Having set out the legal duties of directors, officers, trustees, and investment managers in Chapter 4, this chapter discusses principles and frameworks that can inform effective climate governance. It offers advice on how to get started. It raises the notion of having climate competent directors and pension fiduciaries. Such fiduciaries may rely on engaging asset managers and engagement service firms, but they cannot delegate their fiduciary obligations. The chapter examines how boards can measure progress towards decarbonization. It examines the framework on climate governance proposed by the Taskforce on Climate-related Financial Disclosure (‘TCFD’), including disclosure of governance of climate risk, climate strategy, risk management, and metrics and targets. It examines two emerging tools—climate scenario analysis and integrated assessment models.
