The objective of the study titled "Sustainable IT Services: Assessing the Impact of Green Computing Practices" is to analyze existing literature on green computing and its effects on sustainable IT services. The aim is to identify crucial concerns and strategic areas that can enhance customer value, business value, and societal value. The paper examines sustainable IT techniques, including power management, virtualization, enhancement of cooling technology, recycling, electronic waste disposal, and optimization of the IT infrastructure to fulfill sustainability criteria. According to the authors, sustainable IT strategies are expanding the concept of sustainability beyond energy consumption and product considerations. This expansion requires the restructuring of both the IT organization as well as the overall practices in order to fully achieve the strategic advantages of green computing.
