ISO 14064 is the internationally recognized standard for quantifying and reporting greenhouse gas (GHG) emissions and removals. Whether you’re developing an emissions inventory, verifying reductions, or preparing for carbon trading, ISO 14064 provides the framework to ensure your data is credible, consistent, and transparent.
 
Our team helps you navigate the complexities of Parts 1, 2, and 3—covering organizational-level reporting, project-level quantification, and independent validation. With our support, you’ll be equipped to meet regulatory requirements, enhance stakeholder trust, and align with global climate goals.

In a world of increasing climate scrutiny, third party verification is no longer optional—it’s essential. Independent assurance adds credibility to your environmental claims, strengthens investor confidence, and ensures compliance with voluntary and mandatory reporting frameworks.
 
We provide impartial verification services for GHG inventories, sustainability disclosures, and carbon offset projects. Our approach is rigorous yet collaborative, helping you identify gaps, improve data quality, and meet the assurance standards of ISO 14064-3, ISAE 3000, and other leading protocols.
