The German Federal Ministry for Economic Cooperation and Development (BMZ) introduced a seal for ecologically and socially produced textiles: Grüner Knopf. “With Grüner Knopf we now set a high standard and show: Fair supply chains are possible. […] this is proven by all the companies that participate.” says Gerd Müller, Federal Minister for Economic Cooperation and Development. Grüner Knopf is the first state-monitored seal that combines requirements for both the manufacturing company and the product itself. 27 German companies are already certified, 26 are in the inspection process.
