Rangarajan TC worked to create a formal corporate sustainability program at Viawest.


Rangarajan TC spent his summer as an EDF Climate Corps fellow at Viawest, headquartered in Denver. A major collocation provider with nearly two dozen data centers across five states, Viawest engaged TC to create a formal “green” program for the company to better manage its corporate sustainability initiatives.


TC worked with marketing, operations and sales to come up with a comprehensive structure that covered the areas of recycling, water efficiency, employee engagement and energy efficiency. TC also recommended individual programs and tactical projects under this structure, such as corporate wide electronic and cardboard recycling program, PUE (Power Usage Effectiveness) reduction targets, formation of a “green task force,” energy efficiency financing and lighting maintenance projects.

Potential Impact

These projects could help Viawest recycle approximately 75 metric tons of computers and cardboard and save 7 million kWh in energy every year, which translates to 4,400 metric tons of CO2 emissions reductions and half a million in cost savings. Above all, Viawest could use this formal green structure to identify and evaluate individual energy efficiency projects and aid continuous improvement of its corporate citizenship.
