Get real emissions data from your supplier, not defaults

The single biggest CBAM cost driver of 2026 is not the carbon price — it is filling in default values because the supplier never sent actual data. Defaults under Regulation (EU) 2023/956 are deliberately conservative: using them can cost multiples of the real figure. This page gives you the two instruments to change that: a request e-mail in your supplier's language, and the exact field list to put in it. Copy, send, collect.

Free, no account, nothing to install. The e-mails name the regulation and the consequence; suppliers respond to cost and to regulation, not to polite requests.

What to ask for — the field list

FieldWhat it means, in supplier terms
CN codeThe 8-digit Combined Nomenclature code of the product you supply
Production siteName and full address of the installation where the good is produced
Process routeThe production process used (e.g. blast furnace / electric arc, prebake / Soederberg)
Direct emissionstCO2e per tonne of product, scope 1 at the installation
PrecursorsEach input material with embedded emissions and its supplier data, if any
Electricity mixTechnology-specific or country-specific emission factor used, and which
PeriodWhich period the data covers (quarter, year)
EvidenceAny verification, certificate or measurement basis available
Source: Regulation (EU) 2023/956 implementing provisions on embedded emissions and default values; the pragmatic framing is ours. Checked: 20 September 2026.

Subject: Emission data needed for our EU import (CBAM)

Dear [supplier],

Since 1 January 2026 our imports into the EU fall under the Carbon Border
Adjustment Mechanism (Regulation (EU) 2023/956). Without actual emission
data from you, EU law forces us to use punitive default values, which makes
your products significantly more expensive for us than they need to be.

Please provide, per production site and per CN code, for the goods you
supply us:
  1. direct emissions (tCO2e per tonne of product);
  2. relevant precursor materials and their embedded emissions, if any;
  3. the production process route used;
  4. the installation name and address.

An Excel sheet with the exact fields is in the table below; a filled
ISO-certified verification is welcome but not required for our first
declaration.

Without your data we must either use the defaults or reconsider volumes.

Kind regards,
[name], [company]

Subject: 我们欧盟进口所需的排放数据(CBAM 碳边境调节机制)

尊敬的 [供应商]:

自2026年1月1日起,我们进口到欧盟的货物受欧盟碳边境调节机制
(第2023/956号条例)约束。如果没有贵方提供的实际排放数据,欧盟法律
将迫使我们使用惩罚性默认值,这会使贵方产品对我们的成本大幅上升。

请按生产场地和CN编码,就供应我们的产品提供:
  1. 直接排放(每吨产品的二氧化碳当量吨数);
  2. 相关前驱体材料及其内含排放(如有);
  3. 所使用的生产工艺路线;
  4. 生产设施的名称与地址。

下方表格列明了确切字段。欢迎提供经核证的证明,但我们首次申报并非
必须。若无法提供数据,我们只能使用默认值或重新考虑采购量。

此致

Subject: Данные о выбросах для нашего импорта в ЕС (CBAM)

Уважаемый [поставщик],

с 1 января 2026 года наш импорт в ЕС подпадает под Механизм пограничного
углеродного регулирования (Регламент (ЕС) 2023/956). Без фактических данных
о выбросах от вас законодательство ЕС вынуждает нас применять штрафные
значения по умолчанию, что существенно удорожает вашу продукцию для нас.

Просим предоставить по каждому производственному объекту и коду CN для
поставляемой нам продукции:
  1. прямые выбросы (тCO2e на тонну продукции);
  2. исходные материалы и их встроенные выбросы (при наличии);
  3. используемый технологический процесс;
  4. наименование и адрес установки.

Точная структура полей — в таблице ниже. Подтверждение с сертификацией
приветствуется, но для первой декларации не обязательно.

Без данных нам придётся использовать значения по умолчанию или пересмотреть
объёмы закупок.

С уважением,
[имя], [компания]

When the data arrives

Turn it into a cost figure

Put the actual values next to the defaults in the CBAM calculator and guide and see the difference per tonne and per shipment. If the gap is large, that number belongs in your next price negotiation — and in your supplier's next sales pitch, which is exactly the argument in the e-mail above. For anything beyond the arithmetic, ask us.
