Your Fractional Commercial Sustainability Director
I help B2B SMEs make sustainability commercially viable.
Winning and retaining contracts, responding to client and market demands and building sustainability into how you operate.
“Gavin combines commercial thinking with practical sustainability expertise. He focuses on what sustainability means in real business terms rather than theory or ESG reporting.”
-Nick Payne, MD, SA Brain
“What really sets Gavin apart is how well he gets both the sustainability world and the commercial one”.
-Group Managing Director, Retail Marketing & Logistics Company
"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”.

RECENT WORK IN PRACTICE
The work takes different forms: fractional leadership, practical projects, workshops and capability building.
FRACTIONAL ROLE · 18 MONTHS
Retail marketing services business
Working within the agency to strengthen its ESG credibility and response to client tenders and RFPs across FMCG, food and beverage, tobacco and confectionery.
This included ESG audits linked to key client accounts, alongside development of a clear sustainability strategy, plan and measured pathway for the business.
STRATEGY

Sustainability strategy and a practical pathway for the leadership team.
CAPABILITY BUILDING

PRACTICAL ACTION
Carbon, cost & operational priorities + risk assessments
Carbon footprint audits and practical initiatives to reduce energy use, waste and cost + sustainability reviews and materiality assessments.
Business First
Before talking about sustainability in isolation, I start by understanding your business.
Where do you make money?
Where is margin being lost?
What is your proposition?
What do your customers value?
How do you compare with competitors?
What are the barriers to growth?
Where are the operational constraints?
Always applying a sustainability lens to identify the risks, opportunities and priorities that matter commercially.
How I Work
I help B2B SMEs respond to the commercial demands of sustainability and build it into how they operate.
The support can range from a focused workshop or training session to ongoing fractional leadership.
Commercial challenges
I work with businesses dealing with issues such as:
Winning and retaining contracts and tenders
Responding to customer and client sustainability demands
Understanding supply-chain requirements
Developing sustainable products and propositions
Carbon, Scope 3 and sustainability data
Cost, energy and resource efficiency
Climate and sustainability risk
Marketing, communications and greenwashing
Understanding what sustainability means for the way you operate
How I Support You
Commercial Workshops
Focused sessions to explore a specific business or sustainability challenge.
Training
Building the knowledge and skills your people need to understand the issues and act on them.
Advisory
Practical support to develop priorities, plans and actions.
Fractional support
Ongoing commercial sustainability leadership when you need more than a one-off intervention. This might be a day a week, several days a month or a more substantial part-time role, depending on what the business needs.
