The EU’s Carbon Border Adjustment Mechanism is moving from design to implementation, forcing companies that trade carbon-intensive goods to confront how embedded emissions travel across borders. For exporters tied into EU supply chains, the compliance burden begins with reporting and certificate purchases linked to EU ETS pricing. For domestic producers, the policy also sharpens a strategic question: can power and industrial processes be decarbonized fast enough to protect market access?
CBAM implementation timeline and covered sectors
From 2026 onward, EU importers of carbon-intensive products must account for embedded emissions in goods imported from outside the EU and purchase CBAM certificates priced according to the EU Emissions Trading System. The mechanism initially covers iron and steel, aluminium, cement, fertilizers, electricity, and hydrogen. That scope matters for regional exporters because it aligns with industrial categories that feed directly into European construction, infrastructure, and manufacturing demand.
Although CBAM is applied through importers in the EU market, the operational impact is felt upstream by producers that must supply credible emissions data and face potential competitiveness shifts. The regulatory logic ties border costs to carbon intensity, making production pathways and energy sourcing central to trade outcomes.
Serbia’s export exposure: where CBAM-linked costs can surface
Serbia’s industrial footprint is tightly integrated with European manufacturing supply chains, which increases the likelihood that carbon pricing at the EU border will transmit into Serbian export revenues. Estimates indicate that €9–10.5 billion of Serbia’s exports to the EU are associated with CBAM-exposed sectors or supply chains. That scale implies indirect exposure for a broad set of intermediate materials used in EU value chains.
Steel from Smederevo and cement from plants across central Serbia are among the most visible channels into EU construction and industrial procurement. Fertilizer and chemical output also intersects with European agriculture and chemical markets, while electricity-related considerations can affect how energy-intensive production is valued when low-carbon power becomes scarce or expensive.
Energy constraints: lignite dominance meets carbon pricing pressure
A key determinant of how CBAM affects Serbian industry is not only product emissions but also the carbon profile of the electricity system powering production. Electricity generation remains dominated by lignite-fired plants operated by EPS, which historically supplied inexpensive but high-emission power to heavy industry. Coal accounts for around 60–65 percent of generation, hydropower provides roughly a quarter, and wind, solar, and gas remain relatively minor contributors.
This structure creates a tension for exporters: they face increasing carbon pricing pressure in EU markets while relying on an electricity mix whose emissions profile is among the highest in Europe. In practice, that means decarbonization efforts must extend beyond end-of-pipe measures to include energy procurement strategies and grid-connected renewable expansion.
Steel under scrutiny: Smederevo’s production route and transition options
The most prominent CBAM-exposed case in Serbia is HBIS Group’s steel plant in Smederevo, described as Serbia’s largest industrial exporter and one of Southeast Europe’s major steel facilities. The plant produces flat steel products widely exported to EU markets and integrated into automotive, construction, and industrial supply chains. Its primary technology relies on the blast furnace–basic oxygen furnace route, dependent on coal-based inputs and associated with relatively high CO₂ emissions compared with electric arc furnace technologies.
As CBAM-linked costs rise for imported steel over time, competitiveness could be influenced by both direct production emissions and the carbon intensity of electricity used throughout manufacturing. The compliance challenge therefore connects process choice—such as increased scrap recycling through electric arc furnaces—with access to lower-emission electricity.
Cement exposure: clinker chemistry, alternative fuels, and plant-level relevance
Cement is among the most carbon-intensive industrial activities covered by CBAM due to both fuel combustion and chemical reactions involved in clinker production. Serbia’s cement sector includes three major integrated plants operated by multinational corporations: Holcim Serbia in Beočin; Moravacem in Popovac; and Titan Cementara Kosjerić near Kosjerić. Holcim has implemented sustainability initiatives including environmental product declarations alongside investments aimed at reducing emissions intensity.
Moravacem produces approximately 1.35 million tons of cement annually, while Titan Cementara Kosjerić contributes roughly 750,000 tons per year. Each plant supplies domestic or regional construction markets that can ultimately reach EU buyers through trade flows subject to CBAM reporting obligations. Decarbonization strategies typically include reducing clinker content in finished cement, increasing alternative fuels such as biomass or industrial waste, and improving kiln energy efficiency—approaches already being pursued across multinational portfolios.
Fertilizers and chemicals: indirect exposure through energy-intensive processes
Beyond steel and cement, fertilizer manufacturing can face significant emissions linked to natural gas use and energy-intensive ammonia synthesis processes. Companies such as Elixir Group operate fertilizer and phosphate production facilities in Serbia and may encounter indirect CBAM exposure depending on export destinations and how supply chains connect with EU agriculture and chemical demand.
For policy monitoring purposes, this highlights a broader compliance pattern: even where a product’s inclusion depends on CBAM scope at import level, upstream energy use can determine embedded emissions profiles used for reporting under EU ETS-linked certificate pricing.
Electricity supply dynamics: renewables expansion versus grid limits
Serbia’s ability to reduce embedded emissions hinges on whether low-carbon electricity can scale quickly enough for energy-intensive industry. The government has launched a renewable energy expansion program aimed at diversifying generation away from coal, supported by international financial institutions including the European Bank for Reconstruction and Development. Competitive renewable auctions are a cornerstone of this strategy.
The second auction round launched in 2024 allocated capacity for 300 megawatts of wind power and approximately 125 megawatts of solar photovoltaic projects under 15-year contracts for difference designed to stabilize revenues. The broader plan targets roughly 1,300 megawatts of new renewable capacity within three years, with strong investor interest evidenced by more than forty proposed projects in that second round—bids exceeding available quotas for both wind and solar.
Corporate procurement tools—and why scarcity could raise costs
Industrial exporters seeking verifiable low-emission power increasingly look toward corporate power purchase agreements that contract electricity directly from renewable producers. Such arrangements can help align manufacturing operations with lower-carbon electricity claims relevant to embedded emissions calculations under CBAM reporting requirements. However, near-term adequacy remains uncertain because heavy industry requires continuous power supply across steel mills, cement plants, and metal refineries.
Grid infrastructure also poses constraints: renewable projects must connect to transmission networks, while integrating intermittent wind and solar requires investments in modernization, balancing capacity, and potentially storage solutions. The market risk extends further if green electricity becomes a premium commodity regionally; Serbia exports electricity to neighboring countries, so scarce low-carbon power could be sold externally rather than supplied domestically—potentially increasing costs for exporters trying to reduce CBAM-linked footprints.
Green metals by 2030: minerals advantage meets decarbonization requirements
Despite these constraints, Serbia has structural advantages that could support longer-term movement toward green metals production by 2030 if energy policy aligns with industrial investment needs. The country hosts significant mineral resources including copper deposits increasingly relevant amid global electrification trends. Mining operations in eastern Serbia already supply metals used in electrical infrastructure and renewable technologies.
European manufacturers are also seeking low-carbon sources of industrial materials such as green steel, green aluminium, and low-carbon copper to meet their own climate targets. While copper itself is not currently included among CBAM’s initial covered materials list, smelting and refining electricity intensity means associated production emissions could become relevant if CBAM expands toward downstream metal products or broader categories of industrial materials.
Compliance implications across the value chain
CBAM introduces new costs and compliance obligations for exporters tied to covered sectors including steel, cement, fertilizers, electricity-related flows where relevant data is required downstream, aluminium where applicable through trade channels into EU markets, and hydrogen where supply chains connect into EU demand. In practical terms for importers operating under EU ETS-aligned certificate pricing from 2026 onward, reporting accuracy depends on credible embedded emissions data that reflects both process routes and electricity carbon intensity.
For industry operators in Serbia’s export-oriented segments—especially those reliant on lignite-heavy power—renewables expansion plans via auctions provide a pathway but do not remove near-term uncertainty around availability of low-carbon electricity during early implementation years. The broader implication is straightforward: maintaining competitiveness will require coordinated action across energy procurement capacity building, process modernization choices such as scrap-based routes in steelmaking where feasible, kiln fuel switching strategies in cement production, and regulatory readiness for carbon accounting systems that can withstand CBAM scrutiny at the border.
