Assurance & Standards

Audit-Grade Credibility Built for Institutional Use

Theaus CH₄ methane-abatement credits are designed to meet the expectations of institutional investors, auditors, regulators, and corporate disclosure frameworks. Our assurance architecture prioritizes independence, transparency, and alignment with internationally recognized standards to ensure long-term credibility and defensibility.

ISO 14064-Aligned Methodology

All projects are developed, implemented, and assessed in accordance with internationally recognized greenhouse gas accounting standards, including:

ISO 14064-2 — Specification for the quantification, monitoring, and reporting of greenhouse gas emission reductions
ISO 14064-3 — Specification for the validation and verification of greenhouse gas assertions

These standards govern project boundary definition, baseline determination, conservative quantification, monitoring protocols, and documentation requirements. Alignment with ISO ensures that measured outcomes are suitable for audit review, disclosure, and long-term reliance.

Independent, Accredited Validation & Verification

Methane-abatement outcomes are validated and verified by independent, accredited third-party Validation and Verification Bodies (VVBs) with demonstrated competence in oil and gas methane measurement and carbon accounting.

VVBs operate independently from project developers and asset owners and provide:

Review of project design and eligibility
Verification of measured methane reductions
Confirmation of conformance with applicable ISO standards

This independence is fundamental to credit integrity and institutional trust.

Standards-Body–Aligned Best Practices

Theaus CH₄ applies assurance principles consistent with internationally recognized best practices for high-quality carbon instruments, including those referenced by leading ICROA/ICVCM standards bodies and institutional buyer frameworks.

These principles emphasize:

Environmental integrity and additionality
Robust monitoring, reporting, and verification (MRV)
Transparency, conservatism, and traceability
Protection against double counting and double claiming

This alignment ensures methane-abatement credits are suitable for corporate climate strategies and financial scrutiny.

Clear Carbon Title & Chain of Custody

Each methane-abatement credit is:

Serialized and uniquely identifiable
Issued with a documented chain of custody
Structured to prevent double issuance or double claiming

Carbon rights, project ownership, and issuance pathways are contractually defined to support defensible title and balance-sheet treatment.
