Rowe said Australia was likely to have tighter legislation in Australia for Green IT in the future, particularly around e-waste. Increased energy prices, however, is also likely to have an impact on organisational Green IT strategies.

"I think the price in the market will be what really stimulates investment and creates a stronger business case for the next level of usage, apart from quick wins," she said.

As part of the research, Fujitsu asked organisations whether they employed metrics within the office environment for measuring carbon emissions -- for example, how they measure and monitor the ratio of the energy bill that comes from IT. Organisations are also asked about metrics in the data centre.

"We think [metrics] are fundamental to be able to strengthen the business case," Rowe said. "Most countries are doing reasonably well at the quick wins approach but if you are going to build a business case, it is fundamental to have a baseline that you can go back and measure savings against."
