Understanding the Activity Source
An Activity Source uniquely identifies the source responsible for emissions resulting from energy consumption or production within an activity. It is defined as a combination of the activity type and its determinants such as fuel type, vehicle type, energy type, or other relevant characteristics, which allow for the selection of the appropriate emission factor for accurate emissions calculations. For example, in Stationary Combustion activities under Scope 1, the primary determinant is usually the fuel type. If an organization uses diesel, natural gas, coal, and LPG for such stationary combustion activities, they should consider creating a separate activity source for each of these fuels. Similarly, in Purchased Energy activities for Scope 2, the primary determinants are usually energy type and grid region. When a sustainability transaction is created with an activity source, it ensures that the correct emission factor is identified and it can be applied during emissions calculation using a third-party solution, leading to precise emissions reporting.
You use the Activity Source program (P20S07) to create and manage activity sources. When you specify the activity type for an activity source in this application, the system automatically loads the determinant types associated with the activity type, enabling you to select the appropriate determinant. The system stores the Activity Source details in the Activity Source Header (F20S07) and Activity Source Detail (F20S08) tables. When you enter the activity source in the sustainability transaction, it retrieves the corresponding activity type and determinant details associated with that activity source.
