For most of the last decade, sustainability roles were communications roles with a technical veneer. That has changed quickly, and the driver was not conviction. It was disclosure regulation.
What changed
Once a sustainability claim sits in a filing rather than a brochure, it acquires an audit trail, a signature and a liability. The people producing those numbers now need the same evidential discipline as a finance function, and most organisations discovered they did not have it in-house.
A number in a report that nobody can trace back to a source is not a disclosure. It is an exposure.
The capability gap
- Carbon accounting to a defensible boundary, including the hard parts of Scope 3.
- Assurance readiness — evidence trails that survive an external auditor.
- Materiality judgement, which is where most reports go wrong first.
- Operational change, because a target nobody acts on is just a sentence.
Why it certifies well
ESG is an unusually good fit for competency assessment. The work produces documentary evidence as a matter of course, which means a portfolio submission is largely a matter of selecting from what already exists rather than reconstructing it after the fact.
