TCO Certified includes comprehensive criteria covering four key sustainability areas: climate, substances, circularity, and supply chain.

The criteria address environmental and social risks throughout the product life cycle, from raw material extraction to end-of-life. They are designed to reduce climate impact, ensure safer substances, support longer product lives and circular flows of products and materials, and improve working conditions further up the supply chain.

All criteria are mandatory, and products must meet all criteria in their category to be certified according to TCO Certified. Compliance is independently verified both before and throughout the life of the certificate to ensure that the criteria are met over time.

Examples of what the criteria cover:

  • Climate — reducing greenhouse gas emissions across the product life cycle.
  • Substances — ensuring safer substance use in products and manufacturing.
  • Circularity — extending product lifespans and supporting circular flows of products and materials.
  • Supply chain — improving working conditions and reducing social and environmental risks.
