EU climate policy is increasingly shaping how industrial goods compete across borders, with carbon costs becoming a trade variable rather than a purely regulatory one. For Serbian producers selling into the European market, the Carbon Border Adjustment Mechanism (CBAM) is moving from compliance planning to operational preparation. The shift matters most for products tied to high-emissions production and electricity generation.
Definitive CBAM carbon pricing starts on 1 January 2026
CBAM entered its definitive phase on 1 January 2026, introducing carbon pricing on selected goods imported into the EU. The mechanism is designed to align the carbon cost of imports with the cost borne by EU producers under the EU Emissions Trading System (EU ETS). Sectors covered include steel, aluminium, cement, fertilisers and electricity, all areas where Serbian exporters have meaningful exposure to European demand.
Implementation is structured around reporting and later financial obligations. During the transitional period from October 2023 to December 2025, importers reported embedded emissions without paying carbon costs. The definitive phase beginning in 2026 adds the financial component, requiring EU importers to purchase CBAM certificates linked to embedded emissions in imported goods.
September 2027 marks the first financial declaration for 2026 imports
While certificate purchasing begins with the definitive phase in 2026, the first formal financial declaration is scheduled for September 2027. That submission will cover imports made during 2026. For exporters outside the EU ETS system, this timetable effectively creates a narrow window to ensure that emissions data can be supplied in time for downstream declarations.
Market participants describe 2026 as the final preparation window before CBAM costs begin to fully affect trade relationships. The practical impact is that exporters must be able to provide credible emissions information that EU importers can use for CBAM calculations and certificate procurement.
Electricity intensity becomes a central compliance risk
A key structural factor for Serbian industry is the carbon profile of domestic power generation. Serbia’s industrial base relies heavily on electricity produced from lignite-fired power plants operated primarily by Elektroprivreda Srbije (EPS). Lignite remains dominant in Serbia’s electricity system, supplying baseload power while generating high emissions.
Under CBAM rules, that electricity carbon intensity can translate directly into higher embedded emissions for exported industrial products. Once those emissions are priced through the EU carbon market, competitiveness can change quickly—especially where margins are tight and product prices are sensitive to additional cost components.
Certificate costs track EU ETS allowance prices
The CBAM calculation framework requires EU importers to determine embedded carbon emissions associated with imported goods and purchase certificates reflecting those emissions. The certificate price corresponds to prevailing prices of EU ETS allowances. In recent years, those allowances have traded roughly in the range of €70 to €90 per tonne of CO₂.
For energy-intensive exporters, this linkage means carbon costs function as an additional production-related expense rather than a separate compliance fee. Where embedded emissions are high, the resulting cost embedded in product pricing may erode the margin needed to compete with EU producers operating under EU ETS obligations.
Verified emissions data and default values shape exporter responsibilities
CBAM preparation requires more than estimating footprints; it depends on installation-level accounting systems capable of measuring both direct and indirect emissions linked to production. Direct emissions stem from fuel combustion within industrial processes, while indirect emissions reflect the carbon intensity of electricity consumed during production. Given Serbia’s coal-dominated power mix, indirect emissions can represent a substantial share of total embedded emissions.
Exporters unable to provide verified emissions data face default emission values assigned by EU authorities. These default values are intentionally conservative and often higher than actual levels, which can lead to artificially inflated carbon costs for shipments where measurement and verification are weak.
Monitoring plans aligned with EU ETS rules and third-party verification
To avoid default assignments, companies need monitoring systems built around an emissions monitoring plan aligned with the EU’s Monitoring and Reporting Regulation—the same framework used within EU ETS implementation. This involves installing measurement equipment, recording energy consumption and documenting production processes so that calculations can be independently verified.
A second compliance step is verification by accredited third-party auditors. Verifiers assess whether methodologies follow approved approaches and whether underlying data are reliable and traceable. For exporters, this adds a new operational requirement: carbon data must accompany traditional export documentation such as product specifications, invoices and customs declarations.
Decarbonisation pathways: efficiency, fuel switching and renewable electricity
Although CBAM obligations fall on EU importers, they depend on exporters for reliable emissions inputs needed for declarations. Exporters that cannot supply verified data may find it harder to maintain contracts with European buyers as documentation requirements become part of commercial due diligence.
The same structure also creates incentives for lower-carbon production. Reducing carbon intensity can come through energy efficiency improvements that lower fuel use per unit of output, fuel switching away from coal toward natural gas or electrified processes that reduce direct emissions, and—most notably—renewable electricity sourcing that reduces indirect emissions.
Hydrogen inclusion signals broader Green Deal alignment
Beyond conventional heavy industries covered by CBAM categories such as cement, steel and aluminium, decarbonisation planning increasingly extends into emerging supply chains linked to low-carbon production pathways. Hydrogen is frequently referenced in industrial transition strategies alongside electrification and renewable power procurement as firms seek ways to reduce embedded emissions across value chains feeding covered sectors.
This broader alignment reflects how CBAM fits into the European Green Deal approach: using carbon pricing linked to EU ETS principles while pushing upstream producers toward measurable emission reductions that can be documented under verification rules.
Compliance implications for industry across Europe’s supply chain
The near-term regulatory focus is clear: reporting discipline during 2023–2025 transitions into financial responsibility starting in 2026, with first financial declarations due in September 2027 for imports made during that year. For exporters in cement, steel, aluminium, fertilisers and electricity-related supply chains—and for hydrogen-linked transition strategies—emissions measurement capability becomes a trading requirement rather than an internal sustainability exercise.
For EU importers operating under CBAM obligations alongside existing ETS frameworks, supplier data quality determines whether declarations can be completed without relying on conservative defaults. For EU producers already operating under EU ETS constraints, CBAM also functions as a competitive boundary-setting tool by bringing import-related carbon costs closer to those faced domestically under allowance pricing.
