Intended as input for the members of the German Partnership for Sustainable Textiles, GIZ has commissioned Oeko-Institute to summarize the previous findings and deepen into critical as-pects of selected tools. This work has been conducted through desk research. Where the tools or required information were not freely accessible, the providers were contacted with questions for clarification and the request to provide a demo version to gain further insights. Experiences with the tools were also gathered, e.g. comments or opinions from other companies using the tools or publications that used the respective tool.
