As responsible sourcing becomes an ever more important defining measure of credibility across luxury, fashion faces particularly complex challenges. For luxury fashion, risk runs from raw materials through to the processing that turns textiles and leather into finished products. It spans several stages of the supply chain, and means it is essential brands understand both where their materials come from, and how they are made.
Positive Luxury’s recent guide, Responsible Sourcing in Luxury, explores how brands can identify, assess and work with responsible suppliers. For fashion, this means backing material claims with evidence and building visibility further upstream.
WHERE THE RISK IS CONCENTRATED
One of the core challenges for fashion brands is validating the claims made about new materials and processes. Recycled fibres, bio-based leather alternatives and low-impact dyes offer exciting opportunities for innovation, but their sustainability credentials need evidence behind them before they can be trusted.
Chemical management is another priority, with dyes, inks and wastewater from textile and leather processing remain significant sources of environmental harm (and regulatory attention). Durability and scalability add further complexity: materials that perform well in small trials need to demonstrate that they can meet expectations for quality and longevity at commercial scale.
Leather and animal-based textiles bring additional sourcing and processing concerns. Human rights risks in sourcing regions also require attention, particularly where traceability stops at Tier 2 and leaves raw material suppliers out of view. For natural and agricultural inputs – key to fashion – climate and biodiversity risks begin at source and affect the wider supply chain.
WHAT GOOD LOOKS LIKE
There are three key approaches to mitigation that brands can take:
- Require third-party verification of material and impact claims, with evidence to support supplier assurances
- Adopt ZDHC (Zero Discharge of Hazardous Chemicals) guidelines to help manage chemical and wastewater risks in dyeing, printing and tanning
- Test new materials for performance and durability at commercial scale before introducing them into wider production
INSPIRATIONAL CASE STUDIES
Burberry has adopted ZDHC wastewater guidelines and is expanding its testing to strengthen oversight of chemical management and water quality during textile processing.
Piper & Skye uses invasive species skins alongside chrome-free tanning and non-toxic processing methods. This helps reduce environmental impact while supporting ecosystem balance, rather than working against it.
Ocean+Main and WE-AR4 demonstrate different approaches to circular sourcing through the use of recycled, upcycled or deadstock materials. These models put existing resources to use and reduce reliance on virgin inputs.
KEY TAKEAWAYS FOR FASHION BRANDS
- Make chemical management part of sourcing – use ZDHC guidelines to inform supplier requirements wherever dyeing, printing or tanning takes place
- Validate materials before scaling – test performance and durability under realistic production and use conditions, and ensure public impact claims have evidence behind them
- Ask for independent verification – prioritise third-party evidence for material categories with significant sourcing and processing risks
- Trace materials back to source – extend supply chain mapping beyond Tier 2, focusing on regions and raw materials with the greatest human rights and biodiversity risks
- Put existing materials to use – explore where recycled, upcycled or deadstock inputs could meet product requirements and reduce demand for virgin resource
