Sustainability Report Assurance

Independent third-party verification ensures that your ESG disclosures are credible, accurate, and aligned with global sustainability frameworks.

As expectations for ESG transparency grow, verified sustainability reporting is becoming essential. A third-party assured report helps demonstrate that your organization is managing its most material environmental, social, and governance (ESG) issues with integrity.

Often included alongside financial reporting, sustainability disclosures are increasingly scrutinised by investors, regulators, and partners. Independent assurance provides credibility, supports compliance, and builds stakeholder trust.

At DNV, we offer a spectrum of assurance services — from data verification to deeper reviews that assess how your reporting aligns with stakeholder expectations and integrates into your broader strategy.

 

Why Sustainability Report Assurance is important

Assuring your sustainability reporting provides significant advantages, including:

• Enhancing stakeholder trust – Independent assurance strengthens credibility and transparency in your sustainability disclosures.
• Reducing ESG risks and identifying opportunities – A structured review helps you refine your sustainability strategy and highlight areas for improvement.
• Attracting responsible investors – A robust sustainability compliance framework signals commitment to long-term ESG goals, making your business more appealing to investors.
• Improving internal alignment & engagement – Assurance fosters greater awareness, enthusiasm, and accountability across your organization, ensuring ESG goals are met.
  
  

By obtaining sustainability report verification, companies improve their reputation, comply with evolving regulatory standards, and drive long-term value creation.
