Principle 13: Supervisors should determine that banks' incorporation of material climate-related financial risks into their business strategies, corporate governance and internal control frameworks is sound and comprehensive. [Reference principles: BCP 9, BCP 14, BCP 26, SRP 20]

49. Supervisors should determine that roles and responsibilities for climate-related financial risks, including for the board and senior management, are clearly assigned, adequate and properly documented in relevant policies, procedures and controls.

50. Supervisors should assess the effectiveness of board and senior management oversight of climate-related financial risks and should verify that board and senior management receive accurate and appropriate internal reporting on material climate-related financial risks in order to conduct this oversight.

51. Supervisors should maintain sufficiently frequent contact, as appropriate, with board and senior management to develop an understanding of, and assess the bank's long-term approach to, addressing climate-related financial risks in a forward-looking manner. Where necessary, supervisors should challenge the bank on the assumptions made in setting strategies and business models.

52. Supervisors should determine that banks consider the potential impacts of climate-related risk drivers when developing and implementing their business strategies, including addressing the resiliency of their business models to any material climate-related financial risks over various time horizons and considering how these risks may impact their ability to achieve their business objectives.
