CBAM Data Readiness: Emissions Records Needed by EU Importers
The Carbon Border Adjustment Mechanism (CBAM) is the EU mechanism for emissions reporting and later certificate obligations for selected imported high-emission goods. The current scope should be determined by the legal annex and CN code, mainly covering specified goods in cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen.
Exporters should not simplify CBAM into a single cost mechanism for all exported products, and customer-facing articles should not publish unconfirmed cost ratios, carbon-price forecasts, or expansion timelines. The practical task is to help EU importers obtain verifiable product and emissions data.
First Confirm Whether the Product Is in Scope
| Check item | What to confirm | Data source |
|---|---|---|
| Commodity code | Whether the CN code is included in the CBAM list | Customs records, product specifications, EU importer confirmation |
| Product category | Whether the product falls under specified cement, iron and steel, aluminium, fertiliser, electricity, or hydrogen goods | Technical file and sales contract |
| Production installation | Which facility, production line, and production route made the product | Factory file and production records |
| Responsibility split | Which data is provided by EU importer, customs representative, and exporter | Customer agreement and supply-chain communication records |
Data Exporters Should Prepare
- Product name, model, CN code, specification, and shipment batch.
- Production facility, production route, output, and energy-use records.
- Direct emissions and indirect emissions where required.
- Input materials, semi-finished goods source, and supplier records.
- Calculation method, data source, reporting period, and boundary explanation.
- Any third-party verification or internal-review records should be archived separately.
Do Not Treat Default Values as a Long-Term Plan
During transition or where data is incomplete, importers may use default values or conservative estimates, but this may not reflect the producer's actual production performance. Exporters that want to reduce data uncertainty for customers should build facility-level and product-level emissions tables early and align the data language with EU customers.
How This Differs from Product Carbon Footprint
CBAM data serves a specific regulatory declaration purpose, while product carbon footprint or LCA may be used for customer disclosure, EPD, green claims, or supply-chain management. They can share some base data, but their calculation boundary, method, and use case differ, so they should not be substituted for one another without review.
Greenark (Shenzhen) Certification Co., Ltd.'s Recommendation
Greenark (Shenzhen) Certification Co., Ltd. recommends that exporters first screen by CN code, then build facility and product emissions ledgers. The key to CBAM readiness is traceable data, consistent methodology, and the ability to answer EU importer reporting needs. Final scope and reporting requirements should follow EU CBAM official rules, later implementation documents, and importer requirements.
