Risks Nobody Can Measure

Climate change is the most visible long-horizon risk we face, and the hardest to quantify. It is also only the entry point. Climate, geopolitics, AI displacement and supply chain fragmentation are arriving together. These are not one-off shocks to be weathered and forgotten. They are structural reorganisations of how economies function, how capital flows, and how value is created.

Yet inside most organisations, these risks still live in a register. A heat map. A colour. A line in the sustainability report that says the board is aware.

Why that is not enough

Corporations cannot act on risks they cannot measure. A red cell on a matrix does not tell a CFO how much enterprise value is at stake, over what horizon, or under which future. It cannot be weighed against a capital budget or a strategy. So it is noted, and it waits.

IFRS S2 now asks companies to explain how climate-related risks affect their prospects. Compliance alone will not make that explanation useful. The question a board actually needs answered is simpler and harder: what does a 2°C or 3°C regime shift do to the value of this business over the next 25 years?

The problem, stated plainly

The futures that matter most are the ones least legible to the people who control capital. They sit too far out, behave too differently from the past, and resist the tools organisations are used to. Until they are made legible, in a language boards and CFOs already trust, sustainability remains a reporting obligation instead of a strategic priority.

And the discipline is not only about carbon. Any framework robust enough to navigate a 25-year climate horizon under genuine uncertainty — mapping scenario pathways, stress-testing valuations, designing transition plans that hold under more than one future — can be applied to tariff scenarios, fragmenting supply chains, and any structural shift with a horizon long enough to model with discipline.

That is the problem I keep returning to: making the long horizon measurable, so that it can finally be managed.
