This means taking a fresh look at lifecycle management to find ways to minimise the impact of IT on the environment. IT heads must also put pressure on IT suppliers to employ green practices.

“CIOs need to ask suppliers and service providers about their activities to reduce greenhouse emissions and their broader environmental policies,” says Rakesh Kumar, research vice-president at Gartner.
