Freshwater is a very important natural resource, which everyday becomes scarcer and therefore urgently requires appropriate management tools to be used in an internationally consistent fashion by different stakeholders. The objective is to propose and ISO Standard on principles, requirements & guidelines for a water footprint metric of products, processes and organizations, as well as its communication. It aims at being: i) Coherent with ISO14000 series, ii) Coherent with environmental metrics such as carbon footprint, LCA (ISO14040), GHG accounting (ISO14064), iii) Coherent with environmental communication (ISO14020, ISO 14067), and iv) Consistent with existing and ongoing work of GHG protocol (same boundaries, scope, etc.).

This presentation will outline the foreseen process, starting in 2009 and planned to last 3 years, aiming at creating such an ISO Standard.
