It is widely cited that the IT industry is currently responsible for the same level of carbon emissions as the aviation industry, and experts predict that these emissions will actually double in the next few years. There is a common consensus across all industry sectors that organisations have a responsibility to cut their carbon dioxide emissions if the effects of climate change are to be addressed. In fact, recent legislation makes it mandatory for organisations to do so. The book provides a fundamental understanding of the importance of IT in achieving an organisation's green objectives. It gives the tools to create an action list to identify and address Green IT requirements. The book is primarily aimed at IT service providers but also contains advice, hints and tips for the general IT user.
