The financial impact of the Carbon Border Adjustment Mechanism (CBAM) varies between cement and nitrogen fertiliser producers, reflecting differences in transport economics, production costs and customer purchasing patterns. Cement pricing is shaped by local supply conditions and delivery costs, while nitrogen fertiliser profitability is closely linked to natural gas prices, international trade and seasonal demand. Both sectors include products covered by CBAM, but the carbon cost applied depends on customs classification and the emissions covered under the relevant calculation approach.
CBAM charges also depend on the benchmark adjustment and eligible carbon-price deductions. The carbon cost is not uniform across all cementitious products or fertiliser formulations because product composition and manufacturing processes differ. For producers and investors, the key commercial issue is how much of the carbon-adjusted price can be recovered from customers without reducing sales volumes, which depends on each sector’s cost structure and market conditions.
Heidelberg Materials reports lower clinker incorporation in 2026
Heidelberg Materials reported a clinker incorporation factor of 67.8% in the first half of 2026, down from 68.5% a year earlier. The company said specific net emissions remained at 510 kg CO2 per tonne of cementitious material, according to its first-half 2026 presentation. It is pursuing measures that include lower clinker content and carbon capture technologies alongside exposure to carbon policy.
The group’s emissions indicator is described as information about the broader business and should not be treated automatically as a CBAM emissions factor for an individual imported product. Heidelberg Materials recorded first-half revenue of approximately €10.58 billion and operating EBITDA of €1.90 billion. The company’s results reflect an international building-materials portfolio that includes aggregates and ready-mixed concrete as well as cement, with earnings also influenced by regional construction demand.
CBAM exposure needs to be assessed at the relevant product and trade level rather than inferred from consolidated revenue or operating performance. This approach aligns with how CBAM calculations depend on customs classification and covered emissions for specific imports. It also reflects that an emissions indicator used in corporate reporting may not map directly to the emissions factor applied for a particular CBAM-covered shipment.
Cement competitiveness depends on delivered costs and demand
Cement has relatively low value compared with transport costs, making delivery distance, terminal access and handling important determinants of competitiveness. If carbon costs increase the delivered price of competing imports, domestic producers may have room to improve selling prices or increase capacity utilisation. The size of any advantage depends on demand conditions in each market.
In a weak construction market, customers may respond to higher prices by reducing purchases or switching to alternative materials rather than accepting the full carbon-related increase. An illustrative €8 per tonne improvement in margin across 3 million tonnes of cement sales would generate €24 million before additional costs. The actual return would vary if achieving that margin improvement required investment such as a new terminal, kiln expenditure or long-term commitments for carbon transport.
Infrastructure requirements can also affect when emissions-reduction projects translate into cash flow. A reduction in emissions does not necessarily lead immediately to additional cash flow if supporting infrastructure and capital expenditure remain necessary. These timing effects are relevant for how quickly carbon-related cost changes can be reflected in financial outcomes.
Fertiliser decarbonisation links to ammonia sourcing and seasonal buying
Fertiliser producers face different commercial variables under CBAM-linked cost changes. Natural gas prices influence ammonia production costs, while ammonia procurement affects finished-product economics depending on each company’s assets and product configuration. The ability to substitute imported ammonia for internally produced material therefore varies between producers.
Yara reported in its second-quarter 2026 presentation that its emissions footprint was below the average for CBAM importers. The company identified ways to reduce carbon costs, including sourcing low-carbon ammonia and developing the Sluiskil carbon capture project targeting capture of up to 800,000 tonnes of CO2 from mid-2026. The 800,000-tonne figure represents a stated capture target rather than a verified volume already captured.
Yara also reported that higher margins more than offset lower volumes during the quarter. Volatile nitrogen prices delayed some off-season purchasing, highlighting how seasonal buying patterns affect demand alongside changes in European carbon policy. These factors influence how quickly any carbon-adjusted cost changes can be reflected in sales volumes during purchasing periods.
Carbon pass-through depends on farmers’ ability to pay
An importer facing higher carbon-adjusted fertiliser costs may seek recovery through distributors and farmers, but pass-through depends on buyers’ ability and willingness to pay. When expectations for crop revenues are weak, farmers may postpone purchases or change fertiliser application plans. Producers then face decisions about holding inventory versus reducing prices to maintain sales, with consequences for working capital and margins.
The timing of purchases becomes particularly important because delayed orders can affect sales volumes and inventory requirements during the relevant purchasing season. Even where producers can recover some additional carbon cost, delayed orders can still alter near-term financial outcomes tied to inventory levels. In fertilisers, energy costs, ammonia sourcing, international price movements and the agricultural purchasing cycle all influence how much of the carbon-related expense can be passed through.
Southeast European exporters face pricing risks tied to CBAM data
For exporters in Southeast Europe, competitive gas costs or favourable local logistics can help preserve access to European markets under CBAM-linked pricing pressures. However, emissions evidence and precursor data used for CBAM calculations affect what EU buyers receive in offers for specific products. If European sales become less competitive, exporters may redirect volumes to other destinations.
Changes in trade flows can affect prices in alternative markets depending on volumes involved and conditions in those destinations. For cement producers, competitiveness depends on local delivered-cost factors, construction demand and investment required to support emissions reductions. For fertiliser producers, profitability depends more directly on competitive energy and ammonia supply as well as access to buyers during seasonal demand periods.
Across both sectors, the financial benefit from carbon-adjusted pricing depends on how much additional revenue remains after production costs and how customers respond to higher prices. Customer responses are shaped by market conditions such as construction demand for cement and seasonal purchasing behaviour for fertilisers. These dynamics determine whether carbon-related cost increases translate into retained margin or reduced sales volumes.
