This paper explores the intersection of responsibility, structural injustices, and business behavior in the context of low-carbon transition and climate change mitigation. Focused on the determi-nants of business strategic responses to structural injustices, our conceptual model emphasizes the intricate interplay between stakeholder power and evolving normative frames of efficiency and legitimacy in the sustainability discourse. We highlight that businesses' perception of stakeholder power significantly influences their re-sponse to responsibility in the absence of direct causality for harm. The model elucidates the mechanisms shaping corporate decision-making, revealing variations in business responses based on the anticipated influence of different stakeholders. Importantly, our research addresses the empowerment of traditionally marginalized stakeholders in the changing landscape of sustainability, particularly in the context of a just transition. By bridging the gap between theoretical constructs and practical business conduct, our conceptu-al model provides a critical link for advancing responsible climate mitigation innovations and encouraging tangible changes in business behavior towards a more sustainable future.
