Your emissions number is the easy part. Getting it through an ISO 14064-3 / ISAE 3410 engagement is where most teams stall. Verification Readiness turns your completed inventory into a verifier-ready evidence package — and gives the verifier you choose secure access to it.
Built around ISO 14064-3 / ISAE 3410 — you stay in control of your data and your verifier.
They calculate your emissions and hand you a report. Then the verifier asks for evidence, boundaries, a management assertion, an audit trail — and the real work starts from scratch, on a deadline.
Scope 1 and 2 totals in a report. Accurate — but unsupported.
Evidence, controls and the assertion are left entirely to you.
Governance, controls, traceability and source-linked evidence — assembled as you go.
Each section is generated from data you already hold or captured through guided intake — and tied back to the evidence that supports it.
Criteria, boundary, period, GWP basis and materiality — the foundation a verifier tests against.
Every site considered, included or excluded, with a control-based reason for each.
The signed responsible-party statement an engagement is built around — enforced before issue.
Source, vintage, region, type and units for every factor, with vintage-mismatch flags.
Monthly data per source, plus the named owner and reviewer for each stream.
Per-site, per-source working with the arithmetic shown — independently recalculable.
Monthly tie-outs, recalculation, completeness and duplicate detection — run automatically.
Source documents linked to each data point, with SHA-256 hashing and chain of custody.
Append-only record of who entered, reviewed and approved every figure.
Evidence that each control actually operated over the period — not just that it exists.
Population counts ready for the verifier to select against — independence preserved.
Prioritised list of what to fix before fieldwork — generated from the package itself.
ISO 14064-3 requires that whoever checks your numbers is independent of whoever prepared them. ThemisIQ is the tool you prepare with — built to stop exactly where it should.
ThemisIQ assembles your package and never authors your assertion or issues an opinion. You choose your own accredited verifier and control their access. That separation isn't a limitation — it's the very thing ISO 14064-3 independence requires, built into how the product works.
Verification Readiness layers on top of your Climate-GHG inventory. Pay only when you need a package verified.
Climate-GHG — your Scope 1, 2 & 3 inventory engine.
Everything needed to hand a verifier a defensible package — verifier access included.
Turn the number you already have into a package a verifier can test efficiently — and shorten the engagement that follows.
