On-premise carbon accounting
The carbon ledger
that never leaves
your walls.
Zero-estimation emissions accounting, auditor-grade from the first entry. ClimateMCP runs inside your own infrastructure. Your data never touches our servers, because we do not have any.
The differentiator
Every carbon platform on the market asks you to trust its estimate and its cloud. We built the one that asks for neither.
ClimateMCP ingests metered and invoiced data directly, computes emissions with full calculation lineage, and stores the resulting ledger inside infrastructure you already control. Nothing is modeled. Nothing leaves the building. When an auditor asks where a number came from, you can show them the entry, the source document, and the method, in that order.
Zero estimation
Every figure traces to a metered reading or an invoice line. No industry averages standing in for your real data.
Data sovereignty
Deployed inside your own cloud tenant or your own data center. We never hold a copy of your ledger.
Auditor-grade trust
Every entry carries its source, timestamp, and calculation method, built for the audit, not bolted on after.
How it works
Three steps. One ledger. No copies.
Connect your sources
Meters, utility invoices, fuel logs, and supplier records connect directly. No manual entry, no spreadsheets passed between teams.
Compute inside your walls
ClimateMCP deploys into your own environment and runs there permanently. The calculation engine, the ledger, and the audit trail all stay on infrastructure you control.
Hand the auditor the ledger, not a slide deck
Every figure is already traceable to its source. Reporting season stops being a research project.
The comparison the pitch deck got wrong
What the rest of the market actually offers
Every platform below is a real, credible product. None of them were built to keep your data inside your own walls, and none of them were built to avoid estimation entirely. That is the gap ClimateMCP fills.

Get started
See your own data, on your own infrastructure, in one walkthrough.
No sandbox with sample data. We deploy against a real slice of your own emissions sources, so the first thing you see is your own ledger, not a demo.
