ICT environmental managers know the green ICT legal framework, understand the role of the ICT network configurations in the economy and energy resources deployment and evaluate the impact of CO2 footprint of each ICT resource in the organisation's network. They plan and manage the implementation of environmental strategies for ICT networks and systems by conducting applied research, developing organisational policy, and devising strategies to meet sustainability targets. They ensure that the whole organisation uses ICT resources in a way that is as friendly as possible for the environment.
