Assessing the Role of Software in Sustainability: A Survey of Industry Practices and Research Trends

The ever-increasing demand for complex software applications has turned the entire ICT resource and energy consumption into a significant environmental concern. Several research studies have concentrated on making hardware sustainable; however, the environmental aspects of software remain underexplored. This paper discusses the contribution of software to Green Computing, with a special emphasis on energy efficiency throughout the software development life cycle. The study has pointed out the guiding principles of Sustainable Software Engineering: the efficiency of energy and resources, sustainable lifecycle management, and design centered on the users. The analysis also reveals that environmental effects, such as carbon footprint and energy consumption, call for targeted software component improvements. The study also examines the hurdles in implementing green software engineering, such as legacy system challenges, regulatory issues, and economic viability. This research integrates insights from climate science, hardware optimization, and software engineering to contribute to developing eco-friendly software systems, thus charting future directions for sustainability in this field.
