Ecodesign for Sustainable Products Regulation (ESPR) is the legal act that most strongly determines the choice of raw materials and the design of textiles placed on the European market. Horizontal measures such as durability, recyclability and recycled content have been defined for all priority product groups, and it is not surprising that textiles are one of them. While everyone agrees with the EU's vision for transition of the textile sector, the details (e.g. how to interpret durability) are intensively discussed and defined in working groups that are accused of a lack of diversity. In the presentation, we will take an in-depth look at the horizontal measures and discuss controversial examples that could impact the use of low-impact renewable materials. We will also emphasize the importance of producers and users of these materials contributing to the European Commission's public consultations and providing technical data and facts. Otherwise, the laws could be written on the basis of available and even incomplete technical data that does not reflect the full reality.
