  In this position paper we address the Software Sustainability from the IN
perspective, so that the Software Engineering (SE) community is aware of the
need to contribute towards sustainable software companies, which need to adopt
a holistic approach to sustainability considering all its dimensions (human,
economic and environmental). A series of important challenges to be considered
in the coming years are presented, in order that advances in involved SE
communities on the subject can be harmonised and used to contribute more
effectively to this field of great interest and impact on society.
