John Higgins, director general of Intellect, said there are four main areas where businesses need education, including what green criteria IT managers should specify in a request for purchase when buying equipment.
"Investment in new technologies will be crucial to building the low carbon economy of the future. Across all sectors of the economy, we will need to harness the power of technology to reduce greenhouse gas emissions," said Andrew Sentance, a part-time professorial fellow based at the Centre for the Study of Globalisation and Regionalisation at the University of Warwick.
But getting IT managers to go green could be a problem, as Forrester analyst Phil Sayer said that 22% of IT managers still have no plans to go green.
"A further 39% of IT managers said that they had no plans, but were considering going green. IT managers have performance concerns over using green equipment and designated green compliance officers are still not mandatory in companies."
Forrester surveyed 130 IT managers in 2007.
