Zadig&Voltaire's goal is for 100% of its key raw materials to be supplied from certified sustainable sources by 2025.  To this end, the brand uses:

- Cotton certified as compliant with the GOTS (Global Organic Textile Standard) or the OCS (Organic Content Standard) for the manufacture of its products.

- Pure new wool certified as compliant with the RWS (Responsible Wool Standard).

- Virgin cashmere from sources certified as compliant with the Good Cashmere Standard.

- Materials, such as polyester or cashmere, made from GRS-certified recycled fibres (Global Recycled Standard).

- Viscose made from fibres certified as derived from sustainably managed forests or Ecovero®, which guarantees the use of fibres both traced and certified as derived from sustainably managed forests.

- Leather from tanneries certified by the LWG (Leather Working Group).
