Theme & Goals

Engineering green software-intensive systems is critical in our drive towards a sustainable, smarter planet. The goal of green software engineering is to apply green principles to the design and operation of software-intensive systems. Green and self-greening software systems have tremendous potential to decrease energy consumption. Moreover, software can and should be rethought to address sustainability issues, for instance, innovative business models, new processes, and incentives. Monitoring and measuring the greenness of software is critical to the notion of sustainable software. Demonstrating improvement is paramount for users to achieve and effect change. Analysis of the sustainability of a specific software system requires software that aids developers in weighing the four dimensions of sustainability – economic, social, environmental, and technical – with their attendant trade-offs. The software engineering community must assume leadership in this important challenge. In this workshop, we explore the theme of “green software engineering for software sustainability” with the goal of creating actionable outcomes that will affect how software engineering is practiced and taught in the future to help organizations prioritize their sustainability objectives. Therefore, contributions should consider and reflect on the impact of the software engineering practices on sustainability.
