Australian Environmental Certificate Position, Liability and Registry Records (LGC / STC / ACCU)

An organisation's own environmental certificate records under the Renewable Energy Target and the carbon crediting schemes: LGC and STC position and liability reports (holdings against the surrender obligation set by the renewable power percentage or small-scale technology percentage), REC Registry transaction, transfer and surrender records, certificate inventory against forecast creation or surrender, and ACCU / Safeguard Mechanism credit holdings. Held by generators, retailers, gentailers and other liable entities. Public material (CER Quarterly Carbon Market Report, the REC Registry public register, the published list of accredited power stations, media releases and annual reports) is excluded.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium. Certificate type, status and action vocabulary comes from the CER REC Registry API specification, and the accreditation code format was derived from the CER's published accredited power station list (3,432 codes, three shapes, 16 fuel prefixes, eight state codes). Accreditation codes are public register values, so they only corroborate. No public source confirms a format for certificate serial numbers (the API types them as bare integers), small-scale unit identifiers or ACCU / ANREU unit and project identifiers, so none of these is matched: STC and ACCU records rely on vocabulary and quantity structure only. 85/75 are heuristic evidence tiers, not measured accuracy.

Should match

LGC position and liability - compliance year 2026 (internal) Opening holdings: 412,500 LGCs Required surrender (RPP 18.96%): 655,000 LGCs Forward purchases contracted: 150,000 LGCs, counterparty Example Wind Pty Ltd Shortfall to cover: 92,500 LGCs — Position and liability report with several quantities, RPP and forward purchases - intended 85
STC liability forecast Q3-27: estimated 1,240,000 STCs at the published STP; clearing house exposure under review. — STC liability forecast with one quantity, no identifier - intended 75
REC Registry transfer offer: 25,000 LGCs from accreditation code SRPYAC98, vintage 2025, status Pending transfer. — Registry transfer record with quantity, accreditation code and status - intended 75 (one quantity only)
ACCU holdings register ANREU account balance: 48,200 ACCUs (vintage 2024-25) Safeguard surrender planned: 30,000 ACCUs — ACCU holdings with two quantities and vintage - intended 85
Certificate inventory vs forecast creation: WD00SA98 Q1 LGCs created 8,410; Q2 LGCs forecast 11,250; registered person to confirm. — Inventory against forecast with accreditation code and two type-then-number rows - intended 85

Should not match

Quarterly Carbon Market Report - March 2026: about 9.1 million large-scale generation certificates were surrendered for the 2025 compliance year. — CER Quarterly Carbon Market Report (public)
Historical accredited power stations: SRPYAC98 Example Solar Farm - Solar - ACT - baseline 0 MWh; WD00SA98 Example Wind Farm - Wind - SA. — Public accredited power station list (accreditation codes are public register values)
LGC position template Opening holdings: [number] LGCs Required surrender: [number] Use this template for the quarterly report. — Blank position template
Attach the certificate of currency to the contract register before the transfer is approved. — Generic certificate / register wording without environmental certificate vocabulary
Training certificate register: 42 certificates issued, 3 pending renewal. Share certificate transfer of 1,000 certificates approved. — Training and share certificate registers with counts but no LGC / STC / ACCU unit (65 discovery at most)

Known false positives

CER Quarterly Carbon Market Report, the REC Registry public register and its API, and the published list of accredited power stations quote certificate volumes and accreditation codes. Mitigation: Public-source terms are excluded within the proximity window at every tier, and accreditation codes never enforce on their own.
Generic "certificate register" or "certificate transfer" wording (shares, insurance, training). Mitigation: Enforce tiers need a certificate quantity in LGCs / STCs / ACCUs / SMCs (a bare "N certificates" does not count), or an accreditation code with an independent registry or liability term.
Year-like numbers before a certificate type (for example "2026 LGCs" meaning vintage). Mitigation: Four-digit bare numbers are not counted as quantities; comma-grouped, 1-3 digit and 5-7 digit numbers are.
