ISO 14067: the carbon footprint of products
ISO 14067 is the international reference standard for calculating a product's carbon footprint (Product Carbon Footprint). It is based on life-cycle assessment and ensures comparable, credible results.
The life-cycle principle
The standard assesses emissions across the entire life cycle: raw-material extraction, manufacturing, transport, use and end of life. This “cradle-to-grave” approach avoids shifting impacts from one stage to another and offers a complete view.
Primary data and emission factors
The reliability of an ISO 14067 calculation depends on data quality. Primary data (measured at the supplier) is the most reliable; otherwise, emission factors from recognised databases such as ADEME's Base Empreinte® are used. UltraCarbon leverages suppliers' certified data to maximise accuracy.
Certifying and proving a product footprint
Beyond the calculation, you need to be able to prove the result. UltraCarbon issues tamper-proof certificates: SHA-256 hash, tamper-proof audit log and a verifiable cryptographic seal (Ed25519 signature), all publicly verifiable via a URL. This is a trust asset towards customers, principals and regulators.
Frequently asked questions
Is ISO 14067 mandatory?
No, it is a voluntary standard. But it is becoming a de facto standard for meeting customer requirements, tenders and future environmental-labelling regulations.
How does it differ from an LCA?
Life-cycle assessment (LCA) covers several environmental impacts (water, resources, toxicity, etc.). ISO 14067 focuses on the climate (carbon) impact and relies on the same methodological principles as LCA.
