Fractional Sustainability Consultant
Your first serious ESG question just landed. Let's make sure you can answer it.
I work with climate tech founders and early-stage SMEs at the exact moment sustainability stops being theoretical. Fractional, embedded, and out before you need a full-time hire.
ESG gets treated like a glossy annual exercise. It's actually the most honest form of risk management a business can do.
Who I work with
Clients
Climate & sustainability startups
You have a strong mission and early traction. A client or investor just asked a question you can't yet answer with data.
Ops-light founding teams
You're 2-5 people. Sustainability is everyone's job and no one's job. You need someone who can own it without hand-holding.
SMEs entering regulated markets
A tender, a supplier questionnaire, or a new market is asking for ESG credentials you haven't built yet.

Selected Work
Projects
Climate · Circular Economy · Early Stage
Resting Reef
A world-class product with no data to prove it. I built the evidential foundation from scratch.
Sustainability Services
EcoVerify
SMEs losing contracts because they couldn't evidence their sustainability. I joined as first hire and built the system to fix that.
Built Environment
Concentric Solutions
A consultancy that knew ESG mattered but had no data, no baseline, and no idea where to start. I took them from blank page to first sustainability report.
Testimonials
What clients say
"Jack demonstrates a level of wisdom and maturity far beyond his years. He is a clear-thinking, ambitious leader with a genuine thirst for knowledge. He naturally connects with people, thrives when given responsibility, and consistently sees projects through to successful completion – motivated by the desire to do excellent work and make a meaningful impact."
Steve Bland
EcoVerify
"Jack has been a pleasure to work with. His contribution to the team on recent ESG projects has been exceptional. He is clearly passionate about his subject and brings a depth of understanding that has significantly advanced our internal initiatives around ESG Reporting. His approach has been practical and collaborative, with an attention to detail and proactivity that has meant we could rely on him to drive workstreams of activity independently, and have confidence in the result. The team at Concentric look forward to working with him further, and wholeheartedly endorse his professional approach."
