IN Brief:
- The European Commission has published draft CBAM rules on carbon prices paid in third countries.
- The draft framework addresses proof of payment, currency conversion, and eligible certification.
- Importers of CBAM-covered goods face more detailed supplier data, emissions, and cost-verification requirements.
The European Commission has published draft rules on how carbon prices paid outside the EU can be converted into reductions of Carbon Border Adjustment Mechanism liabilities, pushing CBAM further into procurement, customs, and supplier-management processes.
The draft implementing act covers Article 9 of the CBAM regulation, which allows authorised CBAM declarants to reduce the number of CBAM certificates they surrender where a carbon price has already been paid in the country of origin for the embedded emissions declared. The consultation documents set out the mechanics of that deduction, including proof of payment, currency conversion, and the eligibility of third-party certifiers.
The Commission opened the initiative for four weeks of public feedback after earlier evidence-gathering from businesses, associations, public authorities, NGOs, academics, and stakeholders in EU and non-EU markets. Engagement was strongest from iron and steel, electricity, aluminium, and chemical-related sectors, reflecting the industries most directly exposed to CBAM compliance and cost allocation.
CBAM has moved beyond its transitional reporting phase. Since the definitive regime began in 2026, importers have needed processes that can support certificate purchases, declarations, and deductions. Procurement teams must now understand whether a supplier’s product is inside CBAM scope, whether emissions data is usable, and whether evidence of a carbon price paid outside the EU can be accepted.
Carbon prices paid under third-country emissions trading schemes or carbon taxes are expected to sit at the centre of the deduction process. The treatment of international carbon credits is more constrained, with high-integrity credits linked to Article 6 of the Paris Agreement treated differently from broader voluntary-market offsets. That distinction is intended to prevent weak credits from reducing CBAM liabilities without a credible connection to actual carbon pricing.
The practical workload will run across purchasing, customs, finance, and sustainability teams. Proof of payment must be traceable, currency conversion must be consistent, and rebates or compensations need to be identified so the effective carbon price is not overstated. Certification also has to be credible enough for EU authorities while remaining workable for non-EU manufacturers feeding European supply chains.
CBAM-covered goods sit deep inside industrial supply chains. Steel, aluminium, cement, fertilisers, hydrogen, electricity, and related inputs feed machinery, infrastructure, packaging, construction, energy, automotive, and manufacturing networks. A supplier with a lower unit price but weak emissions evidence may carry a higher landed-cost risk than a more expensive supplier with cleaner data and stronger verification.
That direction was already visible in Unpacked: January 2026, where CBAM’s definitive regime was treated as a procurement challenge rather than a distant compliance exercise. The new draft adds further weight to that shift. Carbon evidence is becoming a commercial input into sourcing decisions, customs filings, supplier negotiations, and landed-cost modelling.
Supplier contracts may need clearer clauses on emissions-data provision, audit rights, carbon-price evidence, and responsibility for inaccuracies. Importers will also need to decide when default values are acceptable and when actual values are required to manage cost exposure. In multi-tier supply chains, the difficulty rises quickly because the importer may not have a direct relationship with the producer generating the embedded-emissions data.
The draft also points to a more fragmented global carbon-pricing environment. Exporters in jurisdictions with recognised carbon-pricing systems may have a clearer path to deduction, while suppliers operating without robust evidence could leave EU importers exposed to higher certificate obligations. Foreign climate policy, supplier documentation, and EU landed cost are becoming tightly connected.
For logistics operations, CBAM will influence more than customs paperwork. Product classification, origin management, supplier onboarding, freight routing, and inventory decisions can all be affected once carbon cost becomes part of import economics. Companies with stronger product data, cleaner supplier records, and earlier procurement involvement will be better placed than those trying to retrofit evidence once consignments are already moving.
