For Zadig&Voltaire, playing a role in combating climate change and preserving biodiversity means prioritising changes to the materials it uses and its products as they represent more than 90% of the brand’s impact!Its collections are dependent on the services provided by nature. Zadig&Voltaire believes it is essential for it to protect resources, biodiversity and ecosystems, so that it can continue to create.To this end, Zadig&Voltaire’s strategy focuses on the following:• Strict compliance with international recommendations, which means using raw materials of plant and animal origin which respect recommendations published by the CITES and the International Union for Conservation of Nature (IUCN) red list. The brand does not use any fur or exotic hides in its collections.• Making use of certified key raw materials a brand standard• Developing circularity of materials• Rolling out a certification approach for the entire supply chain when it is possible and relevant• Ensuring animal welfare in our supply channels, a commitment formalised in the Zadig&Voltaire Animal Welfare Charter• Promoting processes with a reduced environmental impact• Aligning the product manufacturing processes with the most rigorous standards regarding chemicals• Ensuring our packaging can be recycled
Our ambitions• 100% of key raw materials certified sustainable or with a reduced environmental impact• Zero virgin plastic made from fossil fuels• 100% of our packaging made from certified sustainable, biobased or recycled and recyclable materials.• 100% traced products
Committing to sustainable key raw materials:
CashmereThe vast majority of the virgin cashmere used by the brand comes from Inner Mongolia. In order to support sustainable cashmere production, Zadig&Voltaire joined the GCS and set itself the goal of using 100% certified cashmere in all its collections. In order to promote the circular economy dynamic, we are also developing styles made from certified recycled fibres and working on accelerating this programme in our cashmere collections. At the end of 2025, 99% of the cashmere used for Zadig&Voltaire collections is made with GCS certified or recycled cashmere.
WoolWool is also an important material for the brand, which offers many of its iconic styles in sheep’s wool. Zadig&Voltaire’s goal is to use 100% wool from RWS-certified channels guaranteeing animal welfare, traceability and sustainable management of grazing land. At the end of 2025, 98% of the wool used to make Zadig&Voltaire collections is RWS certified or made from certified recycled fibres.
CottonZadig&Voltaire is committed to using 100% certified organic cotton. This means cotton grown without pesticides, insecticides or chemical fertilisers, and without GMOs. At the end of 2025, nearly 90% of the cotton used in the brand's ready-to-wear collections was made from organically-grown fibres. Furthermore, 100% of jersey and denim styles are made with certified organic cotton fibres.
LeatherLeather is also one of the materials that are part of the brand’s DNA. In order to support more sustainable leather production, Zadig&Voltaire has committed by 2025 to only sourcing leather from certified Leather Working Group (LWG) tanneries, an organisation of which the brand is also a member. The LWG is an organisation composed of brands, suppliers, leather manufacturers and other stakeholders from the leather industry. It has developed a programme of audits that certify leather production sites based on their environmental performance level. Since 2022, 100% of leather used for the Zadig&Voltaire ready-to-wear and accessory collections has come from LWG-certified tanneries.
PolyesterPolyester is a by-product of oil and is non-biodegradable. That is why we are working on using recycled polyester for our ready-to-wear and accessory collections from 2022 onwards. We want to use 100% recycled polyester by 2025. With this in mind, our iconic Japanese satin is now made from 60% recycled fibres.
ViscoseUsing viscose made from fibres certified as coming from sustainably-managed forests is part of Zadig&Voltaire’s standards and requirements. The majority of the viscose used by the brand is EcoVero®, which also guarantees the implementation of particularly rigorous environmental practices during the manufacturing phase of the material. This reduces the brand’s impact in terms of CO2 emissions and energy and water consumption. At the end of 2025, 80% of the viscose used in the collection was made from certified fibres sourced from sustainably managed forests.
Zadig&Voltaire works hard to continually offer its customers increased transparency, share the know-how developed with its partners in various countries and allow customers to identify products that are part of the VoltAIRe programme.
Objective: 100% of our products traceable by 2025Tracing for increased transparency and performance
A process was launched in 2022, making traceability information available to our customers up to the knitting or weaving stage for 100% of the ready-to-wear and textile accessory collection, and up to the stitching stage for 100% of the shoe collection, in compliance with the French AGEC law.Since 2023, to go even further and gradually provide information from the origin of raw materials, Zadig&Voltaire has been working in partnership with Fairly Made®, which offers a traceability and product impact measurement solution.
Since 2024, the project has enabled the brand to gradually provide more traceability information and take its precise assessment of the environmental impact of its products further, in order to improve their performance.In parallel, the certification process for an increasing number of products throughout the entire supply chain, launched by Zadig&Voltaire in 2021, also contributes to making the traceability process more reliable and ensuring that each stage meets requirements in keeping with the company’s standards and industry best practices.

Roll-out of the zero virgin plastic made from fossil fuels ambitionZadig&Voltaire is also working to eliminate virgin plastic made from fossil fuels. By end of 2025, all polybags used to package and protect products are made from a biobased material derived from sugar cane or a recycled material, and are recyclable.
The brand will gradually roll out its approach across all packaging to achieve 100% packaging made from sustainable and recyclable materials and the elimination of virgin plastic made from fossil fuels by 2025.
