The European Commission’s finalization of the implementing package for the Carbon Border Adjustment Mechanism marks a structural shift in the way carbon costs will be calculated, allocated, and ultimately mitigated for goods imported into the European Union. As of 1 January 2026, CBAM moves from a transitional reporting regime into its definitive financial phase, transforming embedded emissions from a disclosure obligation into a direct cost item tied to EU carbon pricing.
The most consequential element of the new framework is the clarified treatment of indirect emissions, particularly those arising from electricity consumed during industrial production. Under the finalized rules, importers are permitted to reduce their CBAM liability where they can credibly demonstrate that production relied on electricity with a lower carbon intensity than the default grid emission factor. This marks a decisive departure from purely accounting-based approaches and anchors CBAM compliance in demonstrable physical energy flows.
At the center of this evidentiary architecture sit physical power purchase agreements, structured around real electricity delivery and strict temporal alignment. The Commission’s approach explicitly prioritizes actual supply over contractual attribution. To qualify for emissions reductions under CBAM, electricity sourcing must be supported by verifiable PPA contracts that directly link the electricity producer in the third country with the authorized CBAM declarant importing the goods into the EU. These contracts must be accompanied by evidence of a genuine technical connection between the generation asset and the industrial installation, eliminating the possibility of purely notional or portfolio-based arrangements.
Equally critical is the requirement for granular measurement. Smart metering data must confirm that electricity generated by the contracted asset was delivered and consumed within the same hourly measurement interval as industrial production. This hourly matching requirement effectively aligns CBAM with the most stringent interpretations of additionality and temporal correlation, pushing industrial decarbonization beyond annual averages and into operational reality.
In parallel, the implementing rules make clear what will not be accepted. Energy attribute certificate systems, including Guarantees of Origin and I-REC instruments, are explicitly excluded from recognition for CBAM purposes. This exclusion underscores the Commission’s insistence on physical decarbonization rather than virtual claims. For exporters, the implication is unambiguous: paper green electricity is insufficient; only physically delivered, time-matched clean power can reduce embedded emissions under CBAM.
The economic consequences of this shift are substantial. Producers of carbon-intensive goods exporting into the EU now face a choice between absorbing rising CBAM costs linked to EU ETS prices or structurally reducing their exposure by securing low-carbon electricity for production. For electricity-intensive sectors such as steel, aluminium, cement, fertilizers, and basic chemicals, the differential between default grid emissions and physically sourced renewable power can translate into material cost savings per tonne of product, directly affecting margins and competitiveness in EU markets.
These dynamics are particularly relevant for South-East European markets outside the EU, including Albania, Kosovo, Serbia, Montenegro, and North Macedonia. In these jurisdictions, PPA markets remain underdeveloped, grid structures are often centralized, and industrial electricity supply has historically been dominated by utility tariffs rather than bilateral contracts. CBAM introduces an external price signal that effectively exports EU carbon discipline across the EU’s industrial supply chain, regardless of national climate policy alignment.
For industry in the region, CBAM compliance is no longer a downstream customs issue but an upstream energy-procurement challenge. Long-term, physically settled PPAs with renewable generators become strategic instruments, not only for decarbonization but for market access. For power producers and developers, this creates a structurally new source of demand: industrial offtakers willing to commit to long-duration contracts with strict delivery and metering requirements in exchange for carbon cost mitigation.
As a result, CBAM is emerging as a powerful catalyst for new renewable capacity in non-EU South-East Europe, particularly projects capable of direct or quasi-direct physical supply to industrial sites. Grid-connected assets with constrained curtailment risk, proximity to large industrial loads, and the ability to support high-resolution metering are likely to command a premium. The traditional separation between industrial investment decisions and power-sector development is eroding under CBAM pressure.
CBAM can no longer be understood merely as a climate regulation. It functions as an economic coordination mechanism that reshapes relationships between industry, electricity markets, and renewable energy finance. For exporters to the EU, the ability to structure compliant physical PPAs will increasingly determine carbon cost exposure, competitive positioning, and long-term viability in European value chains. For South-East Europe, the mechanism accelerates a transition from tariff-based electricity supply toward contract-driven, investment-backed decarbonization, with lasting implications for industrial competitiveness across the region.
For Serbia, the definitive phase of CBAM arrives at a moment when the country’s export-oriented industrial base remains structurally exposed to carbon pricing despite the absence of a domestic ETS. Steel, aluminium, copper processing, fertilizers, cement, and basic chemicals together account for a dominant share of Serbia’s non-EU industrial exports to the European Union, while electricity for these sectors is still overwhelmingly sourced from a lignite-heavy national power system. The default grid emission factor applied under CBAM therefore translates into a material carbon cost embedded in Serbian exports from 2026 onward, irrespective of national climate policy.
This is where the Commission’s clarified treatment of indirect emissions fundamentally alters Serbia’s industrial calculus. The ability to demonstrate lower-carbon electricity input through physically delivered power becomes the only credible pathway to reduce CBAM exposure without relocating production. For Serbian producers, CBAM compliance shifts from a customs and reporting function to a core operational decision tied to energy procurement, grid access, and long-term contracting.
Serbia’s electricity mix remains dominated by lignite-fired generation operated by the national utility, with hydropower providing variability and renewables still representing a limited share of total dispatchable capacity. Under CBAM rules, reliance on this average grid mix results in the application of a high default emission factor for electricity-related indirect emissions. For energy-intensive exporters, this translates directly into higher CBAM certificate requirements, increasing unit costs and eroding competitiveness against EU-based producers already internalizing ETS prices but benefiting from cleaner grids or on-site renewable supply.
The implementing package effectively creates a premium for Serbian industrial facilities capable of structurally separating their electricity supply from the national average. Physical PPAs with renewable generators, supported by hourly matched metering and demonstrable delivery, become instruments of industrial risk management rather than optional sustainability tools. In Serbia’s context, this strongly favors renewable projects that can establish a clear technical and contractual nexus with specific industrial offtakers, either through direct grid connections, dedicated feeder arrangements, or priority allocation within distribution or transmission nodes serving industrial zones.
The exclusion of Guarantees of Origin and I-REC certificates is particularly consequential for Serbia. While several Serbian exporters have explored certificate-based green electricity claims to satisfy corporate ESG requirements, CBAM renders these approaches economically irrelevant. From 2026, only physically supplied electricity reduces embedded emissions. This invalidates purely financial or reputational decarbonization strategies and forces Serbian industry toward tangible infrastructure-linked solutions.
From an investment perspective, CBAM introduces a new layer of bankability into Serbia’s renewable energy pipeline. Long-term, fixed-price physical PPAs with industrial offtakers exporting to the EU provide revenue stability that can support project financing even in the absence of a domestic ETS or mature merchant market. For lenders and equity investors, the CBAM-driven willingness of industrial buyers to commit to time-matched PPAs changes the risk profile of Serbian renewable assets, particularly wind and utility-scale solar projects located near large industrial loads or grid substations serving export-oriented manufacturing clusters.
The timing is critical. Serbia’s renewable expansion plans remain ambitious on paper, but grid congestion, permitting delays, and uncertainty around market design have slowed execution. CBAM acts as an external enforcement mechanism, effectively importing EU carbon discipline into Serbian energy planning. Industrial exporters facing rising CBAM costs will increasingly pressure policymakers, grid operators, and utilities to enable direct access to renewable supply, clearer rules for bilateral contracting, and investment in metering infrastructure capable of supporting hourly matching.
For heavy industry, the economics are stark. The difference between paying CBAM certificates priced in line with EU ETS allowances and securing lower-carbon electricity through a compliant physical PPA compounds over multi-year horizons. For large exporters, CBAM exposure quickly reaches levels comparable to core production margins, turning energy sourcing into a board-level issue. In this environment, decarbonization becomes inseparable from competitiveness, financing costs, and long-term contract pricing with EU customers.
CBAM also alters Serbia’s position within regional energy markets. While neighboring EU member states increasingly decarbonize their grids, Serbia risks becoming a high-carbon outlier unless it accelerates renewable deployment tied directly to industrial demand. Conversely, if Serbia succeeds in structuring CBAM-compliant physical PPAs, it can preserve its role as a near-shoring hub for EU supply chains while simultaneously attracting capital into generation assets designed around industrial offtake rather than volatile merchant exposure.
CBAM will function in Serbia as a de facto shadow carbon price applied at the border but felt at the factory gate. The mechanism rewards industrial actors that internalize energy system transformation and penalizes those that rely on legacy grid averages. In practical terms, CBAM pushes Serbian industry, power producers, financiers, and policymakers into a shared optimization problem where electricity sourcing, grid infrastructure, and export competitiveness converge. The structuring of physical, time-matched PPAs is no longer an emerging best practice; it becomes a prerequisite for maintaining Serbia’s industrial relevance within EU-centric value chains.
