CBAM Has Shifted from Policy to Process
During the transitional phase, CBAM was often owned by sustainability or regulatory teams. Reporting was periodic, largely manual, and based on customs clearance data, with limited financial exposure.
Since 2026, that model no longer works.
CBAM now requires:
- Alignment between emissions data and customs declarations, including origin, net weight, and product classification
- Time Accurate emissions data at shipment level, provided by suppliers
- Monitoring of net weight volumes to manage the 50-tonne threshold
- Ongoing management of certificate calculations, purchases and surrender
- Financial forecasting tied to carbon pricing
These requirements cut across multiple functions, creating friction where ownership is unclear.
Where CBAM Breaks Down in Daily Operations
1. Customs teams carry the declaration risk
Customs teams are responsible for import customs clearance. However, they do not control the emissions data used for CBAM reporting.
This creates several operational risks:
- Unclear origin data
- Mismatches between declared net weights and supporting documentation
- Incorrect product classifications
Customs records form the base of the CBAM report. The European Commission compares customs declaration data with the data submitted in the CBAM Trader Portal. Discrepancies increase the likelihood of review, correction, or audit follow-up.
2. Compliance teams are waiting for data
Compliance teams are responsible for validating emissions data before submission of the CBAM report. However, they often depend on upstream information that arrives late or incomplete.
CBAM reporting data must align with customs declarations. If emissions values are incorrect or misaligned with customs declarations, importers may:
- Report incorrect tonnage, including falling below or exceeding the 50-tonne threshold
- Fail to link declarations to the correct CBAM account
- Underreport or overreport embedded emissions, resulting in additional costs
- Trigger additional scrutiny by the national competent authority
- Face administrative penalties for misreported emissions
Without a structured supplier onboarding and data validation process, uncertainty increases and operational friction follows.
3. Supplier engagement and Emissions Data Responsibility
Suppliers play a central role in CBAM compliance. They control the production processes that determine embedded emissions, which directly affect the importer’s financial exposure.
If supplier expectations are unclear:
- Verified emissions data may not be provided
- Default values must be applied
- CBAM costs increase
- Product pricing becomes less competitive
- Customer relationships may be affected by higher landed costs
Importers should engage suppliers early and set clear expectations regarding emissions data transparency. Emissions reporting requirements should be addressed during supplier onboarding and, where necessary, formalised contractually.
Without structured supplier engagement, CBAM compliance becomes reactive and cost exposure increases.
4. Finance teams are involved too late
CBAM introduces a variable cost linked directly to EU carbon pricing. However, finance teams are often engaged only once certificate purchases become necessary.
This can result in:
- Insufficient financial guarantees where required by the national competent authority
- Difficulty purchasing CBAM certificates when required
- Limited visibility into future CBAM
mexposure - Budget overruns driven by default emissions values
- Difficulty allocating CBAM costs to product or business units
Without early financial involvement, CBAM becomes a reactive expense rather than a managed cost component.
Why Siloed Ownership Increases CBAM Risk
CBAM does not fail because teams ignore it, but because each team sees only part of the obligation.
Customs focuses on clearance. Compliance focuses on data quality. Finance focuses on cost control. CBAM requires these functions to operate on the same data, at the same time.
When ownership is fragmented:
- Data is duplicated or inconsistent
- Deadlines are missed
- Compliance becomes expensive and unpredictable
Without clear accountability and shared data governance, operational risk increases quickly. Clear ownership and structured controls are essential.
What an Integrated CBAM Operating Model Looks Like
Companies that manage CBAM effectively treat it as a shared operational process.
Key characteristics include:
- A single source of truth for CBAM-relevant data
- Clear ownership of emissions data, customs submission, and financial forecasting
- Early supplier engagement tied to operational deadlines
- Integration of sustainability data with customs systems
This approach reduces risk while improving cost control and predictability.
How ALS Helps Bridge the Gap
At ALS Customs Services, we support businesses where CBAM has moved from theory into daily operations.
We help companies:
- Align CBAM data with customs declarations and classifications
- Coordinate emissions data flows across custom clearance processes
- Integrate CBAM requirements into existing customs procedures
- Support certificate management and ongoing compliance
By treating CBAM as an operational customs issue, not a standalone sustainability task, ALS helps businesses reduce friction and stay compliant.
With ALS, customs are simplified, and trade is amplified.
Key Takeaways
- CBAM compliance now affects daily import operations, not just reporting cycles.
- The biggest risks appear between customs, compliance, and finance teams.
- Customs teams often lack timely access to emissions data.
- Misaligned supplier data increases compliance risk and cost exposure
- Finance teams require earlier visibility into CBAM cost exposure, supported by structured supplier onboarding and data collection processes
- Integrated ownership and data alignment reduce risk and cost volatility.
Treating CBAM as a shared operational process is now essential.
