Some industry commentators have stated that ITIL Version 3 missed an opportunity in not addressing one of today's biggest challenges - sustainability. This publication addresses that challenge and shows how organisations can use service management to reduce the environmental impact of IT as well as reducing costs at the same time. Whilst most organisations are addressing the environmental impact of IT through data centre consolidation, virtualisation, cloud computing and so on, the ones having the biggest impact are those realising that it is improvement in workflow and processes that will have the greatest impact. There is no need for a new methodology or framework for sustainability. Service management and best practice guidance such as ITIL can address today's environmental challenges. This book shows you how.
