Data integrity
Are the source systems complete, consistent and reconciled to the underlying activity?
HomeAudit & Assurance
Independent assurance, built into the platform.
We don’t just help you collect carbon data — we prepare an audit-ready evidence trail that independent, third-party providers can verify and assure. Independent assurance partners review your numbers and sign an audit trail that stands up to external scrutiny.
What we validate
Assurance is more than a checkmark.
Independent assurance partners interrogate the things that make a carbon number defensible — the same dimensions an external auditor will test.
Methodology
Are organizational and operational boundaries drawn correctly across every entity?
Factor selection
Are the right emission factors applied, with appropriate sources and vintages?
Audit trail
Can every reported figure be traced back to its evidence, end to end?
Levels of assurance
Limited or reasonable — your call.
Regulations are moving from limited toward reasonable assurance over time. ESGARD, Quantisage’s ERP-native carbon platform, prepares your data for both, so you’re ready as the bar rises.
Limited assurance
A moderate level of confidence: the independent assurance provider finds nothing that suggests the data is materially misstated. It’s where most first-time reporters and current CBAM/SB-253 obligations begin.
- Risk-based review of methodology and data
- Negative-form conclusion
- Fastest route to a compliant filing
Reasonable assurance
A higher level of confidence with deeper testing and a positive opinion — increasingly required as disclosure rules mature. Same platform, expanded evidence and controls.
- Substantive testing and controls evaluation
- Positive-form opinion
- Future-proofs you for tightening regulation
The assurance process
Three steps, one platform.
Review & scope
We agree boundaries, materiality and the framework, then map your data against the assurance criteria.
Test & verify
Independent assurance partners test samples, check factors and trace figures to evidence — directly inside the ESGARD ledger.
Assure & report
You receive an independent assurance report and audit-ready evidence your independent assurance provider can rely on.
The assurance partner network

- An independent assurance partner network

Fifteen years verifying greenhouse-gas data — at S&P Global, PwC and Grant Thornton — taught me that trust is built in the audit trail. That’s what we engineer into ESGARD.
