A decision support system based on fuzzy reasoning and AHP-FPP for the ecodesign of products: Application to footwear as case study.

•An Ecodesign Index (EcoInd) is proposed to integrate the information coming from Environmental Risk Assessment and Ecological Footprint.•A decision support system (DSS) integrating the criteria provided by the environmental indicators was developed based on Fuzzy Preference Programming method and fuzzy logic reasoning.•The developed DSS is very useful to aid the ecodesign of products.•The DSS was tested with the ecodesign of footwear as case study.
