What organization has developed a consensus definition of 'Water Neutrality'?

To encourage water conservation and effective use, the government's think tank NITI Aayog has established a common definition and method for water neutrality in industries. The total freshwater consumption, including direct and indirect water use in crucial supply chains, will be referred to as "water neutrality," and it will be required to be equal to or lower than the quantifiable water savings realized through strategies to increase water use efficiency and conservation efforts.
