CBAM Supplier Data Request Generator
Getting actual emissions data from a non-EU supplier is the hardest part of CBAM — and the difference between a fair certificate bill and the punitive default mark-up. Fill in a few fields and get a professional, sector-correct request, in your supplier’s language, ready to send.
Request for CBAM embedded-emissions data — Steel — Blast Furnace / Basic Oxygen Furnace (BF-BOF) Dear Sir or Madam, Our company imports your goods into the European Union. From 2026, EU importers are legally required under the Carbon Border Adjustment Mechanism (CBAM, Regulation (EU) 2023/956) to report the embedded greenhouse-gas emissions of these goods and to surrender CBAM certificates covering them. To do this accurately, we need the actual emissions data from your installation. Where verified actual data is not available, we must use the EU default emission values, which carry a punitive mark-up — 10% in 2026, 20% in 2027, and 30% from 2028. These defaults are deliberately conservative and usually overstate real emissions, which raises the carbon cost of your goods and makes them less competitive than those of suppliers who provide accurate data. Sharing your actual data is therefore in both of our interests. For the product below, please provide the following installation and emissions data for the reporting period 2026: Product: Steel — Blast Furnace / Basic Oxygen Furnace (BF-BOF) Production route: Steel — Blast Furnace / Basic Oxygen Furnace (BF-BOF) 1. The name, full address and country of the installation where the goods are produced (with UN/LOCODE or geographic coordinates if available). 2. The legal name of the installation operator and a contact person for emissions data. 3. The production route and the main processes used to manufacture the product. 4. The direct specific embedded emissions of the product (tonnes CO₂e per tonne of product), determined in line with the CBAM methodology in Annex IV of Regulation (EU) 2023/956. 5. For each relevant precursor material (for example pig iron, direct reduced iron, crude steel or ammonia): its embedded emissions and the share it contributes to the final product. 6. The monitoring period the data covers, and whether the figures are measured or calculated. 7. Whether the emissions data has been, or can be, verified by an accredited independent verifier. 8. Whether a carbon price (a tax or emissions-trading cost) has already been paid in the country of production for these emissions, and if so the amount per tonne of CO₂ and any rebates. A carbon price paid at origin can reduce the CBAM obligation. The European Commission provides an official CBAM communication template that installations can use to report this data in a standardised form. We are glad to send it to you on request; alternatively you may return the information in your own format. Please send this information by the date indicated below, so that we can complete our CBAM reporting on time. If anything is unclear, or you would like us to provide the official reporting template or a worked example, please contact us — we are happy to help you through the process. Thank you for your cooperation. Kind regards, — This message supports emissions reporting under Regulation (EU) 2023/956 (CBAM). It is a request for data, not legal advice.

Why Supplier Emissions Data Is the Real CBAM Battleground
Under the Carbon Border Adjustment Mechanism, every tonne of covered goods you import carries an embedded-emissions figure that determines how many CBAM certificates you must buy. You have two ways to set that figure: the EU default values from Implementing Regulation (EU) 2025/2621, or the actual verified emissions from the installation that made your goods.
The defaults are not neutral. They carry a deliberate mark-up — 10% in 2026, 20% in 2027 and 30% from 2028 — and are set conservatively high so that importers have a strong incentive to obtain real data. For a carbon-intensive product from a high-emitting route, the gap between the default and the supplier’s actual figure can move your certificate bill by a wide margin. The single most valuable thing you can do to control CBAM cost is get accurate data out of your supplier — which is exactly what this tool is built for.
What the Generated Request Contains
The request is not a generic letter. It selects the correct data points for your production route and explains, in language a non-EU producer will understand, why it is in their interest to respond — because default values make their goods look dirtier and pricier than a competitor who reports real numbers. Every request includes:
- Installation identification — name, address, country, and operator contact.
- The direct specific embedded emissions per tonne, per the Annex IV methodology of Regulation (EU) 2023/956.
- Sector-specific items — precursors for steel, PFCs for primary aluminium, the clinker ratio for cement, feedstock for fertilizers and hydrogen, the grid factor for electricity, and indirect emissions wherever the sector requires them.
- The monitoring period, and whether figures are measured, calculated or verified.
- Any carbon price already paid at origin — which can be deducted from your CBAM obligation.
- A reference to the official EU communication template, and a clear response deadline.
Send It in Their Language
A request written in the supplier’s own language gets answered faster and more accurately. The generator produces the letter in English, Chinese, Turkish, Russian, Spanish and Portuguese, and picks the right one automatically from the country of production. You can override the choice at any time. Arabic, Hindi, Vietnamese and Korean are being added.
Frequently Asked Questions
Why do I need emissions data from my supplier for CBAM?
From 2026, EU importers must report the embedded emissions of CBAM goods and surrender certificates covering them. You can either use the EU default values — which carry a punitive mark-up of 10% in 2026, 20% in 2027 and 30% from 2028 — or the actual verified emissions from your supplier’s installation. Actual data almost always results in a lower certificate obligation, so collecting it from your supplier directly reduces your CBAM cost.
What emissions data should I ask my CBAM supplier for?
The core data points are: the installation name and location; the operator and a contact; the production route; the direct specific embedded emissions per tonne of product (per Annex IV of Regulation (EU) 2023/956); indirect emissions from electricity where the sector requires it; sector-specific items such as precursors, scrap share, PFC emissions, clinker ratio or feedstock; the monitoring period; whether the data is verified; and any carbon price already paid at origin. This tool selects the correct data points automatically for each of the six CBAM sectors.
Can I send the CBAM data request in my supplier’s language?
Yes. The generator produces the request in English, Chinese, Turkish, Russian, Spanish and Portuguese, and auto-selects the language from the country of production. A non-EU supplier is far more likely to respond — accurately and on time — to a clear request in their own language. Arabic, Hindi, Vietnamese and Korean are being added.
Is there an official CBAM template for suppliers to report emissions?
Yes. The European Commission publishes an official CBAM communication template that non-EU installations can use to report embedded emissions to their EU customers in a standardised form. The request generated here asks the supplier to complete that template or to return the same information in their own format.
This tool generates business correspondence to support emissions reporting under Regulation (EU) 2023/956 (CBAM). It produces a request for data and is not legal advice. The letter is assembled entirely in your browser; no data is transmitted.
