Recompute every disclosed GHG figure. To the gram.

A limited-assurance workbench. It independently re-derives each reported emissions figure from activity data × a cited, versioned emission factor, runs a ±5% tolerance test, and assigns Pass · Exception · Cannot-Verify. The deterministic engine decides; a fenced template only phrases the conclusion. Swap the grid-factor vintage and watch a metric cross the modified-opinion line, proof it handles the judgement-heavy part instead of assuming it away.

synthetic data Helios Manufacturing SE · FY2025 · 20 disclosed metrics · runs entirely in your browser, no network.

Grid emission-factor vintage (Scope 2)

Scope-3 purchased-goods method

Cannot-Verify remediation

One metric is disclosed with no cited factor. Until evidence is supplied it cannot be verified.
