# Is the Commission's CBAM emissions report template mandatory for suppliers?

Canonical: https://senseible.earth/answers/cbam-operator-emissions-report-template-mandatory

Yes. Where embedded emissions are based on actual data, the operator must prepare an annual operator's emissions report and a summary using the Commission's template. It is in English, so buyers in any member state find the same data in the same fields.

## What the template holds

- Emissions by production process and by 8-digit CN code.
- Free allocation adjustment data.
- A summary report generated automatically from the Excel version.

## Electricity exporters

Where electricity emissions are based on actual data, a declarant-specific addendum is also needed.

## When to send it

After the calendar year closes and verification is complete. Until the next year's report is ready, the latest verified one is used.

## What Senseible does here

Senseible reads an exporter's fuel and electricity invoices into dated, fingerprinted records that a monitoring plan and a verifier can trace back to source. Senseible does not verify emissions, register operators in the CBAM Registry or file CBAM declarations.
