Resumo:
Many individuals and organisations have asked the Water Footprint Network for a manual that contains a complete, consistent and up-to-date overview of the method of water footprint assessment. This report offers such a manual. It covers a comprehensive set of methods for water footprint accounting. It shows how water footprints cane be calculated for individual processes and products, as well as for consumers, nations and businesses. Besides, the report includes methods for water footprint sustainability assessment and a library of water footprint response options. This manual has been prepared by the authors as requested by the Water Footprint Network and serves as the water footprint guidelines promoted by the WFN.
