Enterprise A-Z: Headcount
Resourcing the Work Like It Matters
“Do more with less” is the unofficial motto many sustainability leaders inherit. The mandate grows. The reporting load grows. Expectations from the board, investors, customers and employees grow. The team…does not.
At some point, you are no longer being heroic. You are being structurally under‑resourced.
Why headcount is so loaded
Headcount isn’t just a number. It’s a signal of whether the organisation believes this work is central to the business or something that can be squeezed in around the edges.
You are usually holding two tensions at once:
You do need a core team that can carry strategy, coordination, data, governance and key relationships without burning out.
You cannot, and should not, try to build an empire – sustainability has to be done with the business, not instead of it.
Treating headcount as a strategic lever means being very clear what must be held centrally and what needs to be owned in the business with your support.
What headcount actually is
Headcount decisions are business decisions: they sit in the same conversations as growth bets, cost control, productivity and risk. They are made by people who have to balance many competing needs.
For your work, that usually means being explicit about:
The minimum viable core you need to deliver what you’ve been asked to do – not just today, but over the next few years.
The embedded or dotted‑line roles in functions and business units that make sustainability real in day‑to‑day decisions.
The trade‑offs of under‑resourcing – slower delivery, higher risk, compliance exposure, lost opportunity – in language your leadership already cares about.
When you can describe your team in those terms, you stop asking for “a favour” and start making a case about how the company wants to show up.
How to start
Get honest about the load. List the major things your function is currently expected to deliver (compliance, reporting, strategy, stakeholder engagement, programmes). Next to each, write who is actually doing the work now and how sustainable that is over the next 12–24 months. This is for you first – to see the reality.
Define your minimum viable core. Based on that list, sketch the smallest central team that could realistically deliver the mandate: what roles, what level, what capabilities. Be concrete about what would not get done, or what risks would rise, if you stay as you are.
Frame one headcount ask as a business decision. Choose a single role you most need next. Write a short case that links it to outcomes your leadership cares about – risk reduction, regulatory readiness, revenue, customer commitments, talent, reputation – and to the costs of not having it. Then have that conversation at a moment that fits your fiscal rhythm, not as an off‑cycle plea.
You cannot fix structural under‑resourcing overnight. But each time you name it clearly, tie it to real business consequences, and ask for specific roles that unlock specific outcomes, you move headcount out of the realm of “nice to have” and into “how we run this business responsibly.”
