It is often said that the majority of environmental impacts of products occur during the design stage, so efforts to make supply chains more sustainable should inevitably include the product design process. In this chapter, we put EcoDesign in the broader product design context and discuss some aspects of implementing EcoDesign in companies. We then introduce ten “Golden Principles” (10GP) of EcoDesign and provide an illustration of how they can be used to analyze and redesign a product.
