Scaling Up Building Water-Energy Savings

Increasing droughts and water shortages are causing companies to pay more attention to their water use. Leaders like AT&T understand that proactively engaging in water conservation—including working with suppliers—can help mitigate its risks to water stress.

In 2012, EDF and AT&T launched an effort to identify opportunities to reduce water and energy use in buildings, with a focus on cooling towers. It turns out that many buildings are sitting on big opportunities to reduce water use in their cooling towers — up to 40% — in ways that can also save money. Based on these findings, AT&T is aiming for 150 million gallons in annualized water reductions by the end of 2015.
