The implementation of the European Union’s Carbon Border Adjustment Mechanism (CBAM) is set to significantly alter energy trade dynamics for the Western Balkans. As of January 1, 2026, this mechanism will require that imports of carbon-intensive goods into the EU reflect the same carbon costs faced by European producers. This regulatory shift extends the EU’s carbon pricing beyond its borders, fundamentally changing how emissions are treated in international trade.
In anticipation of CBAM’s rollout, the European Commission has indicated a willingness to adapt certain provisions, particularly concerning electricity imports. These adjustments aim to mitigate potential disruptions in regional energy markets that are tightly interconnected with the EU grid. However, despite these transitional measures, the long-term implications for the region’s power sector are profound.
CBAM primarily targets sectors such as steel, cement, fertilisers, aluminium, hydrogen, and electricity. For Western Balkan economies—where exports to the EU constitute a significant portion of industrial output—this introduces a new cost structure directly linked to carbon intensity. Between 2014 and 2023, these countries exported approximately 109 terawatt-hours (TWh) of electricity to the EU, accounting for about 15.5% of their total generation. Notably, around 57% of this electricity is derived from coal, placing it at high risk under CBAM regulations.
The immediate consequence of CBAM is projected pricing pressure on electricity exports. Estimates indicate that related costs could reach €60–70 per megawatt-hour (MWh) for countries like Serbia and Montenegro. Such cost increases threaten to eliminate historical profit margins in EU markets and compel EU importers to pivot towards lower-carbon energy sources from within the bloc or compliant external suppliers.
This shift in pricing dynamics is already reshaping trade strategies. Electricity exports that were previously driven by marginal cost advantages associated with lignite generation now face structural disadvantages. Effectively, CBAM acts as a filter that favors low-carbon electricity in cross-border trade with the EU.
Utilities in the region must also contend with compressing revenue streams tied to export arbitrage, particularly in coal-dependent systems such as Bosnia and Herzegovina, North Macedonia, and parts of Serbia. Analysts predict a sharp decline in export volumes as EU buyers internalize CBAM-related costs.
Moreover, CBAM is influencing investment signals across the region. Projects reliant on lignite or other high-emission fuels are expected to face a deteriorating outlook as CBAM accelerates their obsolescence. In contrast, renewable energy projects—including wind, solar, and flexible hydro—are gaining importance as viable “CBAM-compatible” export options.
This policy shift introduces a new fiscal landscape; if Western Balkan nations align their domestic carbon pricing with EU standards, they stand to retain carbon revenues locally instead of transferring them through CBAM payments. Projections suggest that such domestic systems could yield billions of euros annually, providing essential funding for energy transition initiatives.
As CBAM evolves from a mere trade barrier to a strategic policy tool, governments face critical decisions: either absorb external costs that diminish competitiveness or internalize carbon pricing while redirecting revenues toward modernizing grids and decarbonizing industries.
Electricity remains central to this transition. Unlike industrial goods, power flows react swiftly to price changes, and historically, the Balkan region has depended on cross-border trading with EU markets such as Italy, Hungary, Romania, and Greece. Under CBAM regulations, these electricity flows will increasingly hinge on carbon intensity metrics, altering dispatch economics significantly.
The European Commission’s readiness to consider transitional measures for electricity imports highlights the complexities involved. The physical integration of regional power systems with the EU grid means abrupt changes could pose security-of-supply risks for both parties.
Ultimately, CBAM represents not a temporary measure but a structural extension of EU climate policy into neighboring regions. For Balkan economies, compliance with EU carbon frameworks is becoming essential not just for accession negotiations but also for maintaining access to lucrative EU markets.
This evolving landscape indicates that competitiveness is no longer defined solely by financial metrics but increasingly by carbon intensity considerations embedded in pricing structures and investment decisions. The ability to deliver low-carbon electricity and products will be crucial for Western Balkan nations as they navigate this immediate economic constraint shaping their export strategies.
