About us

In 2019 the KATAG AG has sent a sustainability questionnaire to fashion brand suppliers for the first time. The answers were only published for KATAG retail partners and participating suppliers in a sustainability register.

In 2022 a comprehensive market analysis was carried out, a new concept was set up and a new tool now called the Sustainability Index was developed.

Since 2023 the Sustainability Index has been accessible to retailers and brand suppliers. The core value of our tool is the uniform structured und visualized data of attributes relating to the sustainability of brands, the saving of resources (employees, working hours) for data transfer, the overview and explanations of certificates as well as further information on sustainability.
