From estimation to verification: Why carbon savings need independent validation
If you're claiming carbon savings from energy efficiency upgrades, process changes, or clean tech investments – then you must be ready to prove it.

With AASB S2 climate reporting about to become mandatory, many Australian businesses are about to discover that their climate claims will face the same level of scrutiny as their financial data.
What does this mean in practice?
If you’re claiming carbon savings from energy efficiency upgrades, process changes, or clean tech investments – and those claims support your transition plans, net zero targets, or emissions reductions – then you must be ready to prove it.
Under AASB S2, companies will need to provide assured disclosures, starting with Limited Assurance and stepping up to Reasonable Assurance within a few years. That means your climate data must be:
- Verifiable
- Traceable
- Aligned with accepted methodologies
- Supported by credible, independent assessment
This is not something most internal teams or solution providers are equipped to do alone. That’s where a neutral third party like C6 ESG comes in. We help organisations:
- Independently verify carbon savings
- Apply audit-ready methodologies
- Prepare systems for future assurance requirements
- Build investor and regulator confidence
Climate disclosure is no longer just a communications exercise – it’s an audit exercise. If you’re serious about credible climate reporting, don’t wait until Reasonable Assurance becomes mandatory. Get in touch to discuss how we can help you prepare your carbon savings data for assurance.
