Sustainability software for fashion falls into five types: product-level environmental data (LCA) platforms, supply chain traceability, corporate carbon accounting, ESG reporting and due diligence, and facility data. The right fit depends on the request in front of you. For most fashion brands the deciding factor is the product data underneath: footprints built within your supply chain and reviewed by specialists can feed retailer questionnaires, digital product passports, Ecoscore and your Scope 3 from one record. Some platforms span several types; Green Story covers all five from one record.
Green Story is one of the vendors in this guide, and appears in every type by the module that covers it. Every other vendor is described from its own website; each list is alphabetical.
How we chose the vendors: a vendor is listed if an independent analyst or the trade press has named it in the last 18 months, or if it is a major platform fashion buyers commonly evaluate.
Why the data is the hard part
Most of a garment's footprint sits upstream, in fibre production, spinning, dyeing and finishing at mills you may never have visited. Retailers ask for product footprints, regulation brings digital product passports and environmental cost labels, and your own targets need a Scope 3 baseline. Each request draws on the same facts, held by your suppliers.
That is why the useful way to compare software is by where its data comes from and what it can produce from it, more than by the dashboard.
The five types of sustainability software for fashion
Product-level environmental data (LCA) platforms
Footprints per product, modelled from materials and processes, which then feed passports, eco-scores, eco-design and Scope 3. Fits: brands answering product-level requests from retailers and regulators.
- CarbonfactSoftware for apparel and footwear brands and suppliers to measure and reduce product and corporate impact. Vaayu joined Carbonfact in May 2026.
- Fairly MadeTraces fashion supply chains and measures product impact through LCAs, covering DPP, AGEC and the French environmental cost.
- Green Story Product LCAFootprints per style for fashion, home textiles and footwear, built from your own suppliers' data and signed off by LCA specialists; feeds DPPs and Ecoscore.
- GreenStitchSustainability software for fashion and lifestyle brands covering carbon accounting, product LCA, ESG reporting and a DPP module.
- SpheraLCA for Experts, a general-purpose tool for LCA practitioners to model product life cycles across industries, with Sphera's database.
Supply chain traceability platforms
Maps suppliers tier by tier and holds the evidence behind each link, for due diligence, origin claims and forced-labour rules. Fits: brands proving where products were made.
- Green Story TraceabilityTraces every order tier by tier from the purchase order, each trading partner confirming their own link, with the evidence on record.
- RetracedSupplier collaboration, multi-tier traceability and product compliance for fashion and textile companies.
- SourcemapCross-industry supply chain mapping for risk, customs compliance, due diligence and EUDR.
- TrusTraceMaps fashion, footwear and textile supply chains and centralises supplier data for traceability, due diligence and compliance.
Corporate carbon accounting platforms
Company-level Scope 1, 2 and 3 for targets and disclosure. Purchased goods are usually the largest share of a fashion brand's footprint, so check how each platform calculates it. Fits: brands setting targets or reporting under CSRD or CDP.
- Green Story Carbon accountingScope 1–3 and SBTi targets, with purchased goods built up from the same product footprints, so company and product figures reconcile.
- GreenlyCarbon accounting to measure, report and reduce emissions, plus product LCAs. Joining forces with Normative, announced September 2026.
- PersefoniCarbon accounting and sustainability management for emissions measurement, disclosure and decarbonisation planning.
- Plan ASoftware to measure, report and reduce corporate emissions, with fashion among its industries. Agreed to be acquired by Diginex in January 2026.
- SweepTracks ESG and carbon data for reporting frameworks including CSRD and CDP.
- WatershedMeasures, reports and acts on sustainability data, including carbon accounting and product footprints.
ESG reporting and supplier due diligence platforms
Collects supplier ESG answers, screens risk and assembles disclosures. Fits: sustainability and compliance teams running supplier programmes.
- Green Story Compliance and reportingCompliance readiness by framework, supplier questionnaires, risk and audit-ready reports from the same verified record.
- SweepAlso covers ESG reporting alongside carbon (see Type 3).
- WorldfavorSupply chain due diligence: supplier ESG data, risk screening and corrective actions, with a textile and apparel offer.
Facility and industry-standard data platforms
Where factories report standardised facility data that brands then read. Fits: brands and suppliers using the Higg Index.
- Green Story Data collectionFacility data collected with your suppliers and verified on site by Green Story's analysts, across 35+ manufacturing countries.
- WorldlyConsumer goods companies collect facility data and calculate product impacts; the Higg FEM is available exclusively on Worldly.
How the types work together
Most brands end up with product data at the centre. Traceability tells you which facilities made each product; product footprints turn that chain into figures; carbon accounting rolls those figures up to the company; passports and eco-scores publish them. When one record feeds all four, the numbers reconcile, and suppliers answer once.
What to check before you buy
| Check | Why it matters | Ask the vendor |
|---|---|---|
| Where the data comes from | Industry averages describe a typical product; your suppliers' data describes yours. | “What share of this footprint is measured from our suppliers, and is it shown on the result?” |
| Who checks it | A footprint is a model, and model choices change the number. | “Who reviews the model before we publish a figure?” |
| Standards | Retailers and regulators name their methods. | “Which standards do you follow: ISO 14067, ISO 14040/44, PEF, GHG Protocol?” |
| Supplier experience | Suppliers answer many buyers; the easier it is, the better the data. | “Do our suppliers answer once and reuse it for every buyer?” |
| Outputs from one record | Separate tools for each request give numbers that disagree. | “Do our product footprints and our Scope 3 come from the same data?” |
| Time to first result | Deadlines arrive before a full rollout does. | “What does a baseline take, and what do you need from us?” |
| Ownership and export | Your evidence should travel with you. | “Can we export every figure with its evidence?” |
Which type fits your situation
- A retailer wants product footprints
Start with a Type 1 platform: it answers per style and builds the base for everything else.
- You are setting a target or reporting under CSRD
A Type 3 platform, ideally fed by product-level data so purchased goods reflect what you actually buy.
- Due diligence, forced labour or EUDR
A Type 2 traceability or Type 4 due diligence platform, with evidence held per supplier.
- Several requests at once
One platform whose single record covers products, traceability, passports and Scope 3, so suppliers answer once.
One platform across all five types
Green Story covers all five types from one record: product footprints, traceability, Scope 1–3 and SBTi targets, compliance and reporting, and facility data, with digital product passports and Ecoscore published from the same data. Raya AI collects and structures supplier data; our analysts verify it at the facility and LCA specialists sign off every result. The data is built within your supply chain, with the source of every figure recorded.

Questions buyers ask
What is the best sustainability software for a fashion brand?
It depends on the request in front of you. Most fashion brands start with a product-level data platform, because retailer questionnaires, digital product passports, Ecoscore and Scope 3 all draw on product footprints. Choose one that builds those footprints from your own suppliers' data and has specialists review them.
Do we need separate LCA and carbon accounting tools?
Some brands run two. A platform that builds Scope 3 purchased goods up from product footprints and traced orders keeps the company footprint and the product footprints reconciled, because both come from the same primary data.
What software do we need for the EU Digital Product Passport?
Software that generates passports from the traced chain and the product footprint behind each item. For textiles, the European Commission plans to adopt the ESPR delegated act in Q4 2027, and companies then have a transition period of at least 18 months before the requirements apply. The EU's DPP Registry has been live since July 2026.
How much of a footprint can be measured rather than estimated?
It varies by supply chain and by season. Ask for the measured share to be shown on every result, so you can see it rise as more suppliers report.
Bring one style and one supplier.
