❔Unit type code

Intro

SAFc, SAFcA, and SAFcE are the three type SAF Certificates that can be identified and understood by their "unit type code". Unit type codes are always accompanied by an explanatory tooltip.

3 example unit type codes

The unit type code follows this formula AAAAA-BC-D, where:

• A is either SAFc, SAFcA, or SAFcE

• B is the sustainability tier

• C is the usability tier

• D is the assurance level

SAFcE inherit their unit type code elements B and D from their "parent" SAFc. If these elements change for the underlying parent, then they will also change for the SAFcE.

📄 Sustainability tier

• “A” indicates a SABA-preferred SAFc (that is, the unit represents SAF that meets the criteria for SABA-preferred SAF according to the SABA SAF Sustainability Framework).

• “B” indicates a SABA-eligible SAFc (that is, the unit represents SAF that meets the criteria for SABA-eligible SAF according to the SABA SAF Sustainability Framework).

• “C” indicates an SCS-eligible SAFc (that is, the unit represents SAF that meets the minimum criteria of a SAF sustainability certification scheme).

The sustainability tier of a SAFc may be updated by the Registry Administrator if the underlying issuance information is changed in accordance with the registry rulebook.

🪃 Usability tier

Though the usability tiers for SAFc, SAFcA, and SAFcE use a similar numbering scheme, they have different meaning.

Usability tiers for SAFc

SAFc can only be "Type 2". SAFc was formally called SAFcA Type 2, but was renamed for clarity.

SAFc can be retired for voluntary purpose and contain both SAFcA (Scope 1) and SAFcE (Scope 3) certificates that are yet to be unbundled from one-another.

Usability tiers for SAFcA

• “1” indicates a SAFcA that is applicable only for compliance use by air transport providers.

• “3” indicates a SAFcA that is available for voluntary purpose retirement and a SAFcE was already unbundled from it.

The registry automatically converts usability tier 2 SAFcA to usability tier 3 when SAFcE are unbundled from the SAFcA

Usability tiers for SAFcE

• "2" indicates the SAFcE cannot yet be retired because the underlying SAFcA has not been retired.

• "3" indicates the SAFcE can be retired because the underlying SAFcA has been retired.

The registry automatically converts usability tier 2 SAFcE to usability tier 3 when the underlying SAFcA is retired.

👍 Assurance level

The assurance level is a classification system in the registry that indicates the degree of verification of the sustainability information associated with a SAFc. The assurance levels are explained in the registry rulebook and summarised below:

• “VAL” indicates that a SAFc has been validated.

• “REV” indicates that a SAFc has been revalidated.

• “VER” indicates that a SAFc has been verified.

• “UR” indicates that the assurance level of a SAFc is under review.
