Scope 3.4 and Scope 3.9: Calculate Transport Emissions Automatically

Use the automated transport calculation to record upstream and downstream transport emissions based on your transport data. The tool determines a route from the information you provide and calculates the associated emissions.

Create an automated transport activity

1. Open the relevant organisational unit and select Scope 3.

2. Click Add activity, assign the activity to Scope 3.4 or Scope 3.9, and select Automatic.
   

3. Enter the activity details and transport details.
   

4. Let the tool determine the transport legs automatically or add them manually.
   

5. Start the calculation, review the result, and save the activity.
   

Required information

Provide locations as precisely as possible. Depending on the input field, you can use a city, site, or location code.

Define transport legs

With automatic routing, the tool uses the Origin and Destination to determine a representative distance and estimate likely transport modes for the individual legs.

If the actual route is known, you can map the legs manually, for example:

1. Supplier site to port by road

2. Port to port by sea freight

3. Port to warehouse by road

Manual leg input is particularly useful when you have reliable logistics data from suppliers or freight providers.

Detailed example: Sea freight in Scope 3.4

A company imports electronic components from a supplier in China to its warehouse in Hamburg. The shipment is handled by an external logistics provider and is therefore recorded in Scope 3.4.

After starting the calculation, the tool determines the emissions for the transport set-up provided. Then review the weight, unit, temperature control, Origin, Destination, and calculated transport legs.

Review the result and source path

Once calculated, review the following before saving:

• Scope 3.4 or Scope 3.9 assignment;
• activity title and description;
• weight and unit;
• container, TEU, and temperature-control information;
• Origin, Destination, and transport legs;
• calculated emissions;
• the source path, where provided for the activity.

When should I use automation?

Use automation when you know the goods quantity and the Origin and Destination, but do not have complete information about the actual route or emission factor.

Create the activity manually when you need to use an exact route, a specific emission factor, or detailed data from your logistics provider.

Important: Automatically calculated routes and emissions are estimates based on the information entered. They provide a fast calculation, but give you less control over the underlying calculation logic.
