Helping your team deliver sustainability with confidence
Practical carbon and energy advisory to strengthen capability, support decision-making
and make real progress on your sustainability goals.
Led by advisors with 40+ years’ combined experience — from clean energy transition research at the University of Oxford to real-world delivery.
A different approach to sustainability support
A simple, ongoing advisory subscription — giving you direct access to experienced, senior advisors without the need for repeated consultancy projects.
You are not buying a report or a one-off project.
You are gaining direct access to experienced advisors who support your team throughout the year — helping you navigate energy and carbon reporting, compliance, implementation and communication decisions as they arise.
What this replaces
Repeated consultancy projects
Disconnected sustainability work
Reports that don’t translate into action
Instead, you get ongoing, practical support that helps your team move forward with confidence.
Many organisations find that when sustainability is owned internally, it becomes a source of pride and engagement — not just a reporting requirement.
What you get
Direct access to Dr. Russell Layberry & Catherine Bottrill
Monthly calls, with additional support available as needed.
Email and ad hoc support when needed
Review of data, reports and contractor proposals
Practical advice on energy, carbon and sustainability decisions
Templates and tools to support internal delivery
Who you’ll be working with
40+ years’ combined experience across energy, carbon and sustainability
400+ energy audits across commercial and cultural buildings
Background spanning Oxford, Yale, and real-world delivery
Experience across strategy, policy, systems and implementation
Who this is for
This service supports teams across your organisation — not just sustainability or the estates/facilities.
It is particularly valuable for:
Senior leadership needing confidence in sustainability and investment decisions
Facilities and operations teams managing buildings, energy and contractors
Finance teams building business cases and assessing investments
Sustainability leads coordinating reporting, compliance and delivery
HR teams supporting engagement and behaviour change
Marketing and communications teams shaping sustainability messaging
Anyone in your organisation can draw on the advisory support — whether to sense-check an idea, review work, or get guidance on next steps.
Not suited to organisations looking for one-off consultancy projects or outsourced delivery — this service is designed for teams that want to build capability and manage sustainability internally.

Why This Approach
Traditional sustainability consultancy often focuses on reports and one-off projects.

Our approach is different.

Reducing energy use and costs
Making confident, well-informed decisions
Delivering real progress on sustainability goals
