The Carbon Border Adjustment Mechanism, or CBAM, is often discussed as a climate-policy tool designed to level the carbon-cost playing field between EU producers and certain imports.
For companies that buy affected goods, however, the more immediate reality is operational: CBAM is becoming a procurement cost.
The definitive CBAM regime began on 1 January 2026. Importers of covered goods need to be authorised CBAM declarants, calculate and report embedded emissions, and acquire and surrender CBAM certificates. The initial scope covers cement, iron and steel, aluminium, fertilisers, electricity and hydrogen.
The cost may not yet appear as a familiar invoice line on every purchasing dashboard. But the information required to determine that cost is being created—or lost—now.
The issue is not simply “how much carbon?”
A procurement team may know the purchase price, delivery terms, tariff code and supplier location. It may not know the emissions intensity of the facility producing the material, the calculation methodology used, the carbon price paid in the country of origin, or whether the supplier can provide data in a format that supports CBAM reporting.
Those gaps matter because carbon performance can influence the total cost of imported goods.
A supplier offering a cheaper base price but high embedded emissions may become less competitive once CBAM certificate costs are considered. Conversely, a supplier with better production data, lower-emissions processes or recognised carbon pricing may become more attractive—even if their initial unit price is higher.
That shifts CBAM from a compliance matter at the edge of the business to a factor in sourcing strategy.
Procurement, finance and customs need one view
CBAM responsibilities frequently fall into an awkward gap between departments.
Customs or trade teams understand declarations and import structures.
Procurement manages suppliers and commercial terms.
Finance models cost exposure and provisions.
Sustainability or technical teams assess emissions methodologies.
Legal teams review contractual rights and information obligations.
The problem is not lack of expertise. It is the absence of a shared operating model.
A company may import a covered product through multiple legal entities, use brokers, buy through distributors, or receive goods under different Incoterms. The entity making the customs declaration may not be the one negotiating with the producer. That makes it essential to map the real flow of goods, data and liability.
Start with an import and supplier exposure map
The first practical step is to identify where CBAM exposure exists today.
For each material or product category, companies should determine:
The relevant commodity code and whether it falls within scope.
The importing legal entity.
The country and facility of production, where known.
The supplier and any intermediaries.
Import volumes and projected spend.
Available embedded-emissions data.
Carbon prices already paid in the country of origin.
The contractual right to request, verify and update the information.
This map should not become a static spreadsheet held by one team. It should support purchasing decisions, budget planning, supplier engagement and board oversight.
Supplier conversations need to change
In the transitional phase, some companies treated CBAM data as a periodic reporting request. That approach is no longer enough.
Suppliers should understand that embedded-emissions information is becoming part of commercial competitiveness.
Procurement functions may need to include CBAM requirements in tenders, onboarding processes, framework agreements and contract renewals.
The most useful supplier conversations are specific. Rather than asking for “your emissions data,” companies should request information that matches the covered goods, relevant production facilities and required CBAM methodology.
They should also agree on:
Data format and reporting frequency.
Who is responsible for calculation and verification.
The treatment of missing or estimated data.
Rights to audit or challenge material changes.
Processes for passing through or sharing CBAM-related costs.
Finance needs a forward view
CBAM will increasingly affect budgets, margins and pricing decisions.
Finance teams should model exposure under several scenarios: changes in import volumes, carbon prices, supplier emissions intensity, availability of verified data, and potential pass-through of costs. This is especially important in sectors where carbon-intensive materials are embedded in products or projects with long lead times.
The board-level question is not simply whether the company can comply. It is whether the company understands the carbon-cost sensitivity of its supply chain well enough to make better sourcing and pricing decisions.
The opportunity
CBAM will create administrative work. But it also creates a clearer commercial signal.
Businesses that can identify imported emissions, compare suppliers on a carbon-adjusted cost basis and engage early with producers will have more options. They may be able to renegotiate contracts, redesign material choices, consolidate sourcing, improve forecasting or select lower-carbon inputs before cost pressure becomes acute.
The businesses that wait may find that their first CBAM bill is not the biggest problem. The bigger problem may be learning too late that they do not have the data or supplier leverage needed to manage it.
