This letter has been sent to the European Commission by civil society groups to express concern regarding the application of the ‘Product Environmental Footprint’ (PEF) method to apparel and footwear products. The letter calls for the PEF ‘category rules’ for apparel and footwear not to be used as the standalone method behind any future textile product labelling scheme, for substantiating green claims made in marketing, or in any other EU policy measures.
