More than 80% of organizations have moved green IT further up their list of priorities, although it still lags well behind issues such as security, legacy software, data quality and server consolidation.

That's according to research from the Corporate IT Forum, a user organization comprising representatives of 150 large organizations, which recently surveyed its membership to assess the interest in green computing issues within U.K. enterprises.

The survey revealed that 81% of organizations said that Green IT had moved further up the agenda compared to last year.

However, cost is seen as a crucial sticking point; there's evidence that organizations will be reluctant to implement green measures if it means that costs will rise. "As one manager said to us, "if it saves us money, we'll do it: if it doesn't we'll think twice,' -- that's a typical attitude," said Ian Campbell, speaking at the European Green IT Summit in London.

"We found that managers often struggled to present a sound business case -- that was the biggest inhibitor," he added. The survey found that for 69% of managers, cost efficiency was the key to implementing greener policies and 51% of organizations used the implementation of such policies as an opportunity to save money.

Although green IT was listed only eighth in an IT manager's priorities, Campbell pointed out that 10 or 20 years ago, it wouldn't have featured on the list at all.

The survey also looked at particular green policies adopted by enterprises. Only 12% had installed data center cooling apparatus. "It surprised us how low that figure was," admitted Campbell. More popular were 15% of organizations using who were recycling data center heating and 19% who were using some form of carbon offsetting.

Campbell said that one of the major problems faced by organizations was in measuring the impact that green policies had. "There are no accepted standards, just a range of multiple measures. We'd like to set of national and international measures adopted," adding that this sort of benchmarking would really help IT managers and CIOs push green IT further up the agenda.
