CBAM compliance starts in 2026, targeting embedded emissions across key export sectors
Serbia’s industrial competitiveness is entering a new engineering and project-development phase as the EU Carbon Border Adjustment Mechanism moves from policy design to operational compliance. From 2026, EU importers of carbon-intensive goods must account for embedded emissions in imports from outside the EU and purchase CBAM certificates priced in line with the EU Emissions Trading System. The initial scope covers iron and steel, aluminium, cement, fertilizers, electricity, and hydrogen—sectors that align closely with Serbia’s export-linked industrial base.
Industry estimates place roughly €9–10.5 billion of Serbia’s exports to the EU in supply chains tied to CBAM-exposed sectors. For technical project developers and operators, this shifts carbon performance from a sustainability reporting topic into an input cost driver that can influence procurement decisions, contract structures, and investment timing across industrial facilities.
Energy-system carbon intensity becomes a constraint on decarbonization project readiness
Engineering plans for lower-carbon production in Serbia are constrained by the carbon intensity of the domestic electricity system that powers heavy industry. Electricity generation remains dominated by lignite-fired plants operated by the state utility EPS, with coal contributing around 60–65 percent of generation. Hydropower supplies roughly a quarter of output, while wind, solar, and gas remain comparatively minor contributors.
This creates a structural tension for exporters: EU carbon pricing pressures rise at the border while many production lines still rely on an electricity mix with emissions profiles among the highest in Europe. For developers preparing CAPEX programs—whether for process upgrades or renewable integration—grid availability and low-carbon supply contracting become as critical as plant-level technology selection.
Steel decarbonization focus: HBIS Smederevo faces blast-furnace emissions and electricity-carbon coupling
The most prominent CBAM-exposed case is the HBIS Group steel plant in Smederevo, Serbia’s largest industrial exporter and one of the largest steel facilities in Southeast Europe. The site produces flat steel products widely exported to EU markets and integrated into automotive, construction, and industrial supply chains. Its primary production route relies on the blast furnace–basic oxygen furnace process, which depends on coal-based inputs and typically carries higher CO₂ emissions than electric arc furnace pathways.
As CBAM progressively increases the carbon cost embedded in imported steel, competitiveness depends on both direct production emissions and the carbon intensity of electricity used across manufacturing steps. For EPC preparation and execution planning, this links process engineering choices—such as scrap utilization strategies—with power procurement design intended to reduce the effective emissions footprint of exported output.
Cement CAPEX planning: clinker reduction, alternative fuels, and kiln efficiency under CBAM pressure
Cement is among the most carbon-intensive industrial activities because it combines fuel combustion with 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 already started sustainability initiatives including environmental product declarations and 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 exports or indirectly supplies products that may reach EU markets subject to CBAM reporting obligations. Decarbonization strategies referenced for cement include reducing clinker content in finished cement, increasing alternative fuels such as biomass or industrial waste, and improving energy efficiency in kiln operations—measures that typically require coordinated engineering studies covering fuel handling systems, process control upgrades, and performance verification frameworks.
Fertilizers and chemicals: indirect exposure tied to ammonia synthesis energy demand
Beyond steel and cement, CBAM exposure can extend through fertilizer and chemical production where emissions arise from 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 impacts depending on export destinations and how supply chains connect with EU agriculture and chemical markets.
For technical project development teams, this raises questions about where decarbonization CAPEX is most effective—whether through energy-efficiency retrofits, fuel switching studies, or power procurement strategies that align with embedded-emissions accounting requirements used by EU buyers.
Copper supply chain implications: not covered initially, but electricity-driven emissions remain relevant
Mining and metal refining activities in eastern Serbia intersect with CBAM dynamics through electricity-intensive processing rather than direct inclusion of copper in the initial covered-material list. The Bor mining basin—operated by international investors—produces copper feeding European electrical and industrial supply chains. While copper itself is not currently included among covered materials at launch, electricity intensity of smelting and refining means production-related carbon emissions could become relevant if CBAM expands to downstream metal products or broader categories of industrial materials.
This matters for long-range engineering roadmaps because permitting timelines for power upgrades or process efficiency projects often outlast regulatory transitions. Developers preparing future-proof EPC scopes may need to design monitoring-ready systems capable of supporting evolving carbon-accounting requirements.
Renewable auctions accelerate capacity planning but grid integration determines delivery timelines
The availability of low-carbon electricity is positioned as a central determinant of whether Serbian exporters can maintain competitiveness under CBAM while transitioning toward lower-carbon metals by 2030. To address this constraint, Serbia has launched a renewable energy expansion program aimed at diversifying generation away from coal reliance. A cornerstone is competitive renewable energy auctions supported by international financial institutions including the European Bank for Reconstruction and Development.
The second auction round launched in 2024 allocated capacity for 300 megawatts of wind power and approximately 125 megawatts of solar photovoltaic projects. Developers received 15-year contracts for difference designed to stabilize revenues and attract investment. The broader strategy targets roughly 1,300 megawatts of new renewable capacity within three years—an aggressive schedule that increases the importance of front-end design readiness across grid connection studies, balancing requirements, and commissioning sequencing.
PPA structures become an engineering procurement lever for low-emission electricity access
Investor participation has been strong: more than forty renewable projects were proposed in the second auction round alone, with bids exceeding available quotas for both wind and solar power. Wind is described as the most mature technology with existing wind farms operating in northern regions such as Vojvodina, while solar momentum is increasing due to falling photovoltaic costs and improved market structures after earlier policy barriers.
For industrial exporters exposed to CBAM costs, corporate power purchase agreements are highlighted as a mechanism to secure low-carbon electricity through long-term contracting directly from renewable producers. In practical terms for procurement frameworks, PPAs can shape how operators structure delivery schedules against manufacturing load profiles—particularly important when heavy industry requires continuous power supply across steel mills, cement plants, and metal refineries.
Near-term risk: renewable scarcity during early CBAM years plus transmission modernization needs
Despite auction momentum, a key question remains whether enough renewable electricity will be available to supply energy-intensive industry in the near term as CBAM implementation begins. Even if renewable capacity expands quickly on paper, heavy industry demand can outpace low-carbon supply during early years when lignite generation still dominates system output. This affects not only operational delivery but also how developers justify CAPEX payback assumptions tied to reduced embedded emissions.
Grid infrastructure presents another execution constraint because renewable projects must connect to Serbia’s transmission network. Integrating large volumes of intermittent wind and solar requires significant investments in grid modernization, balancing capacity, and potentially energy storage technologies; without these upgrades renewable generation may be constrained even after technical completion. The regional market dimension adds further complexity since Serbia exports electricity to neighboring countries; if low-carbon power becomes scarce domestically it could be sold externally at higher value, increasing costs for exporters seeking renewables-linked reductions.
From compliance cost to green metals pathway: what changes by 2030 if studies translate into delivery
Serbia’s longer-term transition toward green metals is supported by structural advantages including mineral resources such as copper deposits increasingly valuable under global electrification trends. Mining operations already supply metals used in electrical infrastructure and renewable technologies, creating potential opportunities for vertically integrated low-carbon supply chains if energy-system decarbonization keeps pace with industrial modernization.
European manufacturers are also seeking low-carbon inputs including green steel, green aluminium, and low-carbon copper to meet climate targets. Achieving this transformation requires interlinked developments: expanding renewable electricity capacity beyond current levels; investing in modern production technologies that reduce emissions per unit output; and implementing regulatory frameworks supporting carbon accounting systems that allow Serbian exporters to demonstrate lower embedded emissions to EU buyers.
Broader project implications across steelmaking, cement kilns, fertilizers chemistry—and power system delivery
The introduction of CBAM marks a pivotal moment for Serbia’s industrial future by adding short-term compliance obligations for exporters while creating longer-term incentives for investment in renewable energy deployment and industrial modernization. For engineering teams preparing front-end studies and EPC-ready scopes across steel plants using blast furnace–basic oxygen routes, cement kilns requiring clinker reduction fuel strategy changes, fertilizer/ammonia processes dependent on natural gas-linked energy demand—and grid connection packages enabling wind and solar—the operational challenge is translating carbon-accounting needs into executable CAPEX programs.
If renewable expansion timelines align with grid modernization delivery and operators secure low-emission electricity access through contracting structures such as corporate PPAs while upgrading production technologies accordingly, Serbia could shift from exporting carbon-intensive traditional materials toward supplying lower-carbon metals and construction inputs over time toward 2030. The decisive factor remains execution readiness across energy policy implementation, industrial investment sequencing, permitting-aligned studies where needed for grid integration readiness—and regulatory reform enabling credible embedded-emissions documentation for EU buyers.
