This document is the result of recent developments by the textiles and fashion industry to create a material standard for leather, similar to those that exist for down and wool. Experience shows that at the rate that certified virgin material becomes available, the questions about the viability – economically, ecologically, and in terms of quality – of recycled materials start to emerge. With this report Air Coop and the EOG would like to give those interested in the topic a head start by providing qualified information about the current situation, as well as ongoing developments in this area. And in this way encourage brands, designers and manufacturers to experiment further and push the boundaries of current practice.
