. Choose OK.

  15. Choose Save to create the compliance scenario and move over to the Edit Compliance Scenario screen.


Add Data Collection for Collecting Natural Gas Consumption



  1. Do the following actions on the edit compliance scenario screen for your new compliance scenario.

  2. In the Activities area, choose Add → Data Collection to open the Add Data Collection popup.

  3. Set name as desired, for example Facilities Heating - Natural Gas.

  4. Set Data Period to Yearly.

  5. Open the value help for Subject.

  6. Open the value help for the Source filter.

  7. Check Listed Substance.

  8. Choose OK.

  9. Enter Natural Gas in the Name field and choose Go.

  10. Select the first entry for Natural Gas and choose OK to confirm.

  11. Set Unit to Therm.

  12. Choose OK to create the data collection.




Create Calculation for Carbon Dioxide Equivalent



  1. Do the following actions on the edit compliance scenario screen for your new compliance scenario.

  2. In the Activities area, choose Add → Calculation to open the Add Calculation popup.

  3. Keep the default selection Equation from Compliance Requirement and choose OK.

  4. Set Calculation Name as desired, for example Facilities Heating - CO2e.
