For 2 consecutive years, the CeBIT went under the motion "Green IT"

It is not only a matter of consciously using the energy resources, but by continuous efficiency improvement of the devices and the processes in the  IT industry energy and cost saving and  at the same time the CO2 emissions reduction can be achieved
What sounds so easy here, also has its roots in making the masses aware of the threats of climate change and to stir them into change / action.
