Fifteen years of sustainability.
One platform.
CarbonTool was built by the team behind 500+ BREEAM, LEED and EDGE certifications.
We knew what the tools should do. So we created them.

The team that certified 930+ sustainable projects decided the software should be better
Built by BuildGreen, the team behind 500+ BREEAM, LEED, and EDGE certifications over 15 years. We kept seeing the same thing: sustainability managers stuck in spreadsheets, paying consultants for work software should handle, producing reports nobody could act on. We built CarbonTool to fix that.

The people who
do the work

Carbon accounting, reporting, and decarbonization should be as natural as financial reporting. Something every company does without friction, without wasted months and without dreading the process. We started CarbonTool because we believe
sustainability management deserves better tools.
Four principles that shape
every product decision
Transparent Pricing
If learning what a platform costs requires a sales call, the price is the problem. CarbonTool pricing is public. Every plan, every number, on the website. No negotiation required to understand the math.
Decisions Over Dashboards
Reporting shows where you were. Carbon management shows what needs to change. CarbonTool is structured to take organisations from raw emission data through to scenario analysis, CAPEX modelling and reduction roadmaps — outputs a CFO or board can act on.
Self-Serve by Default
Week-long onboarding and mandatory consulting retainers are a product design failure. Pathfinder guides every setup decision. Expert support is available when needed. It is not baked into the price when it is not.
Independent and Bootstrapped
No venture capital. No acquisition roadmap. The decisions we make are about what works for organisations managing real carbon data — not about what makes the platform attractive to a buyer. That is a structural difference, not a talking point.
