The European Union’s Carbon Border Adjustment Mechanism entered its transitional phase on 1 October 2023. The first quarterly report, covering imports during the final quarter of 2023, was due by 31 January 2024.
For the moment, importers are required to report rather than purchase CBAM certificates. That may make the transition appear administrative. It is more consequential than that. The system is beginning to connect customs declarations with information about emissions generated at production sites outside the European Union.
The initial scope covers selected goods in cement, iron and steel, aluminium, fertilisers, electricity and hydrogen, including specified precursors and downstream products listed by customs code. Exporters that supply these markets now need to understand not only what they produce, but how their production emissions will be calculated and communicated to European importers.
Carbon data is becoming commercial data
Many industrial facilities report energy consumption or company-level emissions for sustainability purposes. CBAM requires a more operational form of information. The importer needs data connected to the goods entering the European Union, the installation where they were produced and the methodology required under the regulation.
That creates a chain of responsibility. The European importer is responsible for the report, but much of the underlying information sits with the producer outside Europe. A weak data process at the plant can therefore become a customs and commercial problem for the buyer.
Exporters should establish who owns the data, who calculates it, who approves it and how it is transferred. Commercial agreements may need to address information quality, confidentiality, correction of errors and the consequences of late reporting. For industrial exporters serving Europe, carbon performance is becoming part of product competitiveness rather than a separate corporate report.
The practical work begins with product and process mapping
The first task is to confirm whether each product falls within the relevant customs codes. Similar goods may be treated differently depending on composition and classification. Producers should coordinate technical, customs and commercial teams rather than leaving the issue to one department.
The next task is to map the production process. This includes the installation boundary, direct emissions, relevant precursors and, where applicable, electricity consumed during production. The CBAM regulation defines embedded emissions and sets out methods for actual and default values, and the implementing rules provide the reporting framework for the transitional period.
The objective is not merely to generate a number before the deadline. The objective is to build a repeatable system that can withstand questions from importers, authorities and future verifiers.
Electricity strategy will influence export competitiveness
For several industrial products, electricity is a major part of cost and emissions. Two plants using similar production technology can have very different embedded emissions if their power sources differ.
This creates a direct link between industrial market access and energy infrastructure. Producers may need to examine renewable power contracts, captive generation, grid emission factors, efficiency improvements and process electrification. These decisions require capital and often depend on the availability of reliable power infrastructure in the host country.
A last-minute purchase of environmental certificates will not necessarily address the underlying calculation rules or the commercial expectation for credible production data. Industrial developers should therefore consider carbon intensity when selecting sites, utilities and technologies for new plants.
The transitional period should be used as a systems test
The current phase runs from 1 October 2023 to 31 December 2025, during which the importer’s obligations are limited to reporting under the CBAM regulation. The period is intended to collect information and prepare companies and authorities for the definitive system.
Exporters should use this time to identify gaps. Can the plant produce installation-level data? Are precursor emissions available? Are meters and records adequate? Can the information be traced to the goods supplied? Are responsibilities clear when production is outsourced or when several sites contribute to one product?
Default values may offer a temporary route where actual information is unavailable, but relying on defaults can leave a producer with less control over how its goods are assessed. A plant that can demonstrate reliable actual data will be in a stronger position to explain its performance to customers.
CBAM will influence new investment decisions
The mechanism is often discussed as a compliance issue for existing exporters. Its larger effect may be on future industrial projects.
A developer planning a steel, aluminium, cement, fertiliser or hydrogen project for the European market should now test the business case against carbon-related costs and reporting requirements. That includes the planned energy source, process technology, emissions monitoring, expected EU customer base and potential domestic carbon pricing.
The decision also affects consortium design. Industrial technology providers, power developers, digital monitoring companies, verification specialists and commercial advisers may all become part of the project development team earlier than before.
What companies should do before the first report
European importers should confirm the goods in scope, identify the relevant declarants and establish communication with suppliers. Non-European producers should provide structured information rather than waiting for individual customer requests.
Management should also treat the first report as a governance issue. Errors are more likely when customs, production, energy and sustainability teams work separately. One accountable process should connect product classification, emissions calculation, document control and customer communication.
CBAM is still developing, and the transitional period is designed to expose practical difficulties. Companies should expect guidance and methods to evolve. The direction, however, is already clear. Emissions information is moving closer to the transaction itself. For industrial exporters serving Europe, carbon performance is becoming part of product competitiveness rather than a separate corporate report.
