The concepts of politics and sustainability are loaded with various, and evolving meanings and interpretations in their own terms and relationally. This Roundtable aims to reflect on the concept of power and its relationship with, and manifestation in sustainability discourses and practices. To this end, the following questions are asked: What constitutes the politics of sustainability? How does the environment and society feature in that politics? How is sustainability linked to the past and futurisms? Who has the power to define socioecological futures, and with what effects? These questions are posed here as a source of reflection from different vantage points rather than a search for ‘correct answers.
