Verification that builds trust

In an era of intense scrutiny, independent verification is no longer optional — it's the foundation of a credible climate strategy. We provide the robust, third-party assurance you need to report to your stakeholders with absolute confidence.

Turn reported data into a defensible asset

Making a public climate claim — from your annual carbon footprint to your Net Zero progress — is a high-stakes commitment. Investors, regulators (like the SEC and CSRD), customers and your own board are demanding data that is not just reported, but proven. Independent verification transforms your data from a self-assessment into a defensible, auditable asset.

Build investor confidence

Provide the robust, third-party validation that financial stakeholders require.

Meet regulatory demands

Ensure your reporting is compliant with evolving global standards.

Strengthen your brand

Protect your reputation by backing up every claim with undeniable, expert-vetted proof.

A tailored approach

We offer two levels of assurance, designed to meet your specific needs for reporting and risk management.

Limited Assurance

1. Data & Process Verification

Confidence that your data collection systems and processes are robust and reliable — the essential foundation for any credible reporting.

  • The goal: confidence that your data systems and processes are robust and reliable.
  • Best for: internal management reporting, and initial validation of your Carbon Neutral or Net Zero Standard claims.
Reasonable Assurance

2. Full-Scope Audit & Assurance

The highest level of defensibility for your public claims — the gold standard for organisations reporting to regulators or making major market announcements.

  • The goal: the highest level of defensibility for your public claims.
  • Best for: formal public disclosures, annual reports, compliance submissions (SECR, CSRD), and SBTi progress reporting.

Expertise meets technology

Any auditor can check a box. We provide a deeper level of insight.

  • Specialist expertise, not generalist auditing — we are not accountants who have learned about carbon; we are carbon experts who are also qualified auditors, with over 20 years of deep experience in GHG accounting and climate science.
  • Integrated with your technology — for clients using our Sustrax platform, our verification process is uniquely efficient, allowing for a faster, more insightful and more cost-effective assurance process.
