THE COMMERCIAL & SUSTAINABILITY CAPABILITY GAP
Commercial performance and sustainability are no longer separate disciplines. The businesses that thrive are the ones that develop both together.
Most companies have commercial capability. Many are developing sustainability capability. Very few integrate the two.
That's the gap.
I help businesses close it by building:
Commercial Capability. P&L • Profitability • Growth • Markets • Customers • Commercial Strategy
AND
Sustainability Capability. Responsible Business • ESG • Risk • Regulation • Supply Chains • Net Zero
Build both together and your business is better equipped to compete, win customers, improve performance and create long-term value.
SOME CLIENT TESTIMONIALS
“Gavin combines commercial thinking with practical sustainability expertise. He focuses on what sustainability means in real business terms rather than theory or ESG reporting.
He provided clear, actionable advice and a coaching style that helped us rethink how we approached the challenges we were facing. He also delivered a written strategy document that gave us a practical foundation and pathway for moving forward.
It was a strong mix of commercial clarity, practical sustainability insight and hands-on support.” May 2026
-Nick Payne, Managing Director SA Brain
“What really sets Gavin apart is how well he gets both the sustainability world and the commercial one. That mix meant we ended up with a strategy that wasn’t just ‘nice to have’ but something people could get behind and deliver. He brought our teams along for the ride and helped us talk to clients about it in a way that felt honest, inspiring, and practical.
He made a big difference to our journey. I’m really glad we had him on board and I wouldn’t hesitate to recommend him to anyone looking to do sustainability properly." November 2024
-Group Managing Director, Retail Marketing & Logistics Company
“Gavin consistently demonstrated an exceptional ability to engage audiences, from CEOs and senior directors to junior colleagues. His commercial leadership and deep ESG knowledge enabled teams to build practical capability that translated into meaningful outcomes.
He played a pivotal role in strengthening Acosta’s ESG credibility and retaining key clients. His impact as a commercial ESG professional is both lasting and measurable”.
-Michelle Carter, Interim Head of HR Acosta Europe
"Gavin facilitated a full-day sustainability session for a room of people from the same sector but with very different commercial priorities. He managed something genuinely difficult - bridging real commercial pressures with genuine sustainability ambition, without making either feel like a compromise.
His candour, warmth and depth of experience created an environment where people felt comfortable being honest and had their thinking genuinely challenged. Lively, enjoyable and substantive - a rare combination.
If you're looking for a facilitator who can hold a complex room and leave people energised, I'd recommend Gavin without hesitation."
-Cheryl Chung, Corporate & Government Affairs
"We had a brilliant workshop with Gavin – lots of fantastic insights and a whole new perspective on sustainability and marketing in a sustainable world."
-German National Tourist Board
"Gavin is consistently helpful, knowledgeable, and a pleasure to work with. He's helped us to get started with clarity about sustainability and what this means in practice, well beyond carbon footprints. Thought-partnership in these early stages has been invaluable."
-Saskie Dorman, NHS Palliative Care Consultant, Forest Holme NHS Hospice
“We would like to thank Gavin Miller for his time with the Climate Partnership Steering Group. He has had a brilliant and useful impact on business interactions and the Climate Strategy.”
-RBWM Climate Partnership Committee Chair
