Addressing the urgency of radical decarbonization as a mitigative response to climate risk, this book explores how business can respond to the challenges of climate risk, through various transformational processes. Those processes involve cognitive transformations, organizational changes, climate risk integration into risk management practices, shifts in corporate reporting and disclosure as well as futuristic scenario-based planning beyond normal business planning cycles. Though much has already been written on corporate sustainability efforts, there is a greater need now for building mitigative capacity at the firm level, in alignment with shifting policy and regulatory regimes. Theoretical and empirical work on these areas is addressed in the novel thought experiment approach of this book.  A research agenda for future work is provided.
