TCF POST Special Report
Amsterdam / Hong Kong / Oakland, Calif. – A coalition of the global apparel industry’s leading sustainability organisations has unveiled an updated framework for classifying supply chain processes—a technical development that could significantly influence how brands source products, report environmental impacts, and comply with increasingly stringent sustainability regulations.
The apparel alliance—comprising the Apparel Impact Institute (Aii), Cascale, Textile Exchange, and the ZDHC Foundation—has launched Version 2 of the Supply Chain Taxonomy, a harmonised classification system covering the textile, clothing, leather, and footwear (TCLF) sectors. Designed to establish a common language across the global value chain, the revised framework aims to improve consistency, transparency, and collaboration among brands, manufacturers, suppliers, certification bodies, and regulators.
Why It Matters
For years, the fashion industry has struggled with fragmented sustainability reporting, where brands, suppliers, certification programmes, and digital platforms often use different definitions for identical manufacturing processes. The lack of standardisation has increased audit costs, complicated emissions reporting, and reduced confidence in ESG data.
Version 2 of the Supply Chain Taxonomy seeks to address these longstanding challenges by creating a shared classification framework that enables organisations across the supply chain to describe products, facilities, and manufacturing processes in a consistent manner. This common language is expected to improve data quality, strengthen sustainability reporting, reduce duplication of reporting efforts, and support better-informed business decisions across the industry.
Wet Processing Recognition Marks a Major Technical Shift
One of the most significant revisions in the updated taxonomy concerns wet processing—including dyeing, printing, washing, and finishing—which accounts for a substantial share of the industry’s water consumption, chemical use, and greenhouse gas emissions.
Under the original 2024 framework, wet processing was largely associated with Tier 2 suppliers. Version 2 recognises that these processes occur across multiple supply chain tiers, providing a more accurate basis for emissions accounting, environmental impact assessment, and sustainability reporting.
The revised approach is expected to improve carbon accounting while helping brands identify where environmental impacts actually occur and where decarbonisation investments can deliver the greatest benefits.
Industry leaders involved in developing the framework emphasised that shared definitions are fundamental to improving data quality, strengthening collaboration, and accelerating the industry’s sustainability transition. They also noted that no single organisation can drive transformation alone, making common standards essential for industry-wide progress.
What It Means for Textile and Apparel Manufacturers
For textile mills, garment manufacturers, dyeing and finishing facilities, leather processors, and footwear producers, the updated taxonomy represents far more than a reporting exercise. It is expected to become an increasingly important operational framework as global brands demand higher-quality sustainability data from their suppliers.
Key implications include:
- More accurate and internationally comparable ESG reporting.
- Improved documentation and digital traceability across manufacturing processes.
- Better preparedness for emerging due-diligence and sustainability disclosure regulations.
- Reduced duplication of sustainability audits and reporting requests.
- Stronger benchmarking opportunities through harmonised process classifications.
Manufacturers that align their operations with the revised taxonomy are likely to find it easier to meet the sustainability expectations of international customers while reducing administrative complexity.
Implications for Global Sourcing
The updated taxonomy is also expected to reshape sourcing strategies.
As apparel brands intensify their decarbonisation commitments and strengthen ESG due diligence, procurement teams are increasingly seeking suppliers capable of delivering reliable, standardised sustainability data. The revised framework provides a common basis for comparing supplier performance across countries, factories, and production processes.
Early adoption could therefore become a competitive advantage for manufacturers, improving their position during supplier selection, contract renewals, and long-term sourcing partnerships.
Building the Foundation for the Fashion Industry’s Digital Future
Beyond sustainability reporting, the revised taxonomy is expected to become foundational infrastructure for the fashion industry’s growing digital ecosystem.
As Digital Product Passports, supply chain traceability platforms, carbon-accounting tools, and ESG reporting systems become more widely adopted, a standardised classification system will help ensure these technologies operate using consistent data structures.
Greater interoperability between competing sustainability platforms could ultimately improve transparency for regulators, investors, brands, and consumers while supporting more credible environmental claims throughout the global apparel supply chain.
What to Watch
The rollout of Version 2 is likely to influence sourcing and sustainability strategies across the global fashion industry over the coming years. Industry observers will be watching whether major brands begin requiring suppliers to report using the updated taxonomy, how rapidly digital traceability and carbon-accounting platforms integrate the revised classifications, whether the multi-tier wet-processing model changes emissions attribution across the supply chain, and how future annual updates respond to evolving regulations and stakeholder feedback.
As sustainability reporting becomes increasingly data-driven, the updated Supply Chain Taxonomy could become as fundamental to the apparel industry as quality management and product compliance standards. For manufacturers, exporters, and sourcing professionals, early adoption may not only simplify compliance but also strengthen competitiveness in an increasingly transparent global fashion marketplace.
Footnote: The apparel alliance was established in 2020 to align sustainability tools, reduce duplication across industry initiatives, and accelerate decarbonisation throughout the apparel value chain. Collectively, its members are working towards reducing greenhouse gas emissions across the global apparel supply chain by at least 45% by 2030.
