IT is a major contributor towards to environmentally damaging CO2 emissions but the industry has an opportunity to reduce this contribution, according to a report from public sector IT management association Socitm.
In its Green IT report, Socitm said action must be taken on the reduction of waste from desktops and datacentres, best practices on flexible working should be introduced, and equipment lifecycle management strategies implemented.
It said IT accounts for 2% of global CO2 emissions, which is as much as the airline industry.
"However, ICT also has significant potential to reduce its own environmental impact from equipment manufacture, use of electricity and so on, as well as helping organisations become greener though adoption of practices like flexible working and increased efficiencies in business processes," said the report.
Socitm recommended reducing carbon emissions from the datacentre through consolidating and virtualising servers, redesign the server room to optimise airflow for cooling, checking server running temperature tolerances and adjust ambient temperatures if necessary and, consider combining heat and power (CHP) installations when planning new accommodation
It also suggested companies take action to reduce printing and paper use, provide Wi-Fi in committee rooms and offer home-workers energy efficiency advice.
