Many organizations attempt to implement Green ICT. Some adopt a deliberate and holistic policy, but most approach it piecemeal. The formal definition and approach to implementing Green ICT remains elusive, because most organizations are unable to properly identify what areas to address. A comprehensive and practical Green ICT framework helps overcome this problem. Measurement is important because it enables benchmarking and comparisons by quantifying the degree of implementation of Green ICT. User organizations can then be compared to each other, or to themselves over time, to determine the extent and effectiveness of their Green ICT strategies. This paper outlines a research-based yet highly practical Green Computing framework. It is based on a 4 x 5 matrix with four vertical “pillars”: Lifecycle, End User IT, Enterprise and Data Center IT, and IT as a Low-Carbon Enabler. Applied against each pillar is a five-level Capability Maturity Model metric which can be based on a detailed survey of the organization’s policies and practices in each area. The five horizontal dimensions, or “actions” are applied across the four pillars: Attitude, Policies, Practices, Technologies and Metrics.

Why Is Green Ict Important?

Green ICT is becoming an important issue for many reasons that directly affect organizations. This influence is not merely limited to being a good corporate citizen. Green ICT has the potential to positively influence the organization’s bottom line. Consider, for example, the cost of data center power. These power expenses are soaring as electricity prices go up and new server technologies pack more and more processors, which consume more and more power, into less and less space (Koomey, 2007). Data centers form an integral and vital part of an organization’s overall strategy for reducing carbon emissions. DeCoufle (2010) discusses in detail the importance of the green grid as a glue holding data centre energy efficiency together. A separate dedicated track on Green ICT at a recent conference on Data Center management (http://www.dcgtasia.com) also focused on data center emissions. Reducing the carbon emissions of a data center has the same positive value as reducing the operating expense of that data center. Therefore, the importance of Green ICT permeates all aspects of the organization.
