Independent verification confirms CBOM calculates greenhouse gas emissions in compliance with ISO 14064-1:2018 — with zero non-conformities.

London, UK — 26 June 2026 — Clear Decisions, the SaaS platform helping data-centre operators turn compliance into a competitive advantage, today announced that the carbon engine inside its CBOM platform has been independently verified against ISO 14064-1:2018, the international standard for the quantification and reporting of greenhouse gas (GHG) emissions and removals.

Following an assessment by independent verification body Interface NRM Ltd, Clear Decisions has been issued a Certificate of Verification (No. C9082), confirming that CBOM “operates a compliant Greenhouse Gas Quantification model … in line with ISO 14064-1.” The tool was “assessed and found compliant for appropriate methodologies, quantification and associated reports,” with zero non-conformities identified. CBOM now carries Interface NRM’s “ISO 14064-1 Verified Tool” mark.

This makes CBOM the first AI-powered carbon tool to be independently verified to ISO 14064-1 — giving data-centre operators a defensible, standards-aligned basis for measuring and reporting their carbon footprint.

“Carbon claims are only as good as the methodology behind them. For data-centre operators facing the EED, CSRD and the EU Taxonomy, ‘trust us’ is no longer good enough — the numbers have to withstand independent scrutiny,” said Louisa Cilenti, Chief Legal Officer at Clear Decisions. “This certificate means our customers aren’t reporting estimates dressed up as facts. They’re reporting figures calculated on a model independently verified to ISO 14064-1, with a full audit trail behind every number. That is exactly the assurance the market — and the regulator — now demands, and we’re proud that CBOM is the first AI product to bring it to the data-centre sector.”

What was assessed

Interface NRM’s agreed-upon procedures (ISO 14064-3 Annex C) examined the full carbon engine, not just its outputs. The scope covered:

  • GHG calculation methodologies and the calculation engine itself.
  • Emission-factor application and mapping against recognised data sources.
  • Activity-data processing, aggregation, unit conversions and rounding logic.
  • Boundary and categorisation across Scope 1, Scope 2 and Scope 3 emissions.
  • Audit trail, version management and record retention controls.
  • Reporting outputs and export functionality, checked for consistency with source data.

The verifier conducted a process-based review including methodology and architecture review, sample-based recalculation of selected emissions outputs, interviews with the development team, and testing against representative datasets.

What this means for data-centre operators

Carbon numbers you can defend
Every emissions figure CBOM produces is calculated on a methodology independently verified to ISO 14064-1:2018 — so the output stands up to auditors, investors and regulators, not just internal review.
Scope 1, 2 and 3 in one engine
The assessment covered direct, indirect and value-chain emissions, giving operators a single verified basis for full-inventory reporting.
Audit-ready by design
Calculation logic, emission-factor mapping, audit trails and reporting outputs were all in scope — every figure is traceable to its source.
Built for data centres
A GHG engine verified to the international carbon-accounting standard, purpose-built for the data centre sector rather than retrofitted from generic corporate tooling.

Scope of the verification

The Certificate of Verification (No. C9082) was issued by Interface NRM Ltd following an agreed-upon procedures assessment of the CBOM carbon accounting tool against ISO 14064-1:2018 (procedures per ISO 14064-3 Annex C). The responsible party for the design, operation and methodology of the tool is The Clear Decision Company Ltd. The certificate confirms the compliance of CBOM’s GHG quantification methodology with ISO 14064-1; it is not a verification of any individual organisation’s emissions inventory, which remains subject to that organisation’s own data and assumptions.
