Calculation

Intake Sustainability Ratio
=	Sustainable Water Intake Ratio + Sustainable Energy Intake Ratio + Sustainable Material Intake Ratio   × 100% 3

where

• Sustainable Water Intake Ratio = Sustainable water intake as a percentage of total water intake
• Sustainable Energy Intake Ratio = Recovered resources as a percentage of total resources used
• Sustainable Material Intake Ratio = Resources sustainably disposed as a percentage of total resources disposed

Unit of measure: %
