Current approaches for reducing the environmental impact of IT are typically generic in nature and rarely take into account the actual functionality offered by services. To develop more powerful, service-specific strategies for reducing the carbon footprint of IT, more complete and widely-understandable specifications of services are needed that describe exactly what a service does, to what level of quality and with what environmental consequences. Such Green Specifications make it possible for more stakeholders involved in the delivery and consumption of IT services to understand their detailed functionality as well as the tradeoffs between Quality-of-Service (QoS) and environmental impact entailed in their use. This not only increases the opportunities for optimizing the delivery of services, it also provides the foundation for new business models to encourage users to make greener consumption choices. In this paper we introduce the concept of Green Specifications, illustrate what they might look like through a small example and discuss how they can be used to reduce the environmental impact of IT.
