There is a clear opportunity for CIOs in every country to act boldly to assess their organizations' green computing profiles and to advocate enterprise-wide goals and policies. An article in UK's Computing reports that all to often, IT departments are followers, not leaders:

The [sustainability] approaches are invariably driven by the wider organisation, and typically the board, finance, human resources and compliance functions set overall policy.  But a consequence of the top-down approach is that few IT departments have their own specific green computing policy. Just 28 per cent of technology leaders have a formal policy to ensure that IT systems become more environmentally friendly, according to a recent CIO Connect poll.
