PCF: Fossil aviation emissions in the TfS standard

In accordance with the TfS standard, fossil aviation emissions must be reported in the PCF report. They have therefore been added as an additional emission factor when creating an activity.

When an ecoinvent factor is applied, the field is filled in automatically. When creating an individual activity, you can optionally complete the data field yourself.

In the footprint, the GWP fossil aviation emissions are reported as the sum across all activities.
