Sustainability that pays its own way.
ESG and carbon expertise built into delivery, not bolted on — practical, commercial, and ready for tomorrow's expectations.
Results you can measure.
More than two decades delivering change across global operations, with a track record of real savings, sharper efficiency, and capability that outlasts the engagement.
Change that actually lands.
Most transformation stalls in delivery. We bring the structure, governance, and financial rigour to see complex programmes through to measurable results.

Dieple: Delivering improvement, empowering people.

Dieple is the independent sustainability and transformation practice of Katherine Byam, an ACCA-qualified accountant and Fractional ESG Director. She helps organisations make their sustainability data hold up to customers, lenders, regulators and auditors, and partners with leaders who are restructuring, scaling or improving how they operate.

Two decades across finance, audit, supply chain and operations in global organisations, including a decade at British American Tobacco and leading sustainability strategy at CooperVision, connecting site data to group disclosures. The distinctive edge: finance and audit discipline, a deep operations core, and the commercial instinct to make change and sustainability pay their way.

Available as a contract resource or on fixed-fee projects, in person or remote, across the UK and the Caribbean.

Sustainability & ESG

 

Eight fixed-fee services for organisations whose sustainability data now faces customers, lenders, regulators and auditors: from Carbon Reduction Plans and green claims to SBTi, B Corp and assurance readiness, and your annual reporting run for you. Built on finance and audit discipline.

 

Based in the Caribbean? Dieple provides support for teams getting ready for ISSB, GSS+ finance and group reporting.

Business Transformation & Change

Most programmes fail on delivery, not on the idea. We bring the structure to close that gap, from evaluating costs and building the case, through delivery, to embedding change that lasts.
