MATERIAL LITERACY · 4 MIN READ

Natural is an origin. It is not an impact score.

Make room for context when comparing what clothes are made of.

Define the comparison

A kilogram of fiber, a square meter of fabric and a garment worn one hundred times are different comparison units. Before accepting an impact claim, find the functional unit, system boundary and assumptions.

Look beyond the raw material

Farming, chemical processing, dyeing, energy supply, transport, laundering and disposal can all contribute. Two fabrics sharing a fiber name may have very different production histories.

Keep distinct questions distinct

Animal welfare, worker conditions, greenhouse emissions, water stress and microfiber release are not interchangeable. A strong result on one measure does not settle the others.

Prefer useful specificity

Ask for the growing region, processing plant, composition and expected lifetime. A modest, verifiable statement is more useful than an unexplained green score. This atlas deliberately avoids a single universal sustainability rating.
