The widespread adoption of cloud computing is having a big impact on the environment since the energy consumption of data centers and the resulting emissions are signiﬁcantly increasing. Researchers and practitioners in this ﬁeld are looking for methods to improve the energy efﬁciency of data centers and increase the use of green energy sources. In fact, besides the energy consumption, the greenness of a data center can be characterized by the quantity of CO2 emissions associated to the use of electricity (from a speciﬁc energy mix) and/or fuels (e.g. for heating or cooling). In this paper, we propose an approach in which environmental impacts are considered as an important factor for the selection of the cloud site for the deployment of applications. In detail, considering a user perspective and focusing on the assessment of energy consumption and CO2 emissions, this paper proposes a method to support the users towards greener
choices in the deployment of cloud applications.
