❔Unit type code
Intro
SAFcA and SAFcE both share a similar unit type code that indicate their characteristics. Unit type codes are always accompanied by an explanatory tooltip.
The unit type code follows this formula AAAAA-BC-D, where:
A is either 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" SAFcA. If these elements change for the underlying parent, then they will also change for the SAFcE.
📄 Sustainability tier
“A” indicates a SABA-preferred SAFcA (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 SAFcA (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 SAFcA (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 SAFcA and SAFcE use a similar numbering scheme, they have different meaning.
Usability tiers for SAFcA
“1” indicates a SAFcA that is applicable only for compliance use by air transport providers.
“2” indicates a SAFcA that can be retired for voluntary purpose but from which no SAFcE has been unbundled.
“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.
