When to hire a fractional Chief Sustainability Officer

Most companies hire a fractional Chief Sustainability Officer when the founder or existing team can no longer own the sustainability function at executive depth. Common triggers:

  • Enterprise customers or investors are demanding ESG data you cannot produce
  • Disclosure rules apply to you and no one owns the response
  • Carbon accounting is spreadsheet-based and unauditable
  • Supply-chain sustainability requirements are flowing down to you
  • Sustainability claims need to be defensible, not marketing

  • Targets, transition plan, and capital allocation input

Fractional (ongoing)

1–3 days per week on a recurring basis. Best when you need executive judgment in the business every week, but not a full-time hire yet.

Full-time coverage for 3–9 months. Best for a vacancy, a fundraise, an M&A event, or a turnaround.

Project / advisory

Scoped engagement (10–40 hours) tied to a specific deliverable — a plan, a system, a hire, a diligence.
