A system and method permits the selection of services from multiple cloud vendors. The system receives parameters relating to a plurality of services offered by a plurality of vendors in a plurality of cloud computing environments. The parameters relate to an actual cost charged by each of the vendors and a cost relating to an environmental impact of each of the vendors. The system calculates a value for each of the vendors as a function of the received parameters, and selects one or more vendors as a function of the calculated value. The system outputs to a display device one or more of the selected vendors and the calculated values for each of the vendors. In another embodiment, the system establishes a communication connection with one or more of the cloud computing environments, and invokes one or more applications or services from the one or more cloud computing environments.
