C2C certificate for WICONA

Certificate based on a circular approach

The C2C product certification is both a design concept and a reference which is becoming widely established, especially in the European markets. The C2C certificate brings added value and is an alternative to the traditional construction certificates (DGNB, LEED, BREAM, etc.), its criteria directly concern the product and not the building itself. The emphasis is then on the manufacturer’s responsibility and also implies that of his entire prefabrication chain and his suppliers.



5 criteria

To obtain this certification a product must meet the minimum requirements defined by one of the 5 target levels in all five of the following categories:

  • Materials
  • Material cycle
  • Renewable energies and climate
  • Water
  • Social responsibility
