Serbian fertiliser manufacturers need to assess electricity, natural gas, ammonia inputs and process emissions together to establish the embedded carbon intensity of covered products under the EU’s Carbon Border Adjustment Mechanism (CBAM). Renewable electricity procurement can reduce one part of the reported footprint, but gas-intensive production routes and upstream materials may have a greater influence on the final result.
Under the current CBAM framework, indirect electricity emissions are included for covered fertiliser goods. The extent to which renewable power improves reported emissions depends on the specific product and its manufacturing route. Ammonia production can consume substantial quantities of natural gas, while downstream fertiliser processes combine precursor emissions, energy use and potentially other greenhouse gases.
An effective monitoring, reporting and verification (MRV) system must therefore connect energy consumption with production volumes, chemical inputs and the reporting treatment applicable to each covered product. This provides a stronger basis for investment decisions than a standalone renewable electricity target.
Mapping Production Routes and Gas Consumption
Manufacturers should begin by documenting their production routes, including whether ammonia is produced on site or purchased, how hydrogen is generated where relevant, which fuels and feedstocks are consumed, and which production lines manufacture covered goods. Electricity meters should be linked to the relevant processes rather than relying exclusively on site-wide consumption totals.
Natural gas requires particular attention because it can function as both a fuel and a feedstock. The accounting treatment may differ depending on how the gas is used and how its carbon enters the production process. Purchase invoices alone may not establish the required split, making flow meters, process models and mass balances necessary to reconcile consumption by function.
The carbon ledger should distinguish direct fuel emissions, process emissions, precursor emissions and indirect electricity emissions. Separating these components allows management to identify which interventions affect each part of the product footprint rather than applying a single blended emissions factor across the factory.
Ammonia Suppliers and Upstream Emissions
For plants purchasing ammonia, supplier information can be critical. Where actual emissions values are used, manufacturers should obtain the producing installation’s emissions data and verification status.
Switching to lower-emission ammonia may deliver a greater reduction in finished-product emissions than adding another increment of renewable electricity. Procurement decisions should therefore compare emissions information alongside price, product quality and delivery reliability.
Supplier concentration also creates a reporting risk. If one ammonia producer supplies most of a plant’s requirements but cannot provide verified data, a substantial share of finished production may have to rely on less specific information. Dual-sourcing decisions should consequently consider continuity of emissions data as well as physical supply security.
Imported precursor reporting requires advance coordination because upstream emissions reports may follow different schedules from the fertiliser plant’s own production records. Manufacturers should establish documented data cut-off dates and procedures for subsequent corrections rather than leave the entire report dependent on a late supplier submission.
Electricity Procurement and Production Efficiency
Electricity remains an important decarbonisation lever for compressors, pumps, granulation, cooling and material-handling equipment. On-site solar generation or a physical power purchase agreement (PPA) can reduce the indirect electricity component when the supporting evidence satisfies the applicable requirements.
Operational efficiency can reduce the electricity needed per tonne of product, lowering both energy costs and the renewable supply volume required to cover consumption. Electricity savings alone cannot resolve emissions arising from natural gas, precursor materials or process chemistry.
Fertiliser plants should also integrate laboratory and process-control data where emissions depend on product composition or operating conditions. Linking quality records to the carbon ledger can help explain whether changes in emissions intensity result from formulation, production efficiency or another process variable.
Production Variability and Investment Decisions
Shutdowns, production campaigns and changes in product mix can affect the emissions profile of fertiliser manufacturing. Annual averages may conceal differences between production periods, making monthly reconciliations of gas, electricity, precursor inputs and product output useful for verification and for identifying inefficiencies.
The ledger should separately identify carbon dioxide and other greenhouse gases arising from process chemistry and those resulting from fuel combustion. This distinction allows management to assess whether an efficiency project reduces fuel emissions without changing process emissions, preventing claims that overstate the overall improvement in product intensity.
Investment planning must also account for fertiliser-market cycles, volatile margins and the influence of energy costs on profitability. A long-term renewable electricity contract may stabilise one cost component while creating fixed financial commitments. Management should therefore assess electricity hedging, potential carbon benefits and production flexibility together.
Finally, carbon data should reconcile with the chemical mass balance already used for production and quality control. If feedstock carbon, gas consumption and product output do not align physically, the emissions calculation should not be finalised. This integrated approach helps Serbian fertiliser producers determine whether electricity procurement, feedstock substitution or process improvements offer the strongest basis for the next decarbonisation investment.
