New guidelines: Tier 1 Grey Water Footprint accounting

Together with Dokuz Eylul University and University of Twente, the Water Footprint Network has released the much awaited guideline document on accounting the grey water footprint.

The Grey Water Footprint accounting: Tier 1 supporting guidelines is the outcome of a very intense collaborative and iterative process with inputs from WFN’s partners and experts in this field lasting for more than a year. It provides detailed guidelines and suggests the most appropriate default data sets to be used where field data are limited due to time and resource constraints.
