New paper sets out considerations for the responsible use of LCA data across the fashion, textile, and apparel industry

Textile Exchange has released a comprehensive new position paper outlining best practice for the responsible use of Life Cycle Assessment (LCA) data in the fashion, textile, and apparel industry. LCA is widely used by the industry to measure a product’s environmental impact at different stages of its journey—from raw material production to manufacturing, transportation to end-of-life.


This paper, Ensuring Integrity in the Use of Life Cycle Assessment Data, provides guidance on how to use LCA data, and—equally importantly—how it should not be used.

It also promotes the need to move beyond what is currently covered in LCA methodology to capture a more holistic view, including nature, animal welfare, and social impacts.

The paper is intended for anyone looking to develop a greater understanding of the use of LCA data in the textile industry—particularly for brands using LCA data directly or those who rely on it for their impact modeling or progress tracking.

The paper includes a call for industry-wide integrity in the use of LCA data, listing key recommendations, such as:

+ Only using LCA data when there is a full understanding of the key assumptions, methods, and use cases. To help, all assumptions, methodological decisions, limitations, and underlying datasets should be fully documented in studies.

+ Not comparing LCA data between:

   + +  Fiber or material categories or geographies, for example between natural and synthetic fibers.

   + +  Separate LCA studies, or within a study, unless it is specifically a comparative LCA study.

   + +  Different industry databases, which collect and store LCA data, as each of these databases applies differing methodologies and assumptions.

+ Consideration of an LCA+ approach that includes measuring impact areas such as biodiversity, soil health, animal welfare, and livelihoods.

The paper also includes sections on:

+ Understanding Life Cycle Assessment, including a definition of what it is, why it’s used, and the steps to follow to conduct an LCA study.

+ The challenges and limitations of using LCA in the textile industry.

+ Textile Exchange’s work with LCA studies.

The paper forms part of Textile Exchange’s commitment to convening actors across the supply chain to improve the impact data available for the industry. The paper is complimentary to other work and guidance being developed across the fashion, apparel and textile industry on the responsible use of LCA data. Currently, Textile Exchange is running seven LCA studies across different material types and diverse geographies globally to help fill some of the significant data gaps. Where relevant and possible, the studies will include an LCA+ approach.

These will be released between the end of the year and 2027 in the following order:

+ Cotton (organic, conventional, regenerative practices, and recycled), Q4 2025

+ Cashmere, Q4 2025

+ Responsible Mohair Standard (RMS) mohair, Q4 2025

+ Polyester (recycled and virgin), Q4 2025

+ Responsible Wool Standard (RWS) wool, Q2 2026

+ Leather (bovine, ovine, and caprine), Q5 2026

Textile Exchange publishes cotton Life Cycle Assessment study to strengthen impact data

Textile Exchange has published the first in a series of seven Life Cycle Assessment (LCA) studies designed to improve the quality and robustness of environmental impact data for raw material production across the fashion, textile, and apparel industry. The first LCA study focuses on cotton and addresses critical data gaps and methodology variability through new high-quality data across key producing countries. The study includes organic, regenerative, recycled, and country averages for conventional cotton production systems, providing a clearer picture of the associated environmental impact.

New Gravimax MMX-R X-ray sensor platform opens up new application fields

The demands placed on quality control in web-based production processes are increasing: materials are becoming more complex, basis weights are varying more widely, and at the same time, pressure is growing to make processes more efficient and transparent. Precise measurement data across the entire web width has therefore become a key factor in ensuring stable production processes. With its new Gravimax MMX-R sensor platform, Mahlo introduces a radiometric measurement solution designed to set new standards in determining basis weight and material composition. The platform combines advanced X-ray technology with newly developed signal processing, enabling measurement tasks that previously often required multiple sensor technologies.
