Individual Value Input: Record Component Values Within an Emission Activity

With Individual Value Input, you can document several component values within one emission activity. This is especially useful when an emission factor uses a combined unit of measurement, such as weight × distance or passengers × distance.

Instead of entering one pre-calculated total, you record the individual components directly in the tool.

When should I use Individual Value Input?

Use this feature when:

• several transport legs use the same emission factor;

• weight and distance are available separately;

• you want to document several component values within one activity;

• the underlying data should remain easy to review.

To use the feature, select an emission factor with a combined unit of measurement, such as tonne-kilometres, container × kilometres, or passenger × kilometres.

How to record component values

1. Create or open the relevant emission activity.
   

2. Select an emission factor with a combined unit of measurement.
   

3. Enable Individual Value Input.
   

4. Name the first component value, for example “Route 1”.

5. Enter the relevant values, such as weight and distance.
   

6. Select Add Component Value to add further component values.
   

7. Save the activity.

Important: The same emission factor is used for all component values within an activity.

Example: transport with several legs

A train shipment from Dresden to Italy consists of several legs. Instead of calculating all tonne-kilometres in advance, record each leg separately:

This makes the composition of the total value transparent. The approach follows the established distance-based calculation method for transport emissions: mass × distance × the applicable emission factor. GHG Protocol: Scope 3 Calculation Guidance

Further use cases

• Hotel stays: Record the number of participants and overnight stays for each event day.

• Business travel: Record several legs of a journey where the same emission factor applies.

• Goods transport: Document separately which quantities were transported over which distances.

Individual Value Input or Grouping?

If transport modes, emission factors, or calculation bases differ, create separate activities and group them where useful.

For more information on Grouping, see Grouping Emission Activities Within a Scope.

Tip for reliable results: 
Make sure that the activity data and emission factor match. For example, an emission factor in kg CO₂e per tonne-kilometre requires information on both transported quantity and distance. Individual Value Input makes the underlying data transparent, but the quality of the result still depends on using accurate data and the appropriate emission factor.
