Accurate CBAM Reporting with Zero Hassle and Zero Delay

What is CBAM & Why it Matters?

Definition

The Carbon Border Adjustment Mechanism (CBAM) policy was introduced by the European Union (EU) in October 2023 and forms the foundation of mandatory CBAM compliance for carbon-intensive imports. It places the import duty on the greenhouse gas (GHG) emissions in the production of selected imports. The industries currently covered under this policy include aluminium, cement, steel, fertilisers, electricity, and hydrogen.

Purpose

The CBAM policy is aimed at the prevention of ‘carbon leakage’ (when companies move production to countries with weaker climate rules and thus lower cost of production). This is how it ensures fair competition between EU and non-EU producers.

Business Relevance

Companies outside the EU must comply with CBAM if they export covered products, making CBAM compliance services and reliable CBAM consulting critical for accurate emissions reporting and cost management. High-emission products will become costlier, thus making low-carbon producers more competitive.

How Does the CBAM Mechanism Work?

The process of CBAM involves the following aspects:

Import of Covered Goods

CBAM applies to imports of carbon-intensive goods such as cement, electricity, fertilisers, aluminium, steel, iron, and hydrogen. The imports from countries already in the EU ETS, such as Norway, Liechtenstein, Iceland, and Switzerland, are exempted.

Registration of Importers

The companies importing CBAM goods need to apply from January 1, 2025, to become Authorised CBAM Declarants. The restrictions will be imposed from January 1, 2026, allowing only registered declarants to import CBAM goods.

Reporting of Embedded Emissions

Importers need to submit quarterly CBAM reports using a structured CBAM reporting tool, detailing the quantity of imports, direct and indirect embedded emissions, and any carbon price already paid in the country of origin.

These reports are mandatory but do not involve financial obligations at this stage. The submitted reports are further processed for data verification if actual values are used. They are verified by a certified testing body.

Purchase of CBAM Certificates

Importers must buy CBAM certificates that correspond to the amount of embedded carbon dioxide equivalent (CO2e) emissions in their imports. The price of each certificate mirrors the average EU ETS allowance price. Any carbon tax paid abroad is deducted to avoid double-charging.

Annual CBAM Declaration and Reconciliation

By May 31st each year, authorised declarants must file an annual CBAM declaration showing imports and related emissions from the previous year. The declaration is compared against the number of certificates purchased. If too few certificates are acquired, financial sanctions could be imposed.

CBAM Reporting Requirements and Timeline

The CBAM is divided into two phases: the transitional phase and the definitive regime. While the first one deals with the reporting aspect, the second will be concerned with financial obligations. Here are the detailed insights into the two phases:

Transitional Phase (2023–2025): Key Obligations for EU Businesses

From October 2023 to the end of December 2025, the companies are obligated to report on their emissions. There are no financial obligations within the mentioned period. This transitional phase allows businesses to implement CBAM reporting software, test reporting workflows, collaborate with suppliers, and address data gaps before financial obligations begin. They can also prepare to become an Authorised CBAM Declarant if continuing imports into 2026.

Reporting obligations include:

• Quarterly report submission that covers direct emissions from imports
• Incorporate actual emissions data from producers, if available, or use equivalent or default methodologies
• Produce traceable data

The reports must be filed by the end of the month after the quarter.

Definitive Regime (from 2026): The Post-2026 Landscape

This phase will involve stricter CBAM reporting, where the companies will be financially obligated and increasingly dependent on reliable CBAM reporting services for annual declarations and certificate management. The importing companies will submit annual reports and purchase CBAM certificates to cover embedded emissions.

Here is what specifically the companies must do:

1. Annually submit the CBAM declaration for all the imports from the past year
2. Buy and hand over CBAM certificates equal to the emissions in those imports
3. Choose certificates based on the weekly EU ETS average
4. Deduct the already paid carbon costs
5. Get the emissions data verified by an independent body

Companies can choose between two methodologies to calculate emissions:

1. The calculation-based approach involves the calculation of emissions indirectly. It can be used:
   • Activity data with emission factors: It can be used for tracking the amount of consumed fuel, electricity, or raw material and multiplying the value by standard factors. The result will be how much carbon dioxide each unit generates.
   • Mass balance method: It compares the carbon content of all materials entering and leaving the production process to estimate how much carbon is released as emissions.
2. The measurement-based method is more direct. It measures the actual concentration of greenhouse gases and the volume of the flue gases released at the manufacturing site. This provides emissions data based on real-time monitoring rather than estimates.

Handle the Reporting, Certificates, and Documents in the Official Registry

Before 2026, the companies must register as an authorised CBAM declarant with their national authority. They will need to plan their budget for buying certificates, collecting verified emissions data for each product, and ensuring suppliers can provide accurate information. Any delays, missing data, or mistakes could lead to higher costs or penalties.

Recent Updates

The EU proposed the Omnibus or Simplification Package in early 2025. These are a set of updates designed to streamline CBAM processes and support its proper implementation from 2026.

• 50 tonne exemption rule: Importers bringing in less than 50 tonnes of a CBAM product annually are exempt from reporting and certificates, but must track volumes.
• Simplified authorisation and digital portal: Becoming an authorised declarant is easier. Third parties can file for the companies, and all processes will run through a single EU CBAM portal.
• New deadlines for certificates and reports: Tracking begins in 2026, but the first certificates are due in 2027. The new deadlines for reports are 31 August and for certificates are 31 October.
• Narrowed emissions scope: CBAM now covers only direct emissions, including electricity use. The emissions do not cover steam, heat, and cooling to ease reporting.

Implications of CBAM

The implications of CBAM for importers are stated as follows:

1. Business-Level Impacts

Financial

Importers will face increased costs due to the requirement of CBAM certificate purchases. Thus, there will be a rise in product prices across sectors like aluminium, steel, and cement. Further, developing countries will also face high costs to comply with CBAM when exporting to the EU. The economic impact on these countries could exceed the revenues generated by the CBAM, potentially causing financial strain.

Operational

Companies must adjust supply chains by working with suppliers who can provide verified emissions data, increasing contractual and compliance complexity. The businesses operating in developing countries may lack time, resources, and systems to align with the EU's carbon pricing, thus creating operational difficulties.

Strategic

Importer firms will be pushed to accelerate low-carbon transitions, invest in greener technologies, and reorient sourcing toward suppliers with lower embedded emissions. Exporters may need to modernise production and adopt low-carbon technologies to remain competitive in the EU market. Other countries will also need to negotiate with the EU to secure fairer implementation and protect trade interests.

2. Risks of Non-Compliance

Penalties

Failure to submit accurate reports or surrender certificates on time can result in financial fines.

Market Access

Persistent non-compliance could lead to restrictions or even loss of access to the EU market.

CBAM in the Context of Climate and ESG Regulations

CBAM is part of a broader climate and sustainability regulatory landscape. It does not operate in isolation and links directly with the EU Emissions Trading System (EU ETS). It ensures that imported products face similar carbon costs as domestic producers.

CBAM supports companies in meeting ESG reporting rules, like CSRD and GHG protocol. It eases the companies to include carbon compliance in their existing sustainability efforts. Moreover, it also prepares them for future global carbon pricing rules since similar systems may appear in other countries.

Imports like steel and aluminium will need CBAM certificates, and more products will be covered as free ETS allowances are phased out from 2026 to 2034. CBAM and ESG reporting will be easier due to the use of consistent methods such as GHG protocol standards, lifecycle assessments, and verified supplier data.
