Introducing the Truth Carbon Group

We didn't build a platform
and hire experts.
We spent twenty years
becoming the experts.
Then we built the platform.

Four specialist companies. One founding principle.
Carbon management only has value if it is evidentially true.

Our Story

Twenty years
in the making.

"Most carbon management companies were founded in the last five years by people who recognised a market opportunity. We were founded — quietly, without fanfare — by people who recognised a problem."

In the early 2000s, as the first serious UK carbon compliance frameworks were taking shape, a small team of practitioners began working with organisations to measure, certify and reduce their greenhouse gas emissions. There was no established playbook. The tools were inadequate.

So we built what we needed.

Every product in the Truth Carbon Group exists because a Carbon Saver certification revealed it was needed. Every methodology was tested in the field before it was documented. Every tool was designed to solve a problem we had personally encountered.

Our technical team has been together since the beginning. The expertise here is not the result of a hiring round or an acquisition. It is the product of twenty years of doing the work — in the field, with real clients, under real scrutiny.

Early 2000s

Carbon Saver Limited founded. The Carbon Saver GOLD Standard is established — one of the UK's first independently verified carbon certification schemes. The Environment Agency formally assesses and approves it as equivalent to the Carbon Trust Standard.

Following years

Carbon Verification Limited incorporated. Years of certification work revealed that independent verification required structural separation — not a department, a genuinely independent company with its own governance and professional liability.

Over the years

Carbon Advisory opens its knowledge base. Technical notes and methodologies written for certification work are made freely available — consultancy-grade guidance built from real experience, not theoretical frameworks.

Now

TruthCarbon launches. Built by the people who spent twenty years on the verification side of the desk — carbon footprinting, supplier engagement and NZi KPI management, designed by practitioners who know what a verification-ready output actually needs to contain.

Why Truth Carbon Group

What makes this group
different.

01

The expertise is real

Our technical team has been together since the beginning. No one here is new to carbon. The combined practical experience of the Truth Carbon Group team exceeds that of most entire carbon consultancies.

02

The heritage is documented

Twenty years of certifications. Hundreds of independently verified GHG inventories. Government approval. Blue-chip and public sector clients. This is not a track record claimed on a website. It is evidenced in audit files.

03

The independence is structural

Carbon Verification Limited is a separate company with its own governance and professional liability. Structural independence is the only independence that means anything when a procurement officer or auditor starts asking questions.

04

The platform was built from the inside out

TruthCarbon was not designed by product managers working from market research. It was designed by the people who spent twenty years on the verification side of the table — who knew exactly where the data gaps were.

05

The knowledge is open

Carbon Advisory makes our consultancy-grade methodologies freely available — not as a loss leader, but as a statement of what this group believes. Good carbon guidance should not be locked behind expensive contracts.

06

Truth is the operating principle

Our verification function requires us to reject inventories that don't meet the standard. Our emission factors are traceable and auditable. We named this group Truth Carbon because it describes how we work — not how we market ourselves.
