The European Union’s introduction of a carbon border tax is emerging as one of the most consequential regulatory changes for Serbia’s export economy. Known as the Carbon Border Adjustment Mechanism (CBAM), the policy is designed to ensure that imported goods entering the EU face the same carbon costs as products manufactured within the bloc under the EU’s emissions trading system.
For Serbia, whose industrial exports remain closely integrated with European markets, the mechanism represents both a financial risk and a strategic turning point for the country’s manufacturing and energy sectors.
CBAM effectively places a price on the carbon emissions embedded in certain imported goods. Companies that import these products into the EU must purchase CBAM certificates corresponding to the CO₂ emissions generated during production, aligning the cost with the carbon price paid by European producers under the EU Emissions Trading System (EU ETS).
The policy initially targets a group of carbon-intensive sectors that are highly exposed to international trade. These include iron and steel, aluminum, cement, fertilizers, electricity and hydrogen, industries that form the backbone of heavy manufacturing across Europe and its neighboring economies.
Although the tax is formally paid by EU importers rather than exporters themselves, the economic burden ultimately flows back through the supply chain. Exporters from countries outside the EU—such as Serbia—must provide detailed emissions data for their products, and higher carbon intensity will translate into higher costs for their European buyers.
This dynamic has placed Serbia’s industrial exporters under increasing pressure.
Many of the country’s largest export sectors rely on energy-intensive production processes, particularly in metals, chemicals and electricity generation. Because Serbia’s electricity system still relies heavily on coal-fired power plants, the carbon intensity of domestic industrial production is often higher than the European average.
Analysts estimate that €9–10.5 billion of Serbia’s exports to the EU are connected to sectors directly or indirectly exposed to CBAM rules, highlighting the scale of the potential impact on the country’s trade structure.
The financial implications could be significant. Carbon prices in the EU’s emissions trading system have fluctuated around levels that can reach up to about €85 per tonne of CO₂, meaning that high-emission products imported into the EU may face substantial additional costs.
For companies operating in competitive international markets, such cost increases could reduce profit margins or erode price competitiveness relative to producers located inside the EU.
The mechanism is being introduced gradually. The EU launched a transitional phase that required companies to begin reporting emissions associated with imported products, while the financial obligations will begin to apply fully from 2026 onward, with importers required to submit CBAM certificates reflecting those emissions.
In response, Serbia has begun aligning its own regulatory framework with the emerging European system.
At the start of 2026, the country introduced a national carbon tax of €4 per tonne of CO₂ emissions, applying to greenhouse gases emitted by domestic industries. The aim is to gradually introduce carbon pricing within Serbia’s economy while reducing the eventual CBAM liability faced by Serbian exports entering the EU.
Under CBAM rules, carbon costs already paid in the exporting country can be deducted from the amount owed in the EU. The introduction of a domestic carbon price therefore allows Serbian companies to offset part of the EU charge, preventing double taxation of the same emissions.
Nevertheless, the difference between Serbia’s initial carbon price and the much higher price of EU emissions allowances remains substantial. As a result, Serbian exporters will still face a significant carbon cost gap unless the country gradually aligns its pricing with the European system.
The sectors most directly affected are those already exposed to intense competition in European markets.
Steel and aluminum producers are among the most vulnerable, as these industries are both energy-intensive and highly dependent on exports. Fertilizer production—another carbon-heavy sector—also falls directly within the scope of the mechanism.
Electricity exports present a particularly complex case.
Because Serbia’s power generation relies heavily on coal-fired plants, electricity sold into the EU may carry a high carbon intensity. Studies estimate that CBAM-related carbon costs for electricity exports from Western Balkan countries could reach around €60–70 per megawatt-hour, potentially reshaping regional power trade flows.
This could reduce the competitiveness of coal-based electricity exports while increasing incentives for renewable power generation.
Beyond the immediate financial impact, CBAM is likely to trigger deeper structural changes across Serbia’s industrial landscape.
Export-oriented companies will need to invest in cleaner production technologies, energy efficiency improvements and renewable electricity sourcing in order to remain competitive in the European market. Without such investments, the carbon cost embedded in exported products could become an increasingly significant barrier to trade.
At the same time, the mechanism may also create opportunities for companies that successfully decarbonize their operations.
European manufacturers are under growing pressure to reduce emissions across their supply chains. Suppliers capable of demonstrating low-carbon production processes may therefore gain an advantage as EU companies seek to minimize the carbon footprint of their inputs.
For Serbia’s policymakers, CBAM is forcing a broader reconsideration of the country’s energy strategy.
The domestic power system remains heavily dependent on lignite-fired coal plants, which generate the majority of Serbia’s electricity. While these facilities provide energy security, their high carbon intensity increases the embedded emissions of industrial products manufactured using Serbian electricity.
Accelerating the development of renewable energy sources and modernizing the electricity grid will therefore be essential if Serbian industry is to remain competitive under the new European regulatory framework.
In that sense, CBAM represents more than a trade measure. It is effectively exporting the EU’s climate policy beyond its borders, compelling neighboring economies to align their industrial systems with Europe’s decarbonization agenda.
For Serbia’s export-driven industries, the mechanism marks the beginning of a long and complex transition. Companies that fail to adapt to a carbon-priced global economy may gradually lose access to their most important market.
Those that succeed in reducing emissions, however, could find themselves better positioned in a European industrial landscape increasingly defined by the cost of carbon.
