Cement manufacturers in the Western Balkans can seek to reduce reported embedded emissions through qualifying renewable electricity arrangements under the EU Carbon Border Adjustment Mechanism (CBAM). The current definitive CBAM methodology for covered cement goods includes indirect electricity-related emissions, unlike most covered steel and aluminium products.
This feature gives electricity procurement a direct role in the regulatory emissions calculation. The impact of renewable power investments depends on eligible generation data, appropriate contractual arrangements, and reliable allocation of electricity consumption to individual cement products.
The largest emissions components in cement manufacturing are linked to clinker production, calcination, and thermal energy consumption. Renewable electricity can improve the reported carbon intensity of covered products, but it does not replace measures addressing direct process emissions and kiln fuel consumption.
For export-oriented producers, the investment task is to combine electricity-related improvements with clinker and process decarbonisation while maintaining evidence aligned with the applicable CBAM methodology. Electricity-related changes therefore need to be supported by documentation that fits the CBAM calculation approach.
Clinker, calcination and electricity use different emissions controls
Cement manufacturing includes multiple production stages with different energy requirements and emissions characteristics. Calcination during clinker production generates substantial direct carbon dioxide emissions through the chemical transformation of raw materials.
Thermal energy used in kiln operations is another major component of the sector’s carbon intensity. Electricity consumption is associated with activities including grinding, conveying, fans, mills, and shared utility systems.
Because these processes contribute differently to reported emissions results, manufacturers need to distinguish between clinker, individual cement types, and other relevant production outputs. The monitoring system should connect electricity consumption to applicable production stages and allocate shared energy use consistently.
Reliable production volumes and clinker-to-cement ratios are also required because changes in product composition can affect embedded emissions intensity even when overall site energy consumption remains relatively stable. Where product mix shifts occur, embedded emissions calculations can change independently of total site electricity use.
Eligible renewable arrangements require CBAM-aligned measurements
Covered cement products can benefit from lower eligible electricity emissions factors when manufacturers meet requirements under the applicable CBAM methodology. Potential arrangements include on-site solar photovoltaic generation, direct technical connections, and qualifying physical power purchase agreements (PPAs).
The generation and consumption measurements relevant to the methodology must be preserved at required time intervals. The generating installation must provide verified emissions information that supports the calculation.
These requirements make the structure of electricity procurement agreements important for regulatory reporting. A conventional annual purchase of renewable electricity certificates may support other corporate renewable energy claims but is not automatically sufficient evidence for an actual-value electricity calculation under CBAM.
The industrial buyer must identify which electricity quantities satisfy the methodology’s conditions rather than relying only on an annual renewable procurement percentage. This affects how much of total electricity use can be treated as eligible for CBAM purposes.
Grid imports and renewable shortfalls need separate MRV treatment
A cement factory operating under a long-term renewable electricity contract may still consume substantial quantities of grid electricity. Generation shortfalls, interruptions, or periods when renewable output does not match industrial demand can require additional electricity purchases.
The monitoring, reporting and verification (MRV) system should distinguish between qualifying renewable electricity consumption and volumes subject to applicable fallback emissions treatment. Applying a single renewable electricity factor across total annual consumption would not necessarily reflect the eligibility of the electricity used.
Separating these quantities allows management to evaluate how additional qualifying renewable supply could improve the reported indirect emissions component. It also provides a basis for assessing whether further procurement, storage, or operating adjustments would deliver sufficient value relative to their cost.
Efficiency measures and grinding operations affect both costs and indirect factors
Renewable electricity procurement should be coordinated with conventional industrial energy-efficiency measures. Grinding optimisation, high-efficiency electric drives, improved fan controls, and preventive maintenance can reduce electricity consumption per tonne of cement.
Lower energy demand provides operating-cost benefits while reducing the amount of renewable electricity needed to cover factory consumption. Where production schedules allow, selected electricity-intensive processes may be operated during periods with greater renewable electricity availability.
Cement plants with multiple grinding mills or production lines can examine differences in energy efficiency and allocate production accordingly. Using a more efficient mill during periods of abundant renewable generation may improve both electricity costs and the indirect emissions component if product quality and operating requirements are maintained.
Such operational changes should be evaluated using actual production data rather than assumptions about performance of individual manufacturing lines. This approach links any changes in electricity use to measurable output conditions relevant for evidence preparation.
Product mix changes embedded carbon intensity without changing total demand
Cement producers need to evaluate energy performance together with finished product composition. A cement product with a lower proportion of clinker may show lower embedded emissions because its direct process-emissions contribution is reduced.
Producing that cement may require additional grinding, potentially increasing electricity consumption per tonne. As a result, a single energy-intensity indicator could suggest deteriorating efficiency even while overall product emissions improve.
Management should assess electricity consumption alongside clinker content, production route, process emissions, and finished product quantities. The same principle applies when allocating electricity between quarry operations, clinker manufacturing, and cement production.
Where CBAM reporting boundaries require these activities to be distinguished, site-wide renewable electricity percentages may not adequately represent the electricity associated with individual covered products. Allocation methods therefore need to align with the relevant product-level boundaries used in the CBAM calculation.
Verification depends on complete installation-level evidence beyond power factors
A lower electricity emissions factor cannot compensate for missing or unreliable information concerning clinker production and direct industrial emissions. A verification-ready monitoring system needs to integrate raw-material records, kiln emissions, fuel consumption, measurable heat where relevant, electricity measurements, and manufacturing output.
These records must support embedded emissions calculations under appropriate product and production boundaries. Electricity data should therefore be part of a wider installation-level evidence system rather than treated as a separate renewable energy reporting exercise.
This structure allows independent reviewers to examine how direct process emissions, precursor or material information, thermal energy, and qualifying electricity consumption contribute to final reported results. Evidence integration supports consistency between direct emission inputs and indirect electricity-related components used in CBAM reporting.
Investment comparisons use cost per verified tonne under applicable methodology
Cement producers can compare decarbonisation investments based on expected cost and recognised emissions reductions under the applicable methodology. Potential measures include renewable electricity procurement, alternative kiln fuels, clinker substitution, waste heat recovery, and industrial process-efficiency improvements.
These options can differ in capital expenditure requirements, implementation needs, and potential emissions impact. Renewable electricity may address a smaller share of total cement footprint than measures reducing clinker-related emissions but can be quicker to implement and easier to verify.
A combined marginal abatement cost assessment allows management to compare costs for achieving a verified tonne of emissions reduction across different investments. This can support phased programmes that introduce electricity-related improvements while larger process-decarbonisation projects are developed.
Electricity evidence also matters for financing appraisals
The inclusion of eligible indirect electricity emissions in CBAM connects qualifying renewable arrangements with regulatory emissions performance for cement manufacturers. For lenders assessing a solar photovoltaic investment or physical PPA, manufacturers can demonstrate how electricity measurements and supporting generator information enter product-level emissions calculations.
The financial appraisal must also determine whether resulting carbon-related value is captured by the exporter or initially benefits the EU importer. A reduction in an importer’s potential CBAM certificate obligation does not automatically become additional revenue for the cement producer.
Banks should examine commercial arrangements through which any carbon-related benefit is recognised alongside contractual reliability of the electricity evidence. Financing assessments can distinguish between direct electricity-cost savings, recognised emissions improvements, and additional customer value supported by contractual commitments.
Customer carbon footprint reporting can draw on similar controlled power data
Verified electricity information can support cement manufacturers responding to customer reporting requirements beyond CBAM. European industrial buyers may request broader product carbon footprint calculations incorporating electricity consumption alongside other production-related emissions.
The same controlled electricity measurements, generation records, and procurement documentation can provide source information where relevant methodology permits their use. However, treatment of electricity inputs, production boundaries, and applicable emissions factors may differ between CBAM reporting and broader product-footprint frameworks.
Maintaining one reliable evidence base while preparing separate methodology-specific calculations allows cement exporters to support customs-related reporting, commercial product declarations, and corporate sustainability disclosures without assuming resulting carbon figures must be identical.
