As stakeholder expectations around ESG transparency continue to rise, organizations (particularly as part of a supply chain) are under increasing pressure to disclose credible, high-quality sustainability data. Investors, regulators, customers, and communities alike are demanding accountability and CDP disclosures are a key part of that equation. 

With the 2025 CDP disclosure window now open and the scoring deadline fast approaching on 15 September 2025, the time to act is now. As a CDP Silver Accredited Solutions Provider, ERM CVS is ready to support your organization in strengthening the credibility of your disclosures through third-party independent assurance while providing technical expertise resulting in a resource-conscious approach. Achieving a strong CDP score signals robust environmental performance, bringing confidence to investors, customers, and regulators, while unlocking long-term value. 

Why Assurance Matters for CDP and ESG Reporting 

Assurance is more than a compliance checkbox—it’s a strategic tool that: 

  • Enhances credibility with investors, regulators, and other stakeholders 
  • Improves CDP scores by demonstrating transparency and data integrity, further enhancing credibility 
  • Reduces risk of material misstatements in public disclosures 
  • Drives internal improvements in data quality and reporting processes 

CDP explicitly recognizes third-party verification to boost scores, particularly in areas like emissions data and climate governance. Assurance signals to CDP, and your stakeholders, that your disclosures are trustworthy and robust.
