Greener Data Centers

The Green Initiative is a company-wide strategic program that aims to lower emissions from our commercial data centers, establish good environmental practice and discipline throughout our corporate operations, and encourage customer participation and partnership. We have completed an extensive audit of our data centers, examining all aspects of power consumption, cooling requirements, heat dispersion and overall impact on the environment. Future operational improvements will be driven by these key business and performance metrics.

Establishing an Action Plan

Our long-term environmental strategy and planning is the result of multiple assessments by leading experts in the industry, including The Green Grid. The Green Grid is an influential industry consortium representing IT manufacturers and data center providers. It addresses the issue of facility and hardware efficiency as well as standardization, ratings and regulation.
