Carbon Border Adjustment Mechanism (CBAM / SKDM): What Companies Need to Know

The European Union’s climate policies are reshaping international trade. One of the most strategic tools in this transformation is the Carbon Border Adjustment Mechanism (CBAM)—also known as SKDM in Turkish.

CBAM aims to reduce the risk of “carbon leakage” (i.e., emissions shifting to countries with less ambitious climate policies) and to support the EU’s decarbonization goals. For companies exporting to the EU, CBAM/SKDM turns carbon data and transparent reporting into a commercial requirement—not just a compliance topic.

What Is CBAM/SKDM?

The Carbon Border Adjustment Mechanism is an EU regulatory framework that requires importers to account for the embedded greenhouse gas emissions in certain goods when they enter the EU market.

In practice, CBAM requires emissions-related reporting during an initial transition period and, later, introduces the need to purchase CBAM certificates to cover the carbon costs of those embedded emissions.

Why Does CBAM/SKDM Matter for Businesses?

CBAM/SKDM affects companies at multiple levels:

Export competitiveness: Providing accurate emission data improves credibility and helps avoid delays or unfavorable commercial treatment.
New reporting responsibilities: Carbon reporting becomes part of your supply chain documentation.
Risk management: Incorrect, incomplete, or late reporting may lead to financial and operational risk.

At the same time, companies that prepare well can turn this compliance effort into an advantage—by accelerating decarbonization investments, improving operational efficiency, and strengthening market trust.

CBAM Transition Period: Where Are We Now?

CBAM started with a transition phase on 1 October 2023, moving through two key stages:

Transition phase: Importers focus on collecting and reporting embedded emissions data (without paying for certificates yet).
Main implementation phase: The purchase of CBAM certificates becomes part of the system.

The exact timeline is evolving, but the message is clear: data collection and reporting capabilities must be built early.

Which Sectors and Products Are Covered?

CBAM applies to goods in sectors selected based on carbon intensity and risk of carbon leakage. These currently include:

Cement
Electricity
Fertilizers
Iron and steel
Aluminum
Hydrogen

These categories reflect emissions-intensive production pathways and the need for better transparency across cross-border supply chains.

What Does “Embedded Emissions” Mean?

“Embedded emissions” refers to the greenhouse gas emissions emitted during the production of imported goods, embedded in their lifecycle until they enter the EU market.

CBAM focuses on the emissions associated with the production of goods and requires that reporting be aligned with accepted methodologies and verifiable data.

How Does CBAM Reporting Work?

CBAM reporting is built around robust data management:

Activity data collection: Collect site- and product-level information needed to estimate emissions.
Emission calculation methodology: Use accepted factors and verified processes to convert activity data into emissions totals.
Documentation and traceability: Ensure reporting is audit-ready and can be traced back to evidence sources.
Quarterly reporting (during transition): Submit reports on the required schedule.

In short: CBAM reporting is as much a data governance task as it is a carbon calculation task.

Key Responsibilities: Who Needs to Do What?

Responsibilities typically fall on:

EU-established importers (the entities performing CBAM reporting)
Indirect customs representatives (where applicable)
Non-EU suppliers/exporters (who must provide accurate emissions and supporting documentation)

If you are an exporter to the EU, you should expect requests from importers to support the embedded emissions reporting with credible, traceable information.

What Should You Do to Stay Compliant?

Start with the fundamentals:

Map your supply chain data for covered products and production sites.
Build a documentation package that can be shared reliably with importers.
Align on methodology (how emissions are calculated and how data quality is ensured).
Set an improvement roadmap to reduce emissions and lower long-term compliance risk.

In many cases, a phased approach works best: begin with data collection, validate calculations, then move into improvement initiatives that reduce embedded emissions.

Why 3pmetrics?

CBAM/SKDM preparation requires more than calculations—it requires a reporting-ready approach across teams and partners. With 3pmetrics, you get technical guidance, data collection support, and methodologies aligned with recognized standards so you can prepare early and reduce risk.

Conclusion

CBAM/SKDM is becoming a core part of sustainable international trade. Companies that invest in data quality, traceability, and early compliance not only meet regulatory expectations—they also strengthen competitiveness in the EU market and accelerate their decarbonization journey.
