Green ICT systems provide the technological basis for organizations to adopt and implement Green ICT policies and practices. This system support can be enhanced by using the upcoming emerging technologies of Cloud computing, Web 2.0, Service Oriented Architecture and Mobile technologies. This chapter aims to incorporate these emerging technologies within Green ICT systems to help organizations be environmentally responsible. Green ICT can be considered as the adoption of an eco-friendly process by an organization in its practice of Information and Communication Technologies. The last decade, in particular, has seen profound awareness on the part of individuals as well as organizations in being environmentally aware. While automation and related computing activities continue to lead to exponential use of energy quotient, at the same time, Green ICT continues to chip away at the ‘resigned‘ views of the decision makers to environmental responsibilities. ICT operates at systems level, applications level, at the end-user level through the desktops and printers, and at the enterprise level through its data centers, servers and other infrastructure. Green ICT is all about optimization and improvement of the organizational processes without hindering its progress in the use of technology and simultaneously minimizing the organizational impact on the environment . This chapter will discuss the context provided by ICT in introducing an organization to a Green ICT system and explaining a detailed architecture and design of such a system. The issues discussed include Hardware and Software implementations, infrastructures and attitudes and policies of decision makers and how they influence global warming, including carbon emissions and the use of software applications in measuring and reporting carbon emissions.
