About the Benchmark for Fibres

The Fibre Benchmark compares the environmental impact of the most commonly used fibres in the garment industry, supporting you to shift to more sustainable alternatives.

Our Benchmark is used by brands from G-Star to H&M and is based on robust Life Cycle Analysis (LCA) data that has been independently verified by our partner Brown and Wilmanns Environment (BWE LLC).

The Benchmark also serves as the basis of measurement and scoring for the fibre components of the MADE-BY Scorecard.

The Methodology behind the Benchmark

By looking at the production process of natural and man-made fibres and associated human and environmental impacts, we ranked 28 fibres on six common parameters.

The six parameters have been given different weights in terms of impact. Greenhouse gas emissions human toxicity and eco-toxicity are weighted to 20% each, while energy, water and land use has been given a 13.33% weighting.

Based on these parameters, each fibre was scored and placed into one of five classifications: Class A to Class E. An additional category, ‘Unclassified’, has been added, in which fibres that are not (yet) part of this Benchmark are listed due to a lack of available robust data. Over time, we aim to incorporate these fibres into one of the five defined classes as further information becomes available.

In 2016, we will complete a methodological and full data update of the Environmental Benchmark for Fibres in partnership with an expert steering committee.
