    Methodology and Integrity

    Carbon3 is designed to support audit-ready tracking of inset credits linked to verified Scope 3 emissions reductions.

    This page summarises our approach at a high level. Requirements and outputs vary by project type, methodology, and verification pathway.

    What an Inset Credit Represents

    An inset credit represents a quantified emissions reduction or removal, measured in tCO₂e, that occurs within a value chain and is supported by project evidence and independent verification. Each inset credit:

    • Is tied to a specific project activity, time period, and system boundary within a defined value chain.

    • Is a benefit that may be transferred or allocated prior to retirement.

    • May qualify for Scope 3 emissions reduction, depending on the party retiring the credit.

    What Carbon3 Does and Does Not Do

    Carbon3 is designed to:

    • Track issuance, transfers, and retirement records

    • Support allocation of benefits among credit holders

    • Provide audit-ready reporting outputs

    Carbon3 is not designed to:

    • Replace corporate carbon accounting judgement

    • Guarantee acceptance by any specific standard or regulator

    • Substitute for independent validation or verification

    Integrity, by Design

    Independent verification

    Projects require independent, third-party validation and verification before credits are issued.

    Allocation-aware accounting

    Credits can be allocated among participants to support benefit sharing while reducing double counting risk.

    Traceable provenance

    Each credit maintains a record trail from verified project activity through issuance, transfers, and retirement.

    Lifecycle and Recordkeeping

    Carbon3 maintains a structured record trail across the credit lifecycle.

    Illustrative lifecycle, requirements vary.

    Record Trail

    • Project evidence

    • Validation report

    • Verification report

    • Issuance record

    • Transfer + Sale records

    • Retirement certificate

    Record Structure

    • Evidence pack: Project documentation, monitoring data, boundary and assumptions.

    • Issuance record: Vintage, tCO₂e quantity, verification reference, identifiers.

    • Transfer and retirement records: Position changes, allocations, retirement certificate.

    Platform Activity Outputs

    Participants receive standardised outputs intended to support internal review and external assurance.

    Common assurance questions

    Carbon3 maintains unit-level records with defined ownership, allocation, and retirement states to support traceability. Double-claim risk is mitigated through controlled issuance, explicit allocation rules, and permanent retirement records, subject to applicable accounting and reporting frameworks.

    Projects are subject to independent third-party verification in accordance with the applicable methodology. Verification bodies, scope, and procedures vary by sector, jurisdiction, and reporting requirements.

    Carbon3 is designed to be compatible with commonly used corporate greenhouse gas accounting, assurance, and audit frameworks, including those applicable to Scope 3 emissions. Alignment and claim eligibility depend on project design, verification outcomes, and the reporting context of the end user.

    Carbon3 supports the transfer of units prior to retirement, with records intended to preserve traceability across ownership changes. Transferability does not alter the underlying verification status or the requirements governing use or disclosure of claims.
