The EU Carbon Border Adjustment Mechanism (CBAM), established by Regulation (EU) 2023/956, is a carbon pricing measure for imports into the EU. It ensures that imported goods face a carbon cost equivalent to that paid by EU producers under the EU Emissions Trading System (EU ETS), preventing carbon leakage — the risk that EU industries relocate production to countries with weaker climate policies.
CBAM is part of the EU's Fit for 55 package and the European Green Deal. It is the world's first carbon border adjustment mechanism of its scale.
Transitional Period
Oct 2023 – Dec 2025
Quarterly reporting of embedded emissions only. No payment required.
Definitive Regime
From 1 Jan 2026
Full payment required. Importers must purchase and surrender CBAM certificates annually.
CBAM Certificate Cost
Step 1: Total Emissions = Tonnage × Embedded Emissions (tCO2e/t)
Step 2: CBAM Cost = Total Emissions × Carbon Price (€/tCO2e)
Step 3: Net Cost = CBAM Cost − Carbon Price Credit (if any)
Example — Steel import
1,000 t × 1.8 tCO2e/t = 1,800 tCO2e
1,800 tCO2e × €85/tCO2e = €153,000
Cost per tonne: €153,000 ÷ 1,000 t = €153/tonne
Carbon price credit: Under Article 9 of the Regulation, if the exporting country already applies a carbon price (e.g. an ETS or carbon tax), this can be deducted from the CBAM cost. The deduction = effective carbon price paid abroad × embedded emissions.
Crude steel, flat/long products, pipes & tubes (CN chapters 72–73). Covers BF-BOF and EAF production routes.
Industry average — actual varies by production method and country
Primary and secondary aluminum, wrought & unwrought (CN chapters 75–76). High emissions due to energy-intensive Hall-Héroult electrolysis.
Primary aluminum average — secondary (recycled) is much lower
Electricity imports into the EU grid (CN chapter 27). Emission factor depends on the generation mix (coal, gas, nuclear, renewables).
No default — enter the specific emission factor for the exporting country's grid
Clinker and cement products (CN chapter 25). Process emissions from limestone calcination + fuel combustion in rotary kilns.
Global average — clinker ratio and fuel type affect actual emissions
Nitrogen fertilizers: ammonia, nitric acid, urea, mixed fertilizers (CN chapters 28, 31). High emissions from Haber-Bosch synthesis.
Nitrogen fertilizer average — ammonia production intensity varies by feedstock
Hydrogen and hydrogen-derived products (CN chapter 28). Emission factor varies sharply: grey (SMR ~9 tCO2e/t), blue (CCS ~2–3), green (<1).
No default — grey, blue, and green hydrogen have radically different footprints
50-tonne exemption — Regulation (EU) 2025/2083
Importers with ≤ 50 tonnes/year cumulative across iron/steel/aluminum/fertilizers/cement are fully exempt from all CBAM obligations (~90% of importers). Electricity and hydrogen are excluded from this exemption.
Importers above the 50-tonne threshold must:
Register as Authorised CBAM Declarant
Apply to your national competent authority before importing or before exceeding the 50-tonne threshold. Applications by 31 March 2026 allow continued imports until approval. Must be EU-established, financially solvent, and have no customs/tax irregularities.
Obtain verified embedded emissions
Gather verified data from the non-EU producer (CBAM Communication format). If unavailable, official default values (Reg. (EU) 2025/2621) apply — with a 10% markup in 2026, 20% in 2027, and 30% from 2028, to incentivise disclosure.
Purchase CBAM certificates (from Feb 2027)
Certificate sales begin February 2027. For 2026 imports, price = quarterly average EU ETS auction price. From 2027 imports, weekly averages apply. Certificates cannot be traded between importers.
Annual declaration — due 30 September
By 30 September of the following year, declare all imported CBAM goods and surrender corresponding certificates. First declaration (for 2026 imports): due 30 September 2027.
CBAM cost relative to commodity price varies dramatically by sector. Cement and fertilizers face the highest relative burden — CBAM adds costs approaching or exceeding the commodity's own market price, creating profound competitive consequences for non-EU producers in these sectors.
| Sector | Emission Factor | CBAM at €85 | Typical Price | CBAM % of Value |
|---|---|---|---|---|
| Steel | 1.8 tCO2e/t | €153/t | ~€600/t | ~26% |
| Aluminum | 8.0 tCO2e/t | €680/t | ~€2,200/t | ~31% |
| Cement | 0.8 tCO2e/t | €68/t | ~€80/t | ~85% |
| Fertilizers (urea) | 2.5 tCO2e/t | €213/t | ~€350/t | ~61% |
| Hydrogen (grey) | ~9.0 tCO2e/t | €765/t | ~€1,500/t | ~51% |
Commodity prices are indicative 2026 reference values (HRC for steel, LME for aluminum, EU export price for cement, urea CFR for fertilizers). CBAM % = CBAM cost at €85/tCO2e ÷ typical price. Actual impact depends on production route, energy mix, and Article 9 deductions. Source: EC, LME, FAO fertilizer data.
Key finding (May 2026): No country formally recognized yet
As of May 2026, the European Commission has not issued formal recognition of any third-country carbon pricing scheme under Article 9. EU importers cannot self-certify — a Commission implementing decision is required before any deduction can be applied.
Article 9 of Regulation (EU) 2023/956 allows the CBAM cost to be reduced by the effective carbon price already paid in the country of origin. A qualifying scheme must be: (1) legally binding and enforced, (2) cover the same sectors and emissions as CBAM, (3) not include export rebates. Commission Regulation (EU) 2025/2620 specifies eligible instruments.
| Country | Carbon Scheme | Price (2026) | Art. 9 Status |
|---|---|---|---|
| South Korea | K-ETS (since 2015) | ~€15–25/tCO2 | Pending |
| Switzerland | Swiss ETS (EU-linked) | ~€70/tCO2 | Exempt (Annex III) |
| United Kingdom | UK ETS | GBP 40–60/tCO2 | Pending |
| China | CN-ETS (electricity only) | ~€10–15/tCO2 | Does not qualify |
| Turkey | None (ETS in development) | €0 | Does not qualify |
| India | CCTS (pilot, not operational) | ~€1–2/tCO2 | Does not qualify |
| USA | No federal carbon price | €0 federal | Does not qualify |
| Russia | Token levy (no enforcement) | ~€0 | Does not qualify |
What this means in practice: Importers sourcing from South Korea should document K-ETS costs at the installation level now — if the Commission issues formal recognition before the 30 September 2027 declaration deadline, retroactive application may be possible. Turkish steel (the EU's largest single CBAM-affected import source) faces the full CBAM cost with no deduction. China's steel exports similarly have no qualifying deduction, as the CN-ETS covers only electricity.

CBAM enforcement is calibrated to match the EU ETS penalty regime. Under Article 26 of the amended Regulation (as updated by Reg. (EU) 2025/2083), two distinct penalty tracks apply:
Authorized declarant — failed surrender
€100 per tonne CO2e not surrendered by 30 September (same as EU ETS excess emissions penalty, Art. 16(3) Dir. 2003/87/EC). Paying the fine does NOT release the declarant from surrendering the missing certificates — the obligation carries forward to the following year's declaration.
Unauthorized importer — exceeded 50-tonne threshold
Higher penalties apply under Article 26(2a). A penalty is levied based on the total embedded emissions in all imports above the threshold made without Authorized CBAM Declarant status. Importantly, payment of this penalty does release the importer from the declaration and surrender obligation for those specific imports — unlike the declarant track.
Mitigating factors (Reg. (EU) 2025/2083)
National competent authorities may reduce penalties where: (a) the threshold was exceeded by no more than 10% of the 50-tonne limit; (b) the importer was awaiting declarant approval; (c) incorrect information was provided in good faith by a third party (producer, verifier, or carbon price certifier). Duration, gravity, intentional vs. negligent nature, and cooperation all weigh in the assessment.
Example — 1,000t steel, declarant misses deadline
CBAM cost owed: 1,800 tCO2e × €85 = €153,000
Non-surrender penalty: 1,800 tCO2e × €100 = €180,000
Total exposure: €333,000 + still must surrender 1,800 certificates in 2028

CBAM certificate prices are tied to the weekly average closing price of EU ETS allowances (EUAs). The price fluctuates based on macroeconomic conditions, energy prices, EU policy, and global climate negotiations.
For 2026, CBAM certificate prices use quarterly average EU ETS auction clearing prices (weighted by volume). From 2027, weekly averages apply. EEX publishes the official CBAM Reference Price every Friday.
