Straight answers on ESG assurance
Start with the questions reporters ask most about independent assurance, then bring us the disclosures you want assured.
Assurance refers to independent verification of sustainability or emissions-related data and claims, to give stakeholders confidence in their accuracy.
It builds credibility with investors, regulators, and customers by confirming that reported data and claims are reliable.
Commonly assured disclosures include greenhouse gas inventories, ESG reports, and sustainability performance claims, though scope should be defined per engagement.
The two are related but not identical. Assurance typically focuses on verifying specific claims or data sets, while audits can be broader; exact distinctions depend on the framework being used, which should be confirmed with the provider.
This is generally tied to reporting cycles (e.g., annual sustainability reports), but frequency should be agreed upon based on organizational and regulatory requirements.
Assurance is independent, third-party checking of reported information. For example verification of emission reductions for carbon credits, or assurance of ESG data such as BRSR Core indicators. It is required by many standards and regulations and builds trust with buyers, investors and regulators.
Validation is the up-front, independent check that a project's design meets the chosen standard before it starts; verification is the later, periodic check that the claimed emission reductions or removals actually occurred, based on monitoring data. Both are carried out by accredited independent bodies.
