CBAM Explained: How the EU Carbon Border Adjustment Mechanism Impacts Regional Trade

The European Union's Carbon Border Adjustment Mechanism (CBAM) represents one of the most significant changes to international trade policy in decades. For regional exporters and logistics providers, understanding CBAM is essential for maintaining market access and competitiveness.

What is CBAM?

CBAM is the EU's mechanism to prevent carbon leakage—the phenomenon where companies relocate production to countries with less stringent climate policies. It requires importers of certain goods into the EU to purchase certificates corresponding to the carbon price that would have been paid if the goods had been produced under the EU's carbon pricing rules.

The mechanism applies initially to cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen—sectors with high carbon intensity and significant trade exposure.

Implementation Timeline

The transitional phase began in October 2023, requiring importers to report embedded emissions without financial obligations. From January 2026, full implementation begins, requiring purchase of CBAM certificates. The system will be fully phased in by 2034.

Calculation of Carbon Costs

CBAM certificates are priced based on the weekly average auction price of EU Emissions Trading System (ETS) allowances. Importers can deduct any carbon price already paid in the country of origin, preventing double taxation.

Embedded emissions include both direct emissions from production processes and indirect emissions from electricity consumption. Complex supply chains require tracking emissions across multiple production stages.

Impact on Regional Exporters

Regional manufacturers exporting to the EU face significant compliance requirements. Companies must establish systems to calculate, verify, and report embedded emissions in their products.

Industries most affected include aluminum production, steel manufacturing, and cement production. These sectors must invest in emissions measurement systems and potentially carbon reduction technologies to remain competitive.

Logistics Sector Implications

Freight forwarders and customs brokers face increased documentation requirements. CBAM declarations require detailed emissions data that must flow through the supply chain alongside traditional trade documentation.

New service opportunities emerge for logistics providers offering CBAM compliance support, emissions calculation assistance, and documentation management.

Preparation Strategies

Exporters should begin emissions measurement and reporting systems now, even before full implementation. Understanding your carbon footprint enables informed decisions about decarbonization investments.

Engaging with EU importers to understand their CBAM compliance processes ensures smooth trade continuation. Joint planning can identify opportunities to optimize documentation flows and reduce compliance costs.

The Broader Context

CBAM signals a fundamental shift in trade policy toward incorporating environmental costs. Other jurisdictions are considering similar mechanisms, making carbon measurement and management a core business competency.

Early movers who develop robust emissions tracking and reduction capabilities will gain competitive advantages as carbon border adjustments become more widespread globally.
