Overview

GRI Assurance and Reporting Integrity

The Global Reporting Initiative (GRI) Standards provide a widely used framework for communicating ESG performance in a consistent and comparable way.

Frequently Asked Questions

Your GRI assurance questions—answered

GRI assurance is an independent assessment of selected disclosures in a GRI‑based sustainability or integrated report to determine whether they are prepared in line with relevant GRI Standards and free from material misstatement.​​

GRI encourages organisations to obtain external assurance and disclose its scope and conclusions, but it does not make assurance compulsory; requirements may instead come from regulators, stock exchanges, or investors.​

Engagements usually focus on material topics, key performance indicators, data collection processes, internal controls, and alignment with GRI reporting principles such as accuracy, balance, and completeness.​​

Limited assurance relies mainly on analytical procedures and inquiries to provide moderate assurance, while reasonable assurance involves more detailed testing and offers a higher level of confidence in the reported information.​​

Assurance improves data quality, reveals gaps and risks, and strengthens the credibility of disclosures used by boards, investors, and lenders, helping to align ESG targets and actions with reliable information.​​
