No apologies for commenting on another survey: Green IT provides a way for businesses to be seen doing the right thing while saving money, so this bandwagon is going to keep rolling.

A survey of just over 100 IT managers and directors in large (500+ employees) Australian enterprises found that only a third are aware of their current energy usage. Without that data, it's going to be pretty hard for them to track and report on the improvements they make.

And even though carbon emissions and water use are probably the most important environmental considerations at present, fewer (32 percent) are focussing on reducing energy consumption than on the responsible disposal of old equipment (40 percent).

Curiously, 39 percent said they were concerned about the increasing cost of energy required to power IT infrastructure.

And if you think my remark about "being seen doing the right thing" was cynical, 50 percent of respondents believe tackling emissions can favorably influence corporate reputation management.

The survey was carried out during August by ACA Research for IBM Australia.
