As the Carbon Border Adjustment Mechanism (CBAM) moves from transitional reporting to full compliance obligations, December marks the final turning point for organisations preparing to operationalise emissions reporting and supplier engagement.
2025 exposed the complexities of product-level emissions, data exchange with suppliers, and the challenges of validating embedded carbon across diverse manufacturing environments. The transition to compliance in 2026 will be unforgiving for organisations that have not built the right data and process foundations.
What 2025 Made Clear
Throughout the year, three consistent obstacles emerged:
- Supplier-level emissions data gaps, especially for smaller manufacturers or suppliers outside highly regulated markets.
- Uncertainty around data quality, with companies struggling to validate supplier-reported emissions.
- Operational readiness, particularly for organisations with decentralised procurement or category-driven structures.
As December approaches, the task is no longer exploratory. It’s executional.
The December Priority: Build Your CBAM Compliance Blueprint as an Importer
As the transition to full CBAM compliance approaches, importers must move decisively from preparation to execution. December is the final window to build a robust compliance blueprint focused on the specific demands facing importers. To ensure operational readiness, organizations should address four critical foundations:
1. Confirm In-Scope Imported Products and Suppliers
For importers, misclassification of products or suppliers significantly increases compliance risk. This period is the last opportunity to rigorously validate:
- Which imported goods are subject to CBAM regulations.
- Which international suppliers are contributing embedded emissions to your imports.
- Which product categories or supply chains require additional tracing or supplier engagement to capture accurate data.
2. Set Supplier Data Expectations for Imported Goods
Importers must clearly articulate and communicate data requirements to all suppliers—particularly those outside the EU. Starting in 2026, these expectations should include:
- Product-level embedded emissions clearly allocated to imported batches.
- Documentation of calculation methodologies that comply with EU standards.
- Third-party verification status to ensure reliability.
- Granularity of data, with facility- or production line-specific attributes where necessary.
Early and transparent engagement will reduce delays and errors in data delivery when full compliance becomes mandatory.
3. Build Internal Import Compliance Workflows
Effective CBAM implementation depends on a structured internal process tailored to the realities of cross-border sourcing. Importers must define:
- How procurement, sustainability, and finance teams collaborate to collect, validate, and report emissions data for imported products.
- Who owns escalation paths for missing, incomplete, or inconsistent data, and how issues are resolved.
- How quarterly and annual reporting for imported goods aligns with CBAM requirements for accuracy and timeliness.
4. Validate Your Approach to Import Emissions Data
Every importer should verify that their data management processes can withstand regulatory scrutiny. This entails:
- Consolidating supplier data from multiple origins into a traceable, auditable repository.
- Establishing robust verification procedures for all emissions data associated with imports.
- Identifying and supporting suppliers that need to improve their emissions reporting practices before 2026 begins.
Conclusion: From Preparation to Obligation
In 2026, CBAM shifts from a reporting exercise to a binding financial and regulatory obligation. Importers will be required to demonstrate accurate embedded carbon calculations, ensure validation, and maintain a consistent, repeatable internal compliance cycle.
Beyond regulatory requirements, the financial impact of CBAM will be immediate and substantial. The cost of purchasing CBAM certificates, tied to verified embedded emissions, will directly affect importers’ bottom lines. Failing to secure accurate data or ensure timely compliance exposes organizations to significant penalties and unanticipated expenses. To mitigate these risks, importers must prioritize robust internal controls, invest in data management solutions, and collaborate closely with suppliers to minimize both emissions and cost exposure. Forecasting, budgeting, and proactive procurement strategies will be essential to maintaining cost competitiveness in an evolving regulatory environment.
Organizations that have treated 2025 as a preparatory year and used this time to build a strong compliance foundation will be best positioned to manage both their regulatory and financial obligations. Success in the new CBAM landscape depends on disciplined control over emissions data and a clear strategy to address the cost of compliance. The time for planning is over; the time for operational and financial readiness is now.
