Create LCIs
Create CFs
LCIs needed to know
which chemicals to
develop CFs for
CFs needed to know which
chemicals that are relevant
to inventory
CAS REGISTRY has reached 100 million
chemical substances…
Create LCIs
>15,000 different chemicals
are used in the textile industry
LCI = Life Cycle InventoryCF = Characterisation factor
Create LCIsFunction-based nomenclature for
inventory data

Calculating the toxicity footprint of Swedish clothing consumptionSome particular conditions for Swedish clothing consumption are shown below.
Yearly consumption per Swede:10 kg 6 000 SEK50 pcs
European landfill ban on combustible waste
implemented in 2002
Results: Freshwater ecotoxicity impacts from the Swedish apparel sector over one year
