“Green ICT” constitutes a new term in Informatics that describes environmentally sustainable ICT and the use of ICTs in the interest of the natural environment aiming to sustainable development. It encompasses innovative ICT tools, e- and m-services, and smart technologies in combination with green practices and green behaviour either for the ICT industrial sector or the ICT user/citizen that contributes not only to the protection and restoration of the environment but also to the enhancement of the quality of human life. Thus, “Green ICT” has become synonymous with eco-friendly technologies and software tools.
