AT&T and Environmental Defense Fund jointly work towards water footprint reduction

To address this challenge, AT&T and Environmental Defense Fund (EDF) joined forces. To start reducing the water used in AT&T's operations, and thus the water embedded in using our phones and network, AT&T and EDF are running cooling efficiency pilots to identify best practices in three categories: better water treatment technologies, improved operational practices and increased use of "free air" cooling. Their hope is to identify concrete ways to reduce AT&T's 3.4 billion gallon water footprint, and announce the results of their pilot in early 2013. They anticipate finding ways to save millions of gallons of water per year for AT&T, and potentially billions of gallons if the solutions are adopted by other industries. More information:
