GHG INVENTORY VERIFICATION
Independent verification of your corporate GHG inventory to strengthen credibility, support regulatory readiness, and enable confident climate decisions.
Build trust in your climate disclosures
Increase confidence in reported emissions and progress against targets with an independent verification aligned with leading standards.
Support informed business decisions
Ensure your inventory is robust enough to identify key emissions sources, prioritize reduction efforts, and support decarbonization planning.
Meet assurance requirements
Align with frameworks such as CSRD, SB253 (California), and Australia’s ASRS, and ensure your emissions data is ready for external verification.
Why verify your GHG inventory?
A corporate GHG inventory is the foundation for how organizations measure emissions across their operations, track progress against targets, and compare performance over time. It is no longer just a disclosure exercise. It informs decarbonization pathways and supports capital allocation decisions.
SustainCERT provides independent, criteria-based verification of your GHG inventory - confirming that it is prepared in line with recognized standards such as the GHG Protocol and ISO 14064-1 and can be trusted by stakeholders.
Respond to evolving disclosure requirements
Many organizations are now required - or preparing - to disclose and verify their emissions data under emerging frameworks such as:
- SB253 (California)
- Australia’s ASRS
- CDP disclosures
These frameworks increase scrutiny on reported emissions and introduce or anticipate third-party assurance requirements. GHG inventory verification helps ensure your data is aligned with recognized standards, defensible, and ready for external review.
What we verify
We verify your corporate GHG inventory (GHG statement) for a defined reporting period and scope, assessing whether it meets the requirements of the selected standards and whether it is credible and consistent.
This includes:
- Organizational and reporting boundaries (Scope 1, Scope 2, and relevant Scope 3)
- Methodologies, assumptions, and calculations
- Underlying data, controls, and supporting evidence
- Rather than re-performing calculations, we assess whether the inventory is traceable, consistent, and free from material misstatement.
Standards and criteria
Verification is conducted against globally recognized frameworks such as the GHG Protocol Corporate Standard, Corporate Value Chain (Scope 3) Standard, and Land Sector and Removals Standard, as well as ISO 14064-1.
All engagements follow ISO 14064-3 principles for the verification of GHG statements, ensuring a structured and consistent approach.
A risk-based verification approach
Our methodology follows ISO-aligned verification principles, with a clear emphasis on materiality and risk.
Each engagement begins with structured scoping to define boundaries, criteria, and inventory architecture. Verification then focuses on areas where discrepancies could materially impact reported results - prioritizing effort where it matters most.
This ensures efficiency without compromising rigor and reflects how verification is intended to function: as a risk-based assessment of material discrepancies.
What you receive
Each engagement delivers a clear, documented verification outcome aligned with your selected scope and criteria.
- Independent verification statement (limited or reasonable assurance)
- Structured assessment against applicable standards
- Transparent documentation of verification activities and findings
- Clear identification of discrepancies and improvement areas
- Outputs are designed for both external disclosure and internal governance.
Digitally enabled verification
Corporate GHG inventories are complex and often difficult to audit consistently.
Our verification services are supported by our Carbon Verification Platform, designed to structure data, streamline evidence handling, and improve traceability across the verification process.
This allows you to:
- Reduce manual effort in data and evidence collection
- Improve traceability and auditability across systems
- Ensure consistency across reporting cycles
