The eight case studies reveal a diversity of environmental impacts at various stages of the products' life cycle. The purchase of remanufactured ink cartridges by the French Ministry of Education has led to a decrease in the amount of waste generated at the manufacturing stage. The construction or services case studies (Yorkshire and Humber Region, UK, and Oregon, USA) demonstrate significant impacts related to the reduction of CO2 emissions, of waste production, and of water consumption. The Ferrara study (Italy) and the recycled paper case (São Paulo, Brazil) show positive environmental effects.
