Well one link deeper says "Restrict the export of textile waste" but I'm still unclear why they preferred these measure over a carbon tax.
Edit: "To prevent unintended negative consequences for circular business models that
involve the sale of products after their preparation for reuse, it should be possible to
destroy unsold consumer products that were made available on the market following
operations carried out by waste treatment operators in accordance with Directive
2008/98/EC of the European Parliament and of the Council3. In accordance with that
Directive, for waste to cease to be waste, a market or demand must exist for the
recovered product. In the absence of such a market, it should therefore be possible to
destroy the product." This is a rather interesting paragraph which seems to imply you can destroy clothes if truly nobody wants it.
