This integrative review introduces the ‘practice barometer’ as a conceptual tool to assess and guide practice-based sustainability research in sociology and marketing. Drawing on an integrative analysis of the existing literature, we argue for the relevance of practice theory as a powerful framework for understanding sustainability, critiquing capitalism, and advancing scholarship. We outline a trans-environmental, anti-cannibal agenda for future research by combining Fraser’s theory of cannibal capitalism and Schatzki’s account of large phenomena. Positioned as a cross-disciplinary project, this agenda calls on scholars to move beyond disciplinary silos, ask deeper ontological questions, and engage in forms of scholarship that brave institutional constraints – advancing sustainability as a research practice, not merely a topic of study.
