Reminder of objectives
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 our key raw materials come from certified supply chains
• Zero virgin plastic made from fossil fuels
• 100% of our packaging made from traceable, recycled and recyclable materials from certified sources
• 100% traced products

Cotton
Zadig&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.
Leather
Leather is also one of the materials that are part of the brand’s DNA. Zadig&Voltaire has committed by 2025 to only sourcing leather from certified Leather Working Group (

Polyester
Polyester 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.
Viscose
Using viscose made from fibres certified as coming from responsibly 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 responsibly managed forests.
Traceability
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 2025
Tracing 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.
Packaging
Zadig&Voltaire is committed to using packaging made from 100% traced materials from certified, biobased or recycled sources, and 100% recyclable.
Traced, certified and recyclable paper and cardboard packaging: e-commerce boxes, store bags, shoe boxes
In all countries, 100% of the brand’s store bags and e-commerce boxes are made from certified paper/cardboard, composed of a mix of certified traced, recycled fibres from responsibly managed forests, and are 100% recyclable. • The paper used to make our shopping bags is certified and contains at least 50% recycled fibres. • The cardboard used to make our e-commerce boxes contains at least 50% recycled fibres. • The cardboard used to make our shoe boxes contains at least 50% recycled fibres.
Roll-out of the zero virgin plastic made from fossil fuels ambition
Zadig&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 recycled material and are recyclable. The brand will gradually roll out its approach across all packaging to achieve 100% packaging made from certified and recyclable materials and the elimination of virgin plastic made from fossil fuels.
Promoting the circularity of materials used for our textile packaging: leather goods, jewellery and shoe pouches
The pouches provided with Zadig&Voltaire products are made from 100% recycled and certified cotton and/or polyester.

Making a commitment that goes beyond just materials by means of a certification process for the entire supply chain
In addition to its objective to use 100% certified key raw materials, Zadig&Voltaire is taking measures in an effort to have its entire supply chain certified for the majority of its products. This process ensures that traceability details are reliable and that each manufacturing step meets requirements in keeping with the brand's standards.
In this context, Zadig&Voltaire has been certified since 2021 in accordance with recognised and particularly rigorous standards such as The GOTS certification guarantees the organic status of a textile from harvesting of the raw material to finished product.
