Your coordination checklist

Choose a status for each item, then run the check.

Why start here?

The Commission describes O3CI as a route for non-EU operators to share installation and emissions information with declarants. It specifically notes that declarants must communicate their EORI to the supplier outside the registry. Check that handoff before resending files.

A practical handoff

Choose one product family and one installation to troubleshoot first.
Record the problem, owner and next step for each unanswered item.
Keep sensitive supporting documents in an agreed secure channel, not a public group.

For teams already considering the O3CI sharing route. This is not an assessment of whether your goods fall within CBAM, whether an exemption applies, or whether O3CI registration is mandatory for your business.

CBAM data shared but not verified: what to request

Treat this as a coordination question, not a failed-compliance verdict. The next step depends on where the handoff stopped.

Record not visible
Confirm the installation, reporting period and intended recipient together. A resent spreadsheet does not show that the right registry record is visible.
Record visible, verification unclear
If actual emissions are planned, identify the verification owner and report status. Sharing a record does not replace an accredited independent verifier.
Report not yet available
Record the planned next step and expected availability. The Commission's timeline puts first reports in January 2027; do not mark an absent report in September 2026 as an automatic failure.

Common questions

Does this tool submit anything to the EU?

No. It only prepares a local coordination checklist. Use the official registry for official actions.

Is shared data automatically verified?

No. Registry sharing is not independent verification. If using actual emissions, consult the Commission's rules for accredited independent verifiers; this checker cannot verify emissions.

Does a missing verification report in September 2026 prove a failure?

No. The Commission's published timeline places the first verification reports in January 2027. Ask for the status and expected availability, rather than assuming a report must already exist.

What should I ask my supplier to send next?

Start with one installation and reporting period. Ask for the sharing recipient, retrieval status and, where actual emissions are planned, the verification owner and report status. Use the free request template and an agreed secure channel.

Can I buy the €299 evidence pack here?

Not yet. €299 is an indicative pilot price, not an active checkout. The separate EcoBack storage membership is not this evidence pack.

Before paying for help

The checklist and supplier request template are free. A proposed €299 evidence-pack pilot would organise one product family's bilingual document index and tailored follow-up list. It is not verification or a declaration service. Scope, tax treatment and delivery terms must be agreed before any charge; checkout is not connected.

The EcoBack storage membership is a separate product and does not buy this evidence service.
