Dressing well with a clear conscience: When shopping online, customers are increasingly paying attention to whether products are fair and sustainable. However, it is not always easy to recognize this, there is often a lack of clarity and transparency when it comes to certification, labels and other sustainability claims. A consortium of research and industry partners has been looking for solutions in the ZuSiNa project ("Besserer Zugang und Sichtbarkeit von Nachhaltigkeitsinformationen im Online-Handel", Better access and visibility of sustainability information in online retail). In an online guide, Fraunhofer ISI, Fraunhofer IAO, ConPolicy and the German Research Center for Artificial Intelligence (DFKI) present their results and provide technical and AI-based solutions.
