Circular economy (CE) and green building (GB) are playing increasingly prominent roles in operationalising the Sustainable Development Goals (SDGs) within the built environment, including in rapidly urbanising Global South contexts such as India. Although often assumed to be complementary, their integration remains insufficiently examined, particularly in terms of their structural alignment and divergence. This study investigates the synergies and structural divergences between CE and GB through an empirical and analytical approach grounded in the Indian built environment sector. Qualitative data were collected from a multi-stakeholder participatory workshop with built environment practitioners in India and through follow-up interviews and analysed using qualitative content analysis to identify patterns in how these approaches are interpreted and applied in a participatory setting. The findings indicate that GB predominantly engages SDGs through performance-oriented, asset-level interventions, while CE operates through system-level strategies focused on material circulation and value-chain transformation. Although areas of convergence are evident, particularly in relation to SDGs 11 and 12, important structural divergences emerge across three key dimensions: scale, temporality, and underlying mental models. These divergences influence how sustainability interventions are framed and implemented with SDG targets. The alignment of CE and GB requires systemic reforms that incorporate circularity criteria within building rating systems, align CE and GB within unified regulatory and procurement frameworks, and embed systems thinking and life cycle approaches within professional education to translate CE from a conceptual framework into an operational paradigm in the built environment.
