Which statement correctly describes the impact of sustainability risk on discount rates?

• A. Investors require higher returns for accepting risk, increasing discount rates and lowering valuations.
• B. Higher risk leads to regulatory penalties only
• C. Sustainability risk reduces capital costs
• D. It has no impact on discount rates

Answer: (B)

Sustainability risk is a form of uncertainty that investors price into the cost of capital. When this risk is higher, investors expect higher returns to compensate for the additional uncertainty, and that shows up as a higher discount rate when valuing future cash flows. A higher discount rate reduces the present value of those cash flows, leading to lower valuations. The idea that risk only leads to regulatory penalties is too narrow; penalties may occur, but the overall effect is to increase the cost of capital through higher risk premiums, not to decrease it. Saying there’s no impact on discount rates misses how market pricing incorporates risk into required returns.
