What is a life cycle assessment of a textile product?
A life cycle assessment (LCA) is a method to quantify the environmental impact of a product across its life cycle. For a textile product this means fibre production, yarn spinning, fabric formation, dyeing and finishing, cutting and sewing, distribution, use (washing and drying) and end of life. LCA is standardised in ISO 14040 and ISO 14044. It has four phases:
- 1Goal and scope. What is assessed, for whom, with which boundary and functional unit.
- 2Inventory. All inputs (materials, energy, water) and outputs (emissions, waste) per process.
- 3Impact assessment. Inventory data is converted into impact categories with a characterisation method.
- 4Interpretation. Hotspots, sensitivity, limitations and conclusions.
The knowledge gap and the regulatory clock
Most textile companies now understand that product-level environmental data will be a licence to operate. Fewer understand how an LCA works or which data a supplier must deliver. This is the gap: knowledge, not intent. Three EU instruments make the gap urgent.
The direction for methodology is the Product Environmental Footprint Category Rules (PEFCR) for apparel and footwear. These are still under development. No tool can claim PEFCR compliance today. A platform should be built in that direction and say so plainly.
What the scope of an LCA result must state
A result without a stated scope cannot be interpreted or compared. Four elements must be present.
Impact categories
An impact category is one type of environmental effect. Climate change is one. Water use is another. A carbon footprint reports one category. An LCA-based impact measurement reports several. The four categories that are most robust for textiles with current data availability are global warming (kg CO₂-eq), fossil resource use (MJ), water use (L) and land use (m²). Chemical and human toxicity categories exist in the ReCiPe method but depend on disclosed chemical formulations and complete safety data sheets, which the textile chain rarely provides. A platform that reports toxicity from incomplete data produces a number that can be wrong by an order of magnitude.
Life cycle stages and system boundary
Cradle-to-gate covers raw material through the factory gate. Cradle-to-grave adds distribution, use and end of life. The use phase (washing, drying) can be a large share of the impact for garments that are washed often. A platform should let the user select the boundary and show results per supply chain step.
Functional unit
The functional unit is the reference to which all results are related. For textiles the standard unit is 1 kg of product. Results can also be expressed per product unit, and, in the cradle-to-grave boundary, per wash or per wear. Two products can only be compared when the functional unit is the same.
Characterisation method
The method converts inventory data into impact categories. ReCiPe 2016 Midpoint (Hierarchist) is a widely used method developed in the Netherlands (RIVM, Radboud University, Leiden University, PRé Sustainability). The EU Environmental Footprint (EF) method is the method that PEFCR will use. A platform must name its method with every result.
bAwear Score calculates cradle-to-gate or cradle-to-grave, with results per supply chain step.
Data quality: the factor that decides everything
The result of a textile LCA is only as good as its data. Three data types exist.
A company that lacks primary data from spinning, weaving and fibre production should choose a platform with strong textile-specific default data. The default should be a worst-case value, not an average. A worst-case default protects against an understated result and improves when primary data is added. This is the approach bAwear Score takes: more than 200 predefined worst-case product scenarios that the user overwrites with primary data step by step.
What LCA software for textiles must do
How an SME starts: the three-step route
- 1Screen. Run an indicative LCA on the products that represent the largest share of volume. Use the tech pack data. Find the hotspots. Time: minutes per product.
- 2Improve the data. Ask the suppliers of the hotspot processes for primary data. Overwrite the defaults. Watch the result move. Time: weeks, in parallel with normal sourcing conversations.
- 3Review where a claim is needed. For the products that go into external reporting or B2B claims, move to a reviewed assessment with documented assumptions, prepared for independent third-party review.
This route builds knowledge inside the company. By the time the DPP delegated act for textiles is adopted, the company has product data, a data collection routine and supplier relationships that deliver primary data.
Where bAwear Score fits
bAwear Score is an LCA-based environmental impact measurement platform built for the textile and apparel industry by bAwear B.V. in the Netherlands, powered by SimaPro. It applies ReCiPe 2016 Midpoint (Hierarchist) in line with ISO 14040/14044 and reports four impact categories: global warming, fossil resource use, water use and land use. It covers cradle-to-gate and cradle-to-grave with results per supply chain step, with 1 kg of textile product as the standard functional unit. Data comes from Ecoinvent 3.12 and bAwear's proprietary textile database, including a generic textile module developed with PRé Sustainability. Two tiers exist. Quick Score gives indicative results in 5 to 10 minutes from more than 300 predefined worst-case scenarios. Expert gives reviewed results with documented assumptions, prepared for independent third-party review. Bulk upload and an API connect the platform to PLM, ERP, traceability and DPP systems. Chemical and human toxicity indicators are excluded by design.
Quick Score results are indicative and intended for internal decision support and reference product comparison. They do not replace a full ISO 14040/14044 LCA with critical review.
