Background/Context: The objective of achieving higher sustainability in our lifestyles by information and communication technology has lead to a plethora of research activities in related fields. Consequently, Software Engineering for Sustainability (SE4S) has developed as an active area of research. Objective/Aim: Though SE4S gained much attention over the past few years and has resulted in a number of contributions, there is only one rigorous survey of the field. We follow up on this systematic mapping study from 2012 with a more in-depth overview of the status of research, as most work has been conducted in the last 4 years. Method: The applied method is a systematic mapping study through which we investigate which contributions were made, which knowledge areas are most explored, and which research type facets have been used, to distill a common understanding of the state-of-the-art in SE4S. Results: We contribute an overview of current research topics and trends, and their distribution according to the research type facet and the application domains. Furthermore, we aggregate the topics into clusters and list proposed and used methods, frameworks, and tools. Conclusion: The research map shows that impact currently is limited to few knowledge areas and there is need for a future roadmap to fill the gaps.
