Collecting emissions data from your suppliers is essential for tracking and managing your purchased articles accurately within kolum. By gathering supplier-provided emissions data, you ensure your records reflect the upstream footprint of your goods, enabling transparent reporting and clear supply chain visibility. Suppliers can provide emissions data for purchased CBAM goods either by submitting it directly in kolum or by sending the data in bulk using the Excel or CSV upload template. Once the supplier provides the data, it is linked automatically to your articles and imports, ensuring your emissions data is organized and ready for validation when needed. When you add a new supplier in kolum, you can link them to specific purchased CBAM goods by assigning the CN code when you create the import and connect it to that supplier. Those items then appear on the supplier's side, allowing them to submit emissions data only for the goods they provide, at the CN-code level. If multiple articles share the same CN code, the supplier only needs to enter the data once. Using kolum to collect emissions data from suppliers keeps your workflow efficient while ensuring accountability and reducing manual data entry.

Options for Collecting Emissions Data

Supplier Enters Emissions Data Directly via kolum: Invite your supplier to kolum, link them to the relevant purchased CBAM goods, and allow them to enter direct and indirect emissions data directly within the platform. This is best when your suppliers have the emissions data readily available and are active on kolum.

Reporting Timeframe on the Purchased CBAM Goods page

Purchased CBAM Goods now lives on its own CBAM tab on the supplier's detail page, rather than a panel on the main profile. When you open a supplier's Purchased CBAM Goods (Supply Chain → Suppliers → [Supplier] → CBAM tab → Purchased CBAM Goods), a Reporting Timeframe selector scopes the rows shown. A CBAM good appears for a timeframe when at least one CBAM-relevant import for that Supplier × CN Code × Country of Origin falls inside it.

On load, the selector defaults to the latest quarter that has at least one import for that supplier, where an import's quarter is derived from its import date. If the newest quarter has no imports for the supplier yet, the selector falls back to the most recent earlier quarter that does, so each supplier's table opens on a quarter that actually has data for that supplier, which can differ from supplier to supplier. Only transitional and forecasting timeframes are considered for this default; definitive-year timeframes are never auto-selected, and when the supplier has no imports at all the latest forecasting timeframe is selected. A quarter you choose manually is kept for the rest of your session, and you can switch freely to any timeframe.

The Purchased CBAM Goods table

The Purchased CBAM Goods table shows the embedded emissions and CBAM cost for each purchased good, scoped to the selected Reporting Timeframe. Its columns are:

SEE Direct and SEE Indirect: the direct and indirect specific embedded emissions (renamed from the previous emission columns). When the emission data type is Actual, each value also shows a delta indicator: the percentage difference versus the CBAM default for that figure, a green down arrow when the value is below the default (lower emissions than default), a red up arrow when it is above. Hovering the percentage shows a tooltip that spells out the comparison and the default value with units, e.g. -11.90% vs CBAM default (2.10 tCO₂e/t). Default rows show no delta.
SEFA: the Specific Embedded Free Allocation.
CBAM-Liable Emissions: the emissions that remain liable after free allocation.
Total CBAM Cost: a single cost column that consolidates the previously separate cost columns; a Default-based CBAM cost is shown where actual data is not available.

Columns are ordered to match the current design. For Reporting Timeframes from 2026 onward, a Production Route column (shown as letter, name) replaces Production Method; earlier timeframes keep Production Method behind a view with a legacy/deprecated badge.

Editing emission data for a purchased good

When you edit a purchased good's emission data, the edit page shows which Reporting Timeframe you are editing and includes a Specific Embedded Free Allocation (SEFA) input, mirroring the supplier view. Saving your edits automatically marks that data as Actual for the selected timeframe.

Requesting an Update from a Supplier

Use the Request Update button on the Suppliers page to ask a supplier to provide new emission data for the reporting timeframes that currently require it. When you request an update, the supplier is sent a dedicated email whose call-to-action deep-links them straight to the buyer submission page for the relevant entry, so they land directly on the form they need to complete. For 2026+ timeframes, the request-update email and the notification you receive when a supplier submits data both show the Production Route as letter, name, matching the table.

What's new

A supplier's Purchased CBAM Goods now sit on a dedicated CBAM tab of the supplier page, and the emails around supplier data requests show the Production Route the same way the table does: the Request Update email and the notification you receive when a supplier submits data both name the route as letter and name for 2026 and later timeframes.
