What we do
Practical, credible sustainability.
Grounded in data, delivered by people.
We help organisations make meaningful sustainability progress by connecting measurement, decision-making, delivery and communication.
Some clients start with carbon. Others with B Corp, ESG or reporting.
The value comes from how it all fits together.
Our model
Take stock
Measure what matters
Take action
Turn insights into decisions
Tell your story
Communicate progress with credibility
Deliver impact
Embed sustainability into how you operate
Every service below applies one or more of these pillars.
Most organisations start in one place - and build from there.
Carbon Measurement
Pillars in play: Take Stock → Take Action
Carbon footprints that stand up to scrutiny - and support real decisions
We deliver full-scope greenhouse gas (GHG) footprints designed to be used, not just reported.
Our carbon measurement work is aligned with recognised standards, including ISO 14064, and supports compliance, internal decision-making, and credible external reporting.
What we deliver
-
Scope 1, 2 and relevant Scope 3 emissions
-
Organisational and activity-based footprints
-
Complex, multi-site and international operations
-
Clear documentation and transparent assumptions
Case study
Gravity Media
Full-scope carbon measurement across a complex, international organisation, producing an audit-ready baseline and clear insight into emissions hotspots.
Our approach
We combine structured data collection through our platform with hands-on consultancy support.
That means better data quality, clearer interpretation, and outputs teams can trust.
Client perspective
Save the Children
“ZeroBees gave us confidence in our carbon data. The process was rigorous, transparent, and genuinely useful for decision-making — not just reporting.”
Carbon Reduction Roadmaps
Pillars in play: Take Action → Deliver Impact
Turning carbon data into clear, prioritised action
Measurement alone doesn’t reduce emissions. We help organisations decide what to do next, and in what order.
Our reduction roadmaps translate data into practical, proportionate action — balancing impact, feasibility, cost and organisational reality.
What we deliver
-
Emissions hotspot analysis
-
Abatement options and trade-offs
-
Prioritised short-, medium- and long-term actions
-
Support with target-setting where appropriate
Case study
Save the Children
Using carbon insights to identify priority reduction areas and support clearer internal decision-making.
Our approach
We’re honest about uncertainty.
Rather than waiting for perfect information, we help teams decide where precision matters, where direction is enough, and what can be improved over time.
Client perspective
Save the Children
“The roadmap helped us move from data to action. It gave us clarity on priorities and confidence that we were focusing on the right things.”
B Corp Certification & Recertification
Pillars in play: Deliver Impact → Tell Your Story
B Corp support focused on substance, not score-chasing
We support organisations through B Corp certification and recertification with a focus on real impact, not just points.
Our role is to help you understand what the standards are asking — and how they connect to governance, culture and day-to-day operations.
What we support
-
First-time B Corp certification
-
Recertification under evolving standards
-
Gap analysis and action planning
-
Evidence preparation and submission support
How we add value
We’ll tell you when something isn’t worth the effort — and where it genuinely strengthens your organisation. That honesty is central to building a credible B Corp journey.
Client perspective
Otiumberg
“ZeroBees challenged us in the right ways. Their support kept the focus on substance and integrity, not box-ticking.”
ESG & Sustainability Strategy
Pillars in play: Deliver Impact → Take Stock
Sustainability strategy grounded in what’s material and proportionate
Not every organisation starts with carbon — and not every sustainability challenge can be solved through emissions data alone.
We support broader ESG and sustainability strategy where organisations need structure, prioritisation, and credible evidence for stakeholders.
Our work includes
-
ESG diagnostics and materiality assessments
-
Governance, policy and framework development
-
Strategic sustainability planning
-
Preparing for increasing regulatory and stakeholder expectations
Case studies
-
The Good Net — Supporting the development of a structured sustainability approach aligned with organisational values and delivery.
-
Royal Academy of Engineering — Contributing to sustainability and impact frameworks at an institutional level.
Sustainability Communications
Pillars in play: Tell Your Story → Take Stock
Clear, credible sustainability storytelling — backed by evidence
Good sustainability work deserves clear communication. Poor communication can undermine even genuine progress.
We help organisations communicate honestly and confidently, ensuring claims are grounded in data and aligned with reality.
What we support
-
Sustainability and impact reporting
-
Website and brand sustainability content
-
Stakeholder communications
-
Avoiding greenwashing and over-claiming
Case studies
-
Under Her Eyes — Shaping sustainability communications aligned with brand, values and evidence.
-
