OEKO-TEX® with its partner Quantis, a leading sustainability consultancy, chose the Screening Life Cycle Assessment (LCA) approach to develop the tool.
A Screening LCA is easier, faster and less expensive than a full LCA – and it provides sufficient initial and credible insight into where a facility’s biggest carbon emissions and water impacts occur across its processing steps and for the types of fibres used.
Our tool methodology required a customized approach to calculate carbon emissions and water footprints addressing the specific needs and processes of textile production facilities. We applied elements from the Product LCA to measure the impacts at the material output level, and the Corporate LCA to measure the impacts at the overall facility level.
We incorporated recognized international databases and recommended standards:
- The Greenhouse Gas (GHG) Protocol recommends the IPCC 2013 100a approach for calculating carbon emissions (Co2-eq).
- The EU Commission recommends the AWARE methodology to measure the water impacts (m3).
Once a facility has input its data into the tool, the totals are allocated across the production processes and multiplied by relevant data from ecoinvent v.3.5 and the World Apparel and Footwear Database (WALDB) databases. The WALDB is internationally recognized and developed by Quantis in collaboration with many textile companies.
