What best describes a risk index in a sustainability reporting framework?

• A. A qualitative rating based only on perception of risk by managers.
• B. A measure of market share and profitability.
• C. A single score that combines probability and consequence to prioritize mitigations and communicate risk levels to stakeholders.
• D. A financial metric that replaces all other risk assessments.

Answer: (C)

In sustainability risk management, a risk index is a single composite score that blends the likelihood of an event with its potential impact. This combination produces a priority ranking: higher scores point to risks needing attention and mitigations, and the score also provides a straightforward way to communicate risk levels to stakeholders.

This approach is not just a manager’s gut feeling or qualitative perception, and it’s not a market or profitability metric. It also isn’t a financial metric intended to replace all other risk assessments. By integrating probability and consequence into one measure, the organization can focus resources on the most significant risks and present a clear, comparable signal about overall risk exposure.
