CBAM moves from reporting to payments
The Carbon Border Adjustment Mechanism entered its definitive phase on 1 January 2026, introducing carbon pricing on selected goods imported into the EU. The system is intended to align the carbon cost of imports with the cost borne by EU producers under the EU Emissions Trading System. Sectors considered vulnerable to carbon leakage include steel, aluminium, cement, fertilisers and electricity—industries where Serbian production has meaningful export exposure to Europe.
During the transitional period from October 2023 to December 2025, importers were required to report embedded emissions without paying carbon costs. From 2026 onward, EU importers must purchase CBAM certificates corresponding to embedded emissions in imported goods. The first formal financial declaration is scheduled for September 2027, covering imports made during 2026.
Engineering readiness becomes a trade requirement
For exporters in Serbia, the practical implication is that 2026 functions as the final preparation window before carbon costs begin to affect trade relationships more directly. This compresses the time available for technical project development: companies must translate plant-level energy and process data into verified emissions figures that can be used in EU declarations. The operational burden therefore moves upstream into exporter-controlled systems and documentation flows.
CBAM compliance depends on calculating embedded carbon emissions associated with imported goods and linking those calculations to certificate purchases by EU importers. Certificate pricing tracks prevailing EU carbon allowance prices, which have traded roughly in the range of €70 to €90 per tonne of CO₂ in recent years. For energy-intensive producers, this effectively turns carbon intensity into a production-cost variable that can influence contract competitiveness.
Structural exposure: lignite-based power and indirect emissions
A central engineering challenge is structural rather than purely procedural. Serbia’s electricity system relies heavily on electricity generated from lignite-fired power plants operated primarily by Elektroprivreda Srbije (EPS). Lignite remains the dominant fuel providing baseload power while also producing high carbon emissions.
Because electricity carbon intensity feeds directly into embedded emissions for exported industrial products, the same generation profile can increase CBAM-relevant footprints across multiple product categories. Once those emissions are priced according to EU carbon market dynamics, competitiveness can deteriorate quickly for exporters whose production relies on high-emission electricity inputs.
From monitoring plans to verified data
The first technical step for exporters is developing installation-level emissions accounting systems capable of measuring both direct and indirect emissions tied to production. Direct emissions relate to fuel combustion within industrial processes, while indirect emissions reflect the carbon intensity of electricity consumed during production. Given Serbia’s coal-dominant generation mix, indirect emissions can represent a substantial share of total product footprints.
Under CBAM rules, exporters that cannot provide verified emissions data risk being assigned default emission values by EU authorities. These default values are intentionally conservative and often higher than actual levels, which can translate into artificially inflated carbon costs. To avoid this outcome, companies need credible monitoring systems aligned with the EU Monitoring and Reporting Regulation used within the EU ETS framework.
Verification workflows enter EPC-style scope
Monitoring is only one part of the compliance chain; verification is the second major component. Emissions data submitted for CBAM purposes must be verified by accredited third-party auditors who assess whether approved methodologies were followed and whether underlying data are reliable and traceable. For exporters, this adds an operational step that must run alongside traditional export documentation such as product specifications, invoices and customs declarations.
This effectively changes how engineering teams structure project execution readiness: measurement equipment selection, energy-consumption recording practices, and process documentation must be designed so they can withstand independent verification. In practical terms, CBAM turns emissions accounting into a core element of international trade documentation rather than a standalone environmental reporting exercise.
Power procurement as a decarbonisation lever
While CBAM obligations formally sit with EU importers, those importers depend on exporters for reliable emissions information to complete declarations. Exporters that cannot supply verified data may face difficulty maintaining contracts with European buyers. At the same time, CBAM creates a measurable incentive for lower-carbon production pathways that reduce embedded emissions per unit output.
Reducing carbon intensity can be achieved through energy efficiency improvements that lower fuel consumption per unit of output and through fuel switching away from coal toward natural gas or electrified processes to reduce direct emissions. A particularly fast pathway highlighted for CBAM readiness is renewable electricity sourcing: exporters can enter long-term power purchase agreements with renewable producers securing electricity generated from wind, solar or hydropower. Serbia has also begun introducing renewable energy auctions aimed at expanding wind and solar generation, which can support broader availability of low-carbon supply options.
Investment timing: 2026 preparation versus 2027 financial impact
The financial implications of these strategies are tied to carbon intensity rather than production volume alone. Lower embedded emissions reduce the number of CBAM certificates EU importers must purchase for covered goods, which matters most for exporters operating on narrow margins where small changes in footprint can affect competitiveness in EU markets. With financial obligations fully materialising in 2027 after preparation during 2026, companies treating CBAM as distant regulatory work risk arriving too late for effective technical remediation.
For developers and industrial investors planning upgrades across steel, aluminium, cement, fertilisers and electricity-linked value chains, CBAM readiness should be treated as an integrated front-end scope: monitoring system design, verification-ready data governance, and low-carbon power procurement strategies need coordinated CAPEX planning and execution scheduling. In broader industry terms, export competitiveness will increasingly depend not only on labour costs, logistics or productivity but also on measured carbon intensity—making CBAM a structural transformation of how industrial trade with Europe is engineered.
