SUSTAINABILITY / SECTOR LENSES / RETAIL & CONSUMER
Fashion & Apparel
Digital product passports, fibre traceability, mass-balance limitations, and the MRV gap from cotton farm to finished garment. Where supply chain transparency meets sustainability disclosure.
In brief
Fashion and apparel is one of the most complex sectors for sustainability disclosure — not because the frameworks are unusual, but because the supply chain is so deep, opaque, and geographically dispersed that connecting brand-level claims to physical supply chain reality is genuinely difficult. A typical fashion supply chain runs five or more tiers: brand to tier 1 factory (cut-make-trim) to tier 2 mill (fabric and dyeing) to tier 3 spinner (yarn) to tier 4 producer (fibre farm or chemical plant). Most brands know tier 1; some know tier 2; very few have reliable data beyond that.
The EU's Digital Product Passport — mandatory for textiles under ESPR from approximately 2027 — will require disclosure of fibre origin, processing locations, and chemical profiles for each product. Mass-balance accounting cannot satisfy this requirement. The brands building real supply chain data now will be ahead when the mandate arrives.
Actor roles in this sector
Set sustainability requirements for collections, carry disclosure obligations, and are the visible face of environmental claims. Facing ESPR, CSRD, and Green Claims Directive simultaneously.
Cut-make-trim factories directly contracted by brands. The most audited tier — but audit coverage drops sharply below here. Increasingly required to provide energy and water data for brand Scope 3 reporting.
Weaving, dyeing, finishing, printing. The tier where most chemical use and water consumption occurs. Bluesign and ZDHC certification applies here. Most brands have limited visibility into this tier.
Cotton farmers, wool producers, viscose/lyocell pulp processors, synthetic fibre manufacturers. The landscape layer — where ecosystem services, water use, and soil health are determined. The least visible tier in most supply chains.
GOTS, GRS/RCS, BCI, Bluesign, OEKO-TEX, Textile Exchange, ISEAL. Define what "sustainable fibre" means, certify producers and processors, and provide the claims infrastructure that brands rely on — with very different levels of traceability rigour.
TextileGenesis, Sourcemap, Fibertrace, Applied DNA Sciences. Digital ledgers, physical tracers, isotope testing. The emerging MRV infrastructure that can close the gap between claims and physical supply chain reality.
The framework landscape
Fashion and apparel operates across regulatory requirements (ESPR, CSRD, EUDR, EPR), voluntary certifications (GOTS, GRS, Bluesign, OEKO-TEX), and industry-wide initiatives. The regulatory pressure is accelerating rapidly, and the certification layer has significant variation in traceability rigour.
Regulatory obligations
From 19 July 2026 the EU bans the destruction of unsold apparel and footwear under the ESPR, with phased exemptions for the smallest firms. A direct hit to the overstock-and-destroy model: brands must redesign for reuse, resale, donation and recycling rather than disposal. The nearest hard deadline in fashion sustainability.
Textiles is one of the first product categories being addressed under ESPR. A Digital Product Passport (DPP) will be required for textile products, disclosing fibre composition, country of origin, durability, repairability, and recyclability. The EU DPP central registry goes live July 2026, with textile-specific passport requirements phasing in from around 2027. This is the forcing function that will require real supply chain traceability, not mass-balance accounting.
The overarching EU policy for fashion sustainability. Drives ESPR, EPR, eco-design, and green claims requirements. Sets the direction: all textiles placed on the EU market should be durable, repairable, and recyclable by 2030.
Extended Producer Responsibility for clothing and household textiles. France has Refashion — the most mature textile EPR scheme globally. EU Textile Strategy calls for all member states to implement EPR by 2025. UK is consulting. Producers and importers pay per item; funds repair, reuse, and recycling infrastructure.
Fashion has one of the highest rates of unsubstantiated environmental claims of any sector. Terms such as "sustainable collection," "eco," "conscious," and "recycled" require specific substantiation. Independent verification required before any claim is made publicly.
ESRS S2 (workers in the value chain) is particularly significant for fashion given labour conditions in garment manufacturing. E1 (climate), E5 (circular economy), and G1 (upstream supply chain) are all material. Supply chain disclosure requirements under ESRS are more extensive than any previous regime.
Leather and rubber are forest-risk commodities under EUDR. Relevant for footwear, leather goods, accessories, and garments using elastic. Plot-level traceability to cattle farms or rubber plantations required for goods placed on the EU market. Now postponed to 30 December 2026 for large operators and 30 June 2027 for micro and small operators.
Voluntary certifications & industry tools
The premium certification for organic fibre. Covers the entire supply chain from farm certification (USDA/EU organic) through spinning, weaving, dyeing, and finishing. Chain of custody required at every tier — genuine traceability. Volume-limited relative to total cotton production.
Textile Exchange standards for recycled content. GRS requires chain of custody through the full supply chain and covers social and environmental processing requirements. The dominant standards for recycled polyester, recycled cotton, and recycled nylon.
The largest cotton sustainability programme globally. Uses mass-balance accounting: Better Cotton is commingled with conventional cotton after the gin, with no physical traceability from farm to finished garment. A brand can claim to "source Better Cotton" without any Better Cotton physically present in its products. Important limitation to understand before making claims.
Responsible manufacturing standard for chemicals, water, and energy at fabric mills and dye houses (tier 2). Covers chemical management, wastewater treatment, energy efficiency, and worker health and safety. Applied at processing stage, not at fibre or finished garment level.
STANDARD 100 certifies that a finished product has been tested for harmful substances. MADE IN GREEN adds traceability and social responsibility criteria — products are traceable to certified facilities through a scannable label.
Originally the dominant industry self-assessment tool for environmental performance. Severely damaged in 2022 when Norway's Consumer Authority found brands were using Higg scores to make consumer-facing claims that were misleading. Now under reform. Still used internally for benchmarking; treat consumer-facing Higg claims with caution.
MRV and traceability: the distinctive challenge
The gap between what the frameworks require and what fashion supply chains can actually demonstrate is wider here than in almost any other sector. Most sustainability claims in fashion rest on certifications that cover only part of the chain, or on mass-balance accounting that provides no physical traceability at all.
The cotton traceability gap
Cotton is grown across millions of smallholder farms — average farm size in India under 2 hectares, in West Africa 1-3 hectares. Aggregators and ginners lose farm-level identity. Better Cotton uses mass balance: the physical fibre is not traceable. GOTS requires farm certification but covers a small fraction of global volume. Most brands claiming sustainable cotton sourcing cannot demonstrate physical traceability to the farm where it was grown.
The ESPR forcing function
The Digital Product Passport will require disclosure of fibre origin, processing locations, and chemical profiles. Mass-balance accounting cannot satisfy a DPP — it requires actual data about the physical product. Brands that have mapped their tier 2 and tier 3 supply chains and built data relationships with mills and spinners will be ahead when DPP is required (~2027-2028).
Physical tracing technologies
Emerging approaches to close the traceability gap: isotope testing (verifying geographic origin by matching the isotopic signature of cotton to its growing region); DNA tagging (Fibertrace, Applied DNA Sciences — inorganic or biological markers applied to fibre that persist through processing); digital ledgers (TextileGenesis, Sourcemap — blockchain-style chain of custody from spinner to brand). Each has limitations; none is yet at scale for commodity cotton.
Scope 3 Category 1 dominance
For most fashion brands, Scope 3 Category 1 (fibre, fabric, trims, and manufacturing) represents 70-90% of total GHG footprint. Meaningful climate action requires engaging the supply chain, not just measuring it. SBTi commitments require credible Scope 3 reduction pathways — which means working with mills and farmers on energy and land use.
The landscape connection
Fibre production is a landscape activity. Cotton fields in Rajasthan, Gujarat, the Mississippi Delta, Mali, and Uzbekistan are the landscapes where fashion supply chains originate — and where the ecosystem service implications sit. Cotton is one of the most water-intensive crops (approximately 10,000 litres per kilogram of fibre), a major user of pesticides, and a driver of soil degradation in several key growing regions.
TNFD dependency disclosure for fashion companies requires assessment of nature dependencies and impacts in the landscapes that produce their fibres. SBTN land and freshwater targets require engagement with specific geographies, not aggregate statistics. The traceability infrastructure that fashion needs for ESPR compliance is the same infrastructure that enables landscape-level MRV — connecting the brand's disclosure obligation directly to the field where the cotton grows.
Agriculture & Food Systems — production end →The Pandion view
Mass balance is a transitional tool, not a sustainability solution — and treating it as one is a growing regulatory and reputational risk.
A brand can claim 100% Better Cotton sourcing while none of the physical cotton in its garments was grown to Better Cotton standards. Legally defensible under current rules; but it will not satisfy ESPR digital product passport requirements. Brands that understand this distinction and can communicate it honestly are in a better position than those using it as a headline claim.
The ESPR digital product passport is the most consequential regulatory development in fashion sustainability since REACH.
REACH transformed how the industry manages chemicals in production. ESPR will transform how brands manage and disclose product data — as a consumer-facing record, not a B2B compliance exercise. Every product will carry a verifiable record of its sustainability credentials. The brands building traceability infrastructure now are making a strategic investment, not completing a compliance exercise.
The destruction ban closes the overstock escape hatch before the digital product passport even arrives.
From 19 July 2026 brands can no longer quietly destroy unsold stock in the EU. Combined with the digital product passport, the over-produce-and-write-off model stops working in two directions at once: you cannot hide the overstock, and you cannot dispose of it. The commercial answer is designing for resale, repair and recycling, not just cleaner sourcing claims.
The fashion sector's MRV problem is the same as agriculture's, it just hasn't been named yet.
TNFD, SBTN, and the corporate biodiversity agenda are pushing companies to understand nature dependencies in specific landscapes. For fashion, that means understanding what cotton farming does to soil and water in Gujarat. The tools that will enable this, isotope tracing, satellite monitoring, certification at aggregation point, are the same tools emerging in regenerative agriculture. Fashion and agriculture are converging on the same infrastructure challenge.
