With 6,000 print users across 23 UK locations, Logica said controlling and managing printing is a key plank to achieving its green targets.

To reduce power usage and cut costs, the service provider implemented a managed print services system from HP. This has helped eliminate many personal printers and has supported the introduction of multifunction printers (MFP) that can print, copy, scan and fax through one device.

These measures have meant that printing has fallen from 16 million prints in 2006 to 9.7 million in 2011, a reduction of 65 percent. Subsequent carbon emissions related to paper have fallen from 407 tonnes in 2006 to 133 tonnes in 2011.

Arlette Anderson, UK head of health, safety and environment at Logica, said: "This has been a long-term initiative and by printing more efficiently HP has helped us realise the significant cost and business benefits that can be made. We still have a long way to go but believe we will achieve our overall 50 percent carbon reduction target."

The use of remote management and economical "sleep" and "wake-up" times for systems has also enabled Logica to achieve a 32 percent reduction in energy usage for document printing.
