TCO Certified and its robust system of accountability helps purchasers directly influence the IT industry. The resources, industry connections and experience needed to verify and improve the IT supply chain is embedded in each certified product. Each year, approximately 20,000 hours are spent verifying claims specifically connected to the certified products that purchasers request.

This text is part of our latest report, Impacts and Insights: Navigating the Sustainable IT Revolution – The critical role of independent verification. The report helps buyers worldwide accurately verify social and environmental aspects of their purchases.


So how does it all work? Before an IT product is certified, a global team of accredited experts verifies environmental and social aspects in factories and products, as well as the product’s performance. Verifiers are specialized in specific areas, such as toxicology, environmental assessments, supply chain social responsibility, visual ergonomics, and product safety.

No individual party should be able to claim that a product meets all requirements. Therefore, before issuing a certificate for any IT product, TCO Certified requires sign-off from two parties: an independent, accredited verification organization that signs a verification of compliance report (VOC), and the certification body (TCO Development).
