The government plans to introduce a quality mark later this year to help IT buyers choose suppliers with genuine carbon offsetting schemes.
"People need to be sure that when they buy an offsetting product, the emissions reductions are actually taking place. This is why we are developing this code, which will be accompanied by a quality mark for accredited products," said the minister for climate change, biodiversity and waste, Joan Ruddock.
The government code will be voluntary, meaning that IT suppliers will be able to choose whether they want to seek accreditation for some or all of their products, which could include servers, monitors and cooling systems.
The Green Grid - a consortium of IT firms seeking to lower power consumption in datacentres - has said that the development of metrics and agreed-on quality marks are key to enabling datacentre managers to make informed decisions.
"Defining and propagating best energy-efficiency practices in datacentre operation, construction and design begins with clear metrics and assurance marks," said John Tuccillo, director of the Green Grid.
