Independent Verification According to ISO 14064-3

‍

To conduct a recognized and comparable footprint analysis, both the data and methodology must meet formal quality standards.
The sustamize CO₂e database was validated by GUTcert GmbH according to the ISO 14064-3:2019-04 requirements — confirming that sustamize provides a verified CO₂ database aligned with international norms.

During the audit, the calculation methodology was checked for suitability, transparency, and plausibility, ensuring that emission factors and datasets are accurate and scientifically sound.

Why Verified CO₂e Data Matters

‍

Verified CO₂e data is critical for companies working toward reliable carbon transparency. An ISO-validated database allows organizations to:

• Ensure data consistency across Scope 1, 2, and 3 reporting
• Build trust and credibility in sustainability communication
• Align with CSRD, CBAM, and ISO standards
• Rely on GUTcert-certified carbon data for lifecycle and PCF calculations

Because sustamize combines verified data with automation tools such as Matcher, Interpreter, and Assembler, companies can calculate product and value-chain emissions faster, more accurately, and fully aligned with international standards.
