Why labels might be missing
The labels you see depend on your selected calculation method. Different methods support different emission factor databases.
For transport emissions
Distance-based calculation method:
Only supports vehicle types where full emission volume applies to one trip
Examples: car, van, motorcycle
Not supported: plane, train, bus (use distance-weight or distance-passenger methods instead)
Distance-weight or distance-passenger methods:
Required for shared transport: planes, trains, buses
Allows accurate allocation of emissions per passenger or weight
For waste emissions
Quantity-based method:
Uses UK Government emission factor database
Different waste types and treatment options available
Spend-based method:
Uses Exiobase emission factor database
Different label options than quantity-based
How to request different emission factors
If the label you need isn't available, Data Importer uses a subset of our full emission factor database.
To request a different emission factor to be applied:
Label your data with “Unknown”
Use Ask Your Advisor
Select “Request reports or additional calculations”
Request change of emission factor selection
