The pathway
How you actually get there, here
How you become one varies far more by country than what one does. This is the UK route. Most people take one of these ways in; the right one depends on where you're starting from.
- 1
Principal, Corporate Sustainability Transformation (L5)
3-5 yearsSkills to master
- At the Principal level, you'd have already owned a major pillar of sustainability strategy (e.g., Decarbonisation) and influenced senior leaders. To step up to Director, you'd need to broaden your scope to an entire business unit or enterprise, manage a larger portfolio of programmes, and take on more direct team leadership.
You're ready to move on when
- Successfully led multiple complex, cross-functional programmes to completion.
- Demonstrated ability to influence executive leadership on strategic sustainability decisions.
- Built and mentored a high-performing team of managers and specialists.
- Consistently delivered measurable impact against challenging ESG targets.

Head of Sustainability / ESG (mid-sized organisation)
4-6 yearsSkills to master
- If you're coming from a smaller or mid-sized company where you were the 'Head of' the entire sustainability function, you'd need to adapt to our larger scale, more complex stakeholder landscape, and potentially more formal governance structures. It's about scaling your leadership and strategic thinking.
You're ready to move on when
- Experience operating at a strategic level within a smaller organisation, owning the full ESG agenda.
- Proven ability to build a sustainability function from the ground up or significantly mature an existing one.
- Comfortable presenting to and influencing a Board of Directors.
- A clear understanding of the challenges and opportunities of scaling sustainability initiatives in a larger, more complex environment.

Senior Sustainability Consultant (top-tier firm)
5-7 yearsSkills to master
- Coming from consulting, you'll have a strong grasp of frameworks and strategy. The leap to Director here means moving from advising to owning the execution, managing large internal teams, and navigating internal politics for sustained change. It's about getting your hands dirty with implementation and living with the consequences.
You're ready to move on when
- Led major sustainability strategy engagements for large corporate clients.
- Deep expertise in multiple ESG domains and reporting standards.
- Strong client relationship management skills, transferable to internal stakeholder engagement.
- A clear desire and demonstrable aptitude for driving internal transformation and building internal capabilities, not just providing recommendations.
