Stella McCartney is a spokesperson on ethical fashion and partner of the Ethical Fashion Initiative. 

Using materials that are sourced and manufactured by carefully selected networks of suppliers, Stella McCartney products are making significant effort to monitor their supply chains. 76% of materials are sourced from Italy, with other key sourcing countries including Hungary, Spain, Portugal, China and India. They have been using EP&L (Environmental profits and losses) since 2012 which has also enabled them to significantly reduce their environmental impact every year.
