The current document shares the findings of this extensive survey, with the intention to reflect the sustainability posture of the responding SNS JU research projects, their understanding and use of sustainability definitions and methodologies as well as the sustainability impact they target with their execution. Certain gaps have been identified as well as recommendations for action as a result of the analysis of the responses. The target of this work is to provide the readers with insights on how advanced 6G technology research projects tackle sustainability and what support and collaboration they might need to further advance on their sustainability impact targets.
