Nowadays the environment plays a significant role in the way how people perceive companies and their willingness to enter a business relationship with them. That also applies to the companies’ IT – green IT is not a new concept anymore. 

Cloud Computing can help with this problem because it can make traditional datacenters more energy efficient and thereby reduce their carbon footprint. This is because traditional data centers are often provisioned to handle sporadic peak loads that can lead to low resource utilization and thereby a waste of energy. While using Cloud datacenters different workloads are able to share the same physical host and unused servers can be shut off. Through these processes it is possible that the consumption of energy is reduced (Garg 2011). 

A research by Accenture shows that small business can save up to 90% of their emission by using Cloud applications. Mid-size businesses save 60% to 90% and large corporations save at least between 30% and 60% in carbon emission by using Cloud resources (Accenture 2010).
