GOAL: REDUCE POTABLE WATER USE AT WATER-STRESSED SITES BY 2.3% ANNUALLY FROM 2010 TO 2020
In 2016, when we announced our new water goal, we committed to cut our potable water use by 2.3% annually at AEG sites located in water-stressed regions. We define “water-stressed sites” to include any sites in locations identified as having high or extremely high “overall water risk” by the World Resources Institute’s AqueductTM tool.
We are pleased to report that in 2016 we nearly met our water goal for the year, with potable water use just 1% higher than our goal. As a group, these sites have collectively saved over 46 million liters of water compared to the 2016 Base Year.
We have completed several water efficiency projects at our water-stressed sites in the last few years and these projects have resulted in conservation of potable water. At the same time, however, most our water-stressed sites have also shown significant increases in the number of events hosted. Like the trends in our GHG emissions, the progress we make in efficiency is counteracted to a certain degree by organic business growth.
Our challenge is to look for additional efficiencies and innovative ways to reduce our dependence on potable water. To push the envelope, we are continuing to look at cooling towers and irrigation systems to determine whether any additional savings can be realized. We are also hoping to make more use of recycled water, greywater, and collected rainwater where feasible.
