1. What is Sustainability Assurance Under CSRD?

Companies must obtain limited assurance on their sustainability reports, meaning external auditors will verify the accuracy and completeness of ESG disclosures.

2. Who Conducts the Assurance?

The same auditor who performs the financial audit can provide sustainability assurance or

A separate accredited sustainability assurance provider can conduct the verification.

Assurance providers must follow EU-approved assurance standards to ensure uniformity and reliability.

3. Key Areas Subject to Assurance

Auditors will verify:

Compliance with ESRS (European Sustainability Reporting Standards)

Double Materiality Assessments (both financial and impact materiality)

Accuracy and consistency of ESG data and disclosures

Alignment with sustainability risks, strategies, and business performance

4. How Can Companies Prepare?
