Can SAF certificates (book and claim) reduce my Scope 3 business travel or air freight emissions?
Not inside your GHG Protocol inventory today. The Scope 3 Standard has no market-based method, so Category 6 travel and Category 4 or 9 air freight stay at their activity-based figure. You can report SAF certificate claims separately, next to the inventory, with full certificate details. Rules are under revision.
What a book and claim certificate is
Sustainable aviation fuel is blended into the fuel supply at some airport, usually not on your flight. The supplier issues a certificate for the lifecycle emission reduction of that fuel, and you buy the claim. A registry tracks the certificate so the same reduction is claimed once. The Roundtable on Sustainable Biomaterials Book and Claim Manual sets out one such system.
How to report it now
- Report Category 6 business travel and Category 4 or 9 air freight in full, from distance or spend as usual.
- Show the SAF claim on a separate line outside the Scope 3 total, labelled as a certificate-based claim.
- State the fuel volume, feedstock, lifecycle reduction per tonne, the registry, the certificate IDs and the retirement date.
- Say whether the airline or forwarder also counts the same SAF, for example under an aviation scheme, so a reader can see any overlap.
Decision rule
- If you need a number to fit an SBTi or buyer target: do not subtract it yet; check the target-setter's current rules first.
- If you want to show action to customers: buy certificates from a tracked registry, retire them in your name, and disclose separately.
- If the forwarder offers a lower emission figure on the invoice because of SAF: ask for the certificate behind it before using it.
Where the rules are heading
The GHG Protocol is reviewing market instruments in Scope 3, and the SBTi draft Corporate Net-Zero Standard version 2 discusses limited use of environmental attribute certificates. For freight, the Smart Freight Centre's market-based accounting guidance for logistics already describes how such claims can be reported beside the inventory. None of these yet changes the Scope 3 Standard.
Example: how the report looks
- Category 6 business travel, distance-based: 200 t CO2e
- SAF certificates bought and retired: stated lifecycle reduction 15 t CO2e
- Scope 3 Category 6 reported: 200 t CO2e (unchanged)
- Separate disclosure: SAF certificate claim of 15 t CO2e, with registry and certificate IDs
Figures are illustrative. If a future method allows the deduction, the same records would support 200 minus 15 = 185 t CO2e.
What Senseible does here
Senseible keeps your travel and freight invoices together with the SAF certificate and retirement documents, so the activity-based Scope 3 lines and the separate certificate claim rest on one evidence file.
