Verify Cotton Provenance in Textile Manufacturing
Sector: Secondary sector · Industry: Textile and clothing industry · Organisation: United Nations Economic Commission for Europe (UNECE), Stella McCartney, SÖKTAS · Maturity level: Pilot
The United Nations Economic Commission for Europe (UNECE) conducted a blockchain pilot with fashion brand Stella McCartney and cotton supplier SÖKTAS to trace a garment through the supply chain. The project verified the origin and processing steps of a cotton jersey T-shirt using tamper-proof digital records. This initiative demonstrates how transparent sourcing standards can advance sustainability across the global fashion industry.
Documentation status
- Project status: Pilot (as of 30 June 2023) — The pilot project for tracing a T-shirt was successfully completed in June 2023 by the UNECE and Stella McCartney.

Description
The United Nations Economic Commission for Europe (UNECE), in collaboration with Stella McCartney and SÖKTAS, has demonstrated how the origin of textile fibres can be fully controlled. In the highly fragmented fashion industry, it is often difficult for companies to trace under what conditions the raw materials used were actually obtained. The blockchain serves here as a shared, immutable ledger in which all processing steps from cotton harvesting to the finished garment are bindingly documented.
The pilot project was developed within the framework of the UNECE initiative for sustainability and circularity in the clothing industry. Together with the British fashion brand Stella McCartney and the Turkish textile producer SÖKTAS, the entire lifecycle of a cotton jersey T-shirt was mapped. All intermediate stages, from raw material cultivation through spinning to cutting, stored evidence of origin and quality criteria in the blockchain. By using uniform UN data standards, the solution is intended to be scalable for other global suppliers as well. Although no final figures on productivity increases are yet available, the project is regarded as an important practical proof of feasibility for regulatory transparency requirements.
Perspectives
B2B — organisations perspective
For companies, the process offers a uniform way to exchange certificates and evidence along the supply chain with trading partners in a tamper-proof manner. Brands can seamlessly verify and document compliance with their own sustainability criteria towards suppliers.
B2C — consumers perspective
End customers can be confident when purchasing fashion products that declared environmental standards and the origin of raw materials actually correspond to the facts. The verified chain creates credibility and protects against misleading advertising claims.
Employees perspective
Employees in operational purchasing and sustainability departments gain direct insight into verified transaction data from their upstream stages. Routine checks of static PDF certificates are replaced by automated or digitally stored verification paths.
Benefits
General
- Seamless verification of fibre origin along the production chain
- Reduction of risks related to greenwashing
- Standardised interfaces based on UN guidelines
B2B — organisations
- Increased evidential security towards regulatory authorities and customers
- Simplified exchange of evidence between suppliers and brands
- Improved risk management in deeply nested supply networks
B2C — consumers
- Reliable information about the ecological origin of clothing
- Greater trust in brand promises regarding sustainability
Employees
- Less manual effort in plausibility checks of delivery documents
- Central overview of verified supplier documents
Challenges
General
- High coordination effort when involving all upstream operations
- Dependence on correct initial recording of physical raw material quantities
B2B — organisations
- Willingness of smaller suppliers to provide granular production data
- Integration effort into existing inventory management and ERP systems
Employees
- Training time for new platforms and UN-specific data models
Technology foundation
The use case is based on the UNECE blockchain reference framework for sustainable supply chains in the clothing sector, where evidence across production stages is validated decentrally and immutably recorded.
Implementation examples
UNECE cotton traceability with Stella McCartney and SÖKTAS
Lack of end-to-end transparency in global textile supply chains makes it difficult to prove sustainable practices and exposes fashion brands to reputational risks.
UNECE tested seamless traceability of a cotton T-shirt based on blockchain technology with Stella McCartney and the Turkish supplier SÖKTAS.
As part of the pilot project, Stella McCartney and the supplier SÖKTAS documented the production and processing of cotton jersey according to the criteria of the UNECE Traceability Framework. Every step, from fibre through yarn to the finished garment, was recorded with digital evidence in a shared register. This created a verifiable life history of the garment, confirming the fibre's origin without gaps.
The pilot group overcame the fragmentation of processing steps and the insufficient linking of physical material flows with document checks.
