Verification, Validation & Assurance for Sustainability Disclosures
Independent third-party verification transforms your environmental data and sustainability disclosures from simple statements and claims into auditable, dependable evidence. Every engagement follows a consistent five-step, risk-based methodology.
Our Five-Step Methodology
Preliminary Evaluation
Initial readiness check, scope alignment, and boundary definitions of the sustainability disclosures.
Site/Remote Audit
Rigorous evidence gathering through either physical or remote audits of operations and primary data sources.
Evidence Review
Detailed verification of calculations, conversions, mass balance reconciliation, and follow-up on findings.
Assurance Statement
Drafting of the formal Assurance Statement and issuance of a management report outlining control improvement suggestions.
Technical Review
An independent verifier performs a final QA review before authorised signatories sign off on the official opinion.
First Time Auditing? For organisations reporting under a new standard, or stepping up from limited to reasonable assurance, we recommend performing a Pre-Assessment Gap Analysis against the reporting framework before starting the official audit timeline.
GHG Emissions Verification
Independent third-party verification of greenhouse gas statements at organisational and project level, providing trust and compliance for public claims and mandatory disclosures.
What We Verify
- Corporate GHG inventories (Scope 1, 2 and 3) prepared under ISO 14064-1 or the GHG Protocol
- Project-level emission reductions and removals under ISO 14064-2
- GHG statements supporting regulatory submissions, investor disclosures (CDP, SBTi) and voluntary claims
What You Receive
A formal Verification Statement with a limited or reasonable level of assurance, a detailed findings log, and a comprehensive management letter identifying data quality and control improvement opportunities.
Who it's for:
Organisations reporting under SECR, CSRD, meeting investor mandates, supporting SBTi validations, or publishing corporate sustainability reports.
