Impact data for denim, from indigo dyeing to garment finishing
Denim brands and mills use bAwear Score to calculate the impact of denim fabrics and jeans. Results show the share of fibre, indigo dyeing and garment finishing, and scenario comparison shows how alternative washing and finishing routes change impact.
What makes impact data hard in denim
Finishing varies per wash
Each wash look uses a different combination of water, chemicals and energy.
Cotton origin matters
Conventional, organic and recycled cotton give very different results.
Claims on water and energy
Low-impact finishing claims need numbers with a stated method.
Typical hotspots per supply chain step
Materials
Cotton cultivation drives water use and land use. Recycled content changes the picture.
Yarn
Ring or open-end spinning and the electricity mix.
Fabric
Indigo dyeing and weaving.
Product
Garment washing and finishing, making and transport.
