Development and evaluation of a reference measurement model for assessing the resource and energy efficiency of software products and components—Green Software Measurement Model (GSMM)

In the past decade, research on measuring and assessing the environmental impact of software has gained significant momentum in science and industry. However, due to the large number of research groups, measurement setups, procedure models, tools, and general novelty of the research area, a comprehensive research framework has yet to be created. The literature documents several approaches from researchers and practitioners who have developed individual methods and models, along with more general ideas like the integration of software sustainability in the context of the UN Sustainable Development Goals, or science communication approaches to make the resource cost of software transparent to society. However, a reference measurement model for the energy and resource consumption of software is still missing. In this article, we jointly develop the Green Software Measurement Model (GSMM), in which we bring together the core ideas of the measurement models, setups, and methods of over 10 research groups in four countries who have done pioneering work in assessing the environmental impact of software. We briefly describe the different methods and models used by these research groups, derive the components of the GSMM from them, and then we discuss and evaluate the resulting reference model. By categorizing the existing measurement models and procedures and by providing guidelines for assimilating and tailoring existing methods, we expect this work to aid new researchers and practitioners who want to conduct measurements for their individual use cases

An investigation of green software engineering

The urgency of sustainability concerns has intensified in recent years, sounding alarm bells over the planet's condition and prompting nearly every industry and practice to reassess their contributions to the climate crisis. Software engineering is not immune to this scrutiny. Software engineering practices significantly affect the environment and may not align with sustainability goals. Although sustainability is a relatively recent focus in software engineering, it has garnered increased attention, with numerous studies addressing various concerns and practices. Green software engineering aspires to develop dependable, enduring, and sustainable software that fulfills user requirements while minimizing environmental impacts. As this green paradigm gains traction in software engineering, practitioners must incorporate sustainability considerations into future software designs. However, despite the surge in green software engineering research, a universally accepted definition and framework remain elusive. This paper outlines green software engineering by explaining its principles, challenges, and methods for measuring and evaluating software effectiveness in this context
