At the request of three NGOs, the Dutch Bont voor Dieren, the Belgian GAIA and the Italian LAV, in 2010 CE Delft carried out a study comparing the environmental impact of 1 kg of mink fur with that of 1 kg of other textiles, including wool, cotton and polyester. However, a need was felt to compare fur goods with a faux fur variant, too, and CE Delft has now conducted a life cycle assessment study comparing natural fur coats and faux fur coats and natural fur collars and faux fur collars. A range of scenarios for product lifetime and maintenance were examined.
